Abstract:
Recent studies show that structures with triply periodic minimal surfaces (TPMS) provide enhanced mechanical, acoustical, and energy abortion performance. Previously, we have shown that breaking the symmetry of the gyroid lattice—one of the most used TPMS geometry—results in the creation of directional and polarized bandgaps. Here, we focus on the effect of breaking symmetry on the effective wave speeds of the gyroid structure. We analyze the wave speeds of different asymmetric gyroid lattices using the finite element analysis approach. Our analysis shows that certain gyroid asymmetries result in the transverse waves propagating faster than the longitudinal waves in particular direction. Our research shows that breaking the symmetry leads to previously unobserved anomalous polarization of elastic waves in asymmetric gyroids.

Abstract:
The wing scales of the Green Hairstreak butterfly Callophrys rubi consist of crystalline domains with sizes of a few micrometers, which exhibit a congenitally handed porous chitin microstructure identified as the chiral triply periodic single-gyroid structure. Here, the chirality and crystallographic texture of these domains are investigated by means of electron tomography. The tomograms unambiguously reveal the coexistence of the two enantiomeric forms of opposite handedness: the left- and right-handed gyroids. These two enantiomers appear with nonequal probabilities, implying that molecularly chiral constituents of the biological formation process presumably invoke a chiral symmetry break, resulting in a preferred enantiomeric form of the gyroid structure. Assuming validity of the formation model proposed by Ghiradella H (1989) J Morphol 202(1):69–88 and Saranathan V, et al. (2010) Proc Natl Acad Sci USA 107(26):11676–11681, where the two enantiomeric labyrinthine domains of the gyroid are connected to the extracellular and intra-SER spaces, our findings imply that the structural chirality of the single gyroid is, however, not caused by the molecular chirality of chitin. Furthermore, the wing scales are found to be highly textured, with a substantial fraction of domains exhibiting the <001> directions of the gyroid crystal aligned parallel to the scale surface normal. Both findings are needed to completely understand the photonic purpose of the single gyroid in gyroid-forming butterflies. More importantly, they show the level of control that morphogenesis exerts over secondary features of biological nanostructures, such as chirality or crystallographic texture, providing inspiration for biomimetic replication strategies for synthetic self-assembly mechanisms.

Abstract:
Gyroid structure, a nature inspired cellular architecture, is under extensive exploration recently due to its structure continuity, uniform stress distribution under compression, and stable collapse mechanism during deformation. However, when combining with a functional gradient, the Gyroid structure can perform much different mechanical behavior from its homogeneous counterpart. Herein, bottom-up computational modeling is performed to investigate the mechanics of functional gradient nano-gyroid structure made of copper (Cu). Our work reveals that its mechanical properties degrade with a density that is much slower than those of homogeneous gyroid structure. The scaling of yield strength [Formula: see text] to the relative density [Formula: see text] for the functional gradient gyroid structure is in the factor of 1.5. Moreover, the layer-by-layer collapsing mechanism yields significantly better mechanical energy absorption ability. This study not only leads to insightful understanding of the deformation mechanisms in nonuniform gyroid structures but also promotes the development of the functional gradient cellular materials.

Abstract:
Bio-inspired functionally graded cellular materials (FGCM) have improved performance in energy absorption compared with a uniform cellular material (UCM). In this work, sheet-based and strut-based gyroid cellular structures with graded densities are designed and manufactured by stereo-lithography (SLA). For comparison, uniform structures are also designed and manufactured, and the graded structures are generated with different gradients. The mechanical behaviors of these structures under compressive loads are investigated. Furthermore, the anisotropy and effective elastic modulus of sheet-based and strut-based unit gyroid cellular structures are estimated by a numerical homogenization method. On the one hand, it is found from the numerical results that the sheet-based gyroid tends to be isotropic, and the elastic modulus of sheet-based gyroid is larger than the strut-based gyroid at the same volume fraction. On the other hand, the graded cellular structure has novel deformation and mechanical behavior. The uniform structure exhibits overall deformation and collapse behavior, whereas the graded cellular structure shows layer-by-layer deformation and collapse behavior. Furthermore, the uniform sheet-based gyroid is not only stiffer but also better in energy absorption capacity than the uniform strut-based gyroid structure. Moreover, the graded cellular structures have better energy absorption capacity than the uniform structures. These significant findings indicate that sheet-based gyroid cellular structure with graded densities have potential applications in various industrial applications, such as in crashworthiness.

Abstract:
Human trabecular bone is known to be structurally very complex. The geometrical distribution of trabecular bone has major effects on its ability to perform its physiological function of load-bearing efficiently. Idealized unit cell models are very helpful in understanding the significance of micro-level properties on macro-level behavior. There is a need for a simple method to model trabecular bone, such that micro-level phenomena (like buckling) can be studied. We investigate a new model for trabecular bone, based on a minimal surface solid called a gyroid. The gyroid-based model is computationally easy to implement, and generates structures that possess strong morphometric and mechanical resemblance to real trabecular bone. We generated gyroid models for a range of volume fractions, representing trabecular bone samples obtained from various anatomic sites and ages. Finite element analysis was performed to obtain the mechanical properties of the gyroid structures. We calculated the small-strain elastic moduli values for each of the gyroid models and plotted these against corresponding apparent density. A power-law relationship was obtained for the gyroid models, in accordance with published studies on real trabecular bone mechanical behavior. The results showed that the gyroid could provide a suitable model for studying the effects of variations in trabecular structure on macro-level bone behavior.

Abstract:
Additively manufactured Ti scaffolds have been used for bone replacement and orthopaedic applications. In these applications, both morphological and mechanical properties are important for their in vivo performance. Additively manufactured Ti6Al4V triply periodic minimal surface (TPMS) scaffolds with diamond and gyroid structures are known to have high stiffness and high osseointegration properties, respectively. However, morphological deviations between the as-designed and as-built types of these scaffolds have not been studied before. In this study, the morphological and mechanical properties of diamond and gyroid scaffolds at macro and microscales were examined. The results demonstrated that the mean printed strut thickness was greater than the designed target value. For diamond scaffolds, the deviation increased from 7.5 μm (2.5% excess) for vertical struts to 105.4 μm (35.1% excess) for horizontal struts. For the gyroid design, the corresponding deviations were larger, ranging from 12.6 μm (4.2% excess) to 198.6 μm (66.2% excess). The mean printed pore size was less than the designed target value. For diamonds, the deviation of the mean pore size from the designed value increased from 33.1 μm (−3.0% excess) for vertical struts to 92.8 μm (−8.4% excess) for horizontal struts. The corresponding deviation for gyroids was larger, ranging from 23.8 μm (−3.0% excess) to 168.7 μm (−21.1% excess). Compressive Young’s modulus of the bulk sample, gyroid and diamond scaffolds was calculated to be 35.8 GPa, 6.81 GPa and 7.59 GPa, respectively, via the global compression method. The corresponding yield strength of the samples was measured to be 1012, 108 and 134 MPa. Average microhardness and Young’s modulus from α and β phases of Ti6Al4V from scaffold struts were calculated to be 4.1 GPa and 131 GPa, respectively. The extracted morphology and mechanical properties in this study could help understand the deviation between the as-design and as-built matrices, which could help develop a design compensation strategy before the fabrication of the scaffolds.

Abstract:
We have developed a novel, facile and architecturally versatile fabrication method for specially designed cellular graphene lattices using additively manufactured polymer-based gyroidal triply periodic minimal surface (TPMS) as the initial sacrificial scaffold. Three-dimensional (3D)-printed templates of the polymeric gyroid lattices were coated with a mixture of graphene oxide (GO) and hydrazine solution via the hydrothermal process, followed by drying and thermal etching of the polymer scaffold, which resulted in a neat reduced GO (rGO) lattice of the gyroidal TPMS structure. Scanning electron microscopy and micro-computed tomography were used to evaluate the morphology and size of the 3D rGO architectures, while a Raman response at 1360[Formula: see text]cm[Formula: see text] (D peak), 1589[Formula: see text]cm[Formula: see text] (G peak) and 2696[Formula: see text]cm[Formula: see text] (2D peak) verified the presence of rGO. Thermo–electro–mechanical properties of rGO gyroid lattices of different densities were characterized where the highest Young’s modulus recorded was 351[Formula: see text]kPa for a sample with a density of 45.9[Formula: see text]mg[Formula: see text][Formula: see text][Formula: see text]cm[Formula: see text]. The rGO gyroid lattice exhibits an electrical conductivity of 1.07[Formula: see text]S[Formula: see text][Formula: see text][Formula: see text]m[Formula: see text] and high thermal insulation property with a thermal conductivity of 0.102[Formula: see text]W[Formula: see text][Formula: see text][Formula: see text]m[Formula: see text][Formula: see text]K[Formula: see text]. It is demonstrated that the hydrothermal-assisted fabrication process is adaptable for different lattice architectures based on 3D-printed scaffolds and thus has wide functional applications.

Abstract:
The thesis investigates the mechanical properties of gyroid structures through various experiments and simulations. Gyroid structures consist of an intricate mesh of surfaces and can differ in density and cell size. The mechanical properties of the gyroid structure are inevitably dependent on the density. A convergence between density and the resulting mechanical stiffness of the lattice structure could be applied to a wide range of industrial components. To test the mechanical properties of gyroid structures 3D-printed cubes are compressed in a test machine where stiffness is measured for a range of cubes with different density. The tests are confirmed by a finite element analysis (FEA) and all data is precisely analysed thereafter. A linear increase in density results in a non-linear increase in stiffness where the region between 30 % and 60 % density yields particularly good results. After evaluating results from experiments and simulations, gyroid structure is implemented in one of ABB’s components for a circuit-breaker system to further display its advantages. Four different concepts are presented for the component where the most promising concept reached a weight reduction of 30 percent just by adding gyroid structures. No other design alterations have been made to the component. The results show great potential of being able to reduce the plunger’s weight whilst maintaining desired stiffness. The results of the thesis can be applied widely to develop new methods of optimizing industrial components with additive manufacturing as the gyroid doesn’t need any supportive structure. It is possible to blend gyroid surfaces with other optimization tools such as topology optimization or grading to achieve even higher degrees of weight reduction.
Tesen undersöker de mekaniska egenskaperna av gyroidstrukturer genom olika experiment och simuleringar. Gyroidstrukturer består av ett komplext nätverk av ytor och kan variera i densitet och cellstorlek. Dess hållfasthetsegenskaper är givetvis beroende på densiteten. Konvergensen mellan densitet och den resulterande mekaniska styvheten av nätverksstrukturen skulle kunna tillämpas på ett brett spektrum av industriella komponenter. Det är möjligt att reducera vikt eller öka styvhet medan att kunna bibehålla hållfastheten. För att testa hållfasthetsegenskaperna av gyroidstrukturer 3D-printade kuber komprimeras i en tryckmaskin där styvhet mäts för ett antal kuber med olika densitet. Testen bekräftas genom en analys med finita elementmetoden (FEM) och all data utvärderas noggrant därefter. En linjär ökning i densitet leder till en ickelinjär ökning i styvhet där området mellan 30% och 60% densitet ger ett särskilt bra förhållande mellan styvhet och vikt. När resultatet från experimenten och analysen utvärderats, implementeras gyroidstruktur på en av ABB’s komponenter i en strömbrytare för att ytterligare visa dess fördelar. Fyra olika koncept presenteras där det mest lovande konceptet kunde viktoptimeras med 30 procent endast genom att tillägga gyroidstrukturer. Inga andra designändringar har gjorts på komponenten. Resultatet demonstrerar en stor potential när det gäller att viktreducera komponenten utan att tappa nödvändig styvhet. Resultaten av tesen kan användas på många olika sätt för att ta fram nya metoder för optimering av industriella komponenter med additiv tillverkning då gyroiden inte behöver några stödstrukturer. Det är möjligt att blanda gyroidstrukturer med andra optimeringsverktyg såsom topologioptimering eller gradering för att åstadkomma ännu större viktminskningar.

Abstract:
The objective of this work, concerning the template-assisted patterning of functional materials on the nanoscale to enhance specific material properties, is five-fold. Firstly, to develop a highly reproducible synthesis pathway for large quantities of double- gyroid-forming diblock copolymers. Secondly, to replace the previously used fluo- rinated monomers with an inexpensive and environmentally sustainable alternative making large-scale applications feasible. Thirdly, to establish a reliable and fast fabri- cation technique for fully porous gyroidal templates. Fourthly, to replicate these tem- plates with inorganic as well as organic functional materials using electrochemical and atomic layer deposition. Finally, to apply and characterize these novel double-gyroid- structured materials in devices such as photovoltaic devices, electrochromic displays, and supercapacitors. The first part of this thesis introduces the different techniques of modern nanotechnol- ogy employed in three-dimensional nanopatterning of functional materials and seeks to highlight the possibilities and advantages of using self-assembled, mesoporous polymeric templates for this purpose. Chapter 2 explores the fascinating gyroidal intermaterial dividing surfaces formed by self-assembling systems, such as microphase separating di- block copolymers. Chapter 3 focuses on the synthesis of double-gyroid-forming diblock copolymers consisting of poly(4-X-styrene) and poly(lactic acid) via atom transfer radi- cal and organocatalytic ring-opening polymerization using a bifunctional initiator. The preparation of mesoporous templates with double-gyroid morphology based on a rapid thermal annealing protocol is described in Chapter 4. Importantly, it is shown that copolymers prepared from inexpensive, non-substituted styrene can yield fully porous thin films. Chapter 5 reports the template-assisted electrodeposition of metal oxides, such as V2O5, using the previously prepared voided styrenic templates. Further, the perfor- mance of these materials as electrodes in electrochromic displays and supercapacitors is tested. Chapter 6 describes an alternative approach to obtain double-gyroid-structured metal ceramics via the post-nanostructuring thermal oxidation of electroplated metals. Nickel is chosen to demonstrate this highly versatile fabrication route and to study the nanoscale Kirkendall effect of three-dimensional structures. Further, the electrochromic performance of NiO is investigated. Chapter 7 deals with yet another electrodeposition technique, namely the electropolymerization of conjugated polymers. Identification of suitable solvents for the templated electrosynthesis and the subsequent template dis- solution enable the three-dimensional nanopatterning of PPy, PEDOT, and PT. The refilling of the organic template via atomic layer deposition, including the necessary chemically modification of the styrenic scaffold for an improved thermal resistance and surface functionality, is discussed in Chapter 8.

The thermal bridge problem in building fagades has become a topic of interest as the energy performance of building enclosure design required improvements with a global lead in sustainable building design. Curtain wall fagade systems are widely used for recent high-rise buildings, and the thermal bridge issue occurs mainly within the aluminum frame of the curtain wall system. In addition to the thermal bridging effects, the conventional curtain wall fagade designs have limitations in increasing the stiffness of the mullion. As to address the lack of an innovative solution to solve both issues, this thesis proposes utilizing a cellular structure in mullion design. In particular, this thesis has selected a single-gyroid structure, which is an open cell foam structure that has the minimum surface area necessary to span a region of space. The thesis explores various aspects of the application that extend from a rapid modeling method of gyroid structure, experiments, and simulations along with theoretical values for mechanical and thermal properties of gyroid, to topology optimization of the various densities of gyroid in the composite structure. The results are expected to improve the curtain wall designs with future experimental verifications.

Abstract:
This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. Triply periodic minimal surfaces (TPMS) are mathematically defined surfaces that partition space and present a large surface area in a confined space. These surfaces have analogues in many physical systems. The endoplasmic reticulum (ER) can form intricate structures and it acts as a replica for the wing scales of the butterfly C. rubi, which is characterized by electron microscopy and reflectometry. It was shown to contain a photonic crystal and an analogue to a TPMS. These photonic crystals have been replicated in silica and titania, leading to blue scales with replication on the nanometer scale. Replicas analyzed with left and right handed polarized light are shown be optically active. A macroporous hollow core particle was synthesized using a double templating method where a swollen block copolymer was utilized to create polyhedral nanofoam. Emulsified oil was used as a secondary template which gave hollow spheres with thin porous walls. The resulting material had a high porosity and low thermal conductivity. The areas of inorganic materials and functional biomolecules were combined to create a functional nanoporous endoskeleton. The membrane protein ATP synthase were incorporated in liposomes which were deposited on nanoporous silica spheres creating a tight and functional membrane. Using confocal microscopy, it was possible to follow the transport of Na+ through the membrane. Yop1p is a membrane protein responsible for shaping the ER. The protein was purified and reconstituted into liposomes of three different sizes. The vesicles in the 10-20 nm size range resulted in tubular structures. Thus, it was shown that Yop1p acts as a stabilizer of high curvature structures.

At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Manuscript. Paper 3: Submitted. Paper 4: Submitted. Paper 5: Submitted.

Abstract:
Immunoassayer är en väldigt vanlig metod för koncentrationsbestämning av biomolekyler. Denna metod nyttjar antikroppars affinitet för vissa analyter. I detta projekt har det undersökts om Gyros AB:s detektionsinstrument kan göras känsligare. Flera förslag har tagits fram genom efterforskning i artiklar och intervjuer med personer insatta inom området. De metoder som projektgruppen valt att presentera för företaget är enzymbaserad immunoassay med fluorescerande substrat samt multipel inmärkning av antikroppar, vilket vi tror kommer bidra till att försärka den fluorescerande signalen. Immobilisering av antikroppar med hjälp av traptavidin är ytterligare ett framtaget förbättringsförslag som syftar till att bidra med starkare och förlängd immobilisering av antikroppar till den fasta fasen i immunoassay. Flertalet andra metoder har undersökts såsom detektion med hjälp av radioaktivitet och kemiluminiscens. Inga fortsatta studier gjordes på grund av svårigheter att anpassa metoderna till de nuvarande instrumenten. Vi tror att de förslag på metodförbättringar som vi föreslår kan förbättra känsligheten på Gyros mätningar om de implementeras på den nuvarande plattformen.

Abstract:
Modal scrambling is a source of noise and signal fading in fiber-optic gyros1 and therefore the best fiber-optic gyros use single-mode polarization preserving fiber and couplers2. Phase-conjugation can be used to correct for modal scrambling3-5 and to make fiber-optic gyros6-9. In this paper we describe and demonstrate the combination of these two possiblities; a phase-conjugate fiber-optic gyro using multimode fiber.

Abstract:
Abstract As the flexibility and reliability of additive manufacturing (AM) and its corresponding design tools increases, it is becoming a viable option for more industries. One application area that could benefit from AM is composite component manufacture. The layup and molding of composite materials face significant challenges presented by tight design timescales, growing demand for productivity, and the complexity of components and end products. Therefore, there is an immediate potential to save energy by reducing the mass of the curing equipment and tooling to enhance process heat transmission. The goal of this paper is to demonstrate the reduction of embodied energy within mold tools that are printed using an AM process. Using an AM approach, it is possible to design lightweight curing tools to increase the curing rate and quality of heat distribution in the mold. The viability of additively producing these cure tools was assessed by analyzing the geometrical precision of the composite mold outputs, material utilization, and heat transmission qualities of each sample. In this study, 14 cure tools were designed and manufactured with a 100 mm2 curing surface area, top plate thickness of 1–2 mm, and stiffening lattices behind the curing surface with a depth of 10 mm. Four lattice geometries, gyroid, dual-wall gyroid, planar diamond, and stochastic, were tested based on their overall geometrical accuracy and thermal responsiveness. While the stochastic lattice had the best single tool properties, the planar diamond and gyroid lattice tools had better potential for future use in the design of additively manufactured composite tooling.

Abstract:
Additive manufacturing (AM) processes enable the creation of lattice structures having complex geometry which offer great potential for designing light weight parts. The combination of AM and cellular lattice structures provide promising design solutions in terms of material usage, cost and part weight. However, the geometric complexity of the structures calls for a robust methodology to incorporate the lattices in parts designs and create optimum light weight designs. This paper proposes a novel method for designing light weight variable-density lattice structures using gyroids. The parametric 3D implicit function of gyroids has been used to control the shape and volume fraction of the lattice. The proposed method is then combined with the density distribution information from topology optimization algorithm. A density mapping and interpolation approach is proposed to map the output of topology optimization into the parametric gyroids structures which results in an optimum lightweight lattice structure with uniformly varying densities across the design space. The proposed methodology has been validated with two test cases.
