Abstract:
Projects that require viewing dozens or hundreds of specimens often include countless hours for specimen preparation. Specimens are often affixed to metal or carbon stubs with conductive tape, paint or paste (Rampley, 1976; Witcomb, 1981). The use of conductive paint or paste requires substantial mounting and drying times prior to coating with conductive metal or carbon and observation in a scanning electron microscope (SEM). We here describe a simpler protocol for mounting specimens to expedite specimen preparation.During a recent study, where cryofractured salmon egg membranes were mounted on edge to view transverse sections, we needed an expedient method of specimen mounting to quickly view hundreds of samples. We experimented with mounting specimens in metal putty, a product used by fishermen for weighting fishing line. The methodology described here solved some of the problems of messy specimen mounting and eliminated the need to wait for curing before coating and observation.

Abstract:
Specimen support grids are now almost universally 3.05 mm in diameter, except for a few high resolution stages and some very old instruments. They are available in a vast range of materials and designs. One catalogue lists 86 types in a total of 10 materials. The reason for this proliferation is to enable one to control the following:(a)the amount of support the specimen needs (unsupported areas range from 20 pm to 1 mm in extent);(b)the material of the grid, so that it neither interferes with X-ray analysis nor reacts with the specimen;(c)the labeling of specific regions of a specimen (many grids have identification marks for relocation of interesting fields).The cheapest most widely used supports are copper grids at a spacing of 100 bars in"1. Most grids have a shiny side and a dull side. Opinions differ as to the best side on which to mount the specimen but if a consistent practice is adopted it is always known which way up in the microscope the specimen was mounted.

Abstract:
This paper reports the new development of an optical microscope automatic focus control system (OMAFD) for the JXA-8800/8900 series Electron Probe Microanalyser (EPMA). In recent years, a method called “wide area mapping” has been increasingly used with EPMA for measurement of X-rays by moving the specimen to obtain 2-dimensional element distributions over large analysis areas. In mapping, the simultaneous acquisition of multiple elements is required. Using an optical microscope, which has a very small (about ±1 μm) depth of focus, the specimen surface needs to be vertically adjusted to the Rowland circle of a wavelength dispersive X-ray spectrometer. Even with flat specimens, actual analysis points often show some inclination. Specimens are often inclined accidentally during sample preparation and mounting. Moreover, requirements of specimen analysis with curved or irregular surfaces have been increasing.

Abstract:
Morphological studies of small invertebrates often involve the preparation of slides to observe minute body parts under a compound microscope. Preparation should facilitate observation, through traditional optical microscopy, of small surface structures on different planes, like pores, spines and setae. Various methods and techniques, using different mounting media that specialists have adopted to observe and preserve small crustaceans, have their advantages and disadvantages. Within the order Bathynellacea, specimens in the family Bathynellidae are particularly challenging due to their small size (0.5 to 2.25 mm body length) and very delicate exoskeleton, which tends to be completely digested when using common clearing mounting media, making future consultations impossible. Permanent slides are fundamental to preserve small specimens for scientific collections, because temporary slide preparations can easily result in the loss of body parts in the passage between slide and vial and vice versa. Dr Eugene Serban worked on Bathynellacea for more than 40 years, improving the preparation and preservation of delicate specimens using a stained glycerol-jelly and double cover slip mounting technique. His method is described here with a variation that speeds up the original procedure and was implemented in most recent years by one of the authors (A.I.C.). The technique provides excellent preservation and visualization of body parts on permanent slides, which do not need curation tasks and can last for many years.

Abstract:
The abilities of researchers to obtain high-quality images and other data from pin-mounted museum insect specimens using conventional scanning electron microscopy (SEM) are hindered by several necessary constraints. The specimens may represent unique exemplars (e.g., holotypes) upon which the taxon name rests. In some cases the specimen may no longer be extant in any environment outside the museum. Thus these insects must always be handled with extreme care,Tegardless of how they are to be observed.Normal preparation of an insect for SEM involves sputter coating it with a conductive metal to minimize the effects of charging, and conductive paint must be applied to an obscure or uninteresting area to complete the connection to the specimen mount and thus to ground. Generally, unless such specimens have been newly collected, they will have already been killed and allowed to air dry, with a mounting pin inserted through the thorax. The body of the insect shrinks against the pin, which cannot then be removed for observation and later reinserted without damage.

Abstract:
The effect of hot-mounting for metallographic studies of as-quenched low-carbon martensitic steels has been studied. Hot-mounting is typically carried out at 150–200 °C, i.e., a low-temperature tempering regime. Cold- and hot-mounted specimens from an as-quenched low-carbon auto-tempered steel were examined using a scanning electron microscope and their hardness levels were also compared. It was found that hot-mounting causes additional tempering that manifests as the appearance of new precipitates in those regions that are free of auto-tempered cementite. The observations were rationalized using DICTRA simulations to calculate the potential growth of cementite. Hot-mounting was also shown to cause a small but statistically significant increase in the hardness of the martensite.

Abstract:
Digitisation allows scientists rapid access to research objects. For transparent to semi-transparent three-dimensional microscopic objects, such as microinvertebrates or small body parts of organisms, available databases are scarce. Most mounting media used for permanent microscope slides deteriorate after some years or decades, eventually leading to total damage and loss of the object. However, restoration is labour-intensive, and often the composition of the mounting media is not known. A digital preservation of important material, especially types, is important and an urgent need. The Virtual Microscope Slide Collection – VIRMISCO project has developed recommendations for taking microscopic image stacks of three-dimensional objects, depositing and presenting such series of digital image files or z-stacks as an online platform. The core of VIRMISCO is an online viewer, which enables the user to virtually focus through an object online as if using a real microscope. Additionally, VIRMISCO offers features such as search, rotating, zooming, measuring, changing brightness or contrast, taking snapshots, leaving feedback as well as downloading complete z-stacks as jpeg files or video file. The open source system can be installed by any institution and can be linked to common database or images can be sent to the Senckenberg Museum of Natural History Görlitz. The benefits of VIRMISCO are the preservation of important or fragile material, to avoid loan, to act as a digital archive for image files and to allow determination by experts from the distance, as well as providing reference libraries for taxonomic research or education and providing image series as online supplementary material for publications or digital vouchers of specimens of molecular investigations are relevant applications for VIRMISCO.

Abstract:
AbstractAn account is given of the development of aqueous gum-chloral mounting media used for mounting small arthropods on microscope slides. Berlese’s fluid is shown to have never been used by Berlese and other formulae are shown to have been randomly attributed to various authors, often incorrectly. Erroneous formulae and modifications to formulae have been followed by subsequent workers without reference to their origin. Details of the five formulae currently recommended in the literature are given and serious problems are shown to have been encountered with all of them by many workers. In many collections throughout the world gum-chloral slides are steadily deteriorating and specimens becoming irretrievably lost. Those workers advocating the use of gum-chloral aqueous media continue to propose alternative techniques in an attempt to overcome the problems they admit still occur. It is recommended that these media be used only for temporary mounts and never for specimens of taxonomic significance.

Abstract:
An initial study into the use of the large chamber scanning electron microscope (LCSEM) to interrogate the surface microstructure evolution of metallic specimens has been carried out. The LC-SEM located at Western Kentucky University is the largest instrument of its type at any university in the world. As such, unique measurements can be performed due to the size of its chamber and extended view of its optic system. Strain was varied for each individual specimen, and imaged using Secondary Electrons within the gauge length as well as near the grip position. Results will show progression of surface microstructures and nickel content of metallic specimens. Additionally, results will demonstrate the capability of the LC-SEM to carry out these types of measurements. Future measurements will include the incorporation of an in-situ uniaxial load frame for dynamic studies.

In forward part, half-plane andsingle-layer/substrate specimens of ani- sotropic and linearly elasticmedia are considered; in inverse part, the V(z) curve is the muchprefered information for medium inversion. Based on which, the cost functions for optimization are constructed to invert the unknown par- ameter(s).

Abstract Transmitted-light methods reveal more details of the morphology of fiber-reinforced polymeric composites than are observable using any other available microscopy techniques. This chapter describes the various aspects relating to the selection and preparation of ultrathin-section specimens of fiber-reinforced polymeric composites for examination by transmitted-light microscopy techniques. The preparation steps covered are a selection of the rough section, preparation of the rough section for preliminary mounting, grinding and polishing the primary-mount first surface, mounting the first surface on a glass slide, and preparing the second surface (top surface). The optimization of microscope conditions and analysis of specimens by microscopy techniques are also covered. In addition, examples of composite ultrathin sections that are analyzed using transmitted-light microscopy contrast methods are shown throughout.

Abstract:
Mechanical properties of MEMS materials are crucial for MEMS performance and reliability. Micro scale mechanical test has been challenging to MEMS community, due to the difficulties in handling micro scale specimens. In this article, a novel micro mechanical tensile testing method has been developed in combining a stiff microscale specimen developed with MTS Tytron Micro Force Tester. The advantages of this method include that it is a standard direct test of micro machined specimens, simple boundary conditions, and easy specimen handling/mounting in characterization. A novel specimen with micro features has been designed and fabricated for the direct mechanical testing. The specimen consists of three micro beams in parallel. The width of the center beam is 40 μm and the outer two beams’ width is 90 μm. The length of all three beams is 4 mm long. An optimized design has been achieved with finite element analysis, which shows that 98% of the total deformation occurs on the beams’ gage length. The stress is uniformly distributed over the three beams with a difference less than 0.5% among them. Both UV-LIGA fabricated nickel and SU-8 specimens have been tested. The UV-LIGA fabricated nickel has fracture strength of 1000±70 MPa and the results of SU-8 show a brittle behavior with fracture strength of 48±3 MPa.

We have developed a novel bioreactor which can be mounted onto the stage of an inverted microscope which permits direct 600× observation of a perfused specimen while the specimen is held in either load or strain control. Further, the chamber has been designed to minimize free volume to reduce the cost of reagents.

Abstract:
We report on the use of local mechanical characterization techniques for the understanding of structural damage precursors in various material systems. Instrumented indentation and atomic force microscopy (AFM) were used to characterize local damage in: (1) fatigued metallic beams subject to non-linear vibration, (2) individual polymer and glass microfibers, and (3) additive manufactured thermoplastics. Indentation studies of the fatigued metallic beams showed a compliance effect of up to 40% in relatively highly stressed regions. An approved fiber mounting technique allowed for indentation of unmodified surfaces of single microfibers, while AFM modulus maps of the fibers reveal local regions of relative compliance. Local mechanical tests of 3-D printed acrylonitrile butadiene styrene specimens revealed a variation in properties between printed beads and bead-bead interfaces. The nano-/micro-scale techniques developed in the present study provide a framework for understanding how damage precursors may affect processing-structure-property relationships in present and future structural aerospace materials.

Abstract In a rollover accident, both rear axles of a Sports Utility Vehicle (SUV) were fractured adjacent to the wheel-mounting flange. The purpose of this paper is to describe the methodology and experimental techniques used in determining whether one or both axles failed prior to the accident, and thus contributing to the accident, or whether both axles failed as a result of the rollover and the ensuing impact with the highway. Scanning Electron Microscopy (SEM) technique was used to obtain detailed characteristics of the fracture surface on both axles. Through-thickness hardness profile of the axles was determined using incremental micro-hardness measurements in order to assess the depth of case hardening in both axles. Impact, tensile and fatigue specimens were machined from the remaining parts of the failed axles and were tested to destruction using standard impact (Izod), tensile and fatigue tests. The fracture surface characteristics of the test specimens were compared to those of the failed axles in order to isolate the mode of failure. Based on the results of the above tests, the history of the repair work performed on the rear wheel bearings and the physical evidence of various marks and damages remaining on the vehicle’s body, it was determined that one of the rear axles failed prior to the rollover, while the other occurred as a result of the rollover and ensuing impact with the highway.

Abstract:
Abstract This study is focused on the micromechanical properties of conventional rebar and how they could be used for comparison with the 3D printed rebar tensile and fatigue properties. Current trends in additive manufacturing hint at the eventual use of 3D printing in the construction of homes and office buildings. Nowadays, 3D printing of homes is being achieved on an experimental basis by depositing extruded concrete in layers up to the ceiling to make walls, and then building a roof on top of the walls by conventional methods. This practice is not suitable to make bridges, multistory office buildings or structures that substantially experience tensile stresses. It is necessary to incorporate steel rebar in otherwise easily printed concrete structures. One way to achieve this is direct welding of steel into concrete by mounting a welder gun on to the 3D printing head and conducting 3D welding of the rebar. This has been accomplished and mild steel weldments have been 3D welded onto concrete. To make it acceptable for construction, the reliability of such printed rebar must be investigated. Early results of microscale tensile and fatigue testing on steel weldments made by additive manufacturing show desirable mechanical properties. However, the comparison has been made with macroscale tensile and fatigue properties of conventional rebar. To ascertain the reliability of 3D printed rebar welded onto concrete, it is essential to conduct a comparison with the micromechanical properties of conventional mild steel rebar. To achieve this, micro-specimens were machined off thick and thin conventional rebar in various orientations including along and across the longitudinal axis of the rebar and at different depths from the surface to investigate their micromechanical properties. Dog-bone shaped specimens 1000-micron in gage length with square gage cross sections measuring 200-micron × 200-micron were extracted from the surface as well as from the center of thick and thin rebar rods using a HAAS CNC. Samples were polished to a mirror finish and then tested in an Instron Electropulse E1000 load frame equipped with microgrippers that allowed monotonic and cyclic loading of the samples at a frequency of 50Hz. The results of micromechanical testing obtained from conventional rebar are compared with the those obtained from testing micro-specimens machined from mild steel weldments deposited by 3D welding on ceramics. The results demonstrate the reliability of mild streel rebar printed by 3D welding onto concrete. The implications of the findings on the use of additive manufacturing in 3D printing reinforced concrete and how it will impact the construction industry are discussed.

Abstract Parallel lapping (often called delayering) is a commonly used process in failure analysis of integrated circuits. However, parallel lapping commonly gives rise to the issue of weak sample preparation method especially on specimen mounting. The traditional specimen mounting technique was done by mounted a single die to polishing fixture using drop of super glue. Using conventional methods, problems such as losing the die during polishing, serious edge rounding are often encountered. Further, loading the whole polishing fixture into Scanning Electron Microscopy machine for SEM imaging or Passive Voltage Contrast (PVC) fault localization can be complicated due to the size of polishing fixture. Therefore, an alternative, relatively fast and simple method to overcome the above mentioned obstacles is proposed.

STUDY ON MICROMECHANICAL FRACTURE MODELS OF STRUCTURAL STEEL AND ITS WELDS. The Hong Kong Institute of Steel Construction, June 2021. http://dx.doi.org/10.18057/ijasc.2021.17.2.2.

Abstract:
Steel structures have been widely used in constructions due to their advantages of lightweight, high strength, short construction time and high recycling and reuse potential. Fracture failure in steel structures should be prevented to avoid collapse of the whole structures. Micromechanical fracture models can capture the fracture initiation mechanisms and therefore can be used to predict ductile fractures in steel. Twelve smooth round bars were carried out to obtain the material properties and 36 notched round bars were tested to calibrate the parameters of stress modified critical strain (SMCS) model and the void growth model (VGM) for structural steels (Q235B and Q345B) and the corresponding welds. Specimens were extracted from the base metal, the weld metal and the heat affected zone (HAZ) to investigate fracture behaviour in different parts of the welded joint. Scanning electron microscope (SEM) measurements were taken and finite element models were developed to calibrate the models. The test results and calibrated parameters are reported. Moreover, the calibrated models are applied to analyses the fracture behaviour of welded joints and their accuracy are validated. The calibrated and validated models can be used for further numerical fracture analysis in welded steel structures.
