Abstract:

Metallic materials engineered at the nanoscale demonstrate strength levels up to three times higher compared to traditional commercial crystalline alloys. This remarkable enhancement stems from recent advancements in nanostructure design strategies, which have revolutionized how we approach material engineering. Due to their unique characteristics, nanomaterials exhibit exceptional chemical reactivity and mechanical properties that their conventional counterparts simply cannot match. These advantages arise from carefully controlled grain sizes and the development of heterogeneous nanostructure

Solar energy is a green and sustainable clean energy source. Its rational use can alleviate the energy crisis and environmental pollution. Directly converting solar energy into heat energy is the most efficient method among all solar conversion strategies. Recently, various environmental and energy applications based on nanostructured photothermal materials stimulated the re-examination of the interfacial solar energy conversion process. The design of photothermal nanomaterials is demonstrated to be critical to promote the solar-to-heat energy conversion and the following physical and chemical

Abstract:

Nanostructured materials remarkably improve the overall properties of thermoelectric devices, mainly due to the increase in the surface-to-volume ratio. This behavior is attributed to an increased number of scattered phonons at the interfaces and boundaries of the nanostructures. Among many other materials, nanostructured Si was used to expand the power generation compared to bulk crystalline Si, which leads to a reduction in thermal conductivity. However, the use of nanostructured Si leads to a reduction in the electrical conductivity due to the formation of low dimensional features in the he

To mitigate carbon emission from the combustion of fossil fuels, membrane is advantageous due to the fact that membrane is a thin interphase acting as a selective barrier separating two phases.

Abstract:

Pump-probe photoinduced birefringence measurements were carried out in amorphous and in nanostructured sol–gel films with Disperse Red 1 (DR1) azochromophores embedded in a SiO2 matrix. X-ray diffraction (XRD) patterns determine the long-range nanostructure order of the films, exhibiting a lamellar nanostructure, with two different d-spacings, due to the presence during the sol–gel process of the Sodium Dodecyl Sulfate (SDS) or of the Cetyltrimethylammonium Bromide (CTAB) ionic surfactants. The photoinduced birefringence measurements were performed on fresh and on heat treated films as a funct

Abstract:

Surfactant-templated synthesis of ordered nanostructured materials attracts more and more attention. In this paper, ordered nanostructured Fe3O4powder was synthesized via a facile reflux method in ethanol-water media using sodium dodecyl sulphonate (SDS, C12H25SO3Na) as template. XRD and VSM were used to characterize the ordered nanostructure, inorganic phase and magnetic properties. Results show that Fe3O4powder is of an ordered nanostructure of 7.6 nm which was detected by SAXRD and the inorganic phase is composed of cubic Fe3O4nanocrystals. VSM analysis shows that the ordered nanostructured

Abstract:

There has been much recent interest in heat transport in nanostructures, and alsoin the structure, properties, and growth of biological materials. Here we present measurements of thermal properties of a nanostructured biomineral, ivory. The room-temperature thermal conductivity of ivory is anomalously low in comparison with its constituent components. Low-temperature (2–300 K) measurements ofthermal conductivity and heat capacity reveal a glass-like temperature dependenceof the thermal conductivity and phonon mean free path, consistent with increased phonon-boundary scattering associated with

Abstract:

Grafting aptamers on nanostructured substrates has shown ultrasensitivity in isolation of circulating tumor cells (CTCs). Here, we report that over 80 cm2of homogenous nanostructured surface on glass substrates can be prepared in 5 min after one-step dry etching. The surface area was doubled; the average diameter of nanostructures is approximately 374 nm, which is more close to the nanostructures of natural extracellular matrix. Antiepithelial cell adhesion molecule aptamers grafted nanostructured glass substrates captured over 76% of PC3 cells compared to 30% of planar substrates. Bispecific

Abstract:

Despite their interesting properties, nanostructured materials have found limited use as a result of the cost of preparation and the difficulty in scaling up. Herein, the authors report a technique, friction stir processing (FSP), to refine grain sizes to a nanoscale. Nanocrystalline 7075 Al with an average grain size of 100 nm was successfully obtained using FSP. It may be possible to further control the microstructure of the processed material by changing the processing parameters and the cooling rate. In principle, by applying multiple overlapping passes, it should be possible to produce an

Abstract:

Nanostructured polymers constitute an increasingly important class of materials. Investigations into the formation of nanostructural elements in microphase-ordered block copolymers have elucidated universal mechanisms of self-organization in soft-condensed matter, since topologically comparable nanostructures develop in biological and surfactant systems. Emerging applications of such polymers include nanotemplates for inorganic materials, optical switches and nanoreactors. Despite all the efforts that have focused on these materials in previous years, basic questions regarding the characterist

Flame vapor deposition (FVD) process can be used to prepare the tungsten oxide thin film which has photocatalytic activity at visible light. The FVD process is fast and economical to prepare thin film on substrate comparing to other processes. Various nanostructured thin films could be easily prepared by controlling several process parameters in FVD. One-dimensional (1-D) nanostructures with high surface area also can be prepared reproducibly. The tungsten wire precursor was oxidized and vaporized in flame to be deposited onto the substrate.

Fabrication of one-dimensional nanostructures is a key issue for optical devices, fluidic devices, and solar cells because of their unique functionalities such as antireflection and superhydrophobicity. Here, we report a novel one-step process to fabricate patternable hierarchical structures consisting of microstructures and one-dimensional nanostructures using a sacrificial layer. The layer plays a role as not only a micromask for producing microstructures but also as a nanomask for nanostructures according to the etching time. Using this method, we fabricated patterned hierarchical structure
