Nanoagriculture is a viable technology by using nanomaterials under various purposes such as nano biocides, seed germination, genetic material transfer in agricultural crops. Nanoparticles were toxic to the plant, human and environment. The nanoparticles are move to the plant by various mechanisms by root uptake, cuti…
Functional garments have higher functional properties and lesser aesthetic properties. They can be workwear, active sportswear, medical wear, personal protective garments, and smart garments. The fibre contents used are mainly polyester, polyethylene, kevlar, and spandex blends which can be woven, knitted and nonwoven…
Synthesis of nanoparticles with interesting physico-chemical properties using efficient as well as eco-friendly technology is one of the main objectives of nanotechnology. Biological systems have been reported to synthesize inorganic materials under certain circumstances. Exploiting the biosynthetic potential of diffe…
Abstract The effects of thermomechanical treatment on the properties and microstructure of Cu‐Cr‐Zr alloy and Cu‐Cr‐Zr‐Ag alloy were investigated. Ag addition improves the mechanical properties of the alloy through solid solution strengthening and brings a little effect on the electrical conductivity of the alloy. A n…
High-frequency performance of graphene field-effect transistors (GFETs) with boron-nitride gate dielectrics is investigated. Devices show saturating IV characteristics and fmaxvalues as high as 34 GHz at 600-nm channel length. Bias dependence of fTand fmaxand the effect of the ambipolar channel on transconductance and…
The metalized capacitor has high energy storage density for its self-healing characteristic and is often used in pulsed power applications. The pulse life is defined as the number of charge/discharge cycles before 5% decrease in capacitance. In order to reduce the capacitance loss in the active electrode area (AEA), s…
The behavior of D retention for Fe 2+ -irradiated tungsten with a damage of 0.025–3 dpa was compared with that for neutron-irradiated tungsten with 0.025 dpa. The D 2 thermal desorption spectroscopy (TDS) spectra for Fe 2+ -irradiated tungsten consisted of two desorption stages at 450 and 550 K, while that for neutron…
Single-walled carbon nanotubes (SCWNTs) have outstanding properties that depend on structural features such as their chirality. Thus, developing a strategy to control chirality during SWCNT synthesis is critical for the exploitation of nanotube-based technologies in fields such as electronics and biomedicine. In respo…
Super fast densification behavior and the attendant corrosion features of magnesium/hydroxyapatite (Mg/HAp) bio-nanocomposites processed by high frequency induction heat sintering (HFIHS) were investigated in order to develop a new biodegradable hard tissue substituent. Mg/HAp nanocomposite with various HAp contents (…
Abstract Mithilfe von Bottom‐Up‐Verfahren können die Zusammensetzung, Größe und Form jedes beliebigen Nanokristalls gleichmäßig gesteuert werden. Die Erforschung formkontrollierter Nanokristalle hat gezeigt, dass die katalytischen Eigenschaften dieser Materialien wegen ihrer wohldefinierten Kristallflächen nicht nur v…
Combined thermal shock and steady-state heat loads (SSHLs) can have an impact on divertor materials and are therefore important for lifetime estimations and evaluations of operational thresholds of divertor components in future fusion devices such as ITER. This paper discusses the results of tests performed in the ele…
A transient molecular dynamics technique is developed to characterize the thermophysical properties of two-dimensional graphene nanoribbons (GNRs). By directly tracking the thermal-relaxation history of a GNR that is heated by a thermal impulse, we are able to determine its thermal diffusivity quickly and accurately.…
We use a single, multi-dimensional, and atomistic quantum transport simulator to investigate how far carbon nanotube, graphene nanoribbon, InGaAs, and Si ultra-thin body and nanowire n-type field-effect transistors can be scaled and to understand the mechanisms that limit their miniaturization. Despite multiple leakag…
Miniaturization to the micro and nanometer scale has been one of the most important trends in science and technology over the last several years. This trend also holds immense potential for application in the field of textile finishing. Several techniques have now become available which can be used to produce uniform…
In the presence of a small amount of a proteinous amino acid (arginine/tryptophan/histidine) or a nucleoside (adenosine/guanosine/cytidine), graphene oxide (GO) forms supramolecular stable hydrogels. These hydrogels have been characterized by field-emission scanning electron microscopy (FE-SEM), atomic force microscop…
Functional clothing represents the evolutionary segment of the technical textiles market, representing an area where clothing crosses the conventional boundaries and integrates with the domains of medicine, biotechnology, nanotechnology, physics and computing among others, to meet the multifaceted and complex requirem…
Abstract The introduction of silanes to improve processability and properties of silica-reinforced rubber compounds is critical to the successful commercial use of silica as a filler in tires and other applications. The use of silanes to promote polymer–filler interactions is expected to limit the development of a per…
Organic/inorganic hybrid nanofiber systems have generated great interest in the area of tissue engineering and drug delivery. In this study, halloysite nanotube (HNT)-doped poly(lactic-co-glycolic acid) (PLGA) composite nanofibers were fabricated via electrospinning and the influence of the incorporation of HNTs withi…
Density functional theory (DFT) studies were performed to investigate the chlorination of graphene. Unlike hydrogenation and fluorination, where the adsorption of H and F is always by covalent C–H/C–F bonding, Cl atoms generate various states when single-sided graphene exposed. In the initial reaction stage, it forms…
Abstract Two decades after the first publication on quasicrystals in aluminum manganese alloys by Shechtman et al., a “soft quasicrystal” was found in nature. Since then a number of materials successively joined the family of soft quasicrystals, including liquid crystals, polymers, nanoparticles, colloids, mesoporous…
