In this study, zinc borate hydrate (Zn3B6O12 · 3.5H2O) was synthesized from zinc oxide (ZnO) and boric acid (H3BO3) via a novel method of ultrasonic irradiation. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) and Raman spectroscopy were used to characterize the synthesized products. Scanning…
Abstract To facilitate the utilization of graphene films in conventional semiconducting devices (e.g. transistors and memories) which includes an insulating layer such as gate dielectric, facile synthesis of bi-layers composed of a graphene film and an insulating layer by one-step thermal conversion will be very impor…
Irradiation of azomaterials causes various photophysical and photomechanical effects that can be exploited for the preparation of functional materials such as surface relief gratings (SRGs). Herein, we develop and apply an efficient strategy to optimize the SRG inscription process by decoupling, for the first time, th…
Abstract Isothermal and non‐isothermal crystallization processes of polyolefin nanocomposites based on low‐density polyethylene/linear low‐density polyethylene/nanoclay have been investigated, and the effects of nanoclay loading and dispersion state have been studied. Moreover, the isothermal crystallization of polyet…
A novel, facile, non-hazardous, low temperature/pressure microwave solvothermal method of producing pure copper, silver, and nickel metal nanofoams is presented. The nanofoams have been produced using inexpensive metal acetates and polyglycol solvent. The nanofoam formation proceeds in two steps within a single-pot sy…
Hexadecane-polyurethane core-shell nanoweb with thermo-regulating property has potential application in technical textiles such as protective clothing. However, there are challenges in preparation of hexadecane-polyurethane core-shell nanofibers due to non-conductivity of hexadecane as well as its low viscosity. The g…
Understanding why honeycombs are shaped the way they are has moved biologists, physicists, chemists, and mathematicians alike. It was only recently that the honeycombs' shape "at birth" was included in the ongoing discussions: at birth, the cells are spherical but then transform into the well-known hexagons. It was pr…
The optimization process of the desired size and quality of graphene domains is usually very difficult due to the numerous interdependent parameters in chemical vapor deposition (CVD). Here, the method so‐called “designs of experiments” is applied to estimate the relative importance and value of some of these paramete…
Fe-based shape memory alloy (Fe-SMA) shows a shape memory effect (SME) governed by forward and reverse stress-induced martensitic transformation (SIMT). Fe-SMA has been applied to joints and dampers utilized at various strain rates. To utilize Fe-SMA better, it is necessary to understand the mechanical properties in a…
SUMMARY To understand the properties of composite insulating materials, dc breakdown testing and the thermal conductivity measurement of polymethylmethacrylate (PMMA)/aluminum oxide (alumina) composite material created using the electrostatic adsorption method were performed. In the PMMA/alumina sample, which has an a…
NiTi shape memory alloy (SMA) vascular stent, with good bio-compatibility and super-elastic properties, has become an important medical device in clinical treatment of cardiovascular or cerebrovascular diseases. The free expansion of stent in vessel involves the mechanical behavior of geometric large deformation relat…
Abstract Hard magnetic SrFe 12 O 19 (SrFe) nanostructures were synthesized via a facile sol–gel procedure. The effects of temperature concentration and different capping agents on the particle size and morphology of the magnetic nanoparticles were investigated. The synthesized ferrites were characterized by X-ray diff…
An azobenzene-core chiral mesogen designed for a photoactive ferroelectric liquid crystal system with switchable polarisation displays a highly unusual phase sequence, with a re-entrant, optically isotropic, fluid phase found below smectic phases in mixtures with high enantiomeric purity. The re-entrant isotropic phas…
Background: Now a days, the multidisciplinary scientific research conception in the field of nanotechnology has witnessed development with regard to the numerous applications and synthesis of nanomaterials. Objective: The current investigation has been conducted with the main focus on the green synthesis of silver nan…
For heavily-doped semiconductor nanocrystals, a new class of plasmonic materials, the abundant dopants provide sufficient free carriers, but also act as scattering impurities, which have been limiting the merit of localized surface plasmon resonance (LSPR). To resolve this intrinsic contradiction, we propose a core-sh…
Thermochromic films with high efficiency, transparency, and flexibility are highly desirable for energy-efficient smart window films. Vanadium oxide (VO2)-nanoparticle-embedded flexible polymer composite films are the most promising thermochromic films because of the sharp phase transition of insulating to metallic ph…
mySpot is a versatile microfocussing station for scanning methods with resolution down to 1.5 µm, providing a combination of methods which can be performed simultaneously at the same sample position. It is especially designed (but not limited to) for the study of hierarchically structured biological samples. Structura…
In this work, we report that the energetic particle radiation‐resistance of ZnO can be tuned via engineering native defects. Interestingly, while we found the O i and V Zn have weak influences upon H + radiation‐resistance, the pre‐existed Zn i , and V O defects in ZnO, which are responsible for the visible band optic…
The production and properties of silver-containing products currently attract increasing attention due to the unique properties of silver. Specific properties of silver are considerably amplified when it is dispersed to the form of nanosized particles. Silver nanoparticles are several times more active than its other…
This paper investigates the flow, thermal and mechanical properties of waste polypropylene (WPP) reinforced with silica (SiO 2 ) nanoparticles (NPs). Recently the researches prove that the addition of NPs to the thermoplastic polymer produces significant change in its properties. SiO 2 NPs of 0.001, 0.003, 0.006, 0.00…
