In/ZnO bulk compounds have been synthesized using a simple solid-state process. In this study, both the structural features and thermoelectric properties of the Zn 1– x In x O series with ultralow indium content (0 ≤ x ≤ 0.02) have been studied. High-angle annular dark-field scanning transmission electron microscopy a…
Natural surface-enhanced Raman spectroscopy (SERS) chips based on plants or insects have gained increased attention due to their facile characteristics and low costs. However, such chips remain a major challenge for practical application because of poor reproducibility and stability as well as unavoidable damage to th…
Abstract Thin films of electrochromic materials such as tungsten trioxide (WO 3 ) are essential components of electrochromic devices such as “Smart Windows.” The transport of charge carriers in WO 3 thin films has been investigated intensively over the past decades, yielding a wide spread of diffusion coefficients of…
Abstract Electrodeless streamer inception on an epoxy surface under AC voltage stress was investigated for different gas compositions and pressures, with a focus on the pressure region below 1 bar. For this purpose, we used a set-up with cylindrical electrodes embedded out-of-axis in a cylindrical epoxy rod. Experimen…
Nanoparticles use in nano-biotechnology applications have increased significantly with Aminated polystyrene amine (AmPs NP), Zinc oxide (ZnO NP), and Silver (Ag NP) nanoparticles utilized in wide variety of consumer products. This has presented a number of concerns due to their increased exposure risks and associated…
Abstract A new class of core–shell magnetic gold nanocomposites is prepared in a raspberry‐like fashion by the controlled supramolecular host–guest assembly of γ‐cyclodextrins (γ‐CDs) and boron clusters. In this work, Cs 2 [ closo ‐B 12 H 12 ], a fundamental boron cluster, can play a dual role in the preparation of hi…
We use multiscale modelings to investigate the heat dissipation in 2D transistors based on phosphorene and silicene. First, molecular dynamics (MD) simulations were used to calculate the thermal interface resistance R int between the 2D materials (phosphorene and silicene) and dielectrics substrates (SiO 2 and TiO 2 )…
Polymer therapeutics (PTs) provides a potentially exciting approach for the treatment of many diseases by enhancing aqueous solubility and altering drug pharmacokinetics at both the whole organism and subcellular level leading to improved therapeutic outcomes. However, the failure of many polymer-drug conjugates in cl…
Abstract Magnesium (Mg) alloys are considered promising materials for biodegradable medical devices; however, the initial effects and distribution of released Mg 2+ ions following implantation are unclear. This is addressed in the present study, using two types of Mg alloys implanted into rats. An in vitro immersion t…
Biomaterials have been used as implants for many decades in orthopedic, plastic, ENT, and ophthalmic surgery (Table In search of an ideal soft tissue filler substance, a variety of biomaterials have been injected in form of micro particles [1] and microspheres The particles and spheres differed in chemical composition…
On the basis of their large specific surface areas, high adsorption and cation exchange capacities, swelling potential and low toxicity, natural smectite clays are attractive substrates for the gastric protection of neutral and cationic drugs. Theophylline is an amphoteric xanthine derivative that is widely used as a…
Abstract Inorganic-organic hybrid modifiers have attracted attention of scholars worldwide because they combine the advantages of both different components and provide a way for modifying the structure and properties of polymeric materials. The article describes and investigates a positive effect of reduced flammabili…
We aimed at enhancing interaction in the polyimide/sepiolite hybrid films with the loading of sepiolite in the polyimide matrix ranged from 0 to 8 wt% via acid activating and polydopamine doping. First, sepiolite was treated with a 3M HCl solution under reflux conditions. Then the acid‐activated sepiolite was coated b…
Conductive rubber nanocomposites were prepared by dispersing conductive nanotubes (CNT) in thermoreversibly cross-linked ethylene propylene rubbers grafted with furan groups (EPM-g-furan) rubbers. Their features were studied with a strong focus on conductive and mechanical properties relevant for strain-sensor applica…
A tensile test was conducted to investigate the mechanical properties of hybrid bio-composites that have potential for application in helmet shells. Helmets can protect users from serious injuries, reducing traumas and deaths. Military helmets are made with 19 layers of Kevlar, and bicycle helmets are made of glass fi…
There is a continuous change in cell wall composition and organization during cotton fiber development. Cotton fiber strength correlates to the molecular weight (MW) and molecular weight distribution (MWD), and organization of cellulose chains in the secondary cell wall. These parameters change drastically during fibe…
ABSTRACT Nonvolatile and nonhazardous acrylated epoxidized soybean oil (AESO) was investigated as a replacement for hazardous styrene in a commercial unsaturated polyester (UPE) resin [a mixture of styrene and a dicyclopentadiene (DCPD)‐modified UPE (DCPD–UPE)]. DCPD–UPE was prepared from ethylene glycol, diethylene g…
Long-term hydrothermal aging of polyamide 6 (PA6)/glass fibre (GF) composites was conducted and the effects of the GF on variations of structure and properties of the composites with aging time were investigated. It was found that the first stage of aging was a Fickian process and corresponded to the physical absorpti…
In this work, MoS 2 /VO 2 hybrids were synthesized using a two-step hydrothermal method. We used tungsten doping to stabilize the VO 2 into the rutile phase at room temperature. The VO 2 surface was treated using sulfuric acid to enhance the growth sites for MoS 2 as well as the hydrogen evolution reaction active site…
