A facile and efficient approach to preparing alumina/Cu composite microspheres with silver-decorated polydopamine coating is proposed.
Biomedical applications ranging from tissue engineering to drug delivery systems require versatile biomaterials based on the scalable and tunable production of biopolymer nanofibers under physiological conditions. These requirements can be successfully met by a novel extrusion process through nanoporous aluminum oxide…
Graphene nanoplatelets (Gnps) were covalently functionalized by 3-aminopropyltriethoxysilane (KH550) and noncovalently functionalized by Triton X-100, respectively. The morphology and structure of KH550 modified graphene (K-Gnp) and Triton X-100 modified graphene (T-Gnp) were characterized by Fourier transform infrare…
Lanthanide ion doped upconversion nanoparticles (UCNPs) are known to be able to convert long-wavelength excitation light (usually 980 nm) into high-energy ultraviolet (UV) or visible emissions, and they have attracted significant attention because of their distinct photochemical properties including sharp emission ban…
Clay minerals are widely used in pharmaceutical formulations, therefore studying how they interaction with proteins is important because they can alter their biological functions.
Sustained release of anti-inflammatory agents remains challenging for small molecule drugs due to their low molecular weight and hydrophobicity. Therefore, the goal of this study was to control the release of a small molecule anti-inflammatory agent, crystal violet (CV), from hydrogels fabricated with heparin, a highl…
Water, when constrained between two graphene sheets and under ultrahigh pressure, can manifest dramatic differences from its bulk counterparts such as the van der Waals pressure induced water-to-ice transformation, known as the metastability limit of two-dimensional (2D) liquid. Here, we present result of a new crysta…
The electronic and optical properties of a hydrogenated/fluorinated SiC heterobilayer were systematically investigated by using density functional theory calculations.
To achieve a device application of the quantum spin Hall (QSH) effect, increasing the critical temperature is crucial. A two-dimensional topological insulator (2D-TI) with a sizeable bulk band gap is one of the most promising strategies to reach this goal. Using first-principles calculations, we propose a new 2D-TI, t…
In this work, we investigated the effects of chemical substitution on the structural, electronic, and optical properties of α-Ag2-2xNixWO4 (0 ≤ x ≤ 0.08) solid solutions prepared by a facile microwave-assisted hydrothermal method. The results showed that the increase of Ni concentration in α-Ag2WO4 microcrystals as a…
Tuning the electronic properties of graphene by doping atoms into its lattice makes it more applicable for electronic devices.
In situ embedding of sensitive materials (e.g., cells and proteins) in silk fibers without damage presents a significant challenge due to the lack of mild and efficient methods. Here, we report the development of a microfluidic chip-based method for preparation of meter-long silk fibroin (SF) hydrogel fibers by mimick…
Although Group II-VI quantum dots (QDs) have attracted much attention due to their wide range of applications in QD-based devices, the presence of toxic ions in II-VI QDs raises environmental concerns. To fulfill the demands of nontoxic QDs, synthetic routes for III-V QDs have been developed. However, only a few compa…
In this contribution, we have developed a simple, environmentally friendly fluorescent turn-off sensor for the detection of copper (Cu 2+ ) ions in aqueous solution by using lysozyme stabilized gold nanoclusters (Lys-AuNCs) as a fluorescent probe.
A new bioartificial polymeric material consisting of a bilayer of cellulose acetate and poly(vinyl alcohol) was successfully obtained by casting method. The material was characterized by Fourier transform infrared spectroscopy, contact angle, scanning electron microscopy, differential scanning calorimetry, gas permeab…
Clustering of OH groups over graphene basal plane stabilizes the interaction with alkali metal ions, preventing irreversible reduction, while the charge is stored in OH groups interacting with ions and the π electronic system.
The possibility of developing new advanced optical limiters of laser radiation at 532 nm with low limiting thresholds has been demonstrated on thermally stable phthalocyanine J-type dimeric complexes of Mg, Zn, Cu, Ni, and Co. A new "threshold" model based on radiative transfer phenomena in nonlinear optical media was…
Varied morphologies and aspect ratios of magnetic Janus rods have been synthesized via a wet-chemical method.
We have investigated a series of Pt–TiO 2 and Pt–CeO 2 catalysts for crotonaldehyde hydrogenation with the goal of better understanding the kinetics of CO bond hydrogenation.
–COOH functionalized poly(vinylidene fluoride) prepared using water-based non-fluorinated solvents displays tunable wettability suitable for potential application in coating, oil recovery and water purification.
