ABSTRACT The limited efficacy of alginate as a drug carrier is thought to be due to its poor mechanical stability and durability. In the present study, cellulose/alginate (C/Alg) beads were successfully fabricated by droplet extrusion/precipitation method for drug release of metformin hydrochloride (MH). To evaluate t…
Magnetic resonance spectroscopy is one of the most important tools used across the physical and life sciences, but typically requires macroscopic samples. A key challenge is therefore to develop methods suitable for the nanometric regime. This paper investigates a new approach whereby quantum relaxation of a single ni…
Metasurfaces have powerful abilities to manipulate the properties of electromagnetic waves flexibly, especially the modulation of polarization state for both linearly polarized (LP) and circularly polarized (CP) waves. However, the transmission efficiency of cross-polarization conversion by a single-layer metasurface…
This article presents a new simple method of creating light-absorbing carbon material for optical devices such as bolometers. A simple method of laser microstructuring of graphene oxide is used in order to create such material. The absorption values of more than 98% in the visible and more than 90% in the infrared ran…
Because Bi 2 Te 3 belongs to the most important thermoelectric materials, the successful exfoliation of a single quintuple layer has opened access to an interesting two-dimensional material. For this reason, we study the thermoelectric properties of single quintuple layer Bi 2 Te 3 by considering both the electron and…
Photochromic silica nanoparticles (SiO 2 @ NPT ), fabricated through the covalent immobilization of silylated naphthopyrans (NPTs) based on 2 H -naphtho[1,2- b ]pyran ( S1, S2 ) and 3 H -naphtho[2,1- b ]pyran ( S3, S4 ) or through the direct adsorption of the parent naphthopyrans ( 1, 3 ) onto silica nanoparticles (Si…
Corrosion-protective coatings for silicate glass based on the transfer of one or two layers of graphene grown on copper by chemical vapor deposition have been demonstrated. The effectiveness of graphene to act as a glass corrosion inhibitor was evaluated by water immersion testing. After 120 days of immersion in water…
Abstract Silver nanoparticles (AgNPs) were synthesized using Pelargonium/Geranium leaf extract via a hydrothermal method. The effects of the Pelargonium/Geranium leaf extract concentration (PLEC) and the amount of 1 m m AgNO 3 solution on the center of the broad emission peak (λ max ) and the color of the synthesized…
Versatile graphene oxide putty-like material (GOP) with excellent processability is developed by mediating a graphene oxide suspension with aniline. Arbitrarily predesigned architectures on both microscopic and macroscopic scales can be molded easily. GOP cannot only be used as starting material for direct 3D printing…
Fast removal of condensates from surfaces is of great significance due to the enhanced thermal transfer coefficient and continuous condensation. However, the lost superhydrophobicity of lotus leaves intrigues us to determine what kind of surface morphologies meets the self-removal of condensates? The uphill movement o…
Gold nanoparticle– (AuNP−) protein conjugates are potentially useful in a broad array of diagnostic and therapeutic applications, but the physical basis of the simultaneous adsorption of multiple proteins onto AuNP surfaces remains poorly understood. Here, we investigate the contribution of electrostatic interactions…
We investigate the linear elastic response of amorphous solids to a shear strain at zero temperature. We find that the response is characterized by at least two distinct shear moduli. The first one, μ ZFC , is associated with the linear response of a single energy minimum. The second, μ FC , is related to sampling, th…
The hybrid supercapacitor using carbon/AlPO 4 hybrid-coated H 2 Ti 12 O 25 /activated carbon is fabricated as a cylindrical cell and investigated against electrochemical performances. The hybrid coating shows that the conductivity for the electron and Li ion is superior and it prevented active material from HF attack.…
Ti-based materials are one of the most important materials used in biomedical engineering. Recently, commercially pure (CP) Ti has attracted significant attention of research community due to its full biocompatibility with human body, and there is an ongoing demand to improve its mechanical properties without sacrific…
A family of DyX 4 M(12-MC Mn III (N)shi -4) compounds were synthesized and magnetically characterized (X = salicylate, acetate, benzoate, trimethylacetate, M = Na I or K I ). The bridging ligands were systematically varied while keeping the remainder of the MC-geometry constant. The type of monovalent cation, necessar…
Multiferroic composite materials combining ferroelectric and ferromagnetic order at room temperature have great potential for emerging applications such as four-state memories, magnetoelectric sensors, and microwave devices. In this paper, we report an effective and facile liquid phase deposition route to create multi…
Despite their various potential applications, InAs colloidal quantum dots have attracted considerably less attention than more classical II-VI materials because of their complex syntheses that require hazardous precursors. Recently, aminophosphine has been introduced as a cheap, easy-to-use and efficient phosphorus pr…
Conventional plasmonic materials, namely, noble metals, hamper the realization of practical plasmonic devices due to their intrinsic limitations, such as lack of capabilities to tune in real-time their optical properties, failure to assimilate with CMOS standards, and severe degradation at increased temperatures. Tran…
As potential photovoltaic materials, transition-metal oxides such as BiFeO3 (BFO) are capable of absorbing a substantial portion of solar light and incorporating ferroic orders into solar cells with enhanced performance. But the photovoltaic application of BFO has been hindered by low energy-conversion efficiency due…
Abstract Thermal conductivity was dramatically increased after adding natural fiber into hexagonal boron nitride (hBN)/epoxy composites. Although natural fiber does not show high-thermal conductivity itself, this study found that the synergy of natural fiber with hBN could significantly improve thermal conductivity, c…
