The broadband light-absorption ability of carbon dots (CDs) has inspired their application in photocatalysis, however this has been impeded by poor electron transfer inside the CDs. Herein, we report the preparation of Cu-N-doped CDs (Cu-CDs) and investigate both the doping-promoted electron transfer and the performan…
The co-doping of graphene with nitrogen and sulfur was investigated aiming at understanding their interactions with the presence of oxygen in graphene. The co-doped graphene (NS-G) was synthesized via a one-pot hydrothermal route using graphene oxide as starting material and L-cysteine, an amino acid containing both N…
The surface properties and adsorption mechanisms of graphene materials are important for potential environmental applications. The adsorption of m-dinitrobenzene, nitrobenzene, and p-nitrotoluene onto graphene oxide (GO), reduced graphene oxide (RGO), and graphene (G) nanosheets was investigated using IR spectroscopy…
Recently, food packages produced with nanoparticles, "nano-food packaging," have become more available in the current market. However, although the use of nanomaterials is increasing in food packaging applications, concern over toxicity affects consumer perceptions and acceptance. Quite a number of commercialized form…
Two-dimensional layered semiconductors such as molybdenum disulfide (MoS2) have attracted tremendous interest as a new class of electronic materials. However, there are considerable challenges in making reliable contacts to these atomically thin materials. Here we present a new strategy by using graphene as the back e…
The porous three-dimensional (3-D) flower structures assembled by numerous ultrathin flakes were favor for strengthen electromagnetic absorption capability. However, it still remains a big challenge to fabricate such kind of materials. In this study, an easy and flexible two-step method consisting of hydrothermal and…
Natural hydrogels are promising scaffolds to engineer epidermis. Currently, natural hydrogels used to support epidermal regeneration are mainly collagen- or gelatin-based, which mimic the natural dermal extracellular matrix but often suffer from insufficient and uncontrollable mechanical and degradation properties. In…
JPred4 (http://www.compbio.dundee.ac.uk/jpred4) is the latest version of the popular JPred protein secondary structure prediction server which provides predictions by the JNet algorithm, one of the most accurate methods for secondary structure prediction. In addition to protein secondary structure, JPred also makes pr…
Layer-by-layer (L-b-L) assembly is a simple method that is useful in immobilizing nanomaterials into thin films. However, the retention of the optical and photogalvanic property of the nanoparticles and the functionalization of these materials are the common issues raised regarding this technique. In this study, L-b-L…
The 14k, 45k, and 70k Mw PCL have different crystallization temperatures and therefore have slightly different characteristics affecting the fiber diameter. To observe these behaviors, the fiber was produced at every step of <TEX>$10^{\circ}C$</TEX> for each molecular weights and the diameter was measured. Moreover, t…
Grafting efciency, grafting proportion, and grafting frequency determine water absorbability [1,2], cation exchange property [3], dyeability with the basic dyes, and the degree of compatibility of lignocellulose natural bers with a polymer matrix [4]. The products can be used as superabsorbents, ion exchange composite…
Effects of current density on nanostructure and light emitting properties of porous silicon (PS) samples were investigated by field emission scanning electron microscope (FE-SEM), gravimetric method, Raman and photoluminescence (PL) spectroscopy. FE-SEM images have shown that below 60 mA/cm 2 , macropore and mesopore…
One of the promising material for proton-conducting solid electrolyte operating at intermediate temperature range (400-600 °C) is the Yttrium-doped BaZrO 3 (BZY) due to its high conductivity and chemical stability. In this study, a modified citrate-nitrate combustion method (Pechini method) has been employed for BZY p…
ABSTRACT This article describes a methodology to prepare polyurethanes (PUs), decorated with pendant (bio)functional side groups, by polymerizing (bio)functionalized blocked diisocyanates with polyols. Caprolactam blocked lysine diisocyanate methyl ester (BLDI‐OMe) was prepared in high yields, by reacting the methyl e…
In this study, we describe two new Halamphora species (Halamphora subfontinalis and H. hezhangii) and identify three species newly recorded in China (H. elongata, H. submontana and H. tenella) and two others previously recorded from China (H. montana and H. dusenii), as well as make preliminary observations on three i…
A second-moment, tight-binding charge equilibration (SMTB-Q) model for the atomic interactions in TiO 2 is refined by comparison with results of density functional theory (DFT) calculations within the generalized gradient approximation and used to study the atomic structure of the ⟨11̅1⟩ step on the rutile (110) surfa…
Rare-earth-doped BaCeO 3 and BaZrO 3 electrolytes with perovskite structure have been studied extensively in developing proton conducting intermediate temperature SOFC. Acceptor doped alkaline earth cerates and zirconates have been thoroughly studied because of the great interest in their possible applications as soli…
Rare-earth permanent magnetic nanoflakes and nanoparticles have drawn great attention due to their potential applications in fabricating permanent magnets with high performance. In this work, the anisotropic PrCo5 nanoflakes were fabricated via surfactant-assisted ball milling at low temperature and room temperature,…
Idealized glass transitions are discussed within an alternative mode-coupling theory (TMCT) proposed by Tokuyama [Physica A 395, 31 (2014)]. This is done in order to identify common ground with and differences from the conventional mode-coupling theory (MCT). It is proven that both theories imply the same scaling laws…
Objective: Potential of novel hydroxyl terminated dendrimer generations G1(OH) 8 , G2(OH) 32 and G3(OH) 128 as solubility enhancers of model drug ketoprofen was evaluated. G3(OH) 128 dendrimer was further explored as the novel carrier for sustained release of ketoprofen. Cytotoxicity and hemolytic potential of G3(OH)…
