With the development of nanotechnology and the wide use of graphene, it has become necessary to assess the potential biological adverse effects of graphene. However, most of the recent publications are focused on various modified graphenes. We demonstrated biological effects of commercial pristine graphene in murine RAW 264.7 macrophages, which is an(More)
Light-emitting diodes (LEDs) are excellent candidates for general lighting because of their rapidly improving efficiency, durability, and reliability, their usability in products of various sizes, and their environmentally friendly constituents. Effective lighting devices can be realized by combining one or more phosphor materials with chips. Accordingly,(More)
Plasmonic photocatalysis has recently facilitated the rapid progress in enhancing photocatalytic efficiency under visible light irradiation, increasing the prospect of using sunlight for environmental and energy applications such as wastewater treatment, water splitting and carbon dioxide reduction. Plasmonic photocatalysis makes use of noble metal(More)
Instead of developing a novel red phosphor individually, this work proposes the production of white light by combining a near-ultraviolet/ultraviolet diode chip with blue and special yellow phosphors: the yellow phosphor includes the red and green components with high color saturation. The availability of this scheme is demonstrated by preparing a white(More)
The present investigation aims at the synthesis of (Y2-xEuxBiy)O3 red phosphor materials using the combinatorial chemistry method. We developed square-type arrays consisting of 90 compositions to obtain the optimum composition of co-dopants in a Y2O3 host. The optimized composition was found to be (Y2-xEuxBiy)O3 (x = 0.16-0.18, y = 0.08-0.10). The screening(More)
The hepatitis E virus (HEV) capsid consists of a single structural protein, a portion of which is engaged in isosahedral contact to form a basal shell, and another portion in dimeric contact to form the homodimers protruding from the shell. Previous studies revealed that homodimers of the truncated HEV capsid proteins, E2 (amino acids 394-606) and p239(More)
With the advancements in nanotechnology, studies on the synthesis, modification, application, and toxicology evaluation of nanomaterials are gaining increased attention. In particular, the applications of nanomaterials in biological systems are attracting considerable interest because of their unique, tunable, and versatile physicochemical properties.(More)
We identified potassium channel tetramerization domain-containing 1 (KCTD1) gene in a human brain cDNA library. Here, we report that the KCTD1 gene contains seven exons, encoding 257 amino acid residues with a predicted molecular mass of 29.4 kDa. Sequence alignments showed KCTD1 protein contains an N-terminal broad-complex, tramtrack, and bric-a-brac (BTB)(More)
White light-emitting diodes (WLEDs) have matched the emission efficiency of florescent lights and will rapidly spread as light source for homes and offices in the next 5 to 10 years. WLEDs provide a light element having a semiconductor light emitting layer (blue or near-ultraviolet (nUV) LEDs) and photoluminescence phosphors. These solid-state LED lamps,(More)
This review concerns the efficient conversion of sunlight into chemical fuels through the photoelectrochemical splitting of water, which has the potential to generate sustainable hydrogen fuel. In this review, we discuss various photoelectrode materials and relative design strategies with their associated fabrication for solar water splitting. Factors(More)
