The artificial photosynthesis technology known as the Honda-Fujishima effect, which produces oxygen and hydrogen or organic energy from sunlight, water, and carbon dioxide, is an effective energy and environmental technology. The key component for the higher efficiency of this reaction system is the anode electrode, generally composed of a photocatalyst formed on a glass substrate from electrically conductive fluorine-doped tin oxide (FTO). To obtain a highly efficient electrode, a dense film composed of a nanoparticulate visible light responsive photocatalyst that usually has a complicated multi-element composition needs to be deposited and adhered onto the FTO...

The effect of a thin α-Fe2O3 compact buffer layer (BL) on the photoelectrochemical performances of a bare α-Fe2O3 nanorods photoanode is investigated. The BL is prepared through a simple spray deposition onto a fluorine-doped tin oxide (FTO) conducting glass substrate before the growth of a α-Fe2O3 nanorods via a hydrothermal process. Insertion of the hematite BL between the FTO and the nanorods markedly enhances the generated photocurrent, by limiting undesired losses of photogenerated charges at the FTO||electrolyte interface...

Using inexpensive and environmentally friendly Mn oxide, a very simple method to synthesize an efficient and stable water-oxidizing electrode on the surface of a fluorine doped tin oxide electrode was reported. The electrode at pH = 13 yields a current density of 1 mA cm(-2) at an overpotential of 450 mV, which is promising to be used as an anode in water-splitting systems. In higher overpotential (800 mV), a current density of 7 mA cm(-2) was observed. Proposed different states of the growth of layered Mn oxide on the surface of FTO based on SEM images were also discussed...

Lower olefins-generally referring to ethylene, propylene and butylene-are basic carbon-based building blocks that are widely used in the chemical industry, and are traditionally produced through thermal or catalytic cracking of a range of hydrocarbon feedstocks, such as naphtha, gas oil, condensates and light alkanes. With the rapid depletion of the limited petroleum reserves that serve as the source of these hydrocarbons, there is an urgent need for processes that can produce lower olefins from alternative feedstocks...

Cupric oxide (CuO), a narrow-bandgap semiconductor, has a band alignment that makes it an ideal photocathode for the renewable production of solar fuels. However, the photoelectrochemical performance of CuO is limited by its poor conductivity and short electron diffusion lengths. Herein, a three-dimensional (3D) architecture consisting of CuO nanosheets supported onto transparent conducting macroporous antimony-doped tin oxide (mpATO@CuONSs) is designed as an excellent photocathode for promoting the hydrogen evolution reaction (HER)...

OBJECTIVE: A major barrier to genetic studies of OA is the need to obtain large numbers of individuals with standardized radiographic evaluations for OA. To address this gap, we performed a genome-wide association study (GWAS) of radiographically-defined tibiofemoral knee OA in 3,898 cases and 3,168 controls from four well-characterized North American cohorts, and replication analysis of published OA loci. METHODS: We performed meta-analysis using a two-stage design...

Excitation energy transfer in monomeric and trimeric forms of photosystem I (PSI) from the cyanobacterium Synechocystis sp. PCC 6803 in solution or immobilized on FTO conducting glass was compared using time-resolved fluorescence. Deposition of PSI on glass preserves bi-exponential excitation decay of ~4-7 and ~21-25 ps lifetimes characteristic of PSI in solution. The faster phase was assigned in part to photochemical quenching (charge separation) of excited bulk chlorophylls and in part to energy transfer from bulk to low-energy (red) chlorophylls...

INTRODUCTION: Obesity is a chronic, complex, and multifactorial disease, characterized by excess body fat. Diverse studies of the human genome have led to the identification of susceptibility genes that contribute to obesity. However, relatively few studies have addressed specifically the association between the level of expression of these genes and obesity. MATERIAL AND METHODS: We studied 160 healthy and obese unrelated Mexican children aged 6 to 14 years. We measured the transcriptional expression of 20 genes associated with obesity, in addition to the biochemical parameters, in peripheral white blood cells...

Organic-inorganic lead perovskite materials show impressive performance in photovoltaics, photodetectors, light-emitting diodes, lasers, sensors, medical imaging devices, and other applications. Although organic-inorganic lead perovskites have shown good performance in numerous fields, they contain toxic Pb, which is expected to cause environmental pollution in future large-scale applications. Thus, the photoelectric properties of Pb-free organic-inorganic perovskite materials should be developed and studied...

A compact-layer-free, hole-conductor-free, fully printable mesoscopic perovskite solar cell presents a power conversion efficiency of over 13%, which is comparable to that of the device with a TiO2 compact layer. The different wettability of the perovskite precursor solution on the surface of FTO and TiO2 possesses a significant effect on realizing efficient mesoscopic perovskite solar cell. This result shows a promising future in printable solar cells by further simplifying the fabrication process and lowering the preparation costs...

Water oxidation on visible-light-active bismuth vanadate (BiVO4) has commonly been demonstrated to be viable in powder suspension (PS) and particulate photoelectrochemical (PEC) systems. Here, we demonstrate that particle size reduction, which is known to be efficacious in promoting charge carrier extraction and boosting surface active sites, has an opposite effect on BiVO4's photoactivity in the two systems. With three BiVO4 samples of distinctive particle sizes, smaller BiVO4 particle size is shown to be beneficial for enhancing PEC photocurrent generation, but deleterious for photocatalytic O2 evolution on suspended BiVO4...

It is a key challenge to conduct reproducibility in genetic research, especially association studies in obesity. While susceptibility of a single-nucleotide polymorphism (SNP), rs9939609, in the fat mass and obesity-associated (FTO) gene to obesity has been reported in various populations, data from Asians is less conclusive. This replication study was carried out to test whether the FTO rs9939609 SNP is a predictive factor for obesity and obesity-related metabolic traits in a Taiwanese population. A total of 1188 Taiwanese subjects were recruited for this study...

Non-alcoholic steatohepatitis (NASH) is one of the most common causes of liver failure worldwide. It is characterized by excess fat accumulation, inflammation, and increased lipotoxicity in hepatocytes. Currently, there are limited treatment options for NASH due to lack of understanding of its molecular etiology. In the present study, we demonstrate that the expression of fat mass and obesity associated gene (FTO) is significantly increased in the livers of NASH patients and in a rodent model of NASH. Furthermore, using human hepatic cells, we show that genetic silencing of FTO protects against palmitate-induced oxidative stress, mitochondrial dysfunction, ER stress, and apoptosis in vitro...

Fat mass and obesity-associated (FTO) protein contributes to non-syndromic human obesity which refers to excessive fat accumulation in human body and results in health risk. FTO protein has become a promising target for anti-obesity medicines as there is an immense need for the rational design of potent inhibitors to treat obesity. In our study, a new scaffold N-phenyl-1H-indol-2-amine was selected as a base for FTO protein inhibitors by applying scaffold hopping approach. Using this novel scaffold, different derivatives were designed by extending scaffold structure with potential functional groups...
