OBJECTIVE α/β-Hydrolase domain-6 (ABHD6) is a newly identified monoacylglycerol (MAG) lipase. We recently reported that it negatively regulates glucose stimulated insulin secretion (GSIS) in the β cells by hydrolyzing lipolysis-derived MAG that acts as a metabolic coupling factor and signaling molecule via exocytotic regulator Munc13-1. Whether ABHD6 and MAG play a role in response to all class...

Abstract In this study, the effect of mesopores in Marimo nanocarbon (MNC) anode material on power generation performance a direct glucose fuel cell was investigated. Three types MNC with different mesopore distributions were used for catalyst support material; Pt as loaded metal. test, containing many pores approximately 35 nm showed highest maximum output density 0.72 mW cm−2 at 5 wt% metal l...

the present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. various methods of hydrogen production for automotive applications have been discussed first. as the hydrogen production is one of the major challenges for application of proton exchange membrane (pem) fuel cells, especially in vehicular indus...

it is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. in this paper, a cogeneration system based on solid oxide fuel cells is examined. the system, including the f...

Glucose, the major fuel in the brain, is transported across the cell membranes by facilitated diffusion mediated by glucose transporter proteins. Essentially two types of glucose transporters are localized in the membranes of brain endothelial cells, astrocytes, and neurons. Their densities are well adjusted to changes in local energy demand.

in the present study, the effect of porosity on the cathode microstructure (50:50 wt. % lsm: ysz) of a solid oxide fuel cell (sofc) has been examined. a 3-d finite element method for mixed ionic and electronic conducting cathodes (miec) is presented to study the effects of porosity on cell performance. each microstructure was realized using the monte carlo approach with the isotropic type of gr...

This work addresses the development of a compact paper-based enzymatic microfluidic glucose/O2 fuel cell that can operate using a very limited sample volume (≈35µl) and explores the energy generated by glucose at concentrations typically found in blood samples at physiological conditions (pH 7.4). Carbon paper electrodes combined with a paper sample absorption substrate all contained within a p...

In this study, a sodalite nanozeolite was synthesized and characterized by X-ray diffraction (XRD) and scanning electronic microscopy (SEM). Following the morphology evolution of the sodalite nanozeolite in the SEM images illustrates the formation of the spherical particle with a size between 60 and 80 nm. Then, carbon paste electrode (CPE) was modified by sodalite nanozeolite and Ni2+ ions. Th...

This work presents a first approach towards the development of a cost-effective enzymatic paper-based glucose/O2 microfluidic fuel cell in which fluid transport is based on capillary action. A first fuel cell configuration consists of a Y-shaped paper device with the fuel and the oxidant flowing in parallel over carbon paper electrodes modified with bioelectrocatalytic enzymes. The anode consis...
