High photoluminescent (PL) nitrogen-doped carbon dots (N-CDs) have been synthesized using ferric ammonium citrate (FAC) and urea as raw materials by simple one-pot hydrothermal process. The N-CDs possess bright blue fluorescence (centred at 450 nm; 36.2% quantum yield) and green fluorescence (centred at 530 nm; 47.6% quantum yield) only by adjusting the excitation wavelength from 310 nm to 510 nm. The N-CDs exhibited high N content of 32.81 wt%, low cytotoxicity, and good PL stability at different pH ...

The thermodynamically unfavorable anaerobic dehydrogenative alcohol activation to aldehydes and hydridometal species is found to be the bottleneck in metal-catalyzed N-alkylations due to a general and unnoticed catalyst deactivation by amines/amides. Thus, different from the anaerobic dehydrogenation process in borrowing hydrogen or hydrogen autotransfer reactions that require noble metal complexes or addition of capricious ligands for catalyst activation, the water-producing, exothermic, metal- ...

3,17β-Hydroxysteroid dehydrogenases (3,17β-HSDs) are found in all forms of life which catalyze the 3-position and 17-position reduction/oxidation of steroids. Comamonas testosteroni (C. testosteroni) ATCC11996 is a gram-negative bacterium which can use steroids as carbon and energy source. 3,17β-HSD is an enzyme which is involved in the complete oxidative degradation of the steroid skeleton, induced in the presence of these compounds in the culture medium.

An electrochemiluminescence (ECL)-based method for rapid and sensitive detection of acridinium ester in neutral solution was described. Strong ECL emission was observed when a positive voltage over 2.0 V (versus Ag/AgCl) was applied to the working electrode (Pt) immersed in the acridinium ester solution of 2.0 mol l−1 KNO3 (pH 7.0). The possible ECL mechanism was discussed. It was proposed that the ECL emission came out of N-methylacridone, the oxidization product of acridinium ester by the nascent ...

The electrogenerated chemiluminescence (ECL) behavior of N-(4-aminobutyl)-N-ethylisoluminol (ABEI) was studied and it was found that ABEI could produce emission light when oxidized at a +1.0 V (vs. Ag/AgCl) potential in alkaline solution. The addition of H2O2 markedly improved the ECL sensitivity. The pH value of the solution as well as the H2O2 concentration and working potential all have influences on the ECL response. Under optimal conditions, ABEI can be detected in the range 1.3 × 10−6–6.5 × 10−12 ...

C. testosteroni is a research topic that can degrade steroid hormones into water and carbon dioxide through a series of enzymes in the body. Short-chain dehydrogenase (SDR) are a class of NAD (P) H-dependent oxidoreductases in C. testosteroni. Its main function is catalyzing the redox of the hydroxyl/ketone group of the hormone. In this paper, a SDR gene(SDRx) is cloned from C. testosteroni ATCC11996 and expressed. The polyclonal antibody was prepared and the SDRx gene knocked out by homologous recombination. ...

Phase change material (PCM) cooling is a prominent approach for battery thermal management. However, its application scenario is severely limited by the narrow range of phase change temperature. When the temperature of PCM does not reach the phase change temperature range, it is either a pure thermal conductive material or a completely molten liquid material, neither of which can play a role in battery thermal management. The present study proposes a novel petal-type battery thermal management system ( ...

Traditional state estimation (SE) methods are usually implemented in a centralized way. The increased size, complexity of power systems, and the deregulation of the power industries result in the inefficiency of the conventional SE methods. Thus, improved SE solutions in terms of computational speed, easy implementation, and flexibility are urgently needed for future power systems. In this paper, a fully distributed integrated solution is proposed for multiarea topology identification (TI) and SE ...

Because of the uncertainties and highly time-varying, it is not easy to accurately obtain the complete information for the consumer behavior in electricity grid. In this case, the Q-learning, which is independent of mathematic model, and prior-knowledge, has good performance. The fuzzy inference and Metropolis Criterion ...

Abstract The crystallization behavior of polylactic acid (PLA) was studied in the presence of a crystal nucleating agent, ethylenebishydroxystearamide (EBH). The crystallization rate and crystallinity were significantly increased with addition of EBH. The isothermal crystallization half‐time at 105°C was decreased from 18.8 minutes for neat PLA to 2.8 minutes for PLA with 1.0 wt % of EBH. The crystallinity of PLA with 1.0 wt % EBH was about 35% after 5‐minute annealing at 105°C. Like neat PLA, the double ...

A series of Sm- and/or Zr-doped MnOx-TiO2 catalysts were prepared, and the catalysts exhibited better N2 selectivity and SO2 resistance than the undoped MnOx-TiO2 catalyst for the selective catalytic reduction of NO by NH3 (NH3-SCR). The reasons for the good N2 selectivity and SO2 resistance of the catalysts were proposed. X-ray photoelectron spectroscopy (XPS) combined with density functional theory (DFT) calculations suggested that electron transfer between the manganese and samarium species by Mn4+ + ...
