Study on Consistency of Diagnostic Ratios of Different Oils
Using GC/MS analysis means, distribution of n-alkanes, PAHs, and biomarkers and consistency of diagnostic ratios of different kinds of oil were studied. The results indicate that: (1) Some diagnostic ratios of different oils are not obviously different and may even be consistent. These diagnostic ratios include two n-alkanes diagnostic ratios ((C19+C20)/(C19~C22) and CPI), four terpanes diag…

Leveraging Heterogeneous Power for Improving Datacenter Efficiency and Resili…
Power mismatching between supply and demand has emerged as a top issue in modern datacenters that are under-provisioned or powered by intermittent power supplies. Recent proposals are primarily limited to leveraging uninterruptible power supplies (UPS) to handle power mismatching, and there fore lack the capability of efficiently handling the irregular peak power mismatches. In this paper we p…

In Vivo Repeatedly Charging Near-Infrared-Emitting Mesoporous SiO 2 /ZnGa 2 O…
Near-infrared (NIR) persistent phosphor ZnGa 2 O 4 :Cr 3+ (ZGC) has unique deep-tissue rechargeable afterglow properties. However, the current synthesis leads to agglomerated products with irregular morphologies and wide size distributions. Herein, we report on in vivo rechargeable mesoporous SiO 2 /ZnGa 2 O 4 :Cr 3+ (mZGC) afterglow NIR-emitting nanocomposites that are made by a simple, one-s…

Background and Aims: According to the floral ABC model, B-function genes appear to play a key role in the origin and diversification of the perianth during the evolution of angiosperms. The basal angiosperm Hedyosmum orientale (Chloranthaceae) has unisexual inflorescences associated with a seemingly primitive reproductive morphology and a reduced perianth structure in female flowers. The aim …

Abstract The selective hydrogenation of trans-4-phenyl-3-butene-2-one over Ru/g-Al2O3 stabilized with triphenylphosphine was investigated in the presence of diamine and base. It was found that 1,2-diphenylethylene-1,2-diamine (DPEN) was the best modifier among the investigated diamines. Both DPEN and KOH not only promoted the selectivity of the C O bond hydrogenation, but also accelerated the …

Synthesis of Biodiesel via Acid Catalysis
Biodiesel is synthesized via the transesterification of lipid feedstocks with low molecular weight alcohols. Currently, alkaline bases are used to catalyze the reaction. These catalysts require anhydrous conditions and feedstocks with low levels of free fatty acids (FFAs). Inexpensive feedstocks containing high levels of FFAs cannot be directly used with the base catalysts currently employe…

ABSTRACT Electronic memory devices having the indium-tin oxide/polymer/Al sandwich structure were fabricated from polymers containing pendant azobenzene chromophores in donor-acceptor structures. The reversibility, or rewritability, of the high-conductivity (ON) state was found to be dependant on the terminal moiety of the azobenzene chromophore. While the polymers with electronaccepting term…

Background In response to high salt intake, transcription factor hypoxia-inducible factor (HIF) 1α activates many antihypertensive genes, such as heme oxygenase 1 (HO-1) 1 and cyclooxygenase 2 (COX-2) in the renal medulla, which is an important molecular adaptation to promote extra sodium excretion. We recently showed that high salt inhibited the expression of HIF prolyl-hydroxylase 2 (PHD2)…
