larvae or young adults inhibits TOR and other known longevity genes and induces an extended health span in a normal-lived Ra strain adult. Combining larval curcumin feeding with an adult dietary restriction (DR) diet does not yield an additive effect. The age-specific mortality rate is decreased and is comparable with…
Reactive ion etching of RbTiOPO4(0 0 1) substrates and (Yb,Nb):RbTiOPO4/RbTiOPO4(0 0 1) epitaxial layers has been performed using fluorine chemistry. A maximum etch rate of 8.7 nm/min was obtained, and the deepest etch achieved was 3.5 μm. The (Yb,Nb)-doped epitaxial layers showed a slower etching rate when compared w…
The synthesis of a bowl-shaped trinuclear circular titanium-based helicate is reported. The strategy allowing access to this neutral architecture is based on a multicomponent self-assembly approach in which the ligands involved in the process are a bis-biphenol strand and 2,2'- bipyrimidine. By reacting the bis-biphen…
Methodologies for the synthesis of size selective monodisperse AuCu intermetallic nanoparticles have been provided.
Widespread application of a neural network has been obvious in many fields of chemical engineering over the last years. The thermal conductivity of liquids has been predicted by using this kind of network and compared with experimental outcomes. Heat transfer of fluids is important in many industrial sectors, includin…
We introduce a functional for simulating ground-state and time-dependent electronic systems within density-functional theory. The functional combines an expression for the exact Kohn-Sham (KS) potential in the limit of complete electron localization with a measure of the actual localization. We find accurate self-cons…
Purpose: To evaluate the antidiarrhea and antioxidant properties of honokiol extracted from Magnoliae officinalis cortex (bark of Magnolia officinalis), an important medical material in traditional Chinese medicine, for treating diseases such as diarrhea and thrombotic stroke.Methods: The antidiarrhea activity of hono…
Well-dispersed α-Fe2O3 nanostructures with controlled dimensionality and shape have been successfully prepared via a facile and environmentally friendly solvothermal route with the assistance of 1-N-butyl-3-methylimidazolium benzoate ([Bmim][PhCOO]). A significant advancement has been made in tailoring dendritic α-Fe2…
A direct synthesis of 4,8-functionalized benzo[1,2- b :4,5- b ′]difurans was developed for organic electronics, with a power conversion efficiency 4.61% for polymer solar cells.
We demonstrated herein the facile synthesis of triisopropylsilylethynyl (TIPS) functionalized benzo[1,2- b :4,5- b ′]dithiophene (BDT) for efficient polymer solar cells.
A new three-dimensional porous metal-organic framework, JUC-119, constructed by a pyrene-based dendritic organic linker, H8TIAPy (H8TIAPy = 1,3,6,8-tetrakis(3,5-isophthalic acid)pyrene), and Eu(III) has been synthesized successfully. JUC-119 shows unexpected stability under a wide range of basic conditions from 0 to 0…
Chiral monolithic absorbent is successfully constructed for the first time by using optically active helical-substituted polyacetylene and graphene oxide (GO). The preparative strategy is facile and straightforward, in which chiral-substituted acetylene monomer (Ma), cross-linker (Mb), and alkynylated GO (Mc) undergo…
The formation of sheaths near metallic or dielectric-coated wall materials in contact with a plasma is ubiquitous, often giving rise to physical phenomena (sputtering, secondary electron emission, etc) which influence plasma properties and dynamics both near and far from the material interface. In this paper, we use f…
A modeling‐based approach is presented to understand physically realistic and technologically interesting material properties and operating configurations of packed‐bed membrane reactors (PBMRs) for propane dehydrogenation (PDH). PBMRs composed of microporous or mesoporous membranes combined with a PDH catalyst are co…
Development of unique nanoheterostructures consisting of indium oxide nanoclusters like species doped on the TiO2 nanocrystals surfaces with {101} and {001} exposed facets, resulted in unprecedented sacrificial hydrogen production (5.3 mmol h(-1) g(-1)) from water using methanol as a sacrificial agent, under visible l…
Although charged side chains play important roles in protein function, their dynamic properties are not well understood. Nuclear magnetic resonance methods for investigating the dynamics of lysine side-chain NH3(+) groups were established recently. Using this methodology, we have studied the temperature dependence of…
Scratches at the surface of fused silica optics can be detrimental for the performance of optical systems. A carbon dioxide (CO2) laser is an interesting tool to remove those scratches because it can melt efficiently the silica in a rapid and localized way, without generating debris. In this article, we propose a new…
A strategy to site-selectively monoacylate an antitumor saponin OSW-1 was developed using an organotin reagent to rapidly access its derivatives that are useful as chemical probes. 4″-O-Acylated OSW-1 derivatives bearing a fluorophore, an alkyne tag, or biotin were prepared in good yields and were shown to maintain hi…
The doping sequence in the sol–gel process plays an important role in determining the visible light photocatalytic activity of nonmetal-doped TiO 2 .
We report a computational study of water and small alcohols on coordinatively unsaturated sites in the Cu–BTC metal–organic framework using Monte Carlo simulations. Binding energies and characteristic distances with copper centers are in agreement with these obtained from experiments and theoretical methods revealing…
