TL;DR: In this paper, the results indicated that 99.06% of vanadium was extracted and only 7.95% of aluminum was co-extracted in a counter-current extraction comprising five stages under the optimal conditions.

TL;DR: In this article, perforated plates with various blockage ratios are seated at the beginning of the detonation propagation to explore the diffractions generated from the plates on the explosion propagation mechanism, and two explosive mixtures of C2H2 + 5N2O and C2 H2 + 2.5O2 + 70% Ar are studied to illustrate the difference in propagation velocity behavior of detonation after it suffers from large-scale diffractions.

TL;DR: This work developed the first nickel-catalyzed direct ortho-thiolation of N-benzoyl α-amino acid derivatives, which showed wide generality, functional tolerance, and high regioselectivity.
Abstract: We developed the first nickel-catalyzed direct ortho-thiolation of N-benzoyl α-amino acid derivatives. This novel strategy showed wide generality, functional tolerance, and high regioselectivity. In addition, dipeptide derivatives were also compatible with this transformation system, providing a potential protocol for the direct modification of peptide derivatives.

TL;DR: In this article, the authors reported the chemical pre-intercalation of a small amount of calcium ions into V2O5 as the cathode material, which achieved a high specific capacity of 400 mA h g−1 at the current density of 0.05 A g− 1 and 187 mAA h g −1 at 10 A g − 1, along with impressive capacity retention.
Abstract: Rechargeable aqueous zinc ion batteries (ZIBs), with the easy operation, cost effectiveness, and high safety, are emerging candidates for high-energy wearable/portable energy storage systems. Unfortunately, the unsatisfactory energy density and undesired long-term cycling performance of the cathode hinder the development of ZIBs. Here, we report the chemical pre-intercalation of a small amount of calcium ions into V2O5 as the cathode material. The cathode of Ca0.04V2O5•1.74H2O (CVO) was demonstrated to have a high specific capacity of 400 mA h g−1 at the current density of 0.05 A g−1 and 187 mA h g−1 at 10 A g−1, along with impressive capacity retention (100% capacity retention at 10 A g−1 for 3,000 cycles). Meanwhile, the CVO// Zn battery exhibits a high energy density of 308 Wh kg−1 and a power density of 467 W kg−1 at 0.5 A g−1. The superior performance originates from the pinning effect of the calcium ions and the lubricating effect of the structural water. The energy storage mechanism of the CVO cathode was also investigated in detail. The new phase (Zn3(OH)2V2O7•2H2O) generated upon cycling participates in the electrochemical reaction and thus contributes to the excellent electrochemical performance. The small amount of Ca2+ pre-inserted into the interlayer of V2O5 sheds light on constructing cathodes with high energy density for ZIBs.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: This Review describes how the tunable electronic structure of TMDs makes them attractive for a variety of applications, as well as electrically active materials in opto-electronics.
Abstract: Ultrathin two-dimensional nanosheets of layered transition metal dichalcogenides (TMDs) are fundamentally and technologically intriguing. In contrast to the graphene sheet, they are chemically versatile. Mono- or few-layered TMDs - obtained either through exfoliation of bulk materials or bottom-up syntheses - are direct-gap semiconductors whose bandgap energy, as well as carrier type (n- or p-type), varies between compounds depending on their composition, structure and dimensionality. In this Review, we describe how the tunable electronic structure of TMDs makes them attractive for a variety of applications. They have been investigated as chemically active electrocatalysts for hydrogen evolution and hydrosulfurization, as well as electrically active materials in opto-electronics. Their morphologies and properties are also useful for energy storage applications such as electrodes for Li-ion batteries and supercapacitors.
