The construction of anode materials for alkali-ion batteries with high capacity and a long life span is significant remains challenging. With the increasing interest in vanadium sulfide, V3S4 possesses unique structure shows great promise application batteries, such as lithium-ion (LIBs), sodium-ion (SIBs), potassium-ion (PIBs). However, it still faces problems large volume changes low electron...

Potassium-ion batteries (PIBs) are of academic and economic significance, but still limited by the lack highly active electrode materials for de-/intercalation large-radius K ions. Herein, an interconnected nitrogen/sulfur co-doped carbon nanosheep bundle (N/S-CSB) was proposed as potassium ions storage material. The rich co-doping N/S-CNB with three-dimensional hierarchical bundled array struc...

Uma das regiões brasileiras mais contempladas com o Programa de Aquisição Alimentos (PAA) é Nordeste, onde se localiza Maranhão, objeto estudo deste trabalho. Diante sua relevância, pretende-se identificar número municípios maranhenses que receberam recursos do PAA e os valores recebidos durante período 2010 a 2018 mediante análise tabular gráfica, como também verificar efeitos no PIB total nos...

This research was carried out to examine cytopathological effects of Helicoverpa armigera Cytoplasmic polyhedrosis virus (HaCPV) on infected midgut cotton bollworm (Helicoverpa armigera) using transmission and scanning electron microscope. The symptoms on infected host larvae of the host, compared with healthy ones, were getting swollen with milky-white and fragile Histopathological examination...

Este trabalho analisa a influência do comércio exterior nas microrregiões Espírito Santo. Para tanto, além de uma comparação entre o capixaba e brasileiro, são avaliados os desempenhos das dez Estado. São comparados comportamentos dos fluxos comerciais – somas exportações com as importações PIBs regionais, seus coeficientes abertura. identificados principais setores produtos envolvidos essas co...

Most potassium-ion battery (PIB) cathode materials have deficient structural stability because of the huge radius potassium ion, leading to inferior cycling performance. We report controllable synthesis a novel low-strain phosphate material K3(VO)(HV2O3)(PO4)2(HPO4) (denoted KVP) nanorulers as an efficient for PIBs. The as-synthesized KVP nanoruler exhibits initial reversible capacity 80.6 mAh ...

In this study, 6 lepidopteran cell lines derived from Trichoplusia ni (Tn5), Lymantria dispar (LdElta), Bombyx mori (Bm-5), Spodoptera frugiperda (Sf21), Spodoptera exigua (Se-1), and Choristoneura fumiferana (Cf-124T) were investigated for susceptibility to Malacosoma neustria nucleopolyhedrovirus (ManeNPV) isolated in Turkey. Infection of Malacosoma disstria (Md203) cell line by ManeNPV was u...

We discuss the calculationof the width difference APB. between the Bs mass eigen-states to next-to-leading order in the heavy quark expansion. l/rat,-corrections are estimated to reduce the leading order result by typically 30%. The error of the present estimate (Al?/P),, = O.lS~ " ,:$ could be substantially improved by pinning down the value of (B,~(~~~~)s-P(~~s~)s-PIB~) and an accuracy of 10%...

Heteroatom doping, especially nitrogen has been regarded as an efficient strategy to break through the capacity limitation of carbonaceous anode materials in potassium-ion batteries (PIBs). Constructing edge-nitrogen-rich carbon skeleton with highly exposed active sites and charge transfer is critical for high performance nitrogen-doped materials. Herein, a kind ultrahigh edge-nitrogen (up 16.2...

Sodium- and potassium-ion batteries have exhibited great application potential in grid-scale energy storage due to the abundant natural resources of Na K. Conversion-alloying anodes with high theoretical capacity low-operating voltage are ideal option for SIBs PIBs but suffer tremendous volume variations. Herein, a hierarchically structural design sp2 N-doping assist conversion-alloying materia...
