Potassium-ion batteries with carbon-based materials and alloy as anodes possess pronounced potassium storage cycling abilities, yet they suffer from harsh synthetic processes, low initial Coulombic efficiency, limited structure stability. Herein, we first put forward vanadium fluorophosphate (KVPO4F) a highly stable anode material for potassium-ion (PIBs). KVPO4F@C composite is successfully syn...

Development of high capacity, high-rate performance, long cycling life, and low-cost electrode materials is highly desirable for sodium-ion batteries (SIBs) potassium-ion (PIBs) to pave the way their rapid commercialization. Herein, NiP2 nanoparticles loaded in multi-shelled hollow N-doped carbon microspheres (NiP2@MHNC) are successfully prepared. The built-in heterogeneous interfaces between p...

As anodes for metal-ion batteries, metal phosphides usually suffer from severe capacity degradation because of their huge volume expansion and unstable solid electrolyte interphase (SEI), especially potassium-ion batteries (PIBs). To address these issues, this study proposes amorphous phosphates acting as buffer materials. Ten types phosphide composites embedded with in situ-formed are prepared...

Utilization of carbon dioxide (CO2) has become a crucial and anticipated solution to address environmental ecological issues. Enzymes such as carbonic anhydrase (CA) can efficiently convert CO2 into various platform chemicals under ambient conditions, which offers promising way for utilization. Herein, we constructed Pickering interfacial biocatalytic system (PIBS) stabilized by CA-embedded MOF...

The synthesis of novel 1-(2-anthryl)-1-phenylethylene (APE) di-telechelic polyisobutylenes is described. Utilization of a difunctional cationic initiator and the in situ addition of the non-homopolymerizable APE lead to the formation of di-anthryl telechelic polyisobutylenes. Products were characterized by 1H NMR spectroscopy and Size Exclusion Chromatography. The polymers were UV irradiated at...

The entomopathogenic Autographa californica (Speyer) nucleopolyhedrovirus (AcMNPV) has been genetically modified to increase its speed of kill. The potential adverse effects of a recombinant AcMNPV (AcAaIT) as well as wild type AcMNPV and wild type Spodoptera littoralis NPV (SlNPV) were studied. Cotton plants were treated with these viruses at concentrations that were adjusted to resemble the r...

When transition metal sulfides are used as high-theoretical-capacity anodes for potassium ion batteries (PIBs), their low conductivity and large volume expansion resulted in inferior rate performance cyclic stability. In this study, multifunctional graphene oxide (GO) was employed to control the diameter distribution of nanoparticles within composite fibers, which improved tensile deformation. ...

Abstract Many evolutionary relationships remain controversial despite whole-genome sequencing data. These controversies arise, in part, due to challenges associated with accurately modeling the complex phylogenetic signal coming from genomic regions experiencing distinct forces. Here, we examine how different of genome support or contradict well-established among three mammal groups using milli...

The study of the major outer membrane (OM) protein, protein I (PI), of Neisseria gonorrhoeae has proven to be as fascinating, and as frustrating, as every other aspect of this remarkable bacterium. However, intensive studies over the last few years have provided significant insight into the structure, function, and genetics of this abundant, surface-exposed porin protein. There are two forms of...
