Carbon materials, including graphite, hard carbon, soft graphene, and carbon nanotubes, are widely used as high-performance negative electrodes for sodium-ion potassium-ion batteries (SIBs PIBs). Compared with other materials abundant, low-cost, environmentally friendly, have excellent electrochemical properties, which make them especially suitable electrode of SIBs PIBs. traditional modificati...

Carbonaceous materials are attractive anode candidates for potassium-ion batteries (PIBs) because of their cost-effectiveness, high conductivity, and considerable architecture. However, these carbon usually exhibit slow diffusion kinetics huge volume variation induced by the large ionic size K-ions, resulting in poor rate capability cycling stability. Compared to pure carbon, heteroatom (N, S, ...

Owing to the cost-effectiveness, Earth abundance, and suitable redox potential, potassium-ion batteries (PIBs) stand out as one of best candidates for large-scale energy storage systems. However, large radius K+ unsatisfied specific capacity are main challenges their commercial applications. To address these challenges, constructing heterostructures by selecting integrating 2D materials host ot...

Polyisobutylenes (PIBs) with different end-groups including chlorine, exo-olefin, hydroxyl and methyl initiated from aliphatic and aromatic initiator were studied by electrospray ionization mass spectrometry (ESI-MS). Independently of the end-groups, presence or absence of aromatic initiator moiety, these PIB derivatives were capable of forming adduct ions with NO3 and Cl ions, and thus allowin...

Abstract Potassium‐ion batteries (PIBs) are considered promising alternatives to lithium‐ion owing cost‐effective potassium resources and a suitable redox potential of −2.93 V (vs. −3.04 for Li + /Li). However, the exploration appropriate electrode materials with correct size reversibly accommodating large K ions presents significant challenge. In addition, reaction mechanisms origins enhanced ...

In the face of hybridization, species integrity can only be maintained through post-zygotic isolating barriers (PIBs). PIBs need not only be intrinsic (i.e. hybrid inviability and sterility caused by developmental incompatibilities), but also can be extrinsic due to the hybrid's intermediate phenotype falling between the parental niches. For example, in migratory species, hybrid fitness might b...

Sodium-ion batteries (SIBs) and potassium-ion (PIBs) are prospective candidates for large-scale energy storage systems cause of their abundant resources. However, unsatisfactory rate cycling performance carbon-based anodes present a bottleneck the applications SIBs/PIBs due to large sizes sodium/potassium ions. Herein, oxygen-doped vertically aligned carbon aerogels (VCAs) with hierarchically t...

The poor electronic conductivity and large volume expansion effect of MoS2 limit its application in potassium-ion batteries (PIBs). In addition to exploring effective modification methods, it is also necessary build a new self-standing electrode system improve energy density. this work, based on the potassium storage advantages disadvantages carbon nanofibers, we have successfully prepared soft...

Insect cells are natural hosts for baculoviruses. Following infection, nuclear polyhedral inclusion bodies (PIBs) and budded virus (BV) are produced. Virion-rich PIBs are ingested by insect larvae as food contaminants. Upon PIB digestion in the insect midgut, virions replicate in midgut cells and spread to other tissues, leading larvae to become a fluid-filled sac containing large amounts of ne...
