Recently, the discovery of vanadium-based kagome metal A V 3 Sb 5 ( = K, Rb, Cs) has attracted great interest in field superconductivity due to coexistence superconductivity, non-trivial surface state and multiple density waves. In this topical review, we present recent works unconventional waves materials . We start with charge waves, which are thought correlate time-reversal symmetry-breaking orders anomalous Hall effects Then discuss topological band structure. Next, review competition...
V-based kagome materials A V 3 Sb 5 ( = K, Rb, Cs) have attracted much attention due to their novel properties such as unconventional superconductivity, giant anomalous Hall effect, charge density wave (CDW) and pair wave. Except for the 2 a 0 × CDW (charge with in-plane superlattice modulation) in , an additional 1 4 (4 ) unidirectional stripe order has been observed at surface of RbV CsV . However, stability electronic nature remain controversial unclear. Here, by using low-temperature...

Abstract Charge accumulation at the insulator surface significantly alters electric field distribution under DC voltage and can lead to unpredictable flashover. It is realized that flashover reliant on charge approaching occurrence (CDAFO). A method of how judge moment was proposed in this study clarify charges induced flashover, whereby dynamic distributions charges, including CDAFO, were obtained from instant application The resulting analyzed with regards insulators coated SiC/epoxy, an...
In this study, a pH-responsive controlled-release mesoporous silica nanoparticle (MSN) formulation was developed. The MSNs were functionalized with histidine (His)-tagged targeting peptide (B3int) through an amide bond, and loaded anticancer drug (cisplatin (CP)) lysosomal destabilization mediator (chloroquine (CQ)). Cu2+ then used to seal the pores of via chelation His-tag. resultant nanoparticles showed release, could effectively target tumor cells effect B3int. presence CP permits...

This study aims to investigate the effect of insulation distance on charge accumulation characteristics at gas-solid interface under DC voltage. Here a plate-shaped epoxy was selected as sample, and its charging process provided by pair finger-shaped electrodes. With varying between electrodes, surface distributions were measured two cases methods. In Case 1 applied voltage level constant while in 2 average field strength unchanged. As result, for 1, hetero-charge main mode, density...
The performance of strained silicon as the channel material for transistors has plateaued. Motivated by increasing charge-carrier mobility within device to improve transistor performance, germanium (Ge) is considered an attractive option a replacement due its highest p-type in all known semiconductor materials and being compatible with today's conventional CMOS manufacturing process. However, intrinsically high carrier Ge becomes significantly degraded because Ge's native oxide unstable...
