The van der Waals (vdW) heterostructures have rich functions and intriguing physical properties, which has attracted wide attention. Effective control of excitons in vdW is still urgent for fundamental research realistic applications. Here, we successfully achieved quantitative tuning the intralayer exciton monolayers observed transition from to interlayer WS2/MoSe2 heterostructures, via hydrostatic pressure. energy a “locked” or “superstable” state, not sensitive first-principles...
Ribonucleic acids (RNA) play active roles within cells or viruses by catalyzing biological reactions, controlling gene expression, and communicating responses to cellular signals. Rapid monitoring RNA variation has become extremely important for appropriate clinical decisions frontier research. However, the most widely used method detection, nucleic acid amplification, is restricted a mandatory temperature cycling period of ≈1 h required reach target detection criteria. Herein, direct...
Abstract The coupling between electrons and phonons is ubiquitous in condensed matter physics. In recent years, with the rise of two dimensional (2D) materials, electron–phonon interaction exhibits unique characteristics compared their three‐dimensional counterparts. this paper, research progress 2D materials briefly reviewed, mainly focus on thermoelectric device, conventional superconductor, field effect transistor, photoelectric device. Firstly, application concluded according to reports,...
Efficient hot electron extraction is a promising approach to develop photovoltaic devices that exceed the Shockley-Queisser limit. However, experimental evidence of harvesting employing an organic-inorganic interface still elusive. Here, we reveal dynamics at CuPc/MoSe2 using steady-state spectroscopy and transient absorption spectroscopy. A transfer efficiency greater than 78% from MoSe2 CuPc observed, comparable achieved in quantum dot hybrid systems. The mechanism proposed as follows:...

Biogenetic biosilica displays intricate patterns that are structured on a nanometer-to-micrometer scale. At the nanoscale, it involves polymerization products of silica, apparently mediated by interaction between different biomolecules with special functional groups. In this paper, using tetraethyl orthosilicate [TEOS, Si(OCH2CH3)4] as silica source, phospholipid (PL) and dodecylamine (DA) were introduced model organic additives to investigate their influence formation morphology in...
