Рассмотрены возможности использования наноструктур станната цинка в качестве чувствительных элементов газовых сенсоров с высоким быстродействием, которые представляют большой интерес для самых разных областях применения от обнаружения токсичных веществ до мониторинга качества воздуха или медицинской диагностики. Синтез проводили при гидротермальной обработке наностержней растворе калия и мочеви...

Abstract Pressure reduction following uplift may lead to dissociation of gas hydrates. The dynamics hydrate in such settings, however, are poorly understood. We used TOUGH+HYDRATE investigate the response hydrates an 0.009 myr $$^{-1}$$ - 1 </mml...

We study a Fermi gas with strong, tunable interactions dispersively coupled to high-finesse cavity. Upon probing the system along cavity axis, we observe strong optomechanical Kerr nonlinearity originating from density response of intracavity field and measure it as function interaction strength. find that zero-frequency increases by factor two Bardeen-Cooper-Schrieffer Bose-Einstein condensate...

We analyze the linear response properties of uniformly heated granular gas. The intensity stochastic driving fixes value temperature in nonequilibrium steady state reached by system. Here, we investigate two specific situations. First, look into ``direct'' relaxation system after a single (small) jump intensity. This study is carried out different methods. Not only do linearize evolution equati...

Despite tremendous potential and urgent demand in high-response low-cost gas identification, the development of gas identification based on a metal oxide semiconductor nanowire/nanobelt remains limited by fabrication complexity and redundant signals. Researchers have shown a multisensor-array strategy with "one key to one lock" configuration. Here, we describe a new strategy to create high-resp...

Response of highly sensitive SnO2 semiconductor carbon monoxide (CO) gas sensors based on target gas CO quasi-molecular-imprinting mechanism design is investigated with gas concentrations varied from 50 to 3000 ppm. SnO2 nanoparticles prepared via hydrothermal method and gas sensor film devices SC (exposed to the target gas CO for 12 h after the suspension coating of SnO2 film to be fully dried...
