It has been suggested that the role of compatible solutes in plant stress responses is not limited to conventional osmotic adjustment, but also includes some other regulatory or osmoprotective functions. In this study, we hypothesized that one such function is in maintaining cytosolic K+ homeostasis by preventing NaCl-induced K+ leakage from the cell, a feature that may confer salt tolerance in...

Memristor (memory resistor) is a passive electrical circuit element whose instantaneous resistance depends not only on the voltage, but the history of the current applied to it. The first memristor was fabricated in 2008 by the HP labs in a semiconductor titanium-dioxide thin film. Apart from its potential for high-density memory storage, the electrical properties of a memristor share similarit...

Channelrhodopsin (ChR) is a light-gated cation channel that responds to blue light. Since ChR can be readily expressed in specific neurons to precisely control their activities by light, it has become a powerful tool in neuroscience. Although the recently solved crystal structure of a chimeric ChR, C1C2, provided the structural basis for ChR, our understanding of the molecular mechanism of ChR ...

We show that a semiconductor membrane made of two thin layers of opposite (n- and p-) doping can perform electrically tunable ion current rectification and filtering in a nanopore. Our model is based on the solution of the 3D Poisson equation for the electrostatic potential in a double-cone nanopore combined with a transport model. It predicts that, for appropriate biasing of the membrane-elect...

We show that a semiconductor membrane made of two thin layers of opposite (nand p-) doping can perform electrically tunable ion current rectification and filtering in a nanopore. Our model is based on the solution of the 3D Poisson equation for the electrostatic potential in a double-cone nanopore, combined with a transport model. It predicts that for appropriate biasing of the membraneelectrol...

This paper presents the impact of parameter optimization of n-type MOSFET for direct tunneling gate current using ultrathin Si3N4 and HfO2 with EOT (Equivalent Oxide Thickness) of 1.0 nm. This work is compared with TCAD santaurus simulation results to verify that accuracy of the model and excellent reduction in gate leakage with the introduction of the high-k gate dielectrics (HfO2 & Si3N4) in ...

This study investigated the effects of accidental contamination soils with phenol, toluene, nitric acid, and hydrogen fluoride (HF) by simulating chemical leakage in soil with/without rain characterizing resulting metabolites microbial. In case acid leakage, pH cation exchange capacity were decreased, content ion was increased HF leakage. Using mass spectrometry-based metabolomics analysis, phy...

Impacts of source/drain (S/D) recess engineering on the device performance both gate-all-around (GAA) nanosheet (NS) field-effect transistor (FET) and FinFET have been comprehensively studied at 5 nm node technology. TCAD simulation results show that off-leakage, including subthreshold leakage through channel (Isub) punch-through (IPT) in sub-channel, is strongly related to S/D process. Firstly...
