Making of a single solid-state nanopore on the wall of fused silica capillary [PDF]

open access: yesRoyal Society Open Science, 2018
A channel of nanometre size is an important platform for nanofluidic investigations. In this work, we show that a single solid nanopore can be generated by hydrogen fluoride etching of the outside wall of commercially available fused silica capillary ...

A low-voltage activated, transient calcium current is responsible for the time-dependent depolarizing inward rectification of rat neocortical neurons in vitro [PDF]

open access: yes, 1987
Intracellular recordings were obtained from rat neocortical neurons in vitro. The current-voltage-relationship of the neuronal membrane was investigated using current- and single-electrode-voltage-clamp techniques.

Deep Homography for License Plate Detection

open access: yesInformation, 2020
The orientation of plate images in license plate recognition is one of the factors that influence its accuracy. In particular, tilted plate images are harder to detect and recognize characters with than aligned ones.

INCREASING THE EFFECTIVENESS OF STABILIZATION COLUMNS IN THE OIL AND GAS INDUSTRY

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2018
According to the results of the study, we found that increasing the pressure in a stabilization column improves the sharpness of separation of butanes from pentanes. As a result, the product quality is getting better.

Directed transport of a deformable particle in confined periodic structures

open access: yesNew Journal of Physics, 2022
Directed transport of a deformable particle is numerically investigated in a two-dimensional periodic channel. Unlike the rigid particle, the deformable particle can pass through the channel bottleneck that is significantly smaller than the particle size.

SELECTING THE OPTIMUM SCHEME OF THE SEPARATION OF HYDROCARBON GASES BY DISTILLATION

open access: yesТонкие химические технологии, 2018
The heat costs in distillation columns were determined for the purpose of separating a four-component gas mixture in gas fractionators with various component selection sequences. A method for selecting the optimal scheme was developed. It is based on the
