Semiconductor Gas Sensors: Materials, Technology, Design, and Application
(MDPI, Basel, 2020)
This paper presents an overview of semiconductor materials used in gas sensors, their technology, design, and application. Semiconductor materials include metal oxides, conducting polymers, carbon nanotubes, and 2D materials. ...
Superior hardness and stiffness of diamond nanoparticles
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
We introduce a computational approach to estimate the hardness and stiffness of diamond surfaces and nanoparticles by studying their elastic response to atomic nanoindentation. Results of our ab initio density functional ...
Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
(Elsevier Science Sa, Lausanne, 2020)
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A ...
Slow 0.1 Hz Breathing and Body Posture Induced Perturbations of RRI and Respiratory Signal Complexity and Cardiorespiratory Coupling
(Frontiers Media Sa, Lausanne, 2020)
Objective: We explored the physiological background of the non-linear operating mode of cardiorespiratory oscillators as the fundamental question of cardiorespiratory homeodynamics and as a prerequisite for the understanding ...
A resonant single frequency molecular detector with high sensitivity and selectivity for gas mixtures
(Nature Publishing Group, London, 2020)
Air quality control is an important task in prevention of human exposure to toxic and harmful gases and requires reliable gas sensors. During last decades many gas sensing mechanisms, based on different physical or chemical ...
Real-Time AFM and Impedance Corrosion Monitoring of Environmentally Friendly Ceria Films on AA7075
(Electrochemical Soc Inc, Pennington, 2020)
Cerium-based conversion coatings have emerged as promising green alternatives to the harmful chromium-based ones, but the mechanism of corrosive protection still remains a subject of academic and industrial research. This ...
The effects of ionizing radiation on the structure and antioxidative and metal-binding capacity of the cell wall of microalga Chlorella sorokiniana
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The impact of ionizing radiation on microorganisms such as microalgae is a topic of increasing importance for understanding the dynamics of aquatic ecosystems in response to environmental radiation, and for the development ...
Variations in polyamine conjugates in maize (Zea mays L.) seeds contaminated with aflatoxin B1: a dose-response relationship
(Wiley, Hoboken, 2020)
BACKGROUND Cereal seeds, such as maize seeds, are frequently contaminated with aflatoxin B1 (AFB1), one of the most dangerous naturally occurring carcinogens. In plants, phenolamides are involved in biotic stress response. ...
