Olfactometric pollution of air

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009
This paper describes the olfactometric assessment of volatile organic compounds emitted by coating films.It describes the measurements of concentration, intensity, hedonic tone and character of odor caused by emissions of volatile organic compounds. VOCs’

Ferroelectric Polarization Enabled Threshold Voltage Modulation in High Electron Mobility Transistor

open access: yesAdvanced Functional Materials, EarlyView.
A comprehensive model is developed to capture the coupled electrostatics of a ferroelectric capacitor and a metal‐insulator‐semiconductor high electron mobility transistor (MISHEMT) connected in ferroelectric‐metal high electron mobility transistor (FeMHEMT) configuration.

Estimating European volatile organic compound emissions using satellite observations of formaldehyde from the Ozone Monitoring Instrument [PDF]

open access: yes, 2010
Emission of non-methane Volatile Organic Compounds (VOCs) to the atmosphere stems from biogenic and human activities, and their estimation is difficult because of the many and not fully understood processes involved.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

open access: yesAdvanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Decoupling Electron and Phonon Transport in 3D‐Printed Bismuth Telluride via Synergistic Compositional Co‐Enrichment

open access: yesAdvanced Functional Materials, EarlyView.
In this work, we use direct ink writing (DIW) to 3D print Bi2Te3‐based materials and naturally induce hierarchical functional nanostructures, which reduced the lattice thermal conductivity by half, resulting in high zT of 0.87and 0.89 in p‐type and n‐type compounds, respectively, competitive with commercial materials.

Process of Formaldehyde and Volatile Organic Compounds’ Removal fromWaste Gases

open access: yesApplied Sciences, 2020
Waste gases that cannot be released into the environment are generated in chemical industrial processes. There are various physico-chemical processes for the treatment of these gases, but in most cases, they present a major cost to the company.
