Satellite assessment of winter cover crop and conservation tillage outcomes to support adaptive management in working landscapes

Journal of Environmental Quality, EarlyView.
Abstract The use of winter cover crops and conservation tillage are agricultural practices promoted to reduce nutrient and sediment loss from cropland, improve soil health, increase infiltration, and support farm nutrient cycling and ecosystem services. However, environmental performance of these practices is variable in the working farm landscape. The

SYNTHESIS AND INVESTIGATION OF THIN TiO₂ FILMS, DOPED WITH COPPER NANOPARTICLES

Вестник Северо-Кавказского федерального университета, 2022
Thin films of titanium dioxide, doped with copper nanoparticles, were synthesized by the method of deposition on the rotating substrate. The obtained films were dried at room temperature and at temperature of TiO2 calcination and studied by ellipsometry,

Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA)

, 2017
When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-

The ICOS OTC pCO2 instrument intercomparison

Limnology and Oceanography: Methods, EarlyView.
Abstract In 2021, the Ocean Thematic Centre of the European Research Infrastructure “Integrated Carbon Observation System” conducted an international partial pressure of carbon dioxide (pCO2) instrument intercomparison. The goal was to understand how different types of instrumentation for the measurement of ocean pCO2 compare to each other.

Synthesis of Cellulose Hexanoate, Benzoate, and Mixed Esters: Exploring Their Potential as Enzyme Immobilization Platforms

Macromolecular Bioscience, EarlyView.
Cellulose sourced from cotton linters was utilized to synthesize cellulose esters, specifically hexanoate, benzoate, and a mixed hexanoate‐benzoate variant, which were evaluated as platforms for enzyme immobilization. These esters were shaped into various architectural forms, including electrospun mats, layered sandwich structures, and spherical shapes.

SYNTHESIS OF ETHYL FATTY ALKYL ETHERS FROM COCONUT (Cocos nucifera L.) FATTY ALCOHOLS

Annals of Tropical Research, 1987
Ethyl fatty alkyl ethers were synthesized using coconut fatty alcohols as the starting raw materials. The fatty alcohols were converted into their corresponding bromides which were then made to react with ethanolic potassium hydroxide.

Redox Active Polyaniline‐Chitosan Supported Nano Silver Composites with Tunable Surface Structure and Catalytic Activity

Macromolecular Chemistry and Physics, EarlyView.
This study elaborates on the structure‐function role of (bio)polymer supports on the catalytic activity of polyaniline‐chitosan nanocomposites (NCs) that contain Ag nanoparticles (Ag@PNI‐(x)‐CHT). These NCs can be tailored to enhance selectivity in reductive transformations of model dyes: methylene blue (MB) and p‐nitrophenol (PNP).
