Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation

Angewandte Chemie, EarlyView.
Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...

Climatic and Anthropogenic Impacts on ´13C Variations in a Stalagmite from Central China

Terrestrial, Atmospheric and Oceanic Sciences, 2013
In this paper, we present a δ13C record that covers the past 750 years at a resolution of 2 - 3 years which was preserved in a precisely dated stalagmite (DY-1) obtained from the Dayu Cave on the south flank of the Qinling Mountains in central China ...

COMPARATIVE QUALITATIVE AND QUANTITATIVE ANALYSIS OF THE TERSKO SULAKSKAY LOWLAND'S AREAS

Вестник Дагестанского государственного технического университета: Технические науки, 2016
Data are obtained in the comparative analysis of cartographic materials on the Tersko-Sulaksky lowland (50-2000 years). In comparison with fifties the increase in extent of salinization of soils and their area more than twice is revealed, reduction of ...

Integrated Bipolar Membrane Electrodialysis and Electrolysis for CO2 Capture and Conversion

Advanced Energy Materials, EarlyView.
This work demonstrates an integrated BMEED platform that couples CO2 capture and conversion within a single modular system. By combining BMED with CO2E, high‐purity CO is produced while avoiding intermediate stripping, excessive capital and O&M costs, and external gas feeds.

Micromorphological and Chemical Features of Soils as Evidence of Bronze Age Ancient Anthropogenic Impact (Late Bronze Age Muradymovo Settlement, Ural Region, Russia)

Geosciences, 2018
In some cases, the human impact on ancient landscapes has been so profound that local soils still remain significantly affected even after hundreds and thousands of years after ending impact.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Heavy Metal Contamination: Impacts From Plants to the Food Chain and Eco‐Friendly Amelioration Strategies

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

Resolving passive heat transfer and phase‐change heat in cryogenic CO2 deposition (Desublimation) from CO2/N2 mixtures

AIChE Journal, EarlyView.
Abstract In cryogenic CO2 desublimation systems where phase change dominates both heat transfer and separation, conventional lumped thermal‐resistance treatments embed interfacial latent heat into an overall heat‐transfer coefficient, obscuring how phase‐change heat is partitioned between the gas phase and the coolant and limiting diagnostic insight ...
