UV-induced carbon monoxide emission from living vegetation [PDF]

Biogeosciences, 2013
The global burden of carbon monoxide (CO) is rather uncertain. In this paper we address the potential for UV-induced CO emission by living terrestrial vegetation surfaces. Real-time measurements of CO concentrations were made with a cavity-enhanced laser

ASSESSMENT OF HEAVY METALS POLLUTION IN ABIOTIC COMPONENT OF ECOSYSTEM OF VYRLYTSA LAKE

Proceedings of the National Aviation University, 2012
Abstract. The main task was to investigate the pollution by heavy metals of abiotic component in theVyrlytsa Lake. Was determined the amount of movable form of heavy metals in the water and bottomsediments by the method of atomic absorption spectroscopy.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

Advanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

ASSESSING THE RELATIVE INFLUENCES OF ABIOTIC AND BIOTIC FACTORS ON A SPECIES’ DISTRIBUTION USING PSEUDO-ABSENCE AND FUNCTIONAL TRAIT DATA: A CASE STUDY WITH THE AMERICAN EEL (Anguilla rostrata) [PDF]

, 2018
Species’ distributions are influenced by abiotic and biotic factors but direct comparison of their relative importance is difficult, particularly when working with complex, multi-species datasets. Here, we present a flexible method to compare abiotic and

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

Advanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Emerging connections between small RNAs and phytohormones [PDF]

, 2020
Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

Selective and Precise Editing of Digital Polymers Through Parallel or Series Toehold‐Mediated Strand Displacement

Advanced Functional Materials, EarlyView.
A sequence‐encoded supramolecular construct containing two accessible toeholds is developed herein for enabling multiple editing operations. By introducing specific input strands, it is possible to selectively erase or rewrite digital content through parallel or series toehold‐mediated strand displacement (PTMSD or STMSD).

Chromosome-level genomes of two Bracteacoccaceae highlight adaptations to biocrusts

Nature Communications
Biological soil crusts (biocrusts) cover the majority of the world’s dryland ground and are a significant component of the vegetation-free surface of the planet.

Storage and handling of pretreated lignocellulose affects the redox chemistry during subsequent enzymatic saccharification

Bioresources and Bioprocessing, 2020
The decomposition of lignocellulose in nature, as well as when used as feedstock in industrial settings, takes place in a dynamic system of biotic and abiotic reactions.
