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

Abiotic formation of O2 and O3 in high-CO2 terrestrial atmospheres [PDF]
Astron.Astrophys.472:665-679,2007, 2007 Previous research has indicated that high amounts of ozone (O3) and oxygen (O2) may be produced abiotically in atmospheres with high concentrations of CO2. The abiotic production of these two gases, which are also characteristic of photosynthetic life processes, could pose a potential "false-positive" for remote-sensing detection of life on planets ...

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.

Titania may produce abiotic oxygen atmospheres on habitable exoplanets [PDF]
Scientific Reports 5, Article number: 13977 (2015), 2015 The search for habitable exoplanets in the Universe is actively ongoing in the field of astronomy. The biggest future milestone is to determine whether life exists on such habitable exoplanets. In that context, oxygen in the atmosphere has been considered strong evidence for the presence of photosynthetic organisms.

Plants, 2018 Abiotic stress remains one of the major challenges in managing and preventing crop loss. Photosystem II (PSII), being the most susceptible component of the photosynthetic machinery, has been studied in great detail over many years.

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.

Redox evolution via gravitational differentiation on low mass planets: implications for abiotic oxygen, water loss and habitability [PDF]
The Astronomical Journal, 155:195 (25pp), 2018 May, 2017 The oxidation of rocky planet surfaces and atmospheres, which arises from the twin forces of stellar nucleosynthesis and gravitational differentiation, is a universal process of key importance to habitability and exoplanet biosignature detection. Here we take a generalized approach to this phenomenon.

Probiotic‐Based Mineralized Living Materials to Produce Antimicrobial Yogurts
Advanced Healthcare Materials, EarlyView.The self‐assembly and mineralization of collagen in the presence of probiotics produces hybrid living materials that hosts and protects the cells. Intra‐ and interfibrillar mineralization of collagen fibers, as occurring in bone, results, respectively, in a bulk and single‐cell protective layer of cells, that survive in simulated gastric conditions and,
