Greek Protected Designation of Origin Xinomavro Wines: A Deep Dive into Their Chemical Composition and Geographical Origin by Using Ultra High Performance Liquid Chromatography–Trapped Ion Mobility Spectrometry–Quadrupole Time of Flight–Mass Spectrometry

open access: yesAnalysis &Sensing, EarlyView.
Greek protected designation of origin Xinomavro wines are analyzed with ultra high performance liquid chromatography–trapped ion mobility spectrometry–quadrupole time of flight‐mass spectrometry (UHPLC‐TIMS‐QTOF‐MS). Both target and not‐target screening approaches are employed, leading to the identification and quantification of several polyphenols and

Species traits and community properties explain species extinction effects on detritus-based food webs [PDF]

open access: yesarXiv, 2018
Effects of changes in functional composition of soil communities on nutrient cycling are still not well understood. Models simulating community dynamics overcome the technical challenges of conducting species removal experiments in the field. However, to date, available soil food web models do not adequately represent the organic matter processing ...

Calotropis procera Latex Extract as an Effective Green Corrosion Inhibitor for Mild Steel in Acidic Medium: Experimental and Quantum Chemical Approaches

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this work, Calotropis procera latex extract (CPLE) was evaluated as an environmentally benign corrosion inhibition on mild steel in 1‐M HCl using gravimetric, electrochemical, surface, and computational approaches. The results revealed that CPLE exhibited an efficient corrosion inhibitor with the efficiency of 94.26% and 93.10% at 200‐ppm ...

Environmental and Nutritional Value of Fruit and Vegetable Peels as Animal Feed: A Comprehensive Review

open access: yesAnimal Research and One Health, EarlyView.
Fruit and vegetable peels, rich in nutrients such as fiber and phenolic compounds, can boost livestock productivity, enhancing milk, meat, and draught power. Their use as animal feed reduces organic waste, cuts greenhouse gas emissions, and decreases dependence on grain‐based feeds, offering a sustainable solution with significant nutritional and ...

Toward a harmonized methodology to analyze field side effects of two pesticide products on earthworms at the EU level

open access: yesIntegrated Environmental Assessment and Management, Volume 19, Issue 1, Page 254-271, January 2023., 2023
Abstract Before plant protection product (PPP) marketing authorization, a risk assessment for nontarget soil organisms (e.g., earthworms) is required as part of Regulation (EC) No. 1107/2009. Following a stepwise approach, higher tier earthworm field studies are needed if they cannot demonstrate low long‐term risk based on laboratory studies.
