Environmental Transformation and Trophic Transfer of Engineered Nanomaterials in the Agri‐Food Chain and Implications for human Health

ChemFoodChem, EarlyView.
ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Unraveling Mechanisms and Engineering Strategies for Superior Photocarrier Dynamics Toward Efficient Photocatalysis

EcoEnergy, EarlyView.
Despite its potential, photocatalysis is limited by inefficient charge carrier separation and transport. This article reviews the mechanisms, characterization methods, and strategies for improvement, concluding with future challenges in the field. ABSTRACT Photocatalysis offers a promising solution to environmental and renewable energy issues. However,

New Insights in Thylakoid Membrane Organization [PDF]

Plant and Cell Physiology, 2005
High-pressure freezing (HPF) in combination with freeze substitution (FS) was used to analyse changes in the structure of barley chloroplasts during the daily change of light and darkness. In contrast to conventional treatment of samples, HPF-FS revealed substantial differences in chloroplast shape, volume and ultrastructure in the light period and ...

Impact of tomato variety and homogenization pressure on in vitro lipid digestion and lycopene bioaccessibility in tomato emulsions

Food Biomacromolecules, EarlyView.
Tomato variety and processing impact lycopene bioaccessibility. Tomato emulsions with high pectin content decreased the in vitro lipid digestion and negatively affected lycopene bioaccessibility. High pressure homogenization may enhance the release of lycopene into emulsion oil droplets, but it may also reduce the transfer of lycopene into the micellar

Thermoluminescence in Chloroplast Thylakoid [PDF]

, 2012
Luminescence occurs in almost all the materials absorbing photon energy and is a phenomenon of light emitting process. There are various types of luminescence, e.g. fluorescence, phosphorescence, delayed luminescence, chemiluminescence and thermoluminescence.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Evolution of Thylakoid Structural Diversity

Annual Review of Cell and Developmental Biology
Oxygenic photosynthesis evolved billions of years ago, becoming Earth's main source of biologically available carbon and atmospheric oxygen. Since then, phototrophic organisms have diversified from prokaryotic cyanobacteria into several distinct clades of eukaryotic algae and plants through endosymbiosis events.

Correlation between spatial (3D) structure of pea and bean thylakoid membranes and arrangement of chlorophyll-protein complexes

BMC Plant Biology, 2012
Background The thylakoid system in plant chloroplasts is organized into two distinct domains: grana arranged in stacks of appressed membranes and non-appressed membranes consisting of stroma thylakoids and margins of granal stacks.

Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.
