Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

EFFICIENCY OF PHOTOSYNTHETIC APPARATUS OF PLANTS GROWN IN SITES DIFFERING IN LEVEL OF PARTICULATE MATTER

Acta Scientiarum Polonorum: Hortorum Cultus, 2014
Particulate matter (PM) is among the most harmful pollutants inhaled by man. To reduce its concentration in air, plants could be used as biological filters, adsorbing PM on the foliage (SPM) or stabilizing in waxes (WPM).

Sustainable plant‐leaf‐derived carbon dots with deep‐red emission enable 1‐min photodynamic therapy of tumors

FlexMat, EarlyView.
In this study, plant‐derived carbon dots (CDs) were prepared using natural plant leaves as raw materials through solvothermal method. These CDs retain the porphyrin structure from chlorophyll and can simultaneously generate I and II types of reactive oxygen species. A 660 nm laser irradiation for only 1 min can achieve efficient photodynamic anti‐tumor

Monitoring photosynthesis in individual cells of Synechocytis sp. PCC 6803 on a picosecond timescale [PDF]

, 2010
Picosecond fluorescence kinetics of wild-type (WT) and mutant cells of Synechocystis sp. PCC 6803, were studied at the ensemble level with a streak-camera and at the cell level using fluorescence-lifetime-imaging microscopy (FLIM).

Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products

Food Safety and Health, EarlyView.
Growing global demand for safe fish preservation has increased interest in natural alternatives. Seaweed‐derived bioactive compounds possess antioxidant and antimicrobial properties that enhance fish quality, safety, and shelf life. These sustainable preservatives may reduce spoilage and synthetic preservative use, though further research ...

Nitrogen‐doped graphene quantum dots tune the mineral, acid, and sugar profile of raisins in a cultivar‐specific manner

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Carbon dots are emerging as low‐toxicity nano‐biostimulants, but their effects on the integrated mineral, organic‐acid, and sugar profiles of grape berries remain poorly characterized, especially in indigenous Vitis vinifera L. cultivars.

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

Limnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.
