Description

Application

Foliar applied potassium nanoparticles (K-NPs) and potassium sulfate on growth, physiological, and phytochemical parameters in Melissa officinalis L. under salt stress.: This investigation assesses the effectiveness of potassium sulfate in alleviating salt stress in plants, focusing on its role in enhancing growth and stress tolerance. The study provides valuable data for improving crop resilience to salinity, a growing issue in global agriculture (Nanehkaran FM et al., 2024).

Effects of Potassium-Containing Fertilizers on Sugar and Organic Acid Metabolism in Grape Fruits.: Examining the role of potassium sulfate in grapevine nutrition, this research elucidates its impact on the metabolic pathways involved in sugar and organic acid production. The outcomes are significant for viticulture, offering strategies to enhance fruit quality and vine health (Wang J et al., 2024).

The combination of chemical fertilizer affected the control efficacy against root-knot nematode and environmental behavior of abamectin in soil.: This study investigates how potassium sulfate, when used in conjunction with other fertilizers, influences the efficacy of pesticides and the soil′s environmental dynamics. The findings are crucial for developing integrated pest management strategies that are environmentally sustainable (Jiang J et al., 2024).

Efficient photoelectrochemical hydrogen production from bismuth vanadate-decorated tungsten trioxide helix nanostructures.

Xinjian Shi et al.

Nature communications, 5, 4775-4775 (2014-09-03)

Tungsten trioxide/bismuth vanadate heterojunction is one of the best pairs for solar water splitting, but its photocurrent densities are insufficient. Here we investigate the advantages of using helical nanostructures in photoelectrochemical solar water splitting. A helical tungsten trioxide array is

Division and Adaptation to Host Environment of Apicomplexan Parasites Depend on Apicoplast Lipid Metabolic Plasticity and Host Organelle Remodeling.

Souad Amiar et al.

Cell reports, 30(11), 3778-3792 (2020-03-19)

Apicomplexan parasites are unicellular eukaryotic pathogens that must obtain and combine lipids from both host cell scavenging and de novo synthesis to maintain parasite propagation and survival within their human host. Major questions on the role and regulation of each

Lipase-coated K2SO4 micro-crystals: preparation, characterization, and application in biodiesel production using various oil feedstocks.

Jingjing Zheng et al.

Bioresource technology, 110, 224-231 (2012-02-15)

This study investigated the preparation and characteristics of protein-coated microcrystals (PCMCs) from Pseudomonas cepacia lipase (PS) and K(2)SO(4), and their application in biodiesel synthesis, via single factorial experiments and response surface methodology (RSM), the optimized PCMC-PS exhibited high activity and
