Harnessing Limestone powder to enhance the thermal crack resistance of manufactured sand.

Manufactured sand concrete (MSC) has increasingly applied in engineering. However, how to enhance the thermal crack resistance of MSC has not clearly studied yet, which limits the wide applications of manufactured sand in engineering. We have adopted the method of mixing limestone powder (LP) to make MSC with four mass fractions (wt.

Potassium deficiency enhances imbalances in rice water relations under water deficit by decreasing leaf hydraulic conductance.

Potassium (K) is an essential macronutrient for appropriate plant development and physiology. However, little is known about the mechanisms involved in the regulation of leaf water relations by K under water deficit. A pot experiment with two K supplies of 0.

mediates PM-induced endothelial dysfunction via crosstalk between bronchial epithelial and endothelial cells.

Objective: PM is closely linked to vascular endothelial injury and has emerged as a major threat to human health. Our previous research indicated that exposure to PM induced an increased release of from the bronchial epithelium. However, the role of in PM-induced endothelial injury remains elusive.

Continuous potassium fertilization combined with straw return increased soil potassium availability and risk of potassium loss in rice-upland rotation systems.

Crop residues perform an essential role in the material cycling and energy exchange processes and are commonly used as an organic soil amendment and potassium (K) substitute to enhance field productivity in rice-upland rotation systems. Elucidating the effects of continuous K fertilization combined with straw return on the fate of soil K is of great significance to the scientific application of K fertilization and the sustainable development of the ecological environment. A short-(5 years) and a long-term (38 years) field experiments at the Wuxue (WX) and Wangcheng (WC) sites respectively were conducted to study the effects of continuous K fertilization combined with straw return on soil potassium (K) fertility and loss.

In situ isolation of nuclei or nuclear proteins from adherent cells: a simple, effective method with less cytoplasmic contamination.

Background: Isolation of nuclei or nuclear proteins is a prerequisite for western blot, nuclear proteome profiling, and other evaluations of nuclear proteins. Here, we developed a simple method for in situ isolation of nuclei or nuclear proteins by in situ removing the extranuclear part of adherent cells via a classical nonionic detergent triton X-100.

Results: First, the feasibility of our method was confirmed by confocal microscopy, atomic force microscopy, scanning electron microscopy, dynamic light scattering, immunofluorescence imaging, and time-lapse dynamic observation.

In Situ Growth of Iron Sulfide on Fast Charge Transfer V C-MXene for Superior Sodium Storage Anodes.

Due to the upstream pressure of lithium resources, low-cost sodium-ion batteries (SIBs) have become the most potential candidates for energy storage systems in the new era. However, anode materials of SIBs have always been a major problem in their development. To address this, V C/Fe S @C composites with hierarchical structures prepared via an in situ synthesis method are proposed here.
