Embedding polydopamine in keratin-based biohydrogels for efficient dye removal.

Keratin-based hydrogels have shown promise as materials for wastewater remediation, yet their low surface area and poor mechanical performance hindered the practical application. To address these challenges, we developed a bowl-shaped polydopamine-loaded sponge bio-hydrogel (BPSH) with a hierarchical porous structure and high stability. The extruded keratin chains facilitated the formation of three distinct macroporous frameworks, while embedding bowl-shaped polydopamine into the bio-hydrogel significantly enhanced the hierarchical porous structure.

synthesized perovskite/polyhedral oligomeric silsesquioxane nanocomposites for robust X-ray imaging.

Perovskites are extensively studied in scintillation detection due to their low cost, simple synthesis, high scintillation light yield, and rapid decay times. However, their instability to light and radiation leads to scintillation performance degradation. To address these stability concerns, this paper proposes a new perovskite nanocrystal (NC) synthesis method that employs aminopropyllsobutyl polyhedral oligomeric silsesquioxane (POSS) as a ligand and a coating layer to passivate the perovskite NCs, significantly enhancing their stability and photoluminescence efficiency.

Green manuring relocates microbiomes in driving the soil functionality of nitrogen cycling to obtain preferable grain yields in thirty years.

Fertilizers are widely used to produce more food, inevitably altering the diversity and composition of soil organisms. The role of soil biodiversity in controlling multiple ecosystem services remains unclear, especially after decades of fertilization. Here, we assess the contribution of the soil functionalities of carbon (C), nitrogen (N), and phosphorus (P) cycling to crop production and explore how soil organisms control these functionalities in a 33-year field fertilization experiment.

Gate-voltage-modulated electrostatic interaction between the probe and the channel material of FET biosensors for detecting telomerase.

A gate-voltage-modulated strategy was proposed to improve the detection performance of telomerase. We comprehensively investigated the mechanism for the gate-voltage-modulated detection performance by modulating the electrostatic interaction between charges of a single-stranded DNA probe and electrons of the InO channel. This gate-voltage-modulated interaction between the probe and the channel can potentially serve as a universal strategy for high-performance FET biosensors.

Porous MgO-modified biochar adsorbents fabricated by the activation of Mg(NO) for phosphate removal: Synergistic enhancement of porosity and active sites.

Engineering magnesium oxide (MgO)-modified biochar (MgO-biochar) with high porosity and active MgO load is a feasible pathway to enhance phosphate adsorption capacity. However, the blockage to pores caused by MgO particles is ubiquitous during the preparation, which seriously impaired the enhancement in adsorption performance. In this research, with the intent to enhance phosphate adsorption, an in-situ activation method based on Mg(NO)-activated pyrolysis technology was developed to fabricate MgO-biochar adsorbents with abundant fine pores and active sites simultaneously.

Synergistic effects of diazotrophs and arbuscular mycorrhizal fungi on soil biological nitrogen fixation after three decades of fertilization.

Biological nitrogen (N) fixation (BNF) via diazotrophs is an important ecological process for the conversion of atmospheric N to biologically available N. Although soil diazotrophs play a dominant role in BNF and arbuscular mycorrhizal fungi (AMF) serve as helpers to favor BNF, the response of soil BNF and diazotrophic communities to different long-term fertilizations and the role of AMF in diazotrophs-driven BNF are poorly understood. Herein, a 33-year fertilization experiment in a wheat-maize intercropping system was conducted to investigate the changes in soil BNF rates, diazotrophic and AMF communities, and their interactions after long-term representative fertilization (chemical fertilizer, cow manure, wheat straw, and green manure).

Coupling Novel Probes with Molecular Localization Microscopy Reveals Cell Wall Homeostatic Mechanisms in .
