Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity

Advanced Functional Materials, EarlyView.
This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Urea coated with poultry litter as an option in the control of nitrogen losses

Revista Brasileira de Engenharia Agrícola e Ambiental
The volatilization of ammonia (NH3) and nitrate leaching (NH3-) are the main processes of nitrogen (N) loss in the soil. The objective of the study was to evaluate N losses by NH3 volatilization and mineral N transformations in the soil with urea coated ...

Nitrogen fluxes from irrigated common‑bean as affected by mulching and mineral fertilization

Pesquisa Agropecuária Brasileira, 2013
The objective of this work was to measure the fluxes of N2O‑N and NH3‑N throughout the growing season of irrigated common‑bean (Phaseolus vulgaris), as affected by mulching and mineral fertilization. Fluxes of N2O‑N and NH3‑N were evaluated in areas with

Adubação com digestato bovino e ureia e seu efeito na volatilização de N-NH3 do Solo

CONTRIBUCIONES A LAS CIENCIAS SOCIALES
O cultivo do milho possui exigência de uma quantidade maior de nitrogênio para obter boa produtividade. Esse macronutriente é suprido por meio da adubação nitrogenada com a ureia, porém, a sua aplicação proporciona elevadas perdas de N, principalmente, por volatilização de amônia (N-NH3).

Dual‐Peptide Nanoplatform: Mesoporous Silica Nanoparticles Functionalized With a Cell‐Penetrating Peptide and Loaded With Rationally Designed Antimicrobial Peptides for Tuberculosis Therapy

Advanced Healthcare Materials, EarlyView.
Machine learning–guided engineering of a plectasin‐derived peptide yields DC05, a potent antimycobacterial candidate. Encapsulation into tuftsin‐functionalized mesoporous silica nanoparticles enhances intracellular delivery, stability, and activity against Mycobacterium tuberculosis while maintaining low cytotoxicity and minimal hemolysis. The combined
