Absorção real, perdas endógenas e exigência de fósforo para suínos em final de crescimento, pela técnica da diluição isotópica True absorption and endogenous fecal losses of phosphorus for swine in the final of the growing based on the isotopic dilution techinique

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 1999
Determinaram-se as perdas endógenas mínimas, a exigência de fósforo e a absorção real do fósforo do fosfato bicálcico em suínos no final da fase de crescimento, pela técnica da diluição isotópica. Foram utilizados 20 leitões híbridos comerciais, com peso

Chlorine isotope composition in chlorofluorocarbons CFC-11, CFC-12 and CFC-113 in firn, stratospheric and tropospheric air [PDF]

, 2014
The stratospheric degradation of chlorofluorocarbons (CFCs) releases chlorine, which is a major contributor to the destruction of stratospheric ozone (O3).

Using High‐Throughput Screening to Identify Crosslinking Peptides That Control Cell‐Mediated Matrix Degradation

Advanced Healthcare Materials, EarlyView.
Protease‐degradable hydrogels mimic dynamic cell‐matrix interactions, but controlling hydrogel degradation is a challenge. We screen libraries of peptides to identify sequences that are primarily degraded by membrane‐localized proteases. Crosslinking hydrogels with these peptides enables cell to spread and migrate while reducing matrix degradation ...

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

Advanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.
