Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Toposseqüências de Latossolos originados de rochas basálticas no Paraná: II - relação entre mineralogia da fração argila e propriedades físicas dos solos Oxisol toposequences developed from basaltic rocks in Paraná State, Brazil: II - relationship between clay fraction mineralogy and physical soil properties

open access: yesRevista Brasileira de Ciência do Solo, 2006
A estrutura do solo (tipo, tamanho e grau de desenvolvimento) define a porosidade total do solo e a distribuição relativa entre macro e microporos, sendo considerada uma das mais importantes propriedades do solo do ponto de vista agrícola.

Habitat structure: a fundamental concept and framework for urban soil ecology [PDF]

open access: yes, 2007
Habitat structure is defined as the composition and arrangement of physical matter at a location. Although habitat structure is the physical template underlying ecological patterns and processes, the concept is relatively unappreciated and underdeveloped

New Insights into Atonic Postpartum Hemorrhage: Animal Model Construction Based on Placental Nanodelivery Systems

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a placenta‐targeted nanodelivery system co‐loading HMGB1 protein and the NLRP3 agonist nigericin to establish an animal model of atonic postpartum hemorrhage. The model accurately recapitulates clinical phenotypes, including prolonged labor and uterine contractility dysfunction, while revealing inflammatory activation in placental ...
