(In)certezas sobre la crisis ambiental (Un)certainties on the environmental crisis
Ambiente & Sociedade, 2001 A maioria dos artigos e livros sobre a questão ambiental parte da existência de uma série de problemas ambientais no nível global sem colocar as incertezas que tal informação apresenta. Neste artigo consideramos os dois principais problemas ambientais de escala planetária, o câmbio climático e a perda da biodiversidade.

REFLEXIÓN SOBRE LA CRISIS AMBIENTAL CONTEMPORÁNEA
, 2023 La crisis ambiental es un problema global que requiere una acción colectiva para abordarlo. Se han establecido tratados internacionales para promover la protección y la sostenibilidad del medio ambiente. Sin embargo, se ha cuestionado la eficacia de estos tratados para abordar cuestiones ambientales en América Latina.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Desarrollo y Responsabilidad. ¿Posible conciliación?
Ideas y Valores, 2022 En este artículo pretendemos analizar la posición de Hans Jonas en relación con las llamadas teorías del desarrollo, colocándolo entre los críticos de la idea de crecimiento, aunque no entre los tecnófobos.

Advanced Functional Materials, EarlyView.Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Medellín: una ciudad en crisis ambiental.
Revista Kavilando, 2019 Resumen. La ciudad de Medellín afronta, a raíz del modelo económico desarrollado, una profunda crisis ambiental y a pesar de los diagnósticos y emergencias ambientales, lo cierto es que la gestión ambiental implementada dista mucho de ofrecer resultados exitosos para el mejoramiento de las condiciones ambientales.
