Criterios para la selección y aplicación de lubricantes
, 1998 El hombre en la búsqueda de reducir el esfuerzo físico (consumo de energía) para transportar, inventó la rueda. Pero, igualmente, se percató que dos superficies cuando entran en contacto producen fricción y pérdida de energía. Por esta razón busco la forma de agregar algo entre las superficies en contacto, con el propósito de evitar el desgaste y ...

Advanced Science, EarlyView.A root‐inspired microneedle array patch uses lattice‐based mechanical interlocking to unite rigid microneedles with a flexible substrate. The interlocked rigid–soft architecture improves interfacial bonding, supports stable adhesion on curved and wet tissues under dynamic motion, and provides a versatile platform for robust biointerfacing and future ...

Gestión Integral de los Aceites Lubricantes Usados
La relación entre medio ambiente y desarrollo se centra en el concepto de “desarrollo sostenible”, la sostenibilidad del sistema global del que el sistema es parte. Si la actual escala de la actividad económica crea problemas de equilibrio para la estabilidad de la biosfera, continuar aumentando el crecimiento económico en las condiciones en las que se

Chelation Drives Surface Substitution in Hybrid‐MXenes
Angewandte Chemie, EarlyView.We demonstrate ethylenediamine‐derived bidentate binding on Ti3C2 by controlled deprotonation of ─NH2 groups during reaction with Ti3C2Br2. XRD, XPS, ssNMR, STEM, DFT, and INS confirm the bidentate coordination and the superior stability of chelating modes, while AIMD reveals proton transfer and new surface imine–Ti bonding mode.

AIChE Journal, EarlyView.Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.
