Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

Advanced Functional Materials, Volume 36, Issue 49, 18 June 2026.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, Volume 55, Issue 3, Page 1608-1638, May 2026.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Análisis de Flujos de Potencias Ineficientes Producidos por Convertidores de Potencia [PDF]

Información tecnológica, 2014
Este articulo presenta un analisis de los flujos de potencia ineficientes provocados por los convertidores de potencia. En base a la teoria de la potencia del estandar IEEE 1459 (2010) y partiendo de la potencia causada por las corrientes armonicas (DeI), se proponen las potencias DeI_low y DeI_high para cuantificar los flujos de potencia ineficiente ...

Interactions Between Dissolved Organic Carbon and Aluminium Activity in Tropical and Temperate No‐Till Agroecosystems

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters
