Prediction of the fouling thermal resistance on the sulphydric acid coolers
Minería y Geología, 2018 Heat exchangers’ fouling causes increased resistance to thermal exchange, with subsequent efficiency loss. Although related analysis has been exposed in previous studies, the available mathematical models do not consider all forms and mechanisms of ...

Advanced Functional Materials, EarlyView.A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.

Flexible Leaf‐Like Fuel Cell From Plasmonic Janus Nanosheet
Advanced Functional Materials, EarlyView.A flexible leaf‐like fuel cell is fabricated by conductive gold nanowire sponge‐supported plasmonic Janus nanosheet, which can generate a power of 8.93 mW cm⁻2 with less than 10% performance deterioration even being bent or twisted. Further assembly in a tree‐like layout demonstrates omnidirectional light harvesting capability and wind resistance ...

Evolution semigroups for nonautonomous Cauchy problems
Abstract and Applied Analysis, 1997 In this paper, we characterize wellposedness of nonautonomous, linear Cauchy problems (NCP) {u˙(t)=A(t)u(t)u(s)=x∈X on a Banach space X by the existence of certain evolution semigroups.

Advanced Functional Materials, EarlyView.This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.
