Determining thermal conductivity of lateritic ores from Hot-Ball method
Minería y Geología, 2019 The thermal conductivity of lateritic ores was determined by using the transitory commonly known Hot- Ball method. An experimental facility was built and an experimental design was used for analyzing the property performance for three temperature values.

Intermixing‐Driven Growth of Highly Oriented Indium Phosphide on Black Phosphorus
Advanced Functional Materials, EarlyView.This study demonstrates controlled intermixing and compound formation at the In/black phosphorus (BP) interface, leading to highly oriented InP formation. Comprehensive structural and electrical analyses reveal tunable bandgap behavior governed by competing BP thinning and charge‐transfer effects, underscoring the critical role of interfacial compound ...

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 ...

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.An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Advanced Functional Materials, EarlyView.In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...
