Ab Initio Study of Fine and Hyperfine Interactions in Triplet POH

open access: yesMolecules, 2022
Phosphorous-containing molecules have a great relevance in prebiotic chemistry in view of the fact that phosphorous is a fundamental constituent of biomolecules, such as RNA, DNA, and ATP.

On a generalized relaxed Saint–Venant principle

open access: yesBoundary Value Problems, 2018
The goal of this paper is to obtain an extension of the relaxed Saint–Venant principle in order to cover the thermoelasticity of dipolar porous bodies. According to this principle, for a finite time t>0 $t>0$, we identify a bounded domain Dt $\mathcal{D ...

On vibrations in Green-Naghdi thermoelasticity of dipolar bodies

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
This study is concerned with the theory of thermoelasticity of type III proposed by Green and Naghdi, which is extended to cover the bodies with dipolar structure.

A dipolar structure in the heat-flux dependent thermoelasticity

open access: yesAIP Advances, 2018
Our study is concerned with the mixed initial-boundary value problem for a dipolar body in the context of a heat-flux dependent theory for the dipolar thermoelastic bodies.

A study on the thermoelasticity of three-phase-lag dipolar materials with voids

open access: yesBoundary Value Problems, 2019
With a wide applicability in solid state mechanics, the theory of continuous dipolar materials with voids is a distinctive part of microstructure theory, a theory that emerged with the necessity of eliminating the discrepancies between the classical ...

Aeromagnetic anomalies and structure of the Iztaccíhuatl-Popocatépetl volcanic region in Central Mexico [PDF]

open access: yesGeofísica Internacional, 2002
Popocatépetl volcano is characterized by a high amplitude dipolar anomaly that is normally polarized and centered on the summit cone. The anomaly shows the effects of topographic relief and of major fault zones.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

open access: yesAdvanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...
