Excitation Energy Transfer between Porphyrin Dyes on a Clay Surface: A Study Employing Multifidelity Machine Learning

open access: yesAdvanced Theory and Simulations, EarlyView.
Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...

Characteristic Analysis of Adiabatic Spray Absorption Process in Aqueous Ammonia Solution

open access: yesZhileng xuebao, 2013
An absorber is a key device of absorption refrigeration system, and it directly affects the performance of refrigeration system. As an important absorption type, adiabatic spray absorption process disperses the absorption fluid into fine droplets by ...

On the use of cross polarization in solid-state NMR: 1H spin-lock versus adiabatic demagnetization in the rotating frame

open access: yesMagnetic Resonance Letters, 2022
Cross polarization (CP) is a widely used solid-state nuclear magnetic resonance (NMR) technique for enhancing the polarization of dilute S spins from much larger polarization of abundant I spins such as 1H.

Electronic Structure of Kramers Nodal‐Line Semimetal YAuGe and Anomalous Hall Effect Induced by Magnetic Rare‐Earth Substitution

open access: yesAdvanced Science, EarlyView.
The rare‐earth intermetallics YAuGe is identified as a Kramers nodal‐line semimetal, a topological state inherent to non‐centrosymmetric achiral lattices. Magnetic rare‐earth substitution induces an anomalous Hall effect, highlighting the impact of time‐reversal symmetry breaking on topological electronic states and offering insights into designing the

Experimental and numerical analyses of the dynamic failure processes of symmetric Taylor impact specimens

open access: yesEPJ Web of Conferences, 2018
Failure processes encountered in the Taylor impact specimen are of two kinds, Mode II cracks initiating within adiabatic shear bands and tensile cracks. Because friction occurring with the single Taylor configuration influences the failure processes, it ...

Revealing Physical Mechanisms of Spatial Pattern Formation and Switching in Ecosystems via Nonequilibrium Landscape and Flux

open access: yesAdvanced Science, EarlyView.
The universality of the landscape‐flux theory with the mode expansion method for analyzing spatial patterns is illustrated by applying it to vegetation patterns in semi‐arid ecosystems. The framework quantifies global dynamics and most probable transition pathways between ecosystem states under random forcing.

Stable Pincer Gold(III)‐TADF Emitters with Extended Donor–Acceptor Separation for Efficient Vacuum‐Deposited OLEDs with Operational Lifetime (LT95) up to 3831 h at 1000 cd m−2

open access: yesAdvanced Science, EarlyView.
Novel pincer gold(III)‐TADF (thermally activated delayed fluorescence) emitters with extended π‐distances exhibit small singlet‐triplet energy gaps (ΔEST), efficient reverse intersystem crossing (RISC), enhanced radiative decay rates and improved excitons utilization, leading to efficient electroluminescence.
