Regio‐ and Diastereoselective C–C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts

open access: yesChemistry – A European Journal, EarlyView.
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.

Multi-objective decoupling control strategy for low voltage ride through under asymmetrical faults

open access: yes电力工程技术
For the traditional low voltage ride through control under asymmetrical faults, due to the limited control degrees of freedom, the grid-connected inverter control suffers from the problem of not being able to simultaneously realize the output current ...

Influence of Carboxylate Ligand Variation on Structure, Magnetic Exchange, and Magnetocaloric Performance in Hexanuclear Gd(III) Complexes

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Hexanuclear cyclic Gd(III) coordination compounds are promising candidates for magnetic and magnetocaloric applications, yet systematic series remain rare due to synthetic challenges. We report the synthesis and characterization of five new complexes with the general formula [Gd(H3bt)(carboxylate)]6, employing four different carboxylate ...

Structural and Biological Insights Into Copper(I) Phosphane Complexes With Boron‐Phenylated Poly(3‐(CF3)Pyrazolyl)‐ and Poly(6‐(CF3)‐2‐pyridyl)‐Borates

open access: yesChemistry – A European Journal, EarlyView.
This study reports six new copper(I) complexes with unusual coordination and strong anticancer activity against a panel of human cancer cell lines derived from different solid tumors. The most active compounds outperform cisplatin, even in resistant cells, by inhibiting protein disulfide isomerase and inducing redox stress that triggers non‐apoptotic ...

A hidden Markov model and reinforcement learning‐based strategy for fault‐tolerant control

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study introduces a data‐driven control strategy integrating hidden Markov models (HMM) and reinforcement learning (RL) to achieve resilient, fault‐tolerant operation against persistent disturbances in nonlinear chemical processes. Called hidden Markov model and reinforcement learning (HMMRL), this strategy is evaluated in two case studies

Boards of Directors That Transform: A Study on How Specific Architectural Components Drive ESG Performance

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the potential influence of key components of the board of directors' architecture on ESG outcomes. Specifically, we focus on the effects of demographic components (gender and cultural diversity), structural and compositional factors (size, CEO‐Chair separation, and the presence of independent/non‐executive directors), and ...

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

A Voltage Sag Generator for Wind Power Generation Using Contactors and IGBTs

open access: yesKongzhi Yu Xinxi Jishu, 2017
In view of the existing transformer form, VSG design scheme is limited by its switch devices, and the voltage sag time can not be accurately controlled. It presented a design scheme of three-phase VSG based on three-phase autotransformer, which used IGBT
