Gold(I) Phosphine/Phosphido‐Borohydride Complexes

European Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

Consecutive (Pseudo‐)Four‐Component Synthesis of Meta‐ and Ortho‐Biaryl Triarylamines with Tunable Emission and Redox Properties

European Journal of Organic Chemistry, EarlyView.
The combination of Suzuki and Buchwald–Hartwig coupling in (pseudo‐)four‐component reactions paves an efficient one‐pot route to twisted, redox‐active triarylamine (TAA) emitters. Biaryl substitution patterns and para‐substituents serve as key levers for tuning redox potentials, as well as absorption and emission energies, complemented and, by time ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Analytical Floor Response Spectra for Performance‐Based Seismic Design of Non‐structural Elements in Reinforced Concrete Frame Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Damage to non‐structural elements significantly impacts the seismic performance of buildings in terms of economic and functionality losses. Consequently, performance‐based seismic design of non‐structural elements has become a key pillar of a comprehensive building‐seismic resilience strategy, for instance, through loss‐targeted earthquake ...

Lateral-torsional coupled vibration analysis of a bolted joint rotor system considering rotor-stator rub-impact

Results in Engineering
The interaction of a rotor with a stationary part is a serious malfunction that could lead to a failure. The past studies on rotor-stator rub-impact behaviors mainly addressed the vibrations along the lateral directions, where the torsional vibration of ...

Electronic jelly: Engineering the mechanics of hydrogels for flexible electronics

FlexMat, EarlyView.
By unifying mechanical reinforcement strategies—double networks, structural ordering, and dynamic interactions—this review demonstrates how engineered hydrogels can transcend their fragility to achieve the strength, toughness, and reliability required for flexible electronics, including wearable sensors, energy devices, and soft robotic systems ...
