Article Abstract
Energy decay, describing the leakage of system energy to the environmental bath, is a universal behavior in oscillators. It has been utilized to elucidate energy transfer between vibrational modes of a resonator. In coupled resonators, achieving an ultra-low coupling rate is essential for observing energy interactions between resonators and environmental bath. Here, we observe periodic transient beating phenomenon by analyzing the transient responses of coupled nonlinear resonators with a coupling rate of 9.6 Hz. The energy transfer rate indicating the hybrid energy manipulation is impacted by asymmetry-induced energy localization and enhanced by nonlinearity. Time-resolved eigenstates, characterized by amplitude ratios, are employed as a quantitative tool to uncover the energy transfer and localization in coupled resonators under nonlinear operations. This work opens the possibilities to manipulate energy transfer, to probe energy localization, and to develop high-precision sensors utilizing the energy transfer between coupled nonlinear resonators.

Context: This study investigates the radiation tolerance of a SiGe source vertical tunnel field effect transistor (VTFET) under heavy ion-induced single event effects (SEEs). Single event effects (SEEs) occur when high-energy particles interact with semiconductor devices, leading to unintended behavior. The effect of high energy ions on the VTFET is examined for various linear energy transfer (LET) values and at multiple ion hit locations.

The development of innovative bioprocessing technologies has resulted from the growing global need for sustainable forms of energy and environmentally friendly waste treatment. In this review, we focus on the combined electro-fermentation and microbial fuel cells, as they form a hybrid system that simultaneously addresses wastewater treatment, bioenergy production, and bioplastics. Even though microbial fuel cells produce electricity out of the organic waste by the use of electroactive microorganisms, electro-fermentation improves the microbial pathways through the external electrochemical management.

Carbon-hydrogen bond activation is a pillar of synthetic chemistry. While it is generally accepted that Pd is more facile than Ni in C-H activation catalysis, there are no experimental platforms available to directly compare the magnitude of C-H bond weakening between Ni and Pd prior to bond scission. This work presents the first direct measurements of C(sp)-H bond acidity (p) and bond dissociation free energy (BDFE) for a species containing a ligated alkane-palladium interaction (RCH···Pd), also known as an agostic interaction.

Light-harvesting complex IIs (LHCIIs) are the major antenna in higher plants, balancing light capture through photoprotection. While it naturally forms trimers, stress conditions can induce monomerization, altering pigment interactions. Here, we explored how molecular oxygen affects triplet excited-state dynamics in LHCII monomers using time-resolved transient absorption spectroscopy under aerobic and anaerobic conditions.

The formation of carbinolamine represents the crucial initial step in the aldol reaction, specifically involving the interaction between p-nitrobenzaldehyde and acetone, facilitated by amine-catalyzed mesoporous silica nanoparticles (amine-MSN). In this process, a nitrogen atom from propylamine, which acts as the catalytic moiety, engages in the formation of a covalent bond with a carbon atom from acetone, leading to the generation of a carbinolamine intermediate. This reaction is significantly influenced by the presence of silanol groups located on the surface of the amine-MSN, which contribute to the catalytic activity.
