Selective Solar CO2 Conversion into Ethanol Using Atomic‐Scale Copper Clusters Anchored π‐extended Poly(heptazine imide)

open access: yesSmall, EarlyView.
Atomic‐scale copper clusters anchored on π‐extended poly(heptazine imide) enable selective, sacrificial‐agent‐free solar conversion of carbon dioxide (CO2) to ethanol. The catalyst promotes interfacial charge separation and stabilizes key carbon‐carbon coupling intermediates, providing a molecularly defined platform for direct C2 fuel synthesis under ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

Post‐Arc Transient Dielectric Recovery Characteristics of Vacuum Interrupter in the Large‐Capacity Generator Circuit Breaker

open access: yesHigh Voltage, EarlyView.
ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)

Overcoming environmental constraints to high‐yielding eastern cottonwood productivity in the southeastern United States

open access: yesAnnals of Applied Biology, EarlyView.
The rising demand for biomass highlights Populus deltoides as a productive woody species. A 6‐year study in Sumter County, SC, assessed the effects of irrigation, fertilization, and clonal variation on growth and productivity. Eight clones were studied under two irrigation levels (33 and 1500 kPa) and nutrient rates (high: up to 182 kg N ha−1; low: 50%

Sustainability at the Summit: Transforming Haute Cuisine With Circular Business Models

open access: yesBusiness Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT The adoption of circular economy principles poses a vibrant challenge for firms by becoming a potential and sustainable way for them to keep pace with highly dynamic changes in a competitive environment. Although previous research has examined experiences and practices that firms adopt to facilitate their transition to a circular economy ...
