Zinc Sulfide Enabling Remarkable Surface Passivation of Crystalline Silicon

Advanced Energy Materials, EarlyView.
Polycrystalline ZnS films capped by Al2O3 provide outstanding surface passivation performance. The excellent lattice agreement between c‐Si and ZnS combined with a hydrogenation step result in extremely low interface state density (≈ 1×1010 cm−2 eV−1) and recombination current pre‐factor (1.0 fA/cm2), revealing a new passivation strategy for ...

Optimal allocation of multi-type FACTS devices in power systems based on power flow entropy

Journal of Modern Power Systems and Clean Energy, 2014
Flexible AC transmission systems (FACTS) devices can effectively optimize the distribution of power flow. Power flow entropy can be applied as a measure of load distribution.

i‐Tac: Inverse Design of 3D‐Printed Tactile Elastomers with Tuneable Optical and Mechanical Properties

Advanced Intelligent Systems, EarlyView.
Inspired by the multi‐tissue architecture of the human fingertip dermis (A), this work introduces a mixture design using three PolyJet materials (AC/TM/GM) to expand the achievable elastomer property space (B). An inverse design pipeline (i‐Tac) is developed to map target optical/mechanical requirements to optimal material compositions (C), enabling ...

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

The Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Addressing the Energy Trilemma: The Role of Entrepreneurship, Regulation, and Climate Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT Balancing energy security, energy equity, and environmental sustainability has become increasingly challenging as economies pursue low‐carbon growth amid climate risk and persistent disparities in access to modern energy. Although entrepreneurship is widely recognized as a driver of innovation, its role in addressing the energy trilemma ...
