Numerical Investigation on the Service Life of a Liquid Rocket Engine Thrust Chamber
Metals, 2023 Rocket engine thrust chambers withstand very high temperatures and thermal gradients during service that induce multiple damaging phenomena such as plasticity, low-cycle-fatigue (LCF) and creep.

Business Strategy and the Environment, EarlyView.ABSTRACT Adopting a signaling perspective, this study examines whether corporate green patenting reduces the cost of equity by mitigating information asymmetry in capital markets. Using longitudinal panel data from South Korea, we find that green patenting—encapsulating technological innovation related to energy, environmental protection, and climate ...

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...
