Blockchain-Based Cold Chain Traceability with NR-PBFT and IoV-IMS for Marine Fishery Vessels

Journal of Marine Science and Engineering
Due to limited communication, computing resources, and unstable environments, traditional cold chain traceability systems are difficult to apply directly to marine cold chain traceability scenarios. Motivated by these challenges, we construct an improved

Asset Redeployability and Biodiversity Risk

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine how asset redeployability influences a firm's exposure to biodiversity risk. Our empirical analysis provides robust evidence that firms possessing greater levels of redeployable assets exhibit significantly lower biodiversity risk.

Challenges in meeting the mass transfer demands of high‐density perfusion cultures in single‐use bioreactors

Biotechnology Progress, EarlyView.
Abstract Increasing protein therapeutics production by adopting intensified perfusion cultures places high demand on the mass transfer capabilities of single‐use bioreactors (SUB). Here, we compare these capabilities for four SUB designs against worst‐case O2 transfer requirements for supporting Chinese hamster ovary (CHO) perfusion cultures. Impact of

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,
