Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Effect of soiling agents on disinfection efficacy of a pulsed‐xenon UV lamp towards Listeria monocytogenes on stainless steel surfaces

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This study quantifies the effects of different soils found in the food processing environment on the efficiency of pulsed‐xenon UV disinfection. Abstract Listeria monocytogenes is a foodborne illness that poses a significant threat to human health in young, old, and immunocompromised persons and accordingly, prevention of Listeria contamination is of ...

Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Bridging Theory and Prediction: A Hybrid SEM and Machine Learning Approach to Optimize Lean Construction for Megaproject Sustainability in China

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Construction megaprojects, large‐scale, complex, and capital‐intensive, are particularly prone to inefficiencies, cost overruns, delays, and environmental degradation due to fragmented workflows, stakeholder misalignment, and resource intensity.

A Roadmap to Reduce U.S. Food Waste by 20 Percent [PDF]

open access: yes, 2016
The magnitude of the food waste problem is difficult to comprehend. The U.S. spends $218 billion a year -- 1.3% of GDP -- growing, processing, transporting, and disposing of food that is never eaten.

Rational Design of CdS QDs/CeO2 Nanocube S‐Scheme Heterojunctions for Highly Efficient C2H4 Scavenging in Fresh Produce Preservation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel S‐scheme heterojunction of CdS quantum dots on CeO2 nanocubes was designed to enhance charge separation and oxygen activation for efficient photocatalytic ethylene removal. The optimized composite achieved complete C2H4 degradation within 4 min under low‐intensity visible light, with a rate constant of 1.72 min−1. Mechanistic analysis confirmed

“Passive” Scalecraft as a State Strategy in Post‐Authoritarian Environmental Governance: A Case From South Korea

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT This study employs a scalar politics framework to unpack how participatory rhetoric operates statecraft in a post‐authoritarian context, thereby illuminating hybrid‐regime behavior along a continuum of environmental governance. An examination of the environmental governance of an ecotourism project in South Korea is performed using ...

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.
