Research on Stirling-type Low-Temperature Cold Storage at -80 ℃

open access: yesZhileng xuebao, 2023
The use of -80 ℃ low-temperature cold storage is increasing in blood stations, hospitals, and medical research institutions. Low-temperature cold storage primarily uses traditional cascade refrigeration systems.

A Vascular Microphysiological Model of Lung Fibrosis Reveals That Myofibroblasts and IPF Patient‐Derived Fibroblasts Impair Angiogenesis and Vasculogenesis

open access: yesAdvanced Functional Materials, EarlyView.
A microphysiological lung fibrosis model recapitulates myofibroblast–vascular interactions. Induced myofibroblasts and patient‐derived IPF fibroblasts impair angiogenesis and increase vascular permeability via TGF‐β1–driven signaling. Pharmacological interventions with SB 431542 and VEGF supplementation restore vascular morphology and barrier function.

Organic Vegetable Storage in Wales – Opportunities and Constraints [PDF]

open access: yes, 2007
There is a growing interest in buying local produce, but there is insufficient produce available in Wales to meet this demand. One problem is lack of storage. Much organic vegetable produce in Wales is lost by poor storage. ADAS has undertaken this study

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

open access: yesAdvanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

The Value of USDA Situation and Outlook Information in Hog and Cattle Markets [PDF]

open access: yes
This study investigates the impact of six major USDA reports in hog and cattle markets: Cattle; Cattle on Feed; Cold Storage; Hogs and Pigs; Livestock, Dairy, and Poultry Outlook (LDPO); and World Agricultural Supply and Demand Estimates (WASDE). A TARCH-

Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble

open access: yes, 2009
We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed into the atomic coherence by the incident light fields.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

open access: yesAdvanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Energy, exergy, and economic analysis of cold energy storage systems in cold storage using polyethylene glycol phase change material

open access: yesCase Studies in Thermal Engineering
The cold energy storage system using phase change materials (PCMs) is an effective method for reducing energy consumption in cold storage facilities. Its primary objective is to optimize the management of energy storage and consumption.

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a

Qualidade fisiológica de sementes de Araucaria angustifolia (Bertol.) kuntze submetidas a diferentes condições de armazenamento e a escarificação

open access: yesCiência Florestal, 2006
The seeds of Araucaria angustifolia (Bertol.) Kuntze are recalcitrants and, therefore, they lose rapidly the viability after the harvest, limiting their use for nursery production of seedlings.
