Published: July 2012

A study of the normal modes of vibration and their dispersion in polyfuran (Pfu) based on the Urey-Bradley force field is reported. It provides a detailed interpretation of IR and Raman spectra. Characteristic features of dispersion curves such as regions of high density-of-states, repulsion and character mixing of dispersive modes are discussed. Predictive values of heat capacity as a function of temperature are calculated.

Along with the rapid development of the digital economy and artificial intelligence, heat sinks available for immersion phase-change liquid cooling (IPCLC) of chips are facing huge challenges. Here, we design a high-performance IPCLC heat sink based on a copper microgroove/nanocone (MGNC) composite structure. Maximal heat fluxes () of the MGNC structure, microgroove structure, and flat copper reach 112.

This study was aim to investigate the effects of lipoic acid (ALA) on performance, meat quality, serum biochemistry and antioxidant function of broilers under heat stress (HS). Two hundred1-day-old Cobb broilers were randomly divided into four treatment groups and each treatment consisted of 4 replicates of 10 broilers each. The treatment group adopts a 2 × 2 two-factor setting, which is divided into two diets (basic diet or 250 mg/kg ALA diet) and two temperatures (24 ± 1℃ or 33 ± 1℃).

As global demand for plant-based foods increases due to their nutritional and environmental benefits, young jackfruit () is emerging as a promising meat alternative. This study evaluates the effects of heat treatments-specifically blanching for 5 min and boiling for 15, 30, and 45 min-on the quality and sensory attributes of jackfruit-based meatballs. The results indicate consistent color values ( , , and ) across the samples, with values ranging from 53.

The scleractinian corals conduct various responses upon heat stress such as bleaching and tissue loss, and colonies from the same coral species can conduct differential physiological activities with the biochemical basis unknown. In the present study, factors that influence the heat stress responses in coral Pocillopora damicornis were investigated. It was observed that P.
