Summary: The study confirmed the reliability of DSC in evaluating cartilage changes and the correlation between storage time and graft quality. Deep-freezing was found to have a significant impact on cartilage, with thermal parameters changing after long-term storage. Further detailed analysis is needed to determine the effects of deep-freezing.

Summary: This paper focuses on the challenges and questioning of long-term thermochemical heat storage for household applications, highlighting the significant thermal losses in seasonal thermochemical storage. The study suggests that the energy storage density based on solid hydrates or aqueous solutions may not be practical for long-term thermal energy storage for domestic hot water and heating.

Summary: This study compares different absorption thermal battery cycles from various criteria perspectives, including energy storage efficiency, energy storage density, and exergy efficiency. The results show that the double-effect compression-assisted cycle can simultaneously improve energy storage efficiency and density and bridge the temperature gap. This is of great importance for achieving high-density and high-efficiency thermal energy storage.

Summary: The study showed that air velocities, stepwise in-bag ageing, and ageing time have limited effects on the oxidative stability, proteolysis, and digestibility of dry-aged lean beef. In-bag dry-ageing improved the lipid and protein oxidative stability of beef during long-term frozen storage. The high lipid and protein oxidative stability of long-term frozen lean beef produced using a stepwise in-bag ageing process suggests potential for export of dry-aged meat.

Summary: The progress of engineering technologies greatly affects the development of methods for improving areas contaminated with heavy metals. This study evaluated the effectiveness of aided phytostabilization in immobilizing heavy metals in soils under variable temperatures using freezing-thawing cycles. Diatomite amendment and Lolium perenne L. were used, and the distribution of heavy metals in different soil fractions, as well as their accumulation in plants and soil microbial composition, were investigated. The results showed that diatomite amendment increased above-ground biomass yield and stability of heavy metals in phytostabilized soils. Freezing-thawing cycles also had a positive impact on the stability of certain heavy metals. The study also revealed changes in soil microbial composition due to freezing-thawing cycles.

Summary: The influence of ultrasound-assisted immersion freezing on the quality and physicochemical properties of chicken breasts during frozen storage was investigated. The results showed that ultrasound-assisted immersion freezing reduced ice crystal size and decreased thawing and cooking losses. This treatment also minimized muscle structure deterioration and color deterioration compared to other freezing methods.

Summary: Low-temperature biopreservation is commonly used for medication storage to prolong their shelf life. However, cryo-injury can occur during cryopreservation, making it crucial to find a way to achieve long-term biopreservation without causing harm. The optimal storage temperature for different biomaterials should be investigated to improve storage efficiency. This review discusses the mechanisms of cryo-injury and biopreservation, as well as the reasons for storing biological tissues at various temperature zones. It provides valuable insights for the development of biostorage technology.

Summary: The Stirling/pulse tube cryocooler (SPC) is a highly efficient and long-lasting cryocooler for space applications. It has the ability to adjust the inter-stage refrigeration capacity dynamically by controlling the Stirling displacer in the first stage. This paper proposes an SPC with a second-stage active phase shifter (APS) that can control the phase difference at the second-stage hot end in real time. The experimental results show that the SPC with the APS can provide refrigeration capacity at different temperatures, with a minimum temperature of 13.5K.

Summary: This article details three models of different complexity levels for predicting the cold production of a solar cooling device and compares their advantages and disadvantages. The results show that the transient model underestimates the cold generation, while the equilibrium model and universal model overestimate it. The transient model is a useful tool for analyzing the impact of different variables in a solar adsorption refrigeration system, while the simpler models can be used for preliminary design and feasibility studies.
