Cold chain disruption and refrigeration failures are common issues in the logistics of perishable food products. In these cases, the use of pallet covers should be very useful, delaying the increase of product temperatures inside the pallets until cooling conditions are restored. However, there are no studies about the performance of pallet covers in these types of situations, which could persist for hours. This paper evaluates the performance of three different types of cold chain covers versus having no cover for three different types of vegetables (chard, cucumbers, and carrots). A refrigeration failure during the cold chain was simulated. The three covers presented an improvement in temperature loss compared to the no-cover situation, with the average time for the temperature to increase from 4 to 10 °C with a cover being a range of 214 to 506 min, while for no cover, from 162 to 211 min. Relative humidity (RH) always presented improved preservation with a cover than with no cover, except for one case. The correlation between the thermal images and sensor temperatures was also studied.

A portable gas chromatograph-mass spectrometer (GC-MS) is an effective instrument for rapid on-site detection of volatile organic compounds (VOCs). Current instruments typically adsorb samples at ambient temperature, challenging the detection of low-boiling VOCs. In this study, a low-temperature adsorption thermal desorption method is proposed for sample enrichment in a portable GC-MS.

The repurposing of statins as neuroprotective agents and/or anti-brain tumor drugs is limited by challenges in brain bioavailability and systemic off-target effects. Therefore, improved and targeted delivery of statins to the brain is necessary. This study aimed to develop a high-strength liquid formulation of the poorly soluble prodrug simvastatin for intranasal administration, as a strategy to achieve high brain concentrations of the prodrug and/or its active form, tenivastatin.

Barocaloric (BC) materials offer the potential for highly energy-efficient refrigeration by generating heat absorption through the effect of pressure on a solid-solid phase transition. However, very few of the known materials have the required phase transition in the temperature regions necessary for domestic refrigeration or air conditioning. We introduce organic ionic plastic crystals (OIPCs) as a new family of BC materials.

Hydrogen sulfide (HS) is an metabolic product of tuna during the spoilage, and relationship between HS and tuna quality has not been specifically studied. This study detected changes in HS content, HS precursor substances, and related enzymes based on the formation pathway of HS. HS content increased of tuna resulted in significant increases in contents of cystathionine β-synthase, cystathionine γ-lyase, 3-mercapto pyruvate sulfotransferase, cysteine aminotransferase and methionine, while content of cysteine decreased which provided HS formation.

Biomass-derived porous carbon (PC) has emerged as a promising candidate for electrode materials in energy storage applications, effective pretreatment of the precursor is a key strategy for enhancing the electrochemical performance of PC. However, challenges remain in achieving this goal through environmentally friendly, simple, and efficient methods. In this paper, a dual-frequency ultrasonic-assisted enzymolysis strategy combined with carbonization-activation method was proposed to prepare high-performance garlic peel-derived PC (DUGPC) for supercapacitors.
