Thermoplastic polyamide elastomers (TPAEs) have emerged as important thermoplastic elastomer materials with significant potentials owing to their excellent low‐temperature flexibility, easy processability, lightweight, good thermal stability and mechanical properties, etc. Over the last few decades, TPAEs have rapidly developed into a large variety of kinds of TPAEs. Striking advancements have been achieved in this research field. Unfortunately, there is not yet a review to summarize the progress. The present paper summarizes the major advancements dealing with TPAEs, in which synthesis, structures/properties as well as applications are introduced in detail. Moreover, current challenges and main developmental directions dealing with TPAEs are also presented. This review may motivate more interest in TPAEs, further facilitating their all‐side research and more large‐scale applications.

In meat processing, changes in the myofibrillar protein (MP) structure can affect the quality of meat products. High hydrostatic pressure (HHP) has been widely utilized to change the conformational structure (secondary, tertiary and quaternary structure) of MP so as to improve the quality of meat products. However, a systematic summary of the relationship between the conformational structure (secondary and tertiary structure) changes in MP, gel properties and product quality under HHP is lacking. Hence, this review provides a comprehensive summary of the changes in the conformational structure and gel properties of MP under HHP and discusses the mechanism based on previous studies and recent progress. The relationship between the spatial structure of MP and meat texture under HHP is also explored. Finally, we discuss considerations regarding ways to make HHP an effective strategy in future meat manufacturing.

Changes in the structure of tropomyosin (TM) altered the texture profiles of eel balls and the inhibitory activity of the angiotensin-converting enzyme (ACE).

La(III)/AC adsorbents were prepared by ultrasonic impregnation. The optimal preparation conditions of La(III)/AC were studied by calcination temperatures and La-loaded amount. Competition adsorption desulfurization from aromatics and adsorption mechanism were investigated onto La(III)/AC. Benzene, methylbenzene and naphthalene were selected to explore adsorption mechanism on dibenzothiophene (DBT). The results showed that La(III)/AC with calcination temperature for 803 K and La-loaded amount for 2 wt % possessed more effective performance of desulfurization. La(III) helped to enhance adsorptive capacity and selectivity, the effective degree of the aromatics over La(III)/AC for DBT removal decreased in the order naphthalene, methylbenzene and benzene. It was founded that the adsorption mechanism was mostly like to be π complex. Adsorption isotherms and kinetics were investigated, and the parameters were obtained. Results showed that adsorption isotherms could be well fitted by Langmuir model and maximum adsorption capacities increased with the temperature increasing. Adsorption kinetics could be represented by pseudo-second-order model, which suggested that chemical reaction along with electronic transfer and share seemed significant in the adsorption rate-controlling step. Adsorption process was spontaneous and exothermic.
