Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Structural characteristics, compression and strength properties of plain weft-knitted fabrics before and after washing [PDF]

open access: yesTekstilna industrija, 2023
The structural characteristics, compression, and strength properties of knitted fabrics, before and after washing, were investigated in this paper. The experimental material consisted of three plain weft-knitted fabrics produced of cotton, wool, and ...

Down‐regulation of Shh in the hair follicles of mice during chemotherapy‐induced hair loss is mediated by the JAK/STAT1 signaling pathway

open access: yesFEBS Open Bio, EarlyView.
We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.

Creating a new type of concrete by using waste electrical cable plastic and waste electrical cable rubber: as a sustainable approach

open access: yesSustainable Structures
Solid waste is among the World's most critical environmental issues. One of the most significant shares of total solid waste is occupied by electronic waste. One way to reduce waste is to use it as an aggregate in Sustainable Concrete (SC).

Contribution to evaluation of mechanical properties during impact loading [PDF]

open access: yesMetalurgija, 2008
The paper analyzes the influence of the impact rate of up to 120 ms-1 with a constant energy on the relative compression of high-grade unalloyed steels, Cu and Zn, and the evaluation of energy consumed during the impact bending test at the impact rate of

Engineering tandem VHHs to target different epitopes to enhance antibody‐dependent cell‐mediated cytotoxicity

open access: yesFEBS Open Bio, EarlyView.
Tandem VHH targeting distinct EGFR epitopes were engineered into a monovalent bispecific antibody (7D12‐EGA1‐Fc) with more potent ADCC without increasing affinity to EGFR. Structural modeling of 7D12‐EGA1‐Fc showed cross‐linking of separate EGFR domains to enhance CD16a engagement on NK cells.

Compressive Strength Properties of Snow [PDF]

open access: yesJournal of Glaciology, 1959
AbstractThe compressive strength of snow cylinders was investigated as a function of the age of the snow from which the cylinders were made, the snow particle size and the age of the cylinders. The results show that the compressive strength is reduced if the snow is older, if the particle size is smaller, or if the cylinders are younger.

Criterion assessment of the possibility to prolong the service life limit of the helicopter tail drive shaft

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017
Low life time of home-produced helicopter transmission elements in comparison with foreign analogues is one of the problems of Russian helicopter industry. For example, the service life limit of Mi-2 drive shaft is 4,500 hours, the time between overhauls
