Thermal properties of composite two-layer systems with a fractal inclusion structure [PDF]

open access: yesJ. Phys. D: Appl. Phys. 48 (2015) 015310, 2014
In this work, we study the thermal transport properties of platelike composite two-layer samples made of polyester resin and magnetite inclusions. By means of photoacoustic spectroscopy and thermal relaxation, their effective thermal diffusivity and conductivity were experimentally measured.

The role of expansion angle and speed on shish-kebab formation in expansion pipe extruder head explored by high temperature rapid stretch

open access: yesPolymer Testing, 2021
Morphology and microstructures play a significant role on properties of polymer products. Self-reinforced shish-kebab formed inside the products by elongational flow induced orientation can improve the tensile strength and pressure rating properties, and

Ultra-ductile and low friction epoxy matrix composites [PDF]

open access: yes, 2014
We present the results of an effective reinforcement of epoxy resin matrix with fullerene carbon soot. The optimal carbon soot addition of 1 wt. % results in a toughness improvement of almost 20 times. The optimized soot-epoxy composites also show an increase in tensile elongation of more than 13 %, thus indicating a change of the failure mechanism in ...

Refining the NaV1.7 pharmacophore of a class of venom‐derived peptide inhibitors via a combination of in silico screening and rational engineering

open access: yesFEBS Letters, EarlyView.
Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Identification of novel small molecule inhibitors of ETS transcription factors

open access: yesFEBS Letters, EarlyView.
ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six
