Dispensability of HPF1 for cellular removal of DNA single-strand breaks. [PDF]

Nucleic Acids Res
In response to DNA damage, the histone PARylation factor 1 (HPF1) regulates PARP1/2 activity, facilitating serine ADP-ribosylation of chromatin-associated factors.

Influence of storage time and amplitude sweeps on flocculation behavior in silica-filled SSBR compounds [PDF]

Discover Polymers
The Payne effect reflects the breakdown of filler-filler networks in rubber compounds, particularly in silica-filled systems. However, during storage, time-dependent flocculation of silica clusters leads to an increase in storage modulus, thereby ...

“Re-Think” Sulfur Curing [PDF]

Molecules
Since Charles Goodyear discovered the method of sulfur curing Natural Rubber in 1839, many studies have been carried out to understand its mechanism. Currently, the broadly accepted mechanism includes an activated accelerator complex formed by Zinc oxide,

Mechanisms of DNA Damage Recognition by UDG and PARP1 in the Nucleosome [PDF]

Biomolecules
The DNA base-excision repair (BER) pathway shares the second part of its enzymatic chain with the single-strand break (SSB) repair pathway. BER is initiated by a glycosylase, such as UDG, while SSBR is initiated by the multifunctional enzyme PARP1.

Investigation of different ingredients contributing to the cure torque in silica-filled SSBR compounds [PDF]

, 2023
Chemical crosslinking of elastomers through the vulcanization process creates a three-dimensional network and makes them suitable for many engineering applications. During this reaction, the polymer chains are linked to each other in presence of curing agents.

Study on the influence of carbon nanotubes bundles on the electrical conductivity and mechanical properties of SSBR

Journal of Physics: Conference Series
Abstract This study investigates the impact of carbon nanotube bundles (CNTBs) on the static and dynamic mechanical properties and the electrical conductivity of Soluble Styrene Butadiene Rubber (SSBR) composites. The results show that the CNTBs employed exhibit excellent orientation and dispersion within the rubber matrix.
