Yarn tension model and vibration analysis during unwinding of carbon fiber bobbins
Journal of Industrial Textiles, 2023 A low-quality unwinding process of the unwinding machine can lead to downtime of the knitting machine and loss of fabric quality. To address this issue, we studied the tension and vibration of carbon fiber yarns during unwinding.

DNA Unwinding Driven by Gold Nanoparticles [PDF]
NanomaterialsWe demonstrate that gold nanoparticles (AuNPs) are capable of unwinding double-stranded (ds) DNA. Upon unwinding, the exposed nucleobases of the separated strands adsorb onto the nanoparticle surface, resulting in the coating of the particles.

The ribosome derives the energy to translocate and unwind mRNA from EF-G binding [PDF]
Nature CommunicationsThe GTPase EF-G catalyzes translocation of mRNA and tRNAs relative to the ribosome and helps maintain the reading frame during protein synthesis. Which events directly require EF-G-mediated GTP hydrolysis during translocation are still debated.
