Microfluidic electro‐viscoelastic manipulation of extracellular vesicles

open access: yesFEBS Open Bio, EarlyView.
The electro‐viscoelastic manipulation as a potential method for separation of particles based on size. The particles introduced as a sheath flow migrate to the channel center under the influence of simultaneously applied electric field and pressure driven flow.

Decomposition and segregation phenomena in PVD TiBN coatings

open access: yesMaterials & Design
TiBN coatings synthesized via physical vapor deposition (PVD) with a B content of 8 at.% and 25 at.% were investigated in terms of their phase and thermal stability, nanoscale composition and mechanical properties, using both experimental and theoretical

Non-uniform sampling finite-time control for networked control systems via event-driven transmission

open access: yesAdvances in Mechanical Engineering, 2016
This article investigates the networked finite-time control problem for a class of continuous-time linear systems. A novel event-driven data transmission scheme is invoked to reduce the network loads.

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 ...

Long‐term culture of skin biopsies: maintenance of fibroblast production and competency of reprogramming

open access: yesFEBS Open Bio, EarlyView.
Skin biopsies taken from a patient with an ultra‐rare disorder as well as controls were cultured for up to 473 days. The chunks of skin were serially transferred to a new culture plate when confluent with fibroblasts. Different generations of fibroblasts were analyzed for cell and molecular properties, proliferation, and competence for reprogramming to
