The intrinsic properties of vertically aligned graphene (VG), such as a high ratio exposed active edge sites compared to inert basal sites, non-stacking morphology and large surface-to-volume make it applicable numerous advanced technologies sensors, flexible electronics fuel cells. Plasma-enhanced chemical vapour deposition has emerged promising technique synthesise at lower temperatures than ...

Background: A growing number of patients with End-Stage Renal Disease (ESRD) are undergoing long-term hemodialysis (HD).  HD needs a vascular access (VA) and complications of VA account for a sizable proportion of its costs. One of the important cardiovascular diseases (CVD) is atherosclerosis, which is a major cause of premature deaths in the world. So, it is essential to find the risk fa...

Multi-layered polycrystalline diamond (PCD) films were synthesized using microwave plasma-assisted chemical vapor deposition (CVD) with periodical addition (injections) of N 2 gas to the standard CH 4 -H mixture. The aim such an approach was reduce roughness while preserving overall high quality and phase purity PCD material. thicknesses in range 5 51 ?m, number layers from 1 15. introduction e...

The fabrication of graphene devices can be challenging due to exposure to harsh chemicals and mechanical wear such as ultrasonication used for cleaning in photolithography and metal deposition. Common graphene processing methods often damage fragile graphene sheets and can ruin the device during fabrication. The authors report a facile method to overcome many of these challenges, which is speci...
