Application of Surfactants to Improvement of Viscose Processability of Sulphate Dissolving Pulp (II)
Mass production of high-quality graphene with low cost is the footstone for its widespread practical applications. We present herein a self-limited growth approach for producing graphene powders by a small-methane-flow chemical vapour deposition process on naturally abundant and industrially widely used diatomite (biosilica) substrates. Distinct from the chemically exfoliated graphene, thus-pro...
Dual amide hydrogen bond crosslinked and strengthened high strength supramolecular polymer conductive hydrogels were fabricated by simply in situ doping poly (N-acryloyl glycinamide-co-2-acrylamide-2-methylpropanesulfonic) (PNAGA-PAMPS) hydrogels with PEDOT/PSS. The nonswellable conductive hydrogels in PBS demonstrated high mechanical performances-0.22-0.58 MPa tensile strength, 1.02-7.62 MPa c...
Additive manufacturing (AM) of customised vascular or peripheral stents is great potential for surgeons and patients, enabling the patients to have achieving better outcomes from stenting procedures, with further advantages having a resource efficient process. In this study, AM superelastic NiTi-based shape memory alloy (Nitinol) was investigated. Two stent designs, which are used treatment com...
Laser powder bed fusion (L-PBF) is one of the most promising additive manufacturing (AM) methods which provides an exceptional opportunity to improve existing designs and move toward fabricating fine features complex geometries with higher efficiencies. Considering layer-wise nature this technique, possibility tied ability deposit thin layers in process. Since layer thickness directly dictated ...
thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...
Abstract The aerospace industry makes extensive use of composite materials in the form fibre fabrics pre-impregnated with thermosetting resin, called prepregs. In order to minimize resin polymerization before curing, prepregs must be stored at -18°C (0°F). There are therefore expiration dates for use. Although manufacturers try storage time, offcuts and time out freezer, it is estimated that 30...
