This study examined the extent of organic solvent and water retention in comonomer blends with different hydrophilicity (Hoy’s solubility parameter for hydrogen bonding, δh) after solvent evaporation, and the extent of tracer penetration in polymerised films prepared from these resins. For each comonomer blend, adhesive/solvent mixtures were prepared by addition of [1] 50wt% acetone; [2] 50wt% ...

Anodizing a simple and effective method to improve the wear resistance of 6061 aluminum alloy. In this study, microstructure alloy oxide films (AAO) was adjusted by changing electrolyte temperature (5, 15, 25 °C) using 160 g/L sulfuric acid as electrolyte. The phase composition, microstructure, morphological characteristics specimens were detected X-ray diffractometer field emission scanning el...

conclusions algino-pectinate mucoadhesive formulations exhibited promising properties of a sustained release form for piroxicam and provided distinct tissue protection in stomach. objective the purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. materials and methods ionotropic gelation was us...

Abstract Diamond-like carbon (DLC) films directly deposited on rubber substrate is undoubtedly one optimal option to improve the tribological properties due its ultralow friction, high-hardness as well good chemical compatibility with rubber. Investigating relationship between film structure and performance vital for protecting In this study it was demonstrated that etching effect induced by hy...

The defects of polyester films used for glass curtain walls, such as discoloration, peeling, and wrinkling, are thought to be caused by degradation. This occurs in a short period (approximately 1/10) the conventional service lifetime. A comprehensive investigation demonstrated that extremely low ultraviolet (UV) absorber (2,2’,4,4’-tetrahydroxybenzophenone) content adhesive coating defects, ins...

Conventional industrial grippers that grip a flat object generally hold objects by using suction or electrostatic force. However, these have limitations when gripping thin, flat, and flexible objects, such as films printed circuit boards (FPCBs), due to their undefined shape high flexibility. This paper proposes soft gripper can thin utilizing directional adhesives compliant mechanism. The adhe...
