Abstract: A high-entropy alloy film, the composition of which includes titanium, zirconium, niobium, tantalum and iron. The high-entropy alloy film is made with a combination of elements with high biocompatibility, and its formation of non-crystalline structure is further improved by adding iron. Furthermore, as the content of titanium in the high-entropy alloy film is adjusted, the microstructure, mechanical properties, and corrosion resistance of the high-entropy alloy film is changed as well.

Abstract: A method for physical vapor deposition of an aluminum nitride film, comprising: positioning a substrate and an aluminum target in a chamber; vacuuming the chamber so that a chamber pressure is at a base pressure between 7.1×10?7-5×10?6 torr; conducting a working gas composed of argon gas and nitrogen gas into the chamber so that the chamber pressure is at a working pressure between 3-7 mtorr; and depositing the aluminum nitride film on the substrate by applying a high power impulse power supply to the aluminum target and applying a direct current bias power supply to the substrate under the working pressure and a substrate temperature between room temperature (25° C.) to 200° C.; wherein a power of the high power impulse power supply is between 500-600 W and a frequency thereof is between 750-1250 Hz, and a bias of the direct current bias power supply is between ?50-0 V.

Abstract: Disclosed herein is a ceramic article with an increased surface roughness. The ceramic article includes a ceramic body having an engagement surface and a composite porous layer disposed on the engagement surface of the ceramic body. The composite porous layer is formed from a material including multiple first ceramic particles and multiple second ceramic particles. The sintering temperature of the first ceramic particle is lower than the melting temperature of the second ceramic particle, and at least some of the second ceramic particles are disperse within the composite porous layer whereby increasing the surface roughness of the ceramic article. Methods for manufacturing such ceramic article are also disclosed.

Abstract: A method for augmentation of a soft tissue in a subject, comprising: introducing to the subject a hydrogel composition comprising a porous bio-absorbable ceramic carrier and a hyaluronic acid gel. The porous bio-absorbable ceramic carrier is made of a material selected from the group comprising hydroxyapatite, ?-tricalcium phosphate, or calcium polyphosphate. The hydrogel composition further comprises a cell positioned in a pore of the porous bio-absorbable ceramic carrier. The hydrogel composition is introduced into the subject in the form of an injection thereby eliminating the need for a surgical procedure.

Abstract: Disclosed is an improved fast dry and extremely durable waterborne, coating composition particularly adapted for use as a traffic paint. The basic waterborne coating for traffic paint is comprised of an aqueous emulsion containing an acrylic film forming polymer, a stabilizing system for the emulsion which is pH sensitive, and mineral pigment. The improvement to the basic water borne coating for traffic paint resides in utilizing a hydrophobic acrylate containing polymer which incorporates from about 0.1 to 5% by weight of an secondary or tertiary amino acrylate and a crosslinkable monomer as components of the hydrophobic polymer. The hydrophobic acrylate containing polymer should contain less than 5 weight percent of hydrophilic monomers.

Abstract: Polyvinyl chloride resins and copolymers thereof are produced containing little or no gel content, commonly referred to as "fisheyes", even after numerous charges to a reaction vessel without cleaning thereof between charges. A primary dispersant system such as a high hydrolyzed polyvinyl acetate and an optional modified cellulose ether is utilized in association with a low hydrolyzed secondary dispersant, for example, polyvinyl acetate, in the reaction vessel such as a polymerizer containing an aromatic inhibitor polymer build-up compound coated on the internal walls thereof. The resin particles produced tend to have a uniform particle size and a high porosity so that plasticizers can readily be incorporated therein. Since contamination buildup on the reaction vessel walls is reduced or prevented, the amount of gel is reduced and production rate is increased since, as noted above, cleaning of the vessels is not required.
