Abstract:
A method of treating a surface of a substrate using modified urushiol derived from Toxicodendron vernicifluum is provided. More particularly, the reactivity of a hydroxyl group of urushiol extracted from fresh Toxicodendron vernicifluum is removed before the lacquer is used as a UV coating agent for a substrate such as a steel sheet. Therefore, the substrate may have high antibacterial activity, and excellent appearance and functionalities such as far-infrared radiation, blocking of electromagnetic waves, enhanced corrosion resistance, high crosslinking speed when a low content of a photoinitiator is used, excellent surface gloss and high scratch resistance.

A radiation-curable base resin composition and a fingerprint-resistant resin composition including the same are provided. The radiation-curable base resin composition includes a multifunctional urethane (meth)acrylate having three or more functional groups at 3 to 35 parts by weight, a bifunctional urethane (meth)acrylate at 3 to 35 parts by weight, at least one (meth)acrylic acid ester monomer selected from a monofunctional (meth)acrylic acid ester monomer and a multifunctional (meth)acrylic acid ester monomer at 20 to 60 parts by weight and a radiation polymerization initiator at 0.1 to 15 parts by weight.
Abstract:
A pH adjusting apparatus includes an electrolytic chip receiving a solution, an electrolytic chip loading station receiving the electrolytic chip, an input unit inputting electrolysis conditions, a control unit receiving the electrolysis conditions and controlling electrolysis performed in the electrolytic chip, and a display unit displaying the electrolysis conditions and a progress of the electrolysis. Thus, the pH of a solution can be adjusted easily and accurately, by precisely controlling a constant current, a constant voltage, and current and voltage application times, thereby enabling useful application in various biological assays such as cell lysis. Furthermore, the pH adjusting apparatus has small size and weight and can be operated for a long time after charging once due to low power consumption.
Abstract:
Provided are a pointing apparatus capable of providing haptic feedback, and a haptic interaction system and method using the same. The pointing apparatus includes a wireless communication unit, a controller, and a haptic stimulator. The wireless communication unit receives an event including haptic output information through wireless communication with the outside. The controller generates a control signal for reproducing a haptic pattern corresponding to the haptic output information. The haptic stimulator reproduces the haptic pattern by means of the control signal. Thus, it is possible to increase the performance and usability of a user interface of a user terminal including a touch screen.
