A resin composition for optical fiber coating according to the present disclosure is a resin composition containing a photopolymerizable compound, a photopolymerization initiator, and surface-treated titanium oxide particles, in which a content of the surface-treated titanium oxide particles is 0.6% by mass or more and less than 25% by mass based on the total amount of the resin composition.
SEQUENTIAL PRESSURIZATION TREATMENT METHOD TO FORM A SILVER-SILICALITE COATED SUBSTRATE
A method of making a silver-silicalite coating on a surface of a stainless-steel substrate is provided. The method includes mixing metakaolin with an aqueous solution of NaOH to form a first mixture. The method further includes mixing silica gel and silver nitrate with the first mixture to form a second mixture. Furthermore, the method includes mixing Zeolites Socony Mobil-5 (ZSM-5) with the second mixture to form a third mixture. The method further includes hydrothermally treating the stainless-steel substrate with the third mixture to form the silver-silicalite coating on the surface of the stainless-steel substrate. The hydrothermal treatment is carried out in the absence of an organic template. The stainless-steel substrate coated with the silver-silicalite coating, prepared by the method of the present disclosure, has lower corrosion in comparison to the same stainless-steel substrate without the silver-silicalite coating.

The coating solution contains an acrylic resin having a glass transition point (Tg) of 100 C. or higher and an acid value-to-glass transition point ratio R=acid value (mg-KOH/g)/Tg ( C.) of 1.50 or more, and a polyolefin wax having a melting point of 100 C. or higher and 145 C. or lower and an average particle diameter of 3.0 m or less and is applied to a metal sheet.
QUANTUM DOT COMPOSITE MICROSPHERES, QUANTUM DOT COMPOSITE MICROSPHERE FILMS AND PREPARATION METHOD THEREOF
Disclosed are quantum dot composite microspheres, quantum dot composite microsphere film and preparation method thereof. The quantum dot composite microsphere includes a core, a quantum dot layer adsorbed on a surface of the core, and an outer shell layer coated on the surface of the quantum dot layer, wherein one or more polymer ligands with an ionizable end group are attached to the surface of the outer shell layer. One or more polymer ligands with ionizable end groups are disposed on an outer shell layer of quantum dot composite microspheres. After the quantum dot composite microspheres are dissolved in a solvent, the quantum dot composite microspheres are charged positively or negatively, so that quantum dot composite microspheres are deposited on a positive electrode and a negative electrode during an electrodeposition process, thereby obtaining quantum dot composite microsphere film containing the such quantum dot composite microspheres.
SINTERABLE METAL PASTE FOR USE IN ADDITIVE MANUFACTURING
A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique with high rate and resolution of metal part production due to a hybrid deposition/removal process.
