The present disclosure pertains to antimicrobial compounds that include silver (Ag) and an s-triazine ring with substitutions at nitrogen or carbon atoms of the s-triazine ring. In one example, the antimicrobial silver s-triazine may be readily incorporated in a variety of compositions and devices in both medical and non-medical settings. In another example, the said compounds may possess broad spectrum antimicrobial activity against bacteria, viruses, fungi and other microbes.
摘要:
A semiconductor device and manufacturing method therefor, provided with the aims of constraining resin burr formation while having good electric connectivity and joining strength, and LED device, provided with the aim of improving adhesion between silicon resin and leads while having good luminescent characteristics. For these purposes, an organic film is formed through self-assembly by functional organic molecules at surface border regions of outer leads of a QFP. The functional organic molecules consist of a first functional group bonding with metals, a principal chain, and a second functional group inducing hardening in thermosetting resins. The principal chain consists of a glycol chain, or else of a glycol chain and one or more among methylene, fluoromethylene, or siloxane chains. The principal chain also preferably includes one or more among a hydroxyl radical, ketone, thioketone, primary amine, secondary amine, and aromatic compounds.
