This paper initially discussed synthesis and modification of tetrafunctional epoxy resin(1,1,2,2- tetrakis(hydroxy phenye)ethane),as well as application in copper clad laminate.
Four new materials,such as carbon suspension,sodium sulfonate of polyoxyethylene allyl glycidyl nonyl phenyl ether,vanillyl alcohol,vanillin,etc,in lead-acid storage batteries were reviewed.
OBJECTIVE:To study the adsorption of disposable transfusion connective tube and infusion needle for single use only to nitroglycerin in intravenous injection via minipump.
Overseas research progress of new process for synthesis glycerol from formaldehyde is introduced. Close relationship of the technology yielding with formose technique is reviewed.
Objective To compare the clinical treatment effect and side reaction of dissolving compound salivia miltiorrhiza in mouth and dissolving nitroglycerin in mouth to treat angina pectoris.
Recently, it has been shown that the Mitochondrial aldehyde dehydrogenase is responsible for the bioactivation of nitroglycerin prior to the release of NO, which is a strong vasodilator.
