General description
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
Application
Diethyl sulfite (DES) is used as a film forming and high temperature additive for electrolytes in lithium ion batteries. It improves decomposition resistance of the electrolyte. Diethyl sulfite is also used as solvent for lithium bis(oxalato)borate (LiBOB) based electrolytes. The LiBOB-based electrolyte with DES shows high oxidation potentials, and good conductivities.

Defining the optimal conduction of percutaneous-coronary-intervention (PCI) to treat bifurcation lesions has been the subject of many clinical studies showing that the applied stenting technique may influence clinical outcome. Accordingly, bifurcation stenting classifications and technical sequences should be standardized to

This study sought to explore the association between biomarker elevation, with creatine kinase-myocardial band (CK-MB) or cardiac troponin (cTn), following percutaneous coronary intervention (PCI) and mortality in patients undergoing PCI for stable angina with normal baseline values. Several studies have

Background Acute complete occlusion of a coronary artery results in progressive ischemia, moving from the endocardium to the epicardium (ie, wavefront). Dependent on time to reperfusion and collateral flow, myocardial infarction ( MI ) will manifest, with transmural MI portending
