Persistent heavy winter nitrate pollution driven by increased photochemical oxidants in northern China.

Environmental Science and Technology, 2020
Nitrate is an increasingly important component of PM2.5 during winter in northern China. Past emission control has been ineffective in reducing winter nitrate.

Both Fe(IV) and Radicals Are Active Oxidants in the Fe(II)/Peroxydisulfate Process

, 2020
The question of whether Fe(IV) or SO4•– is the dominant intermediate in the Fe(II)-activated peroxydisulfate process [Fe(II)/PDS process] remains unanswered.

Alternative Oxidants for the Catalytic Oxidative Coupling of Methane.

Angewandte Chemie, 2020
The catalytic oxidative coupling of methane (OCM) to C2 hydrocarbons with oxygen (O 2 -OCM) has garnered renewed worldwide interest in the past decade due to the emergence of enormous new shale gas resources.

The Impact of pH and Irradiation Wavelength on the Production of Reactive Oxidants during Chlorine Photolysis.

Environmental Science and Technology, 2019
Chlorine photolysis is an advanced oxidation process which relies on photolytic cleavage of free available chlorine (i.e., hypochlorous acid and hypochlorite) to generate hydroxyl radical, along with ozone and a suite of halogen radicals. Little is known

Oxide-nitride-oxide antifuse reliability

28th Annual Proceedings on Reliability Physics Symposium, 1990
Compact, low-resistance oxide-nitride-oxide (ONO) antifuses are studied for time-dependent dielectric breakdown (TDDB), program disturb, programmed antifuse resistance stability, and effective screen. ONO antifuses are superior to oxide antifuses. No ONO antifuse failures were observed in 1.8 million accelerated burn-in device-hours accumulated on 1108

Lipid-Oxidation-Induced Carboxymyoglobin Oxidation

Journal of Agricultural and Food Chemistry, 2006
We evaluated the usefulness of the ratio A503/A581 as a browning index (BI) for estimating brown color formation in solutions containing oxymyoglobin (OxyMb) and carboxymyoglobin (COMb). In split-chamber cuvette analyses with different proportions of metmyoglobin (MetMb), COMb and OxyMb, BI was highly correlated (r = 0.93-0.94) with direct estimation ...
