Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Advantages of Pulsed Laser Ion Source (LIS) at an Intensity of About 1010 W/cm2 for Heavy‐Ion Injection Into High‐Energy Accelerators

Contributions to Plasma Physics, EarlyView.
ABSTRACT At the Laser Plasma Physics laboratories of the University of Messina, an experimental platform for generating and accelerating low‐energy ions (keV) using pulsed lasers and for their potential applications has been put into operation. A Q‐switched Nd:YAG laser produces the beam for the system, operating at 1064 nm.

Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

Drug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Population Pharmacokinetics and Detection Times of Betamethasone After Intravenous, Intramuscular, and Intranasal Jet Administration of Betamethasone Sodium Phosphate in Horses

Drug Testing and Analysis, EarlyView.
Betamethasone concentrations in 20 horses from Japan and Germany following IV, IM, and INJ administration of betamethasone phosphate were analyzed using population pharmacokinetic modeling. For IV administration of 0.04 mg/kg q24 h, IPC and IUC were 0.012 and 0.31 ng/mL, respectively; the IUC approximated the IFHA urine ISL (0.20 ng/mL).
