A Zeolitic Octahedral Metal Oxide with Ultra-Microporosity for Inverse CO /C H Separation at High Temperature and Humidity.

Separation of CO /C H to obtain pure C H presents a challenge for the chemical industry. CO -selective adsorbents are favored because of the convenient separation process. However, there are only a few CO -selective adsorbents that can effectively isolate CO from CO /C H , and there is almost no research on CO /C H separation under harsh conditions, such as with high temperatures and humidities.

Single-Atom-Thick Active Layers Realized in Nanolaminated Ti(AlCu)C and Its Artificial Enzyme Behavior.

A Ti(AlCu)C phase with Cu atoms with a degree of ordering in the A plane is synthesized through the A site replacement reaction in CuCl molten salt. The weakly bonded single-atom-thick Cu layers in a Ti(AlCu)C MAX phase provide actives sites for catalysis chemistry. As-synthesized Ti(AlCu)C presents unusual peroxidase-like catalytic activity similar to that of natural enzymes.

Direct, selective and ultrasensitive electrochemical biosensing of methyl parathion in vegetables using Burkholderia cepacia lipase@MOF nanofibers-based biosensor.

Methyl parathion is one of the most widely used pesticides in agricultural practices. It caused accumulation of acetylcholine and over-stimulation of receptors in synapses which eventually led to damage of the nervous system. Present study developed a direct, sensitive, rapid and reliable method for methyl parathion residues detection in vegetable samples.

Fingerprinting of Phospholipid Molecular Species from Human Milk and Infant Formula Using HILIC-ESI-IT-TOF-MS and Discriminatory Analysis by Principal Component Analysis.

Phospholipid composition in the milk fat globule membrane (MFGM) fluctuates during the entire lactation period in order to suit the growing needs of newborn infants. The present study elucidated and relatively quantified phospholipid molecular species extracted from human milk (HM), mature human milk (MHM), and infant formulas (with or without MFGM supplementation) using hydrophilic liquid chromatography-electrospray ionization-ion trap-time of flight-mass spectrometry (HILIC-ESI-IT-TOF-MS) system. Principal component analysis was used to clarify the differences between phospholipid composition in HM, MHM, and infant formulas.
