Article Abstract
An N-heterocyclic stannylene :Sn(NON) (NON = [O(SiMeNAd)], Ad = 1-adamantyl), reacts rapidly with 2,4,6-tricyclohexylphenyl azide (TCHP)N, affording a stannaimine, (NON)SnN(TCHP). Solutions of (NON)SnN(TCHP) react immediately with carbon dioxide (CO) to give a [2+2]-cycloaddition product, which, upon heating, subsequently engages in a metathesis process to give [Sn(NON)(μ-O)] and the bulky isocyanate, (TCHP)NCO.

Advances in the direct conversion of CH and CO into acetic acid over bimetallic catalysts supported on H-ZSM-5.
Nanoscale Horiz

Department of Physical Chemistry, São Carlos Institute of Chemistry, University of São Paulo, Brazil.
This study developed heterogeneous catalysts composed of ZnO and CeO supported on H-ZSM-5 for the direct conversion of methane (CH) and carbon dioxide (CO) into acetic acid. The acid-base and electronic properties were modulated through oxide impregnation and reduction, aiming to create active sites capable of simultaneously activating both reactants. The samples were characterized by XRD, N physisorption, HRTEM/EDS, NH-TPD, CO-TPD, TPR, FTIR, XPS, CO-DRIFTS, and TGA, and tested in a batch reactor at 300 °C and 10 bar.

2D Bismuth oxycarbonate (2D BOC) nanosheets have a unique layered structure with many applications, including capture and reduction of carbon dioxide. Processing powdered elemental bismuth in water under ambient air conditions using a vortex fluidic device (VFD) results in the formation of 2D BOC without the need of surfactants or other excipients. The induced high shear mechanical energy in the form of micron/submicron topological typhoon like spinning top (ST) fluid flow drives the conversion, which we propose initially melts the metal particles which are spontaneously oxidised at the liquid-quartz tube interface to form 2D bismuth oxide (BiO).

Background: The relationship between intraoperative end-tidal CO (etCO) levels and postoperative outcomes remains unclear. We conducted a post hoc analysis of two randomised trials in adults undergoing major surgery under general anaesthesia.
Methods: We re-analysed individual participant data comparing high or low positive end-expiratory pressure with low tidal volume intraoperative ventilation using a merged database derived from two randomised trials in non-obese (PROVHILO: ISRCTN70332574) and obese (PROBESE: NCT02148692) patients.
Effects of daily post-training, high-concentration CO-water immersion on thermoregulatory function in young male baseball players.

Among the different forms of hydrotherapy, carbon dioxide (CO) water immersion improves peripheral vasodilation and blood flow compared with tap water immersion; however, the heat stress placed on the body through CO water immersion and the appropriate immersion protocols are uncertain. Therefore, this study aimed to compare the thermoregulatory responses during CO and tap water immersions. The participants were 10 male college baseball players.

Parvalbumin (PV), a thermostable and digestion-resistant fish allergen, has been shown to retain its allergenic potential following traditional treatments, thus posing a persistent allergic risk. The study investigated the digestive kinetics and IgE immunoreactivity of Trachinotus ovatus PV, a major fish allergen, under different treatments (untreated; DPCD treatment-15 MPa, 30 min, 50 °C; heat treatment), to evaluate its allergenic potential alterations. The analysis was conducted using a combination of techniques to assess the proteolytic stability and IgE-binding capacity of PV, including Tris-Tricine-SDS-PAGE, Western blot (WB), indirect enzyme-linked immunosorbent assay (ELISA), and free amino group quantification.
