N as an Efficient IR Probe Molecule for the Investigation of Ceria-Containing Materials.

Ceria and ceria-based catalysts are very important in redox and acid-base catalysis. Nanoceria have also been found to be important in biomedical applications. To design efficient materials, it is necessary to thoroughly understand the surface chemistry of ceria, and one of the techniques that provides such information about the surface is the vibrational spectroscopy of probe molecules.

Capturing CO by ceria and ceria-zirconia nanomaterials of different origin.

Ceria and ceria-zirconia nanomaterials of different origin were studied in order to elucidate the role of their structural and textural characteristics in controlling the performance towards CO capture. Two commercial cerias and two home-prepared samples, CeO and CeO-ZrO (75% CeO) mixed oxide, were investigated. The samples were characterized by a number of analytical techniques including XRD, TEM, N-adsorption, XPS, H-TPR, Raman and FTIR spectroscopy.

One Ca Site in CaNaY Zeolite Can Attach Three CO Molecules.

To design efficient CO capture materials, it is necessary to ensure a high adsorption capacity. We recently reported that one Na site in NaY zeolite can attach two CO molecules. However, the process is not suitable for practical use because it proceeds at a low temperature.

Complete, Rapid Resolution of Severe Bilateral Pneumonia and Acute Respiratory Distress Syndrome in a COVID-19 Patient: Role for a Unique Therapeutic Combination of Inhalations With Bromhexine, Higher Doses of Colchicine, and Hymecromone.

An otherwise healthy, 35-year-old man was hospitalized for the management of acute respiratory failure due to coronavirus disease 2019 (COVID-19)-related severe bilateral pneumonia and acute respiratory distress syndrome (ARDS). The patient therapeutic regimen included the widely accepted standard combination of oxygen, anticoagulation therapy; corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), and antibiotics. A novel combination of colchicine, hymecromone, and bromhexine inhalations was added to the therapeutic regimen as part of our unique COVID-19 management institutional protocol.

Effect of calcium on enhanced carbon capture potential of coal fly ash zeolites. Part II: a study on the adsorption mechanisms.

Coal fly ash zeolites (CFAZs) of type X with low (Na-X) and medium (Na-Ca-X) content of calcium were synthesized by alkaline conversion of lignite coal fly ash generated by combustion of lignite with lower and higher limestone amounts, extracted from different coal deposits and burned in separate thermal power plants. The concentration and state of Ca in the zeolites were investigated by energy dispersive X-ray (EDX) analysis and X-ray photoelectron spectroscopy (XPS). CFAZs Na-Ca-X with a medium Ca-content were found to outperform their lower calcium counterparts Na-X in terms of carbon capture capacity.
