Can the adenosine triphosphate (ATP) bioluminescence assay be used as an indicator for hospital cleaning? - A pilot study.

Background: In hospital cleaning, there is currently no standard for uniform monitoring of surface cleaning, either in Germany or internationally. One possibility for monitoring is the use of so-called objective methods for checking cleaning performance (e.g.

Stigma, Post-traumatic Stress, and COVID-19 Vaccination Intent in Mongolia, India, and the United States.

: Stigma and discrimination during the coronavirus (COVID-19) pandemic have increased precipitously worldwide. This multinational study examines how stigma, blaming groups for virus spread, concern regarding contracting the virus, resource loss, life satisfaction, and protective behaviors that help control the spread of COVID-19 are associated with post-traumatic stress and vaccine intent in Mongolia, India, and the United States. : 1429 people in Mongolia, India, and the United States completed measures assessing stigma during the COVID-19 pandemic, post-traumatic stress, blame, protective behaviors, and vaccine intent.

Zirconium-Catalyzed C-H Alumination of Polyolefins, Paraffins, and Methane.

C-H/Et-Al exchange in zirconium-catalyzed reactions of saturated hydrocarbons and AlEt affords versatile organoaluminum compounds and ethane. The grafting of commercially available Zr(OBu) on silica/alumina gives monopodal ≡SiO-Zr(OBu) surface pre-catalyst sites that are activated in situ by ligand exchange with AlEt. The catalytic C-H alumination of dodecane at 150 °C followed by quenching in air affords -dodecanol as the major product, revealing selectivity for methyl group activation.

Size-Controlled Nanoparticles Embedded in a Mesoporous Architecture Leading to Efficient and Selective Hydrogenolysis of Polyolefins.

A catalytic architecture, comprising a mesoporous silica shell surrounding platinum nanoparticles (NPs) supported on a solid silica sphere (mSiO/Pt-/SiO; is the mean NP diameter), catalyzes hydrogenolysis of melt-phase polyethylene (PE) into a narrow C-centered distribution of hydrocarbons in high yield using very low Pt loadings (∼10 g Pt/g PE). During catalysis, a polymer chain enters a pore and contacts a Pt NP where the C-C bond cleavage occurs and then the smaller fragment exits the pore. mSiO/Pt/SiO resists sintering or leaching of Pt and provides high yields of liquids; however, many structural and chemical effects on catalysis are not yet resolved.

Scalable Synthesis of Pt/SrTiO Hydrogenolysis Catalysts in Pursuit of Manufacturing-Relevant Waste Plastic Solutions.

An improved hydrothermal synthesis of shape-controlled, size-controlled 60 nm SrTiO nanocuboid (STO NC) supports, which facilitates the scalable creation of platinum nanoparticle catalysts supported on STO (Pt/STO) for the chemical conversion of waste polyolefins, is reported herein. This synthetic method (1) establishes that STO nucleation prior to the hydrothermal treatment favors nanocuboid formation, (2) produces STO NC supports with average sizes ranging from 25 to 80 nm with narrow size distributions, and (3) demonstrates how SrCO formation and variation in solution pH prevent the formation of STO NCs. The STO synthesis was scaled-up and conducted in a 4 L batch reactor, resulting in STO NCs of comparable size and morphology ( = 22.
