Effective Nitrate Electroconversion to Ammonia Using an Entangled CoO/Graphene Nanoribbon Catalyst.

There has been huge interest among chemical scientists in the electrochemical reduction of nitrate (NO) to ammonia (NH) due to the useful application of NH in nitrogen fertilizers and fuel. To conduct such a complex reduction reaction, which involves eight electrons and eight protons, one needs to develop high-performance (and stable) electrocatalysts that favor the formation of reaction intermediates that are selective toward ammonia production. In the present study, we developed and applied CoO/graphene nanoribbon (GNR) electrocatalysts with excellent properties for the effective reduction of NO to NH, where NH yield rate of 42.

Satisfaction and Workload as Predictors of Psychological Distress in Professionals of Psychosocial Care Centers During the COVID-19 Pandemic.

Background And Aims: The COVID-19 pandemic significantly impacted the mental health of healthcare professionals, especially those working in Psychosocial Care Centers (CAPS), which are crucial services in the Brazilian mental health system. This study aimed to investigate the association between job satisfaction, workload, and psychological distress among CAPS professionals during the pandemic.

Methods: A cross-sectional study was conducted with 53 professionals from seven CAPS.

Tunneling and conformational preferences in racemic- and meso-2,4-pentanediol: A rotational spectroscopic and theoretical investigation.

The rotational spectra of a mixture of 2,4-pentanediol (PDL) isomers, comprising both the meso isomers [(2R, 4S) and (2S, 4R)] and the racemic isomers [(2R, 4R) and (2S, 4S)], were recorded using a chirped-pulse Fourier transform microwave spectrometer coupled to a supersonic jet expansion. The conformational landscapes of meso- and racemic-PDL were examined using the Conformer-Rotamer Ensemble Sampling Tool and high-level quantum chemical calculations, generating 26 and 25 conformers, respectively. Five sets of rotational transitions were observed and assigned, with two attributed to meso-PDL and the remaining three attributed to racemic-PDL.

Effect of monensin and essential oil blend supplementation on lactation performance and feeding behavior by dairy cows.

The objective of this study was to evaluate the effects of supplementing an essential oil blend (0.16 g/kg DM of carvacrol, eugenol, thymol, and capsaicin) and monensin (17.6 mg/kg DM TMR) on lactation performance, feeding behavior, and rumen fermentation of high-producing dairy cows.

Incidence of hepatobiliary malignancies in primary sclerosing cholangitis: systematic review and meta-analysis.

Background And Aims: Primary sclerosing cholangitis (PSC) is a known risk factor for hepatobiliary malignancies. We conducted a systematic review and meta-analysis of published studies to determine the incidence and risk factors for hepatobiliary malignancies in people with PSC.

Methods: Pubmed and Embase databases were searched from inception to April 10, 2024 for cohort studies reporting data on the incidence of cholangiocarcinoma (CCA), hepatocellular carcinoma (HCC), or gallbladder cancer (GBC) in PSC.
