Genetic investigation of hydrogenases in suggests that redox balance via hydrogen cycling enables high ethanol yield.

Unlabelled: is an anaerobic and thermophilic bacterium that has been genetically engineered for ethanol production at very high yields. However, the underlying reactions responsible for electron flow, redox equilibrium, and how they relate to ethanol production in this microbe are not fully elucidated. Therefore, we performed a series of genetic manipulations to investigate the contribution of hydrogenase genes to high ethanol yield, generating evidence for the importance of hydrogen-reacting enzymes in ethanol production.

Partial PdAu nanoparticle embedding into TiO support accentuates catalytic contributions from the Au/TiO interface.

Despite the broad catalytic relevance of metal-support interfaces, controlling their chemical nature, the interfacial contact perimeter (exposed to reactants), and consequently, their contributions to overall catalytic reactivity, remains challenging, as the nanoparticle and support characteristics are interdependent when catalysts are prepared by impregnation. Here, we decoupled both characteristics by using a raspberry-colloid-templating strategy that yields partially embedded PdAu nanoparticles within well-defined SiO or TiO supports, thereby increasing the metal-support interfacial contact compared to nonembedded catalysts that we prepared by attaching the same nanoparticles onto support surfaces. Between nonembedded PdAu/SiO and PdAu/TiO, we identified a support effect resulting in a 1.

Computational Design of Catalysts with Experimental Validation: Recent Successes, Effective Strategies, and Pitfalls.

Computation has long proven useful in understanding heterogeneous catalysts and rationalizing experimental findings. However, computational design with experimental validation requires somewhat different approaches and has proven more difficult. In recent years, there have been increasing successes in such computational design with experimental validation.

Reprint of: Implementation and perception of outpatient pharmacists prescribing hormonal contraceptives in North Carolina.

Background: North Carolina (NC) House Bill 96, effective February 2022, enabled trained immunizing pharmacists across the state to prescribe hormonal contraceptives (HCs). However, the extent and barriers to deployment are unknown. The purpose of this study was to describe the uptake and challenges from outpatient pharmacists who trained to provide HCs in an outpatient practice to assist others in the implementation of this service.

Improving healthcare professionals' ultrasound-guided peripheral vascular access ability utilizing self-assembled ultrasound phantoms: A prospective, observational quality improvement project.

Background: Ultrasound guidance can reduce the number of attempts to gain peripheral IV access while improving the success rate and satisfaction in patients with difficult IV access. Education and simulation are effective tools for improving the skills and knowledge related to ultrasound-guided peripheral IV access. Ultrasound phantom models allow for skill development without the risk of patient harm.
