Transcatheter closure of large ostium secundum atrial septal defects in symptomatic small children: A single-center retrospective study.

Background: In general, the risks associated with transcatheter atrial septal defect (ASD) device closure are reported to be relatively low, but the evidence stems from trials involving adults and older children. Current guidelines do not recommend ASD device closure in children with defect sizes >20 mm due to limited data available in this group of patients. This retrospective study sought to determine the clinical and procedural characteristics of successful transcatheter ASD device closure in small children with large defects and assess the complication rates and reasons for unsuccessful device closure.

Electrochemical CO Activation and Valorization on Metallic Copper and Carbon-Embedded N-Coordinated Single Metal MNC Catalysts.

The electrochemical reductive valorization of CO, referred to as the CO2RR, is an emerging approach for the conversion of CO-containing feeds into valuable carbonaceous fuels and chemicals, with potential contributions to carbon capture and use (CCU) for reducing greenhouse gas emissions. Copper surfaces and graphene-embedded, N-coordinated single metal atom (MNC) catalysts exhibit distinctive reactivity, attracting attention as efficient electrocatalysts for CO2RR. This review offers a comparative analysis of CO2RR on copper surfaces and MNC catalysts, highlighting their unique characteristics in terms of CO activation, C/C product formation, and the competing hydrogen evolution pathway.

Distortion-Induced Interfacial Charge Transfer at Single Cobalt Atom Secured on Ordered Intermetallic Surface Enhances Pure Oxygen Production.

In this work, atomic cobalt (Co) incorporation into the PdGe intermetallic lattice facilitates generation of a thin layer of CoO over Co-substituted PdGe, with Co in the CoO surface layer functioning as single metal sites. Hence the catalyst has been titled Co-CoO-PdGe. High-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray absorption spectroscopy confirm the existence of CoO, with some of the Co bonded to Ge by substitution of Pd sites in the PdGe lattice.

All protein-coding genes (PCGs) initiated with a canonical ATN codon and ended with TAN or an incomplete stop codon, single T.

Selective Metal-Free CO Photoreduction in Water Using Porous Nanostructures with Internal Molecular Free Volume.

The conversion of CO to a sole carbonaceous product using photocatalysis is a sustainable solution for alleviating the increasing levels of CO emissions and reducing our dependence on nonrenewable resources such as fossil fuels. However, developing a photoactive, metal-free catalyst that is highly selective and efficient in the CO reduction reaction (CORR) without the need for sacrificial agents, cocatalysts, and photosensitizers is challenging. Furthermore, due to the poor solubility of CO in water and the kinetically and thermodynamically favored hydrogen evolution reaction (HER), designing a highly selective photocatalyst is challenging.

Wurtzite CuGaS with an In-Situ-Formed CuO Layer Photocatalyzes CO Conversion to Ethylene with High Selectivity.

We present surface reconstruction-induced C-C coupling whereby CO is converted into ethylene. The wurtzite phase of CuGaS undergoes in situ surface reconstruction, leading to the formation of a thin CuO layer over the pristine catalyst, which facilitates selective conversion of CO to ethylene (C H ). Upon illumination, the catalyst efficiently converts CO to C H with 75.

Intrinsic Charge Polarization in Bi S Cl Nanorods Promotes Selective CC Coupling Reaction during Photoreduction of CO to Ethanol.

Obtaining multi-carbon products via CO  photoreduction is a major catalytic challenge involving multielectron-mediated CC bond formation. Complex design of multicomponent interfaces that are exploited to achieve this chemical transformation, often leads to untraceable deleterious changes in the interfacial chemical environment affecting CO  conversion efficiency and product selectivity. Alternatively, robust metal centers having asymmetric charge distribution can effectuate CC coupling reaction through the stabilization of intermediates, for desired product selectivity.

Detection and Management of Giant Submandibular Gland Sialolith.

Sialolithiasis is a disease process involving the formation of conglomerates of calcifications in the ductal system or the parenchyma of the salivary gland. The Submandibular gland is more vulnerable to form sialoliths than the other major salivary glands due to its salivary composition and anatomic factors. The management of sialolithiasis is determined by the dimensions and position of the calculi.
