Synergistic interfacial electronic modulation of topotactically developed bimetallic CoNiP on NiS nanorods for enhanced alkaline hydrogen evolution reaction.

Designing hybrid transition metal phosphosulfide electrocatalysts is critical for the hydrogen evolution reaction (HER). We propose a novel approach by designing a hierarchical structure of cobalt phosphide (CoP) and nickel phosphide (NiP) nanoparticles topotactically developed on nickel sulfide (NiS) nanorods (CoNiP/NiS) a sulfuration-phosphorization strategy using conductive 3D nickel foam. Hierarchical heterostructured nanorods were achieved without the need for template removal steps or the assistance of surfactants.

Nickel-Iron Layered Double Hydroxides/Nickel Sulfide Heterostructured Electrocatalysts on Surface-Modified Ti Foam for the Oxygen Evolution Reaction.

Electrochemical approaches for generating hydrogen from water splitting can be more promising if the challenges in the anodic oxygen evolution reaction (OER) can be harnessed. The interface heterostructure materials offer strong electronic coupling and appropriate charge transport at the interface regions, promoting accessible active sites to prompt kinetics and optimize the adsorption-desorption of active species. Herein, we have designed an efficient multi-interface-engineered NiFe LDH/NiS/TW heterostructure on in situ generated titanate web layers from the titanium foam.

Endovascular approach to a complex thrombus in-transit through a patent foramen ovale.

Unlabelled: Large atrial thrombi can be managed percutaneously. We present a case of a 76-year-old female patient who presented to our emergency room with an acute stroke and was managed with mechanical thrombectomy. Further work-up revealed a large complex thrombus in-transit trapped in a patent foramen ovale with a large mobile portion in the left atrium.

Perioperative Coagulation Management in Liver Transplant Recipients.

We review contemporary coagulation management for patients undergoing liver transplantation. A better understanding of the complex physiologic changes that occur in patients with end-stage liver disease has resulted in significant advances in anesthetic and coagulation management. A group of internationally recognized experts have critically evaluated current approaches for coagulopathy detection and management.

A prospective randomized pilot study of near-infrared spectroscopy-directed restricted fluid therapy versus standard fluid therapy in patients undergoing elective colorectal surgery.

There are substantial data supporting the concept that algorithms that effectively limit fluid volumes to patients undergoing elective surgery, particularly intraoperatively, significantly reduce perioperative morbidity. We hypothesized that intraoperative fluid limitation could be safely accomplished when guided by near-infrared spectroscopy (NIRS) monitoring, and that this fluid restriction regimen would result in a reduction in postoperative morbidity when compared with standard monitoring and fluid therapy. The intent of this pilot study was to demonstrate the feasibility and ease of conduct of this study protocol before expanding to the multicenter pivotal trial.
