Developing highly efficient biomass-derived carbon-based electrocatalysts remains challenging for urea electrolysis because most of these electrocatalysts show powder morphology, which can lead to Ostwald ripening during the reaction process, and its reaction mechanism should be further verified. Herein, self-supported lignin-derived carbon coupling NiO@MoNi heterojunction (NiO@MoNi/C) possesses superhydrophilic properties and electronic modulation, boosting the performance of urea electrolysis. Electrochemical results show that an indirect oxidation step for urea oxidation reaction (UOR) and Volmer-Heyrovsky mechanism for hydrogen evolution reaction (HER) occurs on the surface of NiO@MoNi/C.

- The study examines the role of transesophageal echocardiography (TEE) in enhancing the safety and effectiveness of percutaneous patent foramen ovale (PFO) closure procedures for those experiencing right-to-left shunt (RLS) issues.
- A total of 73 patients aged 16 to 70, including various backgrounds such as migraines and cerebral infarctions, were monitored pre- and post-operation using TEE and other echocardiographic methods.
- Results indicate that TEE significantly aids in understanding PFO anatomy and shunt characteristics, improving diagnosis rates and the overall success of the closure procedure.
Background: Hypertension is the most common chronic disease and the leading risk factor for disability and premature deaths worldwide. Approximately 10-20% of all patients with hypertension and 15-18% of the general population who are treated for hypertension have resistant hypertension (RH). Patients with RH have a higher risk of end-organ damage, such as carotid intima-media thickening, retinopathy, left ventricular hypertrophy and heart failure, myocardial infarction, stroke, impaired renal function, and death than those with controlled blood pressure.
