Enhancing Hydrogen Evolution Reaction through Coalescence-Induced Bubble Departure on Patterned Gold-Silicon Microstrip Surfaces.
ACS Appl Mater Interfaces

Hydrogen bubble adhesion to the electrode presents a major obstacle for green hydrogen generation via the hydrogen evolution reaction (HER) as it would induce undesired overpotential and undermine the reaction efficiency by reducing reaction area, increasing transport resistance, and creating an undesired ion concentration gradient. While electrodes with aerophobic/hydrophilic surfaces have been developed to facilitate bubble detachment, they primarily rely on micro- and nanostructured catalyst surfaces to enhance buoyance-induced bubble departure. Here, we demonstrate that introducing nonreactive yet more hydrophilic surfaces can promote coalescence-induced bubble departure, thereby significantly reducing the transport overpotential and improving HER performance.

Ferroptosis combined with photodynamic therapy (PDT) has emerged as a powerful approach to induce cancer cell death by producing and accumulating lethal reactive oxygen species (ROS) in the tumor microenvironment (TME). Despite its efficacy and safety, challenges persist in delivering multiple drugs to the tumor site for enhanced antitumor efficacy and improved tissue targeting. Hence, we designed a method of inducing ferroptosis through laser-mediated and human homologation-specific efficient activation, which is also a ferroptosis therapy with higher safety through ROS-mediated.

Bacterial bots are potent vehicles in cancer theranostics where bacteria are used typically as cargos for drug delivery. However, living bacteria themselves may aid in their efficiency in killing the tissues. For example, living bacteria may be functionalized with magnetic and luminescent nanoparticles along with drugs in order to achieve the targeted delivery and release of payloads that would include the bacteria.

Department of Radiation Oncology, Christiana Care, Helen F. Graham Cancer Center & Research Institute, Newark, Delaware.
Superficial lesions of the face are often treated with an electron beam and surface collimation utilizing a conformal lead shield with an opening around the region of treatment (ROT). To fabricate the lead shield, an imprint of the patient face is needed. Historically, this was achieved using a laborious and time-consuming process that involved a gypsum imprinted model (GIM) of the patient topography.

Background: Despite increasing awareness in general practice, heart failure with preserved ejection fraction (HFpEF) remains under-diagnosed in the community due to diagnostic difficulties. Dedicated dyspnea clinics are responsible for diagnosing HFpEF and efficient referral from primary care physicians is the key to enhance its role.
Methods: This retrospective analysis was performed to assess the effectiveness of a one-year collaborative project between our dyspnea clinic and the Maebashi Medical Association.
