Evaluation of the Catalytic Effect of Metal Additives on the Performance of a Combined Battery and Electrolyzer System.
ACS Appl Energy Mater
January 2025
Hollingsworth and Vose, Groton, Massachusetts 01450, United States.
A low-cost method of green hydrogen production via the modification of a lead acid battery has been achieved, resulting in a hydrogen flow rate of 5.3 L min from a 20-cell string. The electrochemical behavior and catalytic effect of various metal additives on the hydrogen evolution reaction (HER) was evaluated using cyclic voltammetry.

Surface-enhanced Raman scattering (SERS) substrates are garnering increasing interest for ultrasensitive high-throughput sensing. Notably, SERS-encoded nanostructures stand out due to their potential for nearly unlimited codification with excellent optical properties. In this paper we report a simple, versatile and cost-effective method for preparing SERS-encoded clusters.

Selective modification of chemically active sites on supports, such as steps, edges, and corners, with metal nanoparticles (NPs) is a challenging topic in the fields of catalysis and photocatalysis. However, the formation of site-selective, high-density metal NPs on a support has not yet been achieved. Radial ZnO mesocrystals composed of hexagonal nanowires (NWs) with {101̅0} sidewalls were synthesized by a simple solution-phase method.

Background: Despite patent ductus arteriosus closure in premature infants is a relatively fast procedure, it involves specific steps for equipment exchange and the use of a 4-Fr catheter, which may be large for tiny infants, potentially causing haemodynamic instability or tricuspid valve regurgitation.
Objectives: This study aims to describe the early experience with a new technique designed to simplify transcatheter patent ductus arteriosus closure in premature infants. It enables the closure using the KA micro plug device via a single microcatheter without equipment exchanges and contrast exposure.
Low-Cost Modification to Enhance Bone Marrow Aspiration Efficiency: A Technical Report.
Cureus
December 2024
Anesthesiology, All India Institute of Medical Sciences, Bhopal, Bhopal, IND.
Bone marrow aspiration is an essential procedure for diagnosing hematological conditions and therapeutic applications, such as bone marrow aspirate concentrate (BMAC) therapy for non-union of bones. This report presents a case of a 35-year-old male with femoral non-union treated with BMAC, requiring the collection of a large bone marrow aspirate volume. A novel, low-cost modification to the standard bone marrow aspiration apparatus was developed using components from an intravenous (IV) drip set, including a rubber bulb connector and a luer lock connector.
