Development of miniaturized thin-film lithium-ion batteries (TF-LIBs) using vacuum deposition techniques is crucial for low-scale applications, but addressing low energy density remains a challenge. In this work, structures analogous to SiO-based thin-film electrodes are designed with close resemblance to traditional LIB slurry formulations including active material, conductive agent, and binder. The thin-film is produced using mid-frequency sputtering with a single hybrid target consisting of SiO nanoparticles, carbon nanotubes, and polytetrafluoroethylene.

Background: The irrational use of antibiotics is a global issue and it can lead to morbidity, mortality, and increased health care costs. Hence, proper use of antibiotics is imperative and should be included in the pharmaceutical care plan.
Objective: The objective of this study was to evaluate the prescribing pattern of antibiotics for children using WHO core prescribing indicators.
