This study investigates the development and characterization of a novel composite material consisting polyvinyl alcohol (PVA) integrated with Uncaria gambir (UG) zinc oxide (ZnO) as fillers. The synergistic effects UG ZnO were investigated, focusing on their ability to enhance film's properties. UV-vis spectrophotometry demonstrated that film effectively blocked all UV (UV-A UV-B) blue light wavelengths. mechanical properties significantly enhanced, tensile strength improving by 56%...
We report on the fabrication and characterizations of a multiaxial stretchable interconnect using room-temperature liquid-alloy-filled elastomeric microchannels. Polydimethylsiloxane (PDMS) microchannels coated at bottom with gold wetting layer were used as reservoirs which subsequently filled by liquid alloy microfluidic injection technique. Using diamond-shaped geometry to provide biaxial performance, maximum stretchability 100% was achieved (ΔR=0.24Ω). Less than 0.02Ω resistance variation...
Abstract The objective of this study was the production rice husk flour (RHF) and wood (WF) filled polybutylene succinate (PBS) biocomposites as alternatives to cellulosic material conventional plastic (polyolefins) composites. PBS is one biodegradable polymers, made from condensation reaction 1,4‐butanediol succinic acid that can be naturally degraded in natural environment. We compared mechanical properties between plastics agro‐flour–filled biocomposites. evaluated biodegradability...
We sought to determine the surgical treatment and functional outcome identify predictors of survival in a retrospective cohort patients with spinal cord ependymoma using data collected from Korea Spinal Oncology Research Group database. The regarding 88 who had been surgically treated for histologically confirmed intramedullary extramedullary January 1989 December 2009 were retrospectively reviewed. Histopathological examination revealed myxopapillary 24 patients, 61 anaplastic 3 patients....
As a result of industrialization and environmental pollution, increasing importance is being given to eco-friendly materials technology. In particular, biocomposites using polylactic acid (PLA) have attracted great interest. this work, fiber-reinforced composites were investigated in order enhance the mechanical properties improve economic efficiency PLA. Specifically, composite natural fibers, such as kenaf actively studied. utilization kenaf, treatment method for bonding force between...
This paper reports on the properties of microscale water hyacinth fiber pulp (WHF) filled tapioca starch biopolymer (TSB) composites. The volume fraction WHF in TSB matrix is varied, that is, 1%, 3%, 5%, and 10%. A casting method used for making sample films biocomposites. Scanning electron microscopy (SEM) fracture surface biocomposite tensile samples displays good distribution matrix, interface bonding between TSB. 10% deliveres highest value strength (TS) 6.68 MPa, modulus (TM) 210.95...
With growing sustainability concerns, the need for products that facilitate easy disassembly and reuse has increased. Adhesives, initially designed bonding, now face demands selective removal, enabling rapid assembly-disassembly efficient maintenance across industries. This is particularly evident in display industry, with rise of foldable devices necessitating specialized adhesives. A novel optically clear adhesive (OCA) presented display, featuring a unique UV-stimulated removal feature....
