Enhanced Strain Transfer and Optoelectronic Performance in MoS2 Devices via Formvar Encapsulation
We systematically investigate the influence of polyvinyl formal (PVFM), commonly known as Formvar, in comparison to polycarbonate (PC) and polymethyl methacrylate (PMMA), as encapsulation materials on the strain performance of MoS2 monolayer and bilayer flakes on flexible polypropylene (PP) substrates. Notably, optical differential reflectance measurements reveal that PVFM and PMMA encapsulation significantly enhances the mechanical and thermal strain gauge factors by approximately 2-fold (up t…

Nanoconfinement Effects on Intermolecular Forces Observed via Dewetting
Although wettability is a macroscopic manifestation of molecular-level forces, such as van der Waals (vdW) forces, the impact of nanoconfinement on material properties in reduced film thickness remains unexplored in predicting film stability. In this work, we investigate how nanoconfinement influences intermolecular interactions using a model trilayer system composed of a thick polystyrene (PS) base, a poly(methyl methacrylate) (PMMA) middle layer with tunable thickness (15-95 nm), and a 10 nm …

Radionuclide Production for Dose Verification in VHEE FLASH Radiotherapy
This study explores the production of radionuclides in a PMMA (Polymethylmethacrylate) phantom irradiated with Very High Energy Electrons (VHEE) beams as a novel method for dose verification. In this work, Monte Carlo simulation studies using the Geant4 toolkit and experimental measurements with a VHEE beam produced by a laser-plasma accelerator were conducted. Specifically, the photonuclear production of 11C, 15O and 13N is examined, with a detailed analysis of their spatial distribution, prod…
