Study of the terahertz spectra of crystalline materials using NDDO semi-empirical methods: polyethylene, poly(vinylidene fluoride) form II and $α$-D-glucose [PDF]
arXiv, 2016 Semi-empirical quantum chemistry methods offer a very interesting compromise between accuracy and computational load. In order to assess the performance of NDDO methods in the interpretation of terahertz spectra, the low frequency vibration modes of three crystalline materials, namely, polyethylene, poly(vinylidene fluoride) form II and $\alpha$-D ...

A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)
Advanced Functional Materials, EarlyView.To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Scintillation Timing Characteristics of Common Plastics for Radiation Detection Excited With 120 GeV Protons [PDF]
arXiv, 2019 The timing characteristics of scintillators must be understood in order to determine which applications they are appropriate for. Polyethylene naphthalate (PEN) and polyethylene teraphthalate (PET) are common plastics with uncommon scintillation properties.

A Flexible Photovoltaic Fatigue Factor for Quantification of Mechanical Device Performance
Advanced Functional Materials, EarlyView.The flexible Photovoltaic fatigue factor (F) quantifies mechanical and photovoltaic performance as a function of the power conversion efficiency (PCE), the strain (ε${\varepsilon}$), and the number of bending cycles (NBC) in bending tests. The strain depends on the bending radius (R) and the thicknesses of the substrate (ts) and the photovoltaic device

Biofilm Control by Active Topography with Mucin Coating
Advanced Functional Materials, EarlyView.This study reports a new antifouling strategy based on a bioinspired design. Mucin coating enhances biofilm control by active topography with beating micron‐sized pillars. Besides the mechanical force of beating pillars, the antibiofilm activities also involve biological factors since mucin coating inhibits swarming motility and c‐di‐GMP synthesis in ...
