Effect of Backsheet Properties on PV Encapsulant Degradation during Combined Accelerated Aging Tests

Andreas Schueler, Djamel Eddine Mansour

Long-term photovoltaic (PV) module reliability is highly determined by the durability of the polymeric components (backsheet and encapsulation materials). This paper presents the result of experiments on encapsulant degradation influenced by the backsheet ...

Transformation of Glucose to 5-Hydroxymethylfurfural Over Regenerated Cellulose Supported Nb2O5 center dot nH(2)O in Aqueous Solution

Paul Joseph Dyson, Zhaofu Fei, Lu Chen, Fangmin Huang

Niobic acid (Nb2O5 center dot nH(2)O) was immobilized on regenerated cellulose (Re-Cellulose) to afford a heterogeneous catalyst, termed Nb2O5 center dot nH(2)O@Re-Cellulose, that was characterized by powder X-ray diffraction, microscopy (SEM and TEM) and ...

Parietal Structures of Escherichia coli Can Impact the D-Cateslytin Antibacterial Activity

Georg Fantner, Oliver Peric

Bacterial resistance to conventional antibiotics is of major concern. Antimicrobial peptides (AMPs) are considered excellent alternatives. Among them, D-cateslytin (D-Ctl, derivative of a host defense peptide) has shown high efficiency against a broad spec ...

Leather-Promoted Transformation of Glucose into 5-Hydroxymethylfurfural and Levoglucosenone

Paul Joseph Dyson, Felix Daniel Bobbink, Florent Menoud, Zhangjun Huang

The search for efficient catalysts frequently leads to new homogeneous and heterogeneous catalysts of increasing complexity, and sometimes common, natural, or hybrid natural/synthetic materials that could be used in catalysis are overlooked. For example, t ...

Combining ultra-high resolution ion-mobility spectrometry with cryogenic IR spectroscopy for the study of biomolecular ions

Thomas Rizzo, Robert Paul Pellegrinelli, Ahmed Ben Faleh, Stephan Warnke, Natalia Yalovenko

Double-resonance spectroscopic schemes in combination with cryogenic ion traps are the go-to techniques when isomer-specific high-resolution spectra are required for analysis of molecular ions. Their limitation lies in the requirement for well-resolved, is ...

Effect of light and oxygen on repetitive bacterial inactivation on uniform, adhesive, robust and stable Cu-polyester surfaces

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

This study reports new findings on the sputtered Cu-polyester (Cu-PES) bacterial inactivation under low intensity visible light (lambda > 400 nm). Cu-PES samples sputtered for 160 s led to the complete inactivation of E. coli in anaerobic and aerobic media ...
