Competing Effects of Hydration and Cation Complexation in Single-Chain Alginate

Alginic acid, a naturally occurring anionic polyelectrolyte, forms strong physically cross-linked hydrogels in the presence of metal cations. The latter engage in electrostatic interactions that compete with intra- and intermolecular hydrogen bonds, determ ...

Islet Encapsulation: New Developments for the Treatment of Type 1 Diabetes

Sandrine Gerber, Qixing Zhang, Yi Wang, Léo Bühler

Islet transplantation is a promising approach for the treatment of type 1 diabetes (T1D). Currently, clinical islet transplantation is limited by allo - and autoimmunity that may cause partial or complete loss of islet function within a short period of tim ...

Fate of parasites and viruses in calcium hydroxide-treated urine in relation to temperature and moisture content

Tamar Kohn, Loïc Decrey

Human urine can be used as fertilizer and technologies, such as alkaline-urine treatment, are being developed to enable easier re-use. There is, however, a risk of pathogens being present in the urine. This hygiene assessment examined inactivation of three ...

Synthesis of heterogeneous catalysts with metal oxide overcoat for renewable catalysis applications

Yuan-Peng Du

Metal oxide deposition is an emerging synthetic technique for designing heterogeneous catalysts. Depositing a nanoscale overcoat of metal oxide on heterogeneous catalysts can modify their structural and chemical characteristics. Many deposition approaches, ...

Amorphous silicon passivated contacts for diffused junction silicon solar cells

Aïcha Hessler-Wyser, Stefaan De Wolf, Bénédicte Demaurex

Carrier recombination at the metal contacts is a major obstacle in the development of high-performance crystalline silicon homojunction solar cells. To address this issue, we insert thin intrinsic hydrogenated amorphous silicon [a-Si: H(i)] passivating fil ...

Field-Effect Transistors Based on ZnO Nanowires

Daniel Dominik Kälblein

Semiconductor nanowires are an emerging class of materials with great potential for applications in future electronic devices. The small footprint and the large charge-carrier mobilities of nanowires make them potentially useful for applications with high- ...

Multiple Nanowire Species Synthesized on a Single Chip by Selectively Addressable Horizontal Nanochannels

Anna Fontcuberta i Morral

The synthesis of horizontal porous anodic alumina (PAA) structures with individually addressable channel systems is demonstrated. This was achieved by developing a multicontact design of aluminum finger structures (two to Five contacts) on silicon wafers. ...

Effect of natural organic matter and green microalga on carboxyl-polyethylene glycol coated CdSe/ZnS quantum dots stability and transformations under freshwater conditions

The influence of pH, ionic strength, presence of humic or alginic acids, extracellular polymeric substances (EPS), or freshwater microalga Chlorella kesslerii on the stability and transformation of carboxyl-PEG-CdSe/ZnS core/shell quantum dots (QDs) in ter ...

Conformational Changes and Aggregation of Alginic Acid as Determined By Fluorescence Correlation Spectroscopy

Marianne Seijo, Fabrice Avaltroni, Serge Stoll

Insight into the conformations and aggregation of alginic acid was gained by measuring its diffusion coefficient at very dilute concentrations using fluorescence correlation spectroscopy. Both the pH and ionic strength (I) had an important influence on the ...

Ductal cells of the pancreas

Anne Grapin-Botton

Ductal cells of the pancreas form the epithelial lining of the branched tubes that deliver enzymes produced by pancreatic acinar cells into the duodenum. In addition, these cells secrete bicarbonate that neutralizes stomach acidity. During development, epi ...
