Hemoglobin-stabilized gold nanoclusters displaying oxygen transport ability, self-antioxidation, auto-fluorescence properties and long-term storage potential

The development of hemoglobin (Hb)-based oxygen carriers (HBOCs) holds a lot of potential to overcome important drawbacks of donor blood such as a short shelf life or the potential risk of infection. However, a crucial limitation of current HBOCs is the au ...

Design of experiments to investigate multi-additive cellulose nanocrystal films

Tiffany Abitbol

Cellulose nanocrystal (CNC) suspensions can self-assemble into chiral nematic films upon the slow evaporation of water. These films are brittle, as indicated by their fracturing instead of plastically deforming once they are fully elastically deformed. Thi ...

Fabrication of micrometer-sized drops as templates for particles

Mathias Steinacher

Drops are omnipresent in our daily life for example in the form of rain drops or as oil drops in a salad dressing. On a technological basis, drops can be used to conduct chemical or biological reactions. These drops often serve as templates to produce mate ...

Evolution of microstructural changes in cement paste during environmental drying

Karen Scrivener, Fabien Jacques Michel Georget, Hamed Maraghechi, Wioletta Soja

Exposure of concrete to the atmosphere changes the microstructure of the cement paste. However, knowledge about the alteration of the porosity due to drying is typically not considered in deterioration processes of the hardened cement paste. The purpose of ...

Production of Additive‐Free Amorphous Nanoparticles with a SAW‐Based Microfluidic Spray‐Dryer

Esther Amstad, Huachuan Du, Mathias Steinacher, Duncan Christophe Emmanuel Gilbert

Spray‐drying is a widely employed, cost‐effective process to formulate solutions into solid particles of controlled sizes and compositions. In addition, this process can also offer control over the structure of spray‐dried particles: if the solvent is evap ...

Cell-free soil bio-cementation with strength, dilatancy and fabric characterization

Lyesse Laloui, Dimitrios Terzis

A multi-disciplinary approach is adopted in the present work towards investigating bio-cemented geo-materials which extends from sample preparation, to microstructural inspection and mechanical behaviour characterization. We suggest a new way to induce “ce ...
