Electrospinning: enzyme encapsulation for food industry

On July 20th  2017, the U.S. National Institute of Food and Agriculture (NIFA), part of the Department of Agriculture (USDA), announced a $4.6 million grant for research on nanotechnology applied to agriculture and food industry. “Nanotechnology is being rapidly implemented in medicine, electronics, energy, and biotechnology, and it has huge potential to enhance the agricultural… Continue reading Electrospinning: enzyme encapsulation for food industry

Hydrophobic coatings I

Hydrophobicity phenomena are present in nature; in the leaves of plants such as Nelumbo nucifera (lotus), in the wings of butterflies, or in the legs of water striders. It is also a leading surface property for corrosion protection, as hydrophobic surfaces are water and aqueous electrolytes repellant, anti-icing, bio-corrosion and anti-fouling [1]. These properties can… Continue reading Hydrophobic coatings I

Sol-gel and architecture I: anti-reflective coatings

The use of light building envelopes, made of materials such as steel and glass, has progressively substituted the traditional concrete and brick structures. This change poses new design challenges in order to control parameters such as the solar factor, the thermal transmittance, visual transmittance, reflection index, among others [1]. The thermal and energetic efficiency of… Continue reading Sol-gel and architecture I: anti-reflective coatings
