Dry Aerosol Direct Writing for Selective Nanoparticle Deposition

Microprocessors, long-lasting batteries, and sensors are a number of examples of nanotechnology revolutionising our daily lives. Nanotechnology is the study, development, and manufacturing of structures and devices which derive unique and novel properties from nanoscale phenomena. To realise such structures and devices, a set of processes...

Influence of thermal effect on sugars composition of Mexican Agave syrup

Agave syrup is a fermentable by-product from the Agave industry that is used for pulque production, a typical Mexican fermented beverage. However, to date, the information available on its physicochemical composition is scarce, with this study being one of the first contributions on the subject. Here the influence of thermal treatment at 121ºC...

Simultaneous improvements of the strength and ductility of fine-grained AA6063 alloy with increasing number of ECAP passes

In this research, grain refinement through severe plastic deformation (SPD) in combination with a thermal treatment to create a fine initial grain structure with a high degree of supersaturation was taken as a viable approach to achieving simultaneous increases in the hardness, strength and ductility of the aluminum alloy AA6063 during...

Aerosol Direct Writing and Thermal Tuning of Copper Nanoparticle Patterns as Surface-Enhanced Raman Scattering Sensors

Surface-enhanced Raman scattering (SERS) substrates are of great interest for detecting low-concentrated analytes. However, issues such as multistep processing, cost, and possible presence of hazardous substances in the fabrication still represent a significant drawback. In this paper, an innovative direct writing method is introduced for...
