1. Superhydrophobic silicon fabricated by phosphomolybdic acid-assisted electrochemical etching
Controllable geometry silicon surfaces with superhydrophobicity are difficult to be fabricated without photolithography techniques. Superhydrophobic silicon surfaces with water contact angle larger than 150º and sliding angle less than 10º have been successfully fabricated by electrochemical etching strategy. Squarelike hole arrays with controllable geomet

2. NEXAFS and FTIR-ATR investigation of the static and dynamic superhydrophobicity of functionalized titanium dioxide nanoparticle coatings
Superfícies super-hidrofóbicas com ângulos de contacto maiores ou iguais a 159º foram preparadas utilizando nanopartículas de dióxido de titânio e trimetoxipropil silano (TMPSi) em solventes aquosos ou não aquosos. A superfície super-hidrofóbica preparada em solvente aquoso mostrou uma histerese angular alta. Por outro lado, a superfície super-hid

3. Modelagem bidimensional de hidrofobicidade e superhidrofobicidade em superfícies de pilares / Two dimensional modeling of hydrophobicity and superhidrophobicity on pillar-like surfaces
In this work we investigate the use of the Potts Cellular Model in simulations of the water droplets on flat hydrophobic and pillarlike surfaces surrounded by gas. Eight tests were chosen to validate the model, based on experimental and theoretical results: (1) the measurement of the contact angle on a flat hydrophobic surface; (2) the transition from Cassie
