The effect of airflow rate, biomass moisture content, particle size, and compactness on the surface properties of biochar produced in a top-lit updraft gasifier was investigated. Pine woodchips were studied as the feedstock. ...

In this study, the impact of isolation conditions on structural and surface properties at the air/water interface of soy-whey proteins (SWP) was assessed. SWP were obtained by precipitation of soy-whey (at pH 4.5 or 8.0) ...

This work discusses the land surface-atmosphere interactions during the severe drought that took place in 2008 in southern South America. The drought was among the most severe in the last fifty years both in terms of ...

Yeast cell wall proteins were extracted from homogenized suspensions with 0.75 mol/l NaOH, yielding after precipitation at isoelectric pH a pale-brown sediment. Lyophilized sample was fractionated on Sephadex G-50 to yield ...

Solid-state gas sensors transduce a chemical quantity, such as a gas concentration, into an electric signal. Metal-oxide semiconductors are the most common inorganicmaterials used in chemical sensing of gases and vapors. ...

Tunable hardness materials have shown fascinating properties, which place them as potential materials for use in different technological fields. This work deals with the bulk and confined synthesis of copolymers based on ...

We show that an azopolymer can be used to create a supramolecular architecture in a parallel process with patterned surface properties. By illuminating with an interference pattern, we created adhesion and charge patterns ...

Protoplasts isolated from arugula leaves show the appearance of hydrophobic regions in the surface when cell volume is increased as detected using by Merocyanine 540 (MC540). The analysis of the equilibrium of the dye ...
