Full instantaneous de-icing using extensional modes: The role of architectured and multilayered materials in modes decoupling.

Ultrasonic de-icing systems are energy-efficient solutions for ice protection. The systems generate high levels of stress in the ice by inducing vibrations in the substrate, resulting in bulk or adhesive ice failure and, ultimately, ice removal. For this purpose, two types of resonant modes can be excited: flexural and extensional modes.

Transfer of Biomatrix/Wood Cell Interactions to Hemicellulose-Based Materials to Control Water Interaction.

The family of hemicelluloses stands out as a very promising natural resource that can be utilized as a biobased materials feedstock. An in-depth understanding of the hemicellulose inherent structural and property features as well as the structure-property relationships induced by the specific supramolecular hierarchical organization of lignocellulosic biopolymers will be a key enabling technology in the emerging biorefinery sector. This Review aims to give a perspective on these issues and demonstrate how the transfer of molecular wood cell interactions into hemicellulose-based materials may offer new design principles for material formulations.

A novel neutral, halophile Stachybotrys microspora-based endoglucanase active impact on β-glucan.

The production of cellulases from Stachybotrys microspora strain (A19) has been improved by fed-batch fermentation on Avicel cellulose 10 mg/ml. An endoglucanase EG2 was purified to homogeneity. This cellulase has a molecular mass estimated to 50 kDa when analyzed by a denaturant gel electrophoresis.
