Differential expression of the vegetative and spore-bound hydrophobins of Trichoderma reesei - Cloning and characterization of the hfb2 gene

, 1997
The hfb2 gene encoding the hydrophobin HFBII of the filamentous fungus Trichoderma reesei was isolated by heterologous hybridization using the vegetative hydrophobin I, hfb1, gene of T. reesei as a probe. The hfb2 gene codes for a typical fungal secreted

Process Integration Approach for the Efficient Synthesis of Metal Boride Ceramics

Chemical Engineering Transactions
Inspired by the principle of process integration, a novel Self-propagating High-temperature Synthesis (SHS) route based on the combination of direct (DR) and borothermal (BR) reactions is proposed in this work for the synthesis of transition metal ...

Insight into phase stability and mechanical behavior of HfB2 and HfB12 under high pressures and high temperatures: A first-principles investigation

Previous attempts to synthesize pure crystalline hafnium dodecaboride (HfB12) have been unsuccessful, raising doubts about its existence as one of the thermodynamically stable phases in the binary Hf-B system.
