Searching for materials to provide proper housing with less emission and low energy becomes an urgent demand with the ever-growing population. Bamboo has gained a reputation as an ecofriendly, highly renewable source of material. Parallel Strand Bamboo (PSB) is a new biocomposite made of bamboo strips which has superiority performances than wood products. It has attracted considerable interests...
Incorporation of biofuels into the existing selection of fuels is a very important measure to slow down environmental destruction and to counter the imminent fossil fuel shortage. Biogas is a very interesting option for use in both electricity and heat production, and also as a fuel for vehicles. The positive fuel characteristics of biogas and the high yields of biogas obtained from traditional...
Composites based on waste products from the production of 5-hydroxymethylfurfural - "humins" and melamine or urea (as a cross-linking agent) with wood fl our filler, 70 % by weight) were obtained. Studies physical mechanical properties materials different contents have been carried out, which shown that composites humins: (2,5: 1) humins:urea (2:1) tensile strength 150 165 MPa, respectively, si...
A number of years ago the Green Chemistry Centre of Excellence at York discovered new high surface area forms of polysaccharides. Further study of these materials has found that after controlled thermal treatment they exhibit remarkable thermal properties, which have enabled us to make an entirely new class of materials with properties ranging from starch-like to carbon-like (see figure 1). Tra...
Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions and properties. Complex metal hydrides are a rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex metal hydrides may store hydrogen in the solid state, ac...
Hydrogen is recognized as a potential and extremely interesting energy carrier, which can facilitate efficient utilization of unevenly distributed renewable energy. Furthermore, hydrogen has an extremely interesting chemistry and form compounds with most elements in the periodic table and with a variety of different types of bonds. Metal hydrides has recently become very interesting as new clas...
