Three new xanthone compounds, 1,3,5-trihydroxy-2-(2-hydroxy-3-methylbut-3-enyl)-4-(3-methylbut-2-enyl)xanthone (1), toxyloxanthone E (2), dehydrocycloguanandin B (3) along with 15 known xanthones (4-18) were isolated from the aerial parts of Calophyllum polyanthum Wall. ex Choisy. Their structures...

Steam explosion (SE) pretreatment is a widely adopted method for enhancing enzymatic hydrolysis of lignocellulosic biomass in biorefinery. In this work, moderate SE pretreatment was employed to overcome the recalcitrance of cell wall through systematically assessing physicochemical and structural...

In this study, torrefaction under mechanical pressure of 10-70 MPa at 250°C was proposed as a pretreatment method and its effect on pyrolysis behaviours of Leucaena (LC) was examined at 900°C. It was found that the mechanical pressure applied during torrefaction could significantly increase the...

The conversion of biomass to produce high-valued fuel is an important way to improve the utilization rate of biomass energy. For the coupled utilization of solar energy and biomass, molten salts are used as heat storage and catalytic medium to convert biomass into combustible gases. To balance the...

Moso bamboo is one of the fast-growing renewable materials and comparable in strength to other commonly used construction materials. The main impediment to a widespread use of bamboo in structural applications is the inherent variability in its geometric and mechanical properties. Despite the...

In this study, wood flour/polypropylene (WF/PP) composites were prepared by incorporating 2 wt% carbon materials with different morphologies, including carbon black (CB), graphite (G), and multi-walled carbon nanotubes (CNTs). WF/PP composite without any additives was included as a reference. All...

High solid loading enzymatic hydrolysis (HSLEH) produces high sugar concentrations with low water and energy inputs. Adequate information has been provided to confirm the excellent enzymatic digestibility of pretreated bamboo biomass with the solid content below 10%. However, the utilization of...

The preparation of xylooligosaccharides (XOS) from lignocelluloses by organic acid hydrolysis has the advantages of high efficiency and simplicity, but reducing the production of by-products, especially xylose, is a prerequisite for commercial preparation of XOS using organic acid. In this work, to ...

The 2.5 mm bamboo charcoal ultra-thick electrode material was prepared by direct carbonization of bamboo which preserved its straight pore structure. The bamboo charcoal materials Z-700, Z-800, and Z-900 were prepared at 700, 800 and 900°C, which were characterized by SEM, XPS, Raman spectra...

Advocating low-carbon has become the consensus of all countries in the world and a necessary means of sustainable development . Humidity-control materials (HCMs) can smartly regulate indoor air humidity without energy consumption, thereby greatly reducing building energy consumption. However, the...
