polyurethane hydrogels with strong mechanical strength and high water-absorption ratio may find their applications in soil-water conservation and desertification combating. By carefully tuning the structure of polyols and the density of the cross-linkable functional groups, professor WAN Xiaobo and his colleagues found a way to unify the high water-absorption ratio and high compressive strength in one material.
Polyurethanes that could form hydrogel when contacted with water are of great interests for their plausible applications. It could be used as high-performance industrial materials and materials for medical treatment.

Lignocelluloses are abundant resources on earth. They can be converted to energy, materials, or chemicals to replace the depleting fossil sources. However, it is difficult to achieve efficient conversion due to their natural recalcitrance. The QIBEBT scientists carried out a series of researches on pretreatment and efficient utilization of inexpensive and renewable lignocelluloses. Lignocelluloses are abundant resources on earth. They can be converted to energy, materials, or chemicals to replace the depleting fossil sources. However, it is difficult to achieve efficient conversion due to their natural recalcitrance.

Microalgae are promising feedstock for fuels and chemicals. However little was known about the transcriptional regulation networks in oleaginous microalgae. Researchers from Single-Cell Center of QIBEBT unveiled the first genome-wide transcriptional regulation network for oleaginous microalgae and paved the way for genetic engineering for enhanced oil productivity in microalgae. Microalgae are promising feedstock for fuels and chemicals because many species possess the ability to grow rapidly and synthesize large amounts of storage neutral lipids from sunlight and carbon dioxide. They can be cultivated on non-arable land ...
