Recently, the research team led by Dr. LI Bin from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), extracted lignin-containing cellulose nanofibrils (CNFs) via a one-step recoverable organic acid hydrolysis plus homogenization in dimethylacetamide (DMAC). The resultant CNFs were directly used to fabricate strong, flexible, and water resistant CNP without any complex chemical modification. Cellulose nanopaper (CNP) has potential application in the fields of electronic devices, visual display substrates, batteries, barrier material due to its renewability, light-weight, low thermal expansion, excellent mechanical properties and optic...

Recently, a research team led by Prof. LI Fuli from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), proposed a wirewalking mode for processive degradation of crystalline cellulose by an endoglucanase, which provided insights for rational design of industrial cellulases. Cellulose is the earth’s most abundant biopolymer which is responsible for the structural integrity of plants. Processive cellulases are essential in crystalline cellulose degradation as they continuously catalyze and slide along the cellulose ch...

05 2018A research team led by Prof. ZHAO Guang from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS) achieved the high-value chemicals of glycolate and ethylene glycol from xylose in Escherichia coli. Lignocellulosic biomass, refers to plant dry matter, is the most abundant and low-cost renewable resource on the planet. Xylose is the second most abundant sugar in nature which accounts for 18–30% of sugar in lignocellulose. Hence, efficiently m...

The Protein Design Group, led by Professor YAO Lishan from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy Sciences, developed a new Nuclear Magnetic Resonance (NMR) method to detect the J-coupling across the CH/CH van der Waals interaction between protein aliphatic side chain groups. For the first time, a quantitative analysis of van der Waals' interaction in proteins has been achieved. This study was published on Journal of the American Chemical Society. Proteins are essential parts of organisms and participate in virtually every process within cells. There are many non-covalent interactions in protein which are critical to protein structure and function. Van der Waals force is a kind of non-coval...

A research, leaded by Prof. PADTURE Nitin P. (Brown University, USA), Prof. ZHOU Yuanyuan (Brown University, USA) and Prof. PANG Shuping (Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, China) demonstrated the continuous chemical functionalization of grain boundaries in perovskite thin films by using a tri-block copolymer that exhibits both hydrophilicity and hydrophobicity. The related work was published in Chem. For the past few years, the rise of the photovoltaic industry is inseparable from various new types of solar cells. Organic-inorganic halide perovskites are a family of crystalline semiconducting materials that are revolutionizing the field of pho...

Carbon Based Energy Conversion Materials Research Team led by Professor JIU Tonggang, Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), conducted a novel approach of dual doping GD into electron transport layers of PSCs, where the conductivity of electron transport layers was boosted, the resulting device performance was improved, and the certified power conversion efficiency (PCE) of 20% was obtained. The related work was published in Nano Energy. Graphdiyne (GD), an advanced full carbon nano structured material, has drawn extensive attention following in the footsteps of studies on Fullerene, carbon nanotubes and Graphene. It is regarded as the most stable synthetic allotrope of carbon fam...
