Novel approach to extract thermally stable cellulose nanospheres with high yield
A facile approach for extracting cellulose nanospheres (SCNCs) was presented through hydrochloric acid hydrolysis of lyocell fibers under hydrothermal condition. The SCNCs showed spherical nanoparticles with an average diameter of 25 nm. Compared to the lyocell fibers, high yield of up to 85.3%, crystallinity of 85.2% and the maximum degradation temperature (Tmax) of 347.2 1C for ...

30. Synthesis and Properties of Cross-Linkable High Molecular Weight Fluorinated Copolyimides
A series of novel high molecular weight fluorinated co-polyimides (Co-PIs) containing styryl side chain based on 1,3-bis(2-trifluoromethyl-4-aminophenoxy)-5-(2,3,4,5-tetrafluorophenoxy)benzene (6FTFPB) were successfully synthesized. The weight-average molecular weights (M(w)s) and polydispersities of the co-polyimides were in the range 8.93-10.81 x 10(4) and 1.33-1.82, respectively. The co-polyimi...

21. Preparation and properties of high-performance polyethersulfone composites reinforced by modified silicon nitride
Si3N4 fillers were added to polyethersulfone (PES) using the solution mixing and ball-mill mixing methods to increase the thermal conductivity. 3-Aminpropyltriethoxysilane was used as a coupling agent for the surface modification of the Si3N4 particles. The morphology, thermal stability, mechanical properties, and thermal conductivity of the Si3N4/PES composites were then studied in detail. The di...

Controlled droplet transport to target on a high adhesion surface with multi-gradients
We introduce multi-gradients including Laplace pressure gradient, wettable gradient and wettable different gradient on a high adhesion surface via special wedge-pattern and improved anodic oxidation method. As a result of the cooperative effect mentioned above, controlled directional motion of a droplet on a high adhesion surface is realized, even when the surface is turned upside down. The drop...

Improving the flame-retardant efficiency of aluminum hydroxide with fullerene for high-density polyethylene
The influence of fullerene (C-60) on the flame retardancy and thermal
stability of high-density polyethylene (HDPE)/aluminum hydroxide (ATH)
composites was studied. After the addition of three portions of C-60 to
an HDPE-ATH (mass ratio=100:120) composite, a V-0 rating in the UL-94
vertical combustion test was achieved, and the limiting oxygen index
increased by about 2%. The resu...

High Capacity Hydrogen and Nitric Oxide Adsorption and Storage in a Metal-Organic Framework
Gas adsorption experiments have been carried out on a copper benzene tricarboxylate metal?organic framework material, HKUST-1. Hydrogen adsorption at 1 and 10 bar (both 77 K) gives an adsorption capacity of 11.16 mmol H2 per g of HKUST-1 (22.7 mg g-1, 2.27 wt %) at 1 bar and 18 mmol per g (36.28 mg g-1, 3.6 wt %) at 10 bar. Adsorption of D2 at 1 bar (77 K) is between 1.09 (at 1 bar) and 1.20(at &l...

Supramolecular Aggregate as a High-Efficiency Gene Carrier Mediated with Optimized Assembly Structure
For cancer gene therapy, a safe and highefficient gene carrier is a must. To resolve the contradiction between gene transfection efficiency and cytotoxicity, many polymers with complex topological structures have been synthesized, although their synthesis processes and structure control are difficult as well as the high molecular weight also bring high cytotoxicity....

(CP) Dithiocarbamate-modified starch derivatives with high heavy metal adsorption performance
In this work, three types of dithiocarbamate (DTC)-modified starch derivatives including DTC starch (DTCS), DTC enzymolysis starch (DTCES) and DTC mesoporous starch (DTCMS) were developed, which showed the significant heavy metal adsorption performance. The adsorption ability of these three DTC modified starch derivatives followed the sequences: DTCMS > DTCES > DTCS. I...
