Design of a POSS-modified Zeolite Structure and the Study of the Enhancement of Ammonia-nitrogen Removal from Drinking Water

Lin D., Wang D., Zhang Q., You H., Shetty K., Hu L., Harbin Institute of Technology, CN

This research explored the utilization of a waste resource, rice hull ash (RHA), for the synthesis of the polyhedral ologomeric silsesquioxane (POSS) modifier for mesoporous zeolite molecular sieve (ZMS) to enhance NH4+ ion-exchange capacity in [...]

Impacts of Three nC60 Dispersal Methods on E. coli Growth

Dai J., Chen G.H., HKUST, CN

The preparations of nC60 through water directly and toluene or THF indirectly represent all possible dispersal routes of fullerene particles in aquatic ennvironemnts. These different dispersal routes may result in different toxicity on microorganisms such [...]

Preparation and Characterization of Coenzyme Q10-Loaded Nanostructured Lipid Carriers as Delivery Systems for Cosmetic Component

Wang H., Xia Q., Southeast University, Nanjing, China, CN

Nanostructured Lipid Carrier (NLC) was a kind of nanosized carrier for lipophilic active compounds. Coenzyme Q10 (CoQ10) which is a versatile anti-oxidant is practically insoluble and chemically labile in water and should be incorporated in [...]

Nanomaterials Employed in Effective Tumor Treatment

Liang X-J., National Center for Nanoscience and Technology of China, CN

Chemotherapy is one of most effective cures to treat different of malignant tumors. Cisplatin is a chemotherapeutic compound commonly used in clinics, however, acquired resistance confines its application in chemotherapeutics. To overcome the acquired resistance [...]

Synthesis and characterization of methoxy poly(ethylene glycol)-O-chitosan-polyethylenimine as a noviral carrier for gene delivery and expression

Yu Y.Y., Wang G., Wang Z., Cai L., Wang G., Wang Z., Yang X., Xu X.H., Xu Z.G., Wan X.P., Wang G., Wang Z., Xu X.H., Xu Z.G., Li Y., Jiang Q., Gao R., Sichuan University, CN

A novel water-soluble chitosan (CS) derivative，methoxy poly(ethylene glycol)-O-chitosan- polyethylenimine(mPEG-O-CS-PEI), was synthesized by grafting polycationic polyethylenimine (PEI) and methoxy poly (ethylene glycol) (mPEG) onto chitosan, the copolymer was characterized and confirmed by 1H-NMR and FT-IR spectra. [...]

Synthesis and characterization of FITC-aminated agarose as highly-fluorescent labeling agent

Zhang L., Huang J., Chu B., Tang S., Jinan University, CN

A new fluorescent agent, FITC labeling agarose is designed to determine whether it can act as an effective fluorescent labeling agent of cell or not. The degraded agarose reacted with 3-chloro-1, 2-epoxypropane in NaOH medium [...]

Compact Modeling of Signal Transients for Dispersionless Interconnects With Resistive, Capacitive and Inductive Terminal Loads

Liu Chi, Zhou Z., Lin X., Xia J., Zhang X., He J., Peking University, CN

In this paper, compact models for transient response of dispersionless interconnects are rigorously derived with resistive, inductive and capacitive terminal loads. The proposed compact models are verified by the HSPICE simulation with high accuracy and [...]

Analytic Channel Potential Solution of Symmetric DG AMOSFETs

Chen L., Xu Y., Zhang L., Zhou W., Zhou X., Zhou W., Zhou X., He J., Peking University, CN

This paper presents an analytic channel potential solution of the symmetrical DG AMOSFETs. The proposed solution is derived from complete 1-D Poisson-Boltzmann equation by taking three components of net charge density (fixed charge, holes and [...]

A Unified Charge-Based Model for SOI MOSFETs Valid from Intrinsic to Heavily Doped Channel

Zhang J., Zhang L., He J., Zhang J., Zhang L., Zhou X., Zhou Z., Zhou X., Zhou Z., Peking University, CN

A unified charge-based model for SOI MOSFETs is presented. The proposed model is valid and accurate from intrinsic to heavily doped channel with various structure parameter variations. The framework starts from one-dimension Poisson-Boltzmann’s equation. Based [...]

Non-Charge-Sheet Analytic Model for Ideal Retrograde Doping MOSFETs

Zhou X., Zhou Z., Zhang J., Zhou X., Zhou Z., Lin X., He J., Peking University, CN

This paper presents a physics-based non-charge-sheet analytic model for an ideal retrograde doping MOSFET structure. The model adopts an approach of solving Poisson’s equation for the heavily-doped region and lightly-doped region, respectively, and the analytic [...]
