  1. Synthesis and anticoagulant activity of the quaternary ammonium chitosan sulfates.

    International Journal of Biological Macromolecules 50(1):31 (2012) PMID 21996571

    Quaternary ammonium chitosan sulfates with diverse degrees of substitution (DS) ascribed to sulfate groups between 0.52 and 1.55 were synthesized by reacting quaternary ammonium chitosan with an uncommon sulfating agent (N(SO(3)Na)(3)) that was prepared from sodium bisulfite (NaHSO(3...
  2. Dynamic covalent chemistry: Catalysing dynamic libraries.

    Nature Chemistry 2(6):433 (2010) PMID 20489706

  3. Silica nano-particle super-hydrophobic surfaces: the effects of surface morphology and trapped air pockets on hydrodynamic drainage forces.

    Faraday Discussions 143:151 (2009) PMID 20334101

    We used atomic force microscopy to study dynamic forces between a rigid silica sphere (radius approximately 45 microm) and a silica nano-particle super-hydrophobic surface (SNP-SHS) in aqueous electrolyte, in the presence and absence of surfactant. Characterization of the SNP-SHS surface in air show...
  4. In situ control of atomic-scale Si layer with huge strain in the nanoheterostructure NiSi/Si/NiSi through point contact reaction.

    Nano Letters 7(8):2389 (2007) PMID 17604405

  5. The morphology of axial and branched nanowire heterostructures.

    Nano Letters 7(6):1817 (2007) PMID 17489640

  6. Optical properties of a wrinkled nanomembrane with embedded quantum well.

    Nano Letters 7(6):1676 (2007) PMID 17461606

  7. Chemical reaction at specific sites and reaction-induced self-assembly as observed by in situ and real time SANS: enzymatic polymerization t...

    Biomacromolecules 7(9):2479 (2006) PMID 16961307

    We have investigated the self-assembling process of cellulose artificially synthesized via enzymatic polymerization by means of in situ and time-resolved SANS (small-angle neutron scattering). The results elucidated the following: (i) Cellulose molecules synthesized at a special reaction site of the...
  8. In vitro transcription and protein translation from carbon nanotube-DNA assemblies.

    Small 2(6):718 (2006) PMID 17193110

  9. Variable size and shape distribution of ferroelectric nanoislands by chemical mechanical polishing.

    Small 2(4):500 (2006) PMID 17193074

  10. First fluorescent sensor for fluoride based on 2-ureido-4[1H]-pyrimidinone quadruple hydrogen-bonded AADD supramolecular assembly.

    Journal of Organic Chemistry 71(5):2143 (2006) PMID 16497005

    A simple, highly selective, neutral, fluorescent sensor for fluoride anions is reported. It is based on 2-ureido-4[1H]-pyrimidinone quadruple hydrogen-bonded AADD supramolecular assembly, and its assembling and disassembling processes are also able to respond to external stimuli reversibly.
