The Crystal structure of synthesized samples was determined by X-Ray power diffraction (XRD, Rigaku DMAX IIIC) with a Cu Kα X-ray source (λ= 1.541871 Å).
The diffraction peaks at around 32.5°, 35.5°, 38.7°, 48.7°, 53.4°, 58.3°, 61.5°, 66.2°, 72.4° and 75.2° are associated with (110), (-111), (-202), (020), (202), (-113), (-311), (220), (311) and (004) reflection planes of SnO2 rutile structure, respectively (JCPDS card no. 41-1445) [10].

By one-step co-electrodeposition Hemoglobin (Hb) and Au nanoparticles-chitosan (Au NPS-Chi) nanocomposite film on carbon ionic liquid electrode(CILE), the Hb immobilized with Au NPS-Chi nanocomposite film was stable and retained its functional activity.
Due to the advantages of Hb, such as moderate cost, commercial availability and well-documented structure, Hb is generally used as a model for the direct electron transfer process between redox proteins and the modified electrode in the biological systems.
However, it is difficult to process the electron transfer between redox proteins and electrodes directly, because of its electroactive centers embedded deeply in the protein structure [3,4].

Also, due to the use of O2 or F-based gases in the plasma process,
which cause detrimental loss of Si or SiO2, cleaning processes that only use liquid-based chemistry
formulations have been developed [3] or cryogenic aerosols coupled with liquid cleaning [4].
The residue is completely removed with the cryoaerosol process due to the conditioning of the photoresist with a unique plasma chemistry formulation that allows the clusters to be effectively removed.

However, it is difficult for cellulose to be dissolved in water and most common organic liquids due to the formation of hydrogen-bonded supramolecular structures in cellulose[2].
The FTIR spectra indicated that the molecular structure of original [Bmim]Cl was similar to that of recycled [Bmim]Cl.

Abstract.
With covalent technique, concentrated nitric acid is usually used to treat CNTs, and the conjugated structure of CNTs are destroyed, consequently impairs some of their important properties[4,5].
Then the P(NIPAAm-co-IL) was synthesized by the free radical copolymerization of the ILM and isopropylacrylamide (NIPAAm) using azobisisobutyronitrile (AIBN) as the initiator in methanol at 60 ºC for 20 h, the structure of P(NIPAAm-co-IL) was characterized by NMR (Fig. 2) .

Abstract.
The photochromic properties of the diarylethene derivatives can be improved by modifying the chemical structures upon introducing different substituents or heterocyclic aryl rings.
