GO was supplied from institute of coal chemistry (Shanxi, China).
Results and discussion The evolution of structure, morphology and thermal property of GNPC were investigated by powder X-ray diffraction, scanning electron microscopy and TGA.
After composited with GO, GO@ZIF-8 retains a typical crystal morphology similar to that of the parent ZIF-8 (Fig. 2b), suggesting that the GO just attaches on the ZIF-8 and the precursor still remains the crystal structure of ZIF-8.

Recently, modified polymers containing different additives have been used to change the properties of the polymer structures being printed.
Nonetheless, we speculate that specialized printing patterns, methods, or future resolution enhancements may allow for nano- to meso-porous structure or void formation in “printed” materials.

According to XRD analysis, all samples obtained during microwave-assisted synthesis both in the presence and in the absence of ammonium fluoride in reaction mixtures are single phase anatase powders with particle size 10–15 nm (tetragonal structure, space group I41/amd, lattice parameters a = 3.784 Å and c = 9.514 Å [17]).
The interplanar distances and diffraction ring intensities derived from the SADP unambiguously pointed to anatase crystal structure [19] of TiO2 film.

The importance of hydrogen peroxide as an analyte is dominated by its application in clinical chemistry [2].
The chemical structure of mb is shown in Fig. 1 [5].
Catechol is an important phenol compound, and the measurement of catechol is often related to the brain chemistry.
Fig. 1 Chemical structure of mb, the two oxazolone rings are labeled OxaA and OxaB.
Conclusions The development of mimetic peroxidase is a focus in chemistry, aiming to synthesize a sort of organic complex with not only functions of enzymes but advantages over bioenzymes’ excessive sensitivity to the environment.

Introduction The field of nanostructured materials is a fascinating area of chemistry and materials science because of their novel properties that differ from those of bulk materials and potential applications ranging from mesoscopic research to the development of nanodevices [1-2].
One-dimensional (1D) materials are an important category of nanostructured materials and have been widely researched yielding various special structures such as nanotubes, nanorods, nanowires and nanobelts etc [3-6].
These zinc oxide nanorods or nanobelts reported previously had high purity and well-crystalline structure, but the growth temperature was too high to allow to be used as low-temperature-endurance substrates.
Experimental All the reagents are analytical pure from shanghai chemistry and were used without further purification.
The variation of relative intensity for the peaks may frequently happen for nanoscale structures because of the size-effect and disorder arising from nanostructures.

However, the hotspot formation mechanism, i.e. why chemistry is localized, has not been fully established at the atomic level.
Such shock chemistry enhancement is due to momentum/energy focusing although no jetting was observed [15].
These results provide useful insights in understanding shape-dependent shock chemistry during void collapsing.
