Storage in the presence of cetyltrimethylammonium bromide (CTAB) is also essential to prevent their aggregation, which being toxic, needs to be removed before using them for biological applications. We herein, present a simple approach to overcome these limitations through synergistic action of low pH and high temperature. The proposed modifications synthesize highly homogeneous nanorods which are stable upto months even when stored in water.

The crystallite size was obtained by Scherrer equation analysis of XRD main peak of doped and undoped nanoparticles. It was observed that crystallite size of bare TiO2 was 17.00 nm, whilst the crystallite size of 1% Ag doped titania and 2% Ag doped titania was 13.07 nm to 14.17 nm. TEM images ascertained that particle size of Ag-TiO2 nanoparticles were in the range 40-45 nm in length and 10-15 nm in width. The pH of the solution exerted a negative effect on photodegradation rate of sparfloxacin. The masking effect on the degradation of sparfloxacin was observed at higher catalyst dosages. The increase in UV intensity linearly enhanced the degradation rate of sparfloxacin and the influence of initial sparfloxacin concentration on the degradation rate was investigated and discussed.

First, silica nanospheres were self-assembled to form a colloidal crystal template within a mold. The interstitial space of this template was infiltrated by the hydrogel precursors, which were then allowed to polymerize. Upon removal of silica by hydrofluoric acid etching, a photonic crystal film, which produced a pink structural color, was formed. To add a chemical sensing functionality to the film, the molecules to be sensed were mixed with the hydrogel precursors for molecular imprinting; the amino acid proline was used for this purpose. Characterization of the functionalized photonic crystal film was conducted by optical reflectance measurements and imaging. The nanopores were imaged using SEM after cryogenic freezing of the film samples. Chemical sensing of proline was conducted on the film, with the reflectance peak shifting from 650 nm to 795 nm.

Sensors used here is metal-oxide semi-conductor gas sensors and classification is machine learning. After explaining sensing principle, we show the classification results of coffee companies and kinds of coffees. Then their method apply to sensing and classification of human body smell so called Kunkun Body. The Kunkun Body can classify one of three human smells such as sweaty smell, middle-aged smell, and old-aged smell using four smell sensors. To train the Kunkun Body we gathered 2,100 persons who have one of three human body smells. We divide them into three groups according to each smell for human body and divide into 10 classes according to the density levels. The first stage for learning is to train the neural network of competitive learning to chemicals which are main components for human body smells. After pre-learning we settle the final values of weighting coefficients as the initial values. The real data for 2,100 persons are divided three groups for typical each smell and ten levels for strength. If the misclassification does not decrease, we adjust the structure of the neural network by increasing the number of neurons. When we can get high accuracy classification results, those weighting values will be stored and their values are used for Kunkun Body.
