A micro-reactor apparatus CdSe: A synthesis method originally reported by Peng et al. [4] was used with modifications.
[10] As ZnS source, dimethyl zinc is commonly used, however, from the view point of safty and low environmenat impact, O'Brien et al. attempted synthesis of core/shell nanoparticles of chalcogenides with single molecular source
Weller et al. and Bawendi et al. showed that only a small amount of ZnS (equal to overcoating with 1-2 monolayers) can give the highest quantum yield. [10] In the extensively adopted method, the coating layer is usually tailored by concentration of raw materials.

Padmini et al. [19] prepared SrTiO3 by the solid-state reaction process and found that the thermal conductivity can be successfully decreased in dysprosium-modified SrTiO3 ceramic powders.
Padmini et al. [19], and H.
Li et al. [21] reported amphoteric incorporation of Gd3+ in BaTiO3 compound ceramics and clarified that the possible occupation of A or B site doping depends on the ionic radius and dopant concentration.
In addition, the pores observed in the ceramic images, especially that in Fig. 5b, could be due to the fast cooling by ventilation as was described by Niesz et al. [28].

The VSS compositions of TWAS was analyzed by an elemental analyzer (Vario EL Ⅲ)[19].
Volatile fatty acids (VFAs, C2 to C5) were determined by gas chromatography with FID (Agilent, 6890) following methods described by Akutsu et al.[19].
The determination flocculation efficiency was the same as described by Kobayashi et al. using polyamidine-base high molecular flocculants for dewatering of sludge[5].
Qiao et al. showed that approximately 72% VSS of the mixture of primary and secondary sludge dissolved into aqueous phase at 170 ℃ with 0.2 g-NaOH/g-SS and 30 min holding time[14].

Emarose et al. [7] discusses the maximum physiological parameters which can measure by means of an oximeter installed on the steering wheel of the car.
For the monitoring of the driver, Geva et al. [8] proposed a system that includes several sensors to monitor the vital signs, connected or integrated at least one element of the vehicle.
Gabaude et al. [9] examine the relationship between mental effort and performance management by making three different measurements: measuring the cardiac activity, the driving performance and the subjective data.
Sun et al. [11] have developed a sensor that can detect ECG signal from a distance of 20 cm to 30 cm away through cloth.
Scully el al. [3] shows that a mobile phone can serve as an accurate monitor for several physiological variables, based on its ability to record and analyze the varying color signals of a fingertip placed in contact with its optical sensor.
