An alloy of A1-8wt% Si-0.8wt% Fe was cast in a metallic die, and its microstrucmral changes due to Ti-B refiner and Sr modifier additions were studied. Apart from usual refinement and modification of the microstructure, some mutual influences of the additives took place, and no mutual poisoning effects by these additives, in combined form, were observed. It was noticed that the dimensions of the iron-rich intermetallics were influenced by the additives causing them to become larger. The needle-shaped intermetallics that were obtained from refiner addition became thicker and longer when adding the modifier. It was also found that a-Al and eutectic silicon phases preferentially nucleate on different types of intermetallic compounds. The more iron content of the intermetallic compounds and the more changes in their dimensions occurred. Formation of the shrinkage porosities was also observed.

Lots of studies have been conducted on the optical properties of gold nanoparticles in the first region of near infrared（650 nm–950 nm）, however new findings show that the second region of near-infrared（1000 nm–1350 nm） penetrates to the deeper tissues of the human body. Therefore, using the above-mentioned region in photo-thermal therapy（PTT） of cancer will be more appropriate. In this paper, absorption efficiency is calculated for gold spherical and rod-shaped nanoshells by the finite element method（FEM）. The results show that the surface plasmon frequency of these nanostructures is highly dependent on the dimension and thickness of shell and it can be adjusted to the second region of near-infrared. Thus, due to their optical tunability and their high absorption efficiency the hollow nanoshells are the most appropriate options for eradicating cancer tissues.

A series of novel s-triazolothiadiazoles 3a-h were prepared by condensation reaction of substituted amino triazoles 1a-b with N-phethaloyl-L-amino acids 2a-d in the presence of the phosphoroxy chloride （POC13） as an anhydrous reagent. The structure of all synthesized compounds was confirmed by IR, 1H NMR, arid 13C NMR spectroscopy.

Black phosphorus （BP） has received attention due to its own higher carrier mobility and layer dependent electronic properties, such as direct band gap. Interestingly, the single layer black phosphorus （SLBP） has had large popularity in applications related to thermoelectric, optoelectronic, and electronic devices. Here, we investigate the phonon spectrum, thermal conductivities, and stress strain effects. Robust anisotropy was mainly observed in the thermal conductivities together with the alongside zigzag （ZZ） direction value, compared to the armchair （AC） directions. We also investigated the attitude of stress that was anisotropic in both directions, and the stress effects were two times greater across the ZZ path than those in the AC direction at a low temperature. We obtained a ~oung＇s modulus of 63.77 and 20.74 GPa in the AC and ZZ directions, respectively, for a strain range of 0.01. These results had good agreement with first principle calculations. Our study here is useful and significant for the thermal tuning of phosphorus-based nanoelectronics and thermalelectric applications of phosphorus.

This paper presents a standard scalable and reconfigurable design for testability (SR DfT) in order to increase ac- cessibility to deeply embedded A/MS cores and to limit application of costly off-chip mixed-signal testers. SR DfT is an oscilla- tion-based wrapper compatible with digital embedded core-based SoC test methodologies. The impact of the optimized oscilla- tion-based wrapper design on MS SoC testing is evaluated in two directions: area and test time. Experimental results are presented for several SoCs from the ITC’02 test benchmarks with inclusion of eight analog filters.
