As Henry Kissinger used to say in our White House staff meetings, when discussing economics, "It is with an unaccustomed sense of humility that I address you on this subject." This distinguished group of scholars and practitioners, all pros on the subject of financial restructuring, requires me to approach the subject in the same way. While my background gave me a certain familiarity with the w...

40% of ultrapure silicon is lost as kerf during slicing to produce wafers. Kerf is currently not being recycled due to engineering challenges and costs associated with removing its abundant impurities. Carbon left behind from the lubricant remains as one of the most difficult contaminants to remove in kerf without significant silicon oxidation. The present work enables to better understand the ...

Non-isothermal crystallization of neat high density polyethylene (HDPE), wood flour (WF)/HDPE composite (WPC), virgin Kevlar fiber (KF) reinforced WPC (KFWPC), and grafted Kevlar fiber (GKF) reinforced WPC (GKFWPC) was investigated by means of differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). Several theoretical models were applied to describe the process of nonis...

The hydrothermal synthesis of a mcallisterite (Mg2(B6O7(OH)6)2 · 9(H2O)) mineral at low temperatures was characterized. For this purpose, several reaction temperatures (0-70°C) and reaction times (30-240 min) were studied. Synthesized minerals were subjected to X-ray diffraction (XRD), fourier transform infrared (FT-IR), and Raman spectroscopies and scanning electron microscopy (SEM). Additiona...

Single crystals of melaminium phthalate (MPH) were grown from aqueous solution by slow solvent evaporation method at room temperature. X-ray powder diffraction analysis confirmed that the MPH crystal crystallises in orthorhombic system with space group Pbcn and the calculated lattice parameters were a = 33.559 ± 0.066 Å, b = 10.517 ± 0.057 Å, c = 7.117 ± 0.025 Å, α = 90, β = 90, γ = 90 and V = ...

The characterization of the crystallization kinetics of an amorphous soft magnetic alloy, Fe88Zr7B4Cu1, called NANOPERM, is presented. Vibrating sample magnetometry (VSM), X-ray diffractometry, and differential scanning calorimetry have been used to observe crystallization kinetics. The VSM observations take advantage of the Curie temperature of the amorphous phase c amorphous of the NANOPERM a...

Aluminosilicate gel precursor having mullite composition was synthesized from inorganic salts of aluminum and silicon by employing the sol-gel method. Chemical analysis, surface area and bulk density measurements were performed to characterize the dried gel. The course of the mullitization was examined by FT-IR analysis which confirmed the diphasic nature of the gel. ...

Fe-rich soft magnetic alloys are candidates for applications as sensors and actuators. Spring magnets can be obtained when these added to hard compounds. In this work, two nanocrystalline Fe-Zr-B-Cu produced by mechanical alloying, MA. The increase in boron content favours the reduction of crystalline size. Thermal analysis (by differential scanning calorimetry) shows that, temperature range co...
