In this works, aluminum scraps powders were mixed with commercial graphite and mechanically alloyed in a high-energy ball mill and subsequently powders sintering. The initial grinding of aluminum scraps for 2 hours and then mixed with commercial graphite powder at a proportion of (y)Al-(x)C (wt%) (x = 1, 5 e 10, 25).…
ZnS nanowires were synthesized in order to investigate $NO_2$ gas sensing properties. They were grown on the sapphire substrate using ZnS powders. SEM (scanning electron microscopy) showed the diameter and length of the ZnS nanowires were approximately in the range of 50 - 100 nm and a few $10s\;{\mu}m$ , respectively…
Studies show that porous titanium alloys improve osseointegration at the implant-bone interface, since they induce new bone tissue formation inside the pores providing a better mechanical stability. In this work, porous Ti-35Nb samples were manufactured by powder metallurgy for orthopedic implant application. The tita…
The high-temperature creep behaviour of drawn copper wire was studied by different constant stresses 98,108 and 118 MPa and under the temperatures of 250, 290 and 340°C. This study deals with the creep based prediction modelling of an industrial copper wire. The proposed unified creep damage constitutive equations wer…
Resumen-Este trabajo de investigacin pretende estudiar el efecto del agua de mar en las propiedades mecnicas de un nuevo biocomposite. Dicho material se ha fabricado mediante el proceso de infusin de una resina bioepoxi (SuperSap) reforzada con fibra natural de camo tipo "mat". Para el estudio, se sumergi en agua de m…
GAMMA-RADIATION synthesized silver/poly(vinyl pyrro-lidone) (Ag/PVP) nanocomposite films were prepared using PVP as a stabilizer. The prepared films were characterized by Ultra Violet/ Visible (UV/vis) spectroscopy, Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD) and Fourier Transform Infera Red (FTIR)…
POLYPROPYLENE FIBERS (PP) grafted with poly acrylic acid (PAAc) were prepared under the effect of gamma irradiation to be used as an adsorbent matrix for Co2+ and Ni2+ ions from aqueous solutions. The different factors which affect the grafting process such as grafting solution, inhibitor concentration, irradiation do…
Poly(lactic acid) (PLA)-based nanocomposites filled with graphene nanoplatelets (xGnP) that contains epoxidized palm oil (EPO) as plasticizer were prepared by melt blending method. PLA was first plasticized by EPO to improve its flexibility and thereby overcome its problem of brittleness. Then, xGnP was incoporated in…
A polystyrene (PS)-anchored Pd(II) metal complex was synthesized on cross-linked polymer by heating a mixture of chlorometylated polystyrene with phenyldithiocarbazate and carbon disulfide in the presence of potassium hydroxide (KOH) in dimethylformamide (DMF). The reaction mixture was heated at 80 °C to form the corr…

Pomiar i rejestrację temperatury zrealizowano za pomocą mikroprocesorowego rejestratora współpr…
본 연구에서는 LTA, FAU, CHA, RHO 제올라이트 분체 9종의 298.15 K에서의 수증기 흡착 특성을 고찰하여 구조, Si/Al 몰 비, 양이온 종류가 제올라이트 분체의 수증기 흡착에 미치는 영향을 고찰하였다. 수증기 흡착량은 $RHO < CHA{\approx}LTA < FAU$ 제올라이트 분체 순으로 증가하였다. FAU 제올라이트 분체의 경우, Si/Al 몰 비가 작은 NaY 제올라이트 분체가 13X 제올라이트 분체에 비하여 우수한 수증기 흡착량(406 mg/g)을 보였다. LTA 제올라이트 분체의 경우, Ca로 치환 5A 제올라이트 분체가 3A, 4A…
In this work, CdS thin films produced by ultrasonic spray pyrolysis technique. The optical properties of CdS thin films were investigated using spectroscopic ellipsometry and UV-VIS Spectrophotometer. The optical properties of CdS thin films coated glass substrates were evaluated by variable-angle spectroscopic ellips…
En el presente trabajo se hace un estudio teórico de la resonancia ferromagnética en una válvula de espín. Para ello, se propone un modelo fenomenológico de la densidad de energía libre de Helmholtz que toma en cuenta la anisotropía magnetocristalina, la anisotropía de forma, el acoplamiento de intercambio intercapa y…
