In this paper, electroless-NiB film was deposited on insulator/Si activated with PdCl2as the barrier layer to prevent the diffusion of Cu into Si. This was done without any conventional pretreatment as modified by self-assembled monolayer (SAM). The results show that the NiB layer is highly uniform and the defects of…
Significance and Use 3.1 This test method may be used to determine the specific core loss, specific reactive power, specific exciting power, inductance permeability, and impedance permeability of flat-rolled magnetic materials over a wide range of inducti
Significance and Use 5.1 The mechanical performance of welded thermoplastic structures is largely dependent on the quality of the welding operation. It is necessary for fabricators to determine that the proper welding procedures are being followed and tha
Cover: The modification of polyolefin surfaces during injection molding reveals positive results, especially using liquid modifiers.By varying the injection parameters, such as mold temperature and injection speed, polyolefin parts possessing high surface energies and bondings with high shear strengths are generated.F…
With the rapid development of the semiconductor filed, more and more challenges have been put forward to the packaging materials as well. Epoxy molding compound (EMC) as one the most important packaging material with the monopoly position was required for low water absorption, high adhesion, and low internal stress an…
Speciality chemicals company Lanxess Deutschland GmbH reports that for the first time in Europe its fouling-resistant membrane technology is being used on a large scale – at the Dammweg thermal power station in Chemnitz, Germany.
Aντικείμενo της Διδακτορικής Διατριβής είναι η θεωρητική και πειραματική διερεύνηση θεμάτων που αφορούν στο σχεδιασμό των μιγμάτων, στην παρασκευή και στον έλεγχο του νωπού και σκληρυμένου Αυτοσυμπυκνούμενου Σκυροδέματος (ΑΣΣ). Μελετήθηκαν θέματα σύνθεσης και ρεολογίας και η επιρροή μεταβολών στη σύνθεση ΑΣΣ στα μηχαν…
Electrospinning as a simple and effective method for preparation of nanofi brous materials have attracted increasing attention during the last two decade [6]. Electrospinning process, unlike the conventional fi ber spinning systems (melt spinning, wet spinning, etc.), uses electric fi eld force instead of mechanical f…
A weekly roundup of information on newly offered instrumentation, apparatus, and laboratory materials of potential interest to researchers.
Juan Zhang, Min Li, Zhihong Liu, Lili Wang, Yongjun Liu, Na Zhang School of Pharmaceutical Science, Shandong University, Ji’nan, People’s Republic of China Purpose: N3-O-toluyl-fluorouracil (TFU) is a potential antitumor prodrug of 5-fluorouracil (5-FU), but its poor solubility has limited its use in clinic. This stud…

Hypertension, a cardiovascular disease characterized by high blood pressure, affected 25.8% of American adults in 2008 (59.4 million people). Hypertension is associated with increased vascular stiffness, which historically has been thought to be caused by vascular adaptation to increased pressure. More recently, human…
Παλαιότερες βιβλιογραφικές αναφορές αναδεικνύουν την καλύτερη κινηματική και λειτουργικότητα του ισχίου μετά από αρθροπλαστική επιφανείας σε σχέση με συμβατικές αρθροπλαστικές ισχίου. Επιπλέον οι επεμβάσεις αναθεώρησης στις αρθροπλαστικές αυτές είναι τεχνικά ευκολότερες με καλύτερα αποτελέσματα λόγω του οστικού εδάφου…
At temperatures above 1200°C, ingested sand and debris particles melt on the TBC surfaces of aero-engine combustion chamber parts and form calcium-magnesium-alumino silicate (CMAS) deposits. The composition and melting point of CMAS vary according to the source and location of the sand and debris. A damage assessment…
Des de fa relativament poc temps, els materials polimerics han trobat una gran varietat d’aplicacions en forma de films obtinguts a partir d’extrusio. Donat que aquets presenten un gran nombre de propietats, cada vegada mes es busquen aplicacions d’alt valor afegit per aquets tipus de material. Pero per aixo cal estud…
At present, coating and coating-like process act as common methods of synthesizing particles, which usually have high utility consumption thus have high cost. Besides, the waste solution from the coating or coating-like processes needs further treatment to avoid hazards emission to the environment. In this study, a no…
Environmental pollution is a significant concern because of human and industrial discharges. Rapid and accurate detection of a pollutant is of the utmost importance in determining its health concern and environmental impact. This detection could be achieved through the development of a facile and hence broadly deploya…
10th International Symposium on the Characterization of Porous Solids, Granada, Spain, 11-14 May 2014
Formation of bismuth-based high-Tcsuperconducting ceramics 2212 and 2223 with partial replacement of Bi by p-elements of group III (Ga, In), IV (Ge, Sn, Pb) or V (Sb) was studied. XRPD, DTA/TG, SEM/EDX, SQUID, and VSM were used for phase identification, structural analysis, grain morphology studies, chemical analysis…
Heavy metal pollution has been a recent topic and low cost adsorbents have been a trend to treat and remove heavy metals from waste water. The discovery of geopolymers has been a breakthrough in the field due to its amorphous and porous structure. The objectives of this research are to synthesize and characterize the…
