Microstructure of a rapidly solidified Al-4V-2Fe alloy has been examined in detail by means of transmission electron microscopy and atom probe field ion microscopy. It is composed of a mixture of α-Al and amorphous phases. α-Al grains are relatively large (400 nm), but nanoscale domains of amorphous phase are trapped in the fcc grains. The interface between the α-Al and amorphous phases are ver...

Transformations accompanying shape-instability govern the morphological configuration and distribution of phases in a microstructure. Owing to influence microstructure on properties material, present work, stability three-dimensional rods ‘representative’ polycrystalline system is extensively analysed. A multiphase-field model, which recovers physical laws sharp-interface relations, includes gr...

Rationale: In the phase III, 52-week ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial chronic obstructive pulmonary disease (COPD) (NCT02465567), triple therapy wi...

The microstructure of grain boundaries (GBs) in the commercial NdFeB-based alloy for permanent magnets has been studied. It is generally accepted that unique hard magnetic properties such alloys are controlled by thin layers a Nd-rich phase Nd2Fe14B/Nd2Fe14B GBs. These GB ensure isolation Nd2Fe14B grains from each other. usually supposed contain metallic Nd or intermetallic compounds. However, ...

Using a panel of monoclonal antibodies against human myoglobin (Mb), we have shown that the sensitivity of antigen-capture ELISA can be significantly increased by simultaneous immobilization of two cooperating capture monoclonal antibodies on a solid phase. This method ("triple-site ELISA") uses three monoclonal antibodies to different epitopes of the same antigen (two capture/one tracer) unlik...

UNLABELLED The diagnostic value of neuroendocrine tumor (NET) imaging using PET with integrated CT is dependent on both components. This retrospective study assessed the value of the single CT phases of a triple-phase (early arterial, portal-venous inflow, and venous) CT protocol in comparison to (68)Ga-DOTATOC PET in a masked reading. METHODS (68)Ga-DOTATOC PET/CT examinations from 51 patien...

the effects of isothermal aging at temperatures between 550-850 ?c for durations of 1-100 h on microstructure, tensile properties, and impact fracture behavior of 316l austenitic stainless steel weld metal have been investigated. for this purpose, various techniques including metallographic observations, measurement of ferrite content using ferritscope, and fractographic investigations have bee...

The Mg2Si intermetallic alloys have been prepared by using a powder metallurgy process. milling treatment of silicon as raw material to improve the formation phase was investigated in this research. un-milled and milled mixed with magnesium for 2 hours. powders were compacted stainless steel tubes sintered at 500 600°C 6 crystal structure identified X-ray diffractometer (XRD), while fracture su...
