NbMoTaW-based refractory high-entropy alloys (RHEAs) are now at the research frontier of advanced metallic materials due to outstanding mechanical properties elevated temperatures. However, poor plasticity RHEAs room temperature hinders further development. The present work proposes a new strategy tailor in-situ forming heterogeneous structures and improve room-temperature RHEAs. A novel series...

Hemopoietic stem cells from human fetal liver were transplanted in utero into preimmune fetal sheep (48-54 days of gestation). The fate of donor cells was followed using karyotype analysis, by immunofluorescence labeling with anti-CD antibodies, and by fluorescent in situ hybridization using human-specific DNA probes. Engraftment occurred in 13 of 33 recipients. Of five live born sheep that exh...

Wound healing is usually facilitated by the use of a wound dressing that can be easily applied to cover the wound bed, maintain moisture, and avoid bacterial infection. In order to meet all of these requirements, we developed an in situ forming biodegradable hydrogel (iFBH) system composed of a newly developed combination of biodegradable poly(ethylene glycol) maleate citrate (PEGMC) and poly(e...

asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...

A novel one-step synthetic route, the double in situ approach, is used to produce both TiO(2) nanoparticles and polymer (PET), and simultaneously forming a nanocomposite with multi-functionality. The method uses the release of water during esterification to hydrolyze titanium (IV) butoxide (Ti(OBu)(4)) forming nano-TiO(2) in the polymerization vessel. This new approach is of general significanc...
