MnBi has attracted much attention in recent years due to its potential as a rare-earth-free permanent magnet material. It is unique because coercivity increases with increasing temperature, which makes it good hard phase material for exchange coupling nanocomposite magnets. difficult obtain, partly the reaction between Mn and Bi peritectic, reacts readily oxygen. MnO formation irreversible harmful performance. In this paper, we report our efforts toward developing To date, high purity (>90%)...
Conductivity dopants are used in organic light-emitting devices (OLEDs) to reduce the operating voltage and consequently improve power efficiency. Here, we report synthesis, as well photophysical electroluminescent properties, of an molecular p-type conductivity dopant: 1,3,4,5,7,8-hexafluorotetracyanonaphthoquinodimethane (F6-TNAP). F6-TNAP was obtained a three-step two-pot synthesis from commercially available octafluoronaphthalene. When 1%−5% coevaporated with...
Developing hierarchical porous carbon (HPC) materials with competing textural characteristics such as surface area and pore volume in one material is difficult to accomplish, particularly for an atomically ordered graphitic carbon. Herein we describe a synthesis strategy engineer tunable HPC across micro-, meso-, macroporous length scales, allowing the fabrication of (HPC-G) both very high (>2500 m2/g) (>11 cm3/g), combination which has not been attained previously. The mesopore alone these...
In this study, we report, for the first time, basic depolymerization of mixed waste polyethylene terephthalate (PET) by hydrolysis and subsequent terephthalic acid monomer recovery with high purity using benign reaction conditions. Several conditions were tested such as PET chip size, concentration aqueous sodium hydroxide (20 or 30%), organic co-solvent (ethylene glycol ethanol), temperature at which was run, duration heating. More importantly, several grades utilized starting materials...
Mechanically alloyed Fe-based alloys with oxide dispersion strengthening have largely dropped out of the marketplace due to high cost related problems complex and unreliable processing. Nevertheless, desirable properties strengthened (ODS) steels motivated research on alternate processing routes aimed at improving simplicity reliability. Powders produced by gas atomization reaction synthesis (GARS) consist stable Fe-Y intermetallic phases a Cr surface layer that acts as chemical reservoir...
We report the design, synthesis, thermal, and photophysical properties of two phosphine oxide based electron transport/hole blocking materials, 2,6-bis(4-(diphenylphosphoryl)phenyl)pyridine (BM-A11) 2,4-bis(4-(diphenyl-phosphoryl)phenyl)pyridine (BM-A10), for blue electrophosphorescent organic light emitting devices (OLEDs). The use these materials in OLEDs with iridium(III) bis[(4,6-difluorophenyl)-pyridinato-N,C2′]picolinate (Firpic) as phosphor was demonstrated. Using dual host device...
MnBi attracts great attention in recent years for its potential as permanent magnet materials. phase is difficult to obtain because of the rather drastic peritectic reaction between Mn and Bi. In this paper, we report our effort on synthesizing high purity compound using conventional powder metallurgical approaches. Neutron diffraction was carried out investigate crystal nuclear structure obtained powder. The result shows that about 91 wt. % at 300 K, magnetic moment atom lattice 4.424 4.013...
An indirect fused deposition process was used to fabricate controlled‐porosity alumina bone grafts using a computer‐aided‐design file created from computed tomography (CT) scans of horse's short pastern bone. Structures with both uniform and gradient porosity were fabricated show the effectiveness this for fabrication custom orthopedic implants. Cytotoxicity cell proliferation studies conducted different lines that these are biocompatible. Uniaxial compression tests also understand influence...
