A novel low-temperature densification method of nanocrystalline calcium hydroxyapatite (HAp) at a temperature as low 200 °C with no liquid additives is investigated. To understand the underlying mechanism sintering hydroxyapatite, two types lab-synthesized HAp, dried (110 °C, 12 h) and calcined (1000 2 h), were subjected to cold conditions (200 500 MPa) compared thoroughly. The samples found be nanocrystalline, enveloped by an amorphous shell, whereas fully crystalline, confirmed X-ray...
We have successfully demonstrated a new method of radioactive waste immobilization by hosting waste-bearing form in another matrix. A cold sintering route was used to consolidate silica-incorporated hydroxyapatite (Si-HAp) composite at 200 °C applying uniaxial pressure 500 MPa for short holding time 10 min. The higher relative sintered density up 98.0 ± 1.3% achieved 25 wt% Si loaded HAp. Results from high resolution X-ray diffraction, micro-hardness, and scanning electron microscopy...
In this work, thermal conductivity and mechanical strength of a commercial epoxy resin were improved by incorporating an amine-terminated oligoimide modified graphene oxide (ATO-GO). For purpose, the surface GO was with flexible/stable imide backbone amine terminals. The ATO-GO incorporated in proportion to prepare series nanocomposites. terminal amino group also acted as curing moiety for leading good interfacial compatibility dispersion matrix resulting properties. cured hardener...
Technetium-99m (99mTc) is an important, short-lived decay product of molybdenum-99 (99Mo), and it considered the backbone modern nuclear diagnostic procedures. Since fission 235U main source production 99Mo, either highly-enriched uranium (HEU) targets or low-enriched (LEU) are irradiated in research reactors. The use LEU being promoted by international community to avoid proliferation issues linked with HEU. In order define waste management strategy at planning stage establishment based...
The current study reports the preparation of thermally conductive polymeric nanocomposites. For this purpose, two epoxy-based nanocomposites were prepared by dispersing a different type functionalized graphene oxide (GO) nanofiller in each series. Both these GO nanofillers covalently bonding oligoimide chains on their surfaces. In one series, reaction 3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA) with diamine 4,4'-methylenedianiline (MDA). While other case, BTDA was reacted...
