Influence of replacing Sr ions by rare-earth ions (RE) ions on the structural and magnetic properties of high coercivity (Hc) SrFe10Al2O19 hexaferrite have been investigated using X-ray diffraction, transmission electron microscopy, differential scanning calorimeter, and SQUID. A 73% increase in intrinsic coercivity is observed for Al doped SrFe10Al2O19 as compared to that of pure SrFe12O19. Th...

Excess molar enthalpies, E H of 1-methyl pyrrolidin-2-one or pyrrolidin-2-one or benzene (i) + oor mor p-chlorotoluene (j) binary mixtures have been measured over entire composition range at 298.15 K using high sensitivity differential scanning calorimeter Micro DSC (Model – μDSC 7 Evo). The E H data have been fitted to Redlich-Kister equation to estimate binary fitting parameters and standard ...

Abstract Understanding the effect of gamma‐ray irradiation on nonisothermal crystallization polymer during cooling is practical importance for applications and manufacturing crystallized polymer. In this work, we expose poly(4‐methyl‐1‐pentene) (PMP) to with different doses study irradiated PMPs. All PMPs exhibit a doublet peak in differential scanning calorimeter thermograms rates range 2.5–20...

The urgent need for reducing the carbon dioxide emissions has led to powertrain electrification at different levels such as hybridization or pure electric vehicles. Despite benefits in terms of local pollution reduction and lower footprint that may be achieved with this technology, new hazards have been introduced. Among them, combustion battery pack due abuse conditions, also known thermal run...

objective(s):drug delivery through the skin can transfer therapeutic levels of drugs for pharmacological effects. analgesics such as nsaids have gastrointestinal side effects and topical dosage forms of these drugs are mainly preferred, especially for local pains. meloxicam is one of nsaids with no topical form in the market. in this research, we attempted to quantify the skin permeation of a m...

In this work, gelatin (G)-polyacrylamide (PAAm)-based interpenetrating polymer network (IPN) hydrogels involving maleic acid (MA) was prepared using by radical polymerization. Full-IPN and semi-IPN were synthesized glutaraldehyde ethylene glycol dimethacrylate (EGDMA) as a crosslinker. The water absorbency of investigated, the values increased with MA G. chemical structures full-IPN tested Four...

In our work, the kinetics of martensitic transformations and influence thermal treatments on transformations, as well related magnetic properties Ni49Mn32Ga19 ferromagnetic shape memory melt-spun ribbons, have been investigated. Thermal at 673 K for 1, 4 8 h can be considered an instrument fine-tuning performance parameters alloys. One-hour promote improvement in crystallinity these otherwise h...

Green electrospun materials are gaining popularity in the quest for a more sustainable environment human life. Bee pollen (BP) is valuable apitherapeutic product and has many beneficial features such as antioxidant antibacterial properties. Alginate natural low-cost polymer. Both show good compatibility with tissues biomedical applications have no toxic effect on environment. In this study, bee...

Lock-in amplifier (LIA) is the most important and essential instrument in signal recovery in the presence of large amount of noise. In this paper an indigenously designed microcontroller based advanced lock-in amplifier is proposed. The lock-in detection is done by quadrature sampling method. It is designed to work for the frequency range of 10Hz to 100kHz. The microcontroller based lock-in amp...

Hydrate-based carbon dioxide (CO2) separation and capture is a new technology for achieving CO2 emission reduction. However, it still not commercially applied the ambiguity of microscopic hydrate formation mechanism. In constant volume experiment formation, there are two or more pressure platforms, indicating that might be different hydrates in succession. order to reveal relationship between p...
