چکیده

The lanthanide pyrochlore oxides $L{n}_{2}{B}_{2}{\mathrm{O}}_{7}$ are one of the most intensely studied classes materials within condensed matter physics, firmly centered as pillars frustrated magnetism. extensive chemical diversity pyrochlores, coupled with their innate geometric frustration, enables realization a wide array exotic and complex magnetic ground states. Thus, discovery new compositions has been persistent theme that continues to drive field in exciting directions. recent focus on mixed $B$-site pyrochlores offers unique route towards tuning both local coordination chemistry sterics, while maintaining nominally pristine sublattice. Here, we present broad overview stability field, integrating synthetic efforts systems historically established families. In parallel, synthesis entire $L{n}_{2}{\mathrm{InSbO}}_{7}$ family ($Ln$ = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) located near boundary using rapid, hybrid mechanicochemical microwave-assisted technique. Magnetic characterization class compounds draws striking parallels stannate analogs, suggesting these may host breadth

Microwave-assisted synthesis of molybdenum oxide nanoparticles

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...

Microwave–Assisted Hydrothermal Synthesis and Optical Characterization of SnO2 Nanoparticles

Semiconductor nanoparticles exhibit size dependent properties due to quantum confinement effect that are not present in their bulk counterparts. In this work, extremely fine and pure SnO2 nanoparticles of ~1.1 nm size were synthesized by a solution process, in which amorphous precipitate of SnO2 was crystallized by microwave heating. The particles sizes varied from ~1.1 to ~2.7 nm. By XRD analy...

Microwave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid

Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.
