The synthesis and the magnetic properties of Sm x BiY2–x Fe5O12 nanoparticles

Efficient and Practical Syntheses of Enantiomerically Pure (S)‐(−)‐Norcryptostyline I, (S)‐(−)‐Norcryptostyline II, (R)‐(+)‐Salsolidine and (S)‐(−)‐Norlaudanosine via a Resolution‐Racemization Method

“…of NaOH at 70 ℃ in aqueous DMSO (DMSO/H 2 O＝10∶1) to give dihydroisoquinolines 6a and 6b by β-elimination. [20] Subsequently, compounds 6a and 6b were reduced by 2.0 equiv. of KBH 4 in methanol to furnish the racemic THIQs (RS)-(±)-1 and (RS)-(±)-2 in 85% and 86% overall yields, respectively.…”

Cerium oxide nanoparticles prepared in self-assembled systems

“…These are known as hydrothermal methods and have been used by many researchers to produce high surface area pure and doped cerium oxides [35][36][37][38][39][40]. Also, cerium oxide can be prepared by pyrolysis (low temperature or spray) [41][42][43][44], thermodecomposition [45][46][47][48], aqueous precipitation using different precipitating agents such as ammonia solution [49,50], hexamethylenetetramine [31,51] or other additives [52][53][54][55][56], solution and solid combustion methods [57][58][59][60][61], mechanochemical methods [62], sol-gel methods [63][64][65][66][67], gas condensation [68], microwave heating [69,70], and sonochemical methods [71] amongst others (see [19]). These methods have been used for preparing not only pure ceria but also doped and mixed cerias.…”

Mg Doping Induced Effects on Structural, Optical, and Electrical Properties as Well as Cytotoxicity of CeO2 Nanostructures

“…CeO 2 nanostructures have received much attention due to their changed and enhanced characteristics as compared to their bulk counterparts. [12][13][14][15] In recent years, several synthetic methods have been used to explore CeO 2 nanostructures fabrication such as the surfactant-assisted approach, [16] micro-emulsion, [17] spray pyrolysis, pyrolysis (low temperature or spray), [18] thermodecomposition, [19] reflex method, [20] hexamethylenetetramine, [21] microwave-assisted heating, [22] chemical co-precipitation, [23] organometallic decomposition, [20] solution and solid combustion methods, [24] sol-gel methods, [25] flow method, [26] hydrothermal synthesis, [27] microwave heating, [28] and gas and sonochemical methods. [29] The chemical co-precipitation technique has several advantages, such as low cost, high reproducibility, versatility, and control over particle sizes and shapes.…”
