Diels-Alder Cycloaddion in a Low-absorbing Solvent

It has been shown that Monowave 300 is capable of performing reactions in varying scale under identical conditions, providing identical heating profiles in all attempts. Thus, no reoptimization is necessary and once a protocol is elaborated it can be employed in any applicable scale. With an operation range of 2 to 20 mL an initial 10-fold scale up can be accessed with ease. The capability of heating even larger amounts of low absorbing mixtures to high temperatures in no time makes Monowave 300 clearly a valuable tool in method development, opening up new avenues in microwave synthesis.

Formation of CuInS2 Nanoparticles by the Oleylamine Route

Preliminary comparison experiments between microwave and conventional heating under apparently “similar” conditions have provided differently sized and shaped CuInS2 nanoparticles, suggesting the existence of a non thermal microwave effect. However, when repeating those experiments with Monowave 300 and taking advantage of the simultaneous temperature monitoring option, it became evident, that the temperature was not correctly measured in the initially used monomode microwave reactor, which led to wrong assumptions. In fact, no evidence for the existence of a non thermal microwave effect could be found. However, since Monowave 300 represents a highly convenient tool for chemical synthesis and additionally provides accurate temperature measurement, microwave-assisted reaction processing with internal temperature monitoring will be the method of choice for nanomaterial synthesis.

Monowave50教研指南

一份由化学教学领域的专家所撰写的全新的教学研究指南 它将展示如何将回流设备转化为高速的闭管反应，同时为您提供在教学和科研中的众多典型例子。

碳化硅加热管的作用

作为一个非侵入式的替代法，碳化硅已被证实是题号非极性反应物加热能力的理想材料。它能够迅速的吸收微波并转化为热性，并传到给反应物。它可以是微波透明的和弱微波吸收的反应物充分的加热到很高的温度和压力。另外，极高的熔点（2700℃）和非常小的热胀系数是它可以在极高的温度下使用。此外，由于材料内部迅速的温度传导，避免了热岛的出现，从而保证了材料内部均匀的温度分布。

敞口的微波反应器没有任何效果

经常有人宣称，使用微波加热回流的方式，要比电热板加热法更有优势。但是，由于使用微波加热回流和传统加热回流的反应温度相似（受限于溶剂的温度），结果也是相似的。否则，就意味着，微波能对于化学反应存在特殊的效应，我们之前已经讨论过，非热微波效应是不存在的。

碳化氮量子点的合成

量子点最大的优势就是对金属离子的吸收，因此近年来为了找出安全且具有荧光纳米材料同样效果的物质做了大量的研究。 氮化碳被认为是最有希望的材料。但是，它的合成过程中需要较高的温度。另外一个不利因素是，合成的产物容易团聚形成大颗粒，因而荧光性能较弱， 并且水分散性很差。 我们描述了一个简单的合成氮化碳量子点的方法。由于微波辅助合成能够达到较高的温度，并且经过充分的搅拌，能够得到足够小的、均一的粒子。
