摘要： The invention provides a method of preparing pure precious metal nanoparticles of controlled sizes and having (100) facets, wherein a precursor substance contained in a reagent solution is subjected to a reduction reaction using a reducing agent contained in the reagent solution to provide nanoparticles, and the reduction reaction is stopped by rapid lowering of the reaction solution temperature. In the process of the invention, the need to use surfactants or other organic particles to stabilize the (100) facets is eliminated.

摘要： The invention refers to a chamber for measurements of electrical properties of reactive powder or liquid samples, allowing the measurement of various electrical parameters to be carried out. The present invention provides the chamber in two variants of embodiment: the multiple use chamber and the single use chamber. The construction of the chamber provides the possibility of carrying out the measurements with the sample placed directly between parallel active surfaces of the electrodes placed coaxially and sliding in a precise manner in to a thin-walled cylinder made of insulating material providing electric insulation. Elements remaining in contact with the sample are made of chemically inert materials. Additionally, a module containing a pair of the electrodes and the cylinder made of insulating material is detachable from the rest of device elements, that enables its loading and hermetic closure in a glovebox filled with inert gas. The device provides the possibility of carrying out the electrochemical measurements as a function of temperature and pressure. The present invention also refers to a method of carrying out measurements of electrical properties of reactive powder or fluid samples, wherein a sample is loaded into a measurement chamber in an inert gas atmosphere, then the gaseous phase is removed from spaces between parallel active surfaces of electrodes and additionally, solid samples are subjected to compression, and then in the system of regulated temperature and/or pressure a measurement of a selected electrical parameter as a function of time and/or temperature and/or pressure is carried out.
摘要翻译：本发明涉及用于测量反应性粉末或液体样品的电性能的室，允许测量各种电参数。本发明在两个实施例的变型中提供了腔室：多用途腔室和单用腔室。室的结构提供了将样品直接放置在同轴放置的电极的平行有效表面之间并以精确的方式滑动到由提供电绝缘的绝缘材料制成的薄壁圆筒中的样品进行测量的可能性。与样品接触的元素由化学惰性材料制成。此外，包含一对电极和由绝缘材料制成的圆筒的模块可与其余装置元件分离，这使得其能够在充满惰性气体的手套箱中装载和密闭封闭。该装置提供了作为温度和压力的函数进行电化学测量的可能性。本发明还涉及对反应性粉末或流体样品的电性能进行测量的方法，其中将样品在惰性气体气氛中装载到测量室中，然后将气相从平行的活性表面电极，此外，固体样品经受压缩，然后在调节温度和/或压力的系统中，执行作为时间和/或温度和/或压力的函数的所选择的电参数的测量。
