In her article "Genocidal Rape, Enforced Impregnation, and the Discourse of Serbian National Identity" Tatjana Takševa analyzes two main processes which contributed to the systematic rape and enforced impregnation of Bosniak women during the Balkan conflict: the discourse of Serbian nationalism articulated in response to the sexual violence that took place in Kosovo preceding the war and the si...
Nanocrystallized ceria-based coatings were prepared on TA6V titanium alloy by using a three-step procedure: substrate pretreatment, electrochemical impregnation and final heat treatment. UV–vis and Raman in situ spectroscopies performed at the substrate interface during the electrochemical impregnation, showed experimentally for the first time that the interfacial deposit is made up of cerium h...
In order to enhance bioactive functionalities of ginseng, an acid impregnation processing was applied as a pre-treatment in producing red ginseng. Acid impregnation studies were conducted, and acids (ascorbic, malic, and citric acid) were selected. The optimal concentration of each acid was investigated in this study in terms of ginsenoside contents. The most concerned ginsenoside, Rg3 was incr...
The effect of modifying additive (La2О3) on the activity Ni-Co oxides was studied for dry reforming methane (DRM). catalysts were prepared by impregnation granulated diatomite (D) and characterized SEM, EDX, H2-TPR, XRD, AES. It is shown that addition 1.5 wt.% La2O3 into Ni-Co/D composition leads to an increase in catalyst, providing a conversion close under thermodynamic equilibrium conditions...
The physical and chemical properties of tungsten oxide supported on SBA-15 mesoporous silica prepared by a controlled grafting process through atomic layer deposition (ALD) were studied using complementary characterization methods. X-ray diffraction, optical absorption, and transmission electron microscopy showed that tungsten oxide species are highly dispersed on SBA-15 surfaces, even at 30 wt...
Preparation and High-Throughput Testing of TiO2-Supported Co Catalysts for Fischer‒Tropsch Synthesis
A series of Co/TiO2 catalysts was tested in a parameters field study for Fischer‒Tropsch synthesis (FTS). All were prepared by the conventional impregnation technique to obtain an industrially relevant Co content 10 wt % or 20 %, respectively. In summary, different TiO2 pure anatase phase, rutile as well mixed and phase used supports. Performance tests conducted with 32-fold high-throughput set...
In order to visualize the distribution pattern of the neuronal bodies and neurofibrils in the honeybee brain, we adapted a metallic impregnation technique first described for vertebrate nervous system by Ramón y Cajal. The honeybee brain constitution plays a key role in the development of learning and memory capacities. The general characteristics observed in the honeybee brain, stained by meta...
Division of Biomedical Sciences (Anatomy) St George's, University of London London, UK ABSTRACT: The standard method for plastination with Biodur TM S10/S3 involves lowtemperature dehydration in a volatile intermediary solvent followed by forced impregnation under vacuum at -15°C. However, some institutions have been reluctant to install low-temperature impregnation equipment because of health ...
The evolution of laws on the use of biocide products has led to important changes in the field of wood preservation leading to an increasing interest for non “biocidal treatments” like thermal or chemical modifications. While thermal modifications become more and more common on industrial scale, development of chemical modifications progresses slowly. One reason for the challenges encountered i...
The highly ordered mesoporous silica SBA-15 was successfully synthesized and incorporated with iron, aluminum, and zinc oxides by use of an incipient wetness impregnation technique. Aluminum 10% impregnation was safely incorporated by an incipient wetness impregnation technique for SBA-15, which had 638.75 m/g of BET surface area and 48 Å of pore diameter, without producing clogging of pore str...
