“…Введение в состав керамической массы отощителя с повышенным содержанием глинозема (А1 2 О 3 > 70 %) снижает содержание SiO 2 , что уменьшает содержание количества муллита (3Al 2 O 3 •2SiO 2 ), а оставшаяся некоторая часть Al 2 O 3 выделяется в виде корунда [1,8,[10][11][12][13][14][15][16]. Именно муллит и в большей степени корунд способствуют повышению технических свойств керамических изделий.…”

Object of research: acid-resistant tiles obtained on the basis of unenriched kaolin and waste of non-ferrous metallurgy - slag from the production of metallic chromium, non-ferrous metallurgy wastes occupy the second place after chemical production waste in terms of the amount of especially harmful various pollutants. Various environmental pollutants, such as dust and slag, containing very harmful substances (especially hexavalent chromium, antimony, arsenic, lead and mercury) have a very negative impact on the health of people living within a radius of 50 km from metallurgical plants. The use of large-tonnage waste of non-ferrous metallurgy - aluminum-containing slag from the production of metallic chromium in an amount of 40 % allows to obtain acid-resistant tiles with high physical, mechanical and chemical parameters at a firing temperature of 1300 °C and reduce environmental stress in the area of non-ferrous metallurgy production. Studies have shown that it is impossible to obtain acid-resistant tiles from non-enriched kaolin clay containing less than 18 % A12O3 even at a firing temperature of 1300 °C. The introduction of an optimal amount of chamotte (40 %) into the ceramic mass allows to obtain acid-resistant tiles that meet the requirements of GOST for physical and mechanical parameters at a firing temperature of 1300 °C. The use of aluminum-containing slag from the production of metallic chromium in ceramic compositions in an amount of 40 % (as well as chamotte) allows to obtain products with high physical, mechanical and chemical parameters at a firing temperature of 1250 °C. The introduction of alumina-containing aluminum-containing slag from the production of metallic chromium into the compositions of ceramic masses contributes to the formation of corundum. Corundum is characterized by high chemical resistance to acidic and alkaline reagents. At this temperature, even HF practically does not affect it.

“…Plasmonic materials are well-known for their harsh interaction with free electrons and incoming photons. Thus, metallic materials can function as a source in order to convert the light into a local electric field in metals, named surface-localized plasmonic [17][18][19][20]. These interactions can also be tuned by modifying the morphological properties and the diameter size of the metal nanostructures.…”

Laser Ablation - Applications and Modeling

Pulsed laser ablation in liquids (PLAL) is a physical method that is applied for the fabrication of noble metal nanostructures with different optical and morphological properties. The physical mechanism of laser ablation in liquid environment, the subsequent growth of nanostructures, the essential laser technological parameters that determine the nanostructures’ properties, and the liquid medium’s influence are discussed. The main advantages and disadvantages of the PLAL method are noted. Post-ablation treatment at optimal laser wavelength, fluence and duration of exposure has been indicated as a means of mitigating and overcoming the latter. The aging effect of the colloids and some applications of them are also marked. The most commonly used methods for studying the nanostructures’ characteristics such as UV/vis spectroscopy, high-resolution scanning transmission electron microscopy (HR-STEM), mass spectrometry (MS) and X-ray diffraction (XRD) are commented.

Metal nanomaterials with special physicochemical and plasmatic properties have a wide range of applications in various fields including catalysts, plasmon devices, spectroscopy, fuel cell, and various sensors including chemical, colorimetric, and fluorescence sensors. These applications are made possible by controlling the morphology and properties of nanostructures and increasing their selectivity. Various methods have been developed for the synthesis of metal nanostructures, including the use of prefabricated patterns or hard templates such as anodic aluminum oxide and soft molds such as cetyltrimethylammonium bromide (CTAB).
