The paper investigates the physical and mechanical properties of structures with geometry triply periodic minimal surfaces (TPMS). Test samples were made from polyamide using SLS (selective laser sintering) 3D printing technology, polylactide FDM (Fused deposition modeling) a photopolymer based on acrylates LCD (liquid crystal display) technology; in form cube edge size 30 mm. strength energy-absorbing TPMS-based cellular have been determined. To analyze features samples, skeletal graph...
Triply periodic minimal surfaces (TPMSs) are found in many natural objects including butterfly wings, sea urchins, and biological membranes. They simultaneously have zero mean curvature at every point a crystallographic group symmetry. A metamaterial can be created from such or used as reinforcement of composite material. While TPMS mathematical object has been known since 1865, only novel additive manufacturing (AM) technology made it possible to fabricate cellular materials with complex...
The article presents the method of production foam concrete, as a geonoiseprotective material. Its ability to absorb acoustic energy due porous structure, composition and thickness films is taken into account. Besides that energy-absorbing solid phases stone frame consideration. possibility using this concrete material for reducing noise from railway transport movement shown. Also, takes account geoprotective properties concerning pollution transport.
Geoecoprotective properties of the binder system are discussed in paper. The base such is detoxication environment from heavy metal ions by means reactions with silicate and sulphate calcium. Thermodynamic analysis systems has shown that (HMI) certain building materials provides reduction Gibbs energy value comparing to hydration without HMI. Detoxicating were named mineral geoantidotes (MGA). Estimations processes application examples given.
The article presents 3 new methods of soil simultaneous strengthening and detoxicating. are based on using hydrate complexes obtained by means silica sol, foam concrete phosphates. technologies suggested after named soling, aerating phosphating. level is from 0,2 MPa for soling more than point detoxication to obtain heavy metal ion silicates phosphates with very low solubility product. 1000 TC (tolerable concentration, mg/g).
The authors first examined the possibility of estimating pore space coating intumescent coatings for increase fire resistance building structures using program "Video tests".
Background: Two directions of absorption silica sol usage for construction are shown. The first direction is the by means solution process and second obtaining according to reaction between clay mineral (Al2O3•4SiO2•2H2O) H3PO4 solution. Methods: Thermodynamically-based method research used study soil properties. In addition, experiments were held illustrate quality geoprotection improvement due absorptive properties hydrate silicate building materials products. Findings: First, processes...
In the paper it is shown that quality of concrete articles and structures may be significantly improved by silica sol solution absorption. Improvements include increase compressive strength, resistance to low temperatures, coefficient constructive quality, decrease water sorption, contraction. The reason improvement discussed.
Abstract Hybrid organic–inorganic composites comprising cyanoethyl ester of poly(vinyl alcohol) (CEPVA) and submicron-sized barium titanate with a core–shell structure are studied. For the first time, permittivity obtained was studied in correlation acid–base properties filler controlled via surface modification by formation structures using sol–gel plasma processes. The is found to grow increase content Brønsted basic centers on due enhanced interactions acid groups polymer. This effect...
The point of the paper is to introduce new characteristics underground construction materials which are important for geoecoprotection infrastructure in sense durability and wastewater resistance. main idea using absorption ability constructions on cement base. It was shown that utilization silica sol solution instead water allows one improve more than 50% properties concrete Because technology fabrication base has been suggested (silica technology, SAT - technology). Underground absorb...
Objectives: The objective of this study is to obtain better quality foam concrete. In the process preparing proteinbased technique stabilizing with colloidal sol solutions used. Methods: idea stabilization implies following: interaction at boundaries between layer phase and becomes possible if silica or iron-bearing This results in generating complexes that increase strength concrete slurry thus improve properties resulting Findings: investigates parameters characterize different limitations...
The article analyses 2 kinds of properties silica sol foam concrete: technical and geoecoprotective ones. Foam concrete stabilized with has lower heat conductivity resulting in fuel saving. obtained according to absorption technology water is good enough for blocking prevent the environment pollution. Pollution can be achieved by two methods. first method saturation an affected oil products sol. second create a special preventive protection using screen. shows protein soil systems.
Lithosynthesis is the new method of technical and geoecoprotective properties improvement for cement based construction. The point reactions in pores capillaries artificial mineral stone. classification presented level shown. examples lithosynthesis application are shown with aspect taken into consideration.
Abstract A series of finely dispersed Y
A series of LaF3:Ce3+ phosphors for application in photodynamic therapy are synthesized using a one-stage solvothermal synthesis. The synthesis conditions; type and quantity stabilizer; concentration activator providing the maximum intensity UV- X-ray-excited luminescence; lowest size; highest colloidal stability phosphor nanoparticles found. As result this study, following parameters determined cerium content 5% mol. ethanol as reaction medium polyvinylpyrrolidone stabilizer at an optimized amount.
