ПОЛИМЕРНО–ПОЛИМОРФОИДНАЯ ПРИРОДА СТАРЕНИЯ СТЕКЛА

Based on the concept of polymeric−polymorphous structure of glass and glassforming liquid (Minaev, 1987) experimental data have been analyzed revealing the nature of glass aging. We show that the glass forming substance is a copolymer consisting of structural nano-fragments (polymorphoids) in different polymorphous modifications (PM) of the material having no translational symmetry (long-range order). The study revealed that the process and degree of glass aging influences the properties of glasses, including a change in enthalpy, manifested in the exothermic and endothermic effects observed in thermograms of differential scanning calorimetry of heated and cooled glasses. We have shown that the physicochemical essence of aging is the transformation of polymorphoids from high−temperature PM (HTPM) into low−temperature PM (LTPM) which results, under certain conditions, in LTPM crystallization.На основе концепции полимерно-полиморфоидного строения стекла и стеклообразующей жидкости (В. С. Минаев, 1987 г.) проведен анализ экспериментальных данных, раскрывающих природу старения стекла. Показано, что стеклообразующее вещество представляет собой сополимер, состоящий из нанофрагментов структуры (полиморфоидов) различных полиморфных модификаций (ПМ) данного вещества, не имеющих трансляционной симметрии (дальнего порядка). Выявлено, что процесс и степень старения стекла влияют на свойства стекла, включая изменение энтальпии, проявляющееся в экзо- и эндотермических эффектах, наблюдаемых на термограммах дифференциальной сканирующей калориметрии, нагреваемого и охлаждаемого стекла. Установлено, что физико-химической сущностью процесса старения стекла является процесс превращения полиморфоидов высокотемпературной ПМ (ВТПМ) в полиморфоиды низкотемпературной ПМ (НТПМ), заканчивающийся при определенных условиях кристаллизацией НТПМ

А не пора ли вернуться к Tg Таммана?

Based on the analysis of numerous experimental data shows that the generally accepted today, the glass transition temperature Tg is not. It was the result of borrowing from tammana symbol Tg, is meant the temperature of viscous flow liquid transformation into solid brittle glassy state, and use it together symbol Tw, means the temperature tammana bend on the dependence of the «property-temperature» glass-forming substances above Tg of tammana. On the basis of the application of polymer-polymorphing representations of the structure of glass-forming substances are disclosed physico-chemical nature of the temperature curve Tw (conventional Segodnya), which is the temperature of the reverse direction interconversion of nanofragments patterns (polymorphical) high and low temperature polymorphs that coexist in the vitreous substance. The discovery in recent decades prezentatsionnogo effect located as tammana Tg, is below the standard Tg, Tg confirms the truth of tammana characterized by increasedspecific heat of the heated glass.На основе анализа многочисленных экспериментальных данных показано, что общепринятая сегодня температура стеклования Tg таковой не является. Она возникла в результате заимствования у Г. Таммана обозначения Tg, соответствующего температуре превращения вязкотекучей жидкостив твердое хрупкое стеклообразное состояние, и использования его вместо обозначения Tw. Последнее соответствовало у Г. Таммана температуре изгиба на зависимости «свойство— температура» для стеклообразующего вещества, расположенной выше TgТаммана. На основании применения полимерно-полиморфоидных представлений о строении стеклообразующего вещества раскрыта физико-химическая сущность температуры изгиба Tw (общепринятой сегодня Tg), являющейся температурой реверса направления взаимопревращения нанофрагментов структуры (полиморфоидов) высоко- и низкотемпературной полиморфных модификаций, сосуществующих в стеклообразующем веществе. Открытие в последние десятилетия предэндотермического эффекта, расположенного, как и Tg Таммана, ниже общепринятой Tg, подтверждает истинность Tg Таммана, характеризуемой увеличением удельной теплоемкости нагреваемого стекла

Photocatalytic performance of V\u3csub\u3e2\u3c/sub\u3eO\u3csub\u3e5\u3c/sub\u3e nanoparticles incorporated TiO\u3csub\u3e2\u3c/sub\u3e nanotubes as a visible-light active photoelectrodefor water splitting

Herein we demonstrate brief investigation results of photoelectrochemical performance of TiO2 nanotube (NT) based photoelectrode incorporated with V2O5 nanopaerticles (NP). Photoelectrodes were composed of TiO2 NTs with a diameter of 100 nm and length of 8µm,that were prepared by electrochemical anodization process at 35V in a formamade based electrolyte. The V2O5 nanoparticles were formed on the walls of the TiO2 NTs by deep coating technique with an average size of ∼5-10 nm. The V2O5NP incorporated TiO2NTs show superior light absorption properties in the visible light region up to ∼600 nm compared to the pristine TiO2NTs. It was found that V2O5 NPs formed vanadium impurities within TiO2 NTs which in its turn ceated acceptor levels of V3+ ions in the TiO2 NTs located deep in the forbidden band gap and provided additional absorption properties of visible light. These impurity levels also provide fast recombination sites of electrons and holes formed by photon excitation

Asymptotics of solutions and numerical simulation of the nonlinear heat conductivity problem with absorption and variable density

In the present work, the asymptotic behavior of the solutions of the nonlinear variable-density thermal conductivity problem with absorption is obtained. The critical value parameter is considered. The resulting asymptotics was used as an initial approximation, numerical calculations were performed. As a difference scheme, a three-layer difference scheme was used, which, unlike a two-layer scheme, has greater accuracy
