Abstract :
Photocatalytic technology is considered as one of the most attractive and promising technologies to directly harvest, convert and store renewable solar energy for generating sustainable and green energy and a broad range of environmental applications. However, the use of a photocatalyst in powder or coating forms restricts its applications due to its disadvantages, such as difficulty in recovery of nano-powder, secondary pollution, low adhesion between photocatalytic coating and substrate material, short service life of photocatalytic film and so on. The investigation and application of photocatalytic glass-ceramics (PGCs) in water purification, bacterial disinfection, self-cleaning and hydrogen evolution have received extensive attention due to their inherent advantages of low cost, easy fabrication, transparency, chemical and mechanical stability. Real-time solutions to energy shortage and environmental pollution faced by the development of human society can be provided by rationally designing the chemical composition and preparation methods of glass ceramics (GCs). This review introduces the concept and crystallization mechanism of PGCs and expounds on the basic mechanism of photocatalysis. Then, the key point difficulties of GCs' design are discussed, mainly including the methods of obtaining transparency and controlling crystallization technologies. Different modification strategies to achieve better photocatalytic activity are highlighted. Finally, we look forward to further in-depth exploration and research on more efficient PGCs suitable for various applications.

Abstract :
Different heating treatments with the variation of heating rates, holding temperatures and holding time were used to simulate the LTPS procedure. The experimental results show that the reheating shrinkage rates of glass substrates are rarely changed with increasing the heating rate, but strongly enhanced by raising the holding temperature and time, which shows that the reheating shrinkage of glass is closely related to heat treatment and structural relaxation. The production process of glass is critical to the reheating shrinkage of glass.

Abstract :
The paper describes a multi-step chemical ion exchange method, also known as "Kailly Method", to increase the impact resistance of Na2O-Al2O3-SiO2 based glasses and derivatives. The chemical strengthening methodology comprises of three steps where the first step is a chemical ion-exchange process (labeled as IOX1) in KNO3 melt followed by a second step involving high temperature ion migration (HTIM), and the final step of another chemical ion-exchange (IOX2) step in KNO3 melt. The effect of the proposed strengthening mechanism on fill compressive stress layer depth (DOL), diffusion coefficient (D) and surface compressive stress (CS) of a glass with composition 16.11 Na2O-1.47 K2O-2.73 MgO-20.02 Al2O3-59.08 SiO2-0.1 CaO-0.49 SnO2(wt.%) has beet evaluated. The results show that the "Kailly Method" can promote a DOL to 120-150 mu m which is 50-80% higher than the conventional one-step ion exchange process. The distribution of compressive stress has been positively correlated with K+ concentration and modulus of elasticity. Further the impact strength of a 0.5 mm thick glass specimen has been demonstrated to be linearly related to the compressive stress and the square root of DOL thus indicating that the increase of DOL on the glass surface contributes to the improvement of impact resistance.

Abstract :
A series of catalytic coatings consisting of MnOx-CeO2 and TiO2 support were prepared by atmospheric plasma spraying, which was aimed at the application of selective catalytic reduction (SCR) of NOx. The effect of the load of active component on the coating was firstly studied. The results showed that all the coating presented the highest catalytic activity at approximately 350 degrees C and the coating with the composition of 20MnO(x)/5CeO(2)/TiO2 (wt%) achieved the most powerful performance. The coating was then prepared on a wire-mesh structure substrate, which can be easily assembled as a gas filter. The results showed that the specific surface area was greatly increased resulting in the significant improvement of the catalytic activity of the coating. This strategy offered a promising possibility of removing NOx and particulate fliting simultaneously in industrial applications.

Abstract :
In this work the effect of argon filling ratio and air space thickness on the heat transfer coefficient of double-glazing was studied. The heat transfer coefficient of double-glazing was measured by heat flow meter method (based on standards ISO10291, ISO 10292, ISO8301 and DIN EN 12939), during this process the testings of argon filling ratio and emissivity of coated glass surface were involved. For the thermal performance of double-glazing, the influence of various factors on heat transfer coefficient was analyzed. The comparison was conducted between coated double-glazing (one glass pane coated with low-emissivity) and non-coated double-glazing. Within the thickness of air space in the range of 9-18 mm, the higher the air space thickness, the higher the filling ratio of argon gas, the better the thermal insulation performance achieved. Under the same gas filling ratio, the heat transfer coefficient of coated double-glazing (emissivity is 0.13) which is much lower than that of non-coated double-glazing, can effectively meet the requirement of building energy efficiency in China.

Abstract :
This paper described three methods for measuring high temperature resistivity of glass including their basic principles, advantages and disadvantages so as to provide a reference for measurement. The effects of electrode and voltage on high temperature resistivity were studied. Accuracy of measurement results of plate electrodes is better than wire electrodes. The resistivity of molten glass decreased with increasing AC voltage. Measurement results are stable when the voltage is less than 10 V, but when the voltage exceeds than 40 V, Joule heating effect will be generated resulting in smaller measurement values. In addition, high alkali aluminosilicate glass as object is used to introduce test procedure of temperature resistivity and explore the relationship between high temperature resistivity and alkali metal. Results show that high alkali aluminosilicate glass resistivity decreases with increasing temperature, and the effect of K2O on high tempearature resistivity is more pronounced. © 2016 Trans Tech Publications, Switzerland.

Abstract :
In this paper, shale and feldspar were regarded as matrix materials and sillcon carbide was added as foaming agent. After a quality ratio of walnut shell was mixed with as pore-forming agent, porous insulation materialswere made through high temperature foaming. The firing curve was developed by studying the thermal history. XRD and micro-morphology were used to study the effects of the amount of walnut shell on the density, thermal conductivity and mechanical properties of the products. The results show that when the amount of walnut shell was 10%, the sample density was 180 kg/m(3), and the flexural strength and compressive strength could reach 1.031 MPa and 0.862 MPa respectively. Meanwhile, the thermal conductivity was 0.076 W/(m.K) and the water absorption could achieve 1.5%. It is concluded that adding walnut shell has no effect on the crystallization of the sample, but the walnut shell couldreplace a part of raw materials, resulting in the increase of density and strength. At the same time, the appearance of miscellaneous stomata could be attributed to the addition of walnut shell, and the number of open pores increased, leading to the increase of water absorption and thermal conductivity.

Abstract :
The mechanism of the surface depression of the foam glass was studied. A method of powder sintering with plate glass as the raw material and carbon black as the foaming agent was adopted to investigate the influences of foaming temperature, soaking time, moisture content in the release agent, and flame preheating temperature on the surface depression of a foam glass blank. The results indicated that insufficient cooling rate and rapid foaming process that could not react synergistically with the surface tension and viscosity of the glass melt aroused the mismatching between the glass melt and the expansion or contraction of gas, resulting in upper surface depression of foam glass. Besides, the batch carbon black at high temperature reacted with residual water in advance to generate large amounts of gas and form the air space which could expand inside, leading to lower surface depression of foam glass.

Abstract :
This work aimed to analyze the glass material used for sealing the end of a thermal collector in a parabolic trough solar power plant. Based on matched sealing requirements and application performance of glass and Kovar alloy 4J29, one borosilicate glass material (GD480S), whose expansion coefficient was similar to that of Kovar alloy 4J29, was studied. Moreover, the effect of the ratio of SiO2 to B2O3 on the glass properties was explored in detail by Fourier transform infrared spectroscopy. As the SiO2 to B2O3 ratio in the glass increased from 4.18 to 5.77, the expansion coefficient showed a decreasing trend from 4.95x10(-6)/ degrees C to 4.55x10(-6)/ degrees C In addition, the water resistance performance improved, enabling the glass material to seal well with the alloy for application in a trough solar power plant. Thus, the increase in the SiO2 to B2O3 ratio made the glass structure more compact and improved the glass performance to meet the requirements of an industrial tubular receiver.

Abstract :
In the paper, regarded SiO2-Al2O3-B2O3-RO system as basic composition, high-temperature glass glaze was prepared successfully by using Bi2O3 in place of Al2O3, and traditional melt annealing method was adopted. The influence of Bi2O3 on expansion coefficient, sintering temperature, electrical resistivity was investigated by DIL-2008, SJY sintering imager, Keythley2410. The results show that the sintering temperature of glass glaze has a wide range, which can reach 270 degrees C, so it is easy to sinter; with the increasing of bismuth oxide content, expansion coefficient of glass glaze gradually increases, whereas sintering temperature and electrical resistivity continuously decreases.
