“…Common glass has high temperature resistance and a maximum glass transition temperature which is more than 1000 °C. So, vacuum glass formed by a vacuum and two common glasses has better thermal insulation performance and high temperature resistance [18,19]. If vacuum glass and neutron shielding glass were combined to a new multiple glass, this glass will have the advantage of neutron shielding, optical properties, thermal insulation performance, and high temperature resistance.…”

The neutron shielding glass is widely used in nuclear/fusion plants. To improve its temperature resistance and heat insulation, a Gadolinium (Gd)-containing laminate vacuum multiple glass is proposed by using the vacuum insulation method. A 3D finite element model validated by theoretical calculation was developed to analyse the heat transfer path and numerical simulation of the multiple glass was carried out to obtain the temperature distribution and the maximum temperatures of the organic glass in relation to dynamic working temperatures, the sealing agent width, view size, and vacuum thermal conductivity. The results show that the vacuum layer between common glasses can make the work temperature of neutron shielding glass increase. The multiple glass has good heat-shielding performance and it is expected to work in a high-temperature environment. In addition, the vacuum layer between the common glasses and the sealing agent width decay with respect to the view size and vacuum thermal conductivity show an increase in the working temperature of the neutron shielding glass. It was concluded that the order of affecting the temperatures of the organic glass follows the pattern of: view size > vacuum thermal conductivity > sealing agent width.

“…A selective wavelength based single junction transparent photovoltaic film has a theoretical Shockley-Queasier (SQ) limit of 20.6% [63] conversion efficiency at 100% average visible light transmittance and the conversion efficiency can be increased by adding junctions. However, glass sheet alone has about 92% average visible light transmittance [64,65], and a typical double air-filled [66,67,68] or vacuum glazing [69,70] has approximately between 70 % and 80% average visible light transmittance [71] and it would drop to 70% with the application of a low emissivity (low-e) coating to further reduce the radiative heat transmission. However, the low-e coatings can be avoided or replaced with transparent PV film as the initial research suggests it would not make a huge impact on the thermal transmittance values [72,73,74] since vacuum insulation would be an advantage irrespectively.…”

This study bestows an essential abridged review of the manifestations of carbon capture & storage (CCS) systems and the ambivalence of quantum-dot & organic photovoltaic (PV) solar cells. This research implicates that CCS system is evolving in capturing CO 2 emissions from coal-fired electrical power stations to further mitigate climate change. Different manifestations are discussed for capturing and storing the CO 2 with repercussions on operating costs, toxicity and energy efficiency. Chemical Looping Combustion appears to be the more energy efficient than Oxy-fuel CFBC and Ionic Liquids, and less expensive than Calcium Looping and Amine Scrubbing. Calcium Looping (Cal) and Ionic Liquids are also less toxic than Amine Scrubbing. Direct air technology is also very compelling at capturing CO 2 emissions but highly expensive. Nevertheless, further research is still required for all CCS systems to be able to implement them widely in existing/new electrical power stations. Waste heat energy recovery systems can be used in conjunction with CO 2 capture systems for further reduction of emissions. The ambivalence of quantum dot and organic solar cells are briefly reviewed. It implicates that composite film with enhanced quantum dot effects will make the film highly transparent and options of tunability of its color spectrum make the quantum dot solar cells highly attractive to a wide variety of applications. Organic solar cells are carbon-rich polymers and can be designed to improve a precise function of the cell, such as sensitivity to a certain type of light. OPV cells can only be considered as half-competent to crystalline silicon and have smaller beneficial lifespans, but could be less costly to produce in high volumes. Current research issues are substitution/compromises between electrical power conversion efficiency and average visible light transmittance. However, improving average light-transmittance decreases electrical power conversion efficiency and vice versa.

“…Vacuum plate glass, as a new type of transparent energy-saving advanced insulation technology currently emerging in the world, has excellent insulation, anti-aging, and infrared reflection properties. It has wider scope in the net-zero energy buildings due to its lower U-value of less than 1 Wm −2 K −1 [1,2] for vacuum-separated glass sheets and 0.33 Wm −2 K −1 for dual-vacuum-separated three glass sheets [3,4]. It is a research hotspot in glass processing technology in China and worldwide.…”

Laser sealing for vacuum plate glass is a key step in developing the cost-effective smart vacuum-glass window for the drive towards net-zero energy buildings. In this paper, the pores, cracks, and interface with laser welding are analyzed in depth using PbO-TiO2-SiO2-RxOy system sealing solder to prepare vacuum flat glass. The microstructure of the sealing layer was analyzed by a BX41M-LED metallographic microscope, and the interfacial bonding characteristics were observed by thermal field emission scanning electron microscopy (SEM). The solder was analyzed by an energy spectrometer, and the influence of laser power, sealing temperature, and sealing speed on the gas holes and the crack sand interface separation of the sealing layer are reported. The results show that when the laser power reached 80 W at the welding speed of 2 mm/s, the bulk solder disappeared to most of the quantity and the sealing surface density was higher, due to which negligible pores and micro cracks were found. Thus, the sealing quality of the sealing layer is considered to be suitable when the temperature of 470 °C was maintained and the solder has 68.93% of Pb and 3.04% Si in the atom fraction to achieve the wet the glass substrate surface whilst improving the bonding quality.
