Hexabromocyclododecane containing polystyrene foam obtained from the building and construction market has been co-incinerated in a full-scale waste incineration plant. The co-feeding of 1 and 2 wt% of polystyrene foam had no influence on the operation of the plant. The bromine content increased the raw gas hydrogen bromide concentration slightly. The air emission, including that of dioxins and ...

Laser-polarized Xe dissolved in a foam preparation of fresh in blood found 4.5 { 1 s in red blood cells and 9 { 2 s in human blood was investigated. The NMR signal of Xe dissolved plasma (18) . This experiment used thermally polarized Xe in blood was enhanced by creating a foam in which the dissolved and therefore required many hours of signal averaging. PoXe exchanged with a large reservoir of...

In this work, we for the first time have proposed and fabricated a self-propelled Janus foam motor for on-the-fly oil absorption on water by simply loading camphor/stearic acid (SA) mixture as fuels into one end of the SA-modified polyvinyl alcohol (PVA) foam. The as-fabricated Janus foam motors show an efficient Marangoni effect-based self-propulsion on water for a long lifetime due to the eff...

Life cycle assessment is applied to assess the environmental benefits and trade-offs of a solar-assisted heating, ventilating, and air-conditioning (HVAC) system installed in the CIESOL building in Almeria (southeastern Spain). The environmental performance of this system is compared to that of a conventional HVAC system using a heat pump. The study evaluates these systems from cradle to grave,...

Liquid foams were recognized early to be porous materials, as liquid flowed between the gas bubbles. Drainage theories have been established, and foam permeability has been modeled from the microscopic description of the equivalent pores geometry, emphasizing similarities with their solid counterparts. But to what extent can the theoretical work devoted to the permeability of solid porous mater...

Since it is low in cost and toxicity has good biodegradability, gas-liquid-foam three-phase flow been widely used industrial fire protection. Due to the different characteristics of gas, liquid, foam, liquid precipitation liable occur under static conditions, resulting unstable performance mixture. To improve extinguishing efficiency, great significance study separation process gas-liquid-foam....

This review focuses on the role of proteins in the production and maintenance of foam in both sparkling wines and beer. The quality of the foam in beer but especially in sparkling wines depends, among other factors, on the presence of mannoproteins released from the yeast cell walls during autolysis. These proteins are hydrophobic, highly glycosylated, and their molecular masses range from 10 t...

In this research effect of synthesis method of magnesium aluminate as support of Ni catalysts at the reverse water gas shift (RWGS) reaction was evaluated. The RWGS reaction is applied in Carbon Dioxide Hydrogenation to Form Methanol via a Reverse Water-Gas Shift Reaction (CAMERE) process for the transformation of CO2 into methanol. The MgAl2O4 supports were prepared by sol-gel (M1), surfactant...

Middle distillate (MD) transportation fuels, including diesel and jet fuel, make up almost 30% of liquid fuel consumption in the United States. Alternative drop-in MD and biodiesel could potentially reduce dependence on crude oil and the greenhouse gas intensity of transportation. However, the water and land resource requirements of these novel fuel production technologies must be better unders...
