Not long ago, the first case of illegal dumping of landfill leachate and caused environmental pollution of Yunnan which has caused much concern has been adjudged; the defendant because of surrender and pleaded guilty with a good attitude, has jailed for 2 years and will respite for 2 years, also he was imposed a fine of 20,000 and do some service as a environment volunteer. It is reported that this case is because the defendant privately dumped his transportation of 29 cars which totaled 568.34 tons of pollutants into the environment, under the case of known the heavy metals, organic compounds should be transported to a special institution for professional treatment, and thus caused serious pollution to the surrounding environment. In this regard, the court verdict this case based on the principle of "spoiler repairs, polluter controls".   Landfill leachate is the high concentration of organic or inorganic ingredients liquid which generates from the landfill garbage pi...

Recently, the Chinese Academy of Physical and Chemical Research Institute has successfully synthesized a highly efficient water electrolyzing catalyst to achieve high efficiency at a low voltage of activating water molecules, and offered the potential for solving the future energy crisis. Hydrogen is considered as the best source of energy, unlike the other new energy sources, like solar, nuclear, ocean, biomass and geothermal energy and so on, it belongs to the energy of energetic body which is available direct combustion. Among the hydrogen production technologies, the way of solar water photolysis or photo-assisted electrolysis of water is one of the most promising and efficient pathway, which is depending on the semiconductor electrode, and moreover, the water electrolyzing catalyst can greatly improve the efficiency of water electrolysis hydrogen. Zhang Rui, one of the researchers led his team carried out a in-depth study on the nanostructure of "Hydrotalcite (LDH)...

In June, a primary school of Huayuan County of Hunan Province, China, occurred a serious mercury poisoning (Minamata disease) of many students, which resulted in 147 students urine mercury exceeded; its cause is a fifth-grade student took 50 ml of the remaining mercury in the wok of a waste workshop in a mineral water bottle to school, and gave it to the other students for playing. According to the source, this workshop was illegal constructed and operated unauthorized without Environmental Impact Assessment (EIA) and related procedures. For this accident, I am showing my deep sadness, someone innocent was suffered a serious injury because some unscrupulous manufacturers do not manage their hazardous substances.   China as the largest country which uses and emissions most  in global mercury, and has faced with the tremendous pressure to reduce emissions of mercury reductions in the "global mercury instrument" negotiations. This year, on June 18th to 19th, "the sec...

Virtual Reality (VR) and Augmented Reality (AR) are now leading the forefront of technology, what the surprises will be by the further combination of AR and VR? Recently, source pointed out that Halo holographic helmet has opened the official website pre-sale, and will deliver to the customers after the International Consumer Electronics Show in January 2017. It is reported that this holographic helmet can switch in a key between AR and VR, using the most advanced processor, and based on a whole new generation customization system, can achieve low latency display in the sensor; at the same time, it supports gesture recognition, without any external testing equipment to achieve SLAM, and supports real-time 3D modeling space. In addition, the key to switch between AR and VR of this holographic helmet in a key lies in the eyepiece glass with a special chemical materials sandwich, after conductive of the special sandwich of film, a reversible color change of light will occur, such as the ...

With the whole society to improve air quality concerns, China in recent years regarded environmental protection as an important work and expanded, the emerging energy, chemical and other industries are required to must equipped with exhaust gas purification, waste water treatment equipment; also, the old coal enterprise are asked to carry out reforming and installing some equipments to the boiler, thus the ultra-low emissions has become the mainstream environmental topics.    Media recently reported that Power Plant of Tongliao, Inner Mongolia of China, has started a wide load denitrification renovation project on its No.5 Unit from late May this year and it has been completed with the ongoing production and other external insulation finishing work. According to the source, this transformation is due to the No.5 unit has the situations of lacking of steam and temperature under the high-load condition, denitration can not to be put into operation under the low-load. The ...

Recently, Nissan release the automobile solid oxide fuel cell (SOFC): vehicles which equipped with solid oxide fuel cells will use bio-ethanol rather than the liquid hydrogen. Produce ethanol reformer hydrogen combines with oxygen in the air in a fuel cell to produce electricity, then discharging water. According to the source, this system is more efficient than the existing hydrogen fuel cell system, which the recharge mileage can reach about 600 km. what kind of black tech is SOFC? SOFC is the third generation of the fuel cell, a solid-state chemical mean which direct converted efficiently and environmentally friendly the chemical energy which is stored in the fuel and oxidizer to electric energy at high temperature, a fuel cell which is considered to be widely applied as the proton exchange membrane fuel cell (PEMFC) in the future.   SOFC does not require expensive platinum as a catalyst with both the anode and cathode materials are oxides. WO 3  is a semiconductor-t...
