Recently, the National Development and Reform Commission jointly issued with the National Energy Board, “on the promotion of biomass heat for the development of guidance”, “opinions” clearly the biomass heat as an important measure to deal with air pollution and accelerate the biomass heat in the region Civil heating and small and medium-sized industrial park heating in the application of building a distributed green low-carbon clean and environmentally friendly heating system.

In accordance with the planning goal, by 2020, China‘s biomass cogeneration capacity will exceed 12 million kilowatts, the annual utilization of biomass molding fuel about 30 million tons, biomass gas annual utilization of about 10 billion cubic meters of biomass for Heat total direct replacement of about 30 million tons of coal.

It is reported that as a green low-carbon clean and renewable energy heating economy, biomass heating mainly through biomass cogeneration and biomass boiler heating in two forms, directly on the user side to replace fossil fuels, and at Replacing county and rural coal-fired heating has a huge effect.

Compared with the traditional methods of communication, quantum communication with high security as the future direction of communications development, often reported quantum communications are based on the principle of entanglement, today to introduce a more weird form – Anti-Fictitious Communication: There is no quantum communication between two recipients for the quantum communication. The effect of not sending the quantum state of the particle transmission is also called the quantum Zeno effect.

According to a recent report by the Physiotherapist Organization Network, researchers at China University of Technology successfully implemented direct counter-factual quantum communication, transmitting a black-and-white bitmap from one location to another without sending any physical particles, For the first time. The research was designed and experimented by the cooperation between China University of Science and Technology Shanghai Branch and Hefei Branch and Tsinghua University Chinese scientists, and successfully implemented counterfactual communication with a nested quantum Zeno effect.

Quantum Zeno effect occurs in unstable quantum systems that are repeatedly measured. In the quantum world, observing or measuring systems can cause changes in the system. In this case, unstable particles will never decay when observed repeatedly. The quantum Zeno effect creates a virtually frozen system with a high probability. The study was published in the Proceedings of the National Academy of Sciences.

Science and Technology Daily, Beijing, November 23 (Reporter Zhang Jiaxin) Under the guidance of machine learning, researchers at the Oak Ridge National Laboratory in the United States have designed a record-breaking carbon-based supercapacitor material that stores four times the energy of the current best commercial material. Supercapacitors made with this new material can store more energy, thereby improving regenerative braking systems, power electronic devices and auxiliary power supplies. The relevant paper was published in the latest issue of Nature Communications.

The researchers said that they have created a carbon material with enhanced physicochemical and electrochemical properties, pushing the energy storage boundaries of carbon-based supercapacitors to a new level. This is the highest storage capacity of porous carbon ever recorded and is a “real milestone.”

Commercial supercapacitors have two electrodes, an anode and a cathode, which are separated and immersed in an electrolyte. At the interface between the electrolyte and the carbon, the double layer reversibly separates the charge. The preferred material for making supercapacitor electrodes is porous carbon. These pores provide a large surface area for storing electrostatic charges.
