The Chinese company announced the creation of a car that can travel 500 km on water

The Chinese company Qingnian Cars presented a prototype of a vehicle that can travel from 300 to 500 km only on water.

During a demonstration of the car, Qingnian Cars CEO Peng Kyangnian explained that the engine runs on hydrogen, which is formed by a chemical reaction when a catalyst reacts with a mixture of aluminum powder and water. According to the description, the prototype can travel up to 500 km at 300-400 liters of H2O.

The automaker plans to recycle the reagents used in the process.

Peng Kyangnyan added that the cost of operating the transport and the production of new engines will not be high, but did not name the exact amount, citing trade secrets. Long-range test data are also not released..

Qingnian Cars has been developing a new technology together with scientists from Hubei University of Technology since 2006..  According to them, transport will be able to use ordinary water, which does not need to be exported, and by-products from the operation of the car do not pollute the environment..

Despite no open demonstration of the prototype, engineers have not yet talked about mass production, and some Chinese have called the development inconclusive due to the lack of evidence of successful long-distance travel..

Major car manufacturers are also gradually moving towards green technologies. By 2039, Mercedes-Benz plans to end sales of vehicles with a traditional combustion engine and fully switch to zero-emission models.

Russian physicists have developed a new way to cool a quantum computer

A group of scientists described the technology of remote control of the entropy of specific qubits, which actually locally violates the second law of thermodynamics in the system. The device can be applied to point cooling of quantum computers, to create nanocoolers or heaters.

One of the basic laws of physics states that disorder of an energetically isolated system cannot spontaneously decrease. However, researchers from the Moscow Institute of Physics and Technology with colleagues from the United States and Switzerland have presented a device that allows you to manipulate this state, changing it on demand. To be precise, they described the spatially-separated quantum demon Maxwell, acting at a distance of up to 5 meters.

As a qubit, the scientists used a tiny superconducting device made up of thin layers of aluminum on a silicon chip. The system is called an artificial atom because, under ultra-low temperature conditions, it behaves like an elementary particle with two energy levels. Once connected, the qubits begin to exchange virtual photons, which leads to a change in their state.

The second device (demon), brought to a clean state, transfers it to the first, and itself becomes «dirty». In this case, the working qubit decreases its entropy, while maintaining the same energy. Essentially the second device «eats» disorder.

An example is billiard balls, which, after being hit with a cue, fly in all directions. The described technology makes all the balls return to their original state, in fact, turning back the clock..

Since qubits are in a pure state for only a fraction of a second, manipulations can be performed many times. In practice, this can be used to develop algorithmic cooling of a quantum computer, a subroutine that can purposefully cool individual qubits, reducing the amount of noise and errors..

You can also create a microscopic refrigerator that affects not the entire volume, but specific points. Since the process can be started in the opposite direction, not only cooling is possible, but also heating..

When working with two qubits, the effect was achieved in 85% of cases, and with the addition of the third, the effect was only 50%. However, scientists plan to reduce the error rate by improving the equipment used..

Scientists erased memories from rats with CRISPR genome editing

Genome Editing with CRISPR-Cas9

Neuroscientists have developed technology to remove pathological memories for the treatment of PTSD, drug addiction and certain chronic diseases.

Negative emotions, such as fear, are necessary for our survival, but when a person cannot cope with them and forget, then this can cause various disturbances. Treating pathological memories can relieve conditions such as PTSD, chronic pain and stress, and drug addiction.

Researchers at Peking University have developed a new system for modifying the genome in various types of cells, including neurons in the brain. They reported the successful use of this CRISPR-cas9-based technology to kill genes related to fear memory in laboratory rats..

Physicians around the world are currently experimenting with genome editing to treat chronic and congenital diseases. However, applying similar methods to people related to a number of ethical issues.

Invented durable eco-friendly foam that insulates better than traditional

Insulation – types, features, and flaws

Researchers have developed an environmentally friendly plant-based material that outperforms traditional foam in thermal and mechanical performance. It retains its properties under the influence of water and high temperature.

Expanded polystyrene (traditional styrofoam) is used in a variety of applications, from materials for construction and transportation to coffee cups and packaging. However, it depends on oil, contains toxic substances and pollutes the environment..

Working to create an effective alternative, a team at Washington State University developed a material that is 74% cellulose nanocrystals from wood pulp. Another 7.5% is accounted for by polyvinyl alcohol, which binds to nanocellulose crystals and increases the elasticity of the structure. The remaining 18.5% is occupied by the crosslinking agent.

The resulting composite foam has a homogeneous cellular structure, making it a good insulator. Its thermal conductivity is 0.027 W / (m ∙ K), which is superior to that of traditional expanded polystyrene. The new material is also very lightweight and can withstand the weight 200 times its own, without changing the shape. It decomposes well and does not form polluting ash when burned.

The team also developed a simple manufacturing process using water as a solvent and obtained cellulose nanocrystals by acid hydrolysis..

Next, scientists will work on increasing the strength and durability of the material, developing new compositions. They also plan to use inexpensive raw materials so that eco-friendly foam can be produced commercially..

Recall that earlier researchers have made thin polymer films that conduct heat better than many metals and ceramics..

Traffic Turbine: New device harnesses energy from busy roads

Wind turbines have been created to collect energy from moving vehicles

British company Alpha 311 has developed wind turbines for roadside lampposts that generate energy from air currents created by moving vehicles..

Every person who has ever been near the road felt the gusts of wind after any passing car. British businessman Barry Thompson decided to come up with a solution to harvest this wasted energy..

He created a cylindrical wind turbine with a height of 2 m, which is designed to be installed on lamp posts near highways. According to the engineer, each vertical device generates the same amount of energy as a 21 m2 solar panel. The company plans to make money by selling electricity to the state, some of which will go directly to road lighting.

The Alpha 311 development does not require any infrastructure changes as it is suitable for installation on existing poles and columns. The company is already in talks with local authorities to conduct tests on existing highways.

As a reminder, Peugeot previously developed a billboard that generates electricity from ambient noise..

Physicists began to synthesize superheavy elements of the eighth period of the periodic table

A team of Japanese nuclear physicists began experimenting with collisions between small and large atomic nuclei to synthesize new superheavy elements and discover new chemistry.

So far, scientists have managed to create all the elements in the first seven rows. – from hydrogen with one proton to oganesson, which has 118. Further research is hampered by the instability of superheavy elements due to the large number of protons. For example, the most stable isotope of nionium (113 protons) has a half-life of almost eight seconds, while for oganesson it is about 0.7 ms..

However, theorists believe that this figure may change for more massive nuclei, which will allow to obtain long-lived superheavy elements that will open up a new type of chemistry with longer reactions. To do this, scientists first need to know the repulsive force that the nuclei experience when approaching.

A team of researchers from Japan’s Institute for Physico-Chemical Research (RIKEN) said they have already begun experiments to collide small nuclei of neon, magnesium and calcium with larger atoms of curium and uranium, measuring how they scatter. Scientists estimate that the synthesis of one atom of a superactinoid will take more than three months..

 

Physicists began to synthesize superheavy elements of the eighth period of the periodic table

If the observed tendencies of the repulsive barrier and deformation are also valid for heavier nuclei, then the calculation of the optimal collision energy will take about a day. In the short term, the team plans to use this knowledge to create new elements. under the numbers 119 and 120. However, it will take at least a decade to discover stable isotopes of superheavy nuclei of the eighth period, since they will have unusual properties.

We also previously reported on the development of a new nuclear fusion method. using relativistic effects.
