Colorless non-marking coffee

18.04.2017

Slovak scientists have developed a composition of a unique coffee drink that is colorless and does not leave marks on tooth enamel and clothing. At the same time, the qualities of coffee loved by many were left untouched.

The drink does not leave marks on tooth enamel and clothes. A new type of coffee is completely ready to drink, it does not need to add cream or sugar.

Brothers-scientists David and Adam Nady took up such work after they were tired of struggling with coffee plaque on their teeth. The reason for the dark shade of the tooth enamel was the residue of resin and oil found in coffee. The Slovak experts dubbed their drink Clear Coffee.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Wireless charging for Toyota electric vehicles 11.12.2013

Toyota Motor Corporation has entered into an agreement with WiTricity Corporation, a manufacturer of induction chargers. The peculiarity of WiTricity's business model is that it does not sell finished products, but licenses for their development. Through the collaboration, Toyota will gain access to WiTricity Corporation technologies. The ultimate goal is to equip both all-electric and hybrid Toyota vehicles with wireless battery charging systems.

Chargers based on WiTricity patents use the classic effect of electromagnetic induction, which involves the interaction of two coils with current. In this case, one of the coils is built into the transmitter connected to the electrical network (it can lie, for example, on the garage floor), and the second coil is located inside the car. The battery starts charging automatically when the car is parked over the transmitter.

With regard to passenger cars, the technology allows charging an "empty" battery in 4 hours, while transferring from 3,3 to 6 kW of energy. This figure can reach 25 kW for larger vehicles. The developers report that wireless charging takes about the same time as conventional charging from the mains.

To date, it has not been specified in which Toyota car models WiTricity technology will be used. In August 2013, the Japanese automaker announced plans to add wireless charging capabilities to its green Prius line. At that time, it was about the 2014 Toyota Prius Plug-In model.

There are more than 2445 CHAdeMO express charging stations globally today, roughly double the number from a year earlier, according to analysts at IHS Automotive. CHAdeMO technology is supported by more than 57 electric vehicles (including Mitsubishi i-MiEv, Nissan Leaf and Honda Fit EV models), accounting for about 80% of the non-ICE vehicle market.

The cost of installing one CHAdeMO charging station is in the range of 20-30 thousand dollars. Such a station makes it possible to charge the batteries in about 20 minutes, although, of course, this is still much longer when compared with the time of refueling gasoline at a conventional gas station.

Tesla Motors is working on a faster "recharge" method. The company equips its vehicles with rechargeable batteries that can be replaced after being discharged at specialized stations. This battery replacement takes only 10 minutes.
