Focus Description:

The magician ties the viewer's hands and asks them to try to tie the simplest knot on the cord. Hardly anyone can do it. After several unsuccessful attempts, you ask to have your hands tied and, after several manipulations, tie a knot.

Focus knot on cord

Focus secret:

To tie a knot on the cord, you need to do the following: form a loop on it, pass it from the inside under the ring tied to the hand, twist it once (i.e. 180 degrees) and drag it back over your hand, pass it from the outside under the ring and drag it over hand forward. In this case, an ordinary node is formed. The figure-eight knot will turn out in the same way, but the loop must be twisted twice (360 degrees).

Improving the efficiency of PbS quantum dot solar cells 14.06.2024

The latest solar technology research represents a significant breakthrough in improving the efficiency of PbS quantum dot solar cells. This method, based on the use of pulsed light, offers promise for simplifying the production and expanding the applications of these cells. A research team from the Daegu Gyeongbuk Institute of Science and Technology has developed an innovative method that uses pulsed light to improve the electrical conductivity of PbS solar cells. This method can significantly reduce the processing time required to achieve similar results. PbS quantum dot solar cells have significant potential in solar technology due to their photovoltaic properties. However, the formation of defects on their surface can reduce their performance. The new method helps suppress defect formation and improve electrical conductivity. Using strong light to complete the process ... >>

Magnetic Power Bank 5000mAh 14.06.2024

Huawei introduces a convenient and multifunctional charger to the market - Huawei SuperCharge All-in-One Magnetic Power Bank. This magnetic battery allows you to quickly and conveniently charge your Huawei phone anywhere, anytime. With a thickness of just 11,26 mm and a weight of 141 grams, this portable power bank fits easily into a pocket or bag, making it ideal for travel and everyday use. Despite its compact size, this battery provides enough power to charge your phone on the go. The new product supports wired charging with a power of 25 W and wireless charging up to 15 W (and up to 30 W when connected to an adapter), providing fast charging for both the power bank itself and other devices. The battery is compatible with various fast charging protocols such as SCP, UFCS and PD, making it ideal for a wide range of devices. The power bank is also compatible with Huawei phones that support wireless charging. ... >>

Changes in a father's brain after the birth of a child 13.06.2024

A recent study conducted by scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences found interesting changes in the brains of men after becoming fathers. These changes were associated with involvement in child care, sleep problems, and mental health symptoms. Scientists found that men who became fathers experienced a loss of brain volume after giving birth. This volume loss was associated with greater involvement in parenting, sleep problems, and mental health symptoms. Researchers have found significant changes in men's brains between the prenatal and postnatal periods. In particular, there was a loss of gray matter volume, especially in parts of the brain responsible for higher functions such as language, memory, problem solving and decision making. Men who paid more attention to their children and spent more time with them lost more gray matter in their brains. This also affected their mental health ... >>

Double carbon batteries 14.06.2014

The Japanese company Power Japan Plus has announced a breakthrough development in the field of rechargeable batteries. The development, called "Ryden", has double carbon contacts, and in terms of energy consumption it corresponds to lithium-ion batteries. At the same time, new batteries are superior to lithium-ion batteries in terms of safety and service life.

The technology, patented by Power Japan Plus, describes a battery design in which both the anode and cathode are made of carbon and an organic electrolyte is used. Positively charged lithium ions move towards the anode, negatively charged anions move towards the cathode, the electric current flow distance in the battery and the charging rate are higher than in common lithium-ion cells.

A new battery can withstand 3 charge and discharge cycles. The development is notable for its significant performance - the battery charges 20 times faster than lithium-ion batteries at a comparable energy density. Compared with other advanced battery technologies rated at 4V and above, the new battery is more powerful. The developers have also managed to achieve heat transfer losses, eliminating the risk associated with the risk of explosion and fire.

The production technology of the novelty is fully adapted to the existing production lines for conventional batteries and does not require significant changes to the equipment.

The new battery is free of rare earth, precious and heavy metals, which not only makes production, use and disposal extremely safe for the environment, but also greatly facilitates production logistics. In the production of such batteries, dependence on the political and economic situation in the world metal market is reduced. The company plans to switch to fully organic carbon in order to optimize its environmental impact, and in addition to receive 3 more patents for its development.

"The new generation of batteries delivers high performance but compromises on reliability, safety and cost. Our Rayden dual carbon design strikes a balance in all of these areas and outperforms existing batteries," said Power Japan Plus CTO Kaname Takeya.
