Under what conditions did Spielberg agree to receive an honorary degree from the School of Cinematography?

Steven Spielberg applied three times to the USC School of Cinematography and was rejected three times due to low grades. Years later, when Spielberg became a famous director, the school wanted to give him an honorary degree. He agreed on the condition that the signature of the person who signed those same refusals would be on the diploma. Spielberg also makes annual cash donations to the school.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Special electrodes for battery operation in cold weather 26.06.2022

It is known that temperatures below the freezing point of water have a very detrimental effect on the basic parameters of lithium-ion batteries. In the context of electric cars and other vehicles, this means shorter travel distances, longer charging times, problems with regenerative braking systems, and more. Therefore, engineers and scientists involved in the development of new batteries pay great attention not only to increasing their capacity, but also to ensuring uninterrupted operation in extreme temperatures.

Some automakers, notably Ford, equip their car batteries with temperature sensors and heaters that keep the battery temperature within acceptable limits. At the same time, part of the battery energy is spent on heating them, which reduces the travel range of an electric car. Other battery manufacturers use special electrolytes that can operate at sub-zero temperatures.

In the same area, there is a group that includes scientists from several Chinese scientific institutions. They conducted research, the results of which showed that one of the vulnerable components of the battery, responsible for the loss of capacity when the temperature drops, is the anode, one of the battery's two electrodes. As a rule, anodes are made of graphite, which has a flat, smooth surface. So Chinese scientists started experimenting with various alternatives and eventually came across a very promising solution.

The scientists took the composite material ZIF-67 (cobalt-containing zeolite imidazolate framework) and heated it to a high temperature, resulting in the formation of 12-sided carbon nanospheres. These tiny structures have a very developed surface, in addition, they have excellent electrical conductivity. By pressing the resulting material, the researchers made a coin-shaped anode for a battery with a lithium metal cathode.

The conducted experiments showed that the created battery provides stable characteristics during charging and discharging in the temperature range from 25 to -20 degrees Celsius. At temperatures below zero, the battery capacity still drops, but only slightly, to 85,9 percent of its original capacity, which is not comparable to that of traditional lithium-ion batteries. And even at a temperature of -35 degrees Celsius, the battery with the new anode was able to take charge and almost completely give it away during the discharge process.

Scientists believe that the implementation of the results of their work can significantly expand the functionality of lithium-ion batteries in extreme environmental conditions. And not only electric cars, but also drones for various purposes, spacecraft and much more can benefit from this.
