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 ... >>

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 ... >>

Vegetable casein for dairy-free cottage cheese 11.06.2024

In today's world, there is a growing demand for environmentally friendly and ethically produced products. One startup, NewMoo, Ltd., is offering an innovative solution in this area by using plant molecular farming (PMF) to produce casein proteins needed to make cheese. These proteins make it possible to produce cheese that is as good as traditional dairy cheese, without the use of animals and with minimal environmental impact.

Scientists at NewMoo have developed a method for expressing casein proteins in plant seeds that can be grown using conventional agriculture. After three years of research and experimentation, the company introduced proteins that match the nutritional properties, composition and functions of milk proteins. This technology is based on research conducted at the Weizmann Institute of Science in Rehovot, Israel, and allows the expression of two or more caseins in a single plant.

Seeds of plants that express casein proteins are sown in open fields. After harvesting, liquid casein is produced, free of hormones, lactose and cholesterol, which has all the functional characteristics of milk casein. Daphne Miller, co-founder and CEO of NewMoo, explains: “Our animal-free liquid casein mimics all the functional characteristics of the real milk protein used to make cheese the traditional way.”

Using NewMoo caseins allows cheesemakers to produce high-quality cheese without the need to change equipment or technology. Vegetable casein provides the same properties as milk casein - it melts, stretches, and has a characteristic aroma, taste and texture that cheese lovers appreciate. Thus, plant casein becomes a complete alternative to dairy, suitable for use in a wide range of cheese products.

The process of producing plant casein is not only economical, but also environmentally sustainable. Freeing cows from industrial milk production reduces greenhouse gas emissions and reduces the carbon footprint associated with animal agriculture. Using plant sources to produce casein also contributes to sustainable agriculture by helping to sequester carbon and support biodiversity.

NewMoo's development of plant-based casein opens up new possibilities for producing dairy-free cheeses while maintaining the taste and texture of traditional dairy products. This innovative approach promotes the creation of environmentally friendly and ethically acceptable products, meeting the growing demand for such products. Bringing this technology into production could be a significant step towards a more sustainable and ethical future for the food industry.
