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 ... >>

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 ... >>

Pedestrians are safer with robot cars 13.05.2012

Engineers from the Massachusetts Institute of Technology have found a way to solve the problem of communication between robot cars and pedestrians.

At present, many problems of automated transport have been practically solved: robots have learned to avoid obstacles, move in traffic, navigate on a map, and pass each other at intersections. However, it is impossible to introduce automatic road transport until the main problem - the safety of pedestrians - is solved.

Imagine the situation: you are standing on a pedestrian crossing and you see how a robot car rolls up to it, slowing down. Is it possible to transfer? Will the car stop or vice versa - it will rush forward? If a person is driving, you can understand whether he sees a pedestrian or not - in extreme cases, you can exchange gestures. With a robot, it's more difficult.

A group of engineers at MIT have developed a simple device that lets others know what's on the mind of a robot car. The system is equipped with several types of alarms. For example, when a car notices you, bright LED lights start flashing in different colors - from orange to red (depending on the distance). If the car does not see the pedestrian, then the lights are blue. Also, the robot-driver using the speakers can offer the pedestrian to cross the road or vice versa to stop. Thus, the robot can tell the pedestrian about his "plans" even more than a live driver.
