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 ... >>

Miniature 30W Charger 21.04.2021

Since the introduction of gallium nitride in chargers, there have been many pocket-sized adapters up to 120W on the market. Presented on the charger AOHi Magcube 30W is the smallest adapter of this power.

This charger weighs 42 grams and measures 28 x 28 x 32mm. According to the manufacturer, this charger is approximately equal to a 5-watt Apple power supply.

The AOHi Magcube 30W features a USB-C connector and also has a built-in LED indicator that glows amber when your device is fast charging, turns blue when it's charging at standard speed, and turns green when it's charging continuously.

This adapter allows you to charge your iPhone 12 at 20W and also supports various charging protocols such as Power Delivery 2.0 and 3.0, PPS, Apple 2.4, BC 1.2 and Quick Charge 2.0, 3.0. and 4.0+. The adapter is compatible with Nintendo Switch and even has a charging mode for small devices such as headphones, smartwatches and fitness trackers.
