New transistor could cut 5% from world’s digital energy budget

A new spin on one of the 20th century’s smallest but grandest inventions, the transistor, could help feed the world’s ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet.A new spin on one of the 20th century’s smallest but grandest inventions, the transistor, could help feed the world’s ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet.

Converting solar energy to electricity on demand

The researchers behind an energy system that makes it possible to capture solar energy, store it for up to 18 years and release it when and where it is needed have now taken the system a step further. After previously demonstrating how the energy can be extracted as heat, they have now succeeded in getting the system to produce electricity, by connecting it to a thermoelectric generator. Eventually, the research—developed at Chalmers University of Technology, Sweden—could lead to self-charging electronics using stored solar energy on demand.The researchers behind an energy system that makes it possible to capture solar energy, store it for up to 18 years and release it when and where it is needed have now taken the system a step further.

Organic semiconductor-based nanoparticles with long-lasting reactive charges

Due to their advantageous properties, organic semiconductors could be very promising photocatalysts for producing solar fuels. In fact, these materials can be synthetically tuned to absorb visible light, while simultaneously retaining energy levels that are desirable for driving various processes. While photocatalysts based on organic semiconductors have attained promising results, the understanding of the physics underpinning their functioning is still relatively limited.Due to their advantageous properties, organic semiconductors could be very promising photocatalysts for producing solar fuels.

Solar nanowire-nanotube filter offers easy access to clean drinking water

Even today, clean water is a privilege for many people around the world. According to the World Health Organization (WHO), at least 1.8 billion people consume water contaminated with feces, and by 2040, a large portion of the world will endure water stress because of insufficient resources of drinking water. Meanwhile, according to the United Nations Children’s Fund (UNICEF), around 1,800 children die every day from diarrhea because of unsafe water supply, which causes diseases like cholera.Even today, clean water is a privilege for many people around the world.
