Apr 13, 2023 (Nanowerk News) The location of the brightest cosmic explosion ever recorded was pinpointed at 2.4 billion light years from Earth by a team of astronomers. The blast, known as a gamma-ray burst (GRB), was first picked up by sensors on veteran spacecraft Voyager 1 last October, only...
Gentle method allows for eco-friendly recycling of solar cells
Apr 13, 2023 (Nanowerk News) Today there are two mainstream types of solar cells. The most common is silicon-based and accounts for 90 percent of the market. The other type is called thin-film solar cells which in turn uses three main sub-technologies, one of which is known as CIGS (Copper...
Hybrid laser pulses enable ultrafast control of spin and valley currents
Apr 13, 2023 (Nanowerk News) The flow of matter, from large-scale water currents to the microscopic flow of electric charge, is fundamental to the infrastructure of modern society. Scientists are constantly seeking ways to control quantum aspects of matter, such as electron spin and valley states, in order to make...
Implantable device shrinks pancreatic tumors
Apr 13, 2023 (Nanowerk News) Houston Methodist nanomedicine researchers have found a way to tame pancreatic cancer - one of the most aggressive and difficult to treat cancers - by delivering immunotherapy directly into the tumor with a device that is smaller than a grain of rice. In a paper...
