Researchers report high performance solid-state sodium-ion battery

Organic cathode offers more reliable contact with electrolyte, a key to stability

24-Apr-2019

Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers reported developing an organic cathode that dramatically improves both stability ...

A smartphone system to test for lead in water

Can detect levels below EPA standards

28-Sep-2018

The discovery of lead in Flint, Michigan's drinking water drew renewed attention to the health risks posed by the metal. Now researchers at the University of Houston have created an inexpensive system using a smartphone and a lens made with an inkjet printer that can detect lead in tap water at ...

'Soft' robots that can move on their own

23-Apr-2018

If Star Wars' R2-D2 is your idea of a robot, think again. Researchers led by a University of Houston engineer have reported a new class of soft robot, composed of ultrathin sensing, actuating electronics and temperature-sensitive artificial muscle that can adapt to the environment and crawl, ...

Nanomaterials hold promise for producing hydrogen from water

23-Mar-2018

Hydrogen holds promise as an inexpensive form of clean energy, but finding an efficient and affordable way to produce the fuel from water - a technique known as water-splitting - remains a key scientific challenge. A researcher from the University of Houston is working with a colleague in Taiwan ...

Scientific advances can make it easier to recycle plastics

21-Nov-2017

Most of the 150 million tons of plastics produced around the world every year end up in landfills, the oceans and elsewhere. Less than 9 percent of plastics are recycled in the United States, rising to about 30 percent in Europe. That's a $176 billion problem, the potential energy savings ...

Inexpensive organic material gives safe batteries a longer life

21-Jun-2017

Modern batteries power everything from cars to cell phones, but they are far from perfect - they catch fire, they perform poorly in cold weather and they have relatively short lifecycles, among other issues. Now researchers from the University of Houston have described a new class of material ...

Searching for answers on the sea floor

How abiotic organic molecules are formed

14-Jun-2017

The sea floor may look barren, but Qi Fu, an experimental geochemist at the University of Houston, says there are places where it is teeming with life. Hydrothermal vents, fissures on the sea bottom which release fluids heated by volcanic rocks, are particularly rich, but science can't yet ...
