Various molecular systems have been developed by researchers for photoinduced (i.e., light-driven) electron transfer, including supramolecules, hybrid materials, and organic polymeric systems. While these systems fulfill the distance criterion required by

Oceans cover most of Earth's surface and support a staggering number of lifeforms, but they're also home to a dilute population of uranium ions. And -- if we can get these particular ions out of the water -- they could be a sustainable fuel source to ge

A verdant forest is one of the most iconic symbols of the power of nature, from the abundance of plant and animal life that shelters among its thick vegetation to the positive impact it has on Earth's climate, thanks in part to photosynthesis, which remo

The transition to a society without fossil fuels means that the need for batteries is increasing at a rapid pace. At the same time, the increase will mean a shortage of the metals lithium and cobalt, which are key components in the most common battery typ

Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it

For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of

A new study by researchers at the University of Illinois Urbana-Champaign advances fundamental knowledge about the role of solvation in ion binding and presents a new pathway for electrochemically controlling ion selectivity. The study was published in 阅读全文

About half of an average American building's energy consumption is spent on heating and cooling. That's a lot of money spent, fossil fuel burned and strain on an aging energy infrastructure during times of severe temperatures.

While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching t

Researchers at North Carolina State University have now identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning, such as Styrofoam™. Rather than dis

Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the disruptive wavelength
