<p style="text-align:justify"><em>Supercapacitors have the superb ability to capture and store energy. Researchers can use different materials and fabrication methods to make them flexible, thin and appropriate for use in wearable or implantable electronics, like smart watches or pacemakers, but those approaches tend to be intricate and costly. Now, however, a team from Jilin University in China has developed a new type of all-in-one adhesive electrode that solves one of the major issues facing advancing flexible 2D supercapacitors &mdash; making the components work s...

<p style="text-align:justify"><em>Current lithium-ion battery technology does not have the energy density necessary to meet the demands for renewable energy. In theory, lithium-sulfur batteries could be a viable alternative with a higher specific capacity and energy density. However, sulfur has disadvantages that currently limit its practical adoption. </em></p>

<p style="text-align:justify"><em>Zinc-air batteries are an inexpensive, powerful battery alternative that can be used on the small scale to power electronics or on the large scale for electric vehicles or energy storage. These batteries work when oxygen from the air oxidizes zinc, but the difficulty in oxygen activation, which degrades battery performance, has prevented their wide commercial adoption.</em></p>

<p style="text-align:justify"><em>In recent years, carbon-based catalysts &mdash; especially nitrogen-doped nanocarbons &mdash; have emerged as sustainable, reliable alternatives to the metal catalysts that have traditionally been used to support chemical reactions. Researchers from Fuzhou University synthesized nanocarbons from guanine molecules to better understand the precise role nitrogen plays in the carbon-based materials and explore the reaction mechanisms of these catalytic systems.</em></p>

<p style="text-align:justify"><em>A researcher from the New Jersey Institute of Technology has published a perspective paper that examines sentience and its application to artificial intelligence (AI) and robotics. Sentience describes the ability to sense and feel, drawing its meaning from the Latin word </em>sentire<em> which means &ldquo;to feel.&rdquo; The paper addresses a set of ideological commitments at stake in debates over sentient machines. The author proposes that artificial sentience is both necessary and impossible.</em></p>
