Approaching high-performance potassium-ion batteries via advanced design strategies and engineering

Potassium-ion batteries (PIBs) have attracted tremendous attention due to their low cost, fast ionic conductivity in electrolyte, and high operating voltage. Research on PIBs is still in its infancy, however, and achieving a general understanding of the drawbacks of each component and proposing research strategies for overcoming these problems are crucial for the exploration of suitable electrode materials/electrolytes and the establishment of electrode/cell assembly technologies for further development of PIBs. In this review, we summarize our current understanding in this field, classify and highlight the design strategies for addressing the key issues in the research on PIBs, and propose possible pathways for the future development of PIBs toward practical applications. The strategies and perspectives summarized in this review aim to provide practical guidance for an increasing number of researchers to explore next-generation and high-performance PIBs, and the methodology may also be applicable to developing other energy storage systems. Developing high-performance lithium-ion batteries (LIBs) is vital for regulating the energy output of intermittent solar and wind energy, wh...

High-Density Fiber Connections Solve Some Problems but Cause New Ones for Giant Data Centers

Three new types of connector options are gaining traction across the industry. All three connector styles also bring their own drawbacks as well as benefits. All connectors are inherently dirty because of the moving parts like springs, connectors, and latches, all of which generate wear debris; more connectors mean more debris. Specifiers will want inspection and cleaning products that will do the job right the first time. There will be no time, no people, and certainly no budget for do-overs. There is no doubt that our world is increasingly digitally interconnected. Today there are about 4 billion smart phones in use worldwide. High-speed 4G and 5G wireless networks make it possible to stream games, videos, and data-intensive apps like Roku and Waze to billions of mobile devices. Artificial intelligence apps like Alexa and “smart” home appliances are ubiquitous data hogs. New analytical tools such as high-frequency financial trading, credit card fraud detection, and even real-time aircraft tracking and maintenance only are possible due to the enormous predictive power of big data. Globally, we’re addicted to our data. Cisco estimates internet traffic will increase 127-fold from...

If you’ve worked with steel or iron, you will be very familiar with rust. You will have

If you’ve worked with steel or iron, you will be very familiar with rust. You will have an impressive armoury of wire brushes and chemicals to deal with it, and your sandblasting guy is probably in your speed-dial list. We’ve had more than one Hackaday reader contact us of late with videos showing an apparently miraculous handheld laser unit effortlessly stripping away rust, and leaving a near-perfect surface with little mess. Can it be real, they ask, is it an internet hoax? After all if you have done battle with the dreaded iron oxide you’ll know there is no miracle fix to the problem, however you deal with it there has traditionally been hard work involved. So after a bit of research, we find CleanLaser, the German company whose products feature in the videos. Quoting their website: “Powerful, very short, rapid and moving laser pulses produce micro-plasma bursts, shockwaves and thermal pressure resulting in sublimation and ejection of the target material”. So yes, it seems they’re real. The website is at pains to stress the environmental benefits of the devices over comparable sandblasting or similar technologies, but has very little information on their safety. They are avai...

With over 30 million foreign visitors each year, Paris is still the most popular tourist destination in the world. Hence it bears to reason that this is a city with a hotel to truly satisfy every traveler. The most sensational places to stay—both on the Right and Left Bank—include romantic palace hotels with world-class chefs, cozy vine-covered boltholes teeming with romance, and innovative design-forward converted townhouses. Rife with history, charm and vintage finds, accommodation is one thing this city of romance always gets right. First opened in 1898 by Swiss-born César Ritz, the Ritz Paris is a national treasure. Coco Chanel lived there for 34 years. And everyone from F. Scott Fitzgerald, Cole Porter, Rudolph Valentino, Winston Churchill, and Marcel Proust have rested their famous heads on the hotel’s silky sheets. Hemingway even got a bar named after him.

What’s the Difference Between Aluminum and Copper in Electrical Applications?

This site is operated by a business or businesses owned by Informa PLC and all copyright resides with them. Informa PLC’s registered office is 5 Howick Place, London SW1P 1WG. Registered in England and Wales. Number 8860726. There are obviously materials property differences, such as, capacity, weight, and cost between aluminum (Al) and copper (Cu) to consider for an electrical application.  Al was more prevalent in the past for products such as bus bars, fuses, and breakers. Overtime, some designers have changed components from Al to Cu. Today, due to cost stability and coating some designers are switching back.  Misconceptions about the properties between Al and Cu can arise due to different grades of metals used in different electrical applications. The Cu used in wire and electrical equipment is nominally pure. Pure Al, however, is often not strong enough for electrical applications. Also, keep in mind that different alloys have changed over time and on account of evolving applications. Different Al alloy properties will also change, depending on processing. For example, Al 6101 is stronger than Al 1350. Yet heat-treating Al6101 hardens it and improves its strength....

Men and women are different in several respects, but the moment you get on to the

Men and women are different in several respects, but the moment you get on to the subject of shoes, a chasm opens between the two sexes; it’s only for women that shoes become an all-consuming obsession. Shoes can cost a fortune; yet while money itself does not bring happiness, a pair of new shoes bring on a kind of exaltation. Unlike clothes, shoes have a distinct advantage. Whether you’re fat or thin, short or tall, beautiful or ugly, you can buy all the shoes your heart desires. They are capable of making you feel sexy, elegant or sporty at a single stroke. For a long time, the obsession with luxury shoes has been the prerogative of a select tribe of actresses, socialites, It-girls and millionairesses whose members could be identified by the accessories with which they adorned themselves. Their distinguishing tattoos were the label – Hermes, Gucci, Caovilla, Ferragamo, Blahnik, Laboutin – which they procured by putting their names down on the special waiting lists of international boutiques. Our intimate relationship with shoes begins shortly after we learn to walk. As soon as we want to feel “grown-up,” we slip on a pair of our mother̵...
