The team came up with a unique method for measuring the electric potential distribution across a ferroelectric capacitor, which could lead to the creation of memory orders of magnitude...

I've been all over the Internet and am having trouble finding definitive answers regarding a couple motor capacitors. The first cap (capacitor) is in a PSC (Permanent Split Capacitor) motor, and is rated @ 7.5 uF, 370 VAC. Researching this one was a bit of a "journey", and I believe I've answered most of my questions correctly -- I hope! Basically, it appears to me that the specs for a cap in a PSC motor are similar to those in an electric motor that uses a "run" capacitor, since in both cases the cap is in use anytime the motor...

A team of researchers at the Israel Institute of Technology has developed a new capacitor with a metal-insulator-semiconductor (MIS) diode structure that is tunable by illumination. The capacitor, which features embedded metal nanoparticles, is similar to a metal-insulator-metal (MIM) diode, except that the capacitance of the new device depends on illumination and exhibits a strong frequency dispersion, allowing for a high degree of tunability. This new capacitor has the potential to enhance wireless capability for information processing, sensing and telecommunications. The researchers report their findings this week in the Journal of Applied Physics. "We have developed a capacitor with the...

Flexible polymer nanocomposite thin films for high-temperature high-voltage capacitive energy storage. Credit: Q. Li +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ A team of researchers at the Pennsylvania State University has created a new polymer that is able to store energy at higher temperatures than conventional polymers without breaking down. In their paper published in the journal Nature, the team describes how they created the polymer and why they believe it could be useful in many products. Harry Ploehn with the University of South Carolina offers a brief history of polymers created for use in electronics, in a News & Views piece in the same journal...

Samples of the new hybrid sol-gel material are shown placed on a clear plastic substrate for testing. Credit: John Toon, Georgia Tech ================================================================================================================= Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. If the material can be scaled up from laboratory samples, devices made from it could surpass traditional electrolytic capacitors for applications in electromagnetic propulsion, electric vehicles and defibrillators. Capacitors often complement batteries in these applications...

By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The pores provide a large surface area for the electrode materials to attach to, leading to an increase in ion movement between the electrodes and the electrolyte that fills in the pores. Overall, the new supercapacitor exhibits a performance that is superior to that of one made of the same electrode materials but without the sponge. The researchers, led by Jun Ma at the University of South Australia, have published their...

Some of the great scientific breakthroughs of the last century came about entirely by accident. Many of you are probably familiar with the origins of the Post It Note, and how it was invented as a result of a failure when attempting to create a super strong adhesive. Well, there may be another such story taking place in the present day. Scientists working with carbon compounds developed Graphene, a safe substance with a lot of structural strength for very little mass and weight. And then some wise guy discovered that it had another use. The recap: Graphene, a very simple...

Small is big for Murata: The Japanese electronics maker has developed the world's tiniest version of a component known as the capacitor. And that's potentially big business. Capacitors, which store electric energy, are used in the dozens, even in the hundreds, in just about every type of gadget—smartphones, laptops, parts for hybrid cars, medical equipment and digital cameras. Smaller componentry allows for other innovations and improvements from thinner devices to longer battery life. The latest capacitor, measuring just 0.25 millimeter by 0.125 millimeter, is as tiny as the period at the end of this sentence. Murata Manufacturing Co.'s focus on...

EEStor is the urban legend of a startup that is said to be building a supercapacitor material that would store more energy and charge and discharge faster than previous materials by a factor of ten. If true, it could change the technology of electric vehicle charging and utility-scale energy storage. We've made repeated attempts to contact the company and its CEO, Dick Weir, to no avail. Here is some of our EEStor coverage from last year, which includes a musical lament. The firm's website is no longer online and the usual fevered musings of the EEStor blogosphere have slowed. Here's...

If optimized, this new technology could fully charge consumer electronic devices almost instantaneously.Drawing on the layered design of tear-inducing onions, scientists have created a new super capacitor that is powerful enough -- and cheap enough -- to replace the larger, heavier capacitors used in consumer electronics such as computers and cells phones. If commercialized, the new super capacitor could be fully charged in a second and, coupled to a normal battery, provide enough energy to power a cell phone for weeks or a laptop battery for days. "If you open any computer, you will see a lot of these...

does anyone have a source for capacitors for lamps? i have a lamp that i like and paid a lot of money for. the capacitor burned out. i've checked numerous suppliers on the web. most don't want to be bothered. lamp stores want to sell you a new lamp. the capacitor is taiwanese: zing ear #256 thanks, ken
