Capacitors with Very Low Loss: Cryogenic Vacuum-Gap Capacitors
We report on measurements of capacitors with about 1 pF of capacitance, which have unmeasurably small leakage at very low frequencies, placing a lower bound of about 1019[2 on the parallel resistance at an effective frequency of 1 mHz. These measurements are made possible by two themes: the use of vacuum-gap capacitors (i.e., no dielectric material, operated in vacuum), and detection of leakage...
متن کاملGet Happy, Get Rich
The world’s poor, whether they live in dangerous urban slums or in the remote countryside, are often in dire need of food, clean water, and basic medications. So it might appear misguided to argue that mental health should be a primary rather than secondary concern in developing countries. But the reality is that mental health is not just a First World problem: disorders such as depression are ...
متن کاملCarbon Nanotube Capacitors
Capacitors are important components in many integrated circuits. They serve numerous roles in analog and mixed signal circuits, including switched capacitor filters and sampleand-hold circuits. In addition, capacitors provide a vital role in the decoupling of microprocessors, digital signal processors, and microcontrollers from power supply variations. Traditional integrated circuit capacitors ...
متن کاملBatteries and electrochemical capacitors
solar and wind power, offers enormous potential for meeting future energy demands. But access to solar and wind energy is intermittent, whereas electricity must be reliably available for 24 hours a day: Even second-to-second fluctuations can cause major disruptions that cost tens of billions of dollars annually. Electrical energy storage devices will therefore be critical for effectively leveli...
متن کاملOptimal charging of capacitors
Finite-time thermodynamics is illustrated by some examples of process optimalization. The objective is minimum entropy production during an electrical process, i.e. the charging of a capacitor. Non-linear electronic processes are investigated in particular, because of their importance in computers and displays.
