Researchers Propose Method to Increase Charge of Supercapacitors

Growth of polarizability or permanent dipole moment of cations leads to considerable growth of differential capacitance

Researchers from HSE MIEM and the Institute of Non-Classical Chemistry in Leipzig have proposed a new theoretical model of supercapacitors that takes into account the properties of a cation, which considerably impacts the electric differential capacitance of supercapacitors. This is the first publication of

Stanford Engineers Create Perching Bird-Like Robot

The grasping robot that Stanford engineers developed based on studies of birds.

Like snowflakes, no two branches are alike. They can differ in size, shape and texture; some might be wet or moss-covered or bursting with offshoots. And yet birds can land on just about any of them. This ability was of great interest to the labs of Stanford University engineers Mark Cutkosky and David Le

Figure 1: The system block diagram (left) showing three main components: the two converter modules, each with a gate driver, and the controller. The power modules mounted on the cold plate (A), and then in the power core with gate drivers (B), are also shown outside the dual inverter enclosure (C). Handles and feet are provided for portability, (D) shows the 204 mm x 267.5 mm cross section

The traction drive is where nearly all of an electric vehicle’s (EV’s) energy is put to use. The drive system must, therefore, perform with the highest possible efficiency while occupying the smallest possible space with the lowest weight — all to maximize the EV range. With the use of dual drives to enhance tr

 The Automotive Electronics Bust Was Predictable
As I write this, we are locked in the “bust” part of the boom-bust hysteretic cycle that plagues the electronics component industry.
