Three-sided pyramids form 2D structures

Control Engineering

Chiral structures are mirror opposites, similar forms, like right and left hands, that can’t be superimposed on one another. That made it doubly surprising that they fell so easily into chiral forms during experiments when evaporated onto a surface, Jones said. This is unexpected,” he said. Courtesy: Z.

Integrated stepper motors trim accurate metal forming costs

Control Engineering

To reduce design costs and maintain quick and precise positioning of backgauges before each metal-forming cycle, CI chose integrated stepper motors. . Computer cases and other metal electronics enclosures . The all-in-one format with electronics integrated into the motors makes for a cost-effective and compact solution. .

2D boundaries could create electricity

Control Engineering

The red areas are electro-deficient, the green is electron rich. An image from a Kelvin probe force microscope shows the electronic potential distribution across the metallic and semiconductor phases of MoTe2. This allows one to engineer materials in 2D to create device architectures that could be unique in electronic applications.”.

Wearable bioelectronic device capable of tracking multiple vital signs developed

Control Engineering

Its integrated antibacterial and antiviral properties can also help prevent harmful pathogens from forming on the surface of the skin underneath the device during extended use. This is because people can feel about 20 kilopascals or more of pressure when something is stretched on their skin, and this material creates less pressure than that.”

Thin film growth technique is the result of microscopic holes

Control Engineering

These thin films could play an important role in flexible or wearable electronics and in the development of unique multilayer devices for next-generation computing. And that’s when we noticed that 10-nanometer pinholes were forming because the oxide was bursting out of the substrate.”.

Solving the puzzle of 2D materials disorder

Control Engineering

In science, disorder refers to imperfections or nearby charges that might scatter the otherwise straight path of an electron. The researchers then utilized an empirical rule to piece together all the curves until they formed a complete picture. Each individual conductivity curve resembles a puzzle piece.

Robotic grippers developed to pick up delicate, heavy objects

Control Engineering

The design for the new grippers builds on an earlier generation of flexible, robotic grippers that drew on the art of kirigami, which involves both cutting and folding two-dimensional sheets of material to form three-dimensional shapes. graduate from NC State.
