Outsourcing Plasma Treatments for Surface Modification

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_02
Published 2020-02-01 by SAE International in United States

In manufacturing, plasma treatments are often utilized to solve problems that cannot be resolved other ways. Whether attempting to improve adhesion of dissimilar materials; depositing coatings; cleaning surfaces; applying a protective coating that repels water, for example, or biological fluids; or enhancing surface wettability or functional coating, plasma treatments often add significant value to products.

Insect-Inspired Motion Sensing

  • Magazine Article
  • TBMG-35993
Published 2020-02-01 by Tech Briefs Media Group in United States

Researchers have taken inspiration from flying insects to demonstrate a miniaturized gyroscope, a special sensor used in navigation technologies. Gyroscopes sense rotational motions to provide directional guidance without relying on satellites, so they are immune to signal jamming and other cyber threats, making them ideal for aircraft and submarines.

Robot Circulating Liquid Stores Energy and Provides Power

  • Magazine Article
  • TBMG-36003
Published 2020-02-01 by Tech Briefs Media Group in United States

Humans and other complex organisms manage life through integrated systems. Humans store energy in fat reserves spread across the body and an intricate circulatory system transports oxygen and nutrients to power trillions of cells. But with an untethered robot, things are much more segmented with batteries, motors, and cooling systems scattered throughout.

3D Printing Technique Produces “Living” 4D Materials

  • Magazine Article
  • TBMG-35958
Published 2020-02-01 by Tech Briefs Media Group in United States

Repairing and reusing plastics and delivering cancer drugs more effectively are two of the many potential applications a new 3D/4D printing technology might have. The technology merges 3D/4D printing and photo-controlled/living polymerization — a chemical process to create polymers. 4D printing is a subset of 3D printing where the printed object can transform its shape in response to certain conditions. The new method uses visible light to create an environmentally friendly “living” plastic or polymer. Polymers can be synthetic, such as plastic, as well as biological; for example, DNA.

In-Situ Resource Utilization (ISRU): Methylotrophic Microorganisms Expressing Soluble Methane Monooxygenase Proteins

  • Magazine Article
  • TBMG-35812
Published 2020-01-01 by Tech Briefs Media Group in United States

Long-duration missions to planetary bodies and deep space will require new technological developments that support human habitation in transit and on distant bodies. Microorganisms are unique from the standpoint that they can be employed as self-replicating bio-factories to produce both native and engineered mission-relevant bio-products. Methane (CH4) usage in In-Space Manufacturing (ISM) platforms has been discussed previously for human exploration and has been proposed to be used in physicochemical systems as a propulsion fuel, supply gas, and in fuel cells.

Magneto-Optic Biosensor Using Bio-Functionalized Magnetic Nanoparticles

  • Magazine Article
  • TBMG-35827
Published 2020-01-01 by Tech Briefs Media Group in United States

Magnetic nanoparticles are leading to the development of more sensitive, rapid, and cost-effective biological sensors. These sensors can be used for a variety of applications including the detection of medical conditions and bioterrorist threats.

Facility Focus: National Oceanic and Atmospheric Administration

  • Magazine Article
  • TBMG-35797
Published 2020-01-01 by Tech Briefs Media Group in United States

In 1807, President Thomas Jefferson founded the U.S. Coast and Geodetic Survey to provide nautical charts to the maritime community for safe passage into American ports and along the coastline. The Weather Bureau was founded in 1870 and one year later, the U.S. Commission of Fish and Fisheries was founded. Individually, these organizations were America's first physical science agency, America's first agency dedicated specifically to the atmospheric sciences, and America's first conservation agency.

Virtually Optimizing Metasurface Topology with a Genetic Algorithm

  • Magazine Article
  • TBMG-35764
Published 2020-01-01 by Tech Briefs Media Group in United States

Often in engineering, we look to the natural world to find inspiration for new ways to approach our design problems. Whether we are taking inspiration from fluid flow around wings to inform a system for cooling devices, studying slug slime to invent better medical adhesives, or designing the nose of a bullet train to resemble the beak of a bird, nature holds the key to even the most elusive design solutions.

Breathable Electronic Skin Using Nanofiber Substrate

  • Magazine Article
  • TBMG-35807
Published 2020-01-01 by Tech Briefs Media Group in United States

Wearable electronic devices for health monitoring using electronic skin have emerged but most electronic skin-related technologies utilize materials such as plastic or rubber that can cause skin irritation or interfere with metabolism when attached to skin or biological tissue.
