Researchers turn plastic bags into battery components
Researchers from Purdue University have created a new technique for converting discarded plastic bags into carbon chip anodes for lithium-ion batteries that power smartphones and other devices.
Printable stainless-steel material withstands harsh environments
A new stainless-steel material designed for use with Desktop Metal's 3D printing system is suitable for extreme temperature, highly corrosive and marine-grade applications.
Marines 3D print a bridge in the field
The ACES printer uses concrete made with aggregate, rather than paste or mortar, and can create other types of structures such as obstacles, protective structures, vaults, culverts and beams.
Metal forming machine tools — Part 1: Bulk metal
A wide variety of machine tools exist to convert a bulk metal into semi-finished stock and near-net-shape parts.
Medals at 2020 Tokyo Olympics to be made from e-waste
According to organizers of the 2020 Tokyo Olympics, all of the Olympic and Paralympic medals — bronze, silver and gold — will be composed of recycled electronic waste.
Video: Converting waste plastic into clean fuels and useful products
The method could help with pollution in oceans and landfills.
Researchers create self-healing 3D-printed material
The 3D-printed rubber material can self-repair through a 3D-printing process called photopolymerization.
Elastomer sheets as shape-shifting actuators
The shape of a flat sheet of elastomer is changed using actuation that is fast, reversible and controllable by an applied voltage.
Robust salinity sensor stands up to marine conditions
Biofouling-independent salinity sensing is achieved by application of a laser irradiation process to a flexible polyimide substrate.
Graphene biosensor breathes new life into lung cancer diagnosis
The device demonstrated improved detection accuracy for three of the most common lung cancer biomarkers in human breath.
New carbon capture sorbent promises efficient emission control
A new class of organic compounds captures carbon from coal-fired power plant emissions in a process that is less energy intensive than existing methods.
Japanese company makes life-like masks to train facial recognition technology
A mask-making company in Japan produces life-like masks via 3D printing for applications that include training facial recognition technology software.
Implant combines bioactive glass with copper to fight bone infection
The glass serves as a delivery platform for copper ions, which promote new blood vessel and bone growth and have proven antibacterial properties.
Watch a self-healing, oil-based barrier coating
A new coating for metal self-heals within seconds when scratched, scraped or cracked.
Making it stick: The many uses of cyanoacrylate adhesives
Cyanoacrylate, commonly known as superglue, is a one-part adhesive that can form strong bonds with a wider variety of materials than most other types of adhesives.
Photographer builds 11 ft wave of plastic straws to raise awareness about plastic pollution
A photographer hoping to raise awareness about the issue of plastic pollution has constructed an 11 ft art installation made almost entirely of plastic straws.
Graphene dough easy to transport, store and mold
A non-solution-based processing route produces graphene oxide in a dough state without the use of binders.
Metallic wood is as strong as titanium but four times lighter
Engineers have built a sheet of nickel with nanoscale pores akin to natural wood that makes it lighter than the strongest metal.
Study reveals "bug bombs" do not kill roaches
Research from North Carolina State University reveals that total release foggers, otherwise known as “bug bombs,” fail to kill cockroaches in indoor environments.
Bio-inspired coatings reduce ship drag and CO2 emissions
Application of high-tech coatings to hulls reduces the effect of drag, and in turn lower energy use, operating costs and emissions.
