Measuring pH in hand sanitizer: Choosing the right sensor
Consider these guidelines for measuring pH in hand sanitizers that are alcohol-based and contain components such as active ingredients, humectants and excipients.
Beer yeast repurposed for filtering out lead in water
The researchers suggest that the tons of discarded yeast from beer breweries could potentially filter out lead from contaminated water quickly.
Eggshells eyed for recovering rare earth elements
The approach promises to offer an environmentally friendly method for extracting the REEs necessary for developing the permanent magnets used in electric cars and wind turbines.
Copper-treated stainless steel promises to kill bacteria without antibiotics or chemicals
The new method relies on the natural antibacterial properties of copper in combination with small needle-like structures etched on the surface of stainless steel and designed to kill harmful bacteria including E. coli and Staphylococcus.
New Lego-like bricks built from 90% recycled plastic waste
Dubbed PLAEX-crete — which stands for PL-astic, A-ggregate, and EX-truder — the blocks are described by the startup as lightweight, durable and eco-friendly and are intended to make the construction process easier.
Spider silk-inspired sensors imperceptible to the wearer
Inspired by the web structures created by spiders using minimal material, the fibers used to construct these sensors are roughly 50 times thinner than human hair.
A second life for spent coffee grounds
Spent coffee grounds possess several highly desirable chemical components that are potentially useful for some other applications with little or nothing to do with consuming.
Fundamentals of electrochemical corrosion
Engineers are leveraging the interplay between corrosion and electrical resistance to develop more effective strategies for managing corrosion. These strategies include material selection, protective coatings, cathodic protection, and environmental control, all of which will be covered in this article.
Thin film can turn normal glasses into night vision glasses
According to the researchers, the filter is substantially thinner — even thinner than a piece of cling wrap — and could eventually be placed onto regular eyewear.
A spectroscopic stampede against illegal ivory trade
The laser-based method devised to distinguish between illegal elephant ivory and legal mammoth tusk ivory can be of value in stemming illicit trade.
Partners to co-produce titanium fasteners for US Army
These components will be engineered for the U.S. Army Ground Vehicle Systems Center.
These blades 'wood' improve wind energy sustainability
Wooden blades have been installed on an existing wind turbine as a sustainable alternative to fiberglass and carbon fiber-based components.
Nuclear and space-proven seals poised to take on hydrogen energy safety challenges
Technetics, with their pedigree in nuclear and aerospace sealing applications, has the experience and expertise to meet the challenge of hydrogen safety and containment head-on.
Video: Nanogenerator converts carbon dioxide into electricity
A system that yields the benefits of electric power production and carbon dioxide capture has been engineered by researchers in Australia.
This wall-climbing robot takes inspiration from snails
This design allows robots to easily scale walls, potentially paving the way for robots capable of traveling on the surfaces of wind turbine blades, ship hulls, aircraft and glass windows of skyscrapers to perform autonomous inspections.
Fallen leaves transformed into sensors
The researchers concluded that the electrochemical sensors derived from fallen tree leaves demonstrated satisfactory analytical performance and notable reproducibility.
Soft robot implants bend, expand, twist to deliver meds in the body
The researchers noted that the soft robots can perform various well-controlled movements — such as bending, expanding and twisting — inside biological environments.
MIT engineers develop adhesive anti-fibrotic hydrogel
The adhesive anti-fibrotic hydrogel protects such devices by preventing the immune system from recognizing and subsequently attacking it and avoiding fibrosis.
A light bulb moment for rare Earth recycling
A relatively simple process recovers rare-Earth metals from spent fluorescent bulbs.
Halliburton launches new cement system for offshore, remote locations
According to the company, the single-sack packaging enables proactive storage in offshore and remote locations.
