New detector seeks out nuclear material hiding in air ducts
The ORNL team developed the new monitor, which was designed to check every minute or every second for the accumulation of nuclear material in the air ducts.
New bio-based plastic becomes fertilizer after processing
To tackle the growing global plastic waste problem, researchers from Chiba University, Tohoku University and the University of Tokyo have developed a bio-based plastic that can be converted into fertilizer. The researchers found that a component of the plastic can be chemically converted into
Eucalyptus bark waste gets a second life as a carbon filter for cleaner air, water
The team found a simple way to transform the bark into a porous carbon material.
Powerful self-cleaning tech defeats mineral buildup to capture ocean CO2
The new electrochemical process combines hydrogen gas and redox salt looping to capture carbon dioxide from seawater via controlled pH swings.
When should you replace your pH sensor?
It depends largely on its usage.
Fan anatomy
Every part of a fan plays a role in how it performs. This article takes a closer look at the fan anatomy that generates airflow.
Why cleanroom environmental control necessitates an expert approach
Advanced HVAC systems help compounding pharmacies maintain cleanroom conditions, ensuring contamination control, regulatory compliance and precise environmental management.
Butterfly-inspired technology could transform air-quality monitoring
In trials detecting SARS-CoV-2, the device achieved 100 times greater sensitivity than conventional pump-based samplers, the team revealed.
New membrane strips over 99.99% of oil from seawater while boosting evaporation
The separation of the membrane’s functions across the two layers prevented oil separation and solar heat generation from interfering with each other — which is a common obstacle for single-layer designs.
New system strips 85% of salt, 92% of heavy metals from wastewater in 4 hours
Wastewater from electronics manufacturing and metal processing contains high levels of salt and toxic heavy metals and expensive treatment processes leave behind concentrated brine and hazardous sludge. This process might recover some value.
Waste plastic as a hydrogen source
Instead of becoming a persistent environment pollutant or requiring complex, energy-intensive processes for recycling, plastic waste can represent a source of hydrogen production.
Ammonia from wastewater: How we’re turning a pollutant into fertilizer and clean fuel
Research demonstrates how new catalysts and renewable electricity can convert nitrate, one of the most common water pollutants, directly into ammonia.
Blueair launches wool-based EcoLast air filter for greener air purification
Blueair, alongside Lanaco, a New Zealand-based wool technology company, created a bio-based, USDA-certified wool filter that uses biodegradable alternatives.
Waste cotton stalks and eggshells turned into reusable biochar for wastewater antibiotic removal
The team developed a ß-cyclodextrin modified calcium-rich cotton-stalk biochar, called Ca@CBC/ß-CD, which was prepared via a microwave-assisted crosslinking process.
Shoring up water reuse with PFAS removal
An initiative to treat municipal wastewater to drinking standards before recharging aquifers will benefit from advanced ion exchange technology.
Filtering PFAS with “molecular Velcro”
A new gel-based material filters PFAS “forever chemicals” from water more efficiently than many widely used commercial options.
Why transparency is needed in lithium-ion battery recycling
A new GAIA report finds that battery recyclers report almost nothing about what they release, recover or burn, leaving regulators and communities to find out the hard way.
The most common errors in pH measurements and how to avoid them
Explore the most common errors encountered in pH measurements, understand why they happen and discuss best practices to minimize these errors for more reliable results.
UK to advance hydrogen for industrial heating
A real-world, industrial-scale testbed will help manufacturers trial hydrogen fuel-switching in a controlled environment.
Water treatment via photocatalytic platform: No chemicals needed
A flexible microreactor technology effectively eliminates contaminants from water using sunlight.
