Recycling Metals from Water with a Tiny Helper

January 18, 2026

Scientists made a cool new tool to clean up heavy metals from water. They used tiny plants called diatoms, mixed them with some special stuff, and created a super material. This material can grab onto metals like cadmium, copper, and lead. The team tested this new material in different conditions.

Cleaning Up Water: The Science Behind Adsorption

December 26, 2025

Adsorption is a big deal in water cleanup. It's like a magnet that pulls out nasty stuff from water. But, it's not as simple as it sounds. There are three big things that make it work: how much stuff can stick to a surface, how much stuff is left in the water, and how the stuff sticking to the surfa

How Tiny Pollutants Stick to Wastewater Cleaners

December 9, 2025

Nanoparticles, tiny pollutants, are a big worry. They can harm nature and people over time. A recent study looked at how these nanoparticles stick to and come off of aerobic granular sludge (AGS) in wastewater treatment. AGS is a special kind of sludge used to clean water. The study found that the

Clean Water Quest: Turning Farm Waste into a Pollution Fighter

December 4, 2025

Wheat straw, often seen as farm waste, has a new role in cleaning up water. Scientists have found a way to tweak it chemically to soak up a harmful dye called Rhodamine B. This dye is tough to break down and can be toxic. The modified straw, now called EWS, is a game-changer. EWS is made by treatin

Capturing Rubidium: A Smart New Way to Extract Valuable Ions

December 2, 2025

Rubidium is a valuable element found in salt-lake brines, but extracting it has been a tough job. The usual methods aren't great at picking out rubidium from other stuff like sodium, potassium, calcium, and magnesium. But now, there's a new trick: using a special material with lots of sulfonic acid

Sunflower Straw: A Green Solution for Oil Spills?

November 7, 2025

Sunflower straw, a common agricultural waste, has been given a new purpose. Scientists have been experimenting with it to clean up oil spills. They treated the straw with two different chemicals: silanization and acetylation. The goal was to see how well the treated straw could soak up oil. The exp

Nickel Catalysts Get a Boost from Halogen Friends

October 20, 2025

Nickel catalysts are not as good as their noble metal counterparts for hydrogen oxidation in alkaline environments. They only have 1-2% of their activity. This is a problem because scientists don't fully understand why. But recent research sheds some light on this issue. The study looked at how dif

How Dialysis Filters Affect Medicine Levels in Sick Patients

July 6, 2025

In seriously ill patients, the way the body processes medicine can change. This is especially true for a drug called caspofungin. Doctors use a special machine called continuous renal replacement therapy (CRRT) to help these patients. The machine has filters made from a material called polyacrylonit

CO2 Capture: The Waterproof Solution

June 21, 2025

The challenge of capturing carbon dioxide from industrial exhaust gases is real. The main issue is humidity. Most materials used to trap CO2 are porous. They have tiny holes that can soak up water more easily than CO2. This is a problem. Water can crowd out CO2, making it harder to capture. It also

How Water Affects Alcohol Adsorption in Zeolites

June 11, 2025

Zeolites are like superheroes in the chemical world. They are used to separate and process things in both gas and liquid forms. They are known for their special abilities: they can pick out specific molecules, soak up lots of stuff, be reused, and stay stable. One type of zeolite, called H-MFI, has
