A fluorine-free, water-processable binder could simplify lithium-ion battery manufacturing and recycling. Developed at the University of California San Diego, it allows electrode coatings to separate from metal foils in water, while laboratory tests showed comparable initial battery performance and improved capacity retention.

Researchers have developed a novel class of nanotube membranes that enable ultrafast ion transport. The findings open new pathways for high-efficiency clean energy generation, lithium recovery and molecular separation.

Without high-performance storage solutions, the transition away from fossil fuels will not be possible. For this reason, battery production and it's monitoring are critical factors. Conductivity and pH are key parameters in this context.

A new solar-powered desalination system developed at the University of Rochester can produce fresh water from seawater without chemical additives or brine discharge. At the same time, the process recovers salts and valuable minerals that would otherwise remain a difficult waste stream.

Researchers have developed a new type of 3D-printable material that mimics the human tissue’s ability to sort and filter, allowing certain molecules to pass through while keeping others out. This material can be used in a variety of applications across medicine, water and robotics.

Although the pH scale traditionally ranges from 0 to 14, highly concentrated acids can have negative pH values. Accurately measuring these extremes poses technical challenges for standard electrodes. This article explains how specialized sensors and modern methods enable reliable measurements in such chemical extremes.

Tattoo-like leaf sensors and stretchable stem bands could help farmers detect drought, salinity and other crop stresses before visible damage appears. Powered by moisture evaporating from the plant, the battery-free wearables monitor water loss and growth in real time.

Engineers at the University of California San Diego have developed a new design approach for lithium-aluminum alloy electrodes that could dramatically boost the performance and lifespan of solid-state batteries.

Without batteries, many modern devices would be inoperative. In this article, learn why pH level and conductivity are crucial parameters for battery performance.

Measuring pH is not just a routine procedure in the laboratory; it is also a crucial parameter for assessing the condition of ecosystems, such as lakes, in the field. But what criteria should one use to select the appropriate pH meter? In this article, we have compiled some of them.
