Renewable energy and electric cars are driving demand for batteries with denser energy storage than standard lithium-ion batteries. Ions that can carry more than one charge, such as calcium and ...

Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the ...

Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium ...

Researchers at The Hong Kong University of Science and Technology have developed a new type of calcium-ion battery that could challenge lithium-ion technology by improving stability and performance.

Quantum sensing has long promised exquisite sensitivity, but in the real world, environmental noise usually buries the very signals researchers want to see. A new experiment using just three trapped ...
