Chitin and its derivative chitosan are natural polymers found in crustaceans and elsewhere in nature. Engineers at the University of Maryland devised a way to make zinc-based batteries more durable by incorporating chitosan. This could pave a way for alternatives to lithium-ion batteries, which are becoming increasingly expensive, in addition ...

Calcium is the major component of hardness in water and is usually in the range of 5 - 500 mg/I, as CaCO3. Calcium is derived from nearly all rock, but the greatest concentrations come from limestone and gypsum. Calcium ions are the principal cations in most natural waters. Calcium reduction is required in treating cooling tower makeup.

The formation of calcium carbonate deposits also depends strongly on the substrate [11,12]. It is interesting that strongly adhering calcium carbonate forms even in PVC pipes used for the transport of drinking water, as shown in Figure 1.7. The increased calcium and carbonate concentration levels are responsible for

The less costly low-porosity sorbents, calcium carbonate and calcium oxide also performed well. Calcium carbonate reached a relative utilization of 54% in the mid-temperature range, while the calcium oxide reached an 80% relative utilization at the lowest temperature examined. The data matched theoretical predictions of sorbent utilization ...
