Lithium-sulfur batteries are a promising candidate of next-generation storage devices due to their high theoretical specific energy ~2600 Wh kg −1 and the low cost of sulfur 56.

Batteries represent one of the energy storage devices that stored the energy in form of chemical energy and converted it to electricity via redox reactions or intercalation processes as observed generally in lithium ion batteries (LIBs) and in sodium ion batteries (SIBs) (Figure 2a,b). They consist of two electrodes separated by an electrolyte.

It''s estimated that humans are producing the equivalent of 10 million Blu-ray discs'' worth of data every single day - and all of those ones and zeroes have to be stored somewhere. Now researchers in the UK just might have the solution: a five-dimensional (5D) digital data disc that can store 360 terabytes of data for some 13.8 billion years.

The system is called a "5D" data storage system, for the two extra dimensions (in addition to the standard three spatial dimensions) that polarization enables data to be encoded into the disc.

Due to the air-quartz interface, causing approximately 4% of the incoming energy to be reflected and lost, these lines converge toward the maximum value η thermal = 0.96. The thermal trap effect allows higher maximum T to be reached in stagnation conditions, for all considered concentration ratios, in line with previous findings.
