Plastics, structural polymers made from monomers, are ubiquitous in modern life and have unique benefits. At their end of life, they must be reused or recycled in ways not yet implemented today. In many cases, the polymerisation process can be efficiently reversed via depolymerisation recycling to regain monomers at the original quality level. As such, depolymerisation is a key circularity...

According to Socrates, "The secret of change is to focus all of your energy not on fighting the old, but on building the new." The new includes healthier living and sounder engineering. Specifically, we strive to generate cleaner energy and spread it to all corners of the world; improve understanding and care for the land, sea, and air; transform waste...

The book presents much creative, original and stimulating ideas on the various approaches which could be taken to tackle five important open problems in mathematics, viz., the twin primes, Goldbach and Polignac’s conjectures, and the Navier-Stokes equations and turbulence, and the Riemann hypothesis, which are both Millennium Prize problems. Technical areas such as calculus, differential equations, group theory/symmetry and complex...
