Researchers studying nanowires have found a battery material that can be recharged for years, even decades.

In traditional Chinese culture, qi or ch’i is believed to be a vital force forming part of any living entity. Qi translates as “air” and figuratively as “material energy”, “life force”, or “energy flow”. Qi is the central underlying principle in Chinese traditional medicine and in Chinese martial arts.

Scientists and non-scientists alike have long been dreaming of elements with mighty properties. Perhaps the fictional materials they have conjured up are not as far from reality as it may at first seem.

The periodic table of elements has become one of the defining symbols of chemistry. It is, of course, a handy chart of the building blocks that make up absolutely anything and everything around us, but it is also the outcome of the work of a huge number of scientists, which led to the current understanding of the elements’ atomic structure and behaviour. For those who like organization, patterns and chemistry, what’s not to love?

The Fibonacci numbers are ubiquitious in nature and mathematics. This palmsize sculpture encapsulates the generating matrix for these numbers. In a problem published 800 years ago, Leonardo of Pisa, a.k.a. Fibonacci formulated his famous rabbit problem: beginning with a newborn fertile pair of rabbits, how many pairs will accumulate monthly if each pair produces another pair from their second month on? The solution of this leads to a recursively defined sequence of integers, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, … This sequence has the property that two consequtive terms added give the next term.

The Fibonacci Matrix Torus has raised (esker) curves or continuous crests which wind around the torus either the short way or both the short and long way. This gives the matrix with first row (0, 1) and second row (1, 1) respectively. The powers of this matrix give matrices whose entries are always Fibonacci numbers.

A research group from RIKEN and Kyushu University has developed a new type of material, based on ethylene, which exhibits a number of useful properties such as self-healing and shape memory. Remarkably, some of the materials can spontaneously self-heal even in water or acidic and alkali solutions. The new material is based on ethylene, a compound that is the source of much of the plastic in use today.

Materials that can self-heal have become a popular area of research during the last decade, and a variety of materials have been developed. However, most of the self-healing materials reported to date have relied on sophisticated designs that incorporate chemical mechanisms into polymer networks, such as irreversible or reversible covalent-bond formation, hydrogen bonding, metal-ligand interactions, or ionic interactions. As a result, they require some external stimulus, such as heat or pressure, to prompt them to heal, and in most cases, they do not function in water, acid or alkaline solutions because the chemical networks cannot survive such conditions. The ideal is to create a material that possesses sufficient toughness and can autonomously self-heal under various conditions.

A new greener, stronger and more durable concrete that is made using the wonder-material graphene could revolutionise the construction industry.

Experts from the University of Exeter have developed a pioneering new technique that uses nanoengineering technology to incorporate graphene into traditional concrete production.

The new composite material, which is more than twice as strong and four times more water resistant than existing concretes, can be used directly by the construction industry on building sites. All of the concrete samples tested are according to British and European standards for construction.
