One feature of supramolecular chemistry is that of self-assembly, in which the structure forms spontaneously as a consequence of the nature of the molecules. Weak non-covalent bonds are fundamental for designing self-assembled organic structures with potentially high responsiveness to mechanical, light, and thermal stimuli. The contributions of multiple weak interactions control the ability of the […]

Lithium-ion batteries have remained unrivalled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations. However, they suffer from some important disadvantages that are difficult to ignore. For one, lithium is rather expensive, and the fact that it is being mined at […]

Nonlinear optics is concerned with the optical properties of matter subjected to intense electromagnetic fields. For nonlinearity to manifest itself, the external field should not be negligible compared to the internal fields of atoms and molecules of which the matter consists. Lasers are capable of generating external fields sufficiently intense for nonlinearity to occur. Actually […]

At the end of 2022, researchers at Lawrence Livermore National Laboratory announced they had observed a net energy gain through nuclear fusion for the very first time. This monumental milestone toward fusion energy represents a huge leap forward in powering our homes and businesses with the carbon-neutral energy source. But converting this scientific achievement into […]

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. The study of enzymes has provided us many of the prototypical concepts of catalysis, including the idea that a catalyst lowers the barrier to reaction and thereby accelerates the approach to chemical equilibrium, without altering […]

Water has puzzled scientists for decades. For the last 30 years or so, they have theorized that when cooled down to a very low temperature like -100 ºC, water might be able to separate into two liquid phases of different densities. Like oil and water, these phases don’t mix and may help explain some of […]

Nanothreads are one-dimensional covalently bonded materials, with all “backbone” bonds saturated in the organic sense, the first of which was made from polymerization of benzene in the solid state. Nanothreads are thicker than conventional hydrocarbon polymers such as polyethylene and thinner than traditional nanowires: as ladder polymers, they are examples of the thinnest possible rigid […]
