An academic has formulated a pioneering theory that furnishes a universal technique for foreseeing melting points, tackling a century-old hurdle in physics and providing significant advantages to the sphere of materials science.

This challenging, enduring problem in physics has been finally solved by Professor Kostya Trachenko of Queen Mary University of London’s School of Physical and Chemical Sciences. His study, appearing in the Physical Review E, presents a general theory for predicting melting points, a basic property that has confounded scientists for over a hundred years.

The comprehension of the three basic states of matter - solids, liquids, and gases – for many years, has been dependent on temperature-pressure phase diagrams. These diagrams illustrate the circumstances under which each state exists, with clear lines distinguishing them. However, a vital line, the melting line – that signals the transition from solid to liquid – lacked an all-inclusive description.

The theory of Professor Trachenko addresses this omission. By formulating a fresh framework that assimilates the latest advancements in liquid theory, he demonstrates that melting lines can be outlined by a basic parabolic equation. This not only provides a functional instrument for forecasting melting points but also unveils an astonishing uniformity across diverse material categories. This uniformity emerges from the observation that parameters in the parabolic equation are directed by fundamental physical constants such as the Planck constant and electron mass and charge.

“The simpleness and universality of this finding are particularly stimulating,” explains Professor Trachenko. “It suggests that melting, despite its complexities, shows a basic uniformity across diverse systems, ranging from noble gases to metals.”

This revelation carries significant consequences beyond theoretical physics. Accurate prediction of melting points is critical in materials science, with uses extending from drug formulation to devising advanced materials and other areas where predicting phase diagrams is crucial. The work of Professor Trachenko lays the groundwork for an advanced understanding of phase transitions and the production of new materials with customized properties.
