The following article is based on this paper.

From the airflow over a jet wing to the complex weather patterns of a hurricane, our world is governed by powerful mathematical rules. Scientists call these rules differential equations. For centuries, solving these equations has been the key to unlocking breakthroughs in science and engineering.

The problem is, most of these equations are far too complex to solve with a pen and paper. For decades, we've relied on massive supercomputers to get "close-e...

Fundamental investigations of ice nucleation, a key process in fields from environmental science to cryobiology, require model systems with chemical and physical structures that are well defined and easily varied. DNA origami is an especially promising model because of the exquisite control that it offers over the physical geometry of the nucleating agent at the nano-scale. Here we compare ice nucleation by solutions of a rectangular ...

Imagine pouring a thick smoothie through a straw—smooth and steady at first, but crank up the speed, and suddenly it's a messy splatter. That's basically what happens in pipes carrying fluids mixed with particles, like blood flowing with cells or oil slurping up sand. In the world of fluid dynamics, this shift from calm "laminar" flow to wild "turbulent" flow is a big deal. It affects everything from how efficiently we transport oil to understanding diseases in our veins. But spotting that flip—...

Poincaré Conjecture In its original form, the Poincaré conjecture states that every simply connected closed three-manifold is homeomorphic to the three-sphere (in a topologist's sense), where a three-sphere is simply a generalization of the usual sphere to one dimension higher. In layman terms, the conjecture says that the three-sphere is the only type of bounded three-dimensional space possible that contains no holes. It…

Did you know? The human nose can detect over 1 trillion scents—far beyond the old myth of just 10,000. A 2014 Rockefeller University study upended that limit using complex odor mixtures on volunteers. 🤯👃 #ScienceFacts

Two-dimensional quantum material heterostructures are emerging as a strong option for creating energy-efficient, non-volatile spin-based devices. In these systems, researchers have observed tunable and unusual spin orbit torque behaviors when 2D materials with engineered electronic and magnetic properties are combined. Recent breakthroughs using van der Waals heterostructures—particularly those made from the Weyl semimetal TaIrTe₄ and out-of-plan...

Chromium ditelluride, CrTe2, is an attractive candidate van der Waals material for hosting 2D magnetism. However, how the room-temperature ferromagnetism of the bulk evolves as the sample is thinned to the single-layer limit has proved controversial. This, in part, reflects its metastable nature, vs. a series of more stable self-intercalation compounds with higher relative Cr:Te stoichiometry. Here, exploiting a recently develo...

Here is a summary of my recent research conducted at the Research Centre for Fluid and Complex Systems at Coventry University:

Figure 1 shows that salinity reduction significantly decreases the activity coefficients calculated by both the extended Debye-Huckel and Pitzer activity models. This reduction causes noticeably lower concentration estimates for most ions, except for SiO2 (aq) and Ca2+, with reductions ranging from approximately 20% to 100% (see Figure 2). Furthermore, Figure 2 indicates...
