Chemical transformation via disruptive innovation in laboratory settings

Chemical transformation via disruptive innovation in laboratory settings

In the realm of chemistry, one concept that has stood the test of time is the Parachor. Originally introduced in the early 20th century by Sugden and Quayle, Parachor is an empirical parameter that links surface tension to molecular volume and composition[1].

Over the years, Parachor has evolved from a purely empirical tool to one embedded within more sophisticated models of interfacial phenomena and materials characterization[2]. It is still used, particularly in polymer and surface chemistry fields, for estimating surface tension and interfacial properties based on composition and temperature[3].

However, modern chemical research increasingly integrates Parachor concepts within molecular simulations and thermodynamic models that account for molecular interactions explicitly[3]. This shift reflects the broader trend in chemistry towards a more mechanistic molecular understanding and model integration.

Recent publications from 2025 show Parachor's active application and refinement rather than obsolescence[2], aligning with its role as a bridging concept between classical thermodynamics and modern materials chemistry. No evidence suggests that Parachor has been fully discarded; instead, its conceptual use and quantitative methods based on it are evolving to remain relevant in contemporary research[4].

Meanwhile, in the lab, the location of KBr discs and the IR machine, once common tools in chemistry, is unknown. Improvements in automation and data handling are expected to play a significant role in the future of high-throughput experimentation, gradually decreasing the importance of traditional methods like high-throughput screening[5].

Some old technologies may still be found in odd niches or be repurposed entirely in the future. For instance, while mechanical adding machines and analytical balances with clattering, weight-shifting knobs have been replaced, pipettes persist in some form or another[6].

Negative data that has been swept under the carpet for the last century will also be utilized in the future, as the way chemists deal with literature and retrosynthesis is expected to bring more machine-learnable order[7].

It is not expected that we will be blithely designing final drug candidates using artificial intelligence/machine learning in the near future, but computational methods will likely provide workable starting points for lead optimisation in drug discovery[8]. High-throughput experimentation in reaction optimisation is expected to become more common, gradually replacing traditional methods[9].

In conclusion, while some old technologies may fade away, the spirit of innovation and the pursuit of knowledge continue to drive the field of chemistry forward. The Parachor, despite being considered outdated in some circles, remains a testament to the evolution of chemical concepts and the importance of bridging the gap between classical and modern approaches.

Organic chemistry, a discipline within the vast field of science, employs Parachor, an empirical parameter originating in the early 20th century, to estimate surface tension and interfacial properties based on composition and temperature, particularly in polymer and surface chemistry.

Moreover, technology, in the form of molecular simulations and thermodynamic models, now accounts for molecular interactions explicitly in the application of Parachor, reflecting the broader trend in chemistry towards a more mechanistic molecular understanding and model integration.
