Theodoor Overbeek
Jan Theodoor Gerard Overbeek (Groningen, January 30, 1911 – February 19, 2007) was a Dutch professor of physical chemistry at the Utrecht University. Early life and education Overbeek was born in Groningen. Overbeek's family moved to Rotterdam in 1913 and to Breda in 1925. Overbeek went to study chemistry (from 1928 to 1933) at the Utrecht University. He spent a year in military service and then worked for two years in Belgium. First year he worked with Jacques Errera at the Université libre de Bruxelles, after that a year with Arend Joan Rutgers at Ghent University. He received his doctorate on May 19, 1941, with a thesis Theory of Electrophoresis, the Relaxation Effect ''(Theorie der electrophorese: het relaxatie-effect)''. All the characteristic features of the later work of Overbeek were present already in his thesis: formation of a simple model with the available data, set up the corresponding equations and then rigorous mathematical elaboration.

Groningen
Groningen (; gos, Grunn or ) is the capital city and main municipality of Groningen province in the Netherlands. The ''capital of the north'', Groningen is the largest place as well as the economic and cultural centre of the northern part of the country; as of December 2021, it had 235,287 inhabitants, making it the sixth largest city/municipality of the Netherlands and the second largest outside the Randstad. Groningen was established more than 950 years ago and gained city rights in 1245. Due to its relatively isolated location from the then successive Dutch centres of power ( Utrecht, The Hague, Brussels), Groningen was historically reliant on itself and nearby regions. As a Hanseatic city, it was part of the North German trade network, but later it mainly became a regional market centre. At the height of its power in the 15th century, Groningen could be considered an independent city-state and it remained autonomous until the French era. Today Groningen is a universi ...

Van Der Waals Force
In molecular physics, the van der Waals force is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The van der Waals force quickly vanishes at longer distances between interacting molecules. Named after Dutch physicist Johannes Diderik van der Waals, the van der Waals force plays a fundamental role in fields as diverse as supramolecular chemistry, structural biology, polymer science, nanotechnology, surface science, and condensed matter physics. It also underlies many properties of organic compounds and molecular solids, including their solubility in polar and non-polar media. If no other force is present, the distance between atoms at which the force becomes repulsive rather than attractive as the atoms approach one another is called the van der Waals contact distance; this phenomen ...

The University of Bristol is a Red brick university, red brick Russell Group research university in Bristol, England. It received its royal charter in 1909, although it can trace its roots to a Society of Merchant Venturers, Merchant Venturers' school founded in 1595 and University College, Bristol, which had been in existence since 1876.

Clarkson University
Clarkson University is a private research university with its main campus in Potsdam, New York, and additional graduate program and research facilities in the New York Capital Region and Beacon, New York. It was founded in 1896 and has an enrollment of about 4,300 students studying toward bachelor's, master's, and doctoral degrees in each of its schools or institutes: the Institute for a Sustainable Environment, the School of Arts & Sciences, the David D. Reh School of Business, the Wallace H. Coulter School of Engineering, and the Earl R. and Barbara D. Lewis School of Health Sciences. It is classified among "R2: Doctoral Universities – High research activity." History The school was founded in 1896, funded by the sisters of Thomas S. Clarkson, a local entrepreneur who was accidentally killed while working in his sandstone quarry not far from Potsdam. When a worker was in danger of being crushed by a loose pump, Clarkson pushed him out of the way risking his own life. Cla ...

Macroemulsion
Macroemulsions are dispersed liquid-liquid, thermodynamically unstable systems with particle sizes ranging from 1 to 100 μm (orders of magnitude), which, most often, do not form spontaneously. Macroemulsions scatter light effectively and therefore appear milky, because their droplets are greater than a wavelength of light. They are part of a larger family of emulsions along with miniemulsions (or nanoemulsions). As with all emulsions, one phase serves as the dispersing agent. It is often called the continuous or outer phase. The remaining phase(s) are disperse or inner phase(s), because the liquid droplets are finely distributed amongst the larger continuous phase droplets. This type of emulsion is thermodynamically unstable, but can be stabilized for a period of time with applications of kinetic energy. Surfactants (as the main emulsifiers) are used to reduce the interfacial tension between the two phases, and induce macroemulsion stability for a useful amount of time. Emulsion ...
