Jan van Deemter. Jan Jozef van Deemter (31 March 1918 – 10 October 2004) was a Dutch physicist and engineer known for the Van Deemter equation in chromatography.

He obtained his doctorate in physics from the University of Amsterdam in June of 1950. Starting in 1947 he began work for Royal Dutch Shell as a researcher and it was there that he developed and published his article in 1956.

Van Deemter equation
The van Deemter equation relates the resolving power of a chromatographic column to the various flow and kinetic parameters which cause peak broadening through

Where HETP is the height equivalent theoretical plate, A is the eddy-diffusion parameter, B is the longitudinal diffusion coefficient of the eluting material in the longitudinal direction, C is the resistance to mass transfer coefficient of the analyte between mobile and stationary phase, and u is the linear velocity of the column flow.

Mircea Dincă. Mircea Dincă (born 1980) is a Romanian-American inorganic chemist. He is the Andrew Stewart 1886 Professor of Chemistry at Princeton University. At Princeton, Dincă leads a research group that focuses on the synthesis of functional metal-organic frameworks (MOFs), which possess conductive, catalytic, and other material-favorable properties.

Early life and education
Mircea Dincă was born in Făgăraș, Romania. His passion for chemistry began in his chemistry class in 7th grade, where he had a "dedicated teacher that did spectacular demonstrations with relatively limited regard for safety". In 1998, he represented Romania at the International Science Olympiad (Chemistry) in Yakutsk, Russia, where he won first prize.

After high school, Dincă was offered a scholarship from Princeton University and moved to New Jersey in 1999. At Princeton, he worked with Jeffrey Schwartz, conducting research on materials science. After graduating magna cum laude in 2003, Dincă went on to the University of California, Berkeley to attend the Chemistry doctorate program, where he worked with chemistry professor Jeffrey R. Long on increasing H2 adsorption in metal-organic frameworks with mobile hydrogen storage applications. He graduated with his Ph.D. from Berkeley in 2008.

Career 
Dincă completed his postdoc studies at MIT, where he was promoted to associate professor in 2010 and, in 2017, tenured. Until 2024, he was the W. M. Keck Professor of Chemistry. In 2025, he joined the faculty at Princeton University.

Research 
Dincă's research primarily focuses on electrical conductivity of MOF's, which was previously unknown and resulted in a new categorization of such materials with "charge mobility values". His focus is on the exploration of increasing electrical conductivity capacities through the marriage of organic and inorganic materials to assemble hybrid MOF's.

Research includes exploring electrochemical cycling through strongly adhering, electroactive metal–organic framework thin films to vary results, such as multicolored electrochromic responses and transparent to dark behavior.

Auguste Rateau. Auguste Rateau (; 13 October 1863 – 13 January 1930) was an engineer and industrialist born in Royan, France, specializing in turbines.

Biography
After studies, first at the École Polytechnique and then at the École des Mines de Paris, he began his career as a teacher at the École des Mines de Saint-Étienne from 1888 to 1897.

He then embarked on an industrial career exploiting turbines. He manufactured fans for mines, blowers for steel mills, water pumps, and steam turbines for ships. To this end, he created a design office in Paris and, in 1903, the Société pour l’exploitation des appareils Rateau, which moved in 1917 to La Courneuve where he opened a factory two years later. The company has since been integrated into Alstom, and La Courneuve's premises are still operated by GE Power Service. This entity manages the maintenance of turbomachines, turbo-pumps and turbocompressors installed on nuclear, thermal and industrial sites in France and in some parts of the world.

In 1928 he founded the Association Française de Normalisation, the French national organization for standardization, and served as president.

Rateau was a Commander of the Legion of Honour () and a member of the French Academy of Sciences ().

Messaging Layer Security. Messaging Layer Security (MLS) is a security layer for end-to-end encrypting messages. It is maintained by the MLS working group of the Internet Engineering Task Force, and is designed to provide an efficient and practical security mechanism for groups as large as 50,000 and for those who access chat systems from multiple devices.

Security properties
Security properties of MLS include message confidentiality, message integrity and authentication, membership authentication, asynchronicity, forward secrecy, post-compromise security, and scalability.

History
The idea was born in 2016 and first discussed in an unofficial meeting during IETF 96 in Berlin with attendees from Wire, Mozilla and Cisco.

Initial ideas were based on pairwise encryption for secure 1:1 and group communication. In 2017, an academic paper introducing Asynchronous Ratcheting Trees was published by the University of Oxford and Facebook setting the focus on more efficient encryption schemes.

The first BoF took place in February 2018 at IETF 101 in London. The founding members are Mozilla, Facebook, Wire, Google, Twitter, University of Oxford, and INRIA.

As of March 29, 2023, the IETF has approved publication of Messaging Layer Security (MLS) as a new standard. It was officially published on July 19, 2023. At that time, Google announced it intended to add MLS to the end to end encryption used by Google Messages over RCS.

Matrix is one of the protocols declaring migration to MLS.

Research on adding post-quantum cryptography (PQC) to MLS is ongoing, but MLS does not currently support PQC.

Martin Road Bridge. The Martin Road Bridge (also known as the Snuff Mill Bridge or Snuff Mill Road Bridge) is a former road bridge which carried Martin Road across the Shiawassee River in Caledonia Township near Corunna. It was one of the oldest metal through truss highway bridges in Michigan, and was listed on the National Register of Historic Places in 1991. As of 2016, the bridge has been removed from its original site, and will be restored and reassembled at the Auburn Valley State Park in Yorklyn, Delaware.

History
In about 1850, settler Titus Yerkes dammed the river near this point and constructed a mill. A second mill was constructed later in the nineteenth century, and this location became an important local milling center. It is not known when the first Martin Road bridge was constructed, but there was one in place by 1874. This bridge was apparently washed out in the 1880s, and in 1885, Caledonia Township contracted with the Mount Vernon Bridge Company of Mount Vernon, Ohio to design and construct a replacement bridge. The company installed this bridge at the site. It is the only known example of this firm's highway bridge work known to survive in Michigan. Although the bridge was in use for years, the mills that made this river crossing locally important were gone by 1908.

However, the bridge eventually deteriorated, and it was closed to traffic in 1987. In 2015, the township sold the Auburn Valley State Park in Yorklyn, Delaware. In 2016, the bridge was disassembled and removed by Bach Steel. Renovation is underway. As of 2021, the Park's master plan envisioned the bridge (rechristened the "Snuff Mill Road Bridge") being widened and used as part of a recreational trail.

Description
The Martin Road Bridge is a single-span, metal, pin-connected, Pratt through truss structure having. The bridge is 119 feet long and fifteen feet wide between the trusses. The deck is made up of three-by-eight-inch wooden planks, supported by six rows of six-inch I-beams and two rows of six-inch channels, all supported by sixteen-inch metal floor beams. In its original location, rubble fieldstone abutments on each bank supported the bridge. A plaque mounted on one end post names the bridge's builder, the Mt. Vernon Bridge Company of Mt. Vernon, Ohio, and the 1885 year of construction.
