Frank E. Rom. Frank Ernest Rom Sr. was an engineer who worked for the National Advisory Committee for Aeronautics (NACA) and it successor, the National Air and Space Administration (NASA). He wrote many papers on the uses of nuclear propulsion for rockets for interplanetary travel. In the 1970s, he was involved in NASA's exploration of solar, wind and tidal energy sources as alternative to fossil fuels, and found his own solar energy company, Rom-Aire Solar Energy Products, based on his patents for air-based solar heating and collecting systems.

Early life
Frank Ernest Rom Sr. was born in Brooklyn, New York on August 16, 1926, the son of Frank and Josefa Rom, a pair of immigrants from Austria. He was educated in public schools in New York City, and attended Cooper Union there. During World War II, he served in the US Navy. After the war he entered Cornell University, from which he graduated both bachelor's and master's degrees.

NASA 

In 1948, Rom joined the National Advisory Committee for Aeronautics (NACA) Lewis Research Center in Cleveland, Ohio, where he met his future wife, Marilyn McNamara. They had seven children. His early work there was on the development of long-range aircraft, powered by jet engines and turboprop engines. He then became involved in the Aircraft Nuclear Propulsion project. He was one of the first to consider the possibility of a nuclear-powered ramjet missile, writing a paper on it in 1954. He became an important figure in the development of NASA's Plum Brook Reactor facility in Sandusky, Ohio.

Rom studied the use of nuclear propulsion systems for crewed interplanetary rockets, becoming the chief of the Nuclear Propulsion Concepts Branch at Lewis, and assisted the Los Alamos Scientific Laboratory with Project Rover, its development of a nuclear rocket engine. His work covered all aspects of nuclear propulsion from fissile materials to nuclear reactor design and nuclear waste.  and was Lewis's point of contact  for its  materials, fuel element research, and hydrogen heat transfer technologies. He produced many papers on nuclear rockets., and was the first to the propose the design, and demonstrate the feasibility, of a tungsten-based gas-core nuclear reactor, a type that would be especially suitable for interplanetary exploratory missions, such as a mission to Mars. He also proposed the development of a nuclear-powered hovercraft.

Solar energy 
After the nuclear rocket design work at Lewis dried up, Rom became involved in  NASA's exploration of solar, wind and tidal energy sources as alternative to fossil fuels, and found his own solar energy company, Rom-Aire Solar Energy Products, based on his patents for air-based solar heating and collecting systems.

Death 
Rom died in Venice, Florida, on November 4, 2012, and was interred in the Memorial Rose Garden of the Epiphany Cathedral in Venice, where he was an active member.

Eriksberg Crane. The Eriksberg Crane () is a full gantry crane in the Eriksberg district of Gothenburg, part of the former Eriksberg shipyard. It is a listed building, and is considered to be one of the city's main landmarks and an important relic of its industrial and maritime heritage.

The company Eriksbergs Mekaniska Verkstad was founded in the Eriksberg district of Gothenburg in 1876, and initially specialised in manufacturing iron and steel parts, but later switched its focus to shipbuilding and built up a sizeable shipyard on the north bank of the Göta Älv, on the island of Hisingen.

The main structure of the crane was fashioned in eight sections by NOHAB in Trollhättan in 1968, and was transported by barge down the Göta Älv to Gothenburg. The crane was assembled and erected at one of the dry docks in the Eriksberg shipyard in 1969. The lifting gear was manufactured by Pohlig-Heckel-Bleichert (PHB) in Cologne.

However, in the event the new gantry crane only saw a decade of use. Eriksbergs Mekaniska Verkstad was bought out by the Swedish state in 1975, becoming part of the nationalised Svenska Varv, and production at the Gothenburg shipyard was wound down in 1978–1979, with the yard's final vessel, the M/T Atland, being delivered on 15 June 1979.

From 1993 the crane has been used for bungee jumping, and at 84 metres in height, it is Sweden's highest bungee-jumping location.

It was recognised as a listed building in 2012.

Although no longer operational, the Eriksberg Crane is the only remaining full gantry crane in Sweden. There were once similar cranes at shipyards in Uddevalla and Malmö, but the former was scrapped in 1986 and the latter (the so-called Kockums Crane) was sold to Hyundai Heavy Industries in 2002, for the nominal sum of $1 (USD), and transported to Ulsan in South Korea.

Moldable wood. Moldable wood is a strong and flexible cellulose-based material. Moldable wood can be folded into different shapes without breaking or snapping. The patented synthesis is based on the deconstruction and softening of the wood's lignin, then re-swelling the material in a rapid "water-shock" process that produces a wrinkled cell wall structure. The result of this unique structure is a flexible wood material that can be molded or folded, with the final shape locked in plate by simple air-drying. This discovery broadens the potential applications of wood as a sustainable structural material. This research, which was a collaborative effort between the University of Maryland, Yale University, Ohio State University, USDA Forest Service, University of Bristol, University of North Texas, ETH Zurich, and the Center for Materials Innovation, was published on the cover of Science in October 2021.

Nyamwamba II Hydroelectric Power Station. Nyamwamba II Hydroelectric Power Station, is a 7.8 megawatts mini-hydroelectric power station, that was commercially commissioned in March 2022 in Uganda. The run of river mini-hydroelectric installation is owned and was developed, between October 2019 and March 2022, by Serengeti Energy Limited, a Kenyan independent power producer (IPP), which was formerly called responsAbility Renewable Energy Holding (rAREH). The energy generated here is sold directly to the Ugandan electricity transmission parastatal company, Uganda Electricity Transmission Company Limited (UETCL), under a 20-year power purchase agreement (PPA). The power is integrated into the Ugandan national electric grid.

Location
The power station is located in the village of Kilembe, across the River Nyamwamba, in Kasese District in the Western Region of Uganda. This is in the foothills of the Rwenzori Mountains, close to the border with the Democratic Republic of the Congo. Nyamwamba II HPP straddles the Nyamwamba River, upstream of the 9.2 megawatts Nyamwamba I Hydroelectric Power Station, also owned an operated by Serengeti Energy Limited.

Overview
The power station is a run of the river mini-hydropower installation, with installed capacity of 7.8 megawatts. The power station is owned by Serengeti Energy Limited, an IPP based in Nairobi, Kenya.

The engineering, procurement and construction (EPC) contractor for Nyamwamba II HPP was a consortium comprising South Asia Energy Management Systems LLC (SAEMS), based in Sri Lanka, who were responsible for civil works, and Andritz AG of Austria, who were responsible supplying and installing the electric generators and other electromechanical installations. Zutari Engineering, based in South Arica, was the Owner's Engineer.

Construction costs and funding 
The construction costs are reported to be US$22 million. The table below illustrates the sources of funding for this renewable energy project.

In May 2022, Afrik21.africa reported that Emerging Africa Infrastructure Fund (EAIF), lent Serengeti Energy US$10.6 million, to be repaid over 17 years. As a result of that loan, Serengeti was able to retire the construction loans, leaving EAIF as the sole lender to the project.

Construction timetable
Construction started in October 2019 and commercial commissioning was effected on 17 March 2022.

Other considerations
Nyamwamba II HPP created 205 jobs during the construction phase and employs 25 people during the operational phase. It provides electricity to an estimated 161,000 Ugandan customers. The green energy it produces helps reduce carbon dioxide emissions by 18,000 tonnes annually.

Francesco Sciortino. Francesco Sciortino (born December 29, 1960) is an Italian physicist and full professor at Sapienza University of Rome. He has made seminal contributions to statistical physics, including the thermodynamic and dynamic theory of complex fluids like water, colloids, colloidal-polymer mixtures, patchy particles, and DNA-based materials. He is one of the original proponents of the "second liquid critical point" theory of water.

Education

Sciortino was awarded a Ph.D. in physics from the University of Palermo in 1989 working on the coupling between biomolecules and the solvent, and focusing on the role of water's hydrogen bond cooperativity in supramolecular arrangement of biomolecules. After the Ph.D., Sciortino became research assistant in the Center for Polymer Studies of Boston University, working in the group of Prof. H. Eugene Stanley.

Academic career

Following his postdoctoral research position in Boston, in 1992 Sciortino became a researcher in Centro di Ricerca, Sviluppo e Studi Superiori in Sardegna, Cagliari. One year later he moved to Sapienza University of Rome, where he became assistant professor in 1993, associate professor in 2000, and full professor in 2005. He serves as associate editor of the Journal of Chemical Physics.

Research and achievements

Sciortino has made seminal contributions in the field of statistical mechanics and soft condensed matter theory. He is one of the original proponents of the Second Liquid Critical Point Hypothesis for water,. which explains water's anomalous behaviour with the presence of a hidden critical point in supercooled water. Experimental verification of this hypothesis has been obtained numerically in several models of water, and finally confirmed with scattering experiments using X-ray pulses.

Sciortino has worked extensively on the physics of arrested states of matter, making seminal contribution to Mode Coupling theory and the Potential Energy Landscape formalism. He and his collaborators hypothesised a novel type of glass (re-entrant glass) in short-range attractive colloidal systems, and this prediction was later confirmed by several experiments and numerical simulations.
Sciortino and his co-authors were also the first to identify colloidal gels as the outcome of a dynamical arrested phase separation process. His contributions to the physics of reduced valence interactions are numerous: the discovery of empty liquids, equilibrium gels, re-entrant topological transitions in network fluids, among many others

According to Scopus, Sciortino's work has been cited 27315 times, and his H-index is 93. Google Scholar lists 38415 citations and an H-index of 105 . Thanks to these bibliometric indexes, he is ranked among the top 10 Italian Physicists in activity.

Deborah F. Kelly. Deborah F. Kelly is an American biomedical engineer who is a professor at Pennsylvania State University. Her research makes use of cryogenic electron microscopy to better understand human development and disease. She was elected President of the Microscopy Society of America in 2022. 
 Some of her papers have been retracted, and Pennsylvania State University barred her from conducting research for the institution due to what its investigation determined were data integrity problems in her work.

Early life and education 
Kelly attended Florida State University for graduate research. She moved to the Harvard Medical School for her postdoctoral research. After seven years as a research fellow at Harvard, Kelly joined the Virginia Tech School of Medicine as an assistant professor.

Research and career 
In 2017, Kelly was promoted to associate professor at Virginia Tech. She moved to Pennsylvania State University as Director of the Center for Structural Oncology in 2019.

Kelly combines structural and functional characterization tools to understand cellular communication. Amongst these, she has considered protein receptors. On the surfaces of cells, these receptors transmit information about cellular microenvironment to cellular nuclei. These signals can cause genes to turn off and on. Cancer cells can thrive when genes are activated inappropriately during cell division. These cancerous cells can evade conventional forms of treatment and are understood to result in the formation of malignant tumors. By determining the three-dimensional structure of these protein complexes Kelly hopes to design new therapeutic interventions.

Kelly makes use of cryogenic electron microscopy to visualize these cellular interactions. Specifically, she has developed a platform ('affinity capture') that can isolate the cells which cause metastasis. Kelly developed a microchip toolkit to identify mutations in BRCA1. These microchips, which she called cryo-chips, use silicon nitride to quickly identify, isolate and tether protein assemblies. When the COVID-19 pandemic started, Kelly shifted her focus to the SARS-CoV-2 virus. However, one study by Kelly and colleagues, studying the N protein of SARS-CoV-2 and using the group's chip technology, was later retracted by Nanoscale due to several technical problems and questions.

Kelly has also reported methods which propose to determine protein structures in the liquid phase (Liquid-EM), as opposed to the standard frozen state of Cryogenic electron microscopy. However, the validity of this method and the reported results have been questioned by others in the field. Four of her papers have been retracted, she has been banned from research activities at Pennsylvania State University (following an investigation by the university that found "serious data integrity concerns"), and her work continues to be scrutinized.

John Raphael Rogers. John Raphael Rogers (c. 1857 - February 18, 1934) invented the Typograph, a form of typesetting machine.  The patent for setting a line of type in a single bar of metal was held by the Linotype company, so Rogers was unable to market his invention in the US. He sold the patent to a German company, and it was used successfully in Germany for some years.

He was born in Roseville, Illinois, to John A. Rogers and Elizabeth Embree Rogers.  He graduated from Oberlin College with a bachelor's degree in 1875.  He worked as a school teacher and school superintendent until 1886, after which he worked on his inventions full time.  He received a patent for the Rogers Typograph in 1888.

1,6-Hexanediol diglycidyl ether. 1,6-Hexanediol diglycidyl ether is an organic chemical in the glycidyl ether family. It is an aliphatic compound that is a colorless liquid. It has two epoxide (oxirane) groups per molecule. Its main use is in modifying epoxy resins especially viscosity reduction whilst flexibilizing. It is REACH registered.

Manufacture
1,6-Hexanediol and epichlorohydrin are reacted in the presence of a Lewis acid as catalyst to form a halohydrin: each hydroxyl group of the diol reacts with an epoxide on epichlorohydrin. This process is followed by washing with sodium hydroxide to re-form the epoxide rings in a dehydrochlorination reaction. One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.

Uses
Its main use is for reduction of viscosity in epoxy resin systems - it is thus an epoxy reactive diluent. The chain length helps give some degree of flexibility as an epoxy resin has rigid aromatic rings which are planar. These systems may then be formulated into CASE applications: Coatings,  Adhesives, Sealants, Elastomers, and composite materials. The use of the diluent does effect mechanical properties and microstructure of epoxy resins.

Toxicity
The toxicity is fairly well understood. It is classed as a skin irritant, skin sensitizer, allergen and has caused contact dermatitis.
