Small stationary reformer. A small stationary reformer is an on-site device used for the production of hydrogen from hydrocarbons on a small scale.

Types

Plate-type steam methane reformers

Multi-tube steam reformer

Membrane reactor
A membrane reactor is a device where oxygen separation, steam reforming and POX is combined in a single step. In 1997 Argonne National Laboratory and  Amoco published a paper "Ceramic membrane reactor for converting methane to syngas" which resulted in different small scale systems that combined an ATR based oxygen membrane with a water-gas shift reactor and a hydrogen membrane.

POX reactor
Partial oxidation (POX) is a type of chemical reaction. It occurs when a substoichiometric fuel-air mixture is partially combusted in a reformer, creating a hydrogen-rich syngas which can then be put to further use, for example in a fuel cell. A distinction is made between thermal partial oxidation (TPOX) and catalytic partial oxidation (CPOX).

Centralized hydrogen production
The capital cost of methane reformer plants is prohibitive for small to medium size applications because the technology does not scale down well. Conventional steam reforming plants operate at pressures between 200 and 600 psi with outlet temperatures in the range of 815 to 925 °C. However, analyses have shown that even though it is more costly to construct, a well-designed SMR can produce hydrogen more cost-effectively than an ATR. To lower the costs both pressure and used temperature are lowered which allows for the use of cheaper materials.

Sa'ar 72-class corvette. The Sa'ar 72 () is a class of Israeli Navy corvettes designed by Israel Shipyards Ltd. as an improved and stretched .  The first Sa'ar 72 was expected to become operational in 2015 but the process to begin construction was not approved until 2024. Subsequent vessels were planned to enter service at the rate of one every eight months.

History
The design was first unveiled at the International Maritime Defence Exhibition (IMDEX) Asia in Singapore in May 2013.

On December 12, 2024, the Director General of the Israel Ministry of Defense (IMOD), Maj. Gen. (Res.) Eyal Zamir, publicly announced a procurement agreement from Israel Shipyards for five Sa'ar 72 type boats, dubbed "Reshef" in Hebrew, with a total value of approximately $780M (NIS 2.8B). This comes following a legislative committee approval to fund procurement of these vessels, among other military equipment.

2-Nitrotoluene. 2-Nitrotoluene or ortho-nitrotoluene is an organic compound with the formula CH3C6H4NO2.  It is pale yellow liquid that crystallizes in two forms, called α (−9.27 °C) and β (−3.17 °C).  It is mainly a precursor to o-toluidine, which is an intermediate in the production of various dyes.

Synthesis and reactions
It is made by nitrating toluene at above -10 °C.  This reaction affords a 2:1 mixture of 2-nitro and 4-nitro isomers.

Chlorination of 2-nitrotoluene gives two isomers of the chloronitrotoluenes.  Similarly nitration gives two isomers of dinitrotoluene.

2-Nitrotoluene is mainly consumed in the production of o-toluidine, a precursor to dyes.

Aeroflot Flight 6502. Aeroflot Flight 6502 was a Soviet domestic passenger flight operated by a Tupolev Tu-134A from Sverdlovsk (now Yekaterinburg) to Grozny via Kuibyshev (now Samara), which crashed in Kuibyshev on 20 October 1986. Seventy of the 94 passengers and crew on board were killed when the plane overran the runway, after the pilot made a bet that he could make an instrument-only approach with curtained cockpit windows. Investigators determined the cause of the accident was pilot negligence.

Background
The crew of the Tu-134A aircraft, serial number 62327 manufactured on 28 June 1979, consisted of pilot in command Alexander Kliuyev, co-pilot Gennady Zhirnov, navigating officer Ivan Mokhonko, flight engineer Kyuri Khamzatov, and three flight attendants. Having departed from Koltsovo Airport in Yekaterinburg (then Sverdlovsk) and bound for Grozny, Flight 6502 had one stopover at Kurumoch Airport in Samara (then Kuibyshev).

Crash
While approaching Kurumoch Airport, Captain Kliuyev made a bet with First Officer Zhirnov that he could make an instrument-only approach with curtained cockpit windows, thus having no visual contact with the ground, instead of an NDB approach, suggested by the air traffic control. Kliuyev further ignored the ground-proximity warning at an altitude of  and did not make the suggested go-around. The aircraft touched down on the runway at a speed of  and came to rest upside down after overrunning the runway. Sixty-three people died during the accident and seven more in hospitals later. Among the passengers were 14 children, all of whom survived the accident. The top-secret report of the chairman of Kuibyshev oblispolkom V. A. Pogodin to  Premier Nikolai Ryzhkov gave slightly different figures: Of 85 passengers and eight crew members aboard, 53 passengers and five crew members died in the crash and 11 more in hospitals later.

Though Zhirnov made no attempt to avert the crash, he subsequently tried to save the passengers and died of cardiac arrest while on the way to the hospital. Kliuyev was prosecuted and sentenced to 15 years in prison, later reduced to six years served.

Andreas Hierlemann. Andreas Hierlemann (17 August 1964) is a German chemist and professor of Biosystems Engineering at ETH Zurich. He is known for his work in the field of CMOS-based chemical and biomicrosensors and high-density microelectrode arrays.

Life
From 1985 to 1991, Hierlemann studied chemistry at the University of Tübingen, Germany. He received a PhD from the University of Tübingen in 1996 for his work on Mass-sensitive detection of organic volatiles using modified polysiloxanes. 1997–98 he held postdoctoral positions at Texas A&M University in College Station, Texas, USA, and at Sandia National Laboratories in Albuquerque, New Mexico, USA. From 1999 to 2004 he was research team leader at the Physical Electronics Laboratory in the Department of Physics of ETH Zürich, Switzerland, becoming associate professor for microsensors in 2004. In 2008 he was named full professor of Biosystems Engineering, Department of Biosystems Science and Engineering of ETH Zurich in Basel, Switzerland.

Scientific contribution
Hierlemann's research initially was mostly in the area of chemical sensors and microsensors. In particular, he worked on the detection of organic volatiles and the discrimination of enantiomers in the gas phase. He then adopted microtechnology and, specifically, CMOS-based microelectronics to devise complex microsensor systems. The current interdisciplinary research is rooted in engineering and physics and targeted at questions in biology and medicine. It includes the development of CMOS-based integrated chemical and biomicrosystems, as well as bioelectronics and high-density microelectrode arrays. The high-density microelectrode arrays are used for fundamental research in information processing and signaling characteristics of neurons or brain cells. Moreover, the research group is engaged in the development of microfluidics for investigating the characteristics of single cells and microtissues.

Applications of Hierlemann's and his group's technologies are in the fields of systems biology, drug testing, personalized medicine, and neuroscience.
