1,1,1-Tris(aminomethyl)ethane. 1,1,1-Tris(aminomethyl)ethane (TAME) is an organic compound with the formula CHC(CHNH). It is a colorless liquid.  It is classified as a polyamine tripodal ligand, i.e., capable of binding to metal ions through three sites and hence is a tridentate chelating ligand, occupying a face of the coordination polyhedron.

Preparation
TAME is synthesized by the Pd/C-catalyzed hydrogenation of 1,1,1-tris(azidomethyl)ethane. Although azides are potentially explosive, they are excellent and practical source of primary amines. The required tris(azidomethyl)ethane is obtained from the tritosylate by salt metathesis using sodium azide.  These two steps are:

3 NaN  +  CHC(CHOTs)   →   CHC(CHN)  +  3 NaOTs 
3 H  +  CHC(CHN)   →   CHC(CHNH)  +  3 N

Complexes of TAME
The tripodal TAME ligand coordinates facially to metal ions. This stereochemical feature has been exploited in the preparation of platinum(IV) cage complexes, e.g., [Pt(tame)], which is a six coordinate Pt(IV) complex. Platinum in its +4 oxidation state has a d configuration and is kinetically inert. For this reason the formation of [Pt(tame)] is initiated by installing TAME on a platinum(II) precursor.  The resulting square planar complex is oxidized with [PtCl] to produce the target Pt(IV) derivatives.

Adventure Aircraft EMG-6. The Adventure Aircraft EMG-6, (Electric Motor Glider Model 6), is a proposed one or two-seat electric airplane designed to be reconfigurable for operation as either a glider or a powered motor glider.

Design and development
The EMG-6 began development in March 2013 from the lessons learned on the EMG-5 after the FAA's response to the manufacturer's (then Tangent Aircraft; now Adventure Aircraft) request for clarification on battery weight and the maximum ultralight empty weight specified in FAR 103.  The EMG-6 was announced at a press conference during Airventure 2013.

The EMG-6 seats up to two occupants in tandem, has folding wings, and is designed to be operated either as a glider or as an electric motor glider with propulsion options of either two wing-mounted tractor configuration motor/propeller units or two wing-mounted tractor motor/propeller units and a third fuselage mounted pusher motor/propeller unit.  The EMG-6 also incorporates a ballistic parachute and provisions for being towed aloft by a tow plane.  Initial flight testing in late 2013/early 2014 has used a four-wheeler and different types of automobile to tow the glider aloft. A Polini 250cc two-stroke internal combustion engine prototype was also tested.

In April 2013, Adventure Aircraft (then Tangent Aircraft) announced, "We have entered into an agreement with Quicksilver Manufacturing to build the first prototype aircraft jointly. ... Quicksilver is a powerhouse aircraft manufacturing facility that if partnered with our companies have the potential to create a team that can be manufacturing aircraft in the many hundreds even within the next two years." This partnership has since dissolved.

The Rainbow Aviation website contains information on the EMG-6, including downloadable construction drawings, but no updates since late 2019.

Print reading. Print reading, in the manufacturing industry, is the most efficient way to convey information about systems and equipment from the drafting table that could not be conveyed by words alone. By using symbols and notes, a large amount of information that might require many pages of written description can be presented in a condensed form on one diagram.

Since there are many different types of print, using just one diagram with all the information available for that equipment on the same page would be cluttered and ultimately useless. For this reason, the different types of prints evolved. They make the information that the specific type of print is meant to convey clear and uncluttered.

Out-of-kilter algorithm. The out-of-kilter algorithm is an algorithm that computes the solution to the minimum-cost flow problem in a flow network. It was published in 1961 by D. R. Fulkerson and is described here.  The analog of steady state flow in a network of nodes and arcs may describe a variety of processes.  Examples include transportation systems & personnel assignment actions.  Arcs generally have cost & capacity parameters.  A recurring problem is trying to determine the minimum cost route between two points in a capacitated network.  The idea of the algorithm is to identify out-of-kilter arcs and modify the flow network until all arcs are in-kilter and a minimum cost flow has been reached.  The algorithm can be used to minimize the total cost of a constrained flow in an oriented network.

Algorithm 
To begin, the algorithm takes a single cycle and a set of node numbers. It then searches for out-of-kilter arcs. If none are found the algorithm is complete. If the flow needs to be increased or decreased to bring an arc into kilter, the algorithm will look for a path that increases or decreases the flow respectively. If no paths are found to improve the system then there is no feasible flow. This is done until all arcs are in-kilter, at which point the algorithm is complete.

Suppose that the network has n nodes and m oriented arcs.  We write  if arc  has initial node  and terminal node .  Let  be the flow along arc  (from node  to node ).  Define  and  to be the lower and upper capacity bounds on the flow in arc .  The capacities may be either finite, or infinite on some or all arcs for either the lower or upper bounds.  The problem that is at hand to solve is to minimize:  subject to:

 for each  (1)

, and:

 for each  (2)

If a given flow x satisfies (1), then the flow is conserved at each node and we call the flow a circulation.  If the flow x satisfies (2) we say it is feasible.

 The algorithm terminates within  iterations
 Dominant computation is shortest path computation

Silicyne. Silicynes are allotropes of silicon.

1-dimensional silicyne is analogous to the carbon allotrope carbyne, being a long chain of silicons, instead of carbons. It is amorphous silicon with sp hybridization of the valence electrons. Silicyne is a single linear molecule composed of just silicon atoms. One of the manners they are bonded to each other in a succession of double-bonded silicons, analogous to the situation of carbon found in cumulene. The other manner they may be bonded to each other is a succession of alternating single and triple-bonded silicons, analogous to the situation of carbon found in polyyne.

2-dimensional silicyne is analogous to the carbon allotrope graphyne, and similar to the silicon allotrope silicene, being a sheet of silicon atoms. In this form, the silicyne chains that link the silicene hexagons use disilyne bonding alternating with disilane bonding, analogous to polyyne.

Miller JM-2. The Miller JM-2 was an American Formula One Air Racing homebuilt aircraft that was designed by Jim W Miller and produced by JW Miller Aviation of Marble Falls, Texas. When it was available, the aircraft was supplied in the form of plans for construction by amateurs.

Design and development
Miller opted for an unorthodox configuration in developing a racing aircraft that would be as fast as possible on . The JM-2 features a cantilever mid-wing, a single-seat enclosed open cockpit under a bubble canopy, tricycle landing gear with fixed main wheels and a retractable nose wheel, and a single engine in pusher configuration, mounted within a fan shroud, with the spinner acting as the aircraft's tailcone. The fan shroud structure provides a place to mount the rudders and the tailplane is mounted high in T-tail configuration as an extension of the shroud. There is a small canard surface mounted on the nose.

The aircraft is of mixed construction, with the fuselage made from four fiberglass panels and the  span wing covered in fiberglass and resin-reinforced honeycomb material. As required by the Formula One rules, the engine used was a  Continental O-200B powerplant, the "B" being the pusher-configured version of the engine.

The JM-2 has an empty weight of  and a gross weight of , giving a useful load of . With full fuel of  the payload is .

The JM-2 was further developed into the one-of-a-kind racing aircraft, the Miller-Bohannon JM-2 Pushy Galore.

Operational history
By October 2013, three examples had been registered in the United States with the Federal Aviation Administration including the sole Miller-Bohannon JM-2 Pushy Galore. None of the aircraft remain registered.

One of the two stock JM-2s built was destroyed while racing in the Reno Air Races at Reno, Nevada on 15 September 1989, when it flew through a dust devil and broke up in flight, killing the pilot.

Dinitrobenzene. Dinitrobenzenes are nitrobenzenes composed of a benzene ring and two nitro group (-NO2) substituents.  The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene. Each isomer has the chemical formula C6H4N2O4 and a molar mass of about 168.11 g/mol. 1,3-Dinitrobenzene is the most common isomer and it is used in the manufacture of explosives.

Properties 
The dinitrobenzenes are all crystalline solids. The boiling points of the three isomers are relatively close; however, the melting points significantly differ. 1,4-Dinitrobenzene, which has the highest symmetry, has the highest melting point.

Nitrobenzenes
1,3-Dinitrobenzene. 1,3-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C6H4(NO2)2. It is one of three isomers of dinitrobenzene. The compound is a yellow  solid that is soluble in organic solvents.

Preparation 
1,3-Dinitrobenzene is accessible by nitration of nitrobenzene. The reaction proceeds under acid catalysis using sulfuric acid. The directing effect of the nitro group of nitrobenzene leads to 93% of the product resulting from nitration at the meta-position. The ortho- and para-products occur in only 6% and 1%, respectively.

Reactions 
Reduction of 1,3-dinitrobenzene with sodium sulfide in aqueous solution leads to 3-nitroaniline.  Further reduction with iron and hydrochloric acid (HCl) gives m-phenylenediamine.

1,3-Dinitrobenzene can be nitrated to 1,3,5-trinitrobenzene with nitronium tetrafluoroborate in fluorosulfuric acid at 150 °C.
