The .50 GI (12.7×23mmRB) pistol cartridge was developed by Alex Zimmermann of Guncrafter Industries.The .50 GI was introduced at the 2004 SHOT Show alongside the Guncrafter Industries Model No. 1, a variation of the M1911.
Guncrafter Industries introduced a smaller version of Model No. 1 in 2010. The Model No. 3 is a Colt Commander-sized 1911 also chambered for .50 GI, with a shorter barrel but with a full-length grip.
This suggests an origin for the efficacy of NHC transfer chemistry from Ag NHC complexes, with weaker M-NHC bonds in addition to the straightforward synthetic route described previously. [5] Further charge-decomposition analysis of the three model complexes suggests that the- major contribution to covalent bonding arises from the NHC to M σ ...
Atoms in Molecules bond energy at critical point calculations show that the N to Si bonds in an NHSi are significantly ionic, unlike the highly covalent N-C bond in an NHC. Furthermore, the charge density and the Laplacian (∇ 2 ) at the bond critical points between the silylene and carbene are dissimilar.
The M939 and M939A1 models use a Cummins NHC 250, a 855 cubic inches (14.0 L) naturally aspirated inline 6 cylinder diesel engine developing 240 horsepower (180 kW) at 2100 rpm and 685 pound force-feet (929 N⋅m) of torque at 1,500 rpm. [8] This was the standard engine of the M809 series.
In coordination chemistry, a transition metal NHC complex is a metal complex containing one or more N-heterocyclic carbene ligands. Such compounds are the subject of much research, in part because of prospective applications in homogeneous catalysis. One such success is the second generation Grubbs catalyst. [1] IMes is a popular NHC ligand.
The traditional 5-membered CAACs show similar nucleophilicity to the eight-membered NHC with calculated highest occupied molecular orbitals (HOMO) of 5.290 eV (CAAC-5) vs. 5.110 eV (NHC-8), decreasing the motivation to synthesize expanded ring CAACs. [14] As a result, ring-expanded CAACs have not been widely explored.
M54 (M39 series) M813 (M809 series) M923 (M939 series). The 5‑ton 6x6 truck, officially "Truck, 5-ton, 6x6", was a class of heavy-duty six-wheel drive trucks used by the US Armed Forces.
