The objective of the present study was to obtain the ballistic characteristics of the igniting primer (electrical ignitor) for the 18×45T cartridges of the 'Osa' pistol produced by different manufacturers. The experiments included a series of shots fired from the 'Osa' pistol with the use of cartridges having an energy of 85 Joules ('Novye oruzheinye tekhnologii', Ltd., Sergiev Posad) and 88 Joules ('A+A', Ltd, Tula). The shooting distance varied from the point blank range to 5, 10, 20, 30, 40, and 50 cm. The targets were either the femoral soft tissue of the cut-off human lower extremity, white cotton fabric, and the 1-5 cm high gelatin cylinder 25 cm in diameter. The experiments have demonstrated that the igniting primer (electrical ignitor) for the cartridges manufactured by the 'Novye oruzheinye tekhnologii', Ltd., Sergiev Posad, served as an additional factor of the shot responsible for the penetrating power of the ammunition at a distance of 50 cm. The data on the composition of metals used for the manufacturing of the igniting primers under consideration are presented.

Aqueous aluminum ion batteries (AAIBs) possess the advantages of high safety, cost-effectiveness, eco-friendliness and high theoretical capacity. However, the AlO film on the Al anode surface, a natural physical barrier to the plating of hydrated aluminum ions, is a key factor in the decomposition of the aqueous electrolyte and the severe hydrogen precipitation reaction. To circumvent the obnoxious Al anode, a proof-of-concept of an anode-free AAIB is first proposed, in which AlTiO, as a cathode pre-aluminum additive (Al source), can replenish Al loss by over cycling.

1- and 2-Tetrazolylacetonitrile (1- and 2-TAN) have been synthesized by the reaction of chloroacetonitrile with 1H-tetrazole under basic conditions. They further were reacted with sodium azide in the presence of zinc(II) chloride to form 5-((1H-tetrazol-1-yl)methyl)-1H-tetrazole (1-HTMT) and 5-((2H-tetrazol-2-yl)methyl)-1H-tetrazole (2-HTMT). The nitrogen-rich compounds have been applied as ligands for Energetic Coordination Compounds (ECCs) and show interesting coordinative behavior due to different bridging modes.

For most patients, direct oral anticoagulants (DOACs) are preferred over vitamin K antagonists for stroke prevention in atrial fibrillation and for venous thromboembolism treatment. However, randomized controlled trials suggest that DOACs may not be as efficacious or as safe as the current standard of care in conditions such as mechanical heart valves, thrombotic antiphospholipid syndrome, and atrial fibrillation associated with rheumatic heart disease. DOACs do not provide a net benefit in conditions such as embolic stroke of undetermined source.
