Article Synopsis
- Revamping energy storage structures can optimize the performance and safety of energetic materials, which is essential for achieving high energy outputs with reduced sensitivity.
- This research focuses on a new compound, ECCs [Cu(HDMPZCA)(ClO)](ClO)·2HO, that combines ionic salts and coordination compounds for improved properties compared to previous materials.
- The new compound demonstrates higher oxygen balance and mechanical sensitivity, alongside promising ignition capabilities and explosive power, positioning it as a strong candidate for use as a primary explosive.
Article Synopsis
- The structure of energetic compounds significantly influences their performance, with even slight variations impacting their effectiveness in different application scenarios.
- Researchers synthesized two silver(I)-based complexes, ECPs-1 and ECPs-2, using isomeric ligands, and confirmed their structures through various analytical methods.
- Although both complexes have good thermal stability, ECPs-2 shows lower thermal decomposition temperature and mechanical sensitivity while demonstrating stronger explosive power, making it a potential candidate for applications such as laser initiation.
Article Synopsis
- 2,4,6-triazide-1,3,5-triazine (TAT) is being studied for its potential in creating high-energy density materials, with structural changes occurring under high pressure (up to 30 GPa).
- Researchers noted specific changes in TAT's molecular structure, such as straightening and gathering of nitrogen groups, along with significant modifications in its vibrational properties as pressure increases, observable through Raman spectroscopy.
- The investigation utilized advanced computational methods (dispersion corrected density functional theory) to analyze TAT's behavior under compression, indicating critical changes in its electronic properties and band gap at defined pressure points (4.5 GPa and 8.0 GPa).
In order to preserve the coordinating ability of the hydrazide group, we used retrosynthetic analysis to design and synthesize ligand furan-2,5-dicarbohydrazide and its complex [Cu(FDCA)(HO)ClO](ClO)·HO (). The structure of the product was confirmed by single-crystal X-ray diffraction, infrared spectroscopy, and elemental analysis. The solvent-free target material exhibited good thermal stability, sensitivity to mechanical stimuli, and excellent explosive properties.

Then, FRCA and Cu(ClO) were used to synthesize coordination compounds [Cu(FRCA)(HO)(ClO)]·CHOH () and Cu(FRCA)(HO)(ClO) (). The structure of the was confirmed by single-crystal X-ray diffraction, IR and EA characterization.

Methods: We performed a computerized search of phase II/III clinical trial databases of CIK cell-based therapy using a combination of the terms 'cytokine-induced killer cells', 'tumor' and 'cancer'.
Results: Treatment with CIK cells was associated with a significantly improved half-year survival (P = 0.
Objective: To evaluate the feasibility and safety of the modified urethral pull-through procedure for the treatment of posterior urethral stricture or atresia.
Methods: We retrospectively analyzed 212 cases of posterior urethral stricture or atresia treated by the modified urethral pull-through procedure. The length of the stricture or atresia was 1.
