ttugoniot data in the 4to 250-kb stress range were obtained for quartzite and novaculite, sandstones of varying porosity, single-crystal calcite, marble, porous and nonporous limestone, several plagioclases of varying composition, and a basalt. Conventional plane-wave, in-contact explosive assemblies were used; the shock state was computed from measured shock velocities; particle velocities are...

Hollow carbon-based nanostructures (HCNs) have found broad applications in various fields, particularly rechargeable batteries. However, the syntheses of HCNs usually rely on template methods, which are time-consuming, low-yield, and environmentally detrimental. Metal-organic frameworks (MOFs), constructed by organic ligands inorganic metal nodes, been identified as effect platforms for prepari...

Fingerprints are unique to individuals and play an important role in the investigations at crime scene. Today searches for developing best methods detect fingerprints that not completely visible or have sufficient characteristics still ongoing. In this study, 2448 were used as samples collected from four individuals, between 24-50 years old, two women men, who signed consent form material. Poro...

Two novel cadmium-organic frameworks containing achiral helical nanotubular channels, [Cd(HImDC)(S)](n) (S = Im(1) and Py(2)), have been synthesized and characterized using single crystal X-ray diffraction, in which 1 converts to 2 upon refluxing 1 in pyridine solution with noticeable porosity and hydrogen uptake at medium pressure.
