GEMOLOGY, MINERALOGY, AND SPECTROSCOPY OF GEM-QUALITY DIOPSIDE FROM PAKISTAN AND RUSSIA: NEW INSIGHTS FOR THE CHROMOGENIC MECHANISM AND POSSIBLE ORIGIN

Green diopside is currently popular in the jewelry market due to its attractive color and excellent transparency.Gem-quality diopsides are mainly sourced from Pakistan, Italy, Russia, and other places.The color, geographic origin, and formation mechanism are the main factors affecting the value of gemstones, which can be determined by examining the

Based on the results from rock thin section observation, casting thin section identification, high-pressure mercury injection, rate-controlled porosimetry, X-ray diffraction, and high resolution field emission CMOS scanning election microscope observation and analysis, influences of feldspar minerals on the storage and permeability conditions in Ch

The transition from nucleate to film boiling on micro/nanotextured surfaces is of crucial importance in a number of practical applications, where it needs to be avoided to enable safe and efficient heat transfer.Previous studies have focused on the transition process at the macroscale, where heat transfer and bubble generation are activated on an a

Transformational leadership has gained a great deal of attention since its development through research and evaluations from James MacGregor Burns and Bernard Bass.But central to its development, there are still uncertainties regarding the attributes and interventions of transformational leadership style in Audio Connector developing nations like N
