The purpose of this work is to provide spectroscopic evidence possible chemical pathways that took place in the formation fossil resins Class I . natural polymerization process mimicked laboratory using pure communic acids (terpene derivatives) as reactants, which were subjected controlled temperature treatment. We shall focus here on trans ‐, cis ‐ and iso‐/mirceo acid isomers, temperature‐induced reactivity discussed basis different arrangements conjugated double‐bonds moieties monomeric...
The objective of this study is to investigate the effects high pressure processing on molecular structure some unsaturated fatty acids. Samples elaidic acid, linoleic ZE and EE conjugated acid are treated at 293 or 333 K pressures up 700 MPa. It observed that adiabatic heat generated from compression able bring sample temperature above 373 after These relatively extreme conditions great interest for food sterilization, but they may induce undesirable change in quality characteristics. To...
We present Raman spectroscopy experiments in dimethylacetylene (DMA) using a sapphire anvil cell up to 4 GPa at room temperature. DMA presents phase transitions 0.2 (liquid I) and 0.9 GPa, which have been characterized by changes the spectrum of sample. At pressures above 2.6 several bands split into two components, suggesting an additional transition. The sample is identical that found for monoclinic II (C2/m) low temperatures, except splitting band assigned fourfold degenerated asymmetric...
El confinamiento relacionado con el COVID ha forzado la introducción de metodologías docentes no presenciales incluso en las prácticas laboratorio. Una ellas es virtualización que permita una alternativa presencial caso dificultades para su realización. Hay disponibles muchos programas comerciales permiten dicha virtualización, pero un mejor encaje entre convencionales y virtuales, se procedido a programación herramientas cálculo específicas mediante Visual Basic Excel. En este trabajo...
Interest in developing 21st Century Skills, particularly Problem-Solving (PS) abilities Science Education, has grown recent years.This study presents the design and validation of an analytic rubric to quantitatively assess PS performance 23 students enrolled Water Resources (WR) degree program at Rey Juan Carlos University Madrid, Spain.The evaluated students' through conveniently designed ill-structured problems within a General Chemistry course.The consists three dimensions, each...
The main purpose of this study is to provide spectroscopic evidence possible chemical pathways in the formation fossil resins under high pressure conditions. In work, we have studied trans-communic acid (majority precursor compound resinites) conditions by using a sapphire anvil cell. Raman spectra were measured at atmospheric up 8 GPa (at room temperature). Slight changes observed spectra. Furthermore, recovered sample after release was analyzed FTIR. Our results are not conclusive about...
