Experience of Students in Online Courses v. Students in Lecture Courses

My research project investigates the experience of students who are enrolled in online courses, specifically Organic Chemistry II and their experiences in Organic Chemistry I compared to those they are now having. The sample was composed of seven men, four whites and three blacks. One was a professor and the six students ages ranged from 20 to 22 years of age. The participants were interviewed and were asked to give their opinion about the format of Organic Chemistry II. The results indicted that race did not play a factor in which format was preferred by the subjects, the majority of whom liked the online format. Their biggest complaint concerned the exam format. These findings could be used to find a balance that will be acceptable to faculty, but will enable students to effectively learn in different environments

The 24th IUPAC International Conference on Physical Organic Chemistry (ICPOC 24)

The IUPAC sponsored biennial Conference on Physical Organic Chemistry (ICPOC) series bear a long history and a solid reputation as the leading international gatherings on Physical Organic Chemistry. Since their first installment in Crans sur Sierre (Switzerland) in 1972, ICPOC meetings have been held in Noordwijkerhout (The Netherlands, 1974), Montpellier (France, 1976), York (UK, 1978), Santa Cruz (USA, 1980) Louvain-la-Neuve (Belgium, 1982), Auckland (New Zealand, 1984); Tokyo (Japan, 1986), Regensburg (Germany, 1988), Haifa (Israel, 1990), Padua (Italy, 1994), Incheon (Korea, 1996), Florianopolis (Brazil, 1998), Göteborg (Sweden, 2000), San Diego (USA, 2002), Shanghai (China, 2004), Warsaw (Poland, 2006), Santiago de Compostela (Spain, 2008), Busan (Korea, 2010), Durham (UK, 2012), Ottawa (Canada, 2014), Sidney (Australia, 2016). The 24st IUPAC International Conference on Physical Organic Chemistry (ICPOC 24) was held at the University of Algarve, in Faro, Portugal, July 1–6, 2018.info:eu-repo/semantics/publishedVersio

Organic chemistry on Titan

Observations of nonequilibrium phenomena on the Saturn satellite Titan indicate the occurrence of organic chemical evolution. Greenhouse and thermal inversion models of Titan's atmosphere provide environmental constraints within which various pathways for organic chemical synthesis are assessed. Experimental results and theoretical modeling studies suggest that the organic chemistry of the satellite may be dominated by two atmospheric processes: energetic-particle bombardment and photochemistry. Reactions initiated in various levels of the atmosphere by cosmic ray, Saturn wind, and solar wind particle bombardment of a CH4 - N2 atmospheric mixture can account for the C2-hydrocarbons, the UV-visible-absorbing stratospheric haze, and the reddish color of the satellite. Photochemical reactions of CH4 can also account for the presence of C2-hydrocarbons. In the lower Titan atmosphere, photochemical processes will be important if surface temperatures are sufficiently high for gaseous NH3 to exist. Hot H-atom reactions initiated by photo-dissociation of NH3 can couple the chemical reactions of NH3 and CH4 and produce organic matter

Quantum dot-labelled polymer beads by suspension polymerisation

CdSe quantum dots with polymerisable ligands have been incorporated into polystyrene beads, via a suspension polymerisation reaction, as a first step towards the optical encoding of solid supports for application in solid phase organic chemistry

How do Structural Formulas Embody the Theory of Organic Chemistry?

Organic chemistry provides fertile ground for scholars interested in understanding the role of non-linguistic representations in scientific thinking. In this discipline, it is plausible to think of textual representation as supplementing theories whose principle expression is diagrammatic. Among the many sorts of diagrams employed by organic chemists, structural formulas are the most important. In this paper, by examining two central episodes in the development of structural formulas -- Kekulé’s proposal of a structure for benzene and Ingold’s explanation of dipole moments in terms of ‘mesomerism’ – I investigate how the norms for the production and interpretation of structural formulas evolve in response to experimental results. I conclude that one principle way in which structural formulas embody the theory of organic chemistry is through these evolving norms

The Effects of Prior Calculus Classes on Success in Organic Chemistry

Within University of Nebraska – Omaha (UNO) chemistry-based degree programs, organic chemistry along with at least two semesters of calculus are required courses. There is, however, no requirement for the order in which these courses should be taken. This is mainly due to the notion that for chemistry courses, organic chemistry is detached from the typical quantitative concepts studied in other chemistry-based courses. This is untrue, however, as many organic chemistry concepts rely on three-dimensional spatial visualizations and manipulations. Spatial awareness skills are strengthened within higher-level calculus classes. A survey was administered to organic chemistry students enrolled in 2022-2023. The students were surveyed and interviewed to determine correlations between taking calculus courses and grades received in the first semester of organic chemistry as well as their confidence levels toward concepts related to three-dimensional spatial visualizations. The results of this survey will be discussed to show the effects of taking calculus prior to taking organic chemistry and general student success with organic chemistry concepts
