The hallmark of game-based learning is that students discover concepts through trial and error as they play. With the digital landscape in higher education shifting to mobile-first, new tools for chemistry are both possible needed. Interactive games bring intuitive content directly their devices. game Chairs! was created teach ring flip cyclohexane. development this mobile tool organic its implementation classrooms described.

A 6.8 fold increase in the rate of epoxidation (Z)-cyclooctene with m-chloroperbenzoic acid is observed upon addition catalyst trifluoroacetic acid. Kinetic and theoretical studies suggest that this due to complexation peroxy undissociated (HA) rather then protonation The transition structure for oxidation ethylene protonated peroxyformic exhibits a spiro orientation electrophilic oxygen at QCISD/6-31G(d) level complexed (HCO3H·HA) state also essentially ab initio density functional levels....

The reactant cluster and transition state for epoxidation of allyl alcohol with peroxyformic acid have been located at the MP2/6-31G(d) level theory. free energy activation (Δ = 19.8 kcal/mol) predicted MP4//MP2/6-31G(d) is quite comparable experimental data 3-hydroxycyclohexene 19.7 kcal/mol). A spiro (TS) was found where plane defined by peroxyacid moiety oriented 89° to CC bond axis. Intrinsic reaction coordinate analysis suggests that after barrier crossed a 1,4-hydrogen migration...

Enantiomerically pure β-arylalkyl carboxylic acids are important synthetic intermediates for the preparation of a wide range compounds with biological and pharmacological activities. A library 83 enzymes isolated from metagenome was searched activity in hydrolysis ethyl esters three racemic phenylalkyl by microtiter plate-based screening using pH-indicator assay. Out these, 20 were found to be active subjected analytical scale biocatalysis order determine their enantioselectivity. The most...

Successfully learning principles from drawing Lewis Structures sets the foundation for understanding more complex representations of structural concepts in chemistry. As these visual-based are core competencies chemical pedagogies, it is incumbent and required educational institutions faculty to provide usable accommodations all students, including those with blindness low-vision (BLV).

Introduction: Visual model comprehension and application are important for success in science, technology, engineering, mathematics (STEM) courses. As educational materials shift to primarily digital content with dynamic interactive visuals, students visual impairments at risk being disadvantaged, since few interactives born accessible. To fill this gap of accessible STEM learning tools, we designed tested the Kasi Learning System. uses tactile manipulatives computer vision audio-based...

The mechanism maps that guide student instruction in organic chemistry curricula are structural representations of bond-breaking and bond-making events transform a reactant into product. For students, these pathways represented by electron pushing formalism (EPF) can be challenging to navigate. instructors, providing formative feedback students support their learning the EPF arrow system is difficult provide timely manner. Mechanisms App ("the App") was developed as method for explore...

Abstract Agencies in charge of flood management use disaster reports (DRs) as the preferred source information on past flooding events. A systematic survey DRs prepared by Italian agencies suggests that could be widely enhanced view targeting more effective communication to citizens, reinforcing pillar civil protection planning and management, improving resilience population extreme Without loss rigor details required for all usual technical uses DRs, we suggest recompiling them form...

The interactions between paint/adhesive polymers and metal surfaces that are critical for adhesion have been studied theoretically. This study used zinc oxide as a model of galvanized steel surface, ammonia, water, ethylene models amino, hydroxy, unsaturated functionalities in polymers. Ab initio molecular orbital calculations were carried out on dimer. Geometries optimized at the HF/3-21G level relative energies calculated by CASSCF/3-21G MP2 with DZP basis set Wachters Hay. Ethylene forms...

As digital educational media use becomes more widespread, an opportunity exists to develop new methods present abstract ideas provide a meaningful learning experience. Drawing from psychology and dynamic visualization research, interactive tools can be thoughtfully designed but it is also necessary establish how these are used study the effects have on concept understanding. In this technology report, we Hybridization Explorer, web-based tool for manipulating experimenting with hybridization...

<p>The abstract nature of atomic and hybrid orbitals makes it a challenging concept for students to understand. Presented is the Hybridization Explorer, web-based interactive learning tool, manipulating experimenting with hybridization concepts. Through explorer can explore both combination orbitals, visual representation corresponding bond formation. Case studies from an undergraduate graduate-level demonstration are described. Finally, self-reported student confidence levels on...

The lack of basic information about the area where people live and major hydrometeorological disasters that occurred in past can lead population to underestimate flood risk. risk perception is often related only direct experiences memory floods took place same areas. However, this high during weeks follow a event then decreases rapidly.In Italy, regional agencies charge management widely use disaster reports (DRs) as preferred way collect standardize on flooding events meteorological...

Young carers have specific needs that are not being met and this initiative provides information advice training to anyone who works with young their families. The website an online forum for those working carers, sharing ideas experiences identifying scope collaborative project work.
