Biodiesel was synthesized from locally sourced, on-campus, dining facility waste cooking oil and grease by base-catalyzed transesterification with methanol. The components properties of the biodiesel were characterized gas chromatography–mass spectrometry (GC–MS), Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR (1H 13C)), inductively coupled plasma-mass (ICP–MS), viscometer, bomb calorimetery. Five major fatty acid methyl esters (FAMEs) in oleate, linoleate,...

The positive impact of undergraduate research on students' success in college is well documented.Many, however, have questioned the traditional apprentice-style model research, raising concerns about who gets these experiences, how experiences enhance scientific capability and student persistence, might be improved to get more "bang for buck" terms a higher-performing workforce.Research are usually geared toward selected students, such as those entering graduate or professional schools.Where...

As part of local sustainability efforts, biodiesel was synthesized via transesterification using a deep eutectic solvent (DES) without further washing from on-campus, dining facility waste cooking oil and grease. Before moving forward with repurposing used DES as in chemistry teaching labs, we determined the suitability an alternative fuel blended diesel to power campus utility vehicles. Biodiesel components were characterized by gas chromatography–mass spectrometry (GC–MS), Fourier...

Ultrathin (1−10 layers) aniline and pyridine films deposited on a Ag(111) surface at 90 K have been examined using thermal programmed desorption (TPD). Multiple peaks observed for both systems showing film growth from the first chemisorbed layer to bulk structure through multiple intermediate layers. The mechanisms two are, however, apparently different. Aniline are formed one time with five thermodynamically stable layered structures. In contrast, grow metastable phases, similar benzene...

BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of undergraduate biology curriculum. The Department Chemistry Life Science at West Point responded by developing a required chemistry course tailored to interests life majors. To overcome student resistance chemistry, students were enabled as long-term stakeholders who would shape syllabus selecting topics interest them. initial 2 yr assessment indicates that have positive view course, feel they...

Mathematics competency in nursing education and practice may be addressed by an instructional variation of the traditional dimensional analysis technique typically presented beginning chemistry courses.The authors studied 73 students using typical technique. Student quantitative problem-solving performance was evaluated.Students scored significantly better (18.3 20 points, p < .0001) on final examination titration problem than those who used (10.9 points).

Pulsed 266 and 355 nm ultraviolet laser irradiation of monolayer vinyl chloride physisorbed on Ag(111) results in molecular dissociation leading to C2H3 Cl, much which is adsorbed the surface. On basis observations made dependences chlorine isotope photon energy, it deduced that upon excitation forms a transient negative ion through substrate mediated, vertical electron attachment mechanism. The anion either dissociates or relaxes energy transfer neutral state causing molecule desorb....

Reviewing the eBook Organic Chemistry by Bryan C. Sanctuary reveals a useful supplementary resource for students enrolled in an undergraduate organic chemistry course or seeking condensed review of organic, such as those preparing graduate professional school admission exams.

Students of biology and chemistry traditionally make 3x5 flash cards to assist learning nomenclature, structures, reactions. Advances in educational technology over the past ten years have enabled viewed on computers, offering an endless array drilling feedback for students.
