The Impact of Online STEM Teaching and Learning During COVID-19 on Underrepresented Students' Self-Efficacy and Motivation Breadcrumb

STEM and underrepresented

S Kahn, J Vertesi, S Adriaenssens, J Byeon… - Journal of College …, 2022 - nsta.org

Female students, students of color, first-generation students, and low-income students face considerable barriers in access to STEM education, leading to their underrepresentation in STEM fields. Ensuring that these students develop strong self-efficacy and motivation in STEM during the college...

Thermodynamic characterization of halide-π interactions in solution using "two-wall" aryl extended calix[4]pyrroles as model system.

Herein, we report our latest experimental investigations of halide-π interactions in solution. We base this research on the thermodynamic characterization of a series of 1:1 complexes formed between halides (Cl(-), Br(-), and I(-)) and several α,α-isomers of "two-wall" calix[4]pyrrole...

For the first time, an absolute quantification of hybrid materials obtained from the reaction of phenylphosphonic acid (PPA) with TiO2 nanoparticles under different reaction conditions is reported. Next to the amount of PPA involved in grafting to the TiO2...

Collision cross section prediction of deprotonated phenolics in a travelling-wave ion mobility spectrometer using molecular descriptors and chemometrics.

Anal Chim Acta. 2016 Jun 14;924:68-76. doi: 10.1016/j.aca.2016.04.020. Epub 2016 Apr 25.

The combination of ion mobility and mass spectrometry (MS) affords significant improvements over conventional MS/MS, especially in the characterization of isomeric metabolites due to the differences in their collision cross sections (CCS). Experimentally obtained CCS values are typically matched...

Genome Announc. 2017 Jan 12;5(2). doi: 10.1128/genomeA.01470-16.

The Namib Desert in southwest Africa is hyperarid and composed of distinct microbial communities affected by a longitudinal aridity gradient. Here, we report four soil metaviromes from the Namib Desert, assessed using deep sequencing of metavirome libraries prepared from...

Chemical composition of an aqueous oxalato-/citrato-VO(2+) solution as determinant for vanadium oxide phase formation.

Inorganic chemistry

Peys N, Maurelli S, Reekmans G, Adriaensens P, De Gendt S, Hardy A, Van Doorslaer S, Van Bael MK.

Inorg Chem. 2015 Jan 05;54(1):69-78. doi: 10.1021/ic5015779. Epub 2014 Dec 17.

Aqueous solutions of oxalato- and citrato-VO(2+) complexes are prepared, and their ligand exchange reaction is investigated as a function of the amount of citrate present in the aqueous solution via continuous-wave electron paramagnetic resonance (CW EPR) and hyperfine sublevel...

Scope and limitations of a new highly selective synthesis of unsymmetrical monomers for the synthesis of precursors toward poly(arylenevinylene)s.

The Journal of organic chemistry

Van Der Borght M, Vanderzande D, Adriaensens P, Gelan J.
PMID: 10813931
J Org Chem. 2000 Jan 28;65(2):284-9. doi: 10.1021/jo990111k.

In our laboratory a precursor route to poly(p-phenylenevinylene) derivatives is developed in which unsymmetrically substituted p-xylene derivatives, possessing a benzylic sulfinylalkyl group, are used as monomers. Because of this unsymmetry, we were forced to investigate thoroughly the synthesis of...
