High-resolution mass spectrometry (HRMS) is an analytical technique that is typically used by mass spectrometry experts. However, with recent advancements, it is becoming more accessible to students in organic chemistry laboratories. Still, a significant knowledge gap exists between these experts and students. A straightforward laboratory…

This laboratory experiment aims to provide undergraduate students with research experience in water treatment by membrane separation. This experiment includes fabrication and characterization, as well as water treatment applications of the interfacially polymerized polyester nanofiltration membranes. Through participating in this experimental…

The pharmaceutical and medicine manufacturing industry has become the largest industrial sector for the employment of chemists, indicating a need for experiments with a pharmaceutical sciences context in the undergraduate chemistry curriculum. In the pharmaceutical industry, testing drug dissolution is a key analytical task for solid oral dosage…

A research-style laboratory experiment composed of the synthesis of MOF-74 materials, related structural characterization, and the cutting-edge application of electrocatalytic oxygen evolution reaction (OER) has been designed toward advanced undergraduates at East China University of Technology (ECUT). The desired monometallic MOF-74 (Ni-MOF-74…

As the field of educational neuroscience continues to grow, questions have emerged regarding the ecological validity and applicability of this research to educational practice. Recent advances in mobile neuroimaging technologies have made it possible to conduct neuroscientific studies directly in naturalistic learning environments. We propose that…

Transforming fluorescence spectrometers into cost-effective, portable devices provides the potential for field-based applications in biological, environmental, and clinical research and education. However, the majority of developed spectroscopic technologies continue to require heavy, expensive equipment and trained personnel for operation or do…

Science educators strive to teach students how to be well-rounded scientists with the ability to problem solve, anticipate errors, and adapt to unexpected roadblocks. Traditional organic chemistry experiments seldom teach these skills, no matter how novel or contemporary the subject material. This paper reports on the success of a quarter-long…

This paper reports a laboratorial internship included in the Portuguese Science and Technology promotion program "Internships for Young People in Laboratories (Ciência Viva no Laboratório)", which provided high school students an opportunity to approach the reality of scientific and technological research in a higher education…

A research project for senior undergraduates of chemistry has been developed to introduce syntheses of a series of monodispersed semiconductor PbS quantum dots (QDs) and their characterization methodologies. In this paper, we report the preparation of monodispersed semiconductor PbS QDs with sizes smaller than the exciton Bohr radius using a…

This communication is a collection of additions and modifications to two previously published classic inorganic synthesis laboratory experiments. The experimental protocol for the synthesis and isolation of enantiomerically enriched ?- (or ?-)Co(en)[subscript 3]I[subscript 3] has been modified to increase reproducibility, yield, and enantiomeric…

A laboratory experiment was designed for undergraduate students, in which the outcome of an easy single-step organic synthesis with well-defined conditions was not elucidated until the end of the exercise. In class, students predict and discuss the possible products using their knowledge of reaction mechanisms. In the laboratory, they learn how to…

Introducing students to a multidisciplinary research laboratory presents challenges in terms of learning specific technical skills and concepts but also with respect to integrating different technical elements to form a coherent picture of the research. Here we present a multidisciplinary series of experiments we have developed in the Electronic,…

Upon stimulation, real time maps of cortical hemodynamic responses can be obtained by non-invasive functional near-infrared spectroscopy (fNIRS) which measures changes in oxygenated and deoxygenated hemoglobin after positioning multiple sources and detectors over the human scalp. The current commercially available transportable fNIRS systems have…

One of the most challenging tasks in neuroscience in language studies, is investigation of the brain's ability to integrate and process information. This task can only be successfully addressed by applying various assessment techniques integrated into a multimodal approach. Each of these techniques has its advantages and disadvantages, but help to…

The main objectives of the study were: to investigate whether training on working memory (WM) could improve fluid intelligence, and to investigate the effects WM training had on neuroelectric (electroencephalography--EEG) and hemodynamic (near-infrared spectroscopy--NIRS) patterns of brain activity. In a parallel group experimental design,…
