“…33 ESI-MS is the typical method for paraquat analysis but requires extraction from tissue. 34 Characterization of crystal violet dye in blue ink from the surface of paper was also demonstrated using the melting point tube surface sampling strategy and in-source fragmentation (Figure 3II). MAI-MS of the surface ink sample in the absence of applied cone voltage yields primarily the crystal violet cation (m/z 372) .…”

Matrix-assisted ionization (MAI)-mass spectrometry (MS) eliminates the need for high voltage, a heat source, lasers, and compressed gases in the ionization process and uses minimal solvents in sample preparation, thus making MAI ideal for field-portable mass spectrometers. The broad applicability of MAI is demonstrated by simple, rapid, and robust positive and negative detection mode analyses of low and high mass compounds including some pesticides, dyes, drugs, lipids, and proteins (186 Da to 8.5 kDa) from various materials including urine, biological tissue sections, paper, and plant material on a low pumping capacity, single-quadrupole mass spectrometer. Different sample introduction methods are applicable, including the use of a pipet tip or glass melting point tube, allowing integration of sample preparation with sample introduction for increased analytical utility and ease of operation, even when sampling directly from surfaces.

Structural mechanics is an important basic course for undergraduates majoring in civil engineering. However, due to the difficulty and extent of the content, students are often not able to master the course. Problem-based learning is an excellent way of teaching engineering, and character education can improve students’ performance. This study explores the combined application of problem-based learning and exemplarist moral theory. In this model, students analyze the structure and force of buildings, and they learn about the historical stories behind them. In this way, students improve their morality, civility, performance, and intellect. In character education, the use of case studies and examples can increase students’ interest in the course, improve classroom participation, enrich teaching connotations, and strengthen students’ understanding of basic concepts and their ability to memorize them.
