A Systematic Review of the Education and Awareness Interventions to Prevent Online Child Sexual Abuse.

Online child sexual abuse is highly prevalent in current society, in part, due to how technologically advanced children and adults have become. While much of the focus has been on perpetrator intervention, it is prudent to consider responses safeguarding children from potential perpetrators. Therefore, this review aimed to identify all the available empirical research on the prevention methods linked to education and awareness to determine the approaches' effectiveness, successes, and failures to aid future interventions.

Solvent-Free Synthesis and Fluorescence of a Thiol-Reactive Sensor for Undergraduate Organic Laboratories.

A green organic laboratory experiment was developed in which students synthesize a sensor for thiols using a microscale, solventless Diels-Alder reaction at room temperature or 37 °C. The molecular probe is easily purified by column chromatography in a Pasteur pipet and characterized by thin-layer chromatography and NMR spectroscopy. The thiol-reactive sensor becomes intensely fluorescent upon exposure to thiols from -acetylcysteine, bovine serum albumin, or human hair (pretreated with a reducing agent to reveal cysteine thiols in α-keratin).
