The benzoin condensation of benzaldehyde is a staple of the undergraduate organic chemistry laboratory, introducing the current topic of nucleophilic carbene organocatalysis. Our procedure makes notable improvements to current practice, including the elimination of solvent waste and an "18-fold reduction of reaction time." We have…

A laboratory experiment was developed to introduce systems thinking and green chemistry concepts through the synthesis of the antidepressant and smoking cessation aid, bupropion hydrochloride. The traditional synthesis has several issues from a green chemistry perspective: it uses the toxic solvents N-methylpyrrolidinone (NMP) and dichloromethane…

A suitable combined laboratory experiment can involve more chemical disciplines and form students' views on practical connections. A laboratory experiment has been prepared focusing on the adsorption of the dangerous Co(II) ion using natural adsorbents representing waste material of a polysaccharide and keratin nature. Efficiency of Co(II)…

With the rapid growth in the manufacturing industry and increased urbanization, higher amounts of composite material waste are being produced, causing severe threats to the environment. These environmental concerns, coupled with the fact that undergraduate students typically have minimal experience in research, have initiated the need at the UAE…

Developing a broadly based positive culture of safety in undergraduate instructional laboratory settings remains a significant challenge for chemical educators. An enhanced safety component has been developed for an upper-level laboratory course based on earning a Chemical Hygiene and Safety badge. The badge requires student engagement in…

School principals are responsible for occupational health and safety (OHS) issues that may arise, and they play a critical role in ensuring that health and safety procedures in schools. The purpose of this study is to determine how occupational health and safety practices in schools can be improved with reference to the views of school principals.…

The main aim of this paper was to analyze how medicinal gardens in secondary schools can improve teaching-learning processes in rural settings. The sample comprised 179 students (69.3% girls) from a rural public secondary school in the province of Huila (Colombia). The age of the participants ranged from 15 to 17 years with a mean of 15.86 years…

The Factories Act of 2004, the Employee Compensation Act of 2010, the Minerals Oil Safety Regulation of 1999 and the Harmful Waste Act of 2004 are pieces of legislation that included provisions for the safety, health and welfare of Nigerian workers beyond the Constitution of the Federal Republic of Nigeria 1999, and the Labour Act of 2004. This…

Purpose: Universities are an example of institutions that aggregate people around work/study who consume water, energy and produce waste daily in their activities, generating an impact on the environment. The purpose of this study is to determine the quantity, composition and recycling potential of waste generated at the Faculdade UnB Planaltina…
