Aryl aldehydes I reacted with 1‐benzosuberone to yield the corresponding 2‐arylidene‐1‐benzosuberones II. Condensation of II with hydrazine and its derivatives provided the substituted 2,3,3a,4,5,6‐hexahydro‐benzo[6,7]cyclohepta[1,2‐c]pyrazoles III‐VI respectively. The structures of all products were assigned by chemical and spectroscopic methods.

Environmental literacy EL is a significant aspect that must be implanted in education; to continuously protect environment systems, communities, and future generations. Students should understand skills and motivation to make responsible decisions for a sustainable environment. This research aimed to assess student EL and evaluate the influence of demographic factors on the EL level among students at Applied Science Private University in Jordan. A total of 323 students; 53.6% male, and 46.4% females- took the EL test. The test had three parts: student’s demographic profile, environmental knowledge, and attitude. The findings indicated that students had high environmental knowledge of energy, pollution, and recycling. The results also showed that students had a moderate level of environmental knowledge on issues such as environmental concerns, ecology, water scarcity, global warming, and ozone layer depletion. The lower mean scores were determined for items on time of gardens irrigation and flue gas. It also revealed no differences between Gender, faculty, cumulative average, and income levels affect EL. Multimedia alongside books and school environmental experience served as the key source of environmental information. It concluded that environmental knowledge does not always influence the behavioral intentions, so a national strategy is needed to improve current curricula in higher education institution.

Natural inhibitors are the most crucial manner to lessen the corrosion price of various business metals. There are several strategies being used with corrosion inhibitors. One technique being used is the Electrochemical strategies. The gain with this technique is their brief size time and mechanistic information. It is beneficial in the corrosion's layout safety techniques besides the layout of the brand new inhibitors, there are 3 styles of corrosion inhibitors as anodic inhibitors, cathodic inhibitors, over one inhibitor. The corrosion inhibition of slight metallic in 1.0 M HCl solution with the aid of using Jordanian -Bay- leaves extract has been studied with the use of potentiodynamic polarization technique. Results received a display that Bay- leaves aqueous extract behaves as an anodic inhibitor for slight metallic in 1.0 M HCl solution. The inhibitor capabilities thru adsorption following Temkin adsorption isotherm. The impact of parameters like temperature and inhibitor awareness at the corrosion of slight metallic has additionally been studied.

Formaldehyde has become a prominent topic of interest because of its simple molecular structure, release from various compounds in the near vicinity of humans, and associated hazards. Thus, several researchers designed sophisticated instrumentations for formaldehyde detection that exhibit real-time sensing properties and are cost-effective and portable with high detection limits. On these grounds, this review is centered on an analysis of optical chemosensors for formaldehyde that specifically fall under the broad spectrum of organic probes. In this case, this review discusses different organic functionalities, including amines, imines, aromatic pillar arenes, β-ketoesters, and β-diketones, taking part in various reaction mechanisms ranging from aza-Cope rearrangement and Schiff base and Hanztch reactions to aldimine condensation. In addition, this review distinguishes reaction mechanisms according to photophysical phenomena, that is, aggregation-induced emission, photoinduced electron transfer, and intramolecular charge transfer. Furthermore, it addresses the instrumentation involved in gas-based and liquid formaldehyde detection. Finally, it discusses the gaps in existing technologies followed by a succinct set of recommendations for future research.
