Abstract:
General chemistry is the first undergraduate course in which students further develop their understanding of fundamental chemical concepts. Many of these fundamental topics highlight the numerous conceptual interconnections present in chemistry. However, many students possess incoherent knowledge structures regarding these topics. Therefore, effective assessments are needed to identify these interconnections. The use of concept-mapping and think-aloud interviews to investigate the knowledge structures of undergraduate organic chemistry students' regarding bonding concepts is the focus of this

Abstract:
The principles of chemistry learning emphasize that students study chemical concept in a structure and detailed manner. Until now, chemistry lessons are still a big challenge for teachers, because students often experience difficulties when learning chemical concept such as the concept of stoichiometry. This study aims to determine the level of concept understanding and the percentage of students' concept understanding on stoichiometry material using a five tier diagnostic test. The method used in this research is descriptive qualitative. The results showed: (1) the average level of students'

Even though physical experiments are mandatory in science education, there has been an increasing demand for virtual experiments. This research aimed to investigate the impact of virtual experiments compared to physical experiments on students’ conceptual understanding of chemical kinetics concepts. To achieve this, a two-phase explanatory sequential mixed method approach was employed to collect and analyze quantitative and qualitative data. One group of students conducted virtual experiments (n = 25), while another group of students practiced the same topic with physical experiments (n = 26).

Abstract:
Abstract The nickel alloys for the modern chemical process and petrochemical industries not only have to resist uniform corrosion, localized corrosion and stress corrosion cracking as characterized by their alloy content, but they must essentially maintain these same corrosion resistance characteristics during manufacture, fabrication and assembly of various components used in these industries. The industry has experienced some costly mishaps and economic penalties due to premature failures of the component either during fabrication (cracking) or accelerated corrosion during service.

Abstract:
The integration of mixed reality (MR) and virtual reality (VR) into Chemical, Biochemical, and Biomolecular Engineering (CBB) education presents an opportunity to address one of today�s most pressing pedagogical challenges: sustaining student attention and engagement. Traditional �magistral� approaches often tend to limit the adoption of interactive methodologies. By contrast, MR/VR technologies can heighten immersion and practical intuition, capturing learner focus more effectively than conventional lectures. Yet, if deployed as superficial, isolated demonstrations, these tools may fail to su

Abstract:
Artificial intelligence (AI) and particularly generative AI led to recent breakthroughs, e.g., in generating text and images. There is also a potential of these technologies in chemical engineering, but the lack of structured big domain-relevant data hinders advancements. I envision an open Chemical Engineering Knowledge Graph (ChemEngKG) that provides big open and linked chemical process information. In this article, I present the concept of �flowsheet mining� as the first step towards the ChemEngKG. Flowsheet mining extracts process information from flowsheets and process descriptions found

Abstract:
Abstract Some achievements in corrosion inhibition of metals by organic compounds are considered on the basis of analysing the scientific publications during the last decade. The influence of chemical structure of organic compounds on inhibitor protection of various metals dissolving from the active state or undergoing localized corrosion is given special attention. The great importance of considering both the electronic and solvation effects as well as further development of the complex formation concept for better understanding of the inhibition process is emphasized.

Abstract:
Abstract H2S corrosion is controlled by processes occurring across the corrosion product (FeS) layer and by chemical effects which affect the properties of this layer. Laboratory data are reviewed which clearly demonstrate the parabolic nature of the corrosion kinetics. Along with the corrosion rates the film growth rates were experimentally determined. It was postulated that that the permeability was in essence the parabolic rate constant and could be calculated from the differential weight loss corrosion and the associated film weight. The permeability could then be examined as a function of

Abstract:
Abstract Galvele introduced a new quantitative framework for localized corrosion through his seminal paper on acidification and chloride accumulation in pits and the need for a critical product of current density and pit depth to sustain this local chemistry. This concept, introduced in 1976, holds good today, but has been enhanced by the ability to conduct more complex computations, better modeling of concentrated solutions that could be present in local areas, and the ability to perform in-situ chemical analyses in pits. The purpose of this paper is to review the progress in these areas with

Abstract:
The concept of entropy, a fundamental principle in the field of chemistry, has traditionally been oversimplified as a mere measure of disorder. However, this simplistic perspective fails to capture the intricate and multifaceted nature of entropy, along with its profound influence on various phenomena. This paper seeks to delve deeper into the understanding of entropy by moving beyond the conventional disorder-centric viewpoint and adopting a more nuanced approach that integrates both disorder and energy considerations.
