What Are Chemical Engineering and Biomolecular Engineering?

The minimum requirement to become a chemical engineer is the completion of a four-year bachelor’s degree (BS) at a college or university. There are well over 100 ABET-accredited (Accreditation Board for Engineering and Technology) programs in chemical engineering in the United States.1 Advanced degrees, such as an MS (Master of Science or Master of Engineering, which typically requires an additional two years of school following an undergraduate degree), or a PhD (Doctor of Philosophy, which typically requires an additional four years of school following an undergraduate degree) provide additional qualifications that offer advantages in roles in process and product technology, research, development, and engineering. Students seeking these advanced degrees often benefit from working in industry for several years after the bachelor’s degree before returning to the university for graduate school.
Enabling Circumstances: Women Chemical Engineers at the Norwegian Institute of Technology, 1910–1943
Published in Ambix, 2022
From 1936 to 1938, Stene (Sørensen from 1936) worked as a chemical engineer at the Nidar Chocolate Factory in Trondheim. The factory had been established in 1912, had begun production three years later, and it is still in operation. The foodstuff industry was among the branches that regularly attracted the first ten generations of chemical engineers enrolled at NTH, in addition to the electrochemical industry and the pulp and paper industry. However, although Nidar experienced growth in the first decade, like other branches of industry, chocolate producers struggled in the 1920s. In addition to consumers’ lack of means to buy luxury goods, a special chocolate tax was introduced in 1922, which further worsened the situation. As much as 30% of the cost of chocolate was added as a tax to increase the states’ finances. Many other taxes were introduced during the same period. Reduced sales of products led to hard competition among chocolate producers, and in 1929, new share capital had to be introduced at Nidar to avoid bankruptcy. Nevertheless, the 1930s—when Stene Sørensen was working at Nidar—have been characterised as the most innovative period in the factory’s history.78 One of the products that was developed during this period was Stratos, a porous chocolate that remains popular today.79 Stene Sørensen was among the engineers who developed the Stratos chocolate bar (Figure 6).
A mathematics teacher’s specialized knowledge in the selection and deployment of examples for teaching sequences

Our informant was a state school teacher who had originally trained as a chemical engineer. With some 35 years in the profession, he amply met Chi’s (2011) criteria for being considered a teacher of expertise. In the course of his career, he had taught not only Mathematics, but also Physics, Chemistry, Technology and Geology, thus marking him as an a priori candidate for illustrating the use of tangible examples. The examples which were selected for analysis derived from a third-year secondary lesson (14–15-year-old students) which was given towards the end of the 2019/2020 academic year, in which the teacher had begun work on the concept of sequences with the intention of then moving on to arithmetic and geometric progressions.
George E. Davis: Editing the Chemical Trade Journal, 1887–1906
Published in Ambix, 2023
Under Keville Davis’s editorship the Chemical Trade Journal and Chemical Engineer continued successfully alongside The Chemical News and the Journal for the Society of Chemical Industry until 1922. In December 1922, a British professional body to represent the interests of chemical engineers was formed as the Institution of Chemical Engineers (IChemE) and the following year the IChemE began publishing an annual journal, Transactions of the Institution of Chemical Engineers.60 The new journal became a direct competitor to the Chemical Trade Journal and Chemical Engineer which ceased publication in 1933.
