A series of small-scale/micro-scale experiments used for the education of undergraduate students in chemical engineering courses have been developed. Based on the “small-scale/micro-scale” concept, the experiments were developed to provide an intuitive understanding of chemical processes, both by increasing the visibility of these chemical processes and by making the apparatus compact (desktop size). Nine experiments were developed that are relevant to the fields of thermal engineering, fluid engineering, unit operations, and reaction engineering. These experiments were introduced during the educational experiment course for undergraduates in the chemical engineering program.

Future Research Directions

In the last two decades, scientific methodologies for the prediction of the design, performance and classification of fragrance mixtures have been developed at the Laboratory of Separation and Reaction Engineering. This review intends to give an overview of such developments. It all started with the question: what do we smell? The Perfumery Ternary Diagram enables us to determine the dominant odor for each perfume composition. Evaporation and 1D diffusion model is analyzed based on vapor-liquid equilibrium and Fick’s law for diffusion giving access to perfume performance parameters. The effect of matrix and skin is addressed and the trail of perfumes analyzed. Classification of perfumes with the perfumery radar is discussed. The methodology is extended to flavor and taste engineering. Finally, future research directions are suggested.

Drying Efficiency

The most used biomass are wood, sugar cane, paper, rice husk, and peanut. Based on the concept of sustainability and waste reduction, the full utilization of biomass is an alternative capable of providing people with a better nutritional intake, improving the economy related to biomass and the ecological relationship between man and the environment. So, the aim of this work was the sustainable use the biomass, the peanut, through multiple unit operations. Thus, the material went through several processes as the grinding process, where it was possible to obtain immediate analysis data (moisture content, ash content, volatile content and fixed carbon) and particle size. Then, drying was performed employing solar energy and the drying efficiency was obtained. Infrared and greenhouse tests were performed in the laboratory to determine the drying and humidity curves. After drying, it was also carried out the oil extraction using ethanol as solvent heated by solar energy. After that, the residual cake was used as the adsorbent material in the dye removal by adsorption in a fixed bed. So, the dye-impregnated adsorbent has undergone a process of pyrolysis in order to form fine coal, bio-oil, and gases. With products and by-products of each process, it was possible to generate the infrared spectrum of each. Therefore, it is shown how the integral use of peanut as biomass is possible, using chemical engineering sustainable processes, and how it may contribute to the reduction of the pollution and to the reduction of waste production.

Production Objectives

Process intensification (PI) is currently one of the most significant trends in chemical engineering and process technology. PI is a strategy of making dramatic reductions in the size of unit operations within chemical plants, in order to achieve production objectives. PI technology is able to change dramatically the whole chemical engineering industry pathway to a faster, cleaner and safer industry. Nonetheless, PI technology will be handicapped if such system is not properly controlled. There are some foreseeable problems in order to control such processes for instance, dynamic interaction between components that make up a control loop, response time of the instrumentations, availability of proper sensor and etc. This paper offers an overview and discussion on identifying potential problems of controlling intensified systems.

Bookworms as information literacy? How Henri Lefebvre's spatial triad encouraged OCAD University to re-place the art library through site-interventions

Does the art library need re-placing? Using the commentary of an OCAD University faculty member concerning “a perception issue with the library and its use,” librarian Daniel Payne uses theorist Henri Lefebvre's spatial triad to decode, in general terms, undergraduate students’ understanding of libraries as articulated in the OCLC Perceptions of libraries surveys. In an attempt to re-align concepts of the library as place at OCAD University, an exhibition review interpretation of student site-interventions demonstrates how visual communication can offer more insightful “spatial practices” for both students and library staff. In the process, librarians were challenged to accommodate student creative voices that pushed both policy boundaries and comfort zones. Although a small-scale information literacy initiative in which no formal quantitative data was collected, the ability of having conceptual models of librarians interact and even clash with those of students helped realign both stakeholders’ understandings of libraries as complex spatial entities.

Allosteric function is a critical component of many of the parts used to construct gene networks throughout synthetic biology. In this review, we discuss an emerging field of research and education, biomolecular systems engineering, that expands on the synthetic biology edifice—integrating workflows and strategies from protein engineering, chemical engineering, electrical engineering, and computer science principles. We focus on the role of engineered allosteric communication as it relates to transcriptional gene regulators—i.e., transcription factors and corresponding unit operations. In this review, we ( a) explore allosteric communication in the lactose repressor LacI topology, ( b) demonstrate how to leverage this understanding of allostery in the LacI system to engineer non-natural BUFFER and NOT logical operations, ( c) illustrate how engineering workflows can be used to confer alternate allosteric functions in disparate systems that share the LacI topology, and ( d) demonstrate how fundamental unit operations can be directed to form combinational logical operations. Expected final online publication date for the Annual Review of Biophysics, Volume 50 is May 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
