What Are Employers Looking For When Hiring Separation Scientists?

Per the U.S. National Academies of Science (NAS) 2019 report “A Research Agenda for Transforming Separation Science,” the number of America’s academic positions in separation science has decreased considerably in recent years, with a number of universities choosing to stop hiring faculty in this area. Specifically, since 1987 (the year of the previous NAS report on this field), the number of faculty members readily identifiable as “separations researchers” has dropped by 40% in the top chemistry departments, and by 30% in the top chemical engineering departments. At the same time, national government funding organizations (such as the National Science Foundation [NSF]) have significantly reduced funding for separation science. All this occurs despite the continuing demand for separation scientists and engineers in the largest economic sectors of the United States. LCGC North America spoke to Caroline McGregor and Justin Pennington of Merck Research Laboratories regarding the effects of the aforementioned occurrences on their firm’s hiring practices, and what employers in general are looking for in candidates they are considering for open separation scientist positions.

Automated quality analysis in continuous downstream processes for small-scale applications

Development of integrated, continuous biomanufacturing (ICB) processes brings along the challenge of streamlining the acquisition of data that can be used for process monitoring, product quality testing and process control. Manually performing sample acquisition, preparation, and analysis during process and product development on ICB platforms requires time and labor that diverts attention from the development itself. It also introduces variability in terms of human error in the handling of samples. To address this, a platform for automatic sampling, sample preparation and analysis for use in small-scale biopharmaceutical downstream processes was developed. The automatic quality analysis system (QAS) consisted of an ÄKTA Explorer chromatography system for sample retrieval, storage, and preparation, as well as an Agilent 1260 Infinity II analytical HPLC system for analysis. The ÄKTA Explorer system was fitted with a superloop in which samples could be stored, conditioned, and diluted before being sent to the injection loop of the Agilent system. The Python-based software Orbit, developed at the department of chemical engineering at Lund university, was used to control and create a communication framework for the systems.To demonstrate the QAS in action, a continuous capture chromatography process utilizing periodic counter-current chromatography was set up on an ÄKTA Pure chromatography system to purify the clarified harvest from a bioreactor for monoclonal antibody production. The QAS was connected to the process to collect two types of samples: 1) the bioreactor supernatant and 2) the product pool from the capture chromatography. Once collected, the samples were conditioned and diluted in the superloop before being sent to the Agilent system, where both aggregate content and charge variant composition were determined using size-exclusion and ion-exchange chromatography, respectively. The QAS was successfully implemented during a continuous run of the capture process, enabling the acquisition of process data with consistent quality and without human intervention, clearing the path for automated process monitoring and data-based control.

Overvıew of Bıoleachıng

Aims: This study aims to present a comprehensive analysis of bioleaching, the fundamental idea behind it, the emergence of microbes and the bioleaching approaches.
 Study Design: To do this, this research has been developed on a foundation of significant topics. The researcher used a quantitative approach in this particular investigation. The quantitative study is presented in tables that list the bioleaching processes and efficient microorganisms.
 Place and Duration of Study: This study was carried out in Chemical Engineering department, Delta State University of Science and Technology, Ozoro, Nigeria.
 Methodology: The researcher decided on a combination methodology because of the context of the present investigation. The approach of data collection and analysis employing qualitative as well as quantitative methodologies is known as combined research design.
 Results: The lengthy training period of microorganisms at the laboratory scale, which is significantly impacted by other experimental variables, is one of the key difficulties faced by the bioleaching process. Therefore, the key to increasing the simplicity of bioleaching technologies in large-scale industrial production is to enhance the bioleaching microorganism’s currently in use so that they can continue to be highly active under more complicated reaction conditions. Regarding the microbial problem, biological leaching piles of just a few genes in the offspring of acidophilic microorganisms have been documented. Although some bacterial genomes from acid mine drainage and acidic environments have been used to create replacements, these models cannot fully depict the potential for leaching; in addition, it can be difficult for researchers to obtain samples of microbes from actual production, making further research challenging.
 Conclusion: In the years to come, microbial use for waste treatment and mineral processing will continue to gain importance on a global scale. The need to process ores with trace amounts of copper and gold, the potential for recycling waste spoils and tailings, financial limitations, and potential legislative changes on the environmental impact of more conventional approaches like hydrometallurgy will all contribute to this. The employment of chemolithotrophic and heterotrophic bacteria will be a significant addition, boosting the leaching rates and metal recoveries and enabling the treatment of resistant ores like chalcopyrite.

An institutional modernization project in chemical engineering education in Brazil: Developing broader competencies for societal challenges

Contemporary societal challenges put in evidence the need to improve the hard and soft skills of chemical engineering students. To promote a more student-centered approach, active-based learning, and improved assessment strategies, the Brazilian government approved the so-called New National Curriculum Guidelines (NCG) for engineering courses. To comply with those guidelines, the Department of Chemical Engineering of the Polytechnic School of the University of São Paulo (USP) is currently developing an educational modernization process sponsored by the Fulbright Commission in Brazil, called Special Program for Modernization of Undergraduate Education (PMG). The project is based on three pillars of modernization: content (what), form (how), and infrastructure (where). This paper describes initiatives in each of those pillars: content and format changes in Chemical Reaction Engineering and Process Safety courses and the creation of new spaces for a student-centered approach (an innovative classroom layout and a makerspace). By gathering two concrete classroom experiences guided by a broader institutional educational policies (the PMG project and the NCG), this paper highlights that slight changes can lead to great improvements in the learning process, leading to more engagement in the development of hard skills while favoring improvements in soft skills, such as communication, team-based work, and critical thinking.

Reflection on Experiences of First-Year Engineering Students with Blended Flipped Classroom Online Learning during the COVID-19 Pandemic: A Case Study of the Mathematics Course in the Extended Curriculum Program

The shift to remote learning during the COVID-19 pandemic presented a unique challenge for higher education in developing countries such as South Africa, where resources are distributed unevenly. The Department of Chemical Engineering at a South African university of technology used a flipped classroom blended online learning approach in an engineering mathematics course. This study describes the transition of first-year engineering students from face-to-face learning to flipped classroom blended online learning. The Laurillard conversational framework for teaching learning was used to develop the five components of blended learning pedagogy, this allows students to discover, learn, practice, collaborate, and assess (DLPCA). The chosen assessment strategies made use of adaptive learning technology via the WebAssign platform to provide formative and summative assessments as well as timely feedback to each student. The authors examined the remote teaching and learning approach using three indicators: (i) learning—students’ learning experiences; (ii) assessment—students’ academic performance and integrity; and (iii) students’ challenges. The findings had a positive impact on students’ learning and performance in the mathematics course. The limitation to the study was that the data were collected only from one university of technology and were not compared with other universities in the country. The overall findings of this study indicate that students require time to adjust to online pedagogy to ensure a smooth transition.

Preparation and Characterization of Cellulose Nanoparticles from Agricultural Wastes and Their Application in Polymer Composites

, Page no - | ABSTRACT | PDF | FULL TEXT | e-PUB Background: The development of innovative eco-sustainable bio-nano-composites materials based on cellulose nanomaterials obtained from agricultural waste such as rapeseed plant straw and polymeric materials with improved properties. At first, cellulose was extracted from rapeseed plant straw and cellulosic and no cellulosic materials were estimated. It was found that the rapeseed plant straw contained about 43.48 wt.% cellulosic materials and 56.52 wt.% no cellulosic materials. It was also found that the rapeseed plant straw content about 34.84 wt.% α- cellulose. Then, nano-cellulose was prepared by acid hydrolysis of α -cellulose obtained from rapeseed plant straw. Poly vinyl acetate (PVAc) was prepared by soap free emulsion polymerization of vinyl monomer. Natural rubber (NR) collected as latex was oxidized by KMnO4. Blends of NR and oxidized NR with PVAc of different compositions such as NR60/PVAc40, NR40/PVAc60, ONR60/PVAc40, ONR40/PVAc60 were prepared by mixing NR latex and PVAc emulsion and followed by drying in an oven at 60°C. Composites of NR60/PVAc40 and ONR60/PVAc40 reinforced nano-cellulose (NC) were also prepared in similar way. The blends and composites were then characterized by FTIR, SEM, and Tensile test (TS). FTIR analysis confirmed the oxidation of NR and shown the variation of the functional groups in the blends and composites compared with the FTIR spectrum of NR, ONR and PVAc. SEM study exhibited that the nano-cellulose were dispersed within NR/PVAc and ONR/PVAc blends matrices with a little agglomeration. The tensile test results showed that the strength in composites was increased due to the reinforcing effect of nano-cellulose (NC). Objectives: The aim of this study is to assess the Preparation and characterization of binary blends of NR and oxidized NR with PVAc. Methods: This is an observational study. The study used to be carried out in the admitted patient’s Department of Applied Chemistry and Chemical Engineering, Islamic University, Kushtia-7003, Bangladesh. The duration of the period from Data was entered in MS Excel and Statistical analysis was done using SPSS trial version. Results: This study shows that the according to Constituent, Cellulose was 43.4822%, Alpha-Cellulose were 34.8427% and Cellulose were 8.6395%. And according to Source, Rice Straw were 32.15% %, Sugarcane were 41-43%, Rye Straw were 31.8-42.64%, Corn Stalks were 29.80% and Wheat Straw were 34-40%. Conclusion: Novel eco-friendly bio-nano-composites substances primarily based on renewable and sustainable assets namely natural rubber (NR) and nano-cellulose received from rapeseed plant straw as properly as poly vinyl acetate (PVAc) have been developed. In order to enhance the interfacial interactions amongst the composite factors such as NR, PVAc and NC, oxidation of the NR latex was once carried out by way of KMnO4 before blending mixing with PVAc emulsion and NC suspension.

Identification of Mercury Emissions in Soot with the Quadrant Method on Combustion of Gold in Aceh Jaya District

BACKGROUND: Gold mining, especially by the community, causes many problems. One of the problems is the increase in mercury pollution. The amalgamation technique involving mercury in the gold processing process is still widely used by miners and has the potential to threaten the health of workers and the surrounding community. AIM: This study aimed to identify mercury levels in soot at the location of a traditional gold processing plant in Paya Seumantok Village, Krueng Sabee District, Aceh Jaya District. METHODS: This research was conducted at the Environmental Quality Analysis laboratory, Chemical Engineering Department, Syiah Kuala University, Banda Aceh, in May–August 2021. The sample in this study was soot caught on cloth attached to the gold kiln location by amalgamation using the quadrant method. The soot sample was obtained from the people’s gold processing unit in Gampong Paya Seumantok, Krueng Seabee District; then, the fabric sample containing soot was destroyed using HNO3 in the microwave. Measurement of mercury levels, using AAS Perkin-Elmer Analyst 600, equipped with Graphite Furnace (AAS) Technique. RESULTS: The results of the identification show that the mercury level in the first stage of measurement found the highest mercury concentration at a distance of 10 cm with a concentration of 41.90 (±21.64) g-Hg/g, a distance of 5 cm was obtained at 28.71 (±11. 0.98) g-Hg/g, and at a distance of 15 cm obtained 28.20 (±2.85) g-Hg/g. Furthermore, in the measurement of samples in stages 2 and 3, the mercury concentration in soot is influenced by distance, where the closer the distance, the higher the mercury concentration. Stage 2 measurement at a distance of 5 cm, the mercury concentration obtained is 26.84 (±21.05) g-Hg/g, a distance of 10 and 15 cm each has a concentration of 9.25 (±1.26) g-Hg/g and 9.91 (±3.59) g-Hg/g, and in the third stage of the test, the highest concentration located at a distance of 5 cm with a concentration of 20.27 (±3.57) g-Hg/g. CONCLUSION: The average value of mercury concentration in soot obtained far exceeds the threshold set by the World Health Organization, which is 1 g-Hg/gram. Mercury levels that have exceeded the threshold need to be filtered in an enclosed space before the smoke from burning gold spreads into the free air.

Manure Waste Management to Produce and Utilize Biogas Efficiently and Effectively in a Smart Eco-Social Village in Bandung

The river is one of the primary sources of fresh water. It serves purposes for irrigation systems in agriculture, fulfilling domestic needs (water drinking, washing), transportation medium, energy production, and leisure. In West Bandung, the Cikapundung River becomes the source of life to sustain the population. More than 50% of the population upstream Cikapundung lives as agriculture and dairy farmers. Unfortunately, due to those activities, the river condition is considered unhealthy. Agriculture and dairy farmers discharge their wastes into the river instead of employing them for biogas, despite biogas's role in ensuring farming sustainability. Thus, Chemical Engineering Department and Student Society (HMPSTK) of Parahyangan Catholic University (UNPAR) constructed a system involving biodigester to produce biogas from agricultural waste (cow manure and organic waste) as a prototype solution for this issue. The community service program was divided into seven stages: a) Problem identification, b) Location survey and advocacy, c) Sample collection, d) Research, e) Construction of a biogas digester, f) Socialization with the local community, and g) Follow-up of the outcomes. In fact, a 5,000 Liter of fiberglass bio-digester was successfully installed in Cibodas Village, Maribaya, Lembang, with the help of PRIMARY (Program Biogas Rumah), a local biogas contractor. The mixture of livestock manures and organic waste of a 3:1 ratio produced the largest biogas volume. Biogas generated from biodigester was applied for cooking and lighting kerosene lamps. The result showed that no leakage was observed until 3-years of installation of the biodigester. However, it is suggested that a continuous and solid system involving multiple ways of manure processing such as the biogas and vermicompost production as well as the biogas utilization should be designed to encourage not only a eco-friendly solution but also to initiate a circular economy model in the community. Thus, it will be a sustainable solution not only for overcoming the largest issue of Cikapundung Rivers's organic waste disposal but also for the other agriculture and farming in Indonesia.
