Visual demonstration of the ionic strength effect in the classroom: the Debye-Hückel limiting law

The effects of ionic strength on ions in aqueous solutions are quite relevant, especially for biochemical systems, in which proteins and amino acids are involved. The teaching of this topic and more specifically, the Debye-Hückel limiting law, is central in chemistry undergraduate courses. In this work, we present a description of an experimental procedure based on the color change of aqueous solutions of bromocresol green (BCG), driven by addition of electrolyte. The contribution of charge product (z+|z-|) to the Debye-Hückel limiting law is demonstrated when the effects of NaCl and Na2SO4 on the color of BCG solutions are compared.

A política de inovação e a formação do químico

In December 2004, Brazil's President signed Law number 10.973, which provides for incentives toward innovation, scientific and technological research in the production environment and other measures, also known as the Law of Innovation. Although Brazil has advanced greatly in the number of scientific articles published, currently accounting for about 3% of world scientific output, this progress has not been replicated in the production of patents. This article presents a discussion on the importance of introducing patent issues into national undergraduate courses.

Físico-química experimental: uma proposta para abordar equilíbrio de fases em sistemas ternários

On undergraduate courses, practical classes represent periods in which students can verify the concepts presented in theoretical classes. Conversely, the teaching internship in graduate programs allows these students to incorporate pedagogical practices into their experience, predominantly involving observation and reproduction of methods adopted by supervisors. We propose internship teaching as a period for reflection on our pedagogical practice and present a methodology for an experimental physical chemistry classroom. The students can interact with the experiment and instructor, furthering the study of ternary systems while developing their skills for investigative work.

Desafios da indústria farmacêutica brasileira

The paper traces a panorama of the development of new drugs and hopes to contribute for Brazil to become a player in the discovery of new drugs. Brazil is the sixth world market retail consumer of medicines prone to expansion, has a pharmaceutical industry focused on the production of generics and a very large number of undergraduate courses in Pharmacy. The national industry has grown over the last decade after the Generics Act 9787/99. Despite these positive aspects, a number of bottlenecks prevent Brazilian pharmaceutical industry to invest in the development of new drugs. There are, however, a number of initiatives to reduce the dependence on imported generic drugs. It is a very good start for the development of new pharmaceutical drugs.

Experimento utilizando grãos para explorar a calibração em análises químicas

The conventional curriculum of Analytical Chemistry undergraduate courses emphasizes the introduction of techniques, methods and procedures used for instrumental analysis. All these concepts must be integrated into a sound conceptual framework to allow students to make appropriate decisions. Method calibration is one of the most critical parameters that has to be grasped since most analytical techniques depend on it for quantitative analysis. The conceptual understanding of calibration is not trivial for undergraduate students. External calibration is widely discussed during instrumental analysis courses. However, the understanding of the limitations of external calibration to correct some systematic errors is not directly derived from laboratory examples. The conceptual understanding of other calibration methods (standard addition, matrix matching, and internal standard) is imperative. The aim of this work is to present a simple experiment using grains (beans, corn and chickpeas) to explore different types of calibration methods.

PREPARAÇÃO DE PONTOS DE CARBONO E SUA CARACTERIZAÇÃO ÓPTICA: UM EXPERIMENTO PARA INTRODUZIR NANOCIÊNCIA NA GRADUAÇÃO

Carbon dots (CDs) constitute a new class of carbon-based nanomaterials that measure less than 10 nm and display attractive physical and chemical features such as fluorescence. CDs have been considered the new “power” carbon nanomaterials since their accidental discovery in 2004. This study reports a simple, easy, and accessible experiment for undergraduate courses. The experiment involves the preparation of CDs by pyrolysis using commercial gelatin as a low cost precursor as well as CD purification and optical characterization. The optical properties of CDs such as absorption and emission properties make them a promising material for teaching the basic concepts and techniques used for characterization of nanomaterials. Also, the reactants and final product are suitable for undergraduate courses since they are non-toxic materials. The prepared CDs can be used in such applications as bioimaging, solar cells, and photocatalysis.

PROPOSTA EXPERIMENTAL DIDÁTICA PARA O ENSINO DE ANÁLISE DE COMPONENTES PRINCIPAIS

Principal component analysis (PCA) is a chemometric method that allows for the extraction of chemical information that would otherwise be impossible to determine. Teaching chemometrics to undergraduates can contribute to the overall professional development and training of new teachers, whose profiles have been gaining attention due to the current demand for data interpretation. In this study, a didactic experiment involving PCA is proposed. Spectrophotometry was used in the ultraviolet-visible (UV-Vis) region to assess the behavior of anthocyanins extracted from red cabbage at different pH values. The results suggest the possible separation of anthocyanin structures into three distinct groups, according to their chemical characteristics displayed in acid, neutral, and basic media. The objective is to develop educational materials targeted to undergraduate courses, which encompass a larger number of concepts and introduce instrumental techniques currently being employed in both academic research and the industrial sector. Specifically, the proposed experiment introduces concepts related to spectrophotometry in the UV-Vis range and the PCA chemometric method. The materials used are easily accessible, and UV-Vis spectroscopy equipment is less expensive in comparison with other spectroscopy methods.

Burgoyne Centre for Entrepreneurship fonds

An Entrepreneurship Centre was established at Brock University in 1988 as a joint venture between the University and the City of St. Catharines. In Januaray 1989, a generous donation was made to the Centre by the Burgoyne family, proprietors of the St. Catharines Standard. The Centre subsequently became known as the Burgoyne Centre for Entrepreneurship (BCE). The Centre’s mission was to “promote excellence in research, education and training for entrepreneur development and new venture creation”. To achieve this objective, it was necessary for the BCE to become a community focal point and serve as a link between academic, private and government sectors in the Niagara Region that were involved in entrepreneurial activities. This was primarily done with the provision of educational programs offered through cooperating organizations. Funding for the Centre came from multiple sources, including fees for services and contract research, endowments and grants, as well as Brock University. An Advisory Council, composed of local prominent businesspeople and chaired by Henry Burgoyne, assisted the Centre with promotion and fundraising. The partnerships established by the BCE with other community bodies such as the Lincoln County Board of Education and the Niagara Region Development Corporation resulted in important collaborative community initiatives such as the Niagara Enterprise Agency and the New Enterprise Store. Such collaborations increased the Centre’s profile without duplicating or competing with services offered by existing agencies. The BCE was also instrumental in establishing an entrepreneurship curriculum for secondary school students, and collaborated with the Faculty of Education at Brock University to offer an Ontario Secondary School Entrepreneurship Specialist Teaching Certificate Program to teachers. As the BCE became more prolific in the community, and the iniatives it fostered in the community began to thrive, the Centre’s leadership required the authority to make instantaneous decisions. This was at odds with the hierarchical structure of the University, to which the BCE was accountable. Ultimately, this situation led to the demise of the Centre. The university focused its efforts on academic research and undergraduate courses, while the community partners took responsibility for any joint programs.

Innovating in Teaching Collaborative Practice with a Large Student Cohort at Université de Montréal

Université de Montréal implemented an interprofessional education (IPE) curriculum on collaborative practice in a large cohort of students (>1,100) from 10 health sciences and psychosocial sciences training programs. It is made up of three one-credit undergraduate courses (CSS1900, CSS2900, CSS3900) spanning the first 3 years of training. The course content and activities aim for development of the six competency domains identified by the Canadian Interprofessional Health Collaborative. This paper describes the IPE curriculum and highlights the features contributing to its success and originality. Among main success key factors were: administrative cooperation among participating faculties, educators eager to develop innovative approaches, extensive use of clinical situations conducive to knowledge and skill application, strong logistic support, close cooperation with health care delivery organizations, and partnership between clinicians and patients. A distinguishing feature of this IPE curriculum is the concept of partnership in care between the patient and caregivers. Patients’ representatives were involved in course planning, and patients were trained to become patients-as-trainers (PT) and cofacilitate interprofessional discussion workshops. They give feed- back to students regarding integration and application of the patient partnership concept from a patient’s point of view.

Dimensões do êxito de egressos de escolas públicas no processo seletivo para o cursos de medicina da UFPE

Garantir a oferta de uma educação de qualidade nas escolas públicas de estados e municípios é um grande desafio a ser enfrentado pelo Brasil. Em se tratando da aprovação nos vestibulares para cursos superiores prestigiados socialmente, o êxito de egressos dessas instituições é difícil em qualquer universidade. Esta investigação, de natureza qualitativa articula dados quantitativos para fundamentar as discussões acerca dos fatores que explicam a aprovação desses estudantes no processo seletivo para o curso de medicina da Universidade Federal de Pernambuco [UFPE]. A fim de se realizar o estudo de caso em questão, utilizamos três instrumentos de recolha: o questionário, contendo informações pessoais e dados da formação educacional dos três egressos e de seus familiares; a entrevista semiestruturada, onde os três estudantes e seus pais tiveram a possibilidade de discorrer sobre os temas propostos; e a história de vida, através da qual um dos sujeitos retratou todo o conjunto da experiência vivida. Todo o material foi comparado e relacionado durante a análise por meio da triangulação de dados. Os nossos resultados confirmam os achados de outros trabalhos do gênero quando apontam que melhorar a qualidade da Educação Básica é essencial para que o Brasil avance na formação de mão de obra, mas, diferencia-se de alguns deles, quando sugere que, em relação aos candidatos que tentam ingressar no curso de medicina, tão importantes quanto o interesse e a mobilização do estudante e de seus pais em relação aos estudos são os investimentos em serviços de apoio pedagógico e psicológico, tanto aqueles prestados pelas escolas quanto os que são realizados em locais especializados [dependendo do caso].

Forensic students are getting their hands dirty

Final year research projects are an important part of undergraduate chemistry courses, allowing students to enhance transferable skills in teamworking, problem solving and presentations, at the same time as learning valuable practical skills. Several recent reports have highlighted the importance of research based studies as part of undergraduate courses. ‘We need to encourage universities to explore new models of curriculum. They should all incorporate research based study for undergraduates to cultivate awareness of research careers, to train students in research skills for employment, and to sustain the advantages of a research teaching connection,’ wrote Paul Ramsden from James Cook University, Australia, in a 2008 report for the UK’s Higher Education Academy.1 A 2010 report published by the Biopharma Skills Consortium – that promotes collaboration across the higher education sector in the area of biopharma – also stated that: ‘Companies seek recruits well placed to acclimatise quickly to the work environment. They are looking for recruits who can deploy a range of generic skills in the application of their knowledge.’2
