Towards a Sustainable Future: Challenges and Opportunities for Early-Career Chemists.

The concepts of sustainability and sustainable chemistry have attracted increasing attention in recent years, being of great importance to the younger generation. In this Viewpoint Article, we share how early-career chemists can contribute to the sustainable transformation of their discipline. We identify ways in which they can engage to catalyse action for change. This article does not attempt to answer questions about the most promising or pressing areas driving research and chemical innovation in the context of sustainability. Instead, we want to inspire and engage early-career chemists in pursuing sustainable actions by showcasing opportunities in education, outreach and policymaking, research culture and publishing, while highlighting existing challenges and the complexity of the topic. We want to empower early-career chemists by providing resources and ideas for engagement for a sustainable future globally. While the article focuses on students and early-career chemists, it provides insights to further stimulate the engagement of scientists from diverse backgrounds.

Evolving from academic to academic entrepreneur: overcoming barriers to scientific progress and finance.

The overall goal of my career as an academic chemist has always been the design and creation of advanced therapeutics and diagnostics that address unmet medical need in the management of chronic diseases. Realising this goal has been an immensely difficult process involving multidisciplinary problem-driven research at the chemistry-biology-medicine interfaces. With success in the laboratory, I started seriously to question the value of remaining an academic whose career is spent in the pursuit of knowledge and understanding alone without making any significant effort to translate knowledge and understanding gained into products of genuine utility for public benefit. Therefore, I elected by choice to become an academic entrepreneur, seeking opportunities wherever possible for the translation of the best of my personal and collaborative academic research work into potentially valuable and useful products. This choice has brought with it many unexpected difficulties and challenges. Nevertheless, progress bas been made and sufficient learnt to suggest that this would be an appropriate moment to take stock and provide some personal reflections on what it takes to design and create advanced therapeutics and diagnostics in the laboratory then seek to develop, innovate and translate the best towards market.

The Effects of Research & Development Funding on Scientific Productivity: Academic Chemistry, 1990-2009.

This article examines the relationship between Research & Development (R&D) funding and the production of knowledge by academic chemists. Using articles published, either raw counts or adjusted for quality, we find a strong, positive causal effect of funding on knowledge production. This effect is similar across subsets of universities, suggesting a relatively efficient allocation of R&D funds. Finally, we document a rapid acceleration in the rate at which chemical knowledge was produced in the late 1990s and early 2000s relative to the financial and human resources devoted to its production.

Chemical leasing in the context of sustainable chemistry.

Chemical leasing is a new and innovative approach of selling chemicals. It aims at reducing the risks emanating from hazardous substances and ensuring long-term economic success within a global system of producing and using chemicals. This paper explores how, through chemical leasing, the consumption of chemicals, energy, resources and the generation of related wastes can be reduced. It also analyses the substitution of hazardous chemicals as a tool to protect environmental, health and safety and hence ensure compliance with sustainability criteria. For this, we are proposing an evaluation methodology that seeks to provide an answer to the following research questions: (1) Does the application of chemical leasing promote sustainability in comparison to an existing chemicals production and management system? 2. If various chemical leasing project types are envisaged, which is the most promising in terms of sustainability? The proposed methodology includes a number of basic goals and sub-goals to assess the sustainability for eight different chemical leasing case studies that have been implemented both at the local and the national levels. The assessment is limited to the relative assessment of specific case studies and allows the comparisons of different projects in terms of their relative contribution to sustainable chemistry. The findings of our assessment demonstrate that chemical leasing can be regarded as promoting sustainable chemistry in five case studies with certainty. However, on the grounds of our assessment, we cannot conclude with certainty that chemical leasing has equivalent contribution to sustainable chemistry in respect of three further case studies.

Making expensive dirhodium(II) catalysts cheaper: Rh(II) recycling methods.

Dirhodium(II) catalysts have been widely used as a remarkable tool in organic synthesis, ultimately resulting in a myriad of transformations and formation of a wide variety of compounds, every so often intermediaries in drug synthesis. Aiming at a more sustainable chemistry, several methods suitable for the reutilisation of expensive dirhodium complexes have been developed. Herein, we provide a combined overview of the available methods for recovering and reusing dirhodium(II) metal complexes in catalysis, covering homogeneous catalysis as well as heterogenisation methods.

The survival of 19th-century scientific optimism: the public discourse on science in Belgium in the aftermath of the Great War (ca. 1919-1930).

In historiography there is a tendency to see the Great War as marking the end of scientific optimism and the period that followed the war as a time of discord. Connecting to current (inter)national historiographical debate on the question of whether the First World War meant a disruption from the pre-war period or not, this article strives to prove that faith in scientific progress still prevailed in the 1920s. This is shown through the use of Belgium as a case study, which suggests that the generally adopted cultural pessimism in the post-war years did not apply to the public rhetoric of science in this country. Diverse actors -- scientists, industrialists, politicians, the public opinion, and the military staff -- declared a confidence in science, enhanced by wartime results. Furthermore, belief in science in Belgium was not affected by public outcry over the use of mustard gas, unlike in the former belligerent countries where the gas became an unpleasant reminder of how science was used during the war. Even German science with its industrial applications remained the norm after 1918. In fact, the faith in science exhibited during the pre-war years continued to exist, at least until the 1920s, despite anti-German sentiments being voiced by many sections of Belgian society in the immediate aftermath of the war.

[The pharmaceutical industry in the industrial chemical group: the National Union of Chemical-Pharmaceutical Laboratories (1919-1936)]. / La industria del medicamento en el seno del colectivo químico industrial: La Unión Nacional de Laboratorios Químico-Farmacéuticos (1919-1936).

The pharmaceutical industry associations, as it happened with other businesses, had a significant rise during the dictatorship of Primo de Rivera and II Republic. The 'Cámara Nacional de Industrias Químicas', in Barcelona, represented the national chemical industry to its ultimate assimilation by the 'Organización Sindical' in 1939. In this association, matters relating to pharmaceutical products -- which we will especially deal with in this work -- were managed by the 'Unión Nacional de Laboratorios Químico-Farmacéuticos', which defended the interests of pharmaceutical companies in the presence of government authorities, using the resources and mechanisms also managed by business pressure groups. The inclusion of industrial pharmacy in the Chemical lobby separated the pharmaceutical industry from traditional exercise and its corporate environment. this created ups and downs, conflicts of interests and finally, love and hate relationships with their colleagues of the pharmacy work placement and, of course, with the association that represented them: the 'Unión Farmacéutica Nacional'.

Trimethylsilyldiazomethane: a safe non-explosive, cost effective and less-toxic reagent for phenol derivatization in GC applications.

Diazomethane is a highly explosive and toxic gas routinely employed for the quantitative and clean derivatization of phenols. We investigated the commercially available trimethylsilyldiazomethane in the presence of diisopropylethylamine as a safe, non-explosive and less-toxic alternative using six phenolic polychlorinated biphenyls as model analytes and fluoro-tagged analogues as internal standards. We compared yields and derivatization times of each method employing a liver microsomal extract as a real matrix. Steric hindrance and electronic properties of the analytes were also investigated. The alternative method afforded equal to higher derivatization yields with increased reaction times, up to 100 min, while explosion and toxic exposure risks were minimized and cost efficiency was increased above 25%. These findings demonstrate that non-explosive trimethylsilyl diazomethane produces comparable derivatization results to the dangerous diazomethane under the conditions studied.
