Could you briefly explain the focus of your article to the non-specialist (in one or two sentences only) and why it is of current interest?
The focus of the article is the computational investigation of SN2 reactions in organic molecules which contain both phosphorus and chlorine atoms.
The SN2 reaction mechanism was discovered in the 1930’s by scientists Hughes and Ingold, and since then has been used in a number of syntheses; however, it is still of current interest as new aspects of this mechanism, at the molecular level, are still being discovered. These aspects include new sites of nucleophilic attack which are not immediately chemically intuitive.
How big an impact could your results potentially have?
In textbooks, SN2 reactions are defined in a firm way, often taking the example of SN2 at the carbon atom, detailing hill-shaped potential energy surfaces and nucleophilic attack at one specific atom centre. However, our research indicates that these well-established facts may change. Potential energy surfaces may take the shape of single, double or triple wells or a combination of hill and well shapes. The most preferred site of nucleophilic attack may change according to what neighbouring groups are present in the molecule of interest. It is important to include and try to explain these differences in chemistry textbooks.
Could you explain the motivation behind this study?
The Computational Chemistry Group of the University of Mauritius (CCUoM) was set up in 2003 in the Department of Chemistry. Our interest has always been on the investigation of different aspects of reaction mechanisms. We have a programme to study SN2 reaction mechanisms, which resulted in two PhD graduates and several publications. We started by studying the effect of different nucleophiles. Another part of the programme involved studying SN2 reactions at different atoms within one molecule. This started in 2017, when we came across one experimental study which involved SN2 at the phosphorus atom. We tried to explain the results of this experimental study using computational methods, which led us to discover SN2 at the chlorine atom.
In your opinion, what are the key design considerations for your study?
For SN2 reactions, the key design considerations involve the reactive atom centres, neighbouring groups, the solvent and the nucleophiles. These may be used to tune reactions to design molecules of interest.
Which part of the work towards this paper proved to be most challenging?
Working with bulky molecules was the most challenging part. Computations involving bulky molecules are demanding in terms of computational cost. It is often challenging to strike the right balance between computational cost and accuracy of results.
What aspect of your work are you most excited about at the moment?
When this research project started, it was about SN2 reactions at the phosphorus atom but along the research journey, we stumbled on the SN2 at the chlorine atom, which offers a new world of possibilities to investigate. The possibilities are what we are most excited about.
What is the next step? What work is planned?
Our next projects will involve changing key factors in the SN2 reaction mechanism involving the chlorine atom and determining the effect. We are considering changing the nucleophiles which we investigated, modifying the solvent system, and changing neighbouring groups. We are also considering investigating SN2 reactions at other reactive atoms, such as bromine and iodine.

Persistent organic pollutants (POPs) are harmful compounds resistant to biological, chemical and photolytic degradation. They are persistent in the environment especially in soils, sediments and air for several decades. Due to their toxicity, they pose a significant threat to animal, human and environmental health, as they accumulate in the fatty tissues of humans and animals. In humans, POPs have been linked to adverse health effects, such as alterations in the development of reproductive, endocrine, neurological, and immune behavior. In animals, they have caused disease and abnormalities, including certain types of birds, fish and mammals.
Dioxin-like compounds have been classified as POPs by the World Health Organization (WHO) and the US Environmental Protection Agency (USEPA) due to their hazardous properties including long shelf life, global distribution, accumulation and bioamplification in food chains; and its toxicological effects in humans, such as teratogenesis, tumor promotion, and modulation of the immune system. The POPs present in the environment have generated great interest within the scientific community due to their toxic effect, both for animal and human health.
Polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs) are compounds with similar chemical properties: they are organic solids, with high melting points and low vapor pressure, have extremely low solubility in water and are adsorbed strongly on particulate matter surfaces. Polychlorinated biphenyls (PCBs) are a group of organic chemical compounds that can cause a number of different adverse effects, and there are no known natural sources of PCBs in the environment. Although biphenyls are oily liquids or solids with an appearance that varies from colorless to light yellow, some PCBs are volatile and can exist as vapor in the air. PCBs have no known odor or taste, they enter the environment as mixtures containing a variety of individual components of polychlorinated biphenyls. They do not degrade easily and therefore remain for a long time, and can be easily detected in air, water and soil. Among the harmful effects they cause on human health, such as immune and neurological dysfunctions, they are also classified as possible human carcinogens and toxic in reproduction.
Currently, there are numerous gaps with respect to knowledge about these substances, in particular about methodologies for their detection and quantification, as well as about the levels that are potentially dangerous for humans. For this reason, the development, fine-tuning and validation of new methodologies that allow innovation and improvement of novel traceability systems for these compounds is of great interest. With the advent of sophisticated chromatography techniques, the development of innovative and alternative highly sensitive analytical methods for trace analysis of these compounds is a challenge.
Finally, it is of great importance to note that there are no laboratories in Argentina with analytical methodologies that detect and quantify these analytes, which is why they become so important and of great interest to study. In this way, it would allow to have the first bases for the quality control of products of agri-food origin for export and/or of the domestic market, and the great economic impact that it generates on their traceability.

Treatment for cancer and bacterial infections is challenging to approach due to various reasons such as the development of resistant and unwanted side effects. Development of new chemotherapeutic agents often ends up with a blunt end. Therefore, finding a new formulation and an effective delivery method for the currently available agents is a gold alternative.
Curcumin and zinc oxide nanoparticles (ZnO Nps) are such compounds that have enormous advantages. Of the potent bioactive metabolites that have been identified from plant sources, curcumin is one of the most-investigated safe chemical compounds. Research over the last two decades has shown it to be a potent anticancer and antimicrobial agent in cell- and animal studies. But inheritably, curcumin has low efficacy mainly due to the poor bioavailability, contributed to by its insolubility, instability, poor absorption, and rapid biotransformation. ZnO Np is a well-investigated biocompatible and apparently nontoxic nanomaterial that has shown promising anticancer and antimicrobial activity as well. In the article “Curcumin loaded zinc oxide nanoparticles for activity-enhanced antibacterial and anticancer applications”, different shapes of curcumin loaded ZnO Nps were investigated for their effectiveness and safety as an anticancer and antibacterial agent. The results indicate that curcumin loaded ZnO Nps are low toxic and a highly effective combination compared with their bare counterparts. Moreover, since nanoparticles show different absorption mechanisms through the gastrointestinal tract, it is a good alternative to mask compound which has low absorption capacity. In this study, other than the synergetic effect of curcumin loaded Nps, ZnO Nps act as a carrier system for curcumin, which has bioavailability issues.
Of particular note is the potential of this platform to act as an antibiotic-free formulation for use against infections caused by a range of different bacterial pathogens. Given the anticancer activity of the platform, it may prove to be of great use as an oncotherapy supplement, helping manage both the disease condition and opportunistic bacterial infections. The findings of this research open doors for different angles of curcumin and ZnO Np research. Therefore, the responsibility of the scientists is to use this finding to develop appropriate dosage foam for curcumin loaded ZnO Np.

Current increasing demands for the effective photocatalytic system for the treatment of industrial effluent with low cost and highly effective tools influenced the use of systems based on TMO (tri-metal oxide) that work in both acidic and basic pH systems, and that combat resistance to multiple drugs in bacterial infections and cancer. To solve the global environmental problems and save people from carcinogenic exposure, work has been done to establish highly effective, highly reliable and sensitive electrochemical methods involving the I–V approach for the detection of toxins present in environmental samples as well as in food/drinks or in their containers.
Dyes are extensively used in the textile industry, and considerable amounts are discharged into natural water reservoirs without any treatment. To treat wastewater, many catalysts have been investigated. However, it is tough to find an effective and efficient system for the waste- effluent treatment. The TMO system reported in the article “Photocatalysis, photoinduced enhanced antibacterial functions and development of a selective m-tolyl hydrazine sensor based on mixed Ag∙NiMn2O4 nanomaterials” was designed to meet the current need of industrial waste water treatment problem world-wide. For industrial effluent, especially from fabric and other industries where huge amounts of dyes are used, a proper treatment system is needed. This TMO system is very effective and highly efficient for the treatment of industrial waste water, it can degrade dyes present in waste water naturally in presence of sunlight. In particular, Ag·NiMn2O4 TMO can degrade dyes in both acidic and basic medium (in a wide pH range) in presence of sunlight. So, this TMO is useful for the treatment of varieties of industrial waste water. Further, its activity can be boosted by the use of a catalytic amount of H2O2 (as catalyst booster).
Ag·NiMn2O4 TMO is highly effective against both Gram positive and Gram negative MDR (multi drug resistant bacteria). This result is very promising because it is highly challenging to kill both Gram positive and Gram negative bacteria with a single drug (compound). It is expected that this compound can be a promising sterilizing agent for numerous industrial uses.
The authors also reports on a highly reliable and sensitive electrochemical method involving the I–V approach for the detection of hydrazine. Hydrazine is used as an industrial raw material to produce pesticides, herbicides, insecticides, corrosion inhibitors, pharmaceutical intermediates, dyestuffs, antioxidants, explosives, catalysts, fuel cells and rocket fuel, and it is a carcinogenic compound. In this study, the development of an electrochemical sensor using Ag·NiMn2O4 TMO nanomaterial on glassy carbon electrode (GCE) was developed. The m-tolyl hydrazine chemical sensor was fabricated with GCE coated with the Ag·NiMn2O4 TMO nanomaterial. The stability of the sensor probe was implemented by applying conductive Nafion (5% in ethanol) as a chemical glue under ambient conditions.
Finally, various real samples (collected from various environmental sources) were analyzed to check the applicability as well as the validity of the chemical sensor probe. As a potential sensor, it is reliable due to its good reproducibility, rapid response, high sensitivity, working stability for long duration and efficiency in the analysis of real environmental samples. Therefore, this method introduces a new route to develop selective chemical sensors using TMO nanomaterials for safety in the environmental and healthcare fields.
The authors strongly believe that the TMO research will have a tremendous effect on current as well as upcoming health and environmental global issues. Specifically, for a sustainable environment, medical and other health care issues.
