He has also co-authored six books, published by John Wiley, Springer and MRF – USA and edited many others. He is Editor-in-chief/Editor of twelve international peer reviewed journals. having received multiple awards, he actively collaborates/visits as an invited researcher, visiting and chair professor in institutions in Japan, France, Saudi Arabia, Qatar, China, USA and India.
What areas does your laboratory work in? Dr. Manoj Gupta:My primary research focus is to develop lightweight materials that can assist in reducing greenhouse gas emissions. To that effect, we develop new monolithic materials, nanocomposites and syntactic composites. Further, we are also developing magnesium-based biomaterials targeted for temporary implant applications in human body.
Can you share your views on Bentham Science Publisher? Dr. Manoj Gupta:I am an academic staff member in NUS for more than 25 years. Except for me, my team members keep coming and going but a few of them have continued to work with me in this research area from different locations where they settled. Currently my samples are investigated in more than 10 labs all over the world.
What are the key findings from your most recent research? Dr. Manoj Gupta:The key findings are twofold. They can be summarized as follows:
Magnesium based materials are a greener option to replace aluminium based materials in automobile, sports, aerospace, defence, electronics and ground transportation sector. In some applications, they can even replace steels.
Magnesium based materials can be successfully used as temporary implants in the human body without the need for revision surgery. This reduces the risk of additional trauma for patients, and also saves the doctor’s time and medical costs.
What are the unique or intriguing implications of this discovery for research in the field? Dr. Manoj Gupta:Humans are currently facing the issues of global warming and toxicity in water bodies and land. The use of magnesium-based materials can greatly alleviate these issues putting less stress on our planet and future generations. It should be noted that magnesium is a nutritional element required for good health of humans, plants and animals. Adopting magnesium and magnesium technology can provide our future generation a healthier place to live in.
Can you share your views on Bentham Science Publishers? Dr. Manoj Gupta:Bentham Science Publishers are one of the leading publishers in the world actively engaged in publishing both subscription based and open access journals. Many of their journals are indexed well and referred to by researchers and scientists world over. They definitely provide an excellent platform to the world community of researchers to share their views.
Can you tell us something about Current Nanomaterials? Dr. Manoj Gupta:Current Nanomaterials is a rather new journal launched by Bentham Publishers. It addresses the fascinating aspects of nano-length scale So far it has published 77 articles and 8 thematic issues guest edited by researchers from six different countries. It is also a well indexed journal (For example, Google Scholar, Chemical Abstracts Service/SciFinder, J-Gate, CNKI Scholar, Ulrich's Periodicals Directory, and Journal TOCs) and hence can be accessed easily by researchers worldwide.
Have you published recently in any Bentham Journals? Dr. Manoj Gupta:Yes, I have recently published one article titled Using CaO Nanoparticles to Improve Mechanical and Ignition Response of Magnesium in the journal, Current Nanomaterials.
You are an expert on Magnesium and its use in materials. What makes Magnesium great for materials? Dr. Manoj Gupta:Magnesium is the lightest element that can be used in structural applications. It is almost 33% lighter than neurotoxic aluminium and one quarter as heavy as iron. It is one of the most abundant elements on planet earth and the universe and is thus sustainable. Therefore, its use in greenhouse gas critical applications is crucial in order to stem the temperature increase to under 20C of that in pre-industrial times. It is to be noted that the researchers have indicated that an increase in temperature beyond 20C will be a tipping point when the climate change may become irreversible.
Another important attribute of magnesium is its nutritional characteristics. This allows it to be used as a biomaterial. Currently magnesium-based stents and compression screws are already marketed and its potential use in mandibular reconstruction and as clips is being researched on.
Hence, Magnesium is one of the unique elements which can have a profound influence on engineering and biomedical sectors and multi-billion dollar industries are already opening up and will continue to develop this technology for the next 7-8 years.
You have collaborated with many universities. What are the challenges you have faced, if any, during such an experience? Dr. Manoj Gupta:As such, I have not faced any challenges. I keep the communication very clear with my collaborators and the respective roles each party has to play. Once we understand each other’s strength and the common goal, challenges remain at trivial levels.
What methods are useful for testing your findings and validating the results? Dr. Manoj Gupta:My main focus is to develop new materials using innovative/new processing methods that we keep on trying in the hope of improving science and technology. Reasonable success is realized in both these areas. To justify the use of new materials they must perform better than existing materials. The validating properties are a function of end applications. For example, if the materials are targeted as structural materials for automobile applications, we characterize by density, strength, fatigue and dynamic properties. If the materials are targeted to shield against electromagnetic radiation, we characterize by their electromagnetic shielding properties.
What do you look forward to in the near future? Dr. Manoj Gupta: really look forward to develop new materials and technologies that reduce the consumption of fossil fuels as that is the clear and present danger which human civilization is facing currently.
How do you go about sharing your research with both the scientific community and the general public? Dr. Manoj Gupta:I have published more than 525 research publications in peer reviewed international journals (which I feel is above average). I am a big supporter of the Open Access model as that allows the work to be accessible to the less privileged academic community. I take all the opportunities I get to give keynote and plenary talks and pitch them at a level so that they are also understood by non-experts. This helps to make sure my message is well received.
Any message for current and aspiring researchers interested in your specific research field? Dr. Manoj Gupta:I would like to encourage young scientists to think about developing science and technology that is not toxic to our planet and its inhabitants so that our future generations will have a wonderful place to live in.
