    DESCRIPTION :

    Dr. Yatendra S. Chaudhary is a Chief Scientist at the CSIR-Institute of Minerals & Materials Technology (CSIR-IMMT), Bhubaneswar, and a Professor at the Academy of Scientific and Innovative Research (AcSIR), New Delhi. He earned a Ph.D. for research on nanostructured semiconductor synthesis for solar-driven water splitting at DEI, Agra, and for investigating SHI irradiation-induced modification of nanostructured semiconductors at IUAC, New Delhi. Subsequently, he moved to the Tata Institute of Fundamental Research (TIFR), Mumbai, India, where he carried out research in Materials Chemistry. While working at the University of Oxford, UK , as a Marie Curie Fellow, he designed enzyme-semiconductor-based photocatalysts for visible light-driven CO2 reduction and H2 production. His research accomplishments in nanomaterials and sustainable energy solutions have earned him prestigious accolades, including the Green Talent-2011 Award from the Federal Ministry of Education and Research (BMBF), Germany; CSIR Young Scientist Award-2013 in the Chemical Sciences section from the Council of Scientific & Industrial Research, India; and a prestigious Marie Curie Fellowship by the European Union. He holds numerous national and international patents, has published widely in high-impact peer-reviewed journals, and is the editor of the book "Solar Fuel Generation".

    EXPERIENCE : AREA OF INTEREST :
    For most of the advanced applications, there is a dominant requirement that nanocrystals in fact have organized assemblies with well-defined spatial separation, both in solution and solid state. Such self-assembly usually consists of intricate building units that are used to create well defined extended nano-structures with multi-dimensional ordering. The resulting self-organized structures give rise to inter-nanocrystal interactions ranging from dipole-dipole interactions to exchange interactions such as delocalization of carriers. Such interactions lead to the evolution of overall novel properties. My research work has therefore been focused on the development of facile synthetic (mainly wet chemical) approaches to fabricate semiconducting extended nanostructures (-highly desirable for advanced applications) with desired morphology and size for their subsequent key applications in energy conversion processes, that include- solar to chemical fuel conversion and white light emission materials/devices; and functional nanostructures for bio-medical, opto-electronic applications. The research activities being undertaken broadly are as follows:

    ARTIFICIAL PHOTOSYNTHESIS:

    The major focus is on designing the heterostructured photocatalysts with desired morphologies and size as to exploit the advantages associated with nanomaterials (such as quantum confinement effects, surface area), hetero-interface with appropriate energetics and layered structure of semiconductors for efficient solar H2 generation and CO2 and N2 reduction to fuels. Also underpinning the surface chemistry / electrochemistry / band gap engineering involved in photo-catalysis.

    INTRINSIC WHITE LIGHT EMITTING MATERIALS & DEVICES:

    The white LEDs available as of today, typically consists of a blue LED and one or more phosphors to convert part of the blue light to longer wavelengths and suffers from low spectral power distribution in the red region and dampening emission intensity. In addition, these are synthesized by sophisticated high vacuum methods, which are expensive methods.  We are working on developing the novel direct white materials that eliminate the phosphors use and can exhibit broad emission over the entire visible spectral range (400-800 nm) under ambient conditions and underpinning the photo-physics in these processes. We have recently discovered the formation of a stable complex under ambient conditions, extending the present understanding of molecular interactions, and exhibiting the unusually enhanced broad emission over the entire visible spectral range (Inorganic Chemistry, 2003; Chemistry - An Asian Journal, 2022, 10.1002/asia.202200948; Applied Materials Today, 2022, 27, 101407; US Patent No. 11104640 issued on 31st March, 2021; Patent filed in India, Ref No. 201811008726).

    BIOMATERIALS:

    The efforts are being made to fabricate biocompatible HAp based scaffolds which can exhibit improved corrosion resistant, mechanical strength. For this, the synthesis of a HAp-titania based scaffolds with different morphologies and the studies on their corrosion, cellular biocompatibility and adhesion behavior are undertaken. (Journal of Materials Chemistry, 2010, 20, 4949–4954).

    HOST-GUEST CHEMISTRY:

    Encapsulation studies of bio-/organic- molecules which are susceptible to their spatial confinement and their interactions with the surrounding species. Synthesis of stimuli responsive biodegradable nano-gels. Studies on their rheological behavior, surface charges etc. Evaluation of their potential for targeted drug delivery application and kinetics studies of drug uptake and release.
