Growth of sillenite Bi12FeO20 single crystals: structural, thermal, optical, photocatalytic features and first principle calculations
Autor: Durga Sankar Vavilapalli, Ambrose A. Melvin, F. Bellarmine, Ramanjaneyulu Mannam, Srihari Velaga, Himanshu K. Poswal, Ambesh Dixit, M. S. Ramachandra Rao, Shubra Singh
Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-10 (2020)
Abstract Ideal sillenite type Bi12FeO20 (BFO) micron sized single crystals have been successfully grown via inexpensive hydrothermal method. The refined single crystal X-ray diffraction data reveals cubic Bi12FeO20 structure with single crystal param

Development of a high-rate-capable O3-structured ‘layered’ Na transition metal oxide by tuning the cation–oxygen bond covalency
Autor: Ishita Biswas, Bachu Sravan Kumar, Anagha Pradeep, Arpita Das, Velaga Srihari, Himanshu K. Poswal, Amartya Mukhopadhyay
Publikováno v: Chemical Communications. 59:4332-4335
By invoking fundamental principles associated with tuning of cation–oxygen covalency, a generic design criterion for the development of high rate-capable ‘layered’ Na-transition metal oxide cathode materials for Na-ion batteries has been laid o

Autor: Deepa Yadav, Neha Bura, Ankit Bhoriya, Jasveer Singh, Velaga Srihari, Himanshu K Poswal, Nita Dilawar Sharma
Publikováno v: Physica Scripta. 98:045707
The present manuscript reports high-pressure investigations on nano-crystalline Scandium Oxide (Sc2O3) through synchrotron angle dispersive x-ray diffraction technique (ADXRD) up to a pressure of ∼35.4 GPa using a diamond-anvil cell (DAC). The samp

Autor: Asheesh Kumar, Padmnabh Rai, Tapender Singh, Richa Goel, Himanshu K. Poswal, Vivek Shukla, Satish Kumar Dubey, Tapas Kumar Das, Vimarsh Awasthi, Amit P. Srivastava
Publikováno v: Plasmonics. 16:1339-1348
Surface-enhanced Raman spectroscopy (SERS) is a surface sensitive technique which gives enhanced Raman signal intensity of the molecules by roughening metal surfaces. It can be used to detect trace amounts of analysts including heavy metals, pesticid

Operando Investigations toward Changeover of Phase Assemblage and Associated Electrochemical Behavior during Lithiation/Delithiation Cycles of Sn-Based Intermetallic Electrodes
Autor: Manoj K. Jangid, Aastha Suman, Pranay Gandharapu, Amartya Mukhopadhyay, Srihari Velaga, Himanshu K. Poswal
Publikováno v: ACS Applied Energy Materials. 3:11249-11259
Moving toward the next-generation alkali metal-ion battery systems, poor cyclic stability of “alloying-reaction”-based anode materials, such as Sn, is still an unresolved issue of immense significa...
