A family of ionic supersalts with covalent-like directionality and unconventional multiferroicity

Y Gao, M Wu, P Jena - Nature Communications, 2021 - nature.com
Ionic crystals composed of elemental ions such as NaCl are non-polar due to directionless
ionic bonding interactions. Here, we show that these can develop polarity by changing their …

Superhalogens as building blocks of ionic liquids

AK Srivastava, A Kumar, N Misra - The Journal of Physical …, 2021 - ACS Publications
Ionic liquids (ILs) are composed of large asymmetric organic cations with a wide range of
anions. The simple anions, eg, halogen, result in less stable ILs, and therefore, ILs generally …

Superalkali-hydroxides as strong bases and superbases

AK Srivastava, N Misra - New Journal of Chemistry, 2015 - pubs.rsc.org
Alkali metals have the lowest ionization potentials of all the elements in the periodic table,
and their hydroxides are the strongest bases existing in the neutral form. So-called …

Single‐ and double‐electron reductions of CO2 by using superalkalis: An ab initio study

AK Srivastava - International Journal of Quantum Chemistry, 2018 - Wiley Online Library
CO2, a major contributor to global warming, can be balanced by converting it into fuels. The
reduction of CO2 has been difficult due to its extremely high stability. Recently, single …

OLi3O− anion: designing the strongest base to date using OLi3 superalkali

AK Srivastava, N Misra - Chemical Physics Letters, 2016 - Elsevier
Abstract LiO−(proton affinity= 1785 kJ/mol) is the strongest base reported in the literature,
followed by CH 3−(proton affinity= 1743 kJ/mol). Using ab initio and DFT calculations, we …

Nonlinear optical behavior of Li n F (n = 2–5) superalkali clusters

AK Srivastava, N Misra - Journal of molecular modeling, 2015 - Springer
Hyperlithiated clusters are known for their unusual bonding characteristics and lower
ionization potentials. This study reports nonlinear optical (NLO) properties of a series of …

Tuning the optoelectronic properties of superalkali doped phosphorene

A Hanif, R Kiran, RA Khera, A Ayoub, K Ayub… - Journal of Molecular …, 2021 - Elsevier
In this study, the nonlinear optical (NLO) properties of pristine phosphorene and superalkali
(Li 3 O) doped phosphorene are estimated through the density functional theory (DFT) …

Ab initio prediction of novel alkalides FLi2–M–Li2F (M= Li, Na and K)

AK Srivastava, N Misra - Chemical Physics Letters, 2015 - Elsevier
Alkalides are compounds possessing anionic alkali metals (Li−, Na−, K−, etc.). We have
predicted a new class of inorganic alkalides by sandwiching alkali atoms between Li 2 F …

Competition between alkalide characteristics and nonlinear optical properties in OLi3MLi3O (M = Li, Na, and K) complexes

AK Srivastava, N Misra - International Journal of Quantum …, 2017 - Wiley Online Library
Alkalides possess enhanced nonlinear optical (NLO) responses due to localization of
excess electrons on alkali metals. Employing MP2/6‐311+ G (d) level, we design novel …

M2X (M= Li, Na; X= F, Cl): the smallest superalkali clusters with significant NLO responses and electride characteristics

AK Srivastava, N Misra - Molecular Simulation, 2016 - Taylor & Francis
Abstract Hypervalent M2X (M= Li, Na; X= F, Cl) clusters are prototype species possessing
lower ionisation potentials than Li, therefore classified as superalkalis. This study reveals …
