Kamala Das has always been vocal about the pain and suffering of the women in contemporary times. Her frankness in dealing with the taboo topics of the society invited unwanted controversies for her. The short stories of Kamala Das mostly speak about the uninhibited desires of the females who often face apprehensive behaviour for having their own ideas of sexuality. The paper is an attempt to read and justify the short stories “That Woman” and “The Little Kitten” in Padmavati the Harlot & Other Stories through a psychedelic approach. (Kamala Das selalu vokal tentang rasa sakit dan penderitaan para wanita di zaman kontemporer. Kejujurannya dalam menangani topik tabu masyarakat mengundang kontroversi yang tidak diinginkan baginya. Cerita pendek Kamala Das sebagian besar berbicara tentang keinginan perempuan yang tidak terhalang yang sering menghadapi perilaku khawatir karena memiliki gagasan seksualitas mereka sendiri. Surat kabar ini adalah upaya untuk membaca dan membenarkan cerita pendek "That Woman" dan "The Little Kitten" dalam Padmavati the Harlot & Other Stories melalui pendekatan psikedelik.)

AbstractSearching for the maximum coordination number (CN) in planar species with novel bonding patterns has fascinated chemists for many years. Using the experimentally observed cyclo[18]carbonD9hC18and theoretically predicted cyclo[14]carbonD7hC14as effective ligands and based on extensive first-principles theory calculations, we predict herein their perfect planar alkaline-metal-doped complexesD9hCs©C18+(1) andD7hNa©C14+(4) which, as the global minima of the systems with an alkaline metal atom located exactly at the center, possess the record coordination numbers of CN = 18 and 14 in planar species, respectively. More interestingly, detailed energy decomposition and adaptive natural density partitioning bonding analyses indicate that the hypercoordinate alkaline-metal centers in these σ + π dually aromatic complexes exhibit obvious transition metal behaviors, with effective in-plane (π-6s)σ, (π-7p)σ, and (π-5d)σ coordination bonds formed in Cs©C18+(1) and (π-3s)σ, (π-3p)σ, and (π-3d)σ coordination interactions fabricated in Na©C14+(4) to dominate the overall attractive interactions between the metal center and its cyclo[n]carbon ligand. Similar dually aromatic alkaline-metal-centered planarCsCs©C17B (2),C2vCs©C17-(3),C2vNa©C13B (5), andC2vNa©C13-(6) have also been obtained with CN = 18, 17, 14, and 13, respectively.

AbstractTransparent single crystals of Cs8[Si6O16] have been obtained by a high‐temperature reaction at 900 °C in an arc‐welded niobium crucible. The structure of Cs8[Si6O16] was solved and refined from single crystal X‐ray diffraction data: new structure type, P$\bar{1}$, Z = 2, a = 9.3544(3) Å, b = 11.1152(4) Å, c = 13.5035(5) Å, α = 101.311(3)°, β = 100.958(3)°, γ = 114.121(3)°, R1 = 0.032. The structure of Cs8[Si6O16] contains isolated dimeric cyclotrisilicate anions [Si6O16]8– that are separated by cesium atoms.The anion consists of six vertex‐sharing [SiO4] tetrahedra which form three interconnected rings: two rings consisting of three tetrahedra share edges with the opposite sides of a square of four [SiO4] thetrahedra. With respect to the plane of the four‐membered rings the triangles strike a trans‐type arrangement. [Si6O16]8– is the first example of the third possible structural arrangement in the class of unbranched dimeric cyclotrisilicate anions.

AbstractThe radioactivity of the Hanford site waste tanks is primarily from 137Cs and 90Sr, of which can both be selectively removed from solution using a crystalline silicotitanate (CST) ion exchanger. We are currently seeking waste forms alternative to borosilicate glass for Cs-CSTs. In order to obtain a fundamental basis for the development of an alternative waste form, we are investigating synthesis and characterization of CST component phases, namely Cs-Si-Ti-O phases. Two novel Cs-Ti-Si-O phases (one porous, one condensed) have been hydrothermally synthesized, characterized and evaluated as waste form candidates based on chemical and thermal stability, leachability, and ion exchange capabilities.

Collision of hyperthermal Cs+ ion beams with a Si(111) surface partially covered with water gives rise to emission of CsX+ cluster ions (X is a surface atom or molecule) even when the monomer X+ ions are not produced. The yield for atomic and cluster ion emission is examined as a function of Cs+ collision energy, based on which, we propose that CsX+ species are formed by recombination of the scattered, low kinetic energy Cs+ ions and the gaseous neutral species emanating from a surface. It is also demonstrated that under this condition the secondary neutral flux contains a large fraction of molecular units.
