P-Wave Positron-Hydrogen Scattering, Annihilation, and Positronium Formation
In a previous paper (Bhatia A.K. 2016), a hybrid theory for the scattering of positrons from hydrogen atoms was applied to calculate S-wave phase shifts, annihilation, and positronium formation cross sections.

CMB data constraint on self-annihilation of dark matter particles
Recently, self-annihilation of dark matter particles is proposed to explain the "WMAP Haze" and excess of energetic positrons and electrons in ATIC and PAMELA results.

Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

On the annihilation of dislocation dipoles in metals
During plastic deformation, there is a wealth of dislocation reactions, in which dislocation dipoles may play an important role. In this review, first, the history of dislocation dipole annihilation is revisited.

Spherical harmonics analysis of Fermi gamma-ray data and the Galactic dark matter halo
We argue that the decomposition of gamma-ray maps in spherical harmonics is a sensitive tool to study dark matter (DM) annihilation or decay in the main Galactic halo of the Milky Way.

Simplified models of dark matter with a long-lived co-annihilation partner [PDF]
We introduce a new set of simplified models to address the effects of 3-point interactions between the dark matter particle, its dark co-annihilation partner, and the Standard Model degree of freedom, which we take to be the tau lepton. The contributions

A scalable one‐step copolymerization strategy is developed to produce low‐cost microporous ion exchange membranes that boost both the efficiency and lifespan of flow batteries. When combined with organic electrolytes in aqueous systems, these membranes enable safe and cheap flow battery energy storage, supporting the widespread integration of renewable

The Unification Of The Intellect And The Intelligibe; Criticize And Analyze Haeri Yazdi's Viewpoint; Based on Jostarhaie Falsafi (Philosophical Queries) [PDF]
The ‘argument of correlation’ is one of arguments by which Mulla-Sadra attempts to prove the unification of the intellect and the intelligible. Haeri Yazdi in some of his philosophical books has tried to explain the argument.

Positron-Hydrogen Scattering, Annihilation, and Positronium Formation
In previous papers (Bhatia A.K. 2007, 2012) a hybrid theory for the scattering of electrons from a hydrogenic system was developed and applied to calculate scattering phase shifts, Feshbach resonances, and photoabsorption processes.
