Temporal and spatial variability of surface ozone at Delhi and Antarctica
TL;DR: In this article, the temporal and spatial variability of 365 days; hourly mean surface ozone data for three different locations, New Delhi (a site of intense anthropogenic activity), Syowa and McMurdo stations in Antarctica (sites of clean background air).
Journal ArticleDOI
Light assisted irreversible resistive switching in ultra thin hafnium oxide
Hitesh Borkar,Hitesh Borkar,Atul Thakre,Sunil Singh Kushvaha,R. P. Aloysius,Ashok Kumar,Ashok Kumar +6 more
TL;DR: In this article, an ultra thin film (∼5 nm) high-k Hafnium oxide dielectric, grown on a doped p-Si(100) substrate by the atomic layer deposition technique has been investigated for resistive and capacitive switching with and without illumination of light.
Journal ArticleDOI
Strain-induced artificial multiferroicity in Pb(Zr0.53Ti0.47)O3/Pb(Fe0.66W0.33)O3 layered nanostructure at ambient temperature
TL;DR: In this article, layered nanostructures of the commercial ferroelectric Pb(Zr0.53Ti0.47)O3 (PZT) and the natural ferroic relaxor PbFe0.66W0.33 (PFW), were fabricated with a periodicity of PZT/PFW/PZTs and PZTs on MgO substrates by pulsed laser deposition.

TL;DR: It was observed that BA145 induced robust autophagy by targeting mTOR kinase (IC50 1 μM), leading to reduced expression of p-mTOR, p-p70S6K (T389), p-4EBP (T37/46) and p-S6 (S240/244) and Notably, inhibition of mTOR signalling by BA145 was followed by attendant activation of AKT and its membrane translocation.
