Novel Colloidal MoS2 Quantum Dot Heterojunctions on Silicon Platforms for Multifunctional Optoelectronic Devices.

TL;DR: Fabricated n-MoS2/p-Si 0D/3D heterojunctions exhibiting excellent rectification behavior have been studied for light emission in the forward bias and photodetection in the reverse bias and are found to be superior to the reported results on large areaPhotodetector devices fabricated using two dimensional materials.
Journal ArticleDOI

Coronavirus disease 2019 (COVID-19) outbreak: some serious consequences with urban and rural water cycle

TL;DR: The COVID-19 outbreak due to SARS-CoV-2 has raised several concerns for its high transmission rate and unavailability of any treatment to date Although major routes of its transmission involve respiratory droplets and direct contact, the infection through faecal matter is also possible.
Journal ArticleDOI

Tunable Direct Bandgap Optical Transitions in MoS2 Nanocrystals for Photonic Devices

TL;DR: In this paper, the size of nanocrystals could be varied within the diameter range of ∼4 to 70 nm, and a strong and tunable photoluminescence (560-518 nm) emission due to the quantum size effect of tiny NCs below a critical dimension was reported.
Journal ArticleDOI

Study of hydrophilicity and stability of chemically modified PDMS surface using piranha and KOH solution

TL;DR: In this paper, a simple and cost effective approach for surface modification of PDMS films involving wet chemical treatment in two-step processes: primarily involving piranha solution followed by KOH dip to improve hydrophilicity and stability of the PDMS surface.
Journal ArticleDOI

Design of Phase-Differentiated Reconfigurable Array Antennas With Minimum Dynamic Range Ratio

TL;DR: In this article, a real-coded GA was proposed for the optimal design of a dual-beam linear array antenna with phase only control, where the problem is to find a common amplitude distribution with minimum dynamic range ratio (DRR) that will generate a pencil beam with zero phases and a flat-top beam with continuously controllable phases of an analog phase shifter.
