Journal ArticleDOI
Multifunctional Au-ZnO Plasmonic Nanostructures for Enhanced UV Photodetector and Room Temperature NO Sensing Devices
TL;DR: The sensing response of Au-ZnO nancomposite is enhanced both in UV and visible region, as compared to control ZnO, and the sensitivity is observed to be higher in the visible region due to the LSPR effect of Au NPs.
Journal ArticleDOI
Molecular Markers in Phylogenetic Studies-A Review
TL;DR: It appears that the use of molecular markers, though relatively recent in popularity and are not free entirely of flaws, can complement the traditional morphology based method for phylogenetic studies.
Journal ArticleDOI
Chemically reduced graphene oxide for ammonia detection at room temperature.
TL;DR: The synthesis of chemically reduced GO using NaBH4 and its performance for ammonia detection at room temperature and its use to manufacture a new generation of low-power portable ammonia sensors is reported.
Journal ArticleDOI
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
