This paper demonstrates the application of smartphones as well as spectrophotometers as tools to demystify the mechanism leading to colour variation of 1,5-diphenylcarbazide functionalized gold nanoparticles (DPC-AuNPs) ...

The presence of radiation-induced defects and the high temperature of
implantation are breeding grounds for helium (He) to accumulate and form Heinduced
defects (bubbles, blisters, craters, and cavities) in silicon carbide ...
Multispecies bacterial attachment to carbon steel surfaces is not fully understood; for example, as to why the attachment of certain bacteria influences corrosion. In this study, finished steel, A 106 GB was exposed to a ...
Phycobilisomes (PBs) play an important role in cyanobacterial photosynthesis. They capture light and transfer excitation energy to the photosynthetic reaction centres. PBs are also central to some photoprotective and ...

We present deep ALMA Band 3 observations of the HCN, HCO+, and HNC(4–3) emission in SDP.81, a well-studied z = 3:042;
strongly lensed galaxy. These lines trace the high-density gas, which remains almost entirely unexplored ...
A significant public concern is how technologies that emit electromagnetic waves interact and affect the biota because they are linked to the dysregulation of genes involved in neurotransmission, oxidative stress, and ...
While IN738 Ni-based superalloy is a high strength alloy, it is feasible to improve its
properties at the bulk level by reinforcing with graphene nanoplatelets (GNPs), taking
advantage of the superior mechanical, ...
We introduce and study a class of quadratic Wasserstein distances on spaces consisting of generalized dynamical systems on a von Neumann algebra. We emphasize how symmetry of such a Wasserstein distance arises, but also ...
Demands for cheaper solar cells have led researchers to less complex, low-temperature,
vacuum-free thin-film deposition processes, like spray pyrolysis and sol–
gel spin coating. Previous studies of β-Ga2O3 thin-film ...
In the present study, the Schottky diode devices based on Ce and Sm co-doped
ZnO thin films were fabricated using the sol–gel spin-coating technique with Pd
and Pt as Schottky contacts. The structural and electrical ...

Flow boiling performance is affected by several factors, such as channel
characteristics and working fluid types. It is found that there is still limited study that discusses
the use of binary mixtures combined with high ...
