The correct detection and quantification of pollutants in water is key to regulating their
presence in the environment. Biosensors offer several advantages, such as minimal sample …

The necessity to control the feed water state in the second loop of a nuclear power plant
nuclear reactor is justified. The different methods of the state control of flowing water in the …

In this research, optical characterization of nickel ion solution and nanocrystalline cellulose-
graphene oxide (NCC-GO) thin film has been carried out using surface plasmon resonance …

All requirements for the express control of unstable hydrocarbon media and devices for their
implementation to obtain reliable measurement results are determined. The features of the …

We substantiate the necessity of developing a small-sized refractometer with Anderson's
differential cuvette for the highly accurate rapid check of the state of liquid media in real time …

A nonreciprocal biosensor for the detection of different liquid substances is proposed based
on an analog of the electromagnetically induced absorption (EIA-like) effect. Different bright …

We present a novel and low-cost optical sensor to obtain at the same time, fast and label-
free optical information such as reflectivity, refractive index and extinction coefficient of …

Long-range surface plasmon resonance (LRSPR), generated from a coupled plasmon
polariton in a thin metal slab sandwiched by two dielectrics, has attracted more and more …

We analyze the predictions of two recently developed effective-medium approximations for
the effective refractive index of a system of either transparent or plasmonic spherical …

This work focused on the application of the effective medium theory to describe the
extinction coefficient (Qext) in molybdenum trioxide (MoO3) doped with different kinds of …
