Ernst Shaigardanovich Khaziakhmetov: scientist-researcher, teacher, person. 1936–2007 yy. [PDF]

open access: yesОмский научный вестник: Серия "Общество. История. Современность", 2022
The interest in the formation and development of historical science in the region led to the need to create a socio-political history of the Siberian region. This goal is achieved in the second half of the 20th century thanks to the efforts of a number

Liquid Viscosity Sensor Using a Surface Acoustic Wave Device for Medical Applications Including Blood and Plasma

open access: yesSensors, 2023
Blood viscosity is the defining health indicator for hyperviscosity syndrome patients. This paper introduces an alternative approach for the real-time monitoring of blood viscosity by employing a surface-horizontal surface acoustic wave (SH-SAW) device ...

Analysis of Red Blood Cell Samples using a Handheld Shear-horizontal Surface Acoustic Wave Biosensor [PDF]

open access: yes, 2023
Human red blood cells (RBCs) are highly studied by researchers and clinicians alike because RBCs play an essential role in medical diagnostics. RBCs are the most abundant component of whole blood. The accurate analysis of blood samples for blood cells is

Combined electronic nose and tongue for a flavour sensing system [PDF]

open access: yes, 2011
We present a novel, smart sensing system developed for the flavour analysis of liquids. The system comprises both a so-called "electronic tongue" based on shear horizontal surface acoustic wave (SH-SAW) sensors analysing the liquid phase and a so-called "

Investigation of Polymer–Plasticizer Blends as SH-SAW Sensor Coatings for Detection of Benzene in Water with High Sensitivity and Long-Term Stability [PDF]

open access: yes, 2016
We report the first-ever direct detection of benzene in water at concentrations below 100 ppb (parts per billion) using acoustic wave (specifically, shear-horizontal surface acoustic wave, SH-SAW) sensors with plasticized polymer coatings.

Removal of Non-Specifically Bound Proteins Using Rayleigh Waves Generated on ST-Quartz Substrates

open access: yesSensors, 2022
Label-free biosensors are plagued by the issue of non-specific protein binding which negatively affects sensing parameters such as sensitivity, selectivity, and limit-of-detection.
