Quality Control of the Anchoring of Steel Bridge Barriers by Non-Destructive Testing
(MDPI, 2020-01-07)Traffic barriers represent one of the basic road safety features. There are several types of traffic barriers based on the material from which they are made of and their location. Bridge structures are usually fitted with ... -
A quantitative analysis of 3D-cell distribution in regenerating muscle-skeletal system with synchrotron X-ray computed microtomography
(Springer Nature, 2018-09-20)One of the greatest enigmas of modern biology is how the geometry of muscular and skeletal structures are created and how their development is controlled during growth and regeneration. Scaling and shaping of vertebrate ... -
Quantitative Phase Dynamics of Cancer Cell Populations Affected by Blue Light
(MDPI, 2020-04-09)Increased exposition to blue light may induce many changes in cell behavior and significantly affect the critical characteristics of cells. Here we show that multimodal holographic microscopy (MHM) within advanced image ... -
Quantitative phase imaging through scattering media by means of coherence-controlled holographic microscope
(SPIE, 2015-11-01)A coherence-controlled holographic microscope (CCHM) enables quantitative phase imaging with coherent as well as incoherent illumination. The low spatially coherent light induces a coherence gating effect, which makes ... -
Quantitative phase imaging unravels new insight into dynamics of mesenchymal and amoeboid cancer cell invasion
(Springer Nature, 2018-08-13)Observation and analysis of cancer cell behaviour in 3D environment is essential for full understanding of the mechanisms of cancer cell invasion. However, label-free imaging of live cells in 3D conditions is optically ... -
Quantitative Raman Spectroscopy Analysis of Polyhydroxyalkanoates Produced by Cupriavidus necator H16
(MDPI, 2016-10-28)We report herein on the application of Raman spectroscopy to the rapid quantitative analysis of polyhydroxyalkanoates (PHAs), biodegradable polyesters accumulated by various bacteria. This theme was exemplified for ... -
The Quantitative-Phase Dynamics of Apoptosis and Lytic Cell Death
(Springer Nature, 2020-01-31)Cell viability and cytotoxicity assays are highly important for drug screening and cytotoxicity tests of antineoplastic or other therapeutic drugs. Even though biochemical-based tests are very helpful to obtain preliminary ... -
A Quantum Chemistry Approach Based on the Analogy with -System in Polymers for a Rapid Estimation of the Resonance Wavelength of Nanoparticle Systems
(MDPI, 2019-06-28)In this paper, the Variational Method based on the Hückel Theory is applied to NPs chain and aggregate systems in order to estimate the energy of the plasmon and, in turn, the resonance wavelength shift, which is caused ... -
Quantum Dots - Characterization, Preparation and Usage in Biological Systems
(MDPI, 2009-02-20)The use of fluorescent nanoparticles as probes for bioanalytical applications is a highly promising technique because fluorescence-based techniques are very sensitive. Quantum dots (QDs) seem to show the greatest promise ... -
Radiant wall cooling with pipes arranged in insulation panels attached to facades of existing buildings
(EDP Sciences, 2019-08-13)Radiant systems are being increasingly used for space heating and cooling of buildings. The contemporary research of radiant systems addresses mainly floor and ceiling structures. Research regarding the possibilities of ... -
Raman and XPS studies of ammonia sensitive polypyrrole nanorods and nanoparticles
(Springer Nature, 2019-06-11)Raman and XPS studies of ammonia sensitive polypyrrole nanorods and nanoparticles, respectively and tested upon ammonia exposure using Raman and X-ray photonelectrone spectroscopy (XPS). Characterization of both nanomaterilas ... -
Rapid Characterization of Biomolecules’ Thermal Stability in Segmented Flow-Through Optofluidic Microsystem
(Springer Nature, 2020-03-30)Optofluidic devices combining optics and microfluidics have recently attracted attention for biomolecular analysis due to their high detection sensitivity. Here, we show a silicon chip with tubular microchannels buried ... -
Rates of Reactions as a Mathematical Consequence of the Permanence of Atoms and the Role of Independent Reactions in the Description of Reaction Kinetics.
(Frontiers, 2018-09-01)Linear algebra treatment of the permanence of atoms (mass conservation) naturally leads to the transformation of formation or destruction rates of components of a reaction mixture into rates of reaction steps, which are ... -
Raw materials for mullite grog manufacturing
(IOP Publishing, 2018-07-07)The primary condition for manufacturing is the correct choice of raw material, a suitable treatment facility, and a kiln capable of firing at temperatures above 1400 °C. This paper assesses some local raw materials for ... -
Reactivity of meta-talc in sodium hydroxide medium
(IOP Publishing, 2018-07-12)This work deals with the reactivity of XRD amorphous delaminated and dehydroxylated talc phase (meta-talc), in alkali medium. Talc ore Luzenac H70 was treated in a stirred ball mill (attritor) for 30; 60 and 90 min with ... -
A Real Model of a Micro-Grid to Improve Network Stability
