Nanoengineering for enhanced toxic metals adsorption: Nanoengineering for Enhanced Toxic Metals Adsorption: From Synthesis to Biorecognition
Environmental contamination by toxic metals—such as Pb²⁺, Cr³⁺, and Hg²⁺—and organometallic species like monomethylmercury (MeHg) presents one of the most persistent global challenges due to their bioaccumulation, long-term toxicity, and resistance to degradation. This thesis addresses this critical issue through a multidisciplinary approach combining nanotechnology, environmental chemistry, biosensor engineering, and …
The integrated impact of artificial gravity and vibration exercise training on muscle structure and function
During space sojourns, astronauts experience musculoskeletal deconditioning caused by the lack of gravity. The adaptation of the musculoskeletal system to inactivity and unloading of the weight-bearing limbs may be countered by daily exercise. However, current exercise devices and strategies employed on the International Space Station (ISS) do not appear to …
Development of aerosolizator for disinfection of radiological devices and rooms using steriplant©n and assessment
Magnetic resonance imaging (MRI) is a diagnostic method that is used for broad range of hospitalized patient, emergency patients, chemotherapy treated and as well the patients that may have infectious diseases. Because the examinations of different patients are usually performed with the same equipment in the same environment, the surfaces …
Enhancing the performance of highly filled polymerbonded Nd-Fe-B magnets: Integrated advanced surface treatments and additive manufacturing
This doctoral dissertation present research aimed into enhancing polymer-bonded Nd–Fe–B magnets through innovative surface treatments and additive manufacturing techniques, focusing on improving their mechanical strength, magnetic characteristics, and environmental stability. This research is critical for broadening the applicability of these magnets in sectors like green technologies and motion control systems. …
Design-based optimization of a custom permanent magnet focused on a reduced raw-material consumption
Permanent magnets are vital parts of various devices, above all, those which are essential for the transition to a green society. However, they are made of materials, including rare-earth elements, for which unlimited availability cannot be taken for granted. Therefore, it is desirable to reduce the content of these materials …
Contact-free physiological monitoring of cardiorespiratory states using radar and optical sensors
Omnipresence of sensor-equipped devices spurred rapid development of e-health and mhealth applications in the past decades. Despite their wide-spread adoption in the form of wearables, such devices are ultimately not a universal or ideal solution for regular health monitoring due to their reliance on battery, requiring skin contact and general …
Low-Pressure Plasma Functionalisation of Fluoropolymers
In the present thesis, the problem of the functionalisation of fluoropolymers was addressed. As chemical methods for the functionalisation of fluoropolymers apply environmentally harmful chemicals, the research was directed to low-pressure non-equilibrium radiofrequency (RF) inductively coupled plasmas of environmentally friendly gasses. The research was focused on polytetrafluoroethylene (PTFE), the most …
Quantitative imaging of cisplatin in tumour samples by laser ablation inductively coupled plasma mass spectrometry
Medicine relies on imaging techniques such as ultrasound, magnetic resonance, computed tomography and histopathological image analysis because they provide valuable data needed for the diagnosis and treatment of diseases and injuries. Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is often used in research and for the advanced diagnosis and …
Mechanisms for colloidal stabilization of magnetic nanoplatelets
The dissertation presents a study of the colloidal stabilization of ferrimagnetic barium hexaferrite nanoplatelets in various isotropic and nematic media for the preparation of ferromagnetic fluids. Colloidal stability is the most important requirement to obtain a ferromagnetic liquid of barium hexaferrite nanoplatelets that exhibits spontaneous magnetization in the absence of …
High-precision wide-bandwidth isolated current measurement in networked devices
With the increasing use of electricity powered devices and processes in our daily lives, the need for the precise measurement of electrical currents across more than 15 decades from below nA to tens or hundreds of kA has become inevitable both for billing and more optimal energy distribution purposes as …
