Pressure-Dependent Tuning of Photoluminescence and Size Distribution of Carbon Nanodots for Theranostic Anticancer Applications

2020

Carbon nanodots (CDs) have recently attracted attention in the field of nanomedicine because of the biocompatibility, cost-effective nature, high specific surface, good near infrared (NIR) photothermal conversion into heat and tunable fluorescence properties, which have paved the way toward incorporating use of CDs into innovative anticancer theranostic platforms. However, a reliable synthesis of CDs with established and controlled physiochemical proprieties is precluded owing to the lack of full manipulation of thermodynamic parameters during the synthesis, thus limiting their use in real world medical applications. Herein, we developed a robust solvothermal protocol which allow fine contr…

Electronic Energy Meter Based on a Tunnel Magnetoresistive Effect (TMR) Current Sensor

2017

In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.

Prompt Determination of the Mechanical Properties of Industrial Polypropylene Sandwich Pipes

2021

A simple and prompt method to determine the mechanical properties of industrial multilayer extrusion polypropylene pipes for a gravity sewer network is suggested. The engineering formulas included for calculating the permissible thickness and relative position of a foam core in the pipes are based on a linear-elastic approximation and the rule of mixtures. The applicability of the approximation was justified experimentally during investigation of the effective tensile characteristics of single- and multilayer pipes and each layer specimen by using traditional tests and finite-element calculations. The results obtained were used to formulate engineering recommendations for calculations of th…

Electrical conductivity of glass fiber-reinforced plastic with nanomodified matrix for damage diagnostic

2021

The electrical conductivity of glass fiber-reinforced plastic (GFRP) with epoxy matrix modified by multiwall carbon nanotubes (MWCNT) was studied. The electrical conductivity of nanomodified lamina and multi-layered GFRP was investigated on several levels using a structural approach. Components of the electrical conductivity tensor for unidirectional-reinforced monolayer were calculated similarly as in micromechanics using the conductivity of the nanomodified matrix. The electrical conductivity of multilayer composite was calculated using laminate theory and compared with values measured experimentally for various fiber orientation angles. Calculated and experimental data were in good agree…

Border and Regional Studies Network

Network, established in 2021, under the CEEPUS program. The University of Opole is a leader of the network of 15/universities from Poland, Czech Republic, Slovakia, Hungary, Romania, Moldova, Macedonia, Bulgaria, Slovenia, Montenegro. We propose unique Border and Regional Studies Network comprised of 15/universities located in 10/countries of Central Europe and Balkans. The network’s thematic framework will address one of the crucial problems and challenges of the XXI century like migrations, multi-ethnic societies, revitalization of regional identities, border crossing and border revitalization (the last one strongly influenced by the pandemic). The main objective of the network is sharing…

Europe between Mobility and Security: the challenges of illicit trades in the Mediterranean Area

Europe between Mobility and Security: the challenges of illicit trades in the Mediterranean Area

Human Sciences Center

Created in the 1950s to break down the barriers between disciplines and university traditions in the Humanities and Social Sciences (SHS), the Maisons des Sciences de l'Homme (Human Sciences Centres) have expanded to cover the entire country and to meet the challenges of research in SHS at the beginning of this century. The MSH is a collective dynamic that starts from the research teams, organizes the confrontation with the actors through whom social transformations take place, proceeds by setting up problems that are themselves objects of interdisciplinary programs, leading to research results that are brought to circulate on the scenes of social debate. MSH is a joint venture of almost al…

Master Degree in Migration Studies: Governance, Policies, and Cultures

MIGRANTS project intends to reinforce the institution capacity of Tunisia Higher Education System. Given its geo-political situation, Tunisia can play, in the specific context of Migrations, an important role for itself and for the surrounding countries, including, of course, the EU member states. In a coherent sense with Global Compact MIGRANTS project promotes a broad multi-stakeholder partnership to address higher education in Migration Studies in Tunisia in all its dimensions by including migrants, diasporas, local communities, civil society, academia, the private sector, parliamentarians, trade unions, national human rights institutions, the media and other relevant stakeholders in mig…

The UL Centre for European and Transition Studies

The UL Centre for European and Transition Studies (CETS) was established in 2000 as a unit of the University of Latvia. It aims to promote and support interdisciplinary academic and applied research on European issues, involving students from both EU Member States and from a number of third countries. CETS focuses on sectors, such as economics, political science, law, public administration and regional policy. CETS includes projects by Jean Monnet and Marie Curie from European Commission and provides advice to state institutions on economic and social development issues related to European integration. CETS operates as an internationally recognised forum for debate for academics, graduates …

Interdisciplinary Public Policy Mainz

Public institutions can only use their various policy instruments productively if they are able to adequately assess the effect they have on human behavior. Thus, the design of effective institutions and policies requires not only an understanding of the relevant and often interdependent social, economic, political, and legal contexts and mechanisms but it also requires a deep knowledge about how human beings make decisions. In order to obtain the necessary insights, the Interdisciplinary Public Policy (IPP) Research Unit constituted at JGU in 2014 incorporates a number of different disciplines: economics, business administration, computer science, political science, sociology, communicatio…
