Synthesis, surface and antimicrobial properties of novel sulfobetaines and the possibilities of their use in medical products
Surfactants, thanks to the structure of the molecule consisting of hydrophilic head and hydrophobic tail, show many interesting properties. The most important characteristics are their ability to reduce surface tension as well as wetting, solubilizing, emulsifying and antimicrobial properties. Sulfobetaine surfactants are one of the groups of surfactants which may show antimicrobial effects. As a result of their specific structure, they can exhibit many desirable features at the same time and are a research material of high potential.
The cooperation between the teams of the Poznań University of Economics and Business and the National Taiwan University in Taipei, established in 2013, resulted in the publication of an article in the Journal of Surfactants and Detergents (DOI: 10.1007/s11743-016-1838-3). The results of the joint research have been noticed and served as basis for further cooperation, which is why the teams have been recommended for funding research from the National Centre for Research and Development. The objectives of the project include:
– synthesis of sulfobetaine surfactants and their spectroscopic characteristics, as well as the characteristics of surface activity;
– evaluation of antimicrobial activity, as well as the therapeutic and toxic effects of the synthesised compounds.
The obtained results will allow for a broad characterization of surface and antimicrobial activity of sulfobetaine obtained and will indicate the potential use of these compounds as substances with therapeutic effect.

Semiotics of justice: organizing of translation process in the work of a lawyer – the case of Poznań district
Have you ever wondered how the work of a lawyer looks like? But really, what it would be to walk the shoes of attorney at law?
Let’s say, that you come to work at 10 a.m. because you were working late on this succession case. Your assistant Joan is already waiting for you with the coffee – you didn’t even have to ask. It’s nice by her side, isn’t it? Would you smile at her? You come to your office and sit at the oak desk. You hand the morning paper – The Voice of Great Poland – but you do not really have the time to read the news, because Mrs. Kwiatkowska (the one with the alimony) is coming soon. You need to look through the papers. Recently she brought you a pile of documents to make the evidence out of them, because “that pig surely cheats on her! You can see it in his eyes! He always has dark circles under them when he comes back from work”. You are not really surprised, but what to do? Exactly, what to do?
In terms of semiotics the word ‘justice’ does not carry any specific meaning until it is associated with a specific experience of unfair treatment. At the same time the language and complexity of legal procedures requires suport of someone able to translate the interest of a given person into the strange system of ideas and to organize the case in such a way that it reflects proper relations between people in the light of law. In this respect, a lawyer does not state what is just but interprets and creates some image of social order, the justice of which is deliberated during the trial. What is the image? How does it form? These are some of the questions I try to address in my work in an attempt to understand the structure of the judicial system, not only as an organizational system but also as space for experiences and relations between people.
The work of a lawyer seem to be governed by many rationalities, defining different solutions as equally right courses of action. We do not know what kind of logics compose the lawyer’s reality and we don’t know how they influence the way he or she enacts its role in the world of judiciary. Decoding these unknowns may tell us a lot about ourselves and organizing the ideas of justice, to which I dedicate this research project and all my efforts.
Stock liquidity on the capital market and its importance for corporate finance
What is liquidity? It has many meanings, but in reference to shares it means the ease with which these shares can be bought or sold. The studies conducted over the past 30 years indicated that the harder it is to sell (liquidate) given securities, the higher earnings are required by investors who want to buy it. Therefore, it can be stated that it has an impact on investors’ expectations on the capital market.
Export performance determinants of Polish firms in diverse institutional settings
Export is the basic way companies operate on international markets. Its development is fostered by globalisation, as the growing interconnectedness and integration of economies and societies around the world have intensified on an unprecedented scale in recent decades, particularly through technological advances related to transport, communication technologies and economic liberalization.
