It is with great pride that we announce that the article "Verhulst-type equation and the universal pattern for global population growth" by Agata Angelika Sojecka and Aleksandra Drozd-Rzoska published in PLoS One  has received recognition and was highlighted on the Polish Academy of Science  Portal - LINK

 Our Article Highlighted !

We are pleased to announce that in recognition of the large number of 'downloads' and a significant number of citations of our team's publications that appeared in the Nanomaterials magazine, we have received as many as 5 special invitations to publish in this journal 'free of charge':

 

2 publications in Nanomaterials Special Issue "The impact of nanoparticles on phase transitions in liquid crystals' - editors

                                                                           Prof. Sylwester J. Rzoska and Prof. Aleksandra Drozd-Rzoska,

1 'invited' review report in Nanomaterials  "Impact of nanoparticles and pressure on soft matter systems." (Aleksandra Drozd-Rzoska)

2 'invited' publications in Nanomaterials concern the simultaneous impact of high pressures and nanoparticles on materials relevant

                                                                 to new generations of batteries. (will be published soon)

 

   It is worth emphasizing that Nanomaterials (MDPI) is a broadly valued Open Access journal with a high Impact Factor IF=5.3

 NEW  Insight into  HPP  Food !

Our co-authored paper, named the ‘Progressive Review’ has recently been published in an international, peer-reviewed Journal Foods (publisher: MDPI, Basel; included in ISI Master ‘Philadelphia’ Journal List): impact factor IF(2023)=5.2, and100 points of MNiSW (Poland). It is notable, that the Social Institute for Care Excellence(SCIE) awarded the Foods Journal by the highest category Q1.

 

The 38-page publication entitled: ”Food Preservation in the Industrial Revolution Epoch: Innovative High Pressure Processing (HPP, HPT) for the 21st-Century Sustainable Society ." [A. A. Sojecka, A. Drozd-Rzoska, S. J. Rzoska, Foods 13(2024) 3028]

This paper is part of a dedicated volume: ‘Future of Food: Innovation & amp; Sustainability’ [Foods 13 (2024)].

 

The paper discusses the significance of innovative methods of food preservation, with particular emphasis on high pressure processing (HPP), in the context of socio-economic and technological issues that are the driving force of the Industrial Revolution epoch.

We are currently in the 5th Industrial Revolution time, for which Sustainable an, during which sustainable and pro-health development Pro-Health Development is one of the main goals. The paper discusses new business opportunities emerging for innovative implementations of HPPP  (related to & quot; cold & quot; pasteurization) and HPT (related to pressure sterilization) methods of food,

including the creation of qualitatively new products.

The general distribution scheme of HPP and HPT-treated dishes focused on specific pro-health requirements. The elements of the system presented in Figure  could be used in some branches of the catering business, for example, in popular eateries selling meals ‘by weight’.

This WEBSITE was created to realize the following, main  GOALS:

Soft Matter systems have common features, such as the dominance of elements or local structures on the mesoscale, combined with their relatively weak interactions, which turns out to be sufficient to obtain a tendency to self-organize with even a small change in parameters. This additionally leads to extraordinary sensitivity to even minor endogenous and exogenous factors, e.g., nanoparticles and pressure. In the case of the latter, relatively low pressures P~1 GPa, or even much lower ones, can lead to phases/states with exotic features, often persisting after decompression.

Worth stressing, that for "classical hard matter" systems, a pressure similar to that at the Earth's core (~300 GPa) is typically required, and the resulting "exotic" properties most often disappear upon decompression.
