Transformacja energetyczna stanowi nie tylko wielkie wyzwanie czy jeden ze znaków rozpoznawczych trzeciej i zapewne kolejnych dekad XXI wieku, ale wiąże się także z procesem szerokich zmian prawnych, administracyjnych, organizacyjnych, a przede wszystkim społecznych. Zmieniające się standardy i nowe trendy rysują obszary nowych aktywności dla praktyków wielu branż, nowe zadania dla polityków, samorządowców i urzędników, jak również są inspiracją dla ludzi nauki. Transformacja energetyczna sukcesywnie generuje nowe wyzwania, jednych zadawala, innych zawodzi, a z pewnością stanowi szerokie i interdyscyplinarne pole badawcze dla przedstawicieli wielu dziedzin i dyscyplin naukowych: nauk inżynieryjno-technicznych (inżynierii chemicznej, inżynierii środowiska, górnictwa i energetyki), nauk ścisłych i przyrodniczych (nauk chemicznych, fizycznych, nauk o Ziemi i środowisku oraz biotechnologii), nauk rolniczych czy wreszcie nauk społecznych, w tym nauk prawnych, nauk ekonomicznych, nauk o polityce i administracji, nauk o bezpieczeństwie czy geografii społeczno-ekonomicznej i gospodarce przestrzennej.
Recovery of V2O5 from Spent Vanadium Catalysts: Materials Insights into Deactivation and Recycling Strategies
(2026-06-05) Drużyński, Sebastian; Wróbel-Kaszanek, Adriana; Igliński, Bartłomiej; Kiełkowska, Urszula; Mazurek, Krzysztof
The growing demand for vanadium and the environmental threat associated with spent catalyst masses have sparked widespread scientific interest in the recovery of V2O5 from deactivated vanadium-based catalysts, including those used in sulphuric(VI) acid production. This review places vanadium(V) recovery in the broader context of resource efficiency and the circular economy. The main deactivation mechanisms are analysed, including poisoning, sintering, and structural changes affecting catalytic activity and vanadium availability.
Hydrometallurgical approaches to vanadium recovery are discussed, with a particular focus on leaching agents, vanadium speciation in aqueous media, and subsequent separation techniques such as adsorption, solvent extraction, and vanadium(V) precipitation. Key process parameters influencing recovery efficiency, including temperature, pH, and caustic composition, are discussed to provide a comparative assessment of existing methods. The analysis highlights the advantages and limitations of current recovery methods and identifies gaps related to selectivity, process integration, and environmental impact. Overall, the study demonstrates that effective V2O5 recovery requires a thorough understanding of catalyst deactivation and solution chemistry. It also outlines models for developing more sustainable and economically viable recycling strategies.
Development of mixed-mode dispersive solid phase extraction of antisense oligonucleotides using commercial adsorbents
(Elsevier, 2026-06) Studzińska, Sylwia; Ostrowska, Karolina
Sample preparation remains a challenge in the bioanalysis of antisense oligonucleotides due to their polyanionic character, structural complexity, and interactions with proteins. In the current study, a novel mixed-mode extraction methodology for oligonucleotides was developed utilizing commercially available sorbents and subsequently applied to serum matrices. Notably, this work constitutes the first evidence that broadly available adsorbents, not specifically designed for oligonucleotide isolation, can nevertheless be effectively employed for their extraction. Five sorbents with various functional groups were systematically evaluated to elucidate their interaction with antisense oligonucleotides. As a result, dispersive solid phase extraction procedures were developed, with adsorption and desorption controlled by electrostatic, hydrogen-bonding, π-π, and hydrophobic interactions. Elution conditions were optimized using a central composite design, demonstrating that efficient desorption requires simultaneous modulation of salt pH and concentration, and organic solvent content. The results showed that extraction proceeds via a mixed mode mechanism. Two silica-based sorbents modified with phenylboronic acid and 2 (2 pyridyl)ethyl groups exhibited the most favorable balance of recovery, reproducibility, and sorption capacity, achieving recoveries up to 93%. Kinetic studies revealed rapid adsorption for both sorbents, while differences in desorption influenced method transferability from dispersive solid phase extraction to solid phase extraction. Finally, the extraction procedure for phenylboronic acid-based material enabled one step isolation of antisense oligonucleotides from serum without prior protein removal. Although substantial (1:5 v/v) serum dilution was required and recoveries were moderate (59-71%), the approach represents an alternative to currently used methods. Moreover, it expands the bioanalytical tools for mixed mode oligonucleotide extraction using widely available commercial sorbents.
The Pierogi Problem: Cosmopolitan Appetites and the Reinvention of Polish Food_book revies
(Slavonic and East European Review, 2026-04-01) Goszczyński Wojciech
What does Polishness taste like? Who defines its flavour? How is it connected to Poland’s history and the global consumer movement? These questions are explored by a team of scholars working at the intersection of Polish (Bachórz, Halawa) and international (Parasecoli) food studies.
Intercity coopetition and regional innovation: The role of urban polycentricity
(Sage, 2026) Yang, Yuting; Lu, Jiayi; Derudder, Ben
Intercity coopetition—the dynamic interplay between cooperation and competition—is central to regional innovation, enabling knowledge exchange across cities. However, the spatial organization of these dynamics among functionally diverse cities and their implications for regional innovation outcomes remain underexplored. This study examines how urban polycentricity, captured through the balance of intercity coopetition relations, affects regional innovation performance. Methodologically, we develop an intercity coopetition index that incorporates both geographical overlap in collaboration networks and technological proximity. Empirically, we draw on longitudinal patent co-application data from nineteen Chinese urban regions between 1990 and 2022. Using fixed effect and instrumental variables models, we find that a balance in cooperation alone has a negative effect on regional innovation. In contrast, regional innovation performance is driven by the interaction between the strength of competitive ties and the balance of competition across cities. We conclude by discussing the policy implications of these findings for fostering spatially coordinated innovation systems.
