Emerging technologies in solid drug delivery: An interview with Nadia Passerini
No full textNadia Passerini is interviewed by Hannah Makin, Commission Editor. Nadia Passerini is Associate Professor of Pharmaceutical Technology at the University of Bologna (Bologna, Italy). She obtained the degree in Pharmaceutical Chemistry and Technology at the University of Bologna in 1992 and the PhD in Pharmaceutical Science in 1997. Her research focuses on the study of drug delivery systems, developing new technologies and new apparatus for the production of solid dosage forms (microparticles, granules and tablets), which can optimize the bioavailability of drugs according to the specific needs of the therapy. Furthermore, she is interested in the solid-state characterization of the produced delivery systems in order to correlate their physicochemical properties to the in vitro release of the drugs. Currently, her research focuses in particular on the production and characterization of microparticles produced by the spray congealing technology. She is author of over 50 international peer-reviewed publications and over 50 contributions (poster and oral presentations) to national and international conferences

Sodium induced morphological changes of carbon coated TiO2 anatase nanoparticles High performance materials for na ion batteries
No full textThe most promising candidate as an everyday alternative to lithium ion batteries LIBs are sodium ion batteries NIBs . This is not only due to Na abundance, but also because the main principles and cell structure are very similar to LIBs. Due to these benefits, NIBs are expected to be used in applications related to large scale energy storage systems and other applications not requiring top performance in terms of volumetric capacity. One important issue that has hindered the large scale application of NIBs is the anode material. Graphite and silicon, which have been widely applied as anodes in NIBs, do not show great performance. Hard carbons look very promising in terms of their abundance and low cost, but they tend to suffer from instability, in particular over the long term. In this work we explore a carbon coated TiO2 nanoparticle system that looks very promising in terms of stability, abundance, low cost, and most importantly that safety of the cell, since it does not suffer from potential sodium plating during cycling. Maintaining a nano size and consistent morphology of the active material is a crucial parameter for maintaining a well functioning cell upon cycling. In this work we applied Anomalous Small Angle X Ray Scattering ASAXS for the first time at the Ti K edge of TiO2 anatase nanoparticles on different cycled composite electrodes in order to have a complete morphological overview of the modifications induced by sodiation and desodiation. This work also demonstrates for the first time that the nanosize of the TiO2 is maintained upon cycling, which is in agreement with the electrochemical stabilit
Memories Between Silence and Oblivion
No full textThe article is dedicated to a certain issue crucial for understanding the shaping of collective memory in the 20th century – the mechanisms creating areas of “collective oblivion” and the actions of restoring what has been removed from memory, repressed, omitted or kept secret. The studies and papers recalled in the erudite sketch go far beyond the borders of European memories, giving the readers an insight into the phenomena of memory and silence in their global dimension. By doing so, Luisa Passerini encourages her readers to abandon the arrogant belief in our uniqueness and cultural superiority.

MetalDetector v2.0: Predicting the geometry of metal binding sites from protein sequence
No full textMetalDetector identifies CYS and HIS involved in transition metal protein binding sites, starting from sequence alone. A major new feature of release 2.0 is the ability to predict which residues are jointly involved in the coordination of the same metal ion.

Introduction to the special Issue: Focus review - New and emerging battery technologies
No full textDriven by the ongoing global target of transitioning to a low-carbon economy, the demand for batteries is growing at an accelerating pace. Indeed, the development of batteries for transportation and stationary storage is one of the key strategies of the European Commission (EC) to enable the achievement of carbon neutrality by 2050.
This Special issue of Journal of Power Sources focuses on the current developments and future perspectives of various battery technologies, collecting 10 review articles from a wide range of European participants, i.e. 50 institutes from 12 countries, currently working together within Batteries Europe
Reductive Passerini/Tsuji-Trost Strategy towards beta,gamma-Unsaturated Amides
No full textInternational audienceThe Passerini reaction of α,β-unsaturated aldehydes with formic acid followed by a reductive Tsuji-Trost reaction affords β,γ-unsaturated amides. The overall process may be viewed as a one-carbon homologation of unsaturated aldehydes into amides
Disseminated cryptococcosis in a Patient With Metastatic Prostate Cancer Who Died in the Coronavirus Disease 2019 (COVID-19) Outbreak
No full textWe report the case of a 61-year-old patient with a history of prostate cancer affected by bone metastasis. He presented to our attention for ulcerous and necrotic cutaneous lesions unresponsive to antibiotics. The spread of cutaneous lesions and the onset of neurological symptoms suggested a cryptococcal disease, which was confirmed by lumbar puncture and cutaneous biopsy. We present the diagnostic and therapeutic approach to this case
