Ecological Modelling of Dietary Microplastic Exposure and Geographic-Patterns of Pancreatic Cancer Mortality in Italy
You are already at the latest version Pancreatic cancer (PC) mortality in Italy exhibits a persistent North–South macro-geographic gradient between 2003 and 2022, with significantly higher rates in northern regions. Whilst traditional risk factors partially explain this trend, the contribution of emerging dietary xenobiotics remains unexplored.
Microplastics in Vegan Foods from Spain, France, and Italy: Quantification and Characterization Across Dairy Alternatives, Meat Substitutes, and Sauces
The market rise of innovative vegan food products has been driven by global dietary trends moving toward plant-rich models. Nevertheless, new xenobiotics, such as microplastics (MPs), may be introduced via plastic packaging and multi-step industrial processing. Five commercial vegan items—seitan, quinoa burgers, soy desserts, vegan “Parmesan,” and vegan pesto sauce—that were gathered from Spanish, French, and Italian markets (N=15) were statistically assessed for MP contamination.
Hypothesizing the Systemic Resilience and Dynamic Recirculation of Nanoplastics: A Conceptual Biological Framework
You are already at the latest version The long-term biological fate of nanoparticles (NPs), which are increasingly identified in human blood and tissues, is still uncertain. Although toxicity remains the primary focus of current study, the human body also exhibits internal resilience mechanisms that alter the impact and transformation of NPs over time.
Hydrogen Donors as Selectivity Switches in Continuous-Flow Furfural Hydrogenation on Pd/C
You are already at the latest version The catalytic hydrogenation of furfural is a key reaction to valorize lignocellulosic biomass into value-added chemicals. In this work, the influence of different hydrogen donors on furfural hydrogenation under continuous-flow conditions was evaluated using a 10% Pd/C catalyst in a Phoenix Flow Reactor.
Pd/Ti 3 C 2 nanohybrids as heterogeneous catalyst for efficient catalytic reduction of hazardous water pollutants at ambient conditions
Abstract Nitrophenols are toxic priority pollutants that pose significant environmental and health risks, necessitating efficient strategies for their removal from wastewater. Catalytic transfer hydrogenation (CTH) using formic acid (FA) as a green hydrogen source represents a promising approach. This study reports the development of MXene (Ti3C2Tx)-supported palladium nanoparticle catalysts (Pd/Ti3C2Tx) for the efficient reduction of 4-nitrophenol (4-NP) under ambient conditions.
Liquid-phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel
Introduction Plastic pollution has become one of the most pressing environmental challenges. For instance, an estimated 4.8–12.7 million metric tons of plastic waste were dumped into the oceans in a single year.1 Over time, this debris fragments into microplastics – particles <5 mm – which are now detected across the globe, from oceans and soils to the air.

Biomass valorization using 3D-printed catalysts - Communications Chemistry
Abstract Catalytic biomass valorization into value-added chemicals is crucial to reduce reliance on fossil resources and mitigate environmental impacts. However, more than 90% of chemical manufacturing still relies on conventional catalysts, underscoring the need for sustainable alternatives. Three-dimensional (3D) printing offers unique opportunities to design catalysts with tailored geometries and pore architectures, enhancing mass transfer, active site accessibility, and reusability.

Hydrogen on the horizon: overcoming barriers to a sustainable energy transition
Green hydrogen has emerged as a potential cornerstone of global decarbonization, offering a lower emission energy vector that is capable of decarbonizing hard-to-abate sectors and strengthening energy security. Produced via electrolysis powered by renewable energy, its large-scale deployment remains constrained by technical, financial, and institutional barriers, particularly in emerging economies facing infrastructure deficits, fragmented policies, and unequal access to technology.

The Other Worldliness of Anka Moldovan
Trying to review Romanian-born artist Anka Moldovan’s latest exhibition "that which bursts" is, I have to admit, an excersize in arrogance, akin to claiming one can describe the joy felt by a sparrow in flight or the beauty of Handel's "Son nata a lagrimar". It is unwise to even attempt to reduce down to a few words the complexity of her worlds which, while still our world, feature exotic singularities like the event horizon of a black hole. "Slit-man.

Mentoring Doctoral Students in the Chemical Sciences
The relevance of effective mentoring of doctoral students in the chemical sciences is now widely recognized. However, the scholarly literature on the topic is virtually non-existent, and most approaches to faculty education on mentoring are based on “tips” and “guidelines. Following the analysis of current mentorship practices, we suggest a new approach based on evidence resulting from surveys of doctoral students, and on theory derived from studies in social and human sciences.

Reproducible Green Syntheses Using Hybrid Sol‐Gel Catalysts
1 Introduction Highlighting the technology, environmental and societal megatrends reshaping the chemical industry, a study in 2019 forecast that chemical productions would shift towards catalyzed processes under continuous flow, with oil-derved feedstocks increasingly replaced by feedstocks derived from biological resources.1 This shift would intrinsically lead to decentralized, smaller production plants in which chemicals are flexibly produced with little by-product (waste) formation and no...

The citrus economy in Sicily in the early bioeconomy era: a case study for bioeconomy practitioners
Introduction With a planting area exceeding 88 000 ha and 42 500 farms, Sicily hosts the largest citrus fruit (genus Citrus; family Rutaceae) cultivations in Italy.1 About 58 000 ha of land are cultivated with orange (Citrus sinensis), 21 000 ha with lemon (C. limon), and 5000 ha with mandarin (C. reticulata). The annual overall production of citrus fruits, which also includes clementines (C. clementina) and grapefruit (C.
Green chemistry and the bioeconomy: a necessary nexus
Introduction Chiefly based around the idea of pollution prevention, green chemistry emerged as a systematic research program around the early 1990s, following the publication, in 1996, of Green Chemistry: Designing Chemistry for the Environment,1 a book collecting the presentations given at a symposium held in 1994 during the 208th national meeting of the American Chemical Society. The symposium focused ‘on environmentally benign chemistry research in the international arena’.

Synthesis of [1,2,3]Triazolo[1,5‐a]quinoline‐3‐carboxamides Promoted by Organocatalyst and Base
Abstract We described here a simple and metal-free protocol to synthesize [1,2,3]triazolo[1,5-a]quinoline 3-carboxamides through a two-step synthetic strategy, in which the first step uses organocatalysis (10 mol% of diethylamine or 1,8-diazabicyclo[5.4.0]undec-7-ene, while the second step involves the use of inorganic base (1.2 or 0.1 equiv of potassium hydroxide). These reactions were performed between β-keto amides and o-carbonyl phenylazides in dimethylsulfoxide as solvent at 70 °C for 2 h.
