Lanthanide(III) Metal-Organic Frameworks (Ln=Gd, Tb, Dy)Based on a C3 Symmetrical Tricarboxylate Linker McHugh, Darragh; Tong, Wenming; Bezrukov, Andrey; Farras, Pau; Zaworotko, Michael J.; Mayans Ayats, Júlia; Skelton, Jonathan M.; Barnett. Sarah; Pallipurath, Anuradha R.; Papatriantafyllopoulou, Constantina Lanthanide-based metal-organic frameworks have attracted significant interest due to their ability to combine porosity with one or more additional properties, providing an alternative method for the development of multifunctional materials. With this in mind, we report the synthesis and characterisation of the OnG5 family of MOFs with the formula [LnLH(DMF)3][(4-NH2Ph)3C](NO3)(CH3CO2H), where Ln=Gd (OnG5-Gd), Tb (OnG5-Tb), Dy (OnG5-Dy), and LH3−= the trianion of 4,4′,4′′-(1 E)-[4,4′,4′′-(methanetriyl)tris(benzene-4,1-diyl)tris(azan-1- yl-1-ylidene)]tris(methan-1-yl-1-ylidene)tribenzoic acid. OnG5 were synthesised in situ from the reaction of Ln(NO3)3.xH2O, pararosaniline base [(4-NH2Ph)3COH] and terephthalaldehydic acid in DMF. Their structure was studied through single crystal x-ray crystallography and confirmed with DFT calculations. OnG5 display a 2D, three-fold interpenetrated structure with a honeycomb lattice topology. They are the first examples bearing the ligand LHH3 and they display photoluminescence originating from an intraligand π-π* or n-π* transition. Dc and ac magnetic susceptibility studies conducted on the OnG5-Gd analogue revealed an absence of magnetic interaction between the metal centres.

Colloidal Cards: Effects of Game-Based Learning on Student’s Achievements in Colloidal Science Gómez, Elvira; Sousa Romero, Carmen; Serrà i Ramos, Albert Educational games garnered significant attention as effective learning tools, blending proven efficiency in improving learning outcomes with engaging and appealing environments that foster peer collaboration. Despite the central role of colloids in chemical applications, colloidal chemistry is often addressed superficially or qualitatively in many university settings, frequently relegated to noncompulsory subjects. Yet, the profound industrial and technological applications of colloidal chemistry, spanning fields like food, biomedicine, and paints, make it one of the most socially and economically impactful branches of chemistry globally. Hence, there is a pressing need to create effective tools that facilitate the teaching of colloidal systems, aiding in the comprehensive understanding of their characteristics and properties. This paper introduces a novel educational game named “Colloidal Cards” designed as an auxiliary tool for teaching and learning colloidal systems. The game aims to achieve three primary objectives: (i) facilitate the identification of everyday and industrial colloidal systems; (ii) impart knowledge on the key physicochemical properties of colloidal systems; and (iii) enhance comprehension of the stability of colloidal systems and the mechanisms to destabilize them.

The use of intraoperative venous shunts has been published by reference groups to allow successful resection. In our center we performed a total pancreatoduodenectomy for locally advanced pancreatic head adenocarcinoma with superior mesenteric vein occlusion (SMV) and splenomesentericportal confluent. The use of a transient ileo-caval shunt via a venous graft allowed resection of the tumor without repercussion on the bowel. The surgery ended with closure of the shunt, anastomosis of the graft to the portal vein and digestive reconstruction. The patient presented good tolerance to surgery and was discharged on the 7 th postoperative day. The pathology report described pancreatic adenocarcinoma ypT1N0(R0) regression grade GRT2/IIa, with 0/30 affected adenopathies.

Confinement-driven emergence of hyperuniform fluids Leoni, Fabio; Franzese, Giancarlo; Oguz, Erdal C.; Martelli, Fausto Controlling emergent structural order in spatially constrained systems is a fundamental challenge. Using large-scale simulations of a model fluid at equilibrium conditions, we show that geometric confinement alone can stabilize fluid and hyperuniform labyrinthine phases. Moreover, confinement can induce self-assembly into distinct regimes—ranging from nonhyperuniform to antihyperuniform configurations—providing a robust mechanism for tuning spatial order. Our results identify confinement as a minimal design principle for engineering systems with target structural properties, including (anti)hyperuniformity, without relying on genetic or chemical specificity, and with broad applications in multiple disciplines and technologies.
