Micro- and nanogels are widely used to stabilise emulsions and simultaneously implement their responsiveness to the external stimuli. One of the factors that improves the emulsion stability is the nanogel softness. Here, we study how the softest nanogels that can be synthesised with precipitation polymerisation of N-isopropylacrylamide (NIPAM), the ultra-low crosslinked (ULC) nanogels, stabilise oil-in-water emulsions. We show that ULC nanogels can efficiently stabilise emulsions already at low mass concentrations. These emulsions are resistant to droplet flocculation, stable against coalescence, and can be easily broken upon an increase in temperature. The resistance to flocculation of the ULC-stabilised emulsion droplets is similar to the one of emulsions stabilised by linear pNIPAM. In contrast, the stability against coalescence and the temperature-responsiveness closely resemble the one of emulsions stabilised by regularly crosslinked pNIPAM nanogels. The reason for this combination of properties is that ULC nanogels can be thought of as colloids in between flexible macromolecules and particles. As a polymer, ULC nanogels can efficiently stretch at the interface and cover it uniformly. As a regularly crosslinked nanogel particle, ULC nanogels protect emulsion droplets against coalescence by providing a steric barrier and rapidly respond to changes in external stimuli thus breaking the emulsion. This polymer-particle duality of ULC nanogels can be exploited to improve the properties of emulsions for various applications, for example in heterogeneous catalysis or in food science.

Exploring the inhibitory potential of the antiarrhythmic drug amiodarone against Clostridioides difficile toxins TcdA and TcdB

Centro de Investigación en Enfermedades Tropicales and Facultad de Microbiología, Universidad de Costa Rica
The intestinal pathogen Clostridioides difficile is the leading cause of antibiotic-associated diarrhea and pseudomembranous colitis in humans. The symptoms of C. difficile-associated diseases (CDADs) are directly associated with the pathogen’s toxins TcdA and TcdB, which enter host cells and inactivate Rho and/or Ras GTPases by glucosylation. Membrane cholesterol is crucial during the intoxication process of TcdA and TcdB, and likely involved during pore formation of both toxins in endosomal membranes, a key step after cellular uptake for the translocation of the glucosyltransferase domain of both toxins from endosomes into the host cell cytosol. The licensed drug amiodarone, a multichannel blocker commonly used in the treatment of cardiac dysrhythmias, is also capable of inhibiting endosomal acidification and, as shown recently, cholesterol biosynthesis. Thus, we were keen to investigate in vitro with cultured cells and human intestinal organoids, whether amiodarone preincubation protects from TcdA and/or TcdB intoxication. Amiodarone conferred protection against both toxins independently and in combination as well as against toxin variants from the clinically relevant, epidemic C. difficile strain NAP1/027. Further mechanistic studies suggested that amiodarone’s mode-of-inhibition involves also interference with the translocation pore of both toxins. Our study opens the possibility of repurposing the licensed drug amiodarone as a novel pan-variant antitoxin therapeutic in the context of CDADs.

This dataset covers additional analytical data and supplementary 3D printer files of a publication describing an NMR-based screening approach to monitor the formation of complexes. Changes within reaction mixtures containing metals and ligands were recorded on a small scale via a simple but reliable protocol. Based on the obtained data, we could draw conclusions on the formation of 2-(1', 2', 3'-triazol-1'yl)quinoxaline-based transition metal complexes. The NMR screening results obtained were confirmed by the repetition of selected experiments on a large scale (reported in the repository Chemotion) and wherever possible, the type of complex obtained was evaluated by crystal structure elucidation (reported in the CCDC). We could show the versatile complexation of the selected ligands with copper, gold, and silver in a bridging, chelating, or monodentate manner. The calculated theoretical properties supported the experimental results and enabled initial in silico predictions of similar compounds before conducting the complexation experiments and structural analyses.

The bulk modulus, K, quantifies the elastic response of an object to an isotropic compression. For soft compressible colloids, knowing K is essential to accurately predict the suspension response to crowding. Most colloids have complex architectures characterized by different softness, which, additionally, depends on compression. In this article, we determine the different values of K for the various morphological parts of individual nanogels and probe the changes of K with compression. Our method uses a partially-deuterated polymer, which exerts the required isotropic stress, and small-angle neutron scattering with contrast matching to determine the form factor of the particles without any scattering contribution from the polymer. We show a clear difference in softness, compressibility and evolution of $K$ between the shell of the nanogel, and the rest of the particle, depending on the amount of crosslinker used in their synthesis.

Photoswitchable unnatural amino acids (psUAAs) play a crucial role in the engineering of light-sensitivity in enzymes, which holds significant promise for diverse applications such as biotherapy and biocatalysis. Besides near-quantitative photoconversion, the success and expediency of a psUAA for a certain application is defined by its interaction potential with the enzyme, its thermal stability and its effective wavelength of irradiation. To establish high versatility in the current repertoire, we have designed and synthesized six psUAAs based on azobenzene, arylazopyrazole, arylazothiazole, hemithioindigo and spiropyran photoswitches. The resulting psUAAs exhibit an enhanced interaction potential within an enzyme owing to their capacity for hydrogen bonding, ionic interactions, and metal ion coordination. Moreover, we observed diverse photochemical behaviors among the psUAAs, with four of them reversibly switching between the isomers with purely visible light. Notably, we identified orthogonal aminoacyl-tRNA synthetases that facilitate the incorporation of five of the six psUAAs co-translationally and computationally analyzed the synthetase-psUAA interactions. Finally, we evaluated the photochemical behavior of the five psUAAs within an enzymatic model and tested the photocontrol of catalysis confirming their diversity. Ultimately, our findings significantly expanded the repertoire of psUAAs and demonstrated their feasibility for enzyme engineering studies.

The manuscript deals with the influence of different substituents of guanidine quinoline ligands on the electron transfer properties of the corresponding Cu(I) and Cu(II) complexes. The complexes were characterized with various methods but for further explanations of the substituents’ influences DFT calculations were essential. Correlations between the experimental and theoretical results revealed a deeper understanding of the properties of the copper complexes depending on the ligands’ substituents.
Density functional theory (DFT) calculations were performed with Gaussian 16 using the default UltraFine grid. The geometry optimizations were started from the geometry of the solid-state structures if available using the TPSSh functional and with the Ahlrichs type basis set def2-TZVP as implemented in Gaussian 16. As solvent model, the Polarizable Continuum Model (PCM) was used as implemented in Gaussian 16. As empirical dispersion correction, the D3 dispersion with Becke–Johnson damping was used as implemented in Gaussian 16.

Luminescent Ionic Heterobimetallic Diphosphine-β-diketiminate Complexes
In the present study, the response of ionic microgels to crowding is investigated. The microgels in the charged and uncharged state are probed in concentrated suspensions consisting of either neutral and charged microgels. We combined small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) with contrast variation to obtain information on both particle-to-particle arrangement and response of individual microgels in the same suspensions. The results clearly show that domination of faceting or deswelling is determined by the charge state of the microgel and its surroundings. The dataset includes the following measurements: SAXS and SANS in diluted and concentrated suspensions, form factor fits to the SANS and SAXS data, dynamic light scattering (DLS) data, viscosimetry data.

The structural characterization of microgels at interfaces is fundamental to understand both their 2D phase behavior and their role as stabilizers that enable emulsions to be broken on demand. However, this characterization is usually limited by available experimental techniques, which do not allow a direct investigation at interfaces. To overcome this difficulty, here we employ neutron reflectometry, which allows us to probe the structure and responsiveness of the microgels in-situ at the air-water interface. We investigate two types of microgels with different cross-link density, thus having different softness and deformability, both below and above their volume phase transition temperature, combining experiments with computer simulations of realistic in silico synthesized microgels. We find that temperature only affects the portion of microgels in water, while the strongest effect of the microgels softness is observed in their ability to protrude into the air. In particular, standard microgels have an apparent contact angle of few degrees, while ultra-low cross-linked microgels form a flat polymeric layer with zero contact angle. Altogether, this study provides an in-depth microscopic description of how different microgel architectures affect their arrangements at interfaces, and will be the foundation for a better understanding of their phase behavior and assembly.

The softness of an object can be quantified by one of the fundamental elastic moduli. The bulk modulus of the particle is most appropriate in the presence of isotropic compressions. Here, we use small-angle neutron scattering with contrast variation to directly access the bulk modulus of polymeric nanocapsules – pNIPAM-based hollow nanogels. We show that the size of the cavity is the most important quantity that determines the softness of hollow nanogels. During initial compression, the polymer collapses into the cavity and leads to a large change in the particle volume, resulting in a very small initial bulk modulus. Once the cavity is partially occupied by the polymer, the hollow nanogels become significantly stiffer since now the highly crosslinked network has to be compressed. Furthermore, we show that the larger the cavity, the softer the nanogel.

Data were systematically extracted from peer-reviewed literature, digitized when necessary, and harmonized to a standardized schema. All experimental records include comprehensive provenance tracking. Elemental compositions were normalized to dry or dry-ash-free basis. Missing values for key descriptors (e.g., HHV, lignocellulosic composition, elemental ratios) were imputed using Random Forest models or family-specific median values. Quality-control flags document closure checks for elemental and polymer balances. Derived descriptors include O/C and H/C molar ratios, Lignin Readiness Index (LRI), and energy/carbon recovery metrics.
This dataset provides a unified, curated collection of experimental results on the hydrothermal conversion of lignocellulosic and lignin-rich biomass, including hydrothermal treatment (HTT), hydrothermal liquefaction (HTL), and related process variants. The database covers diverse biomass feedstocks, reactor configurations, solvents, catalysts, temperatures, residence times, and operating conditions, with all records normalized to consistent units and yield bases.
