Interesting publication on the different ways to crosslink HA, including crosslinkers other than BDDE. Various cross-linking techniques like chemical, physical, enzymatic, and hybrid methods impact the mechanical strength, swelling capacity, and degradation speed of the hydrogels. Assessment tools such as rheological analysis, electron microscopy, spectroscopy, swelling tests, and degradation studies are employed to examine their attributes.

“Single molecule fix pushes #zincbatteries to 99.96% #Coulombicefficiency and 600 cycles” “This makes them a promising solution for #largescaleenergystorage.” Sep 27, 2025 - Aman Tripathi “Researchers at Seoul National University have improved the performance and stability of #aqueouszincionbatteries by modifying a single molecule in the #electrolyte.” “The new electrolyte formulation enabled test cells to achieve an average #Coulombic efficiency of 99.96% and maintain stable operation for up to 600 charge-discharge cycles.” “The demand for #zincionbatteries lies in their use of abundant and low-cost materials, primarily #zinc and water, which also makes them safer than many #lithiumion systems.” ““Aqueous zinc-ion batteries (#AZIBs) offer compelling advantages owing to their inherent safety, cost-effectiveness, and the exceptional electrochemical properties of the #Zn metal anode.” “Engineering electrolyte’s #cosolvent” “However, their performance often fails at the interface between the #electrode and the #liquidelectrolyte. Water molecules in the electrolyte tend to decompose, and zinc deposits unevenly, forming #dendrites that can cause short circuits.” “To address this, the research team focused on engineering the electrolyte’s co-solvent.” “”A modified phosphate-based co-solvent, diethyl(difluoromethyl)phosphonate (#DEDFP), is developed by substituting an ethoxy moiety in #triethylphosphate (#TEP) with a difluoromethyl group,” explained the study.” ““This electrolyte demonstrates exceptional cycling stability by retaining 70.06% of its capacity over 486 cycles and sustaining operation beyond 700 cycles—far exceeding the stability of the TEP-based system, which fails after 381 cycles.”” “The structural modification creates a weaker, more optimal interaction with #zincions compared to the original TEP molecule. This reduces the energy required for the zinc ions to shed their surrounding solvent shell and deposit onto the electrode.” https://lnkd.in/exBZiDyr Source- original post Read all my posts #MariusPreston

New paper online at Nano Letters! We studied the hydrogen insertion into Pd nanostructure enriched with well-defined Σ3(111) grain boundaries (PdGB). In situ synchrotron XRD reveals that PdGB exhibits dramatically accelerated hydriding and dehydriding kinetics compared with Pd nanoparticles by over 1 order of magnitude! Strain mapping using environmental TEM shows that strain is highly localized at GBs and intensifies upon hydrogen exposure, indicating preferential hydrogen insertion along GB sites. DFT calculations provide mechanistic insight supporting these findings, showing that hydrogen insertion near Σ3(111) GBs is energetically more favorable and that tensile strain lowers insertion barriers. These results provide atomic-level insights into the role of GBs in hydride formation and suggest new design strategies for GB-engineered Pd-based functional materials. Great teamwork by Udeshika M.

New advances the triplet state (T1) reactivity that enables access to previously untapped chemical space with well defined 3D architectures Unlike yesteryears wherein the triplet state (T1) reactivity remained limited, typically requiring external photosensitizers to get to work, a new publication reports how structurally modified chiral iminium ions, integrated into extended π-systems, directly engages in T1 reactivity to overcome the intrinsic photophysical limitations of conventional iminium ion chemistry and enables to access previously inaccessible excited-state reaction manifolds following organocatalytic enantioselective [2 + 2] photocycloadditions And the best part, all this in the absence of any external photocatalyst! The generality of the process is demonstrated across a range of substrates bearing diverse functional groups, affording the desired products in consistently high yields and with excellent enantioselectivities and the fact that catalytic system can be extended to the intermolecular variant of the reaction, including complex alkene partners such as (R)-(–)-carvone https://lnkd.in/gj8XENaf Corti, V., Simionato, G., Rizzo, L. et al.

This study represents a major breakthrough in the field of asymmetric organic photocatalysis. For the first time, it demonstrates that chiral iminium ions, when embedded within extended π-conjugated systems, can directly engage in triplet-state (T₁) reactivity without the need for any external photosensitizer. This discovery contrasts sharply with previous approaches, where access to the triplet manifold typically required energy transfer from a separate photosensitizer, often a transition-metal complex. Here, the authors overcame the intrinsic photophysical limitations of classical iminium chemistry by designing intrinsically photoactive iminium ions capable of efficiently crossing from singlet to triplet states. This strategy unlocks a previously unexplored chemical space, enabling the formation of well-defined three-dimensional architectures through highly enantioselective [2 + 2] photocycloadditions. The process exhibits remarkable generality, tolerating a wide range of substrates and functional groups while delivering consistently high yields and excellent enantioselectivities. Notably, the catalytic system can also be extended to intermolecular variants, including challenging alkene partners such as (R)-(–)-carvone, highlighting the robustness and versatility of this approach. Altogether, this work paves the way for a new generation of purely organocatalytic, triplet-state photochemical transformations, broadening the synthetic potential of light-driven asymmetric catalysis beyond traditional metal-based systems.

📣Call for Reading: #Article Nickel Oxy-Hydroxy/Multi-Wall Carbon Nanotubes Film Coupled with a 3D-Printed Device as a Nonenzymatic Glucose Sensor by Murillo N. T. Silva, Raquel G. Rocha, Eduardo Mathias Richter, Rodrigo Alejandro Abarza Munoz, Edson Nossol https://lnkd.in/gz6hfmFF #NickelOxyHydroxy #CNTs #3Dprinting #nonenzymatic #glucose  #biosensors #mdpi #openaccess Abstract A rapid and simple method for the amperometric determination of glucose using a nanocomposite film of nickel oxyhydroxide and multi-walled carbon nanotube (MWCNTs) was evaluated. The NiHCF)/MWCNT electrode film was fabricated using the liquid–liquid interface method, and it was used as a precursor for the electrochemical synthesis of nickel oxy-hydroxy (Ni(OH)2/NiOOH/MWCNT). The interaction between nickel oxy-hydroxy and the MWCNTs provided a film that is stable over the electrode surface, with high surface area and excellent conductivity. The nanocomposite presented an excellent electrocatalytic activity for the oxidation of glucose in an alkaline medium. The sensitivity of the sensor was found to be 0.0561 μA μmol L−1, and a linear range from 0.1 to 150 μmol L−1 was obtained, with a good limit of detection (0.030 μmol L−1). The electrode exhibits a fast response (150 injections h−1) and a sensitive catalytic performance, which may be due to the high conductivity of MWCNT and the increased active surface area of the electrode. Additionally, a minimal difference in the slopes for ascending (0.0561 µA µmol L−1) and descending (0.0531 µA µmol L−1) was observed. Moreover, the sensor was applied to the detection of glucose in artificial plasma blood samples, achieving values of 89 to 98% of recovery.
