Catalysis plays a major role in various chemical processes including petroleum, pharmaceutical, fine chemistry, and energy. The development of highly functional catalysts is therefore essential. To meet the growing demand for advanced materials, we have developed ceramic catalyst supports known for their chemical inertness and thermal resistance. Using light‐assisted 3D printing, we designed complex architectures for ceramic substrates tailored to specific technical requirements. We developed ordered porous silicon oxycarbide (SiOC) ceramic monoliths with an architecture suitable for use as catalyst supports. The active sites are introduced by functionalizing the ceramic surface with palladium (Pd) nanoparticles using Atomic Layer Deposition (ALD). This technique is advantageous for achieving highly dispersed nanoparticles with uniform size distribution and minimal aggregation. We evaluated the catalytic performance by studying the effect of Pd loading on a Suzuki–Miyaura coupling reaction in water, as well as the reusability of the 3D‐printed catalytic monolith. The system demonstrates up to 82% yield and exhibits excellent stability, with no leaching of the active phase observed during the reaction cycles. These results underline the potential of 3D‐printed SiOC monoliths to create highly efficient and reusable catalytic systems, paving the way for advanced applications in a variety of industrial sectors.

AbstractInorganic minerals that form via regulated biological processes exhibit remarkable properties. This is due to the involvement of macromolecules that control biomineralization. Even though the interactions of these biopolymers with solid mineral phases are intensely studied, not much is known about their involvement in the preceding steps of intracellular transport of the mineral building blocks. In this work, the model system of coccolith calcite crystallization is utilized to address the role of mineral‐associated polysaccharides in the transport of calcium ions. State‐of‐the‐art cryo‐electron tomography is used to image in situ ion‐rich dense phases in the wild‐type and in two mutant strains, defected in coccolith production. The results show that the abundance and solubility of the calcium‐rich condensates need to be finely tuned for proper crystallization. When the native macromolecular assemblage is compromised, calcium is still present in the calcifying fluid as a solute, but this is not sufficient for coccolith development. These results suggest that biomineralizing systems achieve superior regulation of crystallization due to the use of dense macromolecule‐rich phases.

Abstract2D metal–organic frameworks (2D‐MOFs) are an important class of functional porous materials. However, the low porosity and surface area of 2D‐MOFs have greatly limited their functionalities and applications. Herein, the rational synthesis of a class of mos‐MOFs with molybdenum disulfide (mos) net based on the assembly of trinuclear metal clusters and 3‐connected tripodal organic ligands is reported. The non‐crystallographic (3,6)‐connected mos net, different from the 3‐connected hcb net of graphene, offers abundant intralayer voids courtesy of the split of one node into two. Indeed, mos‐MOFs exhibit high apparent Brunauer‐Emmett‐Teller surface areas, significantly superior to those of other 2D‐MOF analogs. Markedly, hydrolytically stable Cr‐mos‐MOF‐1 displays an impressive water vapor uptake of 0.75 g g−1 at 298 K and P/P0 = 0.9, among the highest in 2D‐MOFs. The combined water adsorption and X‐ray diffraction study reveal the water adsorption mechanisms, suggesting the importance of intralayer porosities of mos‐MOFs for high‐performance water capture. This study paves the way for a reliable approach to synthesizing 2D‐MOFs with high porosity and surface areas for diverse applications.

AbstractThe surface curvature of catalysts has a decisive impact on their catalytic performance. However, the influence of a negative‐Gaussian‐curvature surface on the catalytic performance of porous catalysts has remained unexplored due to the lack of suitable samples. Bicontinuous‐structured porous structures can serve as ideal models, but they are known as “Plumber's nightmare” due to their highly difficult preparation. Here, using metal–organic frameworks as the precursor and polymer cubosomes as the template, a bicontinuous mesoporous Fe single‐atom catalyst (named bmFeSAC) with a Schwarz P surface is synthesized. The bmFeSAC catalyst has a large specific surface area of 916 m2 g−1 and uniformly distributed Fe‐N4 active sites with a 1.80 wt.% Fe content. The continuous channels enabled high utilization efficiency of the Fe‐N4 catalytic sites, while the negative‐Gaussian‐curvature surface enabled low reaction energy barrier. As an electrocatalyst of the oxygen reduction reaction, bmFeSAC delivered a high half‐wave potential of 0.931 V versus. RHE in alkaline electrolyte, reaching the leading level among those of the reported state‐of‐the‐art electrocatalysts. Furthermore, the bmFeSAC‐based Zn‐air batteries exhibited excellent performance, demonstrating the potential application of bmFeSAC. This study revealed that a bicontinuous‐structured porous structure can improve catalytic activity by increasing the utilization ratio of catalytic sites and, more importantly, by regulating the electronic structure of catalyst surfaces through the negative‐Gaussian‐curvature.

AbstractThe development of low‐cost and earth‐abundant phosphors for substituting expensive noble metals and toxic lead materials is currently of major importance for sustainable solid‐state lighting technologies. Hybrid copper halide materials are currently receiving considerable attention due to their unique and diverse structural and photophysical properties combined to their low cost and toxicity. This article reports the rational design of copper iodide compounds for developing single‐component white light emitters. By a ligand engineering strategy, the energy layout of the molecular clusters can be adjusted and the variation in the relative intensity of two emission bands can be obtained, enabling white light to be emitted. Temperature dependence of this dual‐emission feature also allows high contrast luminescence thermochromism. Thanks to their good solubility properties, the studied copper iodide clusters have been successfully incorporated within organic polymer leading to polymer materials with processability suitable for application development. Therefore, the potential applicability of these composite materials has been demonstrated in various fields as luminescence ratiometric thermometry, single‐component emitters for phosphor‐converted white‐light emitting diodes, and as ink for anticounterfeiting properties. This study highlights the power of the ligand design strategy to develop high potential multifunctional materials based on light‐emitting copper materials.

AbstractRed hot exciton emitters with high exciton utilization efficiencies (EUEs) are scarce. Herein, three red emitters, 2TPA, TPAPXZ, and TPAPXZCN, are designed and synthesized. These emitters have large rigid structures and large spin‐orbit coupling between the high‐lying triplet and adjacent singlet states. Photophysical studies show that these emitters exhibit anti‐Kasha high‐lying triplet emissions. Moreover, the MADN host is doped with 5 wt.% of these emitters, which inhibits the internal conversion (IC) rate (kICTn ∼ 108 s−1) of the high‐lying triplet state, making it similar to the high‐lying reverse intersystem crossing (hRISC) rate (khRISC ∼ 108 s−1). It provides a basis for doped devices to achieve high EUEs. Using 2TPA, TPAPXZ, and TPAPXZCN as emissive layers, the doped devices achieve red emission with emission peaks at 628, 626, and 647 nm, respectively. Notably, these devices achieve high EUEs of 43.9%, 81.0%, and 62.6%, respectively. To this knowledge, the EUE of these devices is among the highest values reported for hot exciton material devices. This study provides a novel approach for addressing low EUEs of hot exciton materials and improving their design strategies.

Published: November 2024

AbstractDisplaying the same data in different optical modes has improved both storage capacity and information security. However, it always requires either sophisticated chemistry or expensive experimental setup to build a dual‐mode or even multi‐mode anti‐counterfeiting system. Here, a rewritable dual‐mode pattern is designed, based on the second‐generation Donor‐acceptor Stenhouse adducts decorated polyethylene glycol crystal. Uniform square crystals are obtained through a simple process of controlled solvent evaporation. Complex pattern such as words can be written on the crystals with the help of microregional irradiation. It endows the high‐resolution of the pattern that only the area exposed to light goes through the discoloration and fluorescence change. The great reversibility and fatigue resistance of the photochromism enable the crystals to be repeatedly utilized, making them qualified candidates as high‐level anti‐counterfeiting materials.

AbstractMinimally invasive surgical techniques, including endoscopic and robotic procedures, continue to revolutionize patient care, for their ability to minimize surgical trauma, thus promoting faster recovery and reduced hospital stays. Yet, the suturing of soft tissues ensuring damage‐free tissue bonding during these procedures remains challenging due to missing haptics and the fulcrum effect. Laser tissue soldering has potential in overcoming these issues, offering atraumatic seamless tissue fusion. To ensure the precision and safety of laser tissue soldering, the study introduces feedback‐controlled fluorescent nanothermometry‐guided laser tissue soldering using nanoparticle‐protein solders within endoscopic and robotic contexts. Temperature‐sensitive fluorescent nanoparticles embedded in the solder provide surgeons with immediate feedback on tissue temperatures during laser application, all while within the confines of minimally invasive (robotic) surgical setups. By integrating fluorescent nanothermometry‐guided laser tissue surgery into endoscopic and robotic surgery, the study paves the way for a new approach for safe and atraumatic soft tissue joining, especially in regions where traditional suturing is unfeasible.

AbstractInverted perovskite solar cells (IPSCs) suffer from significant non‐radiative recombination losses at the defective perovskite/C60 interface, limiting the efficiency and stability of perovskite/silicon tandem solar cells. Despite silicon oxide (SiOX) being a common passivation material in the silicon industry with higher electron selectivity than conventional atomic layer‐deposited alumina, its application in IPSCs is limited by its tendency to damage sensitive perovskite during processing. Here, an oblique angle evaporation method is developed to deposit a conformal, ultra‐thin SiOX layer without damaging the underlying perovskite. This SiOX interlayer not only chemically passivates under‐coordinated Pb2+ defects but also forms an n/n+ homojunction that provides effective field‐effect passivation, concurrently reducing recombination and enhancing electron selectivity. As a result, extending this strategy to two‐terminal monolithic perovskite/tunnel oxide passivating contact silicon tandem solar cells achieves a stabilized power conversion efficiency of 30.2%, representing one of the highest efficiencies reported for such tandems. More importantly, the robust inorganic nature of SiOX enables it to serve as a dense inner encapsulation, enhancing both light (ISOS‐L‐1) and thermal (ISOS‐D‐2I) device stabilities.

AbstractPerovskite solar cells (PSCs) commonly suffer from drastic changes in performance over time, dominated by the redistribution of mobile ionic defects. Common characterization techniques for solar cells, such as electroluminescence (EL) imaging, are compromised by transient ionic effects, which makes understanding them important for the device optimization process. This study looks at the shape of EL transients in carbon‐based triple mesoscopic PSCs (CPSCs), which have emerged as a potential solution for increased stability and scalability. The slow changes in EL are explained in terms of the migration of two ionic species with different mobilities, and increased ionic densities over time. The effects of applying a forward bias in the dark and illuminating at open circuit for several hours are found to be similar, both pointing toward an increased mobile ion density which causes current collection efficiency losses without decreasing the radiative recombination yield. Current losses are found to be highly dependent on the ionic distribution, as demonstrated with measurements and simulations of the external quantum efficiency (EQE). The findings explain the commonly observed shape of the EQE in CPSCs and help to further understand the effects of ion migration. Furthermore, this study establishes an effective way to analyze ion‐dominated current losses by measuring low temperature EQE spectra with different preconditioning voltages, which enables to directly compare the effect of different ionic distributions.
Visible Light‐Mediated Radical Decarboxylative Strategies for the Synthesis of Heterocyclic Compounds

Published: November 2024

AbstractHeterocycles are an important structural motif found in many bioactive compounds, natural products and pharmaceuticals. Heterocycles have been synthesised at large employing conventional methods which are usually associated with limitations such as the need for an external oxidant or reductant, harsh reaction conditions, lower selectivity and its unsustainable nature. To circumvent these drawbacks, visible light photocatalysis has emerged as a milder, energetically efficient and environmentally benign tool in organic synthesis. Visible light‐mediated radical decarboxylation of carboxylic acid and its derivatives has been widely explored to affect a wide range of chemical transformation reactions. Redox‐active NHPI derivatives are easily prepared from carboxylic acids which are inexpensive, non‐toxic and stable finding wide applications across various fields. Further, carboxylic acids are one of the most plentiful and renewable feedstock of our planet. Hence, this review brings forth the current developments in the area of visible light‐mediated decarboxylative strategies employing carboxylic acid and its derivatives for the synthesis of heterocyclic compounds.

AbstractChemists around the globe are extensively working for remedial solutions to cancer, one of the greatest health hazards. We have synthesized twenty‐three novel spiro [chromane‐2,4′‐piperidin]‐ 4 ‐one derivatives (KBS and KMS series of analogues) as part of our ongoing research to combat this deadly disease, and confirmed their structures using 1H NMR, 13C NMR, HRMS, and FT‐IR. Furthermore, we employed single‐crystal XRD to identify the compound structures of KBS4 and KMS10. We have tested the compounds on the cell line such as MCF‐7; U87‐MG; SCC‐25; and HEK‐293T, via WST‐1 assay. Eight compounds showed IC50 values ranging 3.9–10 μM; against the cell line MCF‐7. The best compounds of all were KMS9 (IC50=3.83 μM), KMS5 (IC50=4.14 μM), and KBS8 (IC50=8.24 μM), which promoted apoptosis in MCF‐7 cells. KMS5 and KMS9 compounds showed G1 cell cycle arrest, while compound KBS8 showed G2 cell cycle arrest. Insilco ADME studies were carried out. Molecular docking and dynamics experiments showed how KMS5, KMS9, and KBS8 bind to the active region of the EGFR family – a group of receptor tyrosine kinase (RTK) proteins (PDB ID: 7JXP, 2.16 Å). Further structural modifications of the KMS5, KMS9, and KBS8 may improve their activity against breast cancer.
A scoping review of non‐binary research in “Australian” social sciences: Community, solidarity, resilience and resisting marginalisation
Authors: Nicholas Lucy , Clark Sal , Falzon Chloe 
Published: November 2024

AbstractNon‐binary and genderqueer identities are increasingly discussed in public discourse and academia, but there remains a dearth of academic literature centred on non‐binary people's lives and experiences. When non‐binary people are included in research, it is frequently as an additive to explorations of trans identities and subsumed under the trans umbrella or treated as categorically indistinct. Much has been written from a clinical perspective, but the social sciences tend to discuss non‐binary identity conceptually or as a proxy in theoretical arguments. Of the emerging sociological literature on non‐binary identity, much is from the United States or the United Kingdom. Thus, this scoping review engaged with the corpus of research on non‐binary people in “Australia” to consider social change and policy needs. We found much about the negative health impacts resulting from discrimination and barriers, emphasising the structural and systemic nature of the existing gender binary. However, the majority of these papers include a focus on how non‐binary people actively participate in the collective creation of community, identity and safe spaces for affirmation. Resilience, coping strategies and solidarity were key themes and offer important insights into how the barriers identified can be ameliorated.

AbstractBackgroundMedian arcuate ligament syndrome describes a clinical presentation associated with direct compression of the celiac artery by the median arcuate ligament. Decreased blood flow from the celiac artery and increased flow from superior mesenteric artery causes blood flow in the pancreatic arcade to increase, and aneurysms can form. We report our experience with six cases of retroperitoneal hemorrhage induced by median arcuate ligament syndrome in patients during the COVID‐19 period.Case PresentationThe time from the onset of COVID‐19 to that of abdominal pain in the patients ranged from 3 to 9 days. None of the patients required oxygen for COVID‐19. We used contrast‐enhanced computed tomography to diagnose retroperitoneal hemorrhage and formation of a visceral pseudoaneurysm or aneurysm due to median arcuate ligament syndrome. Five patients underwent transcatheter arterial embolization. One patient suffered complications of duodenal stenosis and another suffered portal vein thrombosis.ConclusionsRetroperitoneal hemorrhage associated with median arcuate ligament syndrome is rare. However, it might be triggered by COVID‐19 disease, resulting in arterial disruption and hemorrhage.

AbstractHere we report the reaction of aryl thianthrenium salts that allows selective functionalization of the meta position of arenes. The combination of a site‐selective thianthrenation with a Catellani reaction provides access to 3,5‐dimethylated arenes. The developed reaction is complementary to the previously discovered reductive ipso‐alkylation of aryl thianthrenium salts and extends the possibilities for late‐stage methylation of arenes with a single aryl thianthrenium salt.
Sb‐to‐P Metathesis: A Direct Route to Structurally Constrained, Cationic PIII Compound
Authors: Bawari Deependra , Malahov Irina , Dobrovetsky Roman 
Published: November 2024

AbstractStructurally constrained, cationic PIII compound [LP][SbCl4] with an OCO pincer‐type ligand (L) having a central carbene donor was directly synthesized via an Sb‐to‐P metathesis reaction between PCl3 and LSb‐Cl. [LP][SbCl4] was isolated and its reactivity with small molecules (ROH and RNH2) was studied, showing that [SbCl4]− is not an innocent counter anion, but an active participant in these reactions. When the [SbCl4]− was replaced with the [CB11H12]− ([Cb]−) anion, the reactions were redirected to [LP]+ cation only. The reactions with alcohols and amines led to the equilibrium between the products of the formal E−H (E=O, N) bond oxidative addition to the P‐center and products of the P‐center/ligand‐assisted bond activation. Remarkably, [LP]+ activated the PhO−H and PhN(H)−H bonds in a reversible, thermoneutral fashion.
