Here, we address this limitation by developing the first hierarchically porous honeycomb aerogels that replicate hexagonal pores at both the macro-level and micro-level wall structure. This design, inspired by nature's most efficient patterns, enables us to achieve CO₂ adsorption capacity (3.94 mmol g-¹ at 298 K and 1 bar), selectivity (65.2 CO₂/N₂), and high specific surface area (370 m² g-¹). The honeycomb aerogels are constructed from manganese dioxide (MnO₂) functionalized electrochemically exfoliated graphene (MEEG) and chitosan (CS). By optimizing the MnO₂ loading and the MEEG to CS weight ratio, we achieved dual-scale hexagonal porosity, enabling a hybrid physical and chemical adsorption mechanism. The hybrid adsorption leverages the rapid kinetics of chemisorption and ease of regeneration characteristic of physisorption, making these materials highly efficient. This highlights the synergy between enhanced surface accessibility of primary amine groups and selective adsorption properties, setting a new standard for hierarchically structured materials.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":"6 1","pages":"130"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12221977/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic skyrmion lattices, in particular, host a manifold of topological magnon bands with multipole character and non-reciprocal dispersions. These modes have been explored already in the short and long wavelength limit, but previously employed techniques were unable to access intermediate wavelengths comparable to inter-skyrmion distances. Here, we report the detection of such magnons with wavevectors ∣q∣ ≃ 48 rad μm-1 in the metastable skyrmion lattice phase of the bulk chiral magnet Cu2OSeO3 using Brillouin light scattering microscopy. Thanks to its high sensitivity and broad bandwidth various multipole excitation modes could be resolved over a wide magnetic field regime. Besides the known counterclockwise, breathing and clockwise modes with dipole character, quantitative comparison of frequencies and spectral weights to theoretical predictions enabled the additional identification of a quadrupole mode and, possibly, a sextupole mode. Our work highlights the potential of skyrmionic phases for the design of magnonic devices exploiting topological magnon states at GHz frequencies.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":"6 1","pages":"139"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12227311/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While characterization of this correlated phase is well established via real or reciprocal space techniques, for systems where the mechanisms interplay, a macroscopic approach becomes necessary. Here, we demonstrate the application of polarization-resolved high-harmonic generation (HHG) spectroscopy to investigate the correlated CDW phase and transitions in TiSe₂. Unlike previous studies focusing on static crystallographic properties, the research examines the dynamic reordering that occurs within the CDW as the material is cooled from room temperature to 14 K. By linking ultrafast field-driven dynamics to the material's potential landscape, the study demonstrates HHG's unique sensitivity to highly correlated phases and their strength. The findings reveal an anisotropic component below the CDW transition temperature, providing insights into the nature of this phase. The investigation highlights the interplay between linear and nonlinear optical responses and their departure from simple perturbative dynamics, offering a fresh perspective on correlated quantum phases in condensed matter systems.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":"6 1","pages":"152"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12270906/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144674037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, delivering drugs across the blood-brain barrier is an active research area in immunology, oncology, and neurology; moreover, novel methods are urgently needed to expand therapeutic options for central nervous system pathologies. While previous strategies have focused on small molecules that modulate blood-brain barrier permeability or penetrate the barrier, there is an increased focus on biomedical devices-external or implanted-for improving drug delivery. Here, we review device-assisted drug delivery across the blood-brain barrier, emphasizing its application in glioblastoma, an aggressively malignant primary brain cancer in which the blood-brain barrier plays a central role. We examine the blood-brain barrier and its features in glioblastoma, emerging models for studying the blood-brain barrier, and device-assisted methods for crossing the blood-brain barrier.

We explore photoswitchable diacylglycerophospholipids, termed 'photolipids', which permit precise, reversible modifications of membrane properties via light-induced isomerization. The ability to optically switch phospholipid properties has potential applications in controlling membrane dynamics, protein function, and cellular signaling pathways, and offers promising strategies for drug delivery and treatment of diseases.

We find that the long-range magnetic order gives rise to a very rich ARPES signal, which can only be interpreted with a proper first-principles description of the SDW and CDW, combined with a band unfolding procedure, reaching a remarkable agreement with experiments. Additional features of the SDW order are obscured by superimposed effects related to the photoemission process, which, unexpectedly, are not predicted by the free-electron model for the final states.
