In this work, we flexographically print films from an ink of Sepia melanin including shellac as a bio-sourced binder on silver electrode-patterned paper. We examine the electrical response in high humidity and ambient conditions (here the electronic conductivity is as high as 10−4 S/cm). Additionally, we study the biodegradation of the printed films and their individual constituents based on their mineralization into CO2 under composting conditions. The printed films exhibit biodegradation levels of about 97 ± 25% in 85 d. We observe microorganism colonization on the printed film’s surface. The analysis of the microbial community on the compost reveals that bacterial species within the Acidimicrobiia class, specifically Actinomarinales order, are potentially responsible for the biodegradation of the printed film. Meanwhile, ecotoxicity tests conducted by germinating Lolium multiflorum and Tagetes erecta suggest that printed films have negligible phytotoxicity. Sepia melanin, a biopigment extracted from cuttlefish ink, shows promise for sustainable organic electronics.

Accounting for a substantial percentage of malignant bone tumors, osteosarcoma particularly affects children and adolescents. Despite standard treatment combining surgery and multi-drug chemotherapy, systemic drug administration presents limitations, leading to compromised patient quality of life and severe side effects. New strategies are needed to address these challenges and enhance efficacy while minimizing toxicity. Here, we explore drug delivery platforms in the context of osteosarcoma treatment. We delve into both systemic and local delivery approaches, highlighting recent advances in controlled drug release triggered by various stimuli, modifications for targeted delivery, and co-delivery of chemotherapeutics using nano-platforms. Additionally, we discuss innovations in local delivery methods, including implantable nanoparticles, injectable hydrogels, and scaffolds. Despite these advancements, challenges and limitations persist, emphasizing the need for continued research. We conclude by offering perspectives on the potential of multifunctional scaffolds in revolutionizing osteosarcoma drug delivery, thereby paving the way for improved patient survival and enhanced quality of life. Drug delivery platforms are needed for combatting osteosarcoma, which accounts for a large proportion of malignant bone tumors. This Review highlights recent progress in drug delivery methods, including systemic nanoparticle-based drug delivery and local strategies such as nanoparticles, hydrogels, and scaffolds, while addressing ongoing challenges and future research needs.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":null,"pages":null},"PeriodicalIF":7.5,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43246-024-00612-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142091180","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}

However, the effects of spin-orbit coupling on these materials have not yet been fully explored. Here, we show that single- and double-bilayer antimony honeycomb lattices, referred to as antimonene, form moiré superlattices on a Bi(111) substrate due to lattice mismatch. Scanning tunnelling microscopy (STM) measurements reveal the presence of spectral peaks near the Fermi level, which are spatially modulated with the moiré period. Angle-resolved photoemission spectroscopy (ARPES) combined with density functional theory calculations clarify the surface band structure with saddle points near the Fermi level, which allows us to attribute the observed STM spectral peaks to the van Hove singularity. Moreover, spin-resolved ARPES measurements reveal that the observed surface states are Rashba-type spin-polarized. The present work has significant implications in that Fermi surface instability and symmetry breaking may emerge at low temperatures, where the spin degree of freedom and electron correlation also play important roles. Moiré superlattices are of great fundamental interest as they can host emergent phenomena such as flat band-induced Mott insulating states and unconventional superconductivity.

Here, we introduce the 1-(4-Fluorophenyl)−2-pyrrolidone molecule (FPP) as additive in large-area blade-coating perovskite films. During the top-down crystallization process, the FPP molecule form an intermediate phase with the perovskite components and subsequently self-deposit at the bottom surface. Consequently, the crystallization kinetics of the large-area thin films are regulated, and the bottom surface is effectively and uniformly passivated in one single-step processing. By employing this self-deposited passivation method (SDP), the efficiency decrease caused by the expansion of the device area has been significantly suppressed and the devices yield power conversion efficiency of 23.41% (0.09 cm2), 22.43% (1 cm2), and 20.75% (24 cm2). The method is compatible for commercial manufacturing with scaling up solar cell area and holding high efficiency.

Silicon experiences large volume changes upon the Li-insertion and extraction, leading to the amorphization of the silicon-interface due to the permeation of the Li-ions into the silicon. Here, we discover how generated non-hydrostatic strain upon electrochemical cycling further triggers dislocation and eventually shear band formation within the crystalline silicon core. The latter boosts the non-uniform lithiation at the silicon interface affecting the SEI reformation process and ultimately the capacity. Our findings are based on a comprehensive multiscale structural and chemical experimental characterization, complemented by molecular dynamics modelling. This approach highlights the importance of considering electrochemical, microstructural and mechanical mechanisms, offering a strategy for developing improved anode materials with enhanced cycling stability and reduced capacity loss.

This engineering involves precise host and dopant material composition, yielding nanocrystals with sharply peaked photoacoustic absorption spectra (~3.2 nm width) and a ~10-fold enhancement in NIR optical absorption for efficient deep tissue imaging. By combining photoacoustic tomography with these engineered nanocrystals, we demonstrate photoacoustic multiplexed differential imaging with substantially decreased background signals and enhanced precision and contrast.

The high-entropy approach is thus quite promising, as it offers the possibility of a delicate tuning of chemical disorder. In this work, we investigate the entropy-stabilized pyrochlore compound Tb2(TiZrHfGeSn)2O7. We report the lack of long range magnetic order, yet the observed magnetic diffuse scattering is characteristic of antiferromagnetic first-neighbor correlations. The crystal field excitation spectrum, with broaden levels, visibly reflects the smooth environmental disorder of the Tb environment. The low energy dynamics are characterized by a narrow mode at about 0.4 meV, consistent with specific heat. Remarkably, as illustrated by a model of random isotropic shifts of oxygen atoms around Tb ions, the spectral weight of this mode is a direct consequence of deviations from the D3d symmetry at Tb sites. In the light of these results, quadrupolar interactions are also discussed. Frustrated magnetic systems such as pyrochlores are interesting for the complexity of their competing low-temperature phases. Here, the intrinsic disorder of the entropy-stabilized compound Tb2(TiZrHfGeSn)2O7 is utilized to investigate the elusive ground state of Tb-based pyrochlore magnets.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":null,"pages":null},"PeriodicalIF":7.5,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43246-024-00589-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142021839","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}
