Kagome lattices, characterized by corner-sharing triangles, are a notable class of materials featuring the coexistence of flat and Dirac bands. This study investigates a new class of carbon lattices derived from cyclacene molecules (cyc-CL), featuring a distorted hexagonal tiling. In these two-layer carbon structures with hydrogen-saturated bonds, π orbitals lie parallel to the layers, unlike typical 2D carbon materials. Using first-principles DFT calculations, we analyze three variants (6-cyc-CL, 12-cyc-CL, and 18-cyc-CL), examining band gaps, density of states (DOS), and orbital contributions. Cyc-CL systems exhibit tunable band gaps, flat and Dirac bands near the Fermi level, and dominant π orbitals from p x and p y states. These results highlight cyc-CL's potential for studying quantum phenomena and enabling nanotechnology applications.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12288019/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144732079","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}

They self-assemble into cargo-loaded protein shells between ca. 20 and 50 nm in diameter with either T = 1, T = 3 or T = 4 icosahedral symmetry. Encapsulin nanocages possess several key features that make them an attractive engineering platform for creating nanocarrier-based drug delivery systems. This includes a modular and efficient cargo loading mechanism for the facile encapsulation of proteins of interest, diverse physicochemical characteristics and high stability, and robust genetic and chemical strategies of shell modification. For these reasons, encapsulins have garnered significant interest as platforms for various engineering ventures in biomedicine and biotechnology. In this review, we summarize recent advances in engineering encapsulins for drug delivery applications, highlighting their engineerability as a platform technology, innovative strategies employed to enhance their therapeutic potential, and recent concrete drug delivery applications based on engineered encapsulin nanocarriers.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12285755/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144732080","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}

Thirteen bisphosphonates (BPs), including risedronate (RSD), were tested for their sorption capacity and release behavior in simulated body fluid (SBF). Sorption studies revealed that BPs with iodine, methyl, and benziothiazole groups (BP5, BP6, and BP12) exhibited high sorption rates (>50%), while compounds containing bromine or chlorine displayed lower sorption capacities. Release experiments demonstrated that RSD, BP5, and BP6 followed a sustained release profile, while BP12 showed an initial burst followed by a tapering release. The density functional theory (DFT) calculations provided further insight into the adsorption mechanisms, highlighting the role of dispersion interactions and electrostatic bonding with calcium ions. The use of zeolite carriers reduced the toxicity of drugs towards human fibroblast BJ cells. The effect of the carrier addition on osteosarcoma 143b cells was also determined; some of the drugs did not lose their activity in relation to them after being placed on the carrier. These findings suggest that calcium-exchanged zeolite carriers can effectively facilitate the controlled release of BPs, offering potential for applications in osteoporosis treatment by maintaining therapeutic levels over extended periods.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 15","pages":" 5269-5285"},"PeriodicalIF":5.2,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00371g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716353","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 currently employed fabrication methods often involve mechanical assembly, which can introduce defects and limit scalability. Herein, we demonstrate a scalable approach to grow lattice-matched h-BN on graphene via metal–organic chemical vapor deposition with a flowrate-modulated epitaxy method. TEM analysis revealed the successful growth of 7 to 8 layers of h-BN on the substrates. Notably, vdWHT h-BN/graphene exhibited superior optical and structural properties compared with h-BN/sapphire. This was evident in the results of UV-Vis and Raman spectroscopies and SEM analysis. Moreover, vdwHT h-BN/graphene demonstrated significantly enhanced DUV sensing performance at 254 nm, with an excellent on/off ratio exceeding 110 compared with the ratio of 3.8 of h-BN/sapphire. These findings underscore the importance of lattice matching in optimizing the properties of h-BN-based heterostructures. The successful fabrication of high-quality vdwHT h-BN/graphene heterostructures opens a new avenue for the development of advanced DUV sensing devices and other 2D applications.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 15","pages":" 5260-5268"},"PeriodicalIF":5.2,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00044k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716352","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}

Symmetric devices (BMO//BMO) exhibit a higher specific capacity (∼83 mAh g−1), but lower retention (∼36% after 1250 cycles), while asymmetric devices (BMO//carbon nanotubes (CNTs)) show superior retention (∼85% after 2500 cycles) with a capacity of ∼46.25 mAh g−1. The enhanced redox activity in symmetric format contrasts with the conductive benefits of CNTs in asymmetric systems. This dual evaluation demonstrates the versatility of BMO for both energy density and long-term stability, making it a promising material for high-performance energy storage applications. Furthermore, we provide a detailed analysis of the charge storage mechanism of BMO, which follows a battery-type process driven by intercalation and redox reactions, resulting in its high capacity. The practicality of the BMO//BMO device is demonstrated by lighting red, green, and blue LEDs for 18 minutes, 45 seconds, and 30 seconds, respectively, using two identical supercapacitor cells connected in series.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 15","pages":" 5310-5323"},"PeriodicalIF":5.2,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00647c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716380","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}

The distinct dual-mode photoresponse arises from the complementary absorption characteristics of CQDs and indigo molecules. Specifically, negative photoconductivity (NPC) is observed under ultraviolet (UV) excitation, while exposure to visible light induces positive photoconductivity (PPC). The transition from NPC to PPC is governed by wavelength-dependent mechanisms involving charge carrier recombination, competitive trapping of photo-excited electrons in defect states associated with CQDs, and the efficient generation of electron–hole pairs within the indigo molecular framework. Notably, the switching between PPC and NPC is fully controlled by the excitation wavelength without any change in device configuration or bias polarity. Under UV illumination at 275 nm, the device exhibits high responsivity (R = 1947.66 mA W−1), an ON/OFF ratio of 5.82, and enhanced detectivity (D* = 3.94 × 1014 Jones). Furthermore, both PPC and NPC modes demonstrate significant improvement in detectivity compared to previously reported organic and many inorganic photodetectors. This dual-mode photoconductive behavior in a single device architecture not only enables spectral selectivity but also paves the way for multifunctional optoelectronic applications. The CQD–indigo composite is thus a highly promising active material for broadband photodetection, optoelectronic memory, and neuromorphic device platforms.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 15","pages":" 5210-5220"},"PeriodicalIF":5.2,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00439j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716348","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}
