This is especially true for the simulation of open quantum systems, which involve additional units and operations to map environmental degrees of freedom. Hence, finding efficient approaches for the simulation of open quantum systems is an open issue. In this work, we demonstrate how using units with d > 2 levels (qudits) results in a reduction of up to two orders of magnitude in the number of operations (gates) required to implement state-of-the-art algorithms. We explore two conceptually distinct families of these algorithms that were initially designed for qubits and discuss the gate complexity scaling that different platforms (qubit-based vs. qudit-based) offer. Additionally, we present realistic simulations of an experimental platform based on molecular spin qudits coupled to superconducting resonators, where the main hardware error sources are included. We show that, in all cases considered, the use of qudits leads to a remarkable reduction in circuit complexity and that molecular nanomagnets are ideal qudit hosts.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of effective remote control and reliance on a single actuation method pose significant challenges, limiting its applications in various fields. This study aims to address these limitations by developing a novel multi-responsive nanocomposite. By coating near-infrared light (NIR)-responsive polypyrrole (PPy) onto the surface of magnetic iron oxide (Fe2O3) nanoparticles (NPs), multi-responsive PPy@Fe2O3 NPs were synthesized. Doping PPy@Fe2O3 into a thermo-responsive shape memory polymer (SMP) matrix created a nanocomposite with excellent NIR and magnetic responsiveness, enabling dynamic, remote-controlled shape transformation of printed objects with precise timing and positioning using NIR and a magnetic field. Using the nanocomposite, a proof-of-concept semi-tubular construct was fabricated to evaluate its controllable transformation capability and assess the potential for modulating neural stem cell (NSC) behaviors. Furthermore, three proof-of-concept smart robots with distinct features were designed and fabricated for cargo delivery in diverse scenarios and different purposes. Importantly, all complex operations of these robots were remotely controlled using NIR illumination and an external magnetic field. This novel approach demonstrates significant progress in addressing the key challenges of remote control and actuation in 4D printing, highlighting its potential for enhanced versatility and functionality across various applications.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the use of Kapton® in spacesuits dates back to the two aluminised Kapton® layers used in the spacesuits in the Apollo 11 mission, the potential uses of polyimides in the design of spacesuits remain underexplored, particularly considering the advancement made in the development of high-performance polyimide-based composites. This review explores the opportunities that emerge when the desirable properties of polyimides are combined with that of nanomaterials, specifically carbon nanomaterials, to produce strategic material combinations that promise to achieve enhanced thermal and mechanical properties, improved resistance to abrasion and puncture, and potentially reduced weight compared to traditional spacesuit materials.

Carbon-fluorine bonds in the main chains of fluoropolymers impart fluoroplastics with chemical inertness and low surface energy. Achieving effective surface wettability and strong adhesion to fluoroplastics is difficult for adhesive materials because of the lack of cohesion affinity and interfacial interactions. The key to the tough adhesion on fluoroplastics lies in realizing good wettability and high compatibility to surface-fluorinated substrates. Here, a new strategy is developed to address the adhesion challenges to fluoroplastics. The dynamic polymerization and cross-linking of thioctic acid and tetrafluorophthalic acid generate multiple fluorine-fluorine interactions and fluorohydrogen bonds, thus facilitating supramolecular adhesives with strong interfacial interactions to fluoroplastics. The macroscopic bulk state, good mechanical toughness, high cohesion energy density, and rapid self-healing capacity originating from non-covalent assembly provide the necessity for effective and long-term stable adhesion to fluoroplastics. This strategy demonstrates that an application-oriented material design is practical for fluoroplastics adhesion.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in a conventional design, the NO3-RR is often coupled with the anodic oxygen evolution reaction, leading to substantial energy consumption while yielding low-value oxygen. Here, we report a hybrid electrolysis system that combines cathodic reduction of nitrate to ammonia and anodic oxidation of polyethylene-terephthalate-derived ethylene glycol (EG) to formic acid (FA), utilizing oxygen-vacancy-rich (OV) Co3O4 and Cu doped Ni(OH)2 as the cathode and anode, respectively. Remarkably, this paired electrolysis system demonstrates a faradaic efficiency (FE) of 92% for cathodic ammonia production and a FE of 99% for anodic FA production, while reducing the cell voltage by 0.54 V compared to the conventional NO3-RR system at the same current density of 100 mA cm-2. Experimental investigations combined with theoretical calculations reveal that the OV introduction effectively addresses the insufficient NO3- adsorption and hydrogenation on bare Co3O4. Additionally, Cu incorporation increases the Ni-O covalency, resulting in an improved EG adsorption ability. This work presents a promising way for waste management via paired electrolysis.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various methods have been developed to combat melanoma, with photodynamic therapy (PDT) gaining the spotlight for its ability to eliminate cancer cells by generating reactive oxygen species through light-sensitive photosensitizers. 5-aminolevulinic acid (5-ALA) is the most commonly used PDT agent, which could be converted to the PpIX photosensitizer molecule within cancer cells. However, its high hydrophilicity limits effective transdermal and oral delivery. In this work, we present a novel polymer formulation, named 5-AP, designed for the transdermal delivery of 5-ALA to deep melanoma tumor sites. 5-AP was prepared by the in situ polymerization of dimethylsiloxane, using 5-ALA as a photosensitizer precursor and a ring-opening polymerization initiator. 5-AP exhibited enhanced hydrophobicity compared to 5-ALA, facilitating improved transdermal penetration. In a melanoma mouse model, 5-ALA was released from the polymer and then converted to PpIX, emitting fluorescence and demonstrating high tumor treatment efficacy under laser irradiation.

Conversely, low-toxicity perovskite-inspired materials (PIMs) typically exhibit suboptimal optoelectronic performance, primarily due to their intrinsic susceptibility to defects. In this study, we address this limitation by exploring the effects of halide vacancies in PIMs through the synthesis of non-stoichiometric Cs3Bi2Br3I5.2 microcrystals (MCs) with a trigonal crystal structure, incorporating iodine vacancies. Density functional theory simulations reveal that these iodine vacancies introduce benign mid-gap states that facilitate charge transport without perturbing band-edge excitons. As a result, the MCs exhibit sharp photoluminescence emission with a linewidth of 140 meV and a minimal Stokes shift of 147 meV, indicative of efficient band-edge recombination. Transient absorption measurements confirm photo induced mid-gap absorption, while space charge limited current measurements demonstrate low trap densities of 1.1 × 1011 cm-3, despite the presence of iodine vacancies. We further fabricated self-driven broadband photodetectors using 2D-Cs3Bi2Br3I5.2 MCs, achieving a high responsivity of 0.9 A W-1 with a photoresponse extending to 800 nm. While ultrafast carrier localization remains a performance-limiting factor, the room-temperature carrier mobility exceeds 1 cm2 V-1 s-1, positioning Cs-Bi-Br-I as a highly promising low-toxicity absorber for advanced optoelectronic and light-harvesting applications.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We demonstrate the conversion of mixed polyolefin wastes into structured carbon with exceptional Joule heating properties using fused filament fabrication (FFF) printing, crosslinking, and pyrolysis. This waste-derived carbon serves as both a catalyst support and heating element for electrified hydrogen production via ammonia decomposition. This Joule heating-enabled process leads to enhanced intrinsic catalytic activity and demonstrates accelerated reaction start and shutdown speeds compared to the convection heating method, while having the advantage of reducing global warming and life cycle energy consumption impacts.
