In such cases, oxidative stress introduces two primary challenges that impede the healing process: ensuring the directional movement of functional cells to the wound site and combating the heightened risk of infection. These challenges underscore the need for innovative therapeutic strategies that can effectively address these restrictions in the context of diabetic wound healing. Hydrogen sulfide (HS) acts as a signaling gas and shows significant therapeutic potential in biomedical research. In this study, we encapsulate Allicin, a natural HS donor, in selenium micelles that specifically respond to oxidative stress. To create the GMA (Allicin@Micelle-GelMA) Composite hydrogel system, we utilize Methacrylic anhydride gelatin (GelMA) hydrogel as a matrix and form it through in-situ light curing. This composite system effectively addresses the problem of healing deep, narrow, and lengthy wounds that pose a challenge, as well as preventing nonspecific sudden release of HS. Additionally, the composite hydrogel system promotes angiogenesis, anti-inflammatory, antibacterial, and antioxidant properties. It also facilitates the directional movement of stem cells and macrophages, as demonstrated through the chicken embryo chorioallantoic membrane vascular test and the establishment of a diabetes wound model that is difficult to heal. Consequently, we conclude that the GMA composite hydrogel has the potential to serve as a versatile skin wound dressing that can effectively respond to oxidative stress.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"2 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178317","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}

Herein, white β-BaScAlO: Yb, Er (β-BSAO-YE) phosphor was irradiated with 254 nm light, which caused the phosphor to turn blue due to the increase of oxygen vacancy. The blue β-BSAO-YE phosphor returns to its original color upon stimulation with 808 nm laser light or 125 °C, exhibiting a double photo-induced reversible photochromic change. The green and red upconversion luminescence (UCL) of the β-BSAO-YE were reversibly modified according to their photochromic properties. The UCL modification changes the luminescence color of the pattern, indicating that β-BSAO-YE phosphor is an ideal compound anti-counterfeit agent. The light information recorded on the β-BSAO-YE binary photochromic dot matrix can be read under ultraviolet (UV) and near-infrared (NIR) excitation, demonstrating the potential application of β-BSAO-YE phosphors as optical data storage media. In addition, the cyclic experiment showed good photochromic and UCL modulation repeatability. The new luminescent β-BSAO-YE not only proposes a new way to exploring upconversion red light materials, but also provides new materials for optical storage, optical information and optical anti-counterfeiting.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"13 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178318","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}

This is especially true in the case of magnetically actuated swarms, which can be remotely manipulated with high precision also in-vivo. The manufacturing and the collective actuation of a large number of devices, however, is a challenging task and it requires the development of highly tailored, adaptable and low cost strategies. In the present work, we demonstrate that a combination of inkjet assisted lithography (IAL) and electroforming can be a high-throughput, scalable and low-cost fabrication method for the production of disk-shaped ferromagnetic micromotors. Thanks to the versatility of the hybrid manufacturing technique developed, the diameter and the thickness of the devices can be easily controlled and tailored according to the target application. In addition, the use of electroforming makes possible the manufacturing of soft or hard magnetic devices, whose magnetization direction can be programmed. In the specific case, Ni and CoNiP devices were produced, characterized and actuated in swarms composed of hundreds of individuals. According to their magnetic properties, the devices exhibited highly controllable actuation patterns with multiple degrees of freedom. In order to provide an applicative perspective, the ferromagnetic micromotors were coated with polypyrrole and employed for drug delivery, evidencing thus their capability to load and release the model molecule Rhodamine B.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"19 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178319","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}

Herein, an injectable nanocomposite hydrogel platform is designed via encapsulating calcined MgMnFe-layered double hydroxide (LDH250) nanosheets and cisplatin into gelatin/hyaluronic acid double-crosslinked hydrogel. As an inducer of Fenton/Fenton-like reactions, LDH250 nanosheets exhibit multiple redox cycling pairs (Mn/Mn/Mn, Fe/Fe) capable of generating abundant reactive oxygen species (ROS), which synergizes with cisplatin to kill tumor cells effectively. Apart from this, the converse reaction of Mn into Mn allows LDH250 to consume GSH and produce O, thereby avoiding the deactivation of ROS and cisplatin, as well as alleviating hypoxia. These characteristics of LDH250 boost the anti-tumor effect of cisplatin and can be enhanced by modulating the calcination temperature. Furthermore, the hydrogels can reduce the transportation distance of ROS in chemodynamic therapy (CDT) and regulate the release of cisplatin. Based on these tactics, the nanocomposite hydrogel platform exhibits effective antitumor efficacy and .

Traditionally, NWs are grown using seed sintering on rigid substrates at high-temperature. However, the rise of flexible electronics, which use substrates unable to withstand high temperatures, has shifted focus to metal-assisted synthesis methods that do not require high-temperature sintering. This method has gained increasing attention due to its compatibility with flexible substrates. This article focuses on understanding the underlying growth mechanisms and achieving controlled growth of ZnO NWs on metal seeded flexible substrates. Furthermore, a parametric analysis is carried out to elucidate the correlation among different growth conditions in the chemical bath deposition (CBD) technique. Through a meticulously planned experimental design, the study investigates the influence of different growth conditions on synthesis outcomes. This leads to the formulation of predictive models using advanced machine learning (ML) methods particularly, artificial neural network (ANN). Following validation and training, the ANN model exhibits a remarkable ability to predict synthesis outcomes, yielding R values of 0.92 for diameter and 0.96 for length of NWs. Notably, the highest aspect ratio (AR) of ∼24 is attained following the growth conditions: 25 mM precursor concentration, 60 min growth time, and a growth temperature of 95 °C. Additionally, this method of growing ZnO NWs on a metal-seeded substrate offers an alternative approach for fabricating nanodevices for various emerging applications.","PeriodicalId":8066,"journal":{"name":"Applied Materials Today","volume":"14 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178324","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}

Such unique feature allows them to adapt to various needs and offers new opportunities in several application fields, enabling them to overcome the limitations of traditional materials. The present paper aims to introduce readers to the world of programmable materials, enhance their interest, knowledge, and skills in the field, and provide useful insights and new ideas on how to approach their development and implementation. Accordingly, this paper offers an overview and discussion of current state-of-the-art and recent progress up to future perspectives. First, the historical evolution and definition of these materials as well as the types of programmable properties achievable are presented. Then, the different programming strategies that could be used to tune material properties are covered, with an emphasis on the constituent materials, applied stimuli, and geometrical arrangements.

The effect of nanocomposite processing on electromagnetic properties was evaluated by varying the mixing protocol, either through direct extrusion with simultaneous addition of all constituents or by preparing a master batch followed by dilution. The impact of nanofiller morphology and processing techniques on the behavior of nanocomposites was systematically investigated. Filaments of these nanocomposites were Additive Manufactured via Material Extrusion, and the resulting parts were evaluated for EMI shielding effectiveness (SE) in the X-band frequency range. The study reveals that the morphology, influenced by the processing strategy, significantly impacts the EMI SE properties of the printed samples. Particularly, ternary hybrids 3/3/3 wt% (CNT/GNP/CB) nanocomposites demonstrate promising electrical (0.003 S/cm), electromagnetic (29 dB of total attenuation), and mechanical performance (elastic modulus of 3080 MPa), with a clear advantage observed in those processed via direct extrusion. These nanocomposites were validated as feedstock filaments for 3D printing, and the printed sample exceeds the injection molded behavior for the composition 3/3/3 wt% (CNT/GNP/CB), achieving 40 dB of total attenuation at 11.8 GHz.
