Here, we demonstrate significantly enhanced high-temperature mechanical properties of Inconel 625 (In625) based metal matrix composites (MMCs) fabricated by laser powder bed fusion (LPBF) additive manufacturing. The MMC feedstocks for LPBF were fabricated with fine ceramic particles (i.e., titanium diboride (TiB<sub>2</sub>), titanium carbide (TiC), zirconium diboride (ZrB<sub>2</sub>) and zirconium carbide (ZrC)) separately mixed with In625 powders. Among the printed specimens, the In625 + TiB<sub>2</sub> showed an exceptional strength-ductility combination at 800 °C as well as an outstanding creep resistance at 800 °C under 150 MPa tensile stress. The detailed microstructural characterization, along with thermodynamic calculation and atomic simulations, reveal that the addition of TiB<sub>2</sub> results in the formation of serrated grain boundaries, (Cr, Mo)-boride phases near the grain boundaries, and nano-dispersed (Ti, Al, Nb)-oxide phases within the matrix. These features effectively suppress the formation of detrimental high-temperature phases and enhance the material’s high-temperature properties. Beyond amplifying the inherent thermal attributes of In625 superalloy, the research highlights the transformative potential of boride doping and the composition design of MMCs specifically for the LPBF process.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"80 ","pages":"Pages 297-307"},"PeriodicalIF":21.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142721082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Removing toxins and leaving behind albumin is an arduous task in the field of blood purification. Inspired by the dissociation-transportation process of protein-bound toxins in renal tubule, we propose multi-point photodecomposition accompany with adsorption strategy as a novel treatment modality in hemoperfusion. As a proof of concept, bilirubin is chosen as the research object since it is a typical protein-bound toxin that needs to be transported by strong binding to albumin in blood environment. Interestingly, blue light can efficiently break bilirubin into some highly polar water soluble diazo compounds, the decomposed products of bilirubin are water-soluble and loosely bound to albumin. Herein, graphene quantum dots (GQDs) and polymer science are combined in the nanoarchitectonics processes. The “photodecomposition-adsorption” platform is designed by embedding GQDs in poly (diallyldimethylammonium chloride-acrylamide) (poly (DDAC-AAm) hydrogel (PDMG) microspheres. In order to reduce the influence of cationic polymer on blood component, hyaluronic acid (HA) are coated on the surface of the PDMG (PDMG@HA) microspheres by electrostatic interaction. Owing to the luminescence property of GQDs, the PDMG@HA microspheres emit blue light under ultraviolet activation and decompose bilirubin into water soluble diazo compounds, just like numerous “blue bulbs”. The water-soluble bilirubin debris could be dissociated from albumin and adsorbed by “blue bulbs”, which greatly reduce the metabolic burden on the body. In vitro biocompatibility results demonstrate that the PDMG@HA microspheres show lower protein adsorption and blood cell toxicity than the PDMG microspheres. The photodecomposition and adsorption amount of bilirubin is 187.8 mg/g <em>in vitro</em>. In hyperbilirubinemia rabbit hemoperfusion, the “blue bulbs” remove 70.9 % total bilirubin (TBIL) from plasma and defer the liver damage of biliary obstruction. Notably, the bilirubin photodecomposition is persisted to the end of the treatment, and some of the bilirubin debris have been adsorbed by the “blue bulbs”. The strategy combining both photodecomposition and adsorption opens a new route for the treatment of blood-related diseases.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"80 ","pages":"Pages 327-341"},"PeriodicalIF":21.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, further amplification of the sustained immune response remains challenging. Herein, by selecting from typical metal anions, we confirmed the significant cytotoxicity and pyroptosis induction potency of vanadate anions, owing to the inhibition of ATPases and disruption of intracellular ion homeostasis. Then, PEGylated bimetallic manganese vanadate nanoparticles (MnVO<sub>x</sub>) were synthesized for stimulator of interferon genes (STING) pathway-boosted pyroptosis therapy. The vanadate produced from MnVO<sub>x</sub> degradation inhibited membrane ATPases and induced potassium efflux and calcium overload, resulting in inflammasome activation, mitochondrial damage, and endoplasmic reticulum stress, as well as subsequent robust pyroptotic cell death. The released manganese ions stimulated STING pathway through dendritic cells maturation and type I interferon secretion. This dual strategy triggered strong anti-tumor immunity and promoted immune cell infiltration into the tumor, which further defeated distant tumors in combination with immune checkpoint blockade (ICB) therapy. Moreover, by dispersing MnVO<sub>x</sub> with lipiodol for interventional transarterial embolization (TAE) therapy, an enhanced therapeutic efficacy was achieved in orthotopic rabbit liver cancer compared to that of lipiodol alone.

We focus on gallium telluride, which is comprised of highly distorted quadruple-layer slabs and zigzag-shaped vdW gaps. By carrying out continuous rolling experiments, we prove that gallium telluride exhibits excellent deformability with high fracture resistance. The plastic deformation in this monoclinic crystal is mediated by both inter-layer slips and cross-layer slips, where the non-negligible interactions between Te atoms across vdW gaps play a major role. The structural integrity of the distorted quadruple-layer slabs is sustained by short and strong covalent bonds, and the key ingredient to keep the high in-plane anisotropy is the robust horizontal homopolar Ga–Ga bonds. In severely deformed samples, amorphization and the formation of micro-cracks help release the internal stresses.
