However, the weak hydrostability of ZIF-67, due to structural hydrolysis and degradation, dramatically limits their applicability after aqueous exposure. In this work, cosolvent-stabilized superhydrophobic, highly hydrostable ZIF-67 was synthesized at room temperature using a facile, one-pot hydrothermal synthesis route, and the effect of cosolvent concentration on ZIF-67 crystal structure properties and hydrostability was studied systematically. The underlying mechanism for the cosolvent-supported hydrostability improvement was also proposed. Furthermore, the influence of hydrotreatment on the resultant ZIF-67s' catalytic performance was studied in the ‘Sabatier reaction’ for CO2 to synthetic natural gas (CH4) conversion. The ZIF-67-derived calcined catalysts obtained from the hydrotreated samples of the cosolvent-stabilized ZIF-67 exhibited no prominent loss in catalytic performance and showed better CO2 conversion, higher CH4 selectivity, and less CO production, in comparison to the conventional ZIF-67 samples. Notably, the use of a lower ligand-to-metal ratio (∼8) in the current synthesis significantly reduced the overall chemical consumption, achieving highly economically and environmentally friendly manufacturing of exceptionally hydrostable ZIF-67.","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"39 5","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513145","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}

Here, a poly(lactic-co-glycolic acid) (PLGA)/magnesium hydroxide (MH)/vitamin D (Vit D) microsphere-incorporated α-calcium sulfate hemihydrate (α-CSH)/beta-tricalcium phosphate (β-TCP) injectable paste was designed for the regeneration of bone tissue. The combination of the bioceramic particles with α-CSH demonstrated an appropriate setting time for ease of use in clinical practice and enhanced mechanical properties. Additionally, the introduction of a bone paste with the MH and Vit D-incorporated PLGA microsphere induced osteogenic differentiation and alleviated the inflammatory response, which may occur after massive bone surgery. Based on these findings, this paper presents a versatile bone paste that promotes osteogenesis and modulates the osteoimmune microenvironment for effective bone regeneration.","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"40 4","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513137","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}

In addition to conventional internal fixation and auto- or allografts, multifunctional supportive treatments are needed for limb reconstruction after tumor removal. With inspiration from the \"organic-inorganic\" hybrid concept, we developed a freestanding polyelectrolyte membrane (PEM) using a layer-by-layer (LBL) deposition of quaternized chitosan (QCS) and hyaluronic acid (HA), and with copper-doped laponite (CuLAP) intercalation. The CuLAP demonstrated photothermal conversion capabilities under near-infrared (NIR) light irradiation, and displayed glutathione (GSH)-depleted Fenton-like catalytic activity. The further engineered PEM possesses a \"brick and mortar\" structure with enhanced surface roughness and stiffness. The fusion of CuLAP-mediated GSH-depleted chemodynamic treatment (CDT) and moderate photothermal therapy (PTT) facilitated tumor ablation and bactericidal effects. Moreover, the continuous release of copper ions and silicates aided angiogenesis and osteogenesis, supporting the regeneration of both soft (skin) and hard (bone) tissues. This all-in-one platform offers a promising clinical tool for assisting tissue reconstruction after osteosarcoma resection.","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"39 11","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513143","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}

Heat treatments on the alloy resulted in the formation of second phases and thus were able to adjust its transformation temperatures. This phenomenon results from the formation of H-phase and (Zr,Hf)7Cu10 phase during low-temperature and high-temperature aging, respectively. The superelasticity of solution-treated, 500 °C-aged and 700 °C-aged samples was tested under compression, and all samples exhibited nearly 5 % recoverable strain and 15 °C elastocaloric cooling capacity. Further cyclic compression tests confirmed their stability, with up to 75 % of the initial cooling capacity retained after 5000 compression cycles. Due to its high yield strength, the Ti30Zr10Hf10Ni35Cu15 high-entropy shape memory alloy showed great superelasticity and elastocaloric performance at various testing temperatures. Furthermore, with heat treatments, the austenitic transformation finishing temperature (Af) of the alloy was tunable to between −10 °C (furnace-cooled) and 60 °C (700 °C-aged) with promising functional performance. These features expand the application range of TiZrHfNiCu high-entropy shape memory alloys as potential superelastic and elastocaloric materials.","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"39 2","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513147","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}

ENP is extraordinarily capable of generating intense nanopulse electric current with a current density greater than a few to several hundreds of 1010A/m2 and a pulse duration on the order of a few 100ns. Such a level of current density is ∼3–5 magnitudes higher than that is usually achieved during the Spark Plasma Sintering process. Using the Nichrome-80 superalloy as a model material, we observed a variety of GB roughening phenomena at multiple length scales, resulting in the generation of diverse forms of atomistic facets, nanoscale serrations, and nanoscale step-like GB morphologies after the ENP processing. We think that the excessive GB heat localization and electron wind force or stress are the main factors contributing to the GB morphological changes during the ENP processing. The ENP processing provides a new unique grain boundary engineering strategy to manipulate the GBs with the changes localized at the GB region, without altering its adjacent grains.","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"40 5","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513136","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}

The results showed that the average grain size is reduced by 74 % (from 278 μm to 72 μm), the average microhardness is increased by 41 % from 568 HV1 to 807 HV1, the abrasion resistance is improved by 68 % under the effect of ultrasonic impact. The ultrasonic impact treatment process can effectively refine the microstructure of the coatings and improve the strength of grain boundaries. The corrosion resistance of the coating in 3.5 wt% NaCl solution is enhanced by 65 %, the corrosion type was changed from intergranular corrosion to uniform corrosion. This is mainly caused by the ultrasonic impact treatment which suppresses the elemental segregation of Cr and Mn and improves the grain boundary strength.","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"88 8","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513162","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}
