Meanwhile, the development of magnetic MOFs with excellent adsorption capabilities and outstanding recyclability is crucial. Herein, a novel magnetic Fe/Ni bimetal MOFs composite (MIL-101(Fe)@NiFeO, MNFO) for LVX capture has been effectively fabricated for LVX capture, utilizing MIL-101(Fe) as the primary adsorbent and NiFeO nanoparticles as the magnetic element. Attributed to the synergistic ability of bimetal ions (Fe and Ni), MNFO exhibits a significant adsorption capacity (335 mg/g) and rapid adsorption rate (10 min) towards LVX. The adsorption capacity indicates an increasing-then-decreasing trend with an increase of the pH values. Additionally, the adsorption data are well fitted by the Freundlich and pseudo-second-order kinetic models. Thermodynamic studies indicated that the adsorption process was spontaneous and endothermic. In addition, the adsorbent demonstrated excellent reusability, as it could be readily recovered from the liquid phase through the magnetic properties of NiFeO. Remarkably, it retained approximately 90 % of its adsorption capacity of the uptakes after 5 cycles. This study offers a innovative approach to the development of highly efficient adsorbents for capturing LVX from water.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collagen, known for its biodegradability and biocompatibility, holds promise for wound healing. However, challenges such as poor mechanical properties, stability, and the lack of antibacterial properties when using collagen alone have led to the development of various solutions. The review discusses different types of collagen-based dressings, their preparation methods, and how their internal structure influences their ability to accelerate the healing of different wound types. Additionally, the article emphasizes the significant potential for the application of collagen dressings in future skin tissue engineering and in vivo tissue engineering. Specifically, three-dimensional scaffolds prepared from nanofibers through electrospinning show promise for more efficient collagen-based wound dressings, as these nanofibers have a similar extracellular matrix structure and high specific surface area, which can stimulate tissue hemostasis and promote cell adhesion, proliferation, and differentiation. However, challenges such as high production costs and poor stability in the commercial production of nanofibers need to be addressed. Overall, collagen dressings hold great promise for future applications and can play a significant role in skin tissue engineering and even in vivo tissue engineering.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein we create a lead-free double metal perovskite of CsAgBiBr, coupling with mesoporous/microporous UiO-66-NH MOF to form type-II heterojunctions for efficient photocatalytic reduction of CO with a high CO selectivity of 95 % at an electron consumption rate of 33 μmol g h (13.4 μmol g h for CO and 0.72 μmol g h for CH). Multilayered mesoporous MOF particles manifest higher catalytic activity than their microporous counterparts due to the highly open mesoporous channels and larger pore volume of the former. Femtosecond transient absorption in combination with in situ infrared spectroscopic measurements disentangle the underlying mechanism accounting for the high product selectivity: the ultrafast electron transfer of 12.3 ps from CsAgBiBr to UiO-66-NH-2 enables efficient charge separation; primary *COOH intermediates and rapid CO desorption from Bi-based photocatalyst lead to dominant CO product. Moreover, the MOF crystals maintain stability after γ-rays irradiation equivalent of over 45-year accumulation in a typical earth orbit, hinting their promising potential in extraterrestrial artificial light synthesis.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, MgTiO:Mn (MTO:Mn) novel red-emitting phosphors are synthesized through a solvothermal method, which demonstrates a promising approach for enhancing latent fingerprint detection capabilities and improving the performance of red LEDs. The confirmation of the cubic structure post-annealing and the nano-nature as revealed by TEM analysis underpin the MTO:Mn phosphors suitability for these applications. The broad excitation spectra and the sharp red emission at 659 nm, coupled with the optimal doping concentration, showcase the MTO:Mn phosphor's efficient luminescence properties. Moreover, the calculated critical distance between Mn ions (32.906 Å) elucidates the concentration quenching mechanism, which is pivotal for optimizing the performance. The high purity of the emitted red light (97.2 %) and the precise CIE coordinates (0.5969, 0.2926) of the MTO:Mn phosphor suggest its potential for producing high-quality red LEDs. Additionally, the capability of MTO:Mn phosphors to reveal detailed and high-resolution latent fingerprints offers a more reliable and efficient method for processing and analyzing crucial evidence. These findings not only contribute to the scientific understanding of MTO:Mn phosphor materials but also pave the way for their practical application in cutting-edge technologies.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pretreatments in either pure hydrogen or dry reforming CO/CH mixtures exclusively yield partial decomposition of the initial double perovskite structures through exsolution of small Ni or CoO particles and the associated formation of additional crystalline compounds, such as SrMoO or SrCO (in DRM mixtures). The formation of a defective SrMoO transient phase has been revealed by in situ X-ray diffraction measurements in a pure hydrogen atmosphere. The main difference between the Ni- and Co-containing Sr molybdate perovskite structures is the much stronger oxidation propensity of exsolved Co, most likely by oxygen supply from the partially intact double perovskite structure. For SrNiMoO, the resulting metallic Ni-double perovskite interface is highly DRM active without strong coking, both if a pre-reduction step in hydrogen is carried out before the DRM experiment or if SrNiMoO is directly decomposed in the DRM mixture. Despite partial decomposition, the corresponding SrCoMoO structure is not active under DRM operation, most likely due to the in situ formation of small exsolved CoO particles, while Ni is exsolved in its metallic state. Different strategies to improve the catalytic activity, including hydrogen by-mixing, enhanced A-site deficiency or co-alloying with Ni have been followed, but only the latter has a beneficial effect on improving the DRM activity at compositions of SrNiCoMoO. In SrNiCoMoO, the substitution of Co by Ni suppresses the oxidation propensity of Co and during DRM yields the exsolution of Co-rich Ni–Co alloy nanoparticles. We also reveal a strong response of molybdenum as the B’ site cation to reduction and DRM treatment, causing the formation of reduced MoO phases accompanying the exsolution process.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, current ceramic elaborations involves strict and complex synthetic procedures such as ultra-high pressure and vacuum processing. Here, we realize the tune of MgAlSiO and MgAlSiO phase formation in a glass by controlling the two crystal nucleation and growth individually, and obtain a polycrystalline non-stoichiometric MgAlSiO:Eu translucent ceramic by virtue of complete and congruent crystallization of the glass. Microstructural characterizations verify that the resulting ceramic exhibits dense and closely stacked micrometer-scale crystallites with very thin grain boundary structure. Chemical composition analysis by energy dispersive X-ray spectrometry revels the grain's composition is highly deviated from the stoichiometric MgAlSiO, with atomic ratio Mg/Al/Si of 1.00: 1.46: 2.70. The precipitated non-stoichiometric MgAlSiO, structurally having infinite channels z = 0.25 or 0.75 sites that run parallel to the -aix, provides an robust crystal-field environment for Eu 5d-4f transition. As a consequence, the ceramic produces intense emission with photoluminescence quantum yield (PLQY) up to 90 %, and excellent thermal stability emission with 70.1 % emission intensity at 420 K relative to that at room temperature, demonstrating it can be applied in high power lighting application with improved light quality by employing the ceramic as a color converter. Moreover, the ceramic also exhibits thermally stimulated luminescence at temperature reaching up to 700 K, originating from the deep electronic traps in MgAlSiO lattice with estimated trap depth of 0.73eV and 0.97eV. We also demonstrate the ceramic is hopeful for optical information storage application as the storage information can be retain well without vulnerable by the fluctuations of external environments due to the deep traps.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce highly flexible, self-rotating nanorobots based on MoS Nanoflowers (NFs), offering superior control over their movement under magnetic field for cancer cell imaging and therapy. These nanorobots, termed MNBOTs, are constructed by embellishing pre-formed MoS NFs with NiFeO nanoparticles (NPs) using polymeric linkers, capitalizing on the abundance of disulfide bonds on the MoS surface. In-vitro experiments showcased MNBOT's precise control over velocity, trajectory, and curvature, adapting seamlessly to changes in magnetic flux density under electromagnetic navigation. Moreover, MNBOTs were able to release NiFeO NPs successfully in the tumor environment, facilitated by the collapse of disulfide bonds in the presence of glutathione/dithiothreitol, thus ensuring MNBOT's retrieval post-cancer therapy. Furthermore, we leveraged the photo-heat generation and paramagnetic features of MNBOTs for chemo-photothermal therapy (PTT) and magnetic resonance imaging (MRI) in ex vivo clinical settings. The combined effect of chemotherapy-PTT demonstrated remarkable cytotoxicity against MDA-MB-231 cancer cells, highlighting the synergistic potential of MNBOTs. The integration of diverse functionalities within MNBOTs, including remote magnetic navigation, photothermal therapy, and MRI, presents a versatile platform for addressing pressing healthcare needs, thus holding immense potential for future therapeutic and diagnostic applications.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
