However, synthesizing multicomponent high-entropy oxides (HEOs) consisting of over ten metal cations remains a challenge due to dissimilarity and immiscibility among these elements. Herein, we explore the accommodation ability of AlNi-type and AlTi-type intermetallic phases and find that the AlNi-type phase is powerful to accommodate many different kinds metal elements. By chemically dealloying the Al from the multicomponent AlNi-type intermetallic phase, multicomponent spinel oxides such as 7-component (AlNiCoRuMoCrFe)O, 8-component (AlNiCoRuMoCrFeTi)O, 13-component (AlNiCoCrFeCuMoVTaNbHfZrTi)O, 16-component (AlNiCoCrFeCuMoTaNbHfZrTiRuVPdY)O et al., with nanoporous structure and poor crystallity are obtained. As a case study, we find that when applied in Li-ion battery anode, our 16-component nanoporous HEO exhibits a high capacity of ∼1141.2 mAh g after 290 cycles at 0.1 A g and excellent cycling stability. This study greatly expands the composition space of nanoscale HEOs and provides an interesting route for new materials discovery.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141880604","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}

However, most conductive hydrogels would reduce the sensitivity and accuracy of hydrogel-based strain sensor for the lack of self-adhesion. Herein, a highly stretchable and excellent adhesive hydrogel based on chitosan network and ionic liquid crosslinking network was prepared. Chitosan (CS) worked as network skeleton, which could enhance the mechanical properties of hydrogel by participating in the construction of double network structure. Furthermore, dimethylaminoethyl methacrylate maleate (DM-M) as cross-linker, the hydrogel was imparted with high ionic conductivity (0.29 S/m) while it also enhanced the mechanical properties of the hydrogel. The ionic bonding conferred high toughness to the hydrogel for avoiding stress concentration during tensile process. Additionally, the hydrogel could form strong adhesion to a variety of substrate surfaces through electrostatic interaction, hydrogen bond and metal complexation. Meanwhile, the hydrogel remained strong adhesion under different pH, solvent and temperature condition. Therefore, the hydrogel with excellent adhesive property, mechanical properties and high electrical conductivity have been designed as flexible strain sensor, which could detect limb movement and physiological signals with real-time feedback electrical signals. Thus, this highly stretchable, tough and adhesive hydrogel based on double network structure would promote the development of flexible electronic device.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141880608","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}

Among many methods for detecting HClO, photoelectric chemical sensor has the advantages of high sensitivity and strong anti-interference ability, and has been widely used in the field of detecting HClO. Herein, a simple and specific photoelectrochemical sensor was constructed using A1/B1-type pillar[5]arene functionalized Au NPs and multi-walled carbon nanotube-polythiophene composites for the detection of hypochlorous acid. This approach was based on a sulfhydryl-borate ester modified A1/B1 type pillar[5]arene (BP5) as the main body, hypochlorous acid (HClO) as the guest, multi-walled carbon nanotube (MWNTs) conducting polymers doped with poly(3,4-ethylenedioxythiophene) (PEDOT) as the transport bridge and signal amplifier, as well as spherical gold nanoparticles act as the signal reporter. Specifically, the photoelectrochemical efficiency was further enhanced by the localized surface plasmon resonance effect (LSPR) of gold nanoparticles (Au NPs) and the host-guest complexation between BP5 and HClO. The large specific surface area of MWNTs doped with PEDOT significantly enhanced the electrical conductivity and chemical stability of PEDOT, facilitating accelerated electron transfer and mitigating the recombination of the photogenerated electron-hole pairs. Benefiting from the combination of Au NPs, BP5, MWNTs and PEDOT, the sensor exhibited excellent sensitivity with detection range of 0.5–340 μM and a detection limit of 0.17 μM, and distinguished selectivity against 6 interfering substances. Due to the adsorption and removal effects of pillar[5]arenes on heavy metal ions and pollutants in water, as well as their effective catalytic performance, we anticipate that this composite material also has great potential in photoelectrochemical detection, catalysis, and adsorption.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141880611","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}

We accomplished this by employing a solution isopropanol (IPA), capable of selectively dissolving residual unreacted methylammonium and formamidine salts on the perovskite surface while preserving the integrity of lead iodide. Through control of the immersion time, we facilitated secondary crystal growth on the top of perovskite film. The resultant treated film exhibited a markedly suitable bandgap position and a diminished presence of residual trips. The IPA-treated sample led to a noteworthy photovoltaic conversion efficiency (PCE) of 23.34 %, compared to 21.46 % efficiency for untreated control sample. Furthermore, under sustained illumination at AM 1.5G with 25 % relative humidity, the uncovered IPA-treated sample retained an impressive 92 % of their initial efficiency after 1000 h. Further scrutiny revealed that this solution-based treatment effectively passivated trips, enhanced perovskite film quality, established novel built-in electric fields, and mitigated charge carrier recombination.

Carboxylic acids, the resulting products, are not only important chemical raw materials but also fundamental pharmaceutical intermediates. Zn-based catalysts have gained attention as a promising option for this transformation owing to their economic cost and abundant reserves. However, stability issues, including structure collapse and morphological changes, have plagued the reported Zn-based catalysts during this transformation. In response to these challenges, this study focused on the design and development of Zn-based catalysts via controlled incorporation of Zn into nitrogen-doped porous carbon to modulate the numbers of defects and Lewis acid-base site pairs. Through extensive screening of various parameters, the best-performing catalyst, namely Zn@NC-800, exhibited high activity and remarkable stability, surpassing all the reported Zn-based catalysts. Moreover, this catalyst demonstrated great recyclability since it could maintain approximately 90 % yields after 9 cycles. Notably, the product formation rate of this catalyst could reach 3833 μmol·g·h, exceeding that of most reported non-noble metal heterogeneous catalysts. Consequently, this study offers a promising approach for efficiently and stably catalyzing alcohol dehydrogenation reactions using non-noble metals.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141880536","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}

Traditional organic antifouling coatings often struggle with mechanical robustness in harsh marine environments, making them fragile and highly susceptible to abrasion. To address these challenges, we propose a novel “bifunctional domain engineering” strategy for designing robust antifouling coatings that combines excellent mechanical strength of a Fe-based amorphous layer and high antifouling efficacy of an incorporated organics. The hard domains consist of Fe-based amorphous micro humps, providing a sturdy framework that enhances the coating's mechanical durability. In contrast, the soft domains comprise epoxy resin infused with CuO and 4,5-Dichloro-2--octyl-4-isothiazolin-3-one (DCOIT), offering a dual-action antifouling function via controllable antifouling agent release. Evaluation of antifouling performance by lab tests against , , and algae and practical marine field tests (for 150 days) demonstrates significant reductions in bacterial and algal adhesion (nearly 100 % resistance) with the bifunctional domain engineered coating (referred to as HSR coating), compared to pure amorphous coating. Mechanical durability tests, including abrasion and erosion experiments, underscore the HSR coating's excellent wear resistance. Importantly, the HSR coating maintains its outstanding antifouling properties even after 1000 abrasion cycles, highlighting its potential for long-term marine applications in harsh conditions. This study lays the groundwork for design of robust antifouling coatings capable of withstanding the harsh operating environments while effectively combating biofouling.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141880613","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}

A novel P/N/S oligomer flame retardant (PALO) was synthesized of terephthalaldehyde (TPAL), 4-aminothiophenol (PATP), and 9, 10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO), and employed in EP to fabricate a series of EP/PALO composites with different PALO amount. Thermogravimetric analysis (TGA) revealed that PALO exhibited remarkable thermal stability, retaining a substantial char residue of 32.2 wt% at 800 °C. Thanks to the synergy of P, N, and S, EP/PALO composites exhibited excellent flame retardancy properties. The LOI value of the EP/PALO composites saw a rise from 31.0 % to 34.2 % as the PALO content increased from 2.5 to 10 wt%, while UL-94 remained at the V-0 rating. EP/PALO also showed significant heat suppression and smoke suppression effects. The combined effects of the physical barrier from phosphate-containing char in the condensed phase, along with the flame-retardant and dilution effects of phosphorus radicals, nitrogen, and sulfur inert gases in the gas phase, contributed to the significant enhancement in flame retardancy observed in the EP/PALO composites. A notable increase in the tensile strength, flexural strength, and elongation at break of EP was triggered by the incorporation of 2.5 wt% PALO, with enhancements observed by 18.2 %, 16.6 %, and 53.1 %, respectively. Simultaneously, PALO effectively maintained the favorable transparency of EP composites under different addition amounts. Therefore, this study outlined a holistic approach for the development of oligomer flame retardants containing P/N/S and had good application potential for constructing EP composites with superior flame retardancy, transparency, and mechanical properties under different addition amounts.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141775149","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}
