Instead of a nanocomposite structure consisting of randomly oriented nanocrystalline (nc-) grains < 10 nm surround by an amorphous (a-) matrix, as usually found for these systems, this Ti-Si-C-N coating shows much larger Ti(C,N)-grains with a preferred (200) orientation identify by X-ray diffraction analysis. The strong texturing and grain sizes > 10 nm of the coating are confirmed by high-resolution transmission electron microscopy images. The coating's hardness is 46.3 GPa, making it equally hard to, e.g., nanocomposite Ti-Si-N coatings. These hardness values can only be achieved by a strong interface between a-matrix and nc-grains and small grain size. Despite 41.1 at.% carbon content, no significant quantity of a-C is found, as evidenced by Raman spectroscopy analysis. In order to investigate the oxidation behavior of the coatings, X-ray diffraction experiments are carried out at room temperature and in-situ in ambient atmosphere at elevated temperatures. The room temperature measurement shows a strong texturing of the Ti(C,N) lattice and yielded additional information on an anisotropic grain size.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400644","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multifunctional phase-selective organogel (tert-butyl (S)-(5-amino-1,5-dioxo-1-(tetradecylamino)pentan-2-yl)carbamate, TBTC) is developed to remove oils and dyes from water. Benefiting from the significant van der Waals interaction between the long alkyl chain of TBTC and the oil, TBTC can rapidly disperse into the oil phase. Then, TBTC aggregates into fibers and solidifies oil through a repairable, dynamic, and balanced hydrogen bonding network, which can solidify and recover the spilled oil at room temperature. TBTC can also efficiently remove more than a dozen typical dye contaminants through a host–guest recognition mode. The mechanism of host–guest recognition is studied by experiment combined with multiscale calculations. Partial 1H VT NMR, FTIR, and XRD experiments have shown that the main driving force for TBTC gelation and host–guest recognition originates from interaction hydrogen bonding, are TBTC specifically recognizes dye molecules through weak hydrogen bonding interactions and rapidly aggregates to form precipitates. TBTC-based organogel provides a potential solution for oil spill recovery and removal of dyes from water.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 3","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400525","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, the EU banned certain single-use plastic items in 2021—but food packaging is not part of this new regulation. And indeed, the majority of food packaging encountered today in the supermarket is still made from traditional, petrol-based plastics. This review summarizes recent efforts in developing more sustainable alternatives to such petrol-based food packaging. Different natural sources and production processes used to develop biodegradable, biopolymer-based materials (bbMs) are discussed, which are categorized into natural bbMs, modified/plasticized bbMs, and plastic bbMs. An overview of the material properties of commercially available bbMs and bbMs developed in academic research projects is provided, and are compared with the properties of conventional, petrol-based materials used for packaging. Furthermore, the role of academic and industrial contributors along the value chain of bbMs is highlighted and challenges that are responsible for the still limited occurrence of bbMs in daily lives are discussed.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 6","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400645","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A commercial AF3-HWK9-75-X membrane from Ionomr Innovations Inc. is characterized and employed in a 25 cm2 electrolyzer cell, which is operated for 56 h at 60 °C in 1 M KOH solution. A model of the membrane is developed, based on a combination of existing theoretical knowledge regarding liquid electrolytes and measured properties of the membrane. The model is employed to quantify the transport parameters through the membrane and the porous electrode. The hydrogen transport through the membrane is 770 times slower than through the electrode. The anion-exchange membrane permits a low degree of gas crossover, with a hydrogen-in-oxygen concentration of <math>\u0000 <semantics>\u0000 <mrow>\u0000 <mn>0.37</mn>\u0000 <mspace></mspace>\u0000 <mo>%</mo>\u0000 </mrow>\u0000 <annotation>$0.37,%$</annotation>\u0000 </semantics></math> at 2 Acm−2. The model indicates that modifying the membrane's microstructure has a more pronounced effect on the gas crossover than altering the swollen thickness.

However, there is a prevailing notion that physisorbed protein layers lack structural order, thus potentially compromising their stability and sensitivity compared to antibody films that are covalently attached to the substrate surface. This study demonstrates the preferential orientation of β-sheets within the secondary structure of protein layers, specifically anti-immunoglobulin G (anti-IgG) and bovine serum albumin (BSA), when physisorbed onto gold (Au) thin films. Using polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS) and infrared attenuated total reflection (IR-ATR) spectroscopy, it has been confirmed that the β-strands in these protein layers are tilted relative to the surface normal by average angles of 75.3° ± 0.4° for anti-IgG and of 79.3 ± 0.2° for BSA. These results are obtained by analyzing the orientation of the transition dipole moments (TDMs) associated with the amide I molecular vibrations derived from a comparison between experimental and simulated mid-infrared spectra assuming isotropically oriented TDMs. The simulations incorporate refractive and absorption index dispersions obtained from the IR-ATR spectra. Thus obtained findings offer valuable molecular-level insights facilitating the design and optimization of biofunctionalized interfaces in advanced biomedical and biosensing applications.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 6","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400867","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, this work designs and successfully prepares a nontoxic, environmentally friendly organic activator on the surface of carbon materials through in situ organic fermentation treatment method. The production of activated carbon via this novel organic activator is at a temperature of 850 °C under CO2 atmosphere for an activation time of 90 min, showing a specific surface area (SBET) of 1354 m2 g−1, an adsorption capacity of iodine (QI) of 1195 mg g−1, and a total pore volume (Vtot) of 0.855 cm3 g−1. Compared to the activated carbon prepared at high temperature under pure CO2, these results represent increases of 69.67%, 53.01%, and 93.44% in SBET, QI, and Vtot values, respectively. By means of thermogravimetric (TG) analysis and simultaneous thermal analysis-Fourier transform infrared spectroscopy-gas chromatography/mass spectrometry a suggested activation process and mechanism of the novel organic activators is proposed. This organic activator is not only used for semi-coke (SC) based activated carbon preparation and saturated activated carbon (SAC) regeneration, but also attracts other industrial activated carbon production.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 3","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400450","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
