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}

For screening biphasic reactions at high throughput, a platform based on microfluidic double emulsions can use widely available FACS (Fluorescence Activated Cell Sorting) machines to screen millions of picoliter reactors in a few hours. However, encapsulating biphasic reactions within double emulsions to form FACS-sortable droplet picoreactors requires optimized solvent phases and surfactants to produce triple emulsion droplets that are stable over multi-hour assays and compatible with desired reaction conditions. This work demonstrates such FACS-sortable triple emulsion picoreactors with a fluorocarbon shell and biphasic octanol-in-water core. First, surfactants are screened to stabilize octanol-in-water emulsions for the picoreactor core. With these optimized conditions, stable triple emulsion picoreactors (>70% of droplets survived to 24 hr), produced protein in the biphasic core via cell-free protein synthesis are generated, and sorted these triple emulsions based on fluorescence using a commercial FACS sorter at >100 Hz with 75–80% of droplets recovered. Finally, an in-droplet lipase assay with a fluorogenic resorufin substrate that partitions into octanol is demonstrated. These triple emulsion picoreactors have the potential for future screening bead-encoded catalyst libraries, including enzymes such as lipases for biofuel production.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 3","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111853","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}

Polyelectrolyte multilayers (PEMs) incorporating metal/metal oxide nanoparticles (NPs) as antimicrobial components receive special attention for their ability to coat diverse surface types and low potential to induce antimicrobial resistance. This study investigates the potential of poly(amino acid) multilayers consisting of poly-L-lysine and poly-L-glutamic acid with embedded silver (PEMAg) or copper oxide (PEMCuO) deposited on titanium surfaces for the coating of medical surfaces. The results of the quartz crystal microbalance with dissipation, scanning electron microscopy, and electron dispersive spectroscopy show that both types of NPs are successfully incorporated in the PEM and deposited over the entire coated surface. The incorporation of NPs in PEM prevents the burst release. The viability of MG-63 cells is higher than 70% on all investigated PEMs, confirming their biocompatibility. PEMCuO shows better biofilm prevention compared to PEMAg, entirely preventing Pseudomonas aeruginosa biofilm and allowing the formation of only weak Staphylococcus aureus biofilm. The results obtained confirm the high potential of poly(amino acids) multilayers with embedded metal/metal oxide NPs as biocompatible antimicrobial coatings for medical devices.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400631","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497084","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}

The influence of local changes in pressure and temperature due to different reactor configurations on the structure and quality of hBN films grown on Ge(001)/Si is studied. Injection of the borazine precursor close to the sample surface results in an inhomogeneous film thickness, attributed to an inhomogeneous pressure distribution at the surface, as shown by computational fluid dynamics simulations. The additional formation of nanocrystalline islands is attributed to unfavorable gas phase reactions due to the radiative heating of the injector. Both issues are mitigated by increasing the injector-sample distance, leading to an 86% reduction in pressure variability on the sample surface and a 200 °C reduction in precursor temperature. The resulting hBN films exhibit no nanocrystalline islands, improved thickness homogeneity, and high crystalline quality (Raman FWHM = 23 cm−1). This is competitive with hBN films grown on other non-metal substrates but achieved at lower temperature and with a low thickness of only a few nanometers.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400467","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120308","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}

Indeed, the problem of hydrocarbon contamination is known from the earliest days of electron microscopy and efforts to reduce this problem are ubiquitous to almost all high-vacuum experiments. Accurate knowledge of the behavior of such contamination is essential for electron beam (e-beam) based atomic fabrication, where it is aspired to select and control matter on an atom-by-atom basis. Here, the vexing question of hydrocarbon contamination on graphene is taken up. Image intensity is used to directly reveal the presence of diffusing hydrocarbons on ostensibly clean graphene. These diffusing hydrocarbons are previously inferred but not directly observed. Surprising dynamic variations of the concentration of these hydrocarbons impels questions about their origin. Here, some possible explanations are presented and some tentative conclusions are drawn. This work updates the conceptual model of “clean graphene” and offers refinements to the description of e-beam induced hydrocarbon deposition.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400598","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119710","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}

To verify the layer numbers of the multi-layer MoS2 films, atomic layer etchings are adopted. Wafer-scale MoS2 film growth with good layer number uniformity up to 30 is observed. A vertical device with 20-layer MoS2 embedded in between Al (bottom) and Au (top) electrodes is fabricated. With different work functions of the metal electrodes, photo-excited electrons and holes in the MoS2 layer can be separated and form photovoltaic responses. With the insertion of 5 nm MoO3 carrier transport layer between the MoS2 layer and the top Au electrode, enhanced photovoltaic responses are observed for the device. By using graphene as the carrier transport layer and MoS2 as the light absorption layer, avalanche photocurrents are observed for planar MoS2/graphene photoconductive devices. With the assist of the higher electron density in multi-layer MoS2, an easier compensation in the loss of photo-excited electrons and therefore, charge neutrality in the MoS2 layer can be maintained. Significant reduction in the rise/fall times from >100 ms. to <10 ms. is also observed for the planar photodetector with 10-layer MoS2 absorption layer.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400641","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497411","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}
