This work is the first demonstration of the discovery and quantification of interferon‐inducible protein (IP‐10) and tumor necrosis factor‐related apoptosis‐inducing ligand (TRAIL), two key prognostic markers of infection in human sweat. The levels of IP‐10 and TRAIL in sweat are quantified, validated, and confirmed using a standard reference method through preclinical human subject studies. Additionally, simultaneous and continuous detection of IP‐10, TRAIL, and C‐reactive protein (CRP), for infection monitoring in sweat using a wearable SWEATSENSER device is demonstrated. The SWEATSENSER is ultrasensitive with a limit of detection of 1 pg mL−1 (IP‐10 and TRAIL), 0.2 ng mL−1 (CRP) with a wide dynamic range. Bland–Altman analysis demonstrates good agreement between SWEATSENSER and standard reference methods through human subject studies. Serum to sweat relationship demonstrates the potential of the SWEATSENSER to track infection etiology.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88972920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a micro‐TEG (μTEG) with chip‐level size, rapid response, and high and stable responsivity is desired for real‐time and full‐time respiration monitoring to predict and diagnose breath‐related diseases. In this study, a thin‐film compact μTEG is elaborately designed by combining an ultrathin vertical structure for rapid heat conduction and a horizontal high‐integration density for transient response and a high filling rate. The device integrated with 28‐pair micro thermoelectric (TE) legs is fabricated on an aluminum nitride (AlN) substrate, which is patterned using ultrafast laser direct writing with embedded bottom contacts and TE legs. This unique design of the proposed μTEG provides a rapid response of 8 ms and chip‐level size of 1.9 mm × 2.7 mm × 400 μm for easy wearability. Additionally, application scenarios of real‐time respiration monitoring are demonstrated by mounting the μTEG under the nostril and near the mouth. The recorded airflow signals are displayed precisely with distinct features separating the nose and mouth breathing. Thus, the study presents a subtle and wearable respiration sensor for real‐time and full‐time human physiological signal acquisition.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82346265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In line with this demand, a techno‐economic evaluation of aluminum as a cross‐sectoral renewable energy carrier is conducted. The assessment, based on a newly developed process, involves the wet combustion of Aluminum at 700 °C resulting in heat and hydrogen (H2) generation. The designed conversion plant enables the contemporaneous generation of electricity and on demand H2 (up to 4 MW and 46.8 kg h–1) with round‐trip efficiencies as high as 40.7% and full recycling of the Al2O3 waste. This study, assuming the carbon‐free production of Al and three different energy cost scenarios, proves the feasibility of the e‐fueling station business case. The overall energy conversion including fuel production (power‐to‐Al), utilization (Al‐to‐power and Al‐to‐H2), and recycling requires a capital investment of 5200 € per kW installed power without additional primary material demand. Hence, the estimated power‐to‐X cost for the Al‐based H2 is estimated in the range of 4.2–9.6 € kg–1 H2, while wind and solar power based green H2 production cost varies from 6.5 to 12.1 € kg–1 H2.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81844875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still a big challenge to obtain good EMI shielding in transparent and/or curved surfaces. In this paper, a light, ultrathin, transparent, and flexible EMI shielding film based on woven silver nanowire (Ag‐NW) 3D networks is successfully prepared via a room‐temperature template production method. For transparent application scenario, Ag‐NWs with 91% transmittance in visible range show ≈27 dB shielding efficiency. This sample shows ≈27 dB shielding efficiency, although with a low density of Ag‐NWs (≈0.0168 mg cm−2), which implies that this material has a cost‐effectiveness. Moreover, total shielding as high as ≈40 dB is obtained by using thickened Ag‐NW grids. The EMI has not changed remarkedly after bended 1200 times, which indicates the as‐prepared flexible film has a relative stability of the EMI performance. Considering the facile production technology, this material can be readily applied in transparent EMI shielding.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73100927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Powering skin‐interfaced electronics requires thin and lightweight energy storage devices, where solution‐processing enables scalable fabrication. To attain such devices, a sequential deposition is employed to achieve all spray‐coated symmetric microsupercapacitors (μSCs) on ultrathin parylene C substrates, where both electrode and gel electrolyte are based on the cheap and abundant biopolymer, cellulose. The optimized spraying procedure allows an overall device thickness of ≈11 µm to be obtained with a 40% active material volume fraction and a resulting volumetric capacitance of 7 F cm−3. Long‐term operation capability (90% of capacitance retention after 104 cycles) and mechanical robustness are achieved (1000 cycles, capacitance retention of 98%) under extreme bending (rolling) conditions. Finite element analysis is utilized to simulate stresses and strains in real‐sized μSCs under different bending conditions. Moreover, an organic electrochromic display is printed and powered with two serially connected μ‐SCs as an example of a wearable, skin‐integrated, fully organic electronic application.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78385385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Razmjou, Matthias Wessling, Vicki Chen","doi":"10.1002/admt.202100930","DOIUrl":"https://doi.org/10.1002/admt.202100930","url":null,"abstract":"DOI: 10.1002/admt.202100930 filters, revealed that a boost in ion selectivity can be achieved by engineering the ionic topology into an ionic nanochannel by adding an asymmetric element into both “chemistry” and “morphology” of the membranes.[1,2] This can be achieved by building an asymmetrical factor in membrane building blocks or during assembly. There is a need for research on how to assemble at scale ion-selective nanochannels into defect-free membrane-like morphologies with high packing density and long-term stability. Achieving this technological development will allow conversion to viable materials manufacturing and novel ion sensing systems or extraction processes. Our current understanding of ion transport based on electric double-layer overlapping, the dehydration of ions, ionic affinity difference, one-surface-charge-governed ion transport and higher mobility of target ions within nanochannels and membranes are not sufficient to explain new findings. Recent reports[3] identified that other contributory factors must be considered during ISM design such as Zig-Zag transport (twosurface-charge-governed transport because of spontaneous symmetry breaking of charge), different ionic velocity gradient (acceleration and deceleration behaviour of ions as a function of nanochannel dimensions, functional groups and asymmetry in morphology and chemistry), the effect of ice-like arrangements of water molecules on ion selectivity within the asymmetric nanoconfined areas, hydrated ion trapping phenomena, internal concentration polarization and accumulation of ions, orbital involvements of atoms of the nanoconfined areas, and gradual dehydration of ions within the asymmetric nanoconfined areas. The special section of ion-selective membranes covers both fundamental and practical topics that reflect the growing importance of the field over the years. To begin, Amiri et al. (2001308) reviewed recent reports on the design and development of ISMs to control proton transport within Vanadium Redox Flow Batteries (VRFB). A variety of modification strategies were reviewed and an attempt was made to introduce a design platform for future work. Jovanović et al. (2001136) reviewed recent advances in the performance of separators in Li–S batteries and proposed guidelines for measurements with respect to key properties. Ion-exchange membranes (IEMs) are categorized as one of the traditional types of ISMs. Shehzad et al. (2001171) reviewed systematically four types IEMs: self-assembled nanochannels, solid-state nanostructures, artificial surface structures, and fillers-integrated nanostructures. Although mixed matrix membranes have been extensively used for gas separation and water purification, their application for ion separation is yet to be fully explored.
