AbstractAnti‐counterfeiting and visual optical information encryption/decryption technology have attracted widespread attention in the field of information security. Luminescent encryption technologies still face a huge challenge in external high voltage power supply, complex architecture, and expensive decryption equipment, which hinder their broad applications. Herein, a wearable integrated self‐powered electroluminescent (EL) display device (W‐ELD) that consists of MXene/Silicone‐based triboelectric nanogenerator (MS‐TENG) and EL device based on a shared MXene electrode is developed for patterned display and information encryption. The W‐ELD features an all‐in‐one MXene electrode with excellent flexibility and high conductivity of 0.6 kΩ sq−1, which is shared by both MS‐TENG and EL devices. The MS‐TENG demonstrates excellent output performances (output power of 0.9 Wm−2) and high stability and durability (104 cycles), which can directly light up the flexible patterned EL device. More importantly, when dripping conductive electrolyte solution, the W‐ELD based on “中國”‐patterned MXene electrode can precisely reveal the encryption information through self‐powered EL emission for real‐time visualized information interaction. Consequently, the all‐in‐one MXene electrode‐based W‐ELD that integrates both MS‐TENG and EL device demonstrates exceptional patterned EL‐based information encryption features, which offers a potential prospect in wearable self‐powered optoelectronic devices, flexible displays, and encryption technology.

AbstractFlexible and skin‐mountable electronics have drawn tremendous research attention with the booming of smart medical systems and wearing technologies, however, their environmental adaptability to electromagnetic and solar radiation has long been neglected. Herein, a novel health monitoring e‐textile with robust ultraviolet (UV) protecting and strong electromagnetic interference (EMI) shielding performance is rationally developed on an ultraelastic and bilayered nonwoven textile. Via the respective incorporation of silver flake‐modified liquid metal (AgLM) and silver nanoparticles (AgNPs) on each side of a permeable substrate, a Janus sensing layer with electrophysiological monitoring function, Joule heating ability, and excellent EMI shielding capability (up to 38.5 dB in X band) is first fabricated. Elastic microfibers embedded with sensitive photochromic microcapsules are then in situ assembled on the bioelectric‐sensing layer, achieving a bilayered e‐textile with a reversible UV‐chromic property and an extraordinary UV protection factor (UPF) of 335.56. The developed all‐stretchable and UV‐EMI proof e‐textile is utilized as a safe and comfortable on‐skin electronic to provide point‐of‐care health regulation under complex UV/EMI radiative environments. Specifically, stable Joule heating performance and accurate monitoring of electrocardiogram (ECG) and surface electromyography (sEMG) are simultaneously obtained, demonstrating promising applications in multifunctional and robust wearing electronics.

Published: September 2023

AbstractRadiation‐induced colitis is a serious clinical problem worldwide. However, the current treatment options for this condition have limited efficacy and can cause side effects. To address this issue, colon‐targeted fullerenol@pectin@chitosan gel microspheres (FPCGMs) are developed, which can aggregate on colon tissue for a long time, scavenge free radicals generated in the process of radiation, and regulate intestinal flora to mitigate damage to colonic tissue. First, FPCGMs exhibit acid resistance and colon‐targeted release properties, which reduce gastrointestinal exposure and extend the local colonic drug residence time. Second, fullerenol, which has a superior scavenging ability and chemical stability, reduces oxidative stress in colonic epithelial cells. Based on this, it is found that FPCGMs significantly reduce inflammation in colonic tissue, mitigated damage to tight junctions of colonic epithelial cells, and significantly relieved radiation‐induced colitis in mice. Moreover, 16S ribosomal DNA (16S rDNA) sequencing results show that the composition of the intestinal flora is optimized after FPCGMs are utilized, indicating that the relative abundance of probiotics increases while harmful bacteria are inhibited. These findings suggest that it is a promising candidate for treating radiation‐induced colitis.

Published: September 2023

AbstractIn recent years, phase‐change materials have gained importance in nanophotonics and optoelectronics. Sizable optical contrast and added degree of freedom from phase switching drive the use of phase‐change materials in various optical devices with outstanding results and potential for real‐world applications. The local crystallization/amorphization of phase‐change materials and the corresponding reflectance tuning by the crystallized/amorphized region size have potential applications, for example, for future dynamic display devices. Although the resolution is much higher than in current display devices, the pixel sizes in those devices are limited by the locally switchable structure size. Here, the spot sizes are further reduced by using ion beams instead of laser beams, dramatically increasing pixel density, demonstrating superior resolution. In addition, the power to sputter away materials can be utilized in creating nanostructures with relative height differences and local contrast. The experiment focuses on one archetypal phase‐change material, Sb2Se3, prepared by pulsed‐laser deposition on a reflective gold substrate. This study demonstrates that structural colors can be produced and reflectance tuning can be achieved by focused ion beam milling/sputtering of phase‐change materials at the nanoscale. Furthermore, the local structuring of phase‐change materials by focused ion beam can produce high‐pixel‐density display devices with superior resolutions.
A Balance between Inter‐ and Intra‐Microgel Mechanics Governs Stem Cell Viability in Injectable Dynamic Granular Hydrogels

Published: September 2023

AbstractInjectable hydrogels are increasingly explored for the delivery of cells to tissue. These materials exhibit both liquid‐like properties, protecting cells from mechanical stress during injection, and solid‐like properties, providing a stable 3D engraftment niche. Many strategies for modulating injectable hydrogels tune liquid‐ and solid‐like material properties simultaneously, such that formulation changes designed to improve injectability can reduce stability at the delivery site. The ability to independently tune liquid‐ and solid‐like properties would greatly facilitate formulation development. Here, such a strategy is presented in which cells are ensconced in the pores between microscopic granular hyaluronic acid (HA) hydrogels (microgels), where elasticity is tuned with static covalent intra‐microgel crosslinks and flowability with mechanosensitive adamantane‐cyclodextrin (AC) inter‐microgel crosslinks. Using the same AC‐free microgels as a 3D printing support bath, the location of each cell is preserved as it exits the needle, allowing identification of the mechanism driving mechanical trauma‐induced cell death. The microgel AC concentration is varied to find the threshold from microgel yielding‐ to AC interaction‐dominated injectability, and this threshold is exploited to fabricate a microgel with better injection‐protecting performance. This delivery strategy, and the balance between intra‐ and inter‐microgel properties it reveals, may facilitate the development of new cell injection formulations.

AbstractLithium–sulfur (Li–S) batteries stand out for their high theoretical specific capacity and cost‐effectiveness. However, the practical implementation of Li–S batteries is hindered by issues such as the shuttle effect, tardy redox kinetics, and dendrite growth. Herein, an appealingly designed covalent organic framework (COF) with bi‐functional active sites of cyanide groups and polysulfide chains (COF‐CN‐S) is developed as cooperative functional promoters to simultaneously address dendrites and shuttle effect issues. Combining in situ techniques and theoretical calculations, it can be demonstrated that the unique chemical architecture of COF‐CN‐S is capable of performing the following functions: 1) The COF‐CN‐S delivers significantly enhanced Li+ transport capability due to abundant ion‐hopping sites (cyano‐groups); 2) it functions as a selective ion sieve by regulating the dynamic behavior of polysulfide anions and Li+, thus inhibiting shuttle effect and dendrite growth; 3) by acting as a redox mediator, the COF‐CN‐S can effectively control the electrochemical behavior of polysulfides and enhance their conversion kinetics. Based on the above advantages, the COF‐CN‐S endows Li–S batteries with excellent performance. This study highlights the significance of interface modification and offers novel insights into the rational design of organic materials in the Li–S realm.

AbstractThe integration of liposomes into hydrogels through direct soaking presents advantages such as facile formulation, enhanced drug stability, and controlled release kinetics. However, the feasibility of this approach is impeded by the difficulty of developing matching porous structures within hydrogels and achieving appropriate affinity with liposomes. To address these challenges, an alternative method is proposed for synthesizing macroporous hydrogels using thiolated hyaluronic acid and hyperbranched polyethylene glycol macromonomers in combination with a freezing‐induced secondary crosslinking process. This approach allows the locking of macropores formed by ice crystals during freezing and enables easy modification of the hydrogels with cholesterol groups to promote liposome association. Furthermore, these macroporous hydrogels can be crushed into granular hydrogels, which offer numerous benefits such as high loading capacity, injectability, self‐healing properties, and convenience in storage, dosing, and administration. Therefore, a liposome‐in‐hydrogel system can be formulated without any gelation or pre‐treatment, providing valuable insights for the further development of liposome‐based formulations for medical and cosmetic applications.

Published: September 2023

AbstractUV nonlinear optical materials require the simultaneous achievement of a large second harmonic generation (SHG) coefficient (≥1 × KH2PO4 (KDP), dij > 0.39 pmV−1), wide bandgap (λ < 300 nm, Eg > 4.2 eV), and moderate birefringence (0.05‐0.10@1064 nm) in a single structure. Therefore, designing UV nonlinear optical materials with excellent comprehensive performance is a challenging task. Herein, four UV transparent selenite materials are successfully obtained, namely, Al2(SeO3)3(H2O)3 (1), Ga2(SeO3)3(H2O)3 (2), NaGa3(HSeO3)6(SeO3)2 (3), and Cd5Ga4(HSeO3)2(SeO3)10 (4), through rational design and screening in the pure selenite system. Al2(SeO3)3(H2O)3 (1) and Ga2(SeO3)3(H2O)3 (2) are UV nonlinear optical materials with balanced properties, exhibiting moderate SHG responses (1.2 and 1.1 × KDP), appropriate birefringence (0.084 and 0.076@1064 nm), and wide bandgaps (5.5 and 5.3 eV). Such bandgaps are the largest in the reported pure selenite nonlinear optical (NLO) materials. This work further demonstrates that pure selenite is a good candidate for UV NLO materials.

Published: September 2023

AbstractLarge‐sized transparent scintillators with a high photoluminescent quantum yield (PLQY) and self‐absorption‐free properties are highly desired to achieve high spatial resolution X‐ray imaging. In this research, a transparent 0D organic–inorganic (ETP)2SbCl5 (ETP = Ethyl triphenylphosphine) amorphous wafer is developed by melting the ETPCl and SbCl3 mixture and then undergoing a quenching process. The obtained amorphous wafer exhibits a high light transmittance of 86% in the range of 450–800 nm. It also shows a light emission peak at 624 nm, a Stokes shift of 259 nm, and PLQY approaching unity (99.3%). These properties enable it to produce X‐ray images with a high spatial resolution of 19.0 lp mm−1 at a modulation transfer function (MTF) value of 0.2, among the best values reported. Additionally, it also shows remarkable stability under continuous X‐ray illumination. Its unique optical properties and ability to be processed in large sizes make the organic–inorganic metal halide transparent wafer a promising scintillator. This also demonstrates the potential application of the melt‐quenching method in fabricating highly luminescent, low‐electronic‐dimensional metal halide wafers.

AbstractTwo newly designed and synthesized [3+2+1] iridium complexes through introducing bulky trimethylsiliyl (TMS) groups are doped with a terminal emitter of v–DABNA to form an coincident overlapping spectra between the emission of these two phosphors and the absorption of v–DABNA, creating cascade resonant energy transfer for efficient triplet harvesting. To boost the color quality and efficiency, the fabricated hyper‐OLEDs have been optimized to achieve a high external quantum efficiency of 31.06%, which has been among the highest efficiency results reported for phosphor sensitized saturated‐blue hyper‐OLEDs, and pure blue emission peak at 467 nm with the full width at half maxima (FWHM) as narrow as 18 nm and the CIEy values down to 0.097, satisfying the National Institute of Standards and Technology (NIST) requirement for saturated blue OLEDs display. Surprisingly, such hyper‐OLEDs have obtained the converted lifetime (LT50) up to 4552 h at the brightness of 100 cd m−2, demonstrating effective Förster resonance energy transfer (FRET) process. Therefore, employing these new bulky TMS substituent [3+2+1] iridium(III) complexes for effective sensitizers can greatly pave the way for further development of high efficiency and stable blue OLEDs in display and lighting applications.

Published: September 2023

AbstractCorannulene‐derived materials have been extensively explored in energy storage and solar cells, however, are rarely documented as emitters in light‐emitting sensors and organic light‐emitting diodes (OLEDs), due to low exciton utilization. Here, we report a family of multi‐donor and acceptor (multi‐D‐A) motifs, TCzPhCor, TDMACPhCor, and TPXZPhCor, using corannulene as the acceptor and carbazole (Cz), 9,10‐dihydro‐9,10‐dimethylacridine (DMAC), and phenoxazine (PXZ) as the donor, respectively. By decorating corannulene with different donors, multiple phosphorescence is realized. Theoretical and photophysical investigations reveal that TCzPhCor shows room‐temperature phosphorescence (RTP) from the lowest‐lying T1; however, for TDMACPhCor, dual RTP originating from a higher‐lying T1 (T1H) and a lower‐lying T1 (T1L) can be observed, while for TPXZPhCor, T1H‐dominated RTP occurs resulting from a stabilized high‐energy T1 geometry. Benefiting from the high‐temperature sensitivity of TPXZPhCor, high color‐resolution temperature sensing is achieved. Besides, due to degenerate S1 and T1H states of TPXZPhCor, the first corannulene‐based solution‐processed afterglow OLEDs is investigated. The afterglow OLED with TPXZPhCor shows a maximum external quantum efficiency (EQEmax) and a luminance (Lmax) of 3.3 % and 5167 cd m−2, respectively, which is one of the most efficient afterglow RTP OLEDs reported to date.

Published: September 2023

AbstractThe effectiveness of the adhesive was an important guarantee for the retard‐bonded prestressing technology. This study concentrated on quickly and reasonably predicting the service life of the adhesive. Samples of the adhesive were exposed in air circulating ovens set at 170, 190, and 210°C for various periods of time. The tensile shear strength of unaged and aged samples was tested. Two life prediction methods based on performance degradation data were presented in this paper. The improved Arrhenius model could improve the credibility and accuracy of extrapolation results meanwhile explains the non‐Arrhenius characteristics of adhesive at low temperature. The lifetime prediction result of the neural network model was close to that of the improved Arrhenius model. The conclusion is that the aging lifetime of adhesive is more than 70 years at an environment below 40°C. The research results provide direct and effective reference value for the life prediction of accelerated failure tests of adhesives.
Investigation of ZIF‐8, amine‐modified ZIF‐8 and polysulfone based mixed matrix membranes for CO2/CH4 separation
Authors: Jonnalagedda Aditya , Kuncharam Bhanu Vardhan Reddy 
Published: September 2023

AbstractMembrane separation is one of the techniques used for biogas upgradation. Mixed matrix membranes (MMMs) are currently being explored to overcome the trade‐off of selectivity‐permeability inherent in polymer membranes used for gas separation. A significant challenge associated with MMMs is the poor polymer‐metal–organic framework (MOF) filler interfacial compatibility, reducing the selectivity or permeability of gas. To address this issue, the present study focuses on the effect of the amine functionalization of ZIF‐8 to enhance the CO2 gas permeation without reducing the CO2/CH4 selectivity. MMMs were fabricated using unmodified ZIF‐8 and amine‐modified ZIF‐8 nanofillers dispersed in polysulfone at 5, 10, and 15 wt% loadings. MMMs were characterized by FTIR, DSC, TGA, and FESEM. X‐ray diffraction and FTIR analysis was conducted to verify the amine modification of ZIF‐8. Further, the performance of MMMs was tested with pure gasses (CO2 and CH4) and a model mixture of CO2 and CH4. In the mixed gas permeation test, the 10 wt% ZIF‐8 MMM exhibited the highest CO2 permeability of 25.4 Barrers, while 15 wt% NH2‐ZIF‐8 MMM exhibited the highest selectivity of 13.5. Notably, the ZIF‐8 MMMs demonstrated a 148% increase in CO2/CH4 selectivity, whereas the NH2‐ZIF‐8 MMMs exhibited a 155% increase compared to the pure polysulfone membrane.

AbstractSeit dem Jahr 1992 wurden die Mauerwerkseigenschaften in Form von zerstörenden und nicht zerstörenden Ziegel‐ und Mörteluntersuchungen im Zuge des Ingenieurbefunds an über 200 Gründerzeithäusern in Wien mit über 2000 Prüfstellen festgestellt und ausgewertet. Aus diesen Materialuntersuchungen lassen sich die Stein‐ und Mörteldruckfestigkeiten sowie deren Streuungen in Abhängigkeit von verschiedenen Einflussgrößen, wie Stockwerk, Lage der Wände im Gebäude, Geschossanzahl etc., angeben. Anhand der Gebäude‐Geodaten der Stadt Wien können auch die geografische Lage, der Bezirk, der Bautyp und die Bauperiode der Gebäude in die Untersuchungen mit einbezogen werden. Es wurde ein Datensatz mit 39.026 voneinander unabhängigen numerischen und kategorialen Daten erstellt und mittels Machine‐Learning‐Algorithmen und beschreibender Statistik analysiert. Mit den Verfahren konnten Korrelationen und Clusteranalysen bezüglich der Stein‐ und Mörteldruckfestigkeiten gefunden und die maßgeblichen Einflussgrößen zur Feststellung der Mauerwerksdruckfestigkeit identifiziert werden. Des Weiteren konnten auch die unterschiedlichen Untersuchungsmethoden evaluiert und daraus Empfehlungen abgeleitet werden. Mit den gewonnenen Erkenntnissen können die wesentlichsten Materialkennwerte, die im Rahmen der Tragfähigkeitsnachweise bzw. des Erdbebennachweises notwendig sind, vorweg beurteilt werden.

AbstractDer Einsatz von automatisierten Fertigungsverfahren auf Baustellen beruht auf den Grundlagen der industriellen Fertigung mit Industrierobotern. Infolge der bauspezifischen Besonderheiten können etablierte Standards hinsichtlich der Betriebssicherheit und des Arbeitsschutzes jedoch nur bedingt übernommen werden, obwohl gerade auf Baustellen von selbstständig agierenden Baumaschinen ein erhöhtes Gefahrenpotenzial ausgeht. In diesem Kontext stellt dieser Aufsatz neben spezifischen Grundlagen und dem Status quo der automatisierten Fertigung auf Baustellen die wichtigsten rechtlichen und normativen Randbedingungen zusammen und zieht daraus einen Rückschluss auf die Verantwortlichkeiten und die Umsetzung von Schutzmaßnahmen robotischer Anwendungen.
