AbstractAdhesives and water exhibit a conflicting correlation as indicated by the failure of most synthetic adhesives in submerged and humid environments. Development of instant, strong, reversible, and long‐lasting adhesives that can adhere to wet surfaces and function in underwater environments presents a formidable challenge, yet it is of paramount importance in biomedical and engineering applications. Herein, viscoelastic and moldable ionogels are developed based on synergistic engineering of aromatic substituents, fluorinated counterions, ionic building blocks, and 3D cross‐linked networks. The molecular design and structural engineering result in a facile synthesis, two bonding methods (glue‐ and tape‐type), and the combined mechanisms of enhanced adhesion and cohesion. The high underwater adhesion strength of over 8.9 MPa is among the best‐performing tape‐type underwater adhesives reported to date. A combination of excellent durability, reliability, deformation resistance, salt tolerance, water proof, antiswelling, and self‐healing properties demonstrates the “self‐contained” underwater adhesion. Furthermore, the extended π‐conjugation of the aromatic pendant groups confers a new functionality to the ionogels – visible fluorescence, enabling intriguing applications such as underwater labeling, information encryption, and signal transmission. This study shines lights on the fabrication of ionogel‐based adhesives and provides their future perspectives in underwater sealing, self‐repair, crack diagnosis, and informational labeling.

AbstractThe correlation between lattice chemistry and cation migration in high‐entropy Li+ conductors is not fully understood due to challenges in characterizing anion disorder. To address this issue, argyrodite family of Li+ conductors, which enables structural engineering of the anion lattice, is investigated. Specifically, new argyrodites, Li5.3PS4.3Cl1.7−xBrx (0 ≤ x ≤ 1.7), with varying anion entropy are synthesized and X‐ray diffraction, neutron scattering, and multinuclear high‐resolution solid‐state nuclear magnetic resonance (NMR) are used to determine the resulting structures. Ion and lattice dynamics are determined using variable‐temperature multinuclear NMR relaxometry and maximum entropy method analysis of neutron scattering, aided by constrained ab initio molecular dynamics calculations. 15 atomic configurations of anion arrangements are identified, producing a wide range of local lattice dynamics. High entropy in the lattice structure, composition, and dynamics stabilize otherwise metastable Li‐deficient structures and flatten the energy landscape for cation migration. This resulted in the highest room‐temperature ionic conductivity of 26 mS cm−1 and a low activation energy of 0.155 eV realized in Li5.3PS4.3Cl0.7Br, where anion disorder is maximized. This study sheds light on the complex structure–property relationships of high‐entropy superionic conductors, highlighting the significance of heterogeneity in lattice dynamics.

Published: September 2023

AbstractThe dynamic modulation of the plasticity of artificial neuromorphic devices facilitates a wide range of neuromorphic functions. However, integrating diverse plasticity modulation techniques into a single device presents a challenge due to limitations in the device structure design. Here, a multiterminal artificial synaptic device capable of bi‐directional modulation on its plasticity is proposed. Significantly, the conversion of inhibitory and excitatory synaptic plasticity can be achieved not only by modifying the polarity of the presynaptic voltage spike but also by exchanging its input terminal between top and bottom gate while maintaining the same presynaptic stimuli. This unique bi‐directional modulation of synaptic plasticity has been attributed to two distinct physical mechanisms: nonvolatile ferroelectric polarization and interface charge trap‐induced memory characteristics. Additionally, the effective dynamic modulation of the synaptic behaviors is quantified under different back‐gate bias and verified in the constructed neural network perceptron. Further, a visual simulation demonstrates the enhanced clarity and precision of edge recognition through the back‐gate modulation in the artificial synapses. This study provides a strategy to fulfill diversified modulation on synaptic plasticity in ferroelectric‐gated transistors, thereby prompting efficient and controllable neuromorphic visual systems.

Published: September 2023

AbstractUltracompact chiral plasmonic nanostructures with unique chiral light–matter interactions are vital for future photonic technologies. However, previous studies are limited to reporting their steady‐state performance, presenting a fundamental obstacle to the development of high‐speed optical devices with polarization sensitivity. Here, a comprehensive analysis of ultrafast chiroptical response of chiral gold nano‐oligomers using time‐resolved polarimetric measurements is provided. Significant differences are observed in terms of the absorption intensity, thus hot electron generation, and hot carrier decay time upon polarized photopumping, which are explained by a phenomenological model of the helicity‐resolved optical transitions. Moreover, the chiroptical signal is switchable by reversing the direction of the pump pulse, demonstrating the versatile modulation of polarization selection in a single device. The results offer fundamental insights into the helicity‐resolved optical transitions in photoexcited chiral plasmonics and can facilitate the development of high‐speed polarization‐sensitive flat optics with potential applications in nanophotonics and quantum optics.
Metallic and All‐Dielectric Metasurfaces Sustaining Displacement‐Mediated Bound States in the Continuum

Published: September 2023

AbstractBound states in the continuum (BICs) are localized electromagnetic modes within the continuous spectrum of radiating waves. Due to their infinite lifetimes without radiation losses, BICs are driving research directions in lasing, non‐linear optical processes, and sensing. However, conventional methods for converting BICs into leaky resonances, or quasi‐BICs, with high‐quality factors typically rely on breaking the in‐plane inversion symmetry of the metasurface and often result in resonances that are strongly dependent on the angle of the incident light, making them unsuitable for many practical applications. Here, an emerging class of BIC‐driven metasurfaces is numerically analyzed and experimentally demonstrated, where the coupling to the far field is controlled by the displacement of individual resonators. In particular, both all‐dielectric and metallic as well as positive and inverse displacement‐mediated metasurfaces sustaining angular‐robust quasi‐BICs are investigated in the mid‐infrared spectral region. Their optical behavior with regard to changes in the angle of incidence is investigated and experimentally shows their superior performance compared to two conventional alternatives: silicon‐based tilted ellipses and cylindrical nanoholes in gold. These findings are anticipated to open exciting perspectives for bio‐sensing, conformal optical devices, and photonic devices using focused light.

Published: September 2023

AbstractWhen the boiler is operated at different loads, the characteristics of ash deposition in the boiler will change accordingly. In this paper, a 660MW tangentially fired power boiler is taken as the research object. The combustion characteristics and ash deposition on the boiler walls are studied by numerical simulation. The results show that: 1) In the middle and lower part of the furnace wall, more particles are deposited, the temperature is higher and the CO concentration is higher, so slagging is easy to occur. 2) The ash accumulation in the bottom hopper mainly comes from the bottom two layers of burners for >98%. 3) The deposition ratio is negatively correlated with the height of the burner. 4) With the particle diameter increasing, the particle deposition from the lower burner increases significantly. Selecting pulverized coal with particle size of 65 µm can reduce the risk of ash deposition.

AbstractAimWhile surgery is essential for curative treatment of gastric cancer with oligometastasis, its target, timing, and possibility of combination with other treatments are unclear. We herein investigated the clinical course and long‐term outcomes of gastric cancer with oligometastasis in the real world setting to determine the optimal therapeutic strategy.MethodsThe present study retrospectively analyzed 992 patients who received any treatment for metastatic or recurrent gastric adenocarcinoma at Tokyo Metropolitan Komagome Hospital between 2007 and 2019. Oligometastasis was defined as any one of the following: liver metastases (HEP) <3; lung metastases (PUL) <3; unilateral adrenal gland metastasis (ADR); para‐aortic lymph node metastasis (PALN); or one, distant, lymph node metastasis, excluding the regional lymph nodes (LYM). Overall survival was compared by the characteristics and treatments for the oligometastasis, and univariate and multivariate analyses were used to identify the prognostic factors of overall survival.ResultsNinety‐seven patients (9.8%) with the following metastasis sites were enrolled: HEP (n = 27), PUL (n = 2), ADR (n = 3), PALN (n = 55), and LYM (n = 10). The median survival time of the cohort was 22.8 months, and the five‐year overall survival rate was 28.4%. On multivariate analysis, chemotherapy for the initial treatment (hazard ratio [HR]: 0.438; p = 0.048), distal gastrectomy and/or metastasectomy (HR: 0.290; p = 0.001), and R0 resection (HR: 0.373; p = 0.005) were identified as independent, positive factors of overall survival.ConclusionThe long‐term outcomes of gastric cancer in patients with oligometastasis may improve if treatment is begun with chemotherapy rather than surgery.
Photochemical Oximesulfonylation of Alkenes Using Sulfonyl‐Oxime‐Ethers as Bifunctional Reagents
Authors: Dey Jayanta , Banerjee Nayan , Daw Swikriti , Guin Joyram 
Published: September 2023

AbstractUtilization of oxime ethers as bifunctional reagents remains unknown. Herein, we present a mechanistically distinct strategy that enables oximesulfonylation of olefins using sulfonyl‐oxime‐ethers as bifunctional reagents under metal‐free photochemical conditions. Via concomitant C−S and C−C bond formation, the process permits incorporation of oxime and sulfonyl groups into olefins in a complete atom‐economic fashion, providing rapid access to multi‐functionalized β‐sulfonyl oxime ethers with good yields and stereoselectivity. The method is amenable to functionalization of complex bioactive molecules and is shown to be scalable. A radical chain mechanism initiated via photochemical Hydrogen Atom Transfer (HAT) mediated N−O bond cleavage is suggested for the process, based on our results on mechanistic investigations.

Published: September 2023

AbstractDie Abweichungen vom ersten Raoultschen Gesetz durch die Realgaskorrektur und das Flüssigkeitsvolumen in den Grenzgebieten der Konzentration, in denen nach der elementaren Theorie das Raoultsche Gesetz streng erfüllt sein sollte, ist selten experimentell überprüft worden. Die vorliegende Arbeit zeigt die Größe dieser Effekte am System Aceton/n‐Heptan. Hierzu wurden Dampfdruckgleichgewichte gemessen. Ferner wurde die Lage und Zusammensetzung des azeotropen Punktes des Systems zwischen 25 und 60°C so genau ermittelt, daß daraus eine Abschätzung des Verlaufs der Aktivitätskoeffizienten im ganzen Konzentrationsgebiet ermöglicht wird, die mit neueren Experimentalergebnissen verglichen werden kann. Schließlich werden noch einige Daten über den Azeotropismus des Systems Aceton/n‐Hexan mitgeteilt, aus dem ähnliche Schlüsse über den Verlauf der Aktivitätskoeffizienten im gesamten Konzentrationsgebiet gezogen werden können.

Published: September 2023

AbstractEs wird gezeigt, daß der Stromtransport im Dialuminiumtriäthyl‐Natriumfluorid und auch in dessen Lösungen mit Diäthyläther, Benzol und Toluol als Platzwechselvorgang aufzufassen ist. Die genannte Komplexverbindung bildet mit den benutzten Lösungsmitteln definierte Solvatationskomplexe. Am System Toluol‐Dialuminiumtriäthyl‐Natriumfluorid läßt sich nach abgeschlossener Solvatation die Temperatur‐und Konzentrationsabhängigkeit der spezifischen Leitfähigkeit mit Exponentialfunktionen und dem er‐mittelten Dissoziationsgleichgewicht der in Lösung dimer und monomer vorliegenden Verbindung beschreiben. Für den Platzwechsel über die monomere bzw. dimere Form des Dialuminiumtriäthyl‐Natriumfluorids sind unterschiedliche Aktivierungsenergien erforderlich.

Elektronenspektren einiger Molekülkomplexe im gesamten Quarz‐UV
Authors: Czekalla J. 
Published: September 2023

AbstractAus spektralphotometrischen Messungen an verdünnten Lösungen bei — 180 °C konnten die Bildungskonstanten Kc und damit die Absorptionsspektren der reinen Molekülverbindungen bis 210 mμ für folgende Komplexe rechnerisch ermittelt werden: Tetrachlorphthalsäureanhydrid‐Anthracen, ‐Hexamethylbenzol; Trinitrobenzol‐Anthracen, ‐Hexamethylbenzol; Tetracyanäthylen‐Hexamethylbenzol.Ein Vergleich der so gewonnenen Spektren mit den Spektren der Komponenten zeigt, daß die verschiedenen Banden durch die Komplexbildung recht unterschiedlich beeinflußt werden. Ein Verlust an Feinstruktur, geringfügige Blau‐ oder Rotverschiebung und nicht allzu starke Intensitätserhöhung oder ‐erniedrigung sind bei fast allen Banden festzustellen. Die Daten reichen nicht aus, um hierbei schon Gesetzmäßigkeiten zu erkennen. Nur für die symmetrieverbotene, langwelligste Bande des Hexamethylbenzols wurde in allen drei Komplexen eine starke Rotverschiebung und eine Intensitätserhöhung um etwa eine Zehnerpotenz gefunden, die praktisch einer Aufhebung des Übergangsverbots für den B2u ← A1g‐Übergang im Komplex gleichkommt.

Published: September 2023

AbstractEs wird ein Trennschema für alle Elemente, die bei der Kernspaltung des Urans (und der benachbarten Elemente) mit Isotopen von mehr als einem Tag Halbwertszeit entstehen, beschrieben. Die Trennung erfolgt an Ionenaustauschern, in einigen Fällen werden Destillationsverfahren benutzt. Nach einem oxydierenden Lösen der Probe wird zunächst Jod abdestilliert. Der Rückstand wird in konzentrierter Salzsäure auf einen stark basischen Anionenaustauscher gegeben. Die Elemente Ru, Zr, Cd, Nb, Np, Pu, Sb, U, Mo, Te und Sn werden adsorbiert und in Gruppen oder einzeln durch Salzsäure, Salzsäure‐Flußsäure, Flußsäure oder Perchlorsäure geeigneter Konzentration eluiert. Von den nicht adsorbierten Elementen werden Rh und Ag aus 1 n Salzsäure an einer zweiten Säule mit stark basischem Anionenaustauscher adsorbiert. Ebenfalls an diese Säule gelangen Zr und Cd, die von der ersten Säule gemeinsam desorbiert werden. Diese Elemente werden durch Salzsäure und Salpetersäure verschiedener Konzentration getrennt. Die Elemente As, Cs, Sr, Ba, Y und Seltene Erden passieren auch die zweite Säule; sie werden ‐ bis auf As ‐ an einem stark sauren Kationenaustauscher adsorbiert und mit Ammoniumchlorid (Cs), α‐Oxy‐isobuttersäure steigenden pH‐Wertes (Y, Seltene Erden) und Salzsäure (Sr, Ba) getrennt. Ru wird zwischen der ersten und zweiten Anionensäule abdestilliert. Der Einfluß verschiedener Variablen auf die Trennung wird erörtert.
Eine Druckwellenapparatur zur Messung von Relaxationsvorgängen in Lösungen
Authors: Hoffmann H. , Pauli K. 
Published: September 2023

AbstractEs wird eine Druckwellenapparatur zur Messung von Relaxationsvorgängen im Mikrosekundenbereich beschrieben. Durch Kondensatorentladungen über eine Flachspule vor einer Kupfermembran werden rechteckförmige Druckimpulse von etwa 12μsec Dauer und einer Amplitude von 25 atm erzeugt. Die dadurch ausgelösten chemischen Relaxationsvorgänge werden durch Messung der elektrischen Leitfähigkeit verfolgt. Das Verfahren erfaßt in seinem jetzigen Entwicklungsstand Relaxationszeiten zwischen 1 μsec und etwa 10 μsec und ergänzt daher die bisherige Drucksprungmethode. Die Ausdehnung des Meßbereiches zu kürzeren und auch längeren Zeiten ist möglich.Bei einer Anwendung des Verfahrens auf das Relaxationsverhalten von Co‐malonatlösungen wurden zwei verschiedene Relaxationszeiten beobachtet. Der Reaktionsmechanismus wird diskutiert.

Published: September 2023

AbstractBackgroundParkinson's disease (PD) is a common degenerative nervous system disease. At present, there are certain limitations in various treatment options aimed at preventing or delaying the progression of PD. Therefore, the exploration of new drugs for PD is beneficial. Mendelian randomization (MR) analysis can be used to explore the association between drugs and diseases. In this study, MR analysis was adopted to investigate the causal relationship between 23 drugs and PD. These drugs have been approved for the treatment of different diseases, such as salicylic acid and derivatives (collectively called salicylates, e.g., aspirin, used for fever and pain relief), antithrombotic agents (e.g., warfarin, aspirin, used for preventing thrombotic events).MethodsThe GWAS data for the 23 drugs were obtained from the UK Biobank (UKB) project, while the GWAS data for PD were sourced from FinnGen. Single‐Nucleotide Polymorphisms (SNPs) were selected as instrumental variables (IVs). We first performed a series of quality control steps (including MR‐PRESSO) to select the appropriate SNPs. Two‐sample MR analysis was performed using five different methods, including inverse variance weighting (IVW) with random‐effects model, weighted median, MR‐Egger, simple model, and weighted model. At the same time, sensitivity analysis was carried out using the MR‐Egger and Cochran's Q test to ensure the authenticity and reliability of the results.ResultsIn MR‐PRESSO, salicylates and antithrombotic agents showed statistically significant associations with PD, respectively. In the main MR analysis (IVW), there was a negative causal relationship between salicylates and PD (OR = 0.73, 95% CI = 0.54–0.98, p = .039). Similarly, there was a negative causal relationship between antithrombotic agents and PD (OR = 0.70, 95%CI = 0.52–0.96, p = .027). No statistically significant association was found between the remaining 21 drugs and PD.ConclusionThis MR study demonstrated that salicylates and antithrombotic agents can reduce the risk of PD, thus providing a novel avenue for future drug exploration in PD.

AbstractMultiple sclerosis (MS) is a life‐threading disease that poses a great threat to the human being lifestyle. Having said extensive research in the realm of underlying mechanisms and treatment procedures, no definite remedy has been found. Over the past decades, many medicines have been disclosed to alleviate the symptoms and marking of MS. Meanwhile, the substantial efficacy of herbal medicines including curcumin must be underscored. Accumulated documents demonstrated the fundamental role of curcumin in the induction of the various signaling pathways. According to evidence, curcumin can play a role in mitochondrial dysfunction and apoptosis, autophagy, and mitophagy. Also, by targeting the signaling pathways AMPK, PGC‐1α/PPARγ, and PI3K/Akt/mTOR, curcumin interferes with the metabolism of MS. The anti‐inflammatory, antioxidant, and immune regulatory effects of this herbal compound are involved in its effectiveness against MS. Thus, the present review indicates the molecular and metabolic pathways associated with curcumin's various pharmacological actions on MS, as well as setting into context the many investigations that have noted curcumin‐mediated regulatory effects in MS.
