Published: October 2023

AbstractMicro‐patterning silver nanowires (AgNWs) via solution processes is vital in making high‐performance transparent flexible electrodes (TFE) that have been widely used in optoelectronic devices. However, it has suffered from the limitation of a trade‐off relationship between the coverage and the arrangement of AgNWs, which determine the transparency and the conductivity, respectively. Here, unique AgNWs micro‐patterns, featuring as the crossing‐grid of high‐resolution and highly‐aligned AgNWs micro‐lines, which enable the micro‐pattern highly cross‐aligned with a limited 3.9% coverage, are developed. Consequently, a TFE with an ultra‐high transmittance over 98.5% and a sheet resistance of 25.5 Ω sq−1 is developed. Guided by the unit of triple conical fibers, AgNWs are controllable transferred onto the target area, leaving a line with a width‐resolution up to 2 µm. Simultaneously, AgNWs are aligned under the synergistic effect of both the solution‐shearing and the tri‐phase contact line confinement. Using the as‐developed TFE as either the top or the bottom electrode, a transparent quantum dot light‐emitting diode (T‐QLED) with a transmittance of 89.8%, as well as a flexible T‐QLED with a transmittance of 92.8% are demonstrated, much higher than those of T‐QLEDs reported. It is envisioned that the result would inspire the fabrication of high‐performance transparent optoelectronic devices.

AbstractNanoengineering the composition and morphology of functional nanoparticles endows them to perform multiple tasks and functions. An intriguing strategy for creating multifunctional nanomaterials involves the construction of core–shell nanostructures, which have enabled promising applications in biomedicine, energy, sensing, and catalysis. Here, a straightforward nanoengineering approach is presented utilizing liquid metal nanoparticles and galvanic replacement to create diverse core–shell nanostructures. Controlled nanostructures including liquid metal core‐gold nanoparticle shell (LM@Au), gold nanoparticle core‐gallium oxide shell (Au@Ga oxide), and hollow Ga oxide nanoparticles are successfully fabricated. Remarkably, these investigations reveal that LM@Au exhibits exceptional photothermal performance, achieving an impressive conversion efficiency of 65.9%, which is five times that of gold nanoparticles. By leveraging the high photothermal conversion efficiency and excellent biocompatibility of LM@Au, its promising application in hyperthermia cancer therapy is demonstrated. This simple yet powerful nanoengineering strategy opens new avenues for the controlled synthesis of complex core–shell nanostructures, advancing various fields beyond biomedicine.

AbstractMetal halide perovskite single crystals (MHP‐SCs) are known for their facile fabrication into large sizes using inexpensive solution methods. Owing to their combination of large mobility‐lifetime products and strong X‐ray absorption, they are considered promising materials for efficient X‐ray detection. However, they suffer from large dark currents and severe ion migration, which limit their sensitivity and stability in critical X‐ray detection applications. Herein, a heterointerface design is proposed to reduce both the dark current and ion migration by forming a heterojunction. In addition, the carrier transport performance is significantly improved using heterointerface engineering by designing a gradient band structure in the SCs. The SC heterojunction detectors exhibit a high sensitivity of 3.98 × 105 µC Gyair−1 cm−2 with a low detection limit of 12.2 nGyair s−1 and a high spatial resolution of 10.2 lp mm−1 during imaging. These values are among the highest reported for state‐of‐the‐art MHP X‐ray detectors. Moreover, the detectors show excellent stability under continuous X‐ray irradiation and maintainclear X‐ray imaging after 240 d. This study provides novel insights into the design and fabrication of X‐ray detectors with high detection efficiency and stability, which are beneficial for developing inexpensive, high‐resolution X‐ray imaging equipment.

AbstractThe assembly of hybrid materials combining a pure sp3‐C platform from nano‐and microcrystals of molecularly‐defined nanometer‐sized functionalized diamondoids (nanodiamonds) coated with a gold transition metal nanolayer is conducted from the gas phase, following a two‐steps vapor phase dry construction process. By using first the controlled vapor phase self‐assembly of primary phosphine diamantane derivatives, followed by a chemical vapor decomposition of a suited gold organometallic complex the synthesis of the nanocomposite Au@H2P–DiamOH 2 is achieved. The gold deposit surface analysis reveals the formation of a Au–P covalent bonding, which excludes the formation of phosphine oxide, as confirmed at higher depth into the nanocomposite by Hard X‐ray Photoelectron Spectroscopy analysis (HaXPES). The thickness d of the gold layers deposited onto the surface of diamondoids is estimated to be around d = 0.8 ± 10% nm from XPS data, which allows combining the composite Au@H2P–DiamOH 2 with ITO interdigitated electrodes, to produce a long‐life, highly stable and reproducible, n‐type behavior sensor for ammonia detection. A relative response (RR) of 150% at 30 ppm and a limit of detection of 6 ppm are measured at room temperature (20 to 25 °C) and at 45% of relative humidity.

Published: October 2023

AbstractAlkaline‐earth metal cations impact the rate of crystallization and the adsorption of N2 and CO2 on nanosized chabazite zeolites. In this study, either calcium or barium is added to precursor mixtures containing alkali‐metal cations (Na+, K+, Cs+) to prepare chabazite (labeled Ca‐CHA and Ba‐CHA), and are compared to a reference sample (Ref‐CHA) synthesized using exclusively Na+, K+, and Cs+. Partial substitution of the Na+ and the pore‐blocking Cs+ extra‐framework cations is observed for Ca‐CHA depending on the molar ratio of K2O used in the synthesis, while a change to the amount of Na+ cations only is observed for Ba‐CHA. The type of alkaline‐earth metal cation affects the crystallization rate; slower in the presence of Ca2+ (10 h to full crystallinity) and similar rates in the presence of Ba2+ (4 h to full crystallinity); the crystallite size and morphology remained similar. The presence of Ca2+ or Ba2+ extra‐framework cations leads to N2 uptake values of 290 and 169 mmol g−1 (−196 °C, 100 kPa), respectively, while at low CO2 pressure (<1 kPa, 25 °C), the physisorbed CO2 capacity for Ref‐CHA, Ca‐CHA, and Ba‐CHA zeolites is 0.63, 0.66, and 0.59 mmol g−1, respectively. Interestingly, an opposite effect is observed for the amount of chemisorbed CO2 species.

AbstractCoevolution of tumor cells and surrounding stroma results in protective protumoral environment, in which abundant vessel, stiff structure and immunosuppression promote each other, cooperatively incurring deterioration and treatment compromise. Reversing suchenvironment may transform tumors from treatment‐resistant to treatment‐vulnerable. However, effective reversion requires synergistic comprehensive regression of such environment under precise control. Here, the first attempt to collaboratively retrograde coevolutionary tumor environment to pre‐oncogenesis status, defined as tumor environment regression therapy, is made for vigorous immune response eruption by a switchable prune‐to‐essence nanoplatform (Pres) with simplified composition and fabrication process. Through magnetic targeting and multimodal imaging of Pres, tumor environment regression therapy is guided, optimized and accomplished in a trinity way: Antiangiogenesis is executed to rarefy vessels to impede tumor progression. By seizing the time, cancer associated fibroblasts are eliminated to diminish collagen and loosen the stiff structure for deep penetration of Pres, which alternately functioned in deeper tumors, forming a positive feedback loop. Through this loop, immune cell infiltration, immunosuppression mitigation and immunogenic cells death induction are all fulfilled and further escalated in the regressed environment. These transformations consequently unleashed systemic immune responses and generated immune memory against carcinoma. This study provides new insights intotreatment of solid tumors.

AbstractJanus membranes with asymmetric wettability have been considered cutting‐edge for energy/environmental‐sustainable applications like water/fog harvester, breathable skin, and smart sensor; however, technical challenges in fabrication and accurate regulation of asymmetric wettability limit their development. Herein, by using water‐assisted hydrogen‐bonded (H‐bonded) assembly of small molecules at water/oil interface, a facile strategy is proposed for one‐step fabrication of membranes with well‐regulable asymmetric wettability. Asymmetric orderly patterns, beneficial for mass transport based on abundant high‐permeability sites and large surface area, are constructed on opposite membrane surfaces. Upon tuning water‐assisted H‐bonding via H‐sites/configuration design and temperature/pH modulation, double‐hydrophobic, double‐hydrophilic, and hydrophobic‐hydrophilic membranes are facilely fabricated. The Janus membranes show smart vapor‐responsive curling and unidirectional water transport with promising flux of 1158±25 L m−2 h−1 under natural gravity and 31500±670 L·(m−2 h−1 bar−1) at negative pressure. This bottom‐up approach offers a feasible‐to‐scalable avenue to precise‐manipulation of Janus membranes for advanced applications, providing an effective pathway for developing tailor‐made self‐assembled nanomaterials.

Published: October 2023

AbstractThis paper discusses differences in the likelihood of loan default between Black and other farmers who took out USDA direct operating loans from 2011 to 2020. By controlling for financial, demographic, and other factors using a Cox proportional hazards model, we found that Black farmers have a higher incidence of default than other farmers. We advanced the research on the relative loan performance of different racial/ethnic minority groups, revealing heterogeneity in the likelihood of default that indicates using a single grouping for all minorities obscures important differences. There could be multiple contributing factors to higher rates of default among Black borrowers that deserve future attention and study, though it is beyond the scope of this paper to identify a causal mechanism.

AbstractINTRODUCTIONWhether the integration of eye‐tracking, gait, and corresponding dual‐task analysis can distinguish cognitive impairment (CI) patients from controls remains unclear.METHODSOne thousand four hundred eighty‐one participants, including 724 CI and 757 controls, were enrolled in this study. Eye movement and gait, combined with dual‐task patterns, were measured. The LightGBM machine learning models were constructed.RESULTSA total of 105 gait and eye‐tracking features were extracted. Forty‐six parameters, including 32 gait and 14 eye‐tracking features, showed significant differences between two groups (P < 0.05). Of these, the Gait_3Back‐TurnTime and Dual‐task cost‐TurnTime patterns were significantly correlated with plasma phosphorylated tau 181 (p‐tau181) level. A model based on dual‐task gait, dual‐task smooth pursuit, prosaccade, and anti‐saccade achieved the best area under the receiver operating characteristics curve (AUC) of 0.987 for CI detection, while combined with p‐tau181, the model discriminated mild cognitive impairment from controls with an AUC of 0.824.DISCUSSIONCombining dual‐task gait and dual‐task eye‐tracking analysis is feasible for the detection of CI.Highlights
This is the first study to report the efficiency of integrated parameters of dual‐task gait and eye‐tracking for cognitive impairment (CI) detection in a large cohort.
We identified 46 gait and eye‐tracking features associated with CI, and two were correlated to plasma phosphorylated tau 181.
We constructed the model based on dual‐task gait, smooth pursuit, prosaccade, and anti‐saccade, achieving the best area under the curve of 0.987 for CI detection.

AbstractDevelopment of a Membraneless Vanadium Micro Redox Flow Battery (MVMRFB) with an automated closed‐loop control, using micro actuators and micro sensors, is presented for the first‐time during electrolyte preconditioning operation in recirculation mode. The progress of preconditioning is tracked with UV‐vis spectroscopy by 3D printed micro flow cuvettes. Influence of flow rate, reactor internal resistance, and presence of side reactions in the preconditioning process are studied. Optimal flow rate ratio between negative and positive electrolytes is determined and significant performance improvements achieved by operating at lower flow rates are obtained. Influence of reactor internal resistance, which is directly related with the maximum power density, is evaluated demonstrating that operating at a high‐power density can be a source of inefficiency due to the presence of side reactions. Finally, presence of side reactions is evaluated through a dual measurement of electrolytes concentrations in both negative and positive side, and it is demonstrated to be a cause for charge imbalance between the two half‐cells. This work lays a solid foundation for the successful implementation of a charge‐discharge cycle in MVMRFBs operating in recirculation mode.
Die UHFB‐Biegedatenbank

Published: October 2023

AbstractIn dieser Arbeit werden Versuchsdaten von 228 Biegeträgern aus ultrahochfestem Beton (UHFB) in einer Datenbank zusammengeführt. Berücksichtigung finden unterschiedliche Querschnittsformen und Bewehrungskonfigurationen, einschließlich vorgespannter, rein stahlfaserbewehrter und rein stabstahlbewehrter Bauteile. Bei der Auswertung der Quellen zeigt sich, dass wichtige Werkstoffkenngrößen vielfach nur unzureichend dokumentiert vorliegen. Zudem erschwert der Einsatz unterschiedlicher, häufig nicht normierter Methoden der Werkstoffcharakterisierung die Vergleichbarkeit der einzelnen Studien. Daher werden sämtliche Daten zunächst sorgfältig geprüft, normiert und in Teilen ergänzt. Anschließend erfolgt mit den Datensätzen der Datenbank die Validierung eines unter Beteiligung der Autoren entstandenen und hier für die Anwendung auf komplexe Querschnittsgeometrien aufbereiteten Ansatzes zur Biegebemessung kombiniert bewehrter Biegeträger. Bei der Auswertung mit den Mittelwerten der Werkstoffkenngrößen wird sowohl für die Gesamtheit der Versuche als auch für einzelne Modellparameter eine gute Modellpassung erzielt. Ein akzeptables Sicherheitsniveau wird erreicht, wenn der charakteristische Wert der Nachrisszugfestigkeit auf den 0,6‐fachen Mittelwert begrenzt wird. Das 5%‐Quantil des Verhältnisses zwischen experimenteller und rechnerischer Biegetragfähigkeit Mexp / Mcal beträgt dann Q0,05 = 0,97 für die Gesamtheit der 228 Datensätze.

AbstractNeuropilin 1 (NRP‐1) inhibition has shown promise in reducing the infectivity of severe acute respiratory syndrome‐coronavirus‐2 (SARS‐CoV‐2) and preventing the virus entry into nerve tissues, thereby mitigating neurological symptoms in COVID‐19 patients. In this study, we employed virtual screening, including molecular docking, Molecular Dynamics (MD) simulation, and Molecular Mechanics‐Poisson Boltzmann Surface Area (MM‐PBSA) calculations, to identify potential NRP‐1 inhibitors. From a compendium of 1930 drug‐like natural compounds, we identified five potential leads: CNP0435132, CNP0435311, CNP0424372, CNP0429647, and CNP0427474, displaying robust binding energies of −8.2, −8.1, −10.7, −8.2, and −8.2 kcal/mol, respectively. These compounds demonstrated interactions with critical residues Tyr297, Trp301, Thr316, Asp320, Ser346, Thr349, and Tyr353 located within the b1 subdomain of NRP‐1. Furthermore, MD simulations and MM‐PBSA calculations affirmed the stability of the complexes formed, with average root mean square deviation, radius of gyration, and solvent accessible surface area values of 0.118 nm, 1.516 nm, and 88.667 nm2, respectively. Notably, these lead compounds were estimated to penetrate the blood‐brain barrier and displayed antiviral properties, with Pa values ranging from 0.414 to 0.779. The antagonistic effects of these lead compounds merit further investigation, as they hold the potential to serve as foundational scaffolds for the development of innovative therapeutics aimed at reducing the neuroinfectivity of SARS‐CoV‐2.

AbstractWe report an efficient and eco‐friendly method for the Vitreoscilla hemoglobin (VHb)‐catalyzed synthesis of benzoxazoles in water at room temperature. tert‐Butyl hydroperoxide and 2,2,6,6‐tetramethyl‐1‐piperidinyloxy were used as oxidant and radical scavenger, respectively. A total of 27 functionally diverse benzoxazoles were prepared in moderate to high yields (62 %‐94 %) by the annulation reaction of phenols with amines in the presence of VHb in 1 h. Thus, this method is highly viable for practical applications. This work broadens the application of hemoglobin to organic synthesis.

Published: October 2023

AbstractBackground and ObjectivesProcessing parameters of yellow pea (Pisum sativum L.) flour‐fortified gluten‐free (GF) bread was optimized by response surface methodology (RSM). The final bread product was evaluated for quality, sensory acceptability, and shelf life. A second‐order model was fitted to the precooking temperature of whole pea (PTWP), water level, and proof time as the factors used in RSM.FindingsHigher PTWP and lower proof time had significantly (p < .05) lower bread crumb brightness compared to other treatments. Crumb firmness was influenced by the PTWP, water level, and proof time. The optimized parameters for PTWP, water level, and proof time were 156.9°C, 523.8 g, and 18.0 min, respectively. The optimized bread had a brightness (L* value), specific volume, crumb firmness, and mean cell diameter of 68.20, 2.6 mL/g, 174.2 gf, and 3.81 mm, respectively. The optimized GF bread had longer shelf‐life but had significantly (p < .05) lower acceptance scores, than the commercial premix GF bread product.ConclusionThe optimized processing parameters for yellow pea utilization in gluten‐free bread were identified by RSM resulting in optimized quality characteristics of the finished baked product.Significance and NoveltyThe principles of RSM were an excellent tool to optimize the physical attributes of gluten‐free bread formulated with yellow pea flour.

Published: October 2023

AbstractPorous organic polymers (POPs) – the emergent hydrothermally stable, amorphous and porous materials – have proven to be invaluable for catalytic applications. Through a rational bottom‐up design, we have developed a Carboxy‐POP, a POP that is adorned by Bronsted acid (COOH) functionalities, for heterogeneous catalysis. The Carboxy‐POP has been comprehensively characterized by FT‐IR, solid‐state 13C NMR, SEM, TEM, etc. It exhibits a moderate porosity with a BET surface area of 381 m2 g−1 and acid concentration of 1.67 mmol/g. Its functional utility as an efficient heterogeneous catalyst for one‐pot synthesis of a variety of xanthenes and acridines in excellent isolated yields (up to 98 %) is demonstrated. In contrast to the conventional methods, the advantages of the reported metal‐free catalytic protocol include ease of operation, excellent isolated yields of the products, facile workup, and shorter reaction times. It is shown that the heterogeneous catalyst can be repetitively used with the catalytic activity almost intact even after 16 reaction cycles.
