AbstractThe development of thermally driven water‐sorption‐based technologies relies on high‐performing water vapor adsorbents. Here, polymorphism in Al–metal–organic frameworks is disclosed as a new strategy to tune the hydrophilicity of MOFs. This involves the formation of MOFs built from chains of either trans‐ or cis‐ µ‐OH‐connected corner‐sharing AlO4(OH)2 octahedra. Specifically, [Al(OH)(muc)] or MIP‐211, is made of trans, trans‐muconate linkers, and cis‐µ‐OH‐connected corner‐sharing AlO4(OH)2 octahedra giving a 3D network with sinusoidal channels. The polymorph MIL‐53‐muc has a tiny change in the chain structure that results in a shift of the step position of the water isotherm from P/P0 ≈ 0.5 in MIL‐53‐muc, to P/P0 ≈ 0.3 in MIP‐211. Solid‐state NMR and Grand Canonical Monte Carlo reveal that the adsorption occurs initially between two hydroxyl groups of the chains, favored by the cis‐positioning in MIP‐211, resulting in a more hydrophilic behavior. Finally, theoretical evaluations show that MIP‐211 would allow achieving a coefficient of performance for cooling (COPc) of 0.63 with an ultralow driving temperature of 60 °C, outperforming benchmark sorbents for small temperature lifts. Combined with its high stability, easy regeneration, huge water uptake capacity, green synthesis, MIP‐211 is among the best adsorbents for adsorption‐driven air conditioning and water harvesting from the air.

Published: March 2023

AbstractThe electronic structure and thermoelectric properties of MoX2 (X = S, Se) Van der Waals heterojunctions are reported, with the intention of motivating the design of electronic devices using such materials. Calculations indicate the proposed heterojunctions are thermodynamically stable and present a band gap reduction from 1.8 eV to 0.8 eV. The latter effect is highly related to interactions between metallic d‐character orbitals and chalcogen p‐character orbitals. The theoretical approach allows to predict a transition from semiconducting to semi‐metallic behavior. The band alignment indicates a type‐I heterojunction and band offsets of 0.2 eV. Transport properties show clear n‐type nature and a high Seebeck coefficient at 300 K, along with conductivity values (σ/τ) in the order of 1020. Lastly, using the Landauer approach and ballistic transport, the proposed heterojunctions can be modeled as a channel material for a typical one‐gate transistor configuration predicting subthreshold values of ≈60 mV dec−1 and field–effect mobilities of ≈160 cm−2 V−1 s−1.
Nonlinear Chiral Metasurfaces Based on the Optical Kerr Effect

Published: March 2023

AbstractChiral nanostructures have immense potential for complete polarization control of light. Given the intrinsic 3D structure of circularly polarized light, nanoarchitectures with structural chirality in 3D space are usually required to achieve “full” chiroptical response. On the other hand, due to the lack of available active materials at optical wavelengths, examples of chiral photonic devices that can be tuned in an active manner remain rare. Here, based on the large Kerr nonlinearities of silicon, the nonlinear chiroptical response from a planar Si metasurface supporting high quality (Q)‐factor guided mode resonances (GMRs) at near‐infrared wavelengths, are numerically demonstrated. In the linear regime, the optical anisotropy of the C2‐symmetric structure associated with the observed GMRs leads to a pair of chiral resonance modes, enabling pronounced cross‐polarization transmission circular dichroism and a strong handedness‐dependent field enhancement effect. Owing to the nonlinear Kerr effect, such Si metasurfaces are seen to exhibit prominent chiral‐selective optical nonlinearity. Importantly, a pronounced co‐polarization transmission circular dichroism is observed, suggesting that the circularly polarized waves in the nonlinear regime possess asymmetric Jones matrices. Dielectric chiral metasurfaces with Kerr nonlinearities can be utilized to facilitate polarization‐state modulators with simple planar structures.

Published: March 2023

AbstractIntegrating broadband absorption, dynamic tunability, and high optical transparency into a single microwave absorber remains a crucial challenge. Here, an ultra‐broadband, tunable, and transparent microwave meta‐absorber comprising double‐layer indium tin oxide resonant patterns and a water‐based substrate is theoretically presented and experimentally demonstrated. Experimental measurements indicate that the designed meta‐absorber can achieve over 90% absorption in an ultra‐broadband frequency range of 12.49–98.21 GHz with a relative bandwidth of 154.9%, while the average optical transmittance is 60.49%. In addition, a multiple reflections interference model is employed to elucidate the physical mechanisms of the ultra‐broadband absorber. Furthermore, its absorption performance can be reversibly switched between ultra‐broadband and dual‐broadband by altering the water substrate thickness. These peculiar properties make the proposed meta‐absorber more favorable for practical applications in modern stealth materials and optical windows.

AbstractDistinct from conventional optical lenses suffering from the diffraction limit, the superoscillatory lens offers an alternative approach to realize far‐field sub‐diffraction focusing and find significant applications in both microscopy and telescopy. During the past few years, planar micro/nanostructures are unitized to precisely manipulate the optical fields through a standard lens to realize a superoscillatory field along the radial direction of the pupil. Here, an angular superoscillatory metalens (ASOM) is demonstrated by combining the superoscillatory phase and angular metalens phase in a single metasurface. To the best of the authors’ knowledge, this is the first work that focuses on the angular superoscillatory phenomenon. As a proof‐of‐concept application demo, this study shows the ASOM can map the received orbital angular modes (OAMs) into focusing patterns at the focal plane with different azimuth angles. Therefore, the OAM spectrum incorporating multiple modes can be determined with a single‐shot measurement according to the precalibrated mapping relationship. This study shows that the OAM resolution is scaled up about 3.2 times compared with a normal angular metalens, thanks to the shrinkage of the focal patterns. This approach may push the development of integrated and high‐dimensional optical and quantum systems.

AbstractAn operationally simple aqueous phase three‐component photochemical strategy for the alkylation of quinoxalin‐2(1H)‐ones with diethyl α‐bromomalonate and unactivated alkenes in the absence of both photoredox catalysts and additive has been developed. This reaction is driven by the photochemical activity of electron donor‐acceptor (EDA) complexes formed by quinoxalin‐2(1H)‐ones and diethyl α‐bromomalonate. Irradiation with visible light triggered single‐electron transfer (SET) from the quinoxalin‐2(1H)‐ones to the diethyl α‐bromomalonate, inducing the formation of the corresponding alkyl radical and the subsequent radical tandem reaction. It provides an efficient way to construct alkylated quinoxalinones from simple small molecules.magnified image

AbstractThe outbreak of the global pandemic has aroused significant attention from the public for healthy living environments. From this point of view, chemical sensors are crucial since these devices or actuators have diverse applications, such as environmental monitoring, food safety, industry, and healthcare. The development of chemical sensors may substitute human senses and precisely identify unspecified substances or discriminate materials accurately. For the implementation of chemical sensors utilized in daily life, there are requirements such as portability, low cost, low power consumption, high selectivity, and sensitivity. The most adequate materials are 2D materials that exactly agree with the described conditions. 2D materials have been studied for sensor applications owing to their unique material characteristics specialized for detecting particular substances. High surface to volume ratio or numerous reaction sites are representative physical properties of 2D materials. Furthermore, high carrier mobility is a typical feature of these substances appropriate for manufacturing advanced chemical sensors. Herein, the history and recent advances of 2D material‐based chemical sensors along with a description of perspectives and future challenges are introduced. This review provides a guideline for preparing chemical sensors based on 2D materials as next‐generation sensing devices.

AbstractTransdermal drug delivery is a promising strategy characterized by minor fluctuations in blood concentrations, few adverse effects, convenience, and excellent patient compliance, especially for biomacromolecules. Conversely, traditional delivery methods are limited by their poor penetration abilities and complex preparation and application techniques. However, some inherent properties of biomacromolecules, such as large sizes, complex structure, and poor stability, can affect their ability to overcome skin barriers and reach deeper layers. Ionic liquids (ILs) are organic salts composed of asymmetric cations and anions in liquid form below 100 °C. ILs provide excellent protection for biomacromolecules and can facilitate their passage through the stratum corneum to cells for therapeutic effects. Therefore, they represent one of the most promising approaches to promoting transdermal penetration. Here, the barriers to effective transdermal delivery, including skin properties and the stability and biocompatibility of IL‐based biomacromolecule formulations, are highlighted and the current status of IL‐based biomacromolecule formulations are focused on, the tremendous advantages of using ILs based on current challenges in transdermal drug delivery are discussed, and light is shed on several ILs frequently used in the delivery of biomacromolecules.

Published: March 2023

AbstractEpsilon‐near‐zero (ENZ) photonics, which exhibit extraordinary capabilities in terms of controlling light–matter interactions, have been attracting increased interest in recent years. However, several challenges still lie ahead, such as large optical loss and the rarity of ENZ candidates, especially in the visible range. Here, by first‐principles calculations, this work proposes dozens of MXenes with promising plasmonic properties that could be potential ENZ candidates with very low loss in the visible range by band structure engineering. Because of the special electronic structures of these MXenes, they all possess quite large screened plasmonic frequencies: , but less than the interband transition onsets, which cause the ENZ properties in these MXenes to appear in the visible range with very low loss (ε2 less than 0.2) by eliminating the interband transition loss at the ENZ frequencies. Furthermore, it is also demonstrated that the ENZ properties in MXenes, including the ENZ frequency and loss, can be effectively tuned upon surface modifications, such as −Cl and −OH. These outstanding ENZ properties, including tunablity and low‐loss, make these MXenes great for potential applications in ENZ photonics, especially in the visible‐light range.

AbstractIt is anticipated that perovskite solar cells (PSCs) will overtake other products in the market for next‐generation photovoltaics. The optical loss, however, continues to be a flaw that restricts the photocurrent (Jph) of PSCs. Mesoporous antireflection coatings (ARCs), both monolayer and multilayer, are designed using a combination of the finite element method and equivalent medium theory, and ARCs models are merged with PSCs. In the current work, mesoporous ARCs are made, the optical performance of the device is evaluated using optical modeling, and then the ARCs are integrated into solar cells. The simulation results show that the Jph of planar inverted PSCs can increase to 24.00 mA cm−2 when the front surface of PSCs adopts mesoporous ARC (via parameter optimization and sensible arrangement and combination). An increase of 0.98 mA cm−2 in Jph of PSCs is observed in comparison with flat ARC (23.02 mA cm−2). The strong light transmission and low reflection properties of the mesoporous ARCs are confirmed by the optimized solution. It is important to note that the first fusion of mesoporous and multilayer ARC offers a fresh approach to the development of perovskite and perovskite/silicon tandem solar cells with extremely high efficiency.

AbstractAbnormal vibration is a direct response to the mechanical defects of electrical equipment, and requires reliable vibration sensing for health condition evaluation in the associated system. The triboelectric nanogenerator (TENG) triggered by random vibration to generate electrical energy/signal while giving feedback on the vibration state, paving a promising way towards self‐powered sensors. Here, an all‐in‐one sensing system configured with a vibration sensor demonstrates instantaneous discharge boosted TENG and IR wireless communication for vibration state online monitoring. The sandwich‐structured TENG combined with mechanical switches can release the co‐accumulated charges from dual triboelectric layers to yield giant instantaneous output power of 616 W, which is 106 times higher than that of the continuous discharge. Moreover, an IR LED as a transmitter driven by the TENG can form an all‐in‐one vibration sensor enabling wireless communication, where the sensor can be further integrated with repeaters and phones to establish a wireless vibration online monitoring system for vibration state visualization. This work presents a novel idea to implement high‐power TENG with IR communication integration for in situ vibration online monitoring. Such a strategy is potentially available for distributed sensor construction towards abnormal signal monitoring that reflects the operating state of equipment.

Authors: Zhao Hui , Yuan Zhong‐Yong 
Published: March 2023

AbstractSolar‐driven water electrolysis has been considered to be a promising route to produce green hydrogen, because the conventional water electrolysis system is not completely renewable as it requires power from nonrenewable fossil fuel sources. This review emphasizes the strategies for solar‐driven water electrolysis, including the construction of photovoltaic (PV)‐water electrolyzer systems, PV‐rechargeable energy storage device‐water electrolyzer systems with solar energy as the sole input energy, and photoelectrochemical water splitting systems. The basic discussions of the above strategies for solar‐driven water electrolysis are first presented. Meanwhile, replacing the oxygen evolution reaction with the electrooxidation of organic compounds can effectively improve the efficiency of water splitting. Also, solar‐driven seawater electrolysis greatly broadens the practical applications due to the abundant reserves of seawater. Recent years have witnessed great development in the field of solar‐driven water electrolysis. The recent research development in the area is subsequently reviewed. Finally, perspectives on the existing challenges along with some opportunities for the further development of solar‐driven water electrolysis are provided.

AbstractHerein; we report protocols for the synthesis of 1,2,4‐triazoles and 1,3,4‐ thiadiazinones by [3+2] and [3+3] domino annulation reactions of nitrile imines with succinimide and thiazolidine‐2,4‐dione, respectively, using a base (1.5 equivalents) and alcohol as a solvent. In these reactions, notably, alcohol serves not only as a solvent but also as a reactant participating in the formation of ester functionality in products. These methodologies provide metal‐free and direct approaches to the synthesis of 1,2,4‐triazoles and 1,3,4‐thiadiazinones under mild conditions with a wide substrate scope and high yields.

AbstractBackgroundChronic exposure to particulate matter air pollution (PM2.5) is associated with chronic rhinosinusitis (CRS). Elevated ambient temperature may increase PM2.5 levels and thereby exacerbate sinonasal symptoms. This study investigates the association between high ambient temperature and the risk of CRS diagnosis.MethodsPatients with CRS were diagnosed at Johns Hopkins hospitals from May to October 2013–2022, and controls were matched patients without CRS meanwhile. A total of 4752 patients (2376 cases and 2376 controls) were identified with a mean (SD) age of 51.8 (16.8) years. The effect of maximum ambient temperature on symptoms was estimated with a distributed lag nonlinear model (DLNM). Extreme heat was defined as 35.0°C (95th percentile of the maximum temperature distribution). Conditional logistic regression models estimated the association between extreme heat and the risk of CRS diagnosis.ResultsExposure to extreme heat was associated with increased odds of exacerbation of CRS symptoms (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.03–1.19). The cumulative effect of extreme heat during 0–21 lag days was significant (OR 2.37, 95% CI 1.60–3.50) compared with the minimum morbidity temperature (MMT) at 25.3°C. Associations were more pronounced among young and middle‐aged patients and patients with abnormal weight.ConclusionsWe found that short‐term exposure to high ambient temperature is associated with increased CRS diagnosis, suggesting a cascading effect of meteorological phenomena. These results highlight climate change's potentially deleterious health effects on upper airway diseases, which could have a significant public health impact.

ObjectiveTo evaluate clinical outcomes of endovascular thrombectomy (EVT) for acute basilar artery occlusion (BAO) using population‐level data from the United States.MethodsWeighted discharge data from the National Inpatient Sample were queried to identify adult patients with acute BAO during the period of 2015 to 2019 treated with EVT or medical management only. Complex samples statistical methods and propensity‐score adjustment using inverse probability of treatment weighting (IPTW) were performed to assess clinical endpoints.ResultsAmong 3,950 BAO patients identified, 1,425 (36.1%) were treated with EVT [mean age 66.7 years, median National Institute of Health Stroke Scale (NIHSS) score 22]. On unadjusted analysis, 155 (10.9%) EVT patients achieved favorable functional outcomes (discharge disposition to home without services), while 515 (36.1%) experienced in‐hospital mortality, and 20 (1.4%) developed symptomatic intracranial hemorrhage (sICH). Following propensity‐score adjustment by IPTW accounting for age, stroke severity, and comorbidity burden, EVT was independently associated with favorable functional outcome [adjusted odds ratio (aOR) 1.25, 95% confidence interval (CI) 1.07, 1.46; p = 0.004], but not with in‐hospital mortality or sICH. In an IPTW‐adjusted sub‐group analysis of patients with NIHSS scores >20, EVT was associated with both favorable functional outcome (discharge disposition to home or to acute rehabilitation) (aOR 1.55, 95% CI 1.24, 1.94; p < 0.001) and decreased mortality (aOR 0.78, 95% CI 0.69, 0.89; p < 0.001), but not with sICH.InterpretationThis retrospective population‐based analysis using a large national registry provides real‐world evidence of a potential benefit of EVT in acute BAO patients.
