Published: October 2023

AbstractElectroreduction of nitrite to ammonia (NO2RR) holds great promise for concurrently achieving efficient NH3 electrosynthesis and wastewater purification. This study first develops Ni1Ru single‐atom alloys as an efficient and robust NO2RR catalyst. Extensive experiments and theoretical computations reveal that isolated Ni atoms electronically couple their adjacent Ru atoms to render Ni1Ru with high thermodynamic stability, boosted NO2−‐to‐NH3 hydrogenation energetics and suppressed hydrogen evolution. As a result, Ni1Ru assembled in a flow cell shows an exceptional NH3 yield rate of 37.5 mg h−1 cm−2 with an NH3‐Faradaic efficiency of 93.9% at a high current density of 312.3 mA cm−2, representing one of the highest NO2RR performances ever reported.

Published: October 2023

AbstractLipid‐based nanoparticles (LBNPs) are currently the most promising vehicles for nucleic acid drug (NAD) delivery. Although their clinical applications have achieved success, the NAD delivery efficiency and safety are still unsatisfactory, which are, to a large extent, due to the existence of multi‐level physiological barriers in vivo. It is important to elucidate the interactions between these barriers and LBNPs, which will guide more rational design of efficient NAD vehicles with low adverse effects and facilitate broader applications of nucleic acid therapeutics. This review describes the obstacles and challenges of biological barriers to NAD delivery at systemic, organ, sub‐organ, cellular, and subcellular levels. The strategies to overcome these barriers are comprehensively reviewed, mainly including physically/chemically engineering LBNPs and directly modifying physiological barriers by auxiliary treatments. Then the potentials and challenges for successful translation of these preclinical studies into the clinic are discussed. In the end, a forward look at the strategies on manipulating protein corona (PC) is addressed, which may pull off the trick of overcoming those physiological barriers and significantly improve the efficacy and safety of LBNP‐based NADs delivery.

Published: October 2023

AbstractTin perovskites have emerged as a promising alternative material to address the toxicity of lead perovskites and the low bandgap of around 1.1 eV is also compatible with tandem solar cell applications. Nevertheless, the optoelectronic performance of solution‐processed tin perovskite single‐crystal counterparts still lags behind because of the tin instability under ambient conditions during crystal growth and limited reductants to protect the Sn2+ ions from oxidation. Here, the reductant engineering to grow high‐quality tin perovskite single crystals under ambient conditions is studied. Oxalic acid (H2C2O4) serves as an excellent reductant and sacrificial agent to protect Sn2+ ions in methanol due to its suitable redox potential of −0.49 V, and the CO2 as the oxidation product in the gas state can be easily separated from the solution. The FPEA2SnI4 single crystal grown by this strategy exhibits low trap density perovskite surface by constructing an FPEA2PbI4‐FPEA2SnI4 (FPI‐FSI) single crystal heterojunction for X‐ray detection. An improved X‐ray sensitivity of 1.7 × 105 µC Gy−1 cm−2 is realized in the heterojunction device, outperforming the control FPEA2PbI4 counterpart.

Abstract3D ceramic architectures are captivating geometrical features with an immense demand in optics. In this work, an additive manufacturing (AM) approach for printing alkaline‐earth perovskite 3D microarchitectures is developed. The approach enables custom‐made photoresists suited for two‐photon lithography, permitting the production of alkaline‐earth perovskite (BaZrO3, CaZrO3, and SrZrO3) 3D structures shaped in the form of octet‐truss lattices, gyroids, or inspired architectures like sodalite zeolite, and C60 buckyballs with micrometric and nanometric feature sizes. Alkaline‐earth perovskite morphological, structural, and chemical characteristics are studied. The optical properties of such perovskite architectures are investigated using cathodoluminescence and wide‐field photoluminescence emission to estimate the lifetime rate and defects in BaZrO3, CaZrO3, and SrZrO3. From a broad perspective, this AM methodology facilitates the production of 3D‐structured mixed oxides. These findings are the first steps toward dimensionally refined high‐refractive‐index ceramics for micro‐optics and other terrains like (photo/electro)catalysis.

AbstractRealizing efficient red/near‐infrared (NIR) electroluminescence (EL) by precisely modulating molecular aggregations of thermally activated delayed fluorescence (TADF) emitters is an attractive pathway, yet the molecular designs are elusive. Here, a new approach is proposed to manage molecular aggregation via a mild‐twist acceptor‐donor‐acceptor (A‐D‐A)‐type molecular design. A proof‐of‐concept TADF molecule, QCN‐PhSAC‐QCN, is developed that furnishes a fast radiative rate and obvious aggregation‐induced emission feature. Its emission bands can be facilely shifted from intrinsic yellow to the red/NIR region via fine‐tuning doping levels and molecular aggregates while maintaining elegant photoluminescence quantum yields benefiting from suppressed exciton annihilation processes. As a result, a QCN‐PhSAC‐QCN‐based organic light‐emitting diode (OLED) exhibits a record‐setting external quantum efficiency (EQE) of 39.1% at a doping ratio of 10 wt.%, peaking at 620 nm. Moreover, its nondoped NIR OLED affords a champion EQE of 14.3% at 711 nm and retains outstanding EQEs of 5.40% and 2.35% at current densities of 10 and 100 mA cm−2, respectively, which are the highest values among all NIR‐TADF OLEDs at similar density levels. This work validates the feasibility of such mild‐twist A‐D‐A‐type molecular design for precisely controlling molecular aggregation while maintaining high efficiency, thus providing a promising pathway for high‐performance red/NIR TADF OLEDs.

Published: October 2023

AbstractOriginating from the intrinsic metallic and liquid natures, gallium‐based liquid metals (Ga‐based LMs) have been greatly developed in the research of soft electronics, chemical synthesis, and other fields due to their fascinating characteristics. Meanwhile, the development and application of metal optics can help modern medicine and industry reach rapid developmental stages, such as disease imaging, photothermal treatment, and sensor detection. However, Ga‐based LMs have been much less explored in terms of their optical properties, particularly liquid alloys, and few reviews have contributed to their photonic applications. Ga‐based LMs can achieve wideband‐tunable plasmonic resonance and exhibit characteristic optical responses owing to their unique polymorphisms, undercooling, and superior mobility. Ga‐based LMs have broad applications in optical switches and memory, optical sensors, light sources, light‐driven micro or nano‐robots, photoacoustic imaging, and controllable metamaterials. In this study, recent progress in the optical properties of Ga‐based LMs and their potential applications are summarized. Current challenges in optical applications and future perspectives in this research field are summarized and discussed.

Published: October 2023

AbstractReconfigurable metasurfaces have attracted widespread attention owing to their dynamic, multifunctional, and intelligent manipulation ability of electromagnetic waves. However, most previous reconfigurable meta‐devices work in one‐dimension (1D) due to the complex electrical wires and control circuits for two‐dimensional (2D) modulation. Here, an active matrix circuit composed of a MOSFET chip and a storage capacitor is introduced into the meta‐atom design to realize 2D control of reconfigurable metasurfaces. The number of the control circuits is reduced from M × N to M + N by applying sequential voltage and selecting the row/column. As proof of the scheme, a 10 × 10 active matrix integrated reconfigurable metasurface operating in X‐band is experimentally demonstrated. 2D beam scanning and point focusing with focal lengths of 60 mm & 120 mm are verified through 2D phase modulation. The scheme for 2D modulation has great potential in the construction of high‐frequency large‐scale compact reconfigurable metasurfaces and promises unprecedented progress for wireless telecommunication and microwave detection.

Authors: Yamamoto Yoshihiko 
Published: October 2023

AbstractTrifluoromethylated alkenes and alkynes are versatile building blocks for organofluorine synthesis. In addition, (trifluoromethyl)alkene motifs are found in biofunctional molecules. Hence, their synthesis is an important research objective. Although trifluoromethylated alkenes and alkynes have been prepared using transition‐metal‐mediated coupling reactions, more environmentally benign processes that obviate the use of precious metal catalysts and/or harsh reaction conditions should be developed. This review outlines recent advances in the synthesis of fluoroalkylated alkenes and alkynes via fluoroalkyl radical substitution reactions.

Authors: Akromah Stefania , Chandarana Neha , Eichhorn Stephen J. 
Published: October 2023

AbstractThe socio‐economic struggles in Africa are partly attributed to the low productivity of the agricultural sector. The Sustainable Development Goals Centre for Africa (SDGC/A) and the African Development Bank Group (AfDBG) both agree that the continent needs sustainable interventions to boost agricultural productivity, employment, and income. In this regard, mycelium composite production can present one potential solution. The added value to agricultural waste used to produce mycelium composites can generate additional revenue for farmers, serving as an incentive to increase agricultural productivity. Furthermore, the establishment of mycelium composite start‐ups can increase employment and income, especially for women and the youth. Mycelium composites can also aid in mitigating environmental and health challenges caused by some of the current waste management practices in Africa. This review offers valuable insights into the potential use of mycelium composites as a sustainable alternative for Africa. It explores the potential use of locally accessible resources, the potential applications for the composites in Africa, and the potential challenges that may arise with this technology. It further assesses the potential contribution of this technology to sustainable development in Africa in line with the Sustainable Development Goals (SDGs) set by the United Nations (UN).
Construction of Dual S‐Scheme Heterojunction Based Co9S8 QDs Coupling with NiS/CdS Concave Cubic Derived from Prussian Blue Analog for Enhanced Photocatalytic Hydrogen Evolution

Published: October 2023

AbstractThe design and development of high‐efficiency and low‐energy consumption catalysts for hydrogen evolution are critical to mitigating environmental problems. Herein, amorphous Co9S8 quantum dots (QDs) are prepared by hydrothermal method and loaded on concave cubic NiS/CdS derived from Prussian blue analog (PBA) to construct an efficient Co9S8 QDs/NiS/CdS dual S‐scheme heterojunction photocatalysts, showing excellent photocatalytic hydrogen performance of 13.45 mmol·g−1·h−1, which is 5.42 times higher than that of pure CdS. The improved photocatalytic performance is ascribed to the creation of a double S‐scheme heterojunction, quantum confinement effect, and a concave cubic structure, accelerating electron transport and offering ample surface active sites. The possible mechanism is demonstrated with valence band XPS (VB‐XPS), ultraviolet photoelectron spectroscopy (UPS), and density functional theory (DFT) calculations. This work provides insight into the exploration of PBA‐based photocatalysts to improve photocatalytic hydrogen evolution and provides an effective strategy for the design of photocatalysts with double the S‐scheme heterojunction.

AbstractThe reaction processes in Li‐ion batteries can be highly heterogeneous at the electrode scale, leading to local deviations in the lithium content or local degradation phenomena. To access the distribution of lithiated phases throughout a high energy density silicon‐graphite composite anode, correlative operando SAXS and WAXS tomography are applied. In‐plane and out‐of‐plane inhomogeneities are resolved during cycling at moderate rates, as well as during relaxation steps performed at open circuit voltage at given states of charge. Lithium concentration gradients in the silicon phase are formed during cycling, with regions close to the current collector being less lithiated when charging. In relaxing conditions, the multi‐phase and multi‐scale heterogeneities vanish to equilibrate the chemical potential. In particular, Li‐poor silicon regions pump lithium ions from both lithiated graphite and Li‐rich silicon regions. This charge redistribution between active materials is governed by distinct potential homogenization throughout the electrode and hysteretic behaviors. Such intrinsic concentration gradients and out‐of‐equilibrium charge dynamics, which depend on electrode and cell state of charge, must be considered to model the durability of high capacity Li‐ion batteries.

AbstractDeveloping electrode materials with high tap density, low cost, and superior performance poses a formidable challenge in electrochemistry. The impressive performance exhibited by most electrodes comes at the expense of tap density and cost, severely limiting their practical applications. Here, combining computational and experimental results, an approach for the electrode materials with high tap density and rich heterostructure (Cu2S/Na2Sn) from cheap copper smelting slag enabled by an electrochemical process is proposed, reducing the diffusion energy barrier from 0.82 to 0.28 eV for Na+, as well as delivering an impressively high tap density of 3.32 g cm−3. Furthermore, the electrochemical activation process that irreversibly generates more stable Cu2S and Na2Sn after the first charge progress of parent materials is also revealed by in/ex situ analytical techniques. As expected, assembled sodium ion capacitors (SICs) achieve high energy density (74.4 Wh kg−1) at high power density (20 000 W kg−1) with outstanding capacity retention of 81.5% after 10 000 cycles, delivering over 76% of its energy density in 13.4 s, which surpasses the performance achieved by state‐of‐the‐art SICs. This work not only provides novel insights into irreversibly conversion‐type anodes but also introduces a method for efficient value‐added utilization of smelting slag.

AbstractLithium nitrate is an attractive lithium additive in the construction of high‐performance lithium metal anodes with a Li3N‐rich solid electrolyte interphase (SEI) layer. However, the eight‐electron transfer process induces high energy barriers between LiNO3 and Li3N. Herein, the inner Helmholtz plane is tuned on a Li deposition host to attain sluggish/rapid LiNO3 decomposition kinetics, resulting in different intermediate content distributions of Li species in the SEI. Notably, lithium oxynitride (LiNO) is identified as the decomposition intermediate, and experimental and simulation results confirm its role in obstructing LiNO3 decomposition. Moreover, the results reveal that the dipole–dipole interaction between LiNO and the polar V≡N bond can change the ionic/covalent character of the N═O bonds, considerably facilitating the energy transfer process of the N═O cleavage, and promoting a LiNO3 reduction to achieve a Li3N‐rich SEI. Consequently, when the electrolyte contains 0.37 m LiNO3, dendrite, and dead Li formation are suppressed effectively with the VN system, and an average Coulombic efficiency of 99.7% over 1000 cycles (1 mA cm−2, 1 mAh cm−2) can be attained. These results can promote the nitride oxidation break process and pave the way for fabricating high‐performance Li3N‐rich lithium metal batteries.

Published: October 2023

AbstractPet‐food industry growth and demand for specialized product offerings have generated new opportunities for companies to enhance their competitiveness and profitability through effective product differentiation. Recent rise in e‐commerce and technological advancements for capturing and analyzing online customer review data provide new opportunities for large‐scale assessment of customer perceptions of product attributes. This paper presents an integrated qualitative and quantitative approach for utilizing online customer review data to generate insights for informing pet‐food industry product and marketing decisions. The results from the analysis of 5632 online reviews of two pet‐food products highlight (i) product attributes that effectively differentiate (or put on par) two competing pet‐food products, (ii) identify product attributes that are most important for customer postpurchase experience, and (iii) estimate the effect of specific attributes on customers' positive (or negative) postpurchase experience. Specific pet‐food attributes examined include packaging, health/benefit, ingredient, taste, smell, appearance/form, natural/organic, processing, sourcing, small/large breed, price, and service. The advantages of this approach include its ability to leverage large amounts of easily accessible data and its generalizability to the analysis of other consumer goods that have significant online sales and customer review data [EconLit Citations: Q13, M31].

AbstractLow‐count monoclonal B‐cell lymphocytosis (MBLlo) has been associated with an underlying immunodeficiency and has recently emerged as a new risk factor for severe COVID‐19. Here, we investigated the kinetics of immune cell and antibody responses in blood during COVID‐19 of MBLlo versus non‐MBL patients. For this study, we analyzed the kinetics of immune cells in blood of 336 COVID‐19 patients (74 MBLlo and 262 non‐MBL), who had not been vaccinated against SARS‐CoV‐2, over a period of 43 weeks since the onset of infection, using high‐sensitivity flow cytometry. Plasma levels of anti‐SARS‐CoV‐2 antibodies were measured in parallel by ELISA. Overall, early after the onset of symptoms, MBLlo COVID‐19 patients showed increased neutrophil, monocyte, and particularly, plasma cell (PC) counts, whereas eosinophil, dendritic cell, basophil, and lymphocyte counts were markedly decreased in blood of a variable percentage of samples, and with a tendency toward normal levels from week +5 of infection onward. Compared with non‐MBL patients, MBLlo COVID‐19 patients presented higher neutrophil counts, together with decreased pre‐GC B‐cell, dendritic cell, and innate‐like T‐cell counts. Higher PC levels, together with a delayed PC peak and greater plasma levels of anti‐SARS‐CoV‐2‐specific antibodies (at week +2 to week +4) were also observed in MBLlo patients. In summary, MBLlo COVID‐19 patients share immune profiles previously described for patients with severe SARS‐CoV‐2 infection, associated with a delayed but more pronounced PC and antibody humoral response once compared with non‐MBL patients.

AbstractObjectivesThis brief communication documents the prevalence of maxillary central incisor talon cusps in Cayo Santiago rhesus monkeys (Macaca mulatta) and assesses whether talon cusp presence occurs at equivalent frequencies across matrilines.Materials and MethodsThe data on cusp presence vs. absence were analyzed by logistic regression in 170 monkeys (82 females, 78 males) from seven different matrilines. Sample sizes per matriline ranged from 10 to 42. Observations of talon cusps were blind with respect to matriline and sex.ResultsTalon cusps were present in 9.4% of the sample. By matriline, cusp frequencies ranged from 0%—Matrilines 073 and 106%—to 19.1% in Matriline 076. The frequency of the talon cusp in Matriline 076 was significantly greater than the frequency of the cusp in the remainder of the sample. There was no statistically significant difference in the frequency of the talon cusp by sex.ConclusionsThis study suggests that the talon cusp in rhesus monkeys, as in humans and baboons, is a rare trait. Elevated prevalence of the talon cusp in Matriline 076 suggests the possibility of a genetic influence on talon cusp expression.
