AbstractMicrocapsules with a liquid core and a solid shell composed of hydrophobic nanoparticles are broadly applied in food, pharmaceutics, and biotechnologies. For example, Pickering emulsions, colloidosomes, or antibubbles (droplets surrounded by air layers in water) enable controlled release of active agents, biocompatibility, and contact‐less liquid transportation. However, producing controlled nanoparticle‐ or polymer‐laden hydrophobic shells at scale is highly challenging, since bulk methods are polydisperse and microfluidic chips are prone to clogging and slow. Here, clog‐free coating of an aqueous jet with silica nanoparticle suspensions with concentrations up to 10% (w/v), as well as high concentrations of polymers (30% (w/v) poly(lactic acid) (PLA)), is demonstrated, enabling continuous generation of microcapsules at flow rates up to 4 mL min−1. Pickering emulsions are converted into capsules, providing hydrophobic shells consisting of nanoparticles for controlled release. As a highlight, the scalable fabrication of air‐coated capsules (antibubbles) in the sub‐millimeter range is demonstrated. The shell contains an air film that protects the liquid core for days yet enables ultrasound‐induced release within 3 min. By enabling rapid fabrication of controlled Pickering emulsions, colloidosomes, antibubbles, and biodegradable capsules, jetting through a liquid layer (JetALL) provides a versatile platform for advanced applications in food, pharmacy, and life science.

AbstractCO2 electroreduction is of great significance to reduce CO2 emissions and complete the carbon cycle. However, the unavoidable carbonate formation and low CO2 utilization efficiency in neutral or alkaline electrolytes hinder its application at commercial scale. The development of CO2 reduction under acidic conditions provides a promising strategy, but the inhibition of the hydrogen evolution reaction is difficult. Herein, the first work to design a Ni–Cu dual atom catalyst supported on hollow nitrogen‐doped carbon is reported for pH‐universal CO2 electroreduction to CO. The catalyst shows a high CO Faradaic efficiency of ≈99% in acidic, neutral, and alkaline electrolytes, and the partial current densities of CO reach 190 ± 11, 225 ± 10, and 489 ± 14 mA cm−2, respectively. In particular, the CO2 utilization efficiency under acidic conditions reaches 64.3%, which is twice as high as that of alkaline conditions. Detailed study indicates the existence of electronic interaction between Ni and Cu atoms. The Cu atoms push the Ni d‐band center further toward the Fermi level, thereby accelerating the formation of *COOH. In addition, operando characterizations and density functional theory calculation are used to elucidate the possible reaction mechanism of CO2 to CO under acidic and alkaline electrolytes.

AbstractThe sluggish ionic transport in thick electrodes and freezing electrolytes has limited electrochemical energy storage devices in lots of harsh environments for practical applications. Here, a 3D‐printed proton pseudocapacitor based on high‐mass‐loading 3D‐printed WO3 anodes, Prussian blue analog cathodes, and anti‐freezing electrolytes is developed, which can achieve state‐of‐the‐art electrochemical performance at low temperatures. Benefiting from the cross‐scale 3D electrode structure using a 3D printing direct ink writing technique, the 3D‐printed cathode realizes an ultrahigh areal capacitance of 7.39 F cm−2 at a high areal mass loading of 23.51 mg cm−2. Moreover, the 3D‐printed pseudocapacitor delivers an areal capacitance of 3.44 F cm−2 and excellent areal energy density (1.08 mWh cm−2). Owing to the fast ion kinetics in 3D electrodes and the high ionic conductivity of the hybrid electrolyte, the 3D‐printed supercapacitor delivers 61.3% of the room‐temperature capacitance even at −60 °C. This work provides an effective strategy for the practical applications of energy storage devices with complex physical structure at extreme temperatures.

Published: January 2023

AbstractMaterials derived from metal–organic frameworks (MOFs) have demonstrated exceptional structural variety and complexity and can be synthesized using low‐cost scalable methods. Although the inherent instability and low electrical conductivity of MOFs are largely responsible for their low uptake for catalysis and energy storage, a superior alternative is MOF‐derived metal‐based derivatives (MDs) as these can retain the complex nanostructures of MOFs while exhibiting stability and electrical conductivities of several orders of magnitude higher. The present work comprehensively reviews MDs in terms of synthesis and their nanostructural design, including oxides, sulfides, phosphides, nitrides, carbides, transition metals, and other minor species. The focal point of the approach is the identification and rationalization of the design parameters that lead to the generation of optimal compositions, structures, nanostructures, and resultant performance parameters. The aim of this approach is to provide an inclusive platform for the strategies to design and process these materials for specific applications. This work is complemented by detailed figures that both summarize the design and processing approaches that have been reported and indicate potential trajectories for development. The work is also supported by comprehensive and up‐to‐date tabular coverage of the reported studies.

Published: January 2023

AbstractInterfacial defects result in serious carrier nonradiative recombination. The correlation between spatial conformation of modifiers and interfacial carrier dynamics is scarcely revealed. Here, an effective interfacial carrier dynamics and defect passivation modulation strategy via controlling spatial conformation of modification molecules is reported. Two kinds of similar Lewis base ligand molecules, biuret (BU) and dithiobiuret (DTBU), are employed to modify the surface of perovskite films. BU and DTBU can effectively passivate interfacial defects but the former is more effective than the latter on account of higher electronegativity and more advantageous molecular spatial arrangement. The planar symmetrical BU molecules can arrange compactly and orderly on the surface of perovskite films while the adsorbed DTBU molecules with a twisted asymmetrical structure are relatively chaotic. BU modification reduces interfacial energy offset, ameliorates improved interfacial energy band alignment, and speeds up hole extraction. In contrast, a much thicker adsorbed layer is yielded after DTBU treatment, which impedes carrier extraction and transfer and accordingly leads to grievous nonradiative recombination. The spatial conformation difference produces an inverse influence on device performance (positive for BU and negative for DTBU). The power conversion efficiency is much enhanced from 21.66% to 23.54% after BU modification along with improved stability.

AbstractStructural colors based on dielectric metasurfaces are attractive because of their potential application in next‐generation color printing. However, the commonly used dielectric materials suffer from issues of high light absorption (e.g., Si at blue wavelength) and low resistance to corrosion (e.g., titanium oxide), which greatly limit their application as structural color for information encryption. Here, dielectric‐metasurface‐based structural color constructed on nanocrystalline diamond (NCD) film by using bias enhanced nucleation (BEN) technique is demonstrated. Owing to the formation of highly crystalline diamond by the BEN process, the synthesized NCD film with a thickness of ~500 nm exhibits excellent optical quality with a relatively high refractive index that produces a strong magnetic dipole mode by Mie resonance. To realize the dynamic functionalities of diamond‐metasurface color with high resolution, a periodic array of asymmetric diamond cuboids with high aspect ratio (≈3.1) is fabricated, which produces polarization‐dependent response due to the enhanced Mie resonance. By optimizing the configuration of the diamond‐metasurface system, the color performance is improved with high brightness and a relatively wide gamut. This work demonstrates for the first time that NCD can serve as a robust and highly tunable dielectric platform for application in information encryption.

AbstractEnvironmental and health risks posed by microplastics (MPs) have spurred numerous studies to better understand MPs' properties and behavior. Yet, we still lack a comprehensive understanding due to MP's heterogeneity in properties and complexity of plastic property evolution during aging processes. There is an urgent need to thoroughly understand the properties and behavior of MPs as there is increasing evidence of MPs' adverse health and environmental effects. In this perspective, we propose an integrated chemical engineering approach to improve our understanding of MPs. The approach merges artificial intelligence, theoretical methods, and experimental techniques to integrate existing data into models of MPs, investigate unknown features of MPs, and identify future areas of research. The breadth of chemical engineering, which spans biological, computational, and materials sciences, makes it well‐suited to comprehensively characterize MPs. Ultimately, this perspective charts a path for cross‐disciplinary collaborative research in chemical engineering to address the issue of MP pollution.

Published: January 2023

AbstractTwo‐dimensional (2D) monoelemental materials (Xenes) show considerable potential in bioapplications owing to their unique 2D physicochemical features and the favored biosafety resulting from their monoelemental composition. However, the narrow band gaps of Xenes prevent their broad applications in biosensors, bioimaging and phototherapeutics. In this study, it is demonstrated that 2D germanene terminated with −H via surface chemical engineering, shows a much broadened direct band gap of 1.65 eV, which enables the material to be used as a novel inorganic photosensitizer for the photodynamic therapy of singlet oxygen. Through theoretical analysis and in vitro studies, H‐germanene nanosheets demonstrate a substantially enlarged band gap and favorable biodegradability, demonstrating a substantial cancer treatment capacity. This study demonstrates the feasibility of constructing novel therapeutic photodynamic agents by surface covalent engineering for catalytic tumor therapy.

Published: January 2023

AbstractGas separation efficiency of covalent organic framework (COF) membrane can be greatly elevated through precise functionalization. A pair‐functionalized COF membrane of 1,3,5‐triformylphloroglucinol (TP) and isoquinoline‐5,8‐diamine (IQD) monomers in two and three nodes is designed and synthesized. TP‐IQD is crystallized in a two‐dimensional structure with a pore size of 6.5 Å and a surface area of 289 m2 g−1. This COF possesses N−O paired groups which cooperatively interact with C2H2 instead of C2H4. TP‐IQD nanosheets of ≈10 μm in width and ≈4 nm in thickness are prepared by mechanical exfoliation; they are further processed with 6FDA‐ODA polymer into a hybrid membrane. High porosity and functionality pair of TP‐IQD offer the membrane with significantly increased C2H2 permeability and C2H2/C2H4 selectivity which are 160 % and 430 % higher of pure 6FDA‐ODA. The boosted performance demonstrates high efficiency of the pair‐functionality strategy for the synthesis of separation‐led COFs.

Published: January 2023

AbstractWe report phosphinidenes (PR) stabilized by an intramolecular frustrated Lewis pair (FLP) chelate. These adducts include the parent phosphinidene, PH, which is accessed via thermolysis of coordinated HPCO. The reported FLP‐PH species acts as a springboard to other phosphorus‐containing compounds, such as FLP‐adducts of diphosphorus (P2) and InP3. Our new adducts participate in thermal‐ or light‐induced phosphinidene elimination (of both PH and PR, R=organic group), transfer P2units to an organic substrate, and yield the useful semiconductor InP at only 110 °C from solution.
A machine learning model and biometric transformations to facilitate European oyster monitoring

Published: January 2023

Abstract

Ecosystem monitoring, especially in the context of marine conservation and management requires abundance and biomass metrics, condition indices, and measures of ecosystem services of key species, all of which can be calculated using biometric transformation factors.
Following ecosystem restoration measures in the North Sea and north‐east Atlantic waters, European oyster (Ostrea edulis) restoration and its monitoring have substantially increased over the past decade. Restoration activities are implemented by diverse approaches and practitioners ranging from governmental conservation agencies, research institutions and non‐governmental institutions to regional groups, including citizen science projects. Thus, tools for facilitating data acquisition and estimation with non‐destructive techniques can support monitoring quantitatively and qualitatively.
Weight‐to‐weight transformation factors for calculating dry weight of O. edulis from wet weight measurements are presented. Another important tool is the estimation of weight only from size measurements. The classical approach to achieve these transformation factors is the construction of allometric models, which, however, can greatly vary among regions and between years, making them extremely location/season specific.
Alternative and more flexible models constructed using random forests are proposed. This algorithm is a machine learning technique that is increasingly used in ecology, and has been proven to outperform other predictive models. From biometric variable measurements of 1,401 O. edulis individuals, allometric models were used to estimate total, shell and body wet weights, and compare them with 15 random forest models.
In general, the random forest models outperformed the allometric ones, with lower error when estimating weight. The developed random forest models can thus provide a tool for facilitating oyster restoration monitoring by increasing data acquisition without the need of sacrificing European oyster individuals. Their improvement can imply its implementation in other regions and support European oyster restoration and monitoring efforts throughout Europe.

AbstractIntroductionEssential oil inhalation has various effects on the human body. However, its effects on cognitive function and the neural basis remain unclear. We aimed to investigate the effects of inhaling lemon, sandalwood, and kusunoki essential oils on human brain activity and memory function using multichannel electroencephalography and brain source activity estimation.MethodsParticipants performed a letter 2‐back working memory task during electroencephalography measurements before and after essential oil inhalation. Brain activation, task difficulty, concentration degree, and task performance were compared among the essential oils and a fragrance‐free control.ResultsTask performance significantly improved after lemon essential oil inhalation. Lemon essential oil inhalation resulted in delta and theta band activation in the prefrontal cortex, including the anterior cingulate gyrus and orbitofrontal cortex, superior temporal gyrus, parahippocampal gyrus, and insula. During inhalation, persistent alpha band activation was observed in the prefrontal cortex, including the anterior cingulate gyrus. Sandalwood essential oil inhalation led to beta and gamma band activation in the prefrontal cortex, including the anterior cingulate gyrus.ConclusionOur findings demonstrate that different essential oils have specific effects on brain activity related to emotion and memory processing.

Published: January 2023

AbstractPhosphites are industrially important ligands for the Rh‐catalysed hydroformylation of olefins because they produce more active catalysts than phosphines, which is mainly due to their strong π‐acceptor properties facilitating CO dissociation from the metal centre. Herein, the effect of three prominent phosphite ligands (triphenylphosphite, Alkanox and BiPhePhos) on catalyst speciation during turnover is investigated using multi‐nuclear operando FlowNMR spectroscopy. The quantitative catalyst distribution maps derived explain activity trends across a range of catalytic reaction conditions that show how phosphites produce more active catalysts, including reduced formation of inactive Rh0 dimers in the absence of substrate during pre‐activation and at the end of the reaction. Additionally, [(alkanox)Rh(acac)] complexes have been found to be of high stability which can be exploited for post‐catalytic Rh recovery by simple addition of 2,4‐pentanediones.

Authors: Canamas Pablo , Gozzi Nathan , Du Jiupeng , Guichardon Pierrette 
Published: January 2023

AbstractFor cosmetic industrial applications, polyurea microcapsules were formed by using hexamethylene diisocyanate biuret low viscosity (HDB‐LV) and three different amines: ethylenediamine (EDA), guanidine (GUA), and hexamethylenediamine (HMDA). Toluene droplets containing dissolved HDB‐LV were formed by an oil‐in‐water emulsion before being poured into a water phase containing the required excess of amine. The pH of the aqueous phase was fitted through time to calculate the kinetic constant k' and the diffusion constant DB through the polyurea shell when possible. At 60 °C, EDA and HMDA follow a pure kinetic regime, whereas GUA follows a combination of kinetic and diffusion regimes. The presented kinetic data shows that HDB‐LV is a promising nontoxic isocyanate for cosmetic encapsulation.

Published: January 2023

AbstractLindqvist polyoxovanadate‐alkoxide (POV‐alkoxide) clusters are excellent candidates for applications in energy storage and conversion due to their rich electrochemical profiles. One approach to tune the redox properties of these cluster complexes is through substitutional cationic doping within the hexavanadate core. Here, we report the synthesis of a series of tungsten‐substituted POV‐alkoxide clusters with one and two tungsten atoms. Soft landing of mass‐selected ions was used to purify heterometal POV‐alkoxides that cannot be readily separated using conventional approaches. The soft landed POV‐alkoxides are characterized using infrared reflection‐absorption spectroscopy and electrospray ionization mass spectrometry. The redox properties of the isolated ions are examined using an in situ electrochemical cell which enables traditional in vacuo electrochemical measurements inside of an ion soft landing instrument. Although the overall cluster core retains redox activity after tungsten doping, vanadium‐based redox couples (VV/VIV) are shifted substantially, indicating a pronounced effect of a heteroatom on the electronic structure of the core.
Hierarchical Porous Carbon Spheres Loaded CoOX (CoOx/HPCS) for Efficient Oxygen Reduction Reaction in Alkaline Media
Authors: Hua Yani , Shi Hongwei , Liu Jiamei , Gao Zhan 
Published: January 2023

AbstractThe development of efficient non‐noble metal catalysts for oxygen reduction reaction (ORR) in alkaline media is vital for wide application of numerous energy conversion devices. In this work, the CoOx/HPCS catalysts are demonstrated to show excellent activity toward ORR with more positive peak potential, initial potential, and half‐wave potential than pure HPCS. Moreover, the CoOx/HPCS exhibits a long‐term stability and a stronger methanol resistance compared to 20% Pt/C. The outstanding ORR activity for CoOx/HPCS is owing to its excellent characteristics, like: 1) a good conductivity of the carbon matrix to improve the electron transfer ability; 2) the rich hierarchical hollow carbon matrix and high surface area conducive to providing more accessible active sites and improving mass transportation; 3) the defect caused by oxygen vacancy beneficial for enhancing catalytic activity; 4) the synergistic effect between CoOx and HPCS support being crucial for ORR, thence enhancing the electrochemical performance of CoOx/HPCS.
