Hydro/Organo/Ionogels: “Controllable” Electromagnetic Wave Absorbers
Authors: Zhao Zehao , Zhang Limin , Wu Hongjing 
Published: September 2022

AbstractDemand for electromagnetic wave (EMW) absorbers continues to increase with technological advances in wearable electronics and military applications. In this study, a new strategy to overcome the drawbacks of current absorbers by employing the co‐contribution of functional polymer frameworks and liquids with strong EMW absorption properties is proposed. Strongly polar water, dimethyl sulfoxide/water mixtures, and highly conductive 1‐ethyl‐3‐methylimidazolium ethyl sulfate ([EMI][ES]) are immobilized in dielectrically inert polymer networks to form different classes of gels (hydrogels, organogels, and ionogels). These gels demonstrate a high correlation between their dielectric properties and polarity/ionic conductivity/non‐covalent interaction of immobilized liquids. Thus, the EMW absorption performances of the gels can be precisely tuned over a wide range due to the diversity and stability of the liquids. The prepared hydrogels show good shielding performance (shielding efficiency > 20 dB) due to the high dielectric constants, while organogels with moderate attenuation ability and impedance matching achieve full‐wave absorption in X‐band (8.2–12.4 GHz) at 2.5 ± 0.5 mm. The ionogels also offer a wide effective absorption bandwidth (10.79–16.38 GHz at 2.2 mm) via prominent ionic conduction loss. In short, this work provides a conceptually novel platform to develop high‐efficient, customizable, and low‐cost functional absorbers.

AbstractLi‐ion batteries have made inroads into the electric vehicle market with high energy densities, yet they still suffer from slow kinetics limited by the graphite anode. Here, electrolytes enabling extreme fast charging (XFC) of a microsized graphite anode without Li plating are designed. Comprehensive characterization and simulations on the diffusion of Li+ in the bulk electrolyte, charge‐transfer process, and the solid electrolyte interphase (SEI) demonstrate that high ionic conductivity, low desolvation energy of Li+, and protective SEI are essential for XFC. Based on the criterion, two fast‐charging electrolytes are designed: low‐voltage 1.8 m LiFSI in 1,3‐dioxolane (for LiFePO4||graphite cells) and high‐voltage 1.0 m LiPF6 in a mixture of 4‐fluoroethylene carbonate and acetonitrile (7:3 by vol) (for LiNi0.8Co0.1Mn0.1O2||graphite cells). The former electrolyte enables the graphite electrode to achieve 180 mAh g−1 at 50C (1C = 370 mAh g−1), which is 10 times higher than that of a conventional electrolyte. The latter electrolyte enables LiNi0.8Co0.1Mn0.1O2||graphite cells (2 mAh cm−2, N/P ratio = 1) to provide a record‐breaking reversible capacity of 170 mAh g−1 at 4C charge and 0.3C discharge. This work unveils the key mechanisms for XFC and provides instructive electrolyte design principles for practical fast‐charging LIBs with graphite anodes.

Published: September 2022

AbstractThe poor stability of the zinc‐metal anode is a main bottleneck for practical application of aqueous zinc‐ion batteries. Herein, a series of molecular sieves with various channel sizes are investigated as an electrolyte host to regulate the ionic environment of Zn2+ on the surface of the zinc anode and to realize separator‐free batteries. Based on the ZSM‐5 molecular sieve, a solid–liquid mixed electrolyte membrane is constructed to uniformize the transport of zinc ions and foster dendrite‐free Zn deposition. Side reactions can also be suppressed through tailoring the solvation sheath and restraining the activity of water molecules in electrolyte. A V2O5||ZSM‐5||Zn full cell shows significantly enhanced performance compared to cells using glass fiber separator. Specifically, it exhibits a high specific capacity of 300 mAh g−1, and a capacity retention of 98.67% after 1000 cycles and 82.67% after 3000 cycles at 1 A g−1. It is attested that zeolites (ZSM‐5, H‐β, and Bate) with channel sizes of 5–7 Å result in best cycle stability. Given the low cost and recyclability of the ZSM and its potent function, this work may further lower the cost and boost the industrial application of AZIBs.

Published: September 2022

AbstractThe functionality of ferroelastic domain walls in ferroelectric materials is explored in real‐time via the in situ implementation of computer vision algorithms in scanning probe microscopy (SPM) experiment. The robust deep convolutional neural network (DCNN) is implemented based on a deep residual learning framework (Res) and holistically nested edge detection (Hed), and ensembled to minimize the out‐of‐distribution drift effects. The DCNN is implemented for real‐time operations on SPM, converting the data stream into the semantically segmented image of domain walls and the corresponding uncertainty. Further the pre‐defined experimental workflows perform piezoresponse spectroscopy measurement on thus discovered domain walls, and alternating high‐ and low‐polarization dynamic (out‐of‐plane) ferroelastic domain walls in a PbTiO3 (PTO) thin film and high polarization dynamic (out‐of‐plane) at short ferroelastic walls (compared with long ferroelastic walls) in a lead zirconate titanate (PZT) thin film is reported. This work establishes the framework for real‐time DCNN analysis of data streams in scanning probe and other microscopies and highlights the role of out‐of‐distribution effects and strategies to ameliorate them in real time analytics.
Self‐Sustaining Fluorination of Active Methylene Compounds and High‐Yielding Fluorination of Highly Basic Aryl and Alkenyl Lithium Species with a Sterically Hindered N‐Fluorosulfonamide Reagent
Authors: Yang Yuhao , Hammond Gerald B. , Umemoto Teruo 
Published: September 2022

AbstractFluorination of carbanions is pivotal for the synthesis of fluorinated compounds, but the current N‐F fluorinating agents have significant drawbacks due to many reactive locations that surround the reactive N−F site. By developing a sterically hindered N‐fluorosulfonamide reagent, namely N‐fluoro‐N‐(tert‐butyl)‐tert‐butanesulfonamide (NFBB), we discovered a conceptually novel base‐catalyzed, self‐sustaining fluorination of active methylene compounds and achieved the high‐yielding fluorination of the hitherto difficult highly basic (hetero)aryl and alkenyl lithium species. In the former, the mild and high yield fluorination of active methylene compounds exhibited wide functional group tolerance and its novel catalytic fluorination‐deprotonation cycle mechanism was demonstrated by deuterium‐tracing experiments. In the latter, NFBB reacted with a variety of highly basic (hetero)aryl and alkenyl lithium species to provide the desired fluoro (hetero)arenes and alkenes in unprecedented high or quantitative yields.

AbstractCytochrome P450 monooxygenases (CYPs) are present in almost all areas of the tree of life. As one of the largest and most diverse superfamilies of multifunctional enzymes, they play important roles in the metabolism of xenobiotics and biosynthesis of endogenous compounds, shaping the success of insects. In this study, the CYPome (an omics term for all the CYP genes in a genome) diversification was examined in the four Tenebrionidea species through genome‐wide analysis. A total of 483 CYP genes were identified, of which 103, 157, 122, and 101 were respectively deciphered from the genomes ofTebebrio molitor,Asbolus verucosus,Hycleus cichoriiandHycleus phaleratus. These CYPs were classified into four major clans (mitochondrial, CYP2, CYP3, and CYP4), and clans CYP3 and CYP4 are most diverse. Phylogenetic analysis showed that most CYPs of these Tenebrionidea beetles from each clan had a very close 1:1 orthology to each other, suggesting that they originate closely and have evolutionally conserved function. Expression analysis at different developmental stages and in various tissues showed the life stage‐, gut‐, salivary gland‐, fat body‐, Malpighian tubule‐, antennae‐, ovary‐ and testis‐specific expression patterns ofT. molitorCYP genes, implying their various potential roles in development, detoxification, immune response, digestion, olfaction, and reproduction. Our studies provide a platform to understand the evolution of Tenebrionidea CYP gene superfamily, and a basis for further functional investigation of theT. molitorCYPs involved in various biological processes.

ObjectiveTo determine whether a single session of botulinum toxin type A (BTA) injections into both hands more effectively decreases the frequency of systemic sclerosis–associated Raynaud's phenomenon (SSc‐RP) episodes than placebo.MethodsThis multicenter, randomized, double‐blind, placebo‐controlled, parallel‐group phase III trial in patients with SSc‐RP assessed the effect of 50‐unit BTA or placebo injections into the palms of both hands around each neurovascular bundle during 1 session in winter. The primary end point was the between‐group difference in the median change in the number of RP episodes from baseline (day 0) to 4 weeks postinjection. Values between the groups were compared with the Wilcoxon rank‐sum test.ResultsThe intent‐to‐treat analysis included 46 BTA‐treated patients and 44 placebo recipients. At 4 weeks after assigned treatment injections, the median number of daily RP episodes decreased comparably in the BTA and placebo groups (median change –1 episode/day [interquartile range (IQR) –1.5, 0 episodes/day] and –1 episode/day [IQR –2.5, 0 episodes/day], respectively) (P = 0.77 versus placebo). Moreover, change in Raynaud's Condition Score, quality of life assessed by Health Assessment Questionnaire disability index, and hand function assessed by shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Cochin Hand Function Scale from baseline to follow‐up weeks 4, 12, and 24 did not differ significantly between groups. The BTA group experienced transient hand muscle weakness significantly more frequently (P = 0.003).ConclusionNeither the primary nor secondary end points were reached, and our results do not support any beneficial effect of palmar BTA injections to treat SSc‐RP.image

AbstractBismuth ion (Bi3+) sensitized, europium ion (Eu3+) activated La2Zr2O7 nanophosphors are prepared successfully by simple wet chemical method. Strong blue emission of singly doped La2Zr2O7 with Bi3+ was observed at 310 nm excitation, its wide emission spectrum has a peak maximum at 465 nm ascribed to electronic transition 3P1 → 1S0 of Bi3+. The recorded photoluminescence spectra of y at% Eu3+ codoped La2Zr2O7, when excited at 285 nm, the emission spectrum exhibits maximum peaks at wavelength values 615 nm, 646 nm and 665 nm which are ascribed to 5D0 → 7F2, 5D0 → 7F3 and 5D0 → 7F4 transitions of Eu3+ respectively. The chromaticity coordinates for the optimized sample were found to be (0.519, 0.329). Sensitizing with Bi3+ can affect the luminescence properties of La2Zr2O7:Eu3+ phosphors. With reference to the change in Eu3+ concentration from Y  = 1, 2, 3, 4 and 5%, color tunable luminescence from blue to orange, red of La2Zr2O7:Bi3+,Eu3+ phosphors are observed. The lifetime decay values, energy level description and CIE chromatic color coordinates for Bi3+, Eu3+ in La2Zr2O7:Bi3+,Eu3+ codoped sample was discussed. The spectral overlap between sensitizer, activator ions confirms the efficient energy transfer from Bi3+ to Eu3+ in La2Zr2O7:Bi3+,Eu3+ codoped sample and is via a dipole‐quadruple mechanism.

AbstractA sensitive, selective and rapid bioanalytical method using liquid chromatography–tandem mass spectrometry has been developed for the quantification of trifluoperazine in human plasma. Trifluoperazine‐D8 was used as the internal standard and the extraction from human plasma was performed by liquid–liquid extraction technique using tertiary butyl methyl ether as the solvent. Chromatographic separation was carried out on Zodiac C18 column (50 × 4.6 mm, 3 μm) employing a mixture of acetonitrile, methanol and 5 mm ammonium bicarbonate buffer in water (85:10:5, v/v/v) at a flow rate of 0.55 ml/min. The linearity was established within the concentration range of 5–1,250 pg/ml with r2 > 0.99. The results of all of the validation parameters as per the US Food and Drug Administration guidelines were within the acceptance limits. The pharmacokinetics of trifluoperazine after oral administration of a syrup of 1 mg dose under fasting conditions was determined by successful application of the present method.
Convergence towards a digitalized bioeconomy—Exploring cross‐industry merger and acquisition activities between the bioeconomy and the digital economy

Published: September 2022

AbstractGreat importance is attributed to a transition towards a bioeconomy regime. The bioeconomy can foster more sustainable production and consumption systems and therefore contribute to the achievement of the United Nations Sustainable Development Goals. This transition is facing several inhibitors, such as dysfunctional communication between different actors and insufficient innovative activity. Scholars and practitioners consider coupling technological developments between the bioeconomy and the digital economy as a driving‐force to accelerate the transition towards a bioeconomy and bring solutions to major inhibitors. In this paper, we therefore seek to better understand how and if the bioeconomy and the digital economy converge to create the needed momentum and capture the full potential. Whereas the increasing number of scientific papers highlight benefits of digital technologies for the bioeconomy, our analyses of merger and acquisitions reveal tendencies of an initial blurring of boundaries between both, bioeconomy and digital economy market boundaries. Still, bioeconomy companies acquire digital companies to a greater extend indicating high benefit of implementing digital technologies within the bioeconomy. Our results contribute to the extant body of convergence research by implementing convergence indicators in a new case study as well as coupling transition theory and convergence literature. Both literature bodies support the better understanding of the transition towards a knowledge‐based digital economy as transition theory describes the path to a new digital bioeconomy regime created by cross‐sectoral convergence.

AbstractThe worldwide increased consumption of goods and services squeezes natural resources, thus causing severe damage to the environment. In the backdrop of the growing affirmative reaction of people, the inclination to buy green products is on the rise. Therefore, we explore the extant literature to identify the factors established for their role in determining the purchase of products having a less damaging impact on the environment. A systematic literature review was conducted following the Theory‐Context‐Characteristics‐Methodology framework covering 151 empirical studies on green purchase intention and green purchase behavior, published between years 2000 and 2021. This paper identifies factors influencing consumers' green purchase intention and green purchase behavior and provides strategic insights to marketers to create better marketing opportunities for green products.

Published: September 2022

AbstractDeveloping high‐efficiency electrocatalysts for oxygen evolution reaction (OER) based on non‐precious transition metal materials alternative to noble metal has remained a great challenge in electrochemical water splitting. Meanwhile, the use of clean and sustainable solar energy is also crucial for renewable energy storage. Herein, a novel photo‐responsive electrocatalyst with proper energy band type, i. e., n type CoS2 semiconductor decorated on p‐type Co3O4 nanorod (Co3O4/CoS2), is prepared via a simple two‐step hydrothermal process. Consequently, the Co3O4/CoS2 shows small overpotential of 255 mV for OER to afford current density of 10 mA cm−2 after illumination, which is 40 mV lower than that without illumination. It also presents high electrochemically active surface areas and good stability. This significantly enhanced electrocatalytic OER performance is attributable to increased oxygen vacancies and highly active Co−S species that are electrooxidized to active site (Co3+) during OER. This work provides an effective perspective for the development of high efficiency OER catalysts based on non‐noble metals combined with solar energy as a renewable energy source.

Published: September 2022

AbstractThe electrochemical synthesis of fluorinated allyl silanes and boronates was disclosed. The addition of electrogenerated boryl or silyl radicals onto many α‐trifluoromethyl or α‐difluoromethylstyrenes in an undivided cell allowed the formation of a large panel of synthetically useful gem‐difluoro and γ‐fluoroallyl boronates and silanes (64 examples, from 31 % to 95 % yield). In addition, a scale up of the reactions under continuous flow was showcased using an electrochemical reactor with promising volumetric productivity (688 g.L−1.h−1 and 496 g.L−1.h−1). Moreover, the synthetic utility of these building blocks was highlighted through versatile transformations. Finally, plausible reaction mechanisms were suggested to explain the formation of the products.

Published: September 2022

AbstractChiral macrocyclic dimers, trimers, and tetramers composed of paraphenylene and tethered binaphthyl were synthesized, and their molecular structures and chiroptical properties were investigated. X‐ray analysis and theoretical calculations revealed that multiple twisted molecular structures – dimers, trimers, and tetramers – adopt figure‐of‐eight, Möbius triangle, and concave rectangle structures, respectively. These homologues have largeϵvalues in their UV‐vis absorption spectra because of the π‐conjugation of the naphthalene‐phenylene‐naphthalene frameworks. Owing to the shape‐persistent ring structure and tethering with −OCH2CH2O−, high fluorescence quantum yields and a relatively high dissymmetry factorgCPLin circularly polarized luminescence (CPL) spectra were achieved. This results in CPL brightness (BCPL) of over 100, which is greater than that of the conventional organic CPL dye.

Published: September 2022

AbstractIn recent years, intermetallic nanocrystals (IMNCs) have attracted extensive attention in the field of electrocatalysis. However, precise control over the size, shape, composition, structure, and exposed crystal facet of IMNCs seems to be a challenge to the traditional method of high‐temperature annealing although these parameters have a significant effect on the electrocatalytic performance. Controllable synthesis of IMNCs by the wet chemistry method in the liquid phase shows great potential compared with the traditional high‐temperature annealing method. In this Review, we attempt to summarize the preparation of IMNCs by the seed‐mediated synthesis in the liquid phase, as well as their applications in electrocatalytic reduction reactions. Several representative examples are purposely selected for highlighting the huge potential of the seed‐mediated synthesis approach in chemical synthesis. Specifically, we personally perceive the seed‐mediated synthesis approach as a promising tool in the future for precise control over the size, shape, composition, structure, and exposed crystal facet of IMNCs.
