AbstractPerovskite light‐emitting diodes (PeLEDs) emerge as a promising kind of optoelectronic devices for the next‐generation full‐color display and white‐lighting technology. However, the performance of blue PeLEDs is far from satisfactory and some significant properties still remain unknown. Herein, for the first time, the active‐matrix display potential of blue PeLEDs has been unveiled by virtue of highly efficient, bright, and color‐stable blue PeLEDs. Through a synergistic strategy of ligand‐, anti‐solvent‐, device‐, and additive engineering, the photoluminescence quantum yield of blue perovskite films is as high as 76%. Blue PeLEDs exhibit a maximum external quantum efficiency of 9.81% at 251 cd m−2, a maximum power efficiency of 9.78 lm W−1, a peak luminance of 2298 cd m−2, and stable emissions, rendering that the performance is among the best blue PeLEDs. Furthermore, the integration applications of blue PeLEDs have been studied and the first prototype active‐matrix blue PeLED pixel circuit is demonstrated. Moreover, an unprecedented endeavor for active‐matrix flexible blue PeLEDs has been taken. The findings not only provide an alternative approach to achieve high‐performance blue PeLEDs, but also unlock the significant active‐matrix property of blue PeLEDs, which may pave the pathway for PeLED‐based display technology and related integrated optoelectronics.

Published: February 2023

AbstractAll life forms require pH homeostasis. The disorder of pH homeostasis is associated with many severe diseases, suggesting the significance of pH‐detection for theranostic diseases. Photoacoustic imaging (PAI) technology has piqued great research interests in spatiotemporal detection of pH in vivo due to its non‐invasiveness and non‐ionization, as well as the high resolution and deep tissue penetration. This mini‐review outlines the most recent advances in activatable organic PA probes for pH‐detection with respect to molecular design, response mechanisms, and their in vivo applications. The basic understanding of PA probes is clarified. The pH‐response mechanisms of the PA probes at the molecular level are particularly emphasized to elucidate the structural design strategies. Finally, the challenges and perspectives, mainly focusing on quantitative detection, are discussed. This review aims to pave the way for further exploration of responsive organic PA probes for in vivo pH‐detection.
Sensitive Stretchable and Pressable Mechanochromic Photonic Crystals for Dynamic Displays and Visual Sensing
Authors: Wei Boru , Hu Yang , Yang Dongpeng , Huang Shaoming 
Published: February 2023

AbstractMechanochromic photonic crystals (MPCs) have shown wide applications in visual sensing, displays, anti‐counterfeiting, etc. However, most reported MPCs can only sense stretching or pressure and exhibit poor sensitivity, which greatly limits their applications. Here, sensitive MPCs with brilliant structural colors capable of sensing both stretching and pressures are fabricated by combining self‐assembly and photo‐polymerization processes. The non‐closely packed structures and high reflectance enable MPCs with outstanding mechanochormic performances. The photo‐initiator concentration and thickness have a dramatic influence on the reflectance, wavelength, and even color uniformity. Interestingly, the same MPC shows diverse sensitivity values under stretching or pressing, and the sensitivity of the MPC by pressing is much higher than that by stretching due to their different deformations along three‐dimensional directions. These results are helpful for gaining a deeper understanding of the mechanochromic mechanism and sensitivity. In addition, dynamic patterns with tailorable color contrasts based on pressure and visual sensing based on stretching in practical applications are realized by taking the above advantages of MPCs. This study offers new insight into understanding mechanochromic behavior and will advance their applications in sensing, printing, and information encryption.
Evaluation of a high‐speed planter in soybean production

Published: February 2023

AbstractTimely and quality planting of soybean is important to achieve maximum yield potential. Wet spring soil conditions and rain frequently shorten the time for farmers to plant crops within optimal soil conditions. New planter technology has been introduced that enables farmers to plant their fields faster and more precisely than with traditional planters. Large plot field studies were conducted in Indiana from 2015 to 2017 to evaluate a high‐speed planter at various planting speeds with multiple seeding rates on soybean. Seedling emergence, plant distribution, and final yield were evaluated. Three planting speeds [8, 12, and 16 kilometers per hour (kph)] and two seeding rates (222,000 and 321,000 seeds ha−1) were included in all years, and an additional planting speed and seeding rate were included in 2016 (20 kph and 420,000 seeds ha−1, respectively). Overall, planting speed did not impact soybean seedling emergence. Uniformity of plant spacing decreased slightly as the planting speed increased from 8 to 20 kph in 2016. Cool and wet conditions immediately after planting likely led to inconsistent emergence. Final grain yield was not affected by planting speeds or seeding rate except in 2017 when 12 kph planting speed yielded 0.25 Mg ha−1 higher than the other planting speeds. Increasing planting speed can be achieved without detrimentally affecting plant population, plant spacing, and yield in soybean.

ObjectiveSpinal cord injury (SCI) damages synaptic connections between corticospinal axons and motoneurons of many muscles, resulting in devastating paralysis. We hypothesized that strengthening corticospinal‐motoneuronal synapses at multiple spinal cord levels through Hebbian plasticity (i.e., “neurons that fire together, wire together”) promotes recovery of leg and arm function.MethodsTwenty participants with chronic SCI were randomly assigned to receive 20 sessions of Hebbian or sham stimulation targeting corticospinal‐motoneuronal synapses of multiple leg muscles followed by exercise. Based on the results from this study, in a follow‐up prospective study, 11 more participants received 40 sessions of Hebbian stimulation targeting corticospinal‐motoneuronal synapses of multiple arm and leg muscles followed by exercise. During Hebbian stimulation sessions, 180 paired pulses elicited corticospinal action potentials by magnetic (motor cortex) and/or electrical (thoracic spine) stimulation allowing volleys to arrive at the spinal cord 1–2 milliseconds before motoneurons were activated retrogradely via bilateral electrical stimulation (brachial plexus, ulnar, femoral, and common peroneal nerves) for biceps brachii, first dorsal interosseous, quadriceps femoris, and tibialis anterior muscles as needed.ResultsWe found in our randomized study that participants receiving Hebbian stimulation improved their walking speed and corticospinal function to a greater extent than individuals receiving sham stimulation. In agreement, prospective study participants improved their grasping and walking, corticospinal function, and quality of life metrics, exhibiting greater improvements with more sessions that persisted 9‐month post‐therapy.InterpretationOur findings suggest that multisite Hebbian stimulation, informed by the physiology of the corticospinal system, represents an effective strategy to promote functional recovery following SCI.

Decoupled Artificial Photosynthesis
Authors: Zhang Linlin , Wang Yaobing 
Published: February 2023

AbstractNatural photosynthesis (NP) generates oxygen and carbohydrates from water and CO2utilizing solar energy to nourish lives and balance CO2levels. Following nature, artificial photosynthesis (AP), typically, overall water or CO2splitting, produces fuels and chemicals from renewable energy. However, hydrogen evolution or CO2reduction is inherently coupled with kinetically sluggish water oxidation, lowering efficiencies and raising safety concerns. Decoupled systems have thus emerged. In this review, we elaborate how decoupled artificial photosynthesis (DAP) evolves from NP and AP and unveil their distinct photoelectrochemical mechanisms in energy capture, transduction and conversion. Advances of AP and DAP are summarized in terms of photochemical (PC), photoelectrochemical (PEC), and photovoltaic‐electrochemical (PV‐EC) catalysis based on material and device design. The energy transduction process of DAP is emphasized. Challenges and perspectives on future researches are also presented.

AbstractDie enantioselektive Hydrierung von cyclischen Enamiden wurde mit einem Cobalt‐Bisphosphin‐Katalysator erreicht. Die Reduktion verschiedenster dreifach substituierter carbocyclischen Enamide zu den entsprechenden gesättigten Amiden erfolgte mit hoher Aktivität und ausgezeichneter Enantioselektivität (bis zu 99 %) unter Verwendung des Systems CoCl2/(S,S)‐Ph‐BPE. Die Methode lässt sich auf die Synthese chiraler Amine durch eine basische Hydrolyse der Hydrierungsprodukte ausweiten. Erste mechanistische Untersuchungen deuten auf die Anwesenheit einer high‐spin Cobalt(II)‐Spezie im katalytischen Cyclus hin. Wir postulieren die Hydrierung der Kohlenstoff‐Kohlenstoff‐Doppelbindung über einen Sigma‐Bindungs‐Metathese‐Weg.

AbstractTwo new ciprofloxacin (CF) monomers, (ACF) and (MCF) were designed and synthesized. Both ACF and MCF were polymerized using a redox‐initiated polymerization process, yielding the polymers PACF and PMCF, respectively. Three co‐polymers were prepared by polymerizing ACF with acrylamide (AcA), acrylonitrile (AcN), or N‐(thiazol‐2‐yl) acrylamide (NTA) monomers in a 1:3 molar ratio. Elemental analysis, X‐ray, IR, 1H and 13C NMR, and mass spectrometry were used to characterize the obtained monomers, polymers, and co‐polymers. The biological activities of the prepared monomers, polymers, and co‐polymers against Gram‐positive and Gram‐negative bacteria were investigated. Newly prepared compounds had a severe‐to‐mild impact on the microorganisms that were tested. Additionally, CF‐resistant bacteria were tested against newly prepared monomers and polyciprofloxacin. These data demonstrated that novel CF derivatives can overcome bacterial mutations that result in resistance to quinolone derivatives. Under acidic and basic conditions at 40°C, the sustained drug release of CF from polymeric chains and co‐polymers was studied. Drug release in the absence and presence of a catalytic quantity of potassium chloride at different concentrations, was studied and showed an increase in extended release. Drug release from the polymer and co‐polymer chains was measured by UV–visible spectroscopy. Morphologies and thermal stability of the prepared polymers and co‐polymers have also been reported.

Published: February 2023

AbstractThis study investigates the mediating role of internationalization readiness in the adoption of social sustainability practices (SSP) by companies in the Vietnamese handicraft industry. Data were collected from 325 Vietnamese handicraft companies through a questionnaire survey to empirically validate a conceptual model. The findings reveal that government, laborer, and market pressures on SSP adoption are fully mediated by internationalization readiness. The results also show that supplier pressures influence SSP adoption both directly and through internationalization readiness as a mediator. Furthermore, both internationalization readiness and SSP adoption can positively influence overall organizational performance. This study is the first of its kind to corroborate the application of the stakeholder theory and the resource‐based view theory to explore the impactful role of internationalization readiness in SSP adoption. It provides significant insights for managers, public policymakers, and sustainability practitioners to promote greater adoption of SSP across the entire supply chain through fostering internationalization readiness of companies.

AbstractBackgroundForkhead box L2 (FOXL2) has been recognized as a transcription factor in the progression of many malignancies, but its role in non‐small cell lung cancer (NSCLC) remains unclear. This research clarified on the role of FOXL2 and the specific molecular mechanism in NSCLC.MethodsRNA and protein levels were detected by quantitative real‐time polymerase chain reaction (qRT–PCR) and western blotting assays. Cell proliferation was examined by cell counting kit‐8 (CCK‐8) and clonogenic assays. Transwell and wound healing assays were used to detect cell invasion and migration. Cell cycle alterations were assessed by flow cytometry. The relationship between FOXL2 and miR‐133b was verified by dual‐luciferase reporter assays. In vivo metastasis was monitored in the tail vein‐injected mice.ResultsFOXL2 was upregulated in NSCLC cells and tissues. Downregulation of FOXL2 restrained cell proliferation, migration, and invasion and arrested the cell cycle of NSCLC cells. Moreover, FOXL2 promoted the epithelial–mesenchymal transition (EMT) process of NSCLC cells by inducing the transforming growth factor‐β (TGF‐β)/Smad signaling pathway. miR‐133b directly targeted the 3′‐UTR of FOXL2 and negatively regulated FOXL2 expression. Knockdown of FOXL2 blocked metastasis in vivo.ConclusionsmiR‐133b downregulates FOXL2 by targeting the 3′‐UTR of FOXL2, thereby inhibiting cell proliferation, EMT and metastasis induced by the TGF‐β/Smad signaling pathway in NSCLC. FOXL2 may be a potential molecular target for treating NSCLC.

AbstractThe inherent shortcomings of a zinc anode in aqueous zinc‐ion batteries (ZIBs) such as zinc dendrites and side reactions severely limit their practical application. Herein, to address these issues, an ion‐oriented transport channel constructed by graphdiyne (GDY) nanowalls is designed and grown in situ on the surface of a zinc electrode. The vertically stacked GDY nanowalls with a unique hierarchical porous structure and mechanical properties form a nanomesh‐like interface on the zinc electrode, acting as an ion‐oriented channel, which can efficiently confine the segmented growth of zinc metal in microscopic regions of hundreds of nanometers. In those microscopic regions, the uniform domain current density is effortlessly maintained compared with a large surface area, thereby inhibiting zinc dendrites effectively. Besides, due to the presence of the ion‐oriented channel, the modified zinc anode demonstrates long‐term stable zinc plating/stripping performance for more than 600 h at 1 mAh cm−2 in an aqueous electrolyte. In addition, full‐cells coupled with MnO2 show high specific capacity and power density, as well as excellent cycling stability with a capacity retention of 82% after 5000 cycles at 1 A g−1. This work provides a feasible and accessible surface engineering approach to modify the electrode interface for confined and dendrite‐free zinc deposition in aqueous ZIBs.

Published: February 2023

AbstractDuring the last three decades, silicon‐bridged [1]ferrocenophanes have been developed into an important class of monomers with the resulting polymers being the subject of hundreds of publications. For unknown reasons, not a single example of a silicon‐bridged [1]ruthenocenophane is described in the literature. We set out to address this mystery and could synthesize the first sila[1]ruthenocenophanes. Their molecular structures as well as their heat release in the melt, render them as highly strained sandwich compounds that are polymerizable. Why did it take so long to prepare the first sila[1]ruthenocenophanes? This question is addressed by a detailed analysis of the kinetics of the salt‐metathesis approach, which reveals a striking difference between ferrocene and ruthenocene.

Published: February 2023

AbstractDomestic pigs have a prominent cortical gyrus (the rostrum gyrus) isomorphic to the contralateral hemirostrum. It is unclear, however, if the size and shape of the rostrum gyrus are of evolutionary/functional relevance. Here, we address this question by assessing the relationship of rostrum and rostrum gyrus across eight pig species. To this end, we quantified rostrum morphology in fresh and alcohol‐preserved pig specimens by surface scans, microfocus computed tomography scans, and photography. We establish that the size and shape of the rostrum gyrus can be precisely inferred from endocasts. We then took advantage of the accessibility of pig skulls and endocasts to assess features of the rostrum gyrus across species. Our investigation led to the following results: (i) The rostra of pig species show basic similarities. (ii) A cortical rostrum gyrus is apparent in all pigs. (iii) The size of the rostrum gyrus differs across species and outgroups of the evolutionary dominant suinae (i.e., peccaries and the babirusa) have a noticeably smaller rostrum gyrus. (iv) Warthogs have a derived rostrum morphology with an extra fold and a very wide rostrum; the warthog rostrum gyrus recapitulates these rostrum features. (v) Domestic pigs have relatively smaller rostrum gyrus than wild boars. We also provide indications for a conserved cytoarchitectonic patterning of the rostrum gyrus. We conclude that the rostrum gyrus is a neural module that was putatively present in the common ancestor of pigs and that this neural module is conserved across pig species. Natural selection maintains the rostrum gyrus’ size and its exact isomorphism to the rostrum.

AbstractMulti‐mode vibronic coupling in the,,andelectronic states of Cyanogen radical cation (CN) is investigated with the aid ofab initioquantum chemistry and first principles quantum dynamics methods. The electronic degenerate states of Π symmetry of CNundergo Renner‐Teller (RT) splitting along degenerate vibrational modes ofπsymmetry. The RT split components form symmetry allowed conical intersections with those from nearby RT split states or with non‐degenerate electronic states of Σ symmetry. A parameterized vibronic Hamiltonian is constructed using standard vibronic coupling theory in a diabatic electronic basis and symmetry rules. The parameters of the Hamiltonian are derived fromab initiocalculated adiabatic electronic energies. The vibronic spectrum is calculated, assigned and compared with the available experimental data. The impact of various electronic coupling on the vibronic structure of the spectrum is discussed.

AbstractClenbuterol (Clb) (4‐amino‐α‐[(tert‐butylamine) methyl]‐3,5‐dichlorobenzyl alcohol) is a sympathomimetic agent that exhibits β2‐agonist activity. It is applied as a bronchodilatory, tocolytic, and mucolytic agent and is authorized for clinical management in both human and veterinary therapeutics as a racemic mixture. However, its use is strictly prohibited in animals destined for food production in countries in the European Union and in the United States and Mexico, among many others. The R‐(−) enantiomer in clenbuterol stimulates β2‐receptors, whereas the S‐(+) enantiomer blocks the effect of β1‐receptors. The aims of this study were to develop a method for detecting and quantifying Clb and its enantiomeric distribution in several bovine tissues. The UHPLC‐MS/MS method developed to quantify the target compound at trace levels in these tissues combines high sensitivity with good selectivity and short chromatographic run time. The tissue samples tested were found to contain racemic Clb in concentrations of 5–447 pg g−1. The enantiomeric analysis of Clb showed that R‐(−)‐Clb is present at higher concentrations in some tissues, whereas S‐(+)‐Clb was detected in a ratio of 55/45 in the liver and heart tissues.
