Published: May 2024

AbstractMolecular scaffolds are ideal for investigating upconversion (UC) at the highest spatial resolution and to create precisely controllable luminescent materials. Such control may be the key to overcoming the limitations of brightness and reproducibility found in UC micro‐ and nanoparticles. Cooperative UC can significantly increase luminescence brightness and bulk studies showed that highest efficiencies can be obtained by sensitizer‐to‐activator ion ratios ≥ 2, that is, via high probabilities of sensitizing the emitting lanthanide ion. Using nonanuclear molecular complexes, the authors demonstrate both experimentally and theoretically that interion distances are more relevant and that the highest UC efficiencies are actually attained for sensitizer‐to‐activator ion ratios around 1. By modeling accretive and cooperative sensitization UC, energy migration, and fitting experimental data, it is revealed that cooperative sensitization is predominant for the determination of UC luminescence intensities, whereas energy migration defines UC luminescence kinetics. The implementation of interion distances and different energy transfer mechanisms into advanced modeling of experimental UC data will be paramount for designing brighter and better UC materials.

AbstractTherapeutic mRNA vaccines have become powerful therapeutic tools for severe diseases, including infectious diseases and malignant neoplasms. mRNA vaccines encoding tumor‐associated antigens provide unprecedented hope for many immunotherapies that have hit the bottleneck. However, the application of mRNA vaccines is limited because of biological instability, innate immunogenicity, and ineffective delivery in vivo. This study aims to construct a novel mRNA vaccine delivery nanosystem to successfully co‐deliver a tumor‐associated antigen (TAA) encoded by the Wilms' tumor 1 (WT1) mRNA. In this system, named PSB@Nb1.33C/mRNA, photosynthetic bacteria (PSB) efficiently delivers the iMXene‐WT1 mRNA to the core tumor region using photo‐driven and hypoxia‐driven properties. The excellent photothermal therapeutic (PTT) properties of PSB and 2D iMxene (Nb1.33C) trigger tumor immunogenic cell death, which boosts the release of the WT1 mRNA. The released WT1 mRNA is translated, presenting the TAA and amplifying immune effect in vivo. The designed therapeutic strategy demonstrates an excellent ability to inhibit distant tumors and counteract postsurgical lung metastasis. Thus, this study provides an innovative and effective paradigm for tumor immunotherapy, i.e., photo‐immunogene cancer therapy, and establishes an efficient delivery platform for mRNA vaccines, thereby opening a new path for the wide application of mRNA vaccines.

AbstractFerroelectric field‐effect transistors (FeFETs) are increasingly important for in‐memory computing and monolithic 3D (M3D) integration in system‐on‐chip (SoC) applications. However, the high‐temperature processing required by most ferroelectric memories can lead to thermal damage to the underlying device layers, which poses significant physical limitations for 3D integration processes. To solve this problem, the study proposes using a nanosecond pulsed laser for selective annealing of hafnia‐based FeFETs, enabling precise control of heat penetration depth within thin films. Sufficient thermal energy is delivered to the IGZO oxide channel and HZO ferroelectric gate oxide without causing thermal damage to the bottom layer, which has a low transition temperature (<250 °C). Using optimized laser conditions, a fast response time (<1 µs) and excellent stability (cycle > 106, retention > 106 s) are achieved in the ferroelectric HZO film. The resulting FeFET exhibited a wide memory window (>1.7 V) with a high on/off ratio (>105). In addition, moderate ferroelectric properties (2·Pr of 14.7 µC cm−2) and pattern recognition rate‐based linearity (potentiation: 1.13, depression: 1.6) are obtained. These results demonstrate compatibility in HZO FeFETs by specific laser annealing control and thin‐film layer design for various structures (3D integrated, flexible) with neuromorphic applications.

AbstractLithium (Li)‐rich transition metal oxide cathodes with a cation disordered rock salt structure (DRX) are increasingly gaining popularity for advanced Li batteries as they offer high capacity and cost benefits over the commonly used layered Li transition metal oxide cathodes. However, the performance of DRX cathodes and their applications are limited by severe side reactions between the cathode and the state‐of‐the‐art carbonate‐based electrolytes at high voltage of 4.8 V, transition metal dissolution, and structural instability of the cathode particles. In this work, an advanced localized high‐concentration electrolyte (LHCE) is developed to form a stable cathode‐electrolyte interphase and mitigate structural instability of the Li1.13Mn0.66Ti0.21O2 (LMTO) DRX during electrochemical cycling. Li||LMTO half cells with the LHCE demonstrate increased capacity, cycling stability, and superior rate capability compared with cells containing a conventional carbonate electrolyte. For instance, the Li||LMTO cells cycled in LHCE show a higher initial capacity of 205.2 mAh g−1 and a better capacity retention of 72.5% after 200 cycles at a current density of 20 mA g−1 than those with the conventional electrolyte (initial capacity of 187.7 mAh g−1 and capacity retention of 19.9%). This work paves the way to the development of practical DRX cathode‐based high‐energy Li batteries.

Published: May 2024

AbstractSingle‐atom catalysts (SACs) exhibit excellent electrocatalytic performance in various catalytic reactions. However, the low metal loading (<1.0 wt.%) and the difficulty in precisely modulating their coordination configurations hinder the practical yield of target products and the understanding of actual reaction mechanisms. To overcome these obstacles, a series of strategies are proposed to design SACs with a precise coordination configuration and/or a high density of active sites. For an insightful and comprehensive understanding of these strategies, it is worth analyzing and categorizing them according to their intrinsic mechanisms and applicational perspectives. In this review, the synthesis strategies of precise and/or high‐density SACs are first summarized. Moreover, taking typical electrochemical processes, including oxygen reduction reaction, nitrogen reduction reaction, and carbon dioxide reduction reaction, metal–sulfur batteries, etc., as examples, the applications of these SACs are discussed, focusing on their advantages in enhancing the yield of target products, improving the efficiency of energy storage, and revealing the unique effects. Finally, the challenges and perspective of precise modulation and densification of metal sites for SACs are proposed. It is expected that this review can provide a useful reference for the design and preparation of high‐density and/or controllably coordinated SACs.
Correcting the record: Phonetic potential of primate vocal tracts and the legacy of Philip Lieberman (1934−2022)
Authors: Ekström Axel G. 
Published: May 2024

AbstractThe phonetic potential of nonhuman primate vocal tracts has been the subject of considerable contention in recent literature. Here, the work of Philip Lieberman (1934−2022) is considered at length, and two research papers—both purported challenges to Lieberman's theoretical work—and a review of Lieberman's scientific legacy are critically examined. I argue that various aspects of Lieberman's research have been consistently misinterpreted in the literature. A paper by Fitch et al. overestimates the would‐be “speech‐ready” capacities of a rhesus macaque, and the data presented nonetheless supports Lieberman's principal position—that nonhuman primates cannot articulate the full extent of human speech sounds. The suggestion that no vocal anatomical evolution was necessary for the evolution of human speech (as spoken by all normally developing humans) is not supported by phonetic or anatomical data. The second challenge, by Boë et al., attributes vowel‐like qualities of baboon calls to articulatory capacities based on audio data; I argue that such “protovocalic” properties likely result from disparate articulatory maneuvers compared to human speakers. A review of Lieberman's scientific legacy by Boë et al. ascribes a view of speech evolution (which the authors term “laryngeal descent theory”) to Lieberman, which contradicts his writings. The present article documents a pattern of incorrect interpretations of Lieberman's theoretical work in recent literature. Finally, the apparent trend of vowel‐like formant dispersions in great ape vocalization literature is discussed with regard to Lieberman's theoretical work. The review concludes that the “Lieberman account” of primate vocal tract phonetic capacities remains supported by research: the ready articulation of fully human speech reflects species‐unique anatomy.

AbstractCoinage metals Cu, Ag, and Au are essential for modern electronics and their recycling from waste materials is becoming increasingly important to guarantee the security of their supply. Designing new sustainable and selective procedures that would substitute currently used processes is crucial. Here, we describe an unprecedented approach for the sequential dissolution of single metals from Cu, Ag, and Au mixtures using biomass‐derived ionic solvents and green oxidants. First, Cu can be selectively dissolved in the presence of Ag and Au with a choline chloride/urea/H2O2 mixture, followed by the dissolution of Ag in lactic acid/H2O2. Finally, the metallic Au, which is not soluble in either solution above, is dissolved in choline chloride/urea/Oxone. Subsequently, the metals were simply and quantitatively recovered from dissolutions, and the solvents were recycled and reused. The applicability of the developed approach was demonstrated by recovering metals from electronic waste substrates such as printed circuit boards, gold fingers, and solar panels. The dissolution reactions and selectivity were explored with different analytical techniques and DFT calculations. We anticipate our approach will pave a new way for the contemporary and sustainable recycling of multi‐metal waste substrates.

Published: May 2024

AbstractRational design of advanced electrolytes to improve the high‐voltage capability has been attracting wide attention as one critical solution to enable next‐generation high‐energy‐density batteries. However, the limited understanding of electrolyte antioxidant chemistry as well as the lack of valid quantization approaches have resulted in knowledge gap, which hinders the formulation of new electrolytes. Herein, we construct a standard curve based on representative solvation structures to quantify the oxidation stability of ether‐based electrolytes, which reveals the linear correlation between the oxidation potential and the atomic charge of the least oxidation‐resistant solvent. Dictated by the regularity between solvation composition and oxidation potential, a (Trifluoromethyl)cyclohexane‐based localized high‐concentration electrolyte dominated by anion‐less solvation structures was designed to optimize the cycling performance of 4.5 V 30 μm‐Li||3.8 mAh cm−2‐LiCoO2 batteries, which maintained 80 % capacity retention even after 440 cycles. The consistency of experimental and computational results validates the proposed principles, offering a fundamental guideline to evaluate and design aggressive electrochemical systems.

AbstractManufacturing PHBV biocomposites with spent coffee ground (SCG) is an eco‐friendly approach of repurposing waste materials to improve sustainability. Although, as shown previously, pretreatments of SCG can improve its interaction with PHBV to obtain enhanced properties, the chemical or biological treatment could be time‐consuming, costly, and environmentally harmful. Therefore, this study developed a method of manufacturing PHBV/SCG biocomposites via a simple and industrially viable reactive extrusion method requiring no SCG pretreatment. The present work aims at investigating the impact of untreated SCG combined with different processing additives (peroxide, coagent, and chain extender) on the morphological, thermal, mechanical, and water absorption properties of PHBV‐based biocomposites. Overall, the introduction of the untreated SCG (10–30 wt.%, without processing additives) decreased the crystallinity (by 3.8%–6.8%), degradation temperature (Tpeak, by 6.2%–8.2%) and tensile strain (by 33%–43%) of PHBV. SCG addition had no significant effect on PHBV tensile strength or Young's modulus. However, the presence of processing additives decreased the melting temperature (by up to 4.5°C), crystallinity (by up to 8.4%) and Young's modulus (by up to 17%) and increased the degradation temperature (Tpeak, by up to 12.5°C) of the PHBV/SCG biocomposites (10% wt.% SCG). Lastly, SCG addition improved water absorption ability of PHBV by up to 250%, while the addition of peroxide further improved the water absorption ability by approximate 320%. The PHBV/SCG developed in this study have good renewability and biodegradability, improved water absorption property, reduced cost and acceptable mechanical properties. They are promising in applications where biodegradability is favorable and high mechanical performance is not required such as plant pots and containers.

Published: May 2024

AbstractRational construction of oxygen vacancies in electrode materials can effectively enhance the comprehensive sodium storage performance of the material. However, how to precisely control and regulate the oxygen vacancies concentration remains to be investigated, and the impact on electrochemical performance is still unclear. Herein, TiO2 nanoparticles with tunable oxygen vacancies concentrations are used as research models, which were fabricated through a simple and effective plasma method. The experimental results reveal that a moderate concentration of oxygen vacancies can significantly improve the electrochemical kinetics and charge conductivity of the TiO2 electrodes. In addition, oxygen vacancies promote the release of fluorine from the fluoroethylene carbonate (FEC) in the electrolyte, inducing a NaF‐rich solid electrolyte interphase, thus ensuring interfacial stability and inhibiting excessive electrolyte decomposition. Consequently, the well‐designed anode exhibits outstanding rate capability (147 mAh g−1 at 5 A g−1) and extremely stable cycling performance (nearly 100 %, 3000 cycles). This work provides a feasible method for realizing defect concentration modulation in energy storage materials and offers new insights into interfacial chemistry for improving battery performance.
The pursuit of the ideal self: An investigation of the relationship of authenticity and ideal self‐congruence
Authors: Zogaj Adnan , Mähner Philipp M. , Tscheulin Dieter K. 
Published: May 2024

AbstractResearch suggests that authentic branding strategies should focus on consumers' actual self rather than their ideal self; that is, brands that match consumers' ideal self are perceived as too psychologically distant from their present self and, thus, as inauthentic. This study challenges this prevailing notion by proposing the novel perspective that ideal self‐congruence is more influential than actual self‐congruence in driving authenticity. Contrary to the view that brands matching consumers' ideal self are deemed inauthentic due to psychological distance, our research, encompassing four empirical studies, demonstrates that ideal self‐congruence significantly enhances positive authentic pride while effectively reducing negative hubristic pride more than actual self‐congruence. Furthermore, this study not only reveals that ideal self‐congruence is more strongly associated with authentic pride than actual self‐congruence but also reshapes the theoretical understanding of the role of self‐congruence in the realm of authenticity. Our findings therefore contradict previously cited but hardly empirical arguments by demonstrating that ideally self‐congruent brands positively affect perceived brand authenticity more than actually self‐congruent brands. Thus, we recommend brands to focus authentic marketing strategies on consumers' ideal self to positively influence consumer behavior.

Copper‐Nickel Alloy Modified‐Silicon Photoanodes for Photoelectrochemical Water Oxidation and Urea Oxidation
Authors: Klahan Kanokwan , Loget Gabriel , Pattanasattayavong Pichaya 
Published: May 2024

AbstractThe development of silicon (Si) photoanodes for photoelectrochemical (PEC) oxidation is highly crucial for the progress of solar‐driven hydrogen production. Apart from the typical water oxidation reaction or oxygen evolution reaction (OER), the urea oxidation reaction (UOR) is gaining more attention due to favorable thermodynamics. In this work, we study Si photoanodes modified with electrodeposited copper‐nickel (CuNi) alloy for OER and UOR. The optimized photoanodes exhibit a low onset potential of 1.15 V vs reversible hydrogen electrode (RHE) and a current density of 6 mA cm−2 at 1.23 V vs RHE (the thermodynamic potential for water oxidation) for OER. Further, CuNi alloy‐modified photoanodes can drive the UOR at a lower onset potential (1.05 V vs RHE) and generate a higher current density of 31 mA cm−2 at 1.23 V vs RHE. Importantly, the CuNi alloy can extend the stability for UOR under PEC conditions when compared to a planar Ni film deposited by a vacuum‐based process. This work demonstrates that CuNi alloy can further improve the properties of inhomogeneous metal‐insulator‐semiconductor Si photoanodes which can be efficiently utilized for both OER and UOR.

Published: May 2024

AbstractThe separation of carbon dioxide (CO2) from nitrogen (N2) is at the core of any global warming remediation technology aimed at reducing the CO2 content in the atmosphere. Chemical membranes designed to differentially permeate both molecules have become quite appealing due to their simple use, although many membrane‐based separations stand out as a promising solution for CO2 separation. These are environmentally friendly, with high active surface areas, compact design, easy to maintain and cost‐effective, although the field is still growing due to the difficulties in the CO2/N2 separation. The present study poses grazynes, two‐dimensional C‐based materials with sp and sp2 C atoms, aligned along stripes, as suited membranes for the CO2/N2 separation. The combination of density functional theory (DFT) and molecular dynamics (MD) simulations allow tackling the energetics, kinetics, and dynamics of the membrane effectiveness of grazynes with engineered pores for such a separation in a holistic fashion. The explored grazynes are capable of physisorbing CO2 and N2, thus avoiding material poisoning by molecular decoration, while the diffusion of CO2 through the pores is found to be rapid, yet easier than that of N2, in the rate order of the s−1 in the 100–500 K temperature range. In particular, low‐temperature CO2 separation even for CO2 contents below 0.5 % are found for [1],[2]{2}‐grazyne when controlling the membrane exposure contact to the gas mixture, paving the way for exploring and using grazynes for air CO2 remediation.
