Published: January 2024

AbstractExtracting lithium selectively and efficiently from brine sources is crucial for addressing energy and environmental challenges. The electrochemical system employing LiMn2O4 (LMO) electrodes has been recognized as an effective method for lithium recovery. However, the lithium selectivity and stability of LMO need further enhancement for its practical applications. Herein, the Al‐doped LMO with reduced lattice constant is successfully fabricated through a facile one‐step solid‐state sintering method, leading to enhanced lithium selectivity. The reduced lattice constant in Al‐doped LMO is proved through spectroscopic analyses and theoretic calculations. Compared to the original LMO, the Al‐doped LMO (LiAl0.05Mn1.95O4, LMO‐Al0.05) exhibits highercapacitance, lower resistance, and improved stability. Moreover, the LMO‐Al0.05 with reduced lattice constant can offer higher Li+ diffusion coefficient and lower intercalation energy revealed by cyclic voltammetry and multiscale simulations. When employed in hybrid capacitive deionization (CDI), the LMO‐Al0.05 obtains a Li+ intercalation capacity of 21.7 mg g−1 and low energy consumption of 2.6 Wh mol−1 Li+. Importantly, the LMO‐Al0.05 achieves a high Li+ extraction percentage (≈86%) with Li+/Na+ and Li+/Mg2+ selectivity of 1653.8 and 434.9, respectively, in synthetic brine. The results demonstrate that the Al‐doped LMO with reduced lattice constant could be a sustainable solution for electrochemical lithium extraction.

AbstractLayered transition‐metal (TM) oxide cathodes have attracted growing attention in sodium‐ion batteries (SIBs). However, their practical implementation is plagued by Jahn–Teller distortion and irreversible cation migration, leading to severe voltage decay and structure instability. Herein, O3‐Na0.898K0.058Ni0.396Fe0.098Mn0.396Ti0.092O2 (KT‐NFM) is reported as an ultrastable cathode material via multisite substitution with rigid KO6 pillars and flexible TiO6 octahedra. The K pillars induce contracted TMO2 slabs and their strong Coulombic repulsion to inhibit Ni/Fe migration; and Ti incorporation reinforces the hybridization of Ni(3deg*)‐O(2p) to mitigate the undesired O3–O'3 phase transition. These enable the reversible redox of Ni2+↔Ni3.20+ and Fe3+↔Fe3.69+ for 138.6 mAh g−1 and ultrastable cycles with >90% capacity retention after 2000 cycles in a pouch cell of KT‐NFM||hard carbon. This will provide insights into the design of ultrastable layered cathode materials of sodium‐ion batteries and beyond.

Published: January 2024

AbstractAs a pioneering battery technology, even though sodium‐ion batteries (SIBs) are safe, non‐flammable, and capable of exhibiting better temperature endurance performance than lithium‐ion batteries (LIBs), because of lower energy density and larger ionic size, they are not amicable for large‐scale applications. Generally, the electrochemical storage performance of a secondary battery can be improved by monitoring the composition and morphology of electrode materials. Because more is the intricacy of a nanostructured composite electrode material, more electrochemical storage applications would be expected. Despite the conventional methods suitable for practical production, the synthesis of metal–organic frameworks (MOFs) would offer enormous opportunities for next‐generation battery applications by delicately systematizing the structure and composition at the molecular level to store sodium ions with larger sizes compared with lithium ions. Here, the review comprehensively discusses the progress of nanostructured MOFs and their derivatives applied as negative and positive electrode materials for effective sodium storage in SIBs. The commercialization goal has prompted the development of MOFs and their derivatives as electrode materials, before which the synthesis and mechanism for MOF‐based SIB electrodes with improved sodium storage performance are systematically discussed. Finally, the existing challenges, possible perspectives, and future opportunities will be anticipated.
Giant Change in Electrical Resistivity Induced by Moderate Pressure in Pt(bqd)2 – First Candidate Material for an Organic Piezoelectronic Transistor (OPET)
Authors: Afanasjevs Sergejs , Benjamin Helen , Kamenev Konstantin , Robertson Neil 
Published: January 2024

AbstractThe piezoelectronic transistor (PET) has been proposed to overcome the voltage and clock speed limitations of conventional field‐effect transistors (FET). In a PET, voltage is transduced to stress, which leads to an insulator‐metal transition in a piezo‐resistive (PR) element. Although the simulated switching speeds are promising, the viable candidates proposed so far for the PR layer are rare earth compounds that require several GPa of pressure (P) to metalize, necessitating breakthroughs in transduction mechanism scaling and processing. Here, a PR candidate that metalizes in the 0–300 MPa range – the transition metal complex platinum benzoquinonedioximato (Pt(bqd)2) is demonstrated. Such electrical sensitivity to the application of P arises when the material is grown as a thin film with the preferred needle orientation perpendicular to the substrate. As evidence, a combination of hydrostatic and uniaxial pressure studies is provided. The former studies are produced on the compressed powder pellet in a specially developed piston‐cylinder cell (P‐C cell) under variable temperatures (T) and P. The latter is via thin film deposition and uniaxial resistivity (ρ) measurements and these revealed the high potential of this material for the PET concept.

Published: January 2024

AbstractWe evaluate the overall sensitivity gains provided by a series of eighteen nitroxide biradicals for dynamic nuclear polarization (DNP) solid‐state NMR at 9.4 T and 100 K, including eight new biradicals. We find that in the best performing group the factors contributing to the overall sensitivity gains, namely the DNP enhancement, the build‐up time, and the contribution factor, often compete with each other leading to very similar overall sensitivity across a range of biradicals. NaphPol and HydroPol are found to provide the best overall sensitivity factors, in organic and aqueous solvents respectively. One of the new biradicals, AMUPolCbm, provides high sensitivity for all three solvent formulations measured here, and can be considered to be a “universal” polarizing agent.

Abstract

The western Mediterranean Sea has traditionally served as a primary foraging ground for juvenile loggerhead turtles from three distinct regional management units: the North‐western Atlantic, the Mediterranean and Cape Verde. Nesting activities were sporadic.
Recently, nesting activity on the beaches of eastern Spain has increased, due to warmer sand and water temperatures during the summer months.
The study has integrated stable isotope analysis of carbon (C), nitrogen (N) and sulphur (S) with satellite telemetry to identify the foraging grounds of these new colonizers nesting on Spanish beaches.
Results indicate that the majority of these adult females forage oceanically in the Algerian Basin, with a few exhibiting distinct stable isotope signals, tentatively associated with foraging in shallow coastal areas in the central Mediterranean Sea.
The dominance of oceanic foragers in this new population is noteworthy, given the Algerian Basin's oligotrophic nature. This contrasts with the prevalence of neritic foraging in adult females nesting in the central and eastern Mediterranean Sea.
The use of the Algerian Basin as a foraging ground for adult loggerhead turtles exposes them to bycatch from drifting longlines. The authorities should refrain from increasing bluefin quotas imposed on longliners in the Algerian Basin unless the fishery avoids using squid as bait and agrees to deploy hooks deeper than 25 m to reduce loggerhead turtle bycatch.
Phenomenon‐based classification: An Annual Review of Information Science and Technology (ARIST) paper
Authors: Gnoli Claudio , Smiraglia Richard P. , Szostak Rick 
Published: January 2024

AbstractWhile bibliographic classifications are traditionally based on disciplines, the logical alternative is phenomenon‐based classification. Although not prevalent, this approach has been explored in the 20th century by J.D. Brown, the Classification Research Group, and others. Its principles have been stated in the León Manifesto (2007) and are currently represented by such general schemes as the Basic Concepts Classification and the Integrative Levels Classification. A phenomenon‐based classification lists classes of phenomena, including things and processes irrespective of the discipline studying them (which can optionally be specified as an additional facet). Facets can work in a phenomenon‐based system much as in a disciplinary one. This kind of system will promote the identification of potential relationships between research in different disciplines, and will especially benefit interdisciplinary work. The paper reviews the theory, history, structure, advantages, applications, and evaluation of phenomenon‐based classification systems.
An anti‐windup and backlash compensation‐based finite‐time control method for performance enhancement of a class of nonlinear systems
Authors: Liu Guangyu , Ma Wenyu , Zhang Yanxin 
Published: January 2024

AbstractReal‐world nonlinear control systems (e.g., robots) are influenced dynamically by backlash and saturation. However, it is lacking of a control design tool with a sound theory to deal with these phenomena and achieve optimal finite‐time stability simultaneously. To this end, we propose a novel anti‐windup and backlash compensation‐based finite‐time control (AWBC‐FTC) method for an unsolved control task of a general class of unstable nonlinear systems under input saturation and backlash nonlinearity. It includes a compound control structure with two layers where the upper switches two control modes and the lower regulates the system in either the backlash mode or the contact mode. New stability theory together with parameter optimization algorithms are also proposed to support new design approaches of two sub‐controllers where the adversary effects of input saturation and backlash are eliminated and the optimal finite state stability under a guaranteed domain of attraction is achieved. Experimental results on a benchmark robot system verify the advantages of the proposed design tools over the other in terms of a bunch of transient and stability measures. Therefore, the work enriches both theory and design of nonlinear systems for a challenging control objective.

AbstractMicroalgae are a rich source of bioactive compounds such as pigments, carbohydrates, lipids, proteins, and other substances of interest. Thus, given the possible variety of products that can be obtained from them, it is important to determine their biochemical composition, taking into consideration the species and cultivation conditions, so that they can be used as feedstock in biorefineries, with the aim of using all the biomass in the biorefining processes and increasing its economic viability. This work aimed to characterize the biochemical composition of the microalgae Dunalliela salina in a multi‐product biorefinery context, focusing on the production of high value‐added compounds such as pigments and biofuels. The biomass concentration obtained was 1.15 g·L−1 and the volumetric productivity was 164.28 mg·L−1·day−1, providing fractions of 23.86 ± 0.24% of lipids, 10.80 ± 0.86% of carbohydrates, and 5.71 ± 0.50% of proteins. The microalgal biomass contained pigment concentrations of 0.896 and 0.5380 mg·g−1of chlorophylls a and b, and 0.2043 mg·g−1 of total carotenoids. Thus, the data suggest that D. salina has biotechnological potential for application in integrated multi‐product biorefineries, focused on obtaining energy and high added value products simultaneously.
Deciphering the role of Zn2+‐binding histidines from TIA‐1 on the assembly and dynamics of stress granules
Authors: Corrales‐Guerrero Laura , Díaz‐Moreno Irene 
Published: January 2024

AbstractT‐cell intracellular antigen‐1 (TIA‐1) is a key RNA‐binding protein that participates in translation regulation and RNA splicing. TIA‐1 undergoes liquid–liquid phase separation as a fundamental mechanism that enables the condensation of RNA and proteins into membraneless organelles called stress granules (SGs). However, this dynamic behavior can lead to aberrant fibril formation, implicated in neurodegenerative disorders, and must be tightly regulated. In this study, we investigated the role in the cell of histidine residues His94 and His96, responsible for Zn2+ binding. Using fluorescence microscopy, we found that the specific binding site formed by these residues is critical for SG assembly. Furthermore, it also plays a role maintaining the dynamic behavior of SG‐assembled TIA‐1. Collectively, our findings confirm the physiological relevance of TIA‐1 His94 and His96 in the Zn2+‐mediated regulatory mechanism for protection against fibril formation in SGs.
Writing a literature review as a class project in an upper‐level undergraduate biochemistry course

Published: January 2024

AbstractA literature review is an important part of conducting academic research. Knowing how to conduct a literature search and write a high‐quality literature review is a valuable skill. Herein, the authors describe the method of introducing a literature review writing exercise in an upper‐level biochemistry course. Since 2020, authors have collaborated with numerous undergraduates writing literature reviews on topics in biochemistry that resulted in peer‐reviewed publications. Authors believe that this unique idea of providing a course‐based undergraduate research experience (CURE) to many undergraduates, especially those who otherwise do not receive collaborative research experience through traditional research paths, must be shared with other instructors.
Using blockchain or not? A focal firm's blockchain strategy in the context of carbon emission reduction technology innovation
Authors: Zhu Jianhua , Feng Taiwen , Lu Ying , Jiang Wenbo 
Published: January 2024

AbstractRecently, blockchain has been increasingly applied to low‐carbon supply chains, enabling consumers to track production process of low‐carbon products, thereby improving brand awareness and expanding the market. However, do the operation and construction costs of blockchain come at the expense of squeezing resources originally allocated for research and development (R&D) of carbon emission reduction (CER) or reducing firms profits? Given the varying capacities of different types of firms to bear the costs of blockchain in the process of R&D of CER, this paper considers two categories of firms, superior brand firms and inferior brand firms, and studies the impact of blockchain usage on CER and profits. Research shows that the usage of blockchain is not necessarily beneficial to CER and profits enhancement. Consumers' trust and low‐carbon preference, brand awareness, blockchain operation and construction costs, and R&D difficulty of CER are key factors. Superior brand firms can improve CER level and profits through blockchain when R&D difficulty is low and consumers' trust is high or when R&D difficulty is high but consumers' low‐carbon preferences and brand awareness are high. Inferior brand firms can improve CER level and profits through blockchain when R&D difficulty is low and consumers' trust is high or when R&D difficulty is high but brand awareness is low. This study provides strategic insights for brand firms considering the usage of blockchain in their CER initiatives, highlighting the importance of aligning blockchain integration with firm‐specific characteristics and market conditions to achieve both environmental and profit objectives.

Recently, X‐ray techniques emerged as revolutionary tools to reveal an in‐depth understanding of the battery during operations. This review provides an overview of the use of in situ/operando X‐ray techniques to understand the different functionalities of electrode materials inside the battery. It will focus on the phase transformation, structural evolution and dynamic properties of the battery electrodes, and discuss the relationship between battery failure and electro‐chemo‐mechanical failure in the electrode. Finally, the limitations of these methods are also discussed with the prospects for effective use of these techniques in the development of advanced battery technologies.

Published: January 2024

AbstractDespite their great promise as high‐energy‐density alternatives to Li‐ion batteries, the extensive use of lithium‐oxygen (Li‐O2) batteries is constrained by the slow kinetics of both the oxygen evolution reaction and oxygen reduction reaction. To increase the overall performance of Li‐O2 batteries, it is essential to increase the efficiency of oxygen electrode reactions by constructing effective electrocatalysts. As a high‐efficiency catalyst for Li‐O2 batteries, high entropy perovskite oxide (La0.8Sr0.2)(Mn0.2Fe0.2Cr0.2Co0.2Ni0.2)O3 (referred to as LS(MFCCN)O3) is designed and investigated in this article. The introduction of dissimilar metals in LS(MFCCN)O3 has the potential to cause lattice deformation, thereby enhancing electron transfer between transition metal ions and facilitating the formation of numerous oxygen vacancies. This feature is advantageous for the reversible production and breakdown of discharge product Li2O2. Consequently, the Li‐O2 battery utilizing LS(MFCCN)O3 as a catalyst achieves an impressive discharge capacity of 17,078.2 mAh g−1 and exhibits an extended cycling life of 435 cycles. This study offers a useful method for adjusting the catalytic performance of perovskite oxides toward oxygen redox reactions in Li‐O2 batteries.

Published: January 2024

AbstractThe development of precious‐metal‐free catalysts with bifunctional activities for both oxygen reduction and evolution reactions (ORR/OER) is crucial for the advancement of regenerative fuel cells and rechargeable metal−air batteries. Manganese oxides (MnOx) have emerged as promising bifunctional catalysts. However, MnOx electrodes typically exhibit poor ORR/OER cycling stability owing to polarization‐induced MnOx redox reactions and phase transition. To address this issue, we developed metallic cation (i. e., Co2+, Ni2+, Cu2+, or Bi3+) doped MnOx/carbon electrodes using potentiodynamic, potentiostatic and galvanostatic methods. Among the explored dopant cations Ni2+ intercalated into MnOx under acidic conditions using a slow‐scan cyclic voltammetry method, significantly enhanced the ORR/OER activity and stability of MnOx. Alongside electrochemical doping, MnOx also underwent redox reactions leading to changes in Mn valence and phase transitions. The Ni‐incorporated MnOx gas diffusion electrode (GDE) demonstrated exceptional stability for over 120 accelerated OER and ORR cycles at ±10 mA cm−2 in 5 M KOH, surpassing the performance of the Pt/C−IrO2 benchmark. Furthermore, it achieved OER current densities of approximately 22 mA cm−2 at 1.65 VRHE, which was twice as high as that of Pt/C−IrO2.
