Authors: Huang Tiansheng , Sun Li‐Peng , Li Xiangping , Guan Bai‐Ou 
Published: December 2024

AbstractDespite the great success in deploying metal‐organic frameworks (MOFs) as efficient electrocatalysts, the low adoption of operando methods hinders the understanding of underlying mechanism. By leveraging the subtle refractive index evolution, including both the real and the imaginary parts, an entirely new concept of a lab‐on‐fiber operando method and its feasibility for “pristine‐immersion‐operando‐post analysis” of electrocatalyts are demonstrated. Concurrent collection of absorption spectra and surface plasmon resonance is achieved by engineering fiber‐optic waveguides to simultaneously induce guided light attenuation and plasmonic coupling. In situ‐formed Co hydroxide and oxide reactive intermediates in zeolitic imidazolate framework‐67 (ZIF‐67) electrocatalyst are optically identified, which shows its underlying self‐reconstruction conversions at different stages during electrocatalytic oxygen evolution reactions, and address the gap in knowledge concerning whether ZIF‐67 is a precatalyst for real catalyst production. This illuminating operando method offers intriguing opportunities to collect all the observables in a single fiber, provides an exciting potential of a new class of device with long‐sought integration and miniaturization capability, and is expected to enable the electrocatalysis community to conquer challenges with conducting multimodal operando experiments outside the laboratory.

AbstractThe rapid increase in lithium‐ion battery (LIB) production, fueled by the rise of electric vehicles, highlights significant challenges in managing end‐of‐life LIBs, particularly regarding environmental impact and waste management. Traditional recycling methods, such as pyrometallurgical and hydrometallurgical processes, are energy‐intensive and consume substantial reagents. In this study, a laser‐assisted regeneration method is introduced for LiMn2O4 (LMO) cathodes, enabling in situ Ni doping into spent LMO cathodes (r‐LMO‐Ni) to enhance electrochemical performance. Surface Ni‐doping improves interfacial processes and reduces capacity loss at lower temperatures by creating a new interface with a lower charge transfer energy barrier. The r‐LMO‐Ni cathode surpasses pristine LMO cathodes, achieving a specific capacity of 112.95 mA h g−1 at 1 C and retaining 95.1% of its capacity after 200 cycles at 0 °C. A techno‐economic analysis supports the feasibility of this laser‐assisted regeneration approach, offering an innovative pathway for upcycling spent cathodes and developing next‐generation Mn‐based cathodes.
Sustainable Recovery of Rare Earth Metals from Smartphone Display using Nanoengineered Cellulose

Published: December 2024

AbstractRecycling rare earth elements (REEs) from electronic waste has gained significant attention over the last decade. A sustainable, fast, and selective extraction technique for rare earth metals hardly exists despite that. This work shows a selective rare earth metal recovery from a mobile phone display using a carboxylate functionalized cellulose (CFC). The nanoengineered CFC is water‐dispersible and prepared from affordable, readily available cellulose precursor. It is shown that the REEs present in the mobile phone display instantaneously form a precipitate with CFC, which is easily separated by centrifugation. As low as 150 ppm, the total concentration of REEs in the leachate is required to form a precipitate. The total removal capacity of the REEs in the leachate is 252 ± 4 mg per gram of CFC. In addition, the precipitate formation occurs within 10 s, which to our knowledge, is the best‐reported removal time so far. It is observed that when the total concentration of the REEs in the leachate is 150 ppm or above, the removal capacity of CFC is quite efficacious and unperturbed by the presence of other metal ions. Solar electrodeposition method is utilized to recover rare earth metal and their oxide from the precipitate.

Published: December 2024

AbstractTraditionally, Rayleigh scattering is thought to only impact fiber sensing system performance when the leading fiber is over 10 km long. However, this report illustrates theoretically and experimentally that Rayleigh scattering cannot be ignored in fiber optic interferometric sensor (FOIS) even with several hundred‐meter common leading fiber because of the interaction of Rayleigh backward scattering (RBS) and returning interference signal. Herein, a conceptual framework is developed to elucidate the interaction between RBS and FOIS interference, revealing that, beyond laser monochromacity, the self‐correction characteristic of laser pulses also influences coherent superposition. Building upon this novel insight, a phase modulation method based on pseudorandom noise (PRN) code is first proposed to address coherent RBS stacking on returning FOIS interferences while preserving high laser monochromacity. By modulating the interrogation pulses, a 21.3 dB suppression of background phase noise is achieved in FOIS with 3.3 km leading fiber. This study offers a holistic understanding of Rayleigh scattering in the leading fiber, encompassing experimental observations, theoretical modeling, physics analysis, and its resolution, thereby contributing to advancements in underwater sensing to broaden the understanding of the underwater environment.

Published: December 2024

AbstractThe development of polydimethylsiloxane (PDMS) graphene composites with high graphene content, employed to formulate printing ink for the fabrication of tunable multilayer pressure sensors via 3D printing is presented. This study demonstrates an efficient preparation technique capable of incorporating a high loading of edge‐functionalized expanded graphene into PDMS while minimally affecting the inherent crosslinking properties of the matrix. Graphene addition enhances electrical conductivity and rheological investigations reveal improves the printability of PDMS. Three sensor configurations differing in layer order and conductivity through piezoresistive characterization, demonstrating their excellent sensitivity and tunability with a gauge factor of ≈20 are evaluated. This performance is comparable to, and in some cases exceeds, similar structures reported in the literature. The assessment of the real‐world application potential of the PDMS/graphene pressure sensor in monitoring human movements during typical everyday situations reveals promising results. These findings suggest that the sensors developed here hold significant promise for diverse pressure‐sensing applications across various fields, including wearables, medical diagnostics, and industrial automation

Published: December 2024

AbstractBiosensors based on field effect transistor (FET), also known as Bio‐FETs, offer numerous advantages, including high sensitivity, rapid response speed, low operating voltage, compact size, high reliability, and easily integrative. These features endow Bio‐FETs with tremendous performance in rapid analysis for samples with ultra‐low concentration at large‐scale, broadening their multiple potential applications. In recent years, the research based on Bio‐FETs has attracted more and more attention. A lot of effort is put into the challenge to improve their sensitivity, which can be influenced by various factors. This review focuses on the current approaches from multiple perspectives, including overcoming the influence of Debye shielding effects, promoting the binding efficiency of analytes and FETs surface, and improving the structures of FETs device. Correspondingly, novel strategies to increase the Debye length, facilitate high frequency electric field modulation, enhance the specific interaction efficiency, and enlarge the specific surface area (SBET) are also summarized. Additionally, there is a lack of a reliable standard method to characterize the sensitivity of FETs currently. Regarding this issue, the most commonly used definitions and representation parameters of sensitivity are also evaluated. Overall, this review outlines the potential future research directions to offer insights for enhancing the sensitivity of Bio‐FETs.

Published: December 2024

AbstractVanadium oxide‐based materials are considered to be among the most promising positive electrode candidates for aqueous zinc‐metal batteries (AZMBs). However, complex processes, high costs, and insufficient yields of their preparation methods limit further application. Herein, an efficient and effective oil bath method is presented for the preparation of CaV6O16·2.7H2O (CaVO), offering promising performance as cathode material for AZMBs. With commercial crystalline V2O5, Ca(CH3COO)2, and water as raw materials, phase‐pure CaVO with 42.8 g per batch and a yield of 98.8% can be obtained through the reaction at 90 °C for 6 h. It is further demonstrated that the pre‐intercalated Ca2+ and H2O not only expand the interlayer spacing from 4.38 Å for V2O5 to 8.21 Å for CaVO but also stabilize the interlayer structure of vanadium oxides, promoting the reversibility of CaVO toward the de‐/intercalation of Zn2+/H+. In addition, density‐functional theory calculations show that the introduction of Ca2+ and H2O effectively improves the diffusion kinetics of Zn2+ in CaVO. As a result, CaVO provides high specific capacity (379 mAh g−1 at 0.05 A g−1) and promising long‐term cyclability (94.4% capacity retention after 2200 cycles at 1 A g−1), demonstrating the efficient and effective synthesis of vanadium oxide‐based cathode materials for high‐performance AZMBs.

Published: December 2024

AbstractIn this work, 44 metal–organic frameworks (MOFs) are screened for efficient electrocatalytic nitrogen reduction reaction (eNRR). The isosteric heats of N2 adsorption on the 44 metal active centers of MOFs are calculated by the grand canonical Monte Carlo method. It is found that p‐block‐elements exhibit the highest N2 affinity among all screened elements, implying their excellent catalytic potentials for eNRR. Furthermore, the Al element is preferentially chosen as the metal center of MOFs (MIL‐53 (Al)) owing to its relatively low toxicity and cost. Combined in situ Diffuse Reflectance Infrared Fourier Transform (DRIFT) analysis with theoretical calculation, we found that N2 is mainly attracted by the bridging oxygen of Al‐O‐Al structure in the MIL‐53 (Al). The optimized MIL‐53 (Al) shows a superior activity with the NH3 yield rate of 74.55 ± 1 μg h−1 mgcat−1 at −0.3 V vs. Reversible Hydrogen Electrode (RHE), to our best knowledge, which is currently the highest activity of MOF‐based catalyst for eNRR reported in the literature.

AbstractOne of the most significant challenges of luminescent materials is the thermal quenching (TQ) at high temperature. Understanding the correlation between crystal structure variation and photoluminescence (PL) quenching is significant to achieve anti‐thermal quenching (anti‐TQ) phosphors. Herein, we unveil a universal principle governing switchable TQ and anti‐TQ behaviors in zero‐dimensional (0D) organic–inorganic hybrid manganese bromides. We observed an abnormal anti‐TQ phenomenon when phosphor is excited in the valley of PL excitation (PLE) spectrum (indirect excitation) while TQ phenomenon is observed when excited in the peak and shoulder positions of PLE. Our findings demonstrate that PL intensity is influenced by two variable parameters: the effective Mn‐ligand distance and the shortest Mn−Mn distance. These excitation‐dependent TQ and anti‐TQ behaviors originate from the relative changes in these distances, which modulate the competition between radiative and nonradiative recombination rates, as evidenced at the molecular level by molecular dynamics simulation. X‐ray activated radioluminescence (RL) also exhibits anti‐TQ behavior, which is analogous to the indirect excitation of PL evolution when excited at PLE valley. These insights bridge the gap between PL and RL properties in 0D manganese halides and offer potential avenues for developing advanced anti‐TQ phosphors, efficient LEDs, and high‐performance scintillators.

AbstractAmong the various challenges in the field of organic light‐emitting diodes (OLEDs), simultaneously achieving high efficiency, a long lifespan, and a narrow full‐width at half maximum (FWHM) in blue OLEDs remains a significant hurdle. Herein, we demonstrate a strategy to improve the color purity of tetradentate Pt(II) complexes with the assistance of ⋅⋅⋅H interaction by incorporating trifluoromethyl (−CF3) groups into the well‐known blue tetradentate Pt(II) phosphorescent complex. The results show that the different substitution positions of −CF3 have significantly varying effects on the FWHM values of the complexes; specifically, introducing −CF3 on the benzene ring of carbazole effectively reduces the FWHM, while introducing it on the benzene ring linked to the carbene unit has a minimal impact. When utilized in a mixed host system of SiCzCz/SiTrzCz2, the OLEDs with these new complexes as emitters demonstrated maximum external quantum efficiencies (EQEs) of 27.1 %, 33.8 %, and 27.6 % for PtON‐CF3‐1, PtON‐CF3‐2, and PtON‐2CF3, respectively, with excellent color purity (CIEy≈0.14 for the PtON‐CF3‐2 based device). Notably, the device based on PtON‐CF3‐2 matched the stability of the benchmark PtON‐TBBI complex.This work offers an important guideline for the design of high efficient Pt(II) phosphorescent complexes with good blue color purity.
A Possible but Elusive Mutuality: Psychoanalysis and Blackness
Authors: Adams C. Jama 
Published: December 2024

ABSTRACTPsychoanalysis writ large, has enriched Black lives, but not as a result of the activities of a mostly culturally indifferent institutional psychoanalysis. In its unceasing attempts to pursue a good‐enough life, within the obstacles of a racist structure, elements of the Black community have both adopted and offered psychoanalytic‐themed perspectives in such attempts. This offer the possibility of informing a re‐imagining of a staid, and increasingly irrelevant mainstream clinical psychoanalysis.

Published: December 2024

AbstractA charge‐density‐wave (CDW) is characterized by a dynamical order parameter consisting of a time‐dependent amplitude and phase, which manifest as optically‐active collective modes of the CDW phase. Studying the behavior of such collective modes in the time‐domain, and their coupling with electronic and lattice order, provides important insight into the underlying mechanisms behind CDW formation. This work reports on femtosecond broadband transient reflectivity experiments of bulk 1T‐VSe2 using near‐infrared excitation. At low temperature, coherent oscillations associated with the CDW amplitude mode and phonons of the distorted lattice are observed. Across the expected transition temperature at 110 K, signatures of a rearrangement of the electronic structure are evident in the quasiparticle dynamics. However, the amplitude mode instead softens to zero frequency at 80 K, possibly indicating an additional phase transition at this temperature. In addition, photoinduced CDW melting, associated with a collapse of the electronic and lattice order, is found to occur at moderate excitation densities, consistent with a dominant electron‐phonon CDW mechanism.
Organisational Anomie: A Qualitative Study on Homecare Workers' Experiences of Work and Organisational Normative Structure

Published: December 2024

ABSTRACTThe organisational environment and work design dramatically influence employees' performance, wellbeing and identity. However, little is known about how organisational normative structure – that is, the set of general values and shared norms that regulate individuals' behaviours in a community or an organisation – influences employees experiences and wellbeing. We apply the concept of anomie to explore how Norwegian homecare workers (HCWs) experience their working environment, the normative structure of their organisation and its influence on their performance, wellbeing and identity. We examine organisational anomie in terms of perceptions of a discrepancy between job demands, various expectations and job resources as well as a discrepancy between one's normative ideals of care and the organisational work design to fulfil the caring duties and obligations. We conducted a qualitative interview study, recruiting 10 HCWs in Norway. Using reflexive thematic analysis, we developed the following five major themes to describe HCWs' understanding of their working environment and its influence: (1) The only sure thing is that anything can happen, (2) Multiple affordances of home as a context for care, (3) Conflict between normative beliefs and the organisational working environment, (4) Time pressure affects presence and (5) Did I do a good enough job? We discuss these themes with regard to their practical implications for the homecare institution and the theoretical implications for extending anomie theories to the organisational context.

ABSTRACTThe Verbascum genus has gained significant attention in the pharmaceutical field, particularly in recent years, due to its valuable medicinal properties, which are well‐recognized in complementary and alternative medicine. Certain species within this genus contain essential compounds and exhibit a wide range of therapeutic activities. In this study, the ethanolic extract of Verbascum gimgimense (VG) was analyzed for its cytotoxic, apoptotic, antioxidant, and enzyme inhibitory properties, as well as its phenolic and lipophilic compounds. The phenolic compounds in the extract were identified using Exactive Plus Orbitrap HPLC‐HRMS, while the lipophilic components were characterized by GC‐MS analysis. The Neutral Red Uptake (NRU) cell viability assay and colony formation assay were performed to assess the antiproliferative and anti‐colony survival effects of VG on the A549 human lung adenocarcinoma cell line. Additionally, a wound healing assay measured cell migration, and the apoptotic process was evaluated using Caspase‐3 ELISA and acridine orange/ethidium bromide staining. Protein expression levels were determined by western blot analysis. DPPH, ABTS FRAP, and CUPRAC assays were used to determine free radical scavenging, reducing power, and metal chelating activities, respectively. VG was rich in dominant phenolic components, including benzoic acid (6.809 mg/g extract), phloretic acid (1.279 mg/g extract), luteolin 7‐rutinoside (2.799 mg/g extract), luteoloside (3.300 mg/g extract), kuromanine (3.456 mg/g extract), and rutin hydrate (2.015 mg/g extract). Major fatty acids identified in VG included palmitic acid (17.3%), stearic acid (2.99%), linoleic acid (9.44%), and α‐linolenic acid (26.48%). VG treatment significantly reduced colony formation ability, decreased wound closure, and increased both apoptotic cell count and caspase‐3 activity compared to the control group. Protein levels of c‐PARP, p53, and p21 were substantially elevated compared to controls. In addition to its strong free radical scavenging, reducing power and metal chelating activity, VG exhibited strong inhibitory effects on α‐amylase, α‐glucosidase, AChE, BChE, and tyrosinase. Our study demonstrates that VG possesses antiproliferative, apoptotic, antioxidant, and enzyme‐inhibitory properties. V. gimgimense emerges as a promising natural antioxidant source with potentially significant regulatory effects on key enzymes and proteins, which could contribute to managing various human diseases and inspire the development of novel therapeutic strategies.

Published: December 2024

ABSTRACTMeralgia paresthetica (MP) is an entrapment syndrome of the lateral femoral cutaneous nerve characterized by tingling, numbness, itching and burning pain, and dysesthesia in anterolateral aspect of thigh. In this case report, we present a 37‐year‐old non‐obese female with 2‐month history of progressive pain and tingling on the anterolateral side of right thigh. Clinical features of patient were consistent with MP, which was confirmed via electrodiagnostic study. Subsequent abdominopelvic and transvaginal sonography revealed a mass‐like lesion measuring 92 × 61 mm in right adnexa adjacent to the right ovary. Following diagnosis, the patient underwent cystectomy, resulting in immediate resolution of symptoms. This case highlights the importance of comprehensive evaluation in patients presenting with MP symptoms, including consideration of abdominopelvic pathology as a potential contributing factor.
