Published: November 2024

AbstractNanofluidic memristors have recently been reshaped into artificial synapses capable of mimicking many fundamental neurosynaptic patterns, while sense digitalization has been increasingly explored to link the neuromorphic devices with external equipment. By inspiration of dopaminergic nerve, here a nanofluidic nerve with sense digitalization is devised by engineering a dopamine (DA)‐specific nanofluidic synapse as mediated by PC‐12 cells to manage the robotic arm. Different from previous neuromorphic perception of DA via redox reaction, the aptamer‐based perception here is based on biological DA recognition by its receptor as indicated by the ionic signals. Various neurosynaptic patterns are emulated with DA‐dependent plasticity, based on which the digital representation of DA perception is used to control the robotic arm.

Published: November 2024

AbstractElectronic defect states in catalysts are recognized as highly effective active sites for enhancing the low‐concentration electroreduction of NO to NH3 (NORR). Their structures dynamically evolve with applied electrode potentials, allowing the active sites to adjust interactions with intermediates, thereby improving electrocatalytic performance. However, the dynamic changes in these interactions under applied potentials remain poorly understood, hindering the design of more diverse electrocatalytic systems. Herein, we developed a strategy that unitizes electrode potential to control the interactions between active sites and intermediates over oxygen vacancy‐modified TiO2 (VO−TiO2−x) to enhance NORR performance. By combining state‐of‐the‐art constant inner potential (CIP) DFT calculations with in situ (spectro)electrochemical measurements, we investigated how the electrode potential influences these interactions in NORR. The results clearly demonstrate that applying an external potential alters the spatial symmetry of degenerate orbitals of Ti3+ to facilitate the generation of key intermediates for NO‐to‐NH3 conversion. Therefore, the VO−TiO2−x catalyst exhibited superior NORR performance with a NH3 Faradaic efficiency up to 76.4 % and a high NH3 yield rate of 632.9 μg h−1 mgcat.−1 under 1.0 vol % NO atmosphere, which is competitive with those of previously reported works under higher NO concentration (above 10 vol %). Remarkably, the NORR process achieved a record‐breaking NH3 yield of 2292.7 μg h−1 mgcat.−1 in a membrane electrode assembly (MEA) electrolyzer under the same conditions. This study opens a new avenue for enhancing electrocatalytic activity by adjusting operating conditions, thereby transcending the limitations of material design.

Published: November 2024

AbstractSingle pack epoxy adhesives, known for their simple operation process, combined with good reactivity at moderate temperatures and excellent storage stability, have gained extensive attention. An appropriate accelerator is crucial for enhancing their performance. This study demonstrates that the zinc zeolitic imidazolate framework ZIF‐8 (Zn(2‐methylimidazole)2) can effectively serve as an effective accelerator for the epoxy‐anhydride system, as evidenced by the complete exothermic curing curve obtained via differential scanning calorimetry (DSC) tests of the epoxy (A‐128) and anhydride (THPA) adhesive sample with ZIF‐8. The optimal addition amount of ZIF‐8 (0.9%) was determined by assessing the glass transition temperature (Tg) of the cured resin with varying ZIF‐8 weight fractions. Furthermore, the ideal curing conditions—gel temperature of 388.4 K, curing temperature of 416.7 K, and post‐treatment temperature of 441.9 K—were established by analyzing heating curves at different circumstances. The epoxy (A‐128) and anhydride (THPA) system with accelerator ZIF‐8 exhibited superior stability compared to the commercial accelerators like PN‐23 or DMP‐30. This is attributed to the steric hindrance and coordination bonds of ZIF‐8, indicated by a large pre‐exponential factor (A1 = 5.58 × 108) and low‐value reaction rate constant (k1 = 0.3461 × 10−3 s−1). In addition, the kinetic parameters, and an autocatalytic equation model for the epoxy (A‐128) and anhydride (THPA) system with accelerator ZIF‐8 have been derived through isothermal curing kinetics analysis.

Published: November 2024

ABSTRACTPolypropylene (PP) based nanocomposites with graphitic carbon nitride nanosheets (CNNSs) exfoliated from g‐C3N4 (CN) were fabricated via melt compounding. The detailed structure and morphology of the CNNSs were examined using X‐ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscope (TEM), and atomic force microscopy (AFM) measurements. The effects of CNNSs on the crystalline morphology, oxygen vapor permeability, and mechanical properties of PP based nanocomposites were carefully evaluated. The CNNS not only increased the crystallization peak temperature and crystallinity, but also enhanced gas barrier properties and tensile strength of the PP nanocomposites. For PP/CNNS‐2 nanocomposites, the tensile strength was increased by 10.7%, and oxygen permeability coefficients decreased by 64.5% compared to pure PP. Therefore, PP/CNNS nanocomposite could be a potential candidate for packing application.
Racism as ontological terror and onticide
Authors: Piven Jerry S. 
Published: November 2024

AbstractThis paper elucidates the existential and psychological dynamics of onticide: the malicious annihilation of another's existential‐emotional being. On any given day, chances are we're going to read a new account of racist violence and injustice that is, simply put, grotesque. This cannot be adequately explained as mere ignorance or prejudice. An existential phenomenology of racism is needed to explain that disgust, malice, and disdain. What arouses such fear, hatred, loathing, and the desire to punish or humiliate? This paper explores the ways in which inner impoverishment and wounds are turned into fantasies of evil in the outer world, and how the ontological dread of annihilation and nonbeing induce the desire to harm, diminish, and annihilate the menacing other.
New Data on the Distribution of Sperm Whales in the Western Mediterranean Highlights Insufficiency of Currently Proposed Protection Measures

Published: November 2024

ABSTRACTAs part of ongoing efforts to protect marine megafauna, especially cetaceans, in the NW Mediterranean Sea, a ‘Particularly Sensitive Sea Area’ (PSSA) was established in July 2023 by the governments of France, Italy, Spain and Monaco through the Marine Environment Protection Committee (MEPC) of the International Maritime Organisation (IMO). This is a legal instrument by which maritime traffic can be subject to advisories or controls to protect the natural environment. While the new PSSA is a significant step forward in terms of marine wildlife protection in the region, the current area only partially includes the waters that play a key ecological role for the conservation of Mediterranean sperm whales (Physeter macrocephalus) around the Balearics Archipelago. This isolated population is currently classified as endangered by the IUCN. Survey data from 2019 to 2022 show how the current area does not include portions of habitat in which calves are more likely to be encountered and risks displacing any maritime traffic that chooses to avoid the voluntary PSSA restrictions into habitat that is sensitive for calf survival. We argue therefore that this PSSA should be augmented to incorporate waters that are an important habitat for this endangered population.

Published: November 2024

AbstractThe proliferation of lithium dendrites has long posed a formidable hurdle in the widespread adoption of lithium metal batteries, thereby necessitating the urgent resolution of how to effectively mitigate their growth as the paramount challenge in the realm of energy storage. Herein, we have crafted a novel sandwich‐structured current collector comprising an ethylene‐vinyl acetate polymer (EVA)/Cu2O/Cu configuration, where the EVA thin film acts as a protective barrier, passivating the lithium metal anode, while the Cu2O layer fosters lithiophilic sites conducive to uniform lithium nucleation. Our experiments reveal that the EVA thin film adeptly prevents direct contact and subsequent reactions between the lithium metal and the electrolyte, enhancing the ion mobility of Li+ ions, ultimately leading to a even distribution of lithium deposition. In a Li−Cu half‐cell, the incorporation of the EVA film increases the nucleation potentials but dramatically reduces polarization potentials after 50 cycles of charge‐discharge processes. Remarkably, the Li−Cu half‐cells equipped with EVA‐coated current collectors exhibit lower electrochemical resistances, translating into significantly extended cycle lives. This work indicates the sandwich architecture (thin film/lithium metal/lithiophilic compounds) is a promising contender for achieving long‐lasting, stable lithium anodes.
Biomass‐Derived Materials in Perovskite Solar Cells: Recent Progress and Future Prospects
Authors: Rahman Md. Mahbubur , Woong Kim Tae 
Published: November 2024

AbstractAs a promising photovoltaic (PV) technology, perovskite solar cells (PSCs) have made significant progress in attaining high PCE, while challenges remain regarding stability and low cost. Conventional PSCs using noble metals (e. g., Au and Ag) as back electrodes and transparent conducting oxides as front electrodes contribute significantly to their high costs. PSCs comprising biomass‐derived materials, such as biocarbon as back electrodes and flexible and transparent cellulosic substrates as front electrodes, offer a promising solution to address these issues. These approaches have the potential to simultaneously improve stability and decrease manufacturing costs, making PSCs closer to commercialization. This review article furnishes a comprehensive overview of recent developments in biocarbon‐based perovskite solar cells (C‐PSCs), focusing on various biomass‐derived biocarbon materials utilized as back electrodes in different C‐PSCs device structures. This article also compiles the advancement of flexible and transparent cellulosic substrate‐based PSCs by highlighting the fundamentals of PSC and C‐PSC architectures, the basics of biomass, and the synthesis of biocarbon. Finally, this review discusses the current challenges and future research directions for optimizing biocarbon materials and cellulosic substrates in PSC technology.

Published: November 2024

AbstractAn efficient Mn(III)‐promoted phosphorylation of dehydroalanine (Dha) has been developed to give unusual α‐amino acids bearing phosphonates/phosphine oxides and β‐vinyl phosphonates/phosphinates depending on N‐protection of amino acid. N,N‐diprotected dehydroalanine reacted with H‐phosphonates and H‐phosphine oxides to give structurally diverse phosphorylated α‐amino acids through conjugate addition of phosphorous radical generated by Mn(OAc)3.2H2O. Whereas, a highly Z‐selective phosphorylation was observed in the case of mono N‐Boc protected dehydroalanine via cross dehydrogenative coupling to give (Z)‐ β ‐vinyl phosphono amino acid. The method is successfully applied to short peptides to derive unusual phosphono‐peptides under mild conditions.

Published: November 2024

AbstractThe germylamine Ph3GeN(SiMe3)2 was synthesized from Ph3GeCl and LiN(SiMe)2 and its X‐ray crystal structure was determined. This structure represents only the fourth crystallographically characterized germylamine that has been reported. The two sterically encumbering −SiMe3 groups completely encapsulate the germanium‐nitrogen bond and the geometry at the nitrogen atoms is trigonal planar rather than pyramidal. The structure of Ph3GeN(SiMe3)2 was calculated using density functional theory and it was found that the HOMO of this molecule is stabilized relative to that of Ph3GeNMe2, which has been shown to be a highly effective reagent for the amidation of acid fluorides. The steric attributes Ph3GeN(SiMe3)2, coupled with its more stable HOMO relative to Ph3GeNMe2, prevent its functioning as an amidation reagent for acid fluorides except in the case of benzoyl fluoride.
Clients' narratives of healing and harm in psychotherapy: A qualitative method
Authors: Tavallaei Seyed Vahid , Najarpourian Samaneh , Rastegar Yaser 
Published: November 2024

AbstractPurposeFor decades, researchers have acknowledged the potential for negative effects in psychotherapy, highlighting the need for further investigation. However, a clear understanding of the nature and definition of harm within this context has remained elusive. Efforts were made to clarify terminology such as ‘side effects’ and ‘negative effects’, but a consensus on the extent and definition of harm has continued to evade the field. Notably, existing research on negative effects has often prioritised expert and therapist perspectives, neglecting the crucial insights offered by the client's subjective experience of harm.MethodThis study adopted an exploratory approach, employing qualitative research methods. To uncover and illuminate past experiences of harm within the therapeutic context, semi‐structured interviews were conducted with 21 participants (15 female, 6 male) who reported perceiving their psychotherapy sessions as harmful. Data analysis utilised the theoretical framework of Strauss and Corbin's grounded theory approach, facilitated by the MAXQDA2020 software.ResultsThe study results offered a comprehensive examination of factors contributing to client‐perceived harm in psychotherapy, categorised as both client‐related and therapist‐related. Additionally, the definition of harm was explored through the lens of emotional and cognitive experiences. The client's reaction to perceived harm (submission, avoidance and compensation) and the therapist's course of action vs. the client's reaction (corrective and justifying) respectively, can cause consequences (strengthening the therapeutic alliance and the client's healing or individual and interpersonal impacts) from the client's perspective.ConclusionA significant finding was the lack of attention paid to the interpersonal nature of psychotherapy in past understandings of harm. The results highlight the potential for harm in any therapeutic relationship, regardless of the therapist. This potential appears to be particularly heightened when therapists display a lack of responsiveness to clients' internal experiences, especially through justifying comments in response to client‐reported negative experiences within the therapeutic relationship. Based on these findings, the study offers clinical recommendations for therapists to enhance their responsiveness and mitigate potential harm.
A Photo‐Caged Cross‐Linker for Identifying Protein‐Protein Interactions
Authors: Chen Xingyu , Jiménez López Cristina , Nadler André , Stengel Florian 
Published: November 2024

AbstractCross‐linking mass spectrometry (XL–MS) has seen significant improvements which have enhanced its utility for studying protein‐protein interactions (PPIs), primarily due to the emergence of novel crosslinkers and the development of streamlined analysis workflows. Nevertheless, poor membrane permeability and side reactions with water limit the extent of productive intracellular crosslinking events that can be achieved with current crosslinkers. To address these problems, we have synthesized a novel crosslinker with o‐nitrobenzyl‐based photoresponsive groups. These o‐nitrobenzyl ester (o‐NBE) groups enhance the stability and hydrophobic properties of the crosslinker and add the potential for temporal resolution, i. e. the ability to control the initiation of the crosslinking reaction. Upon exposure to UV light the resulting aldehyde product reacts with adjacent amino groups and subsequent reductive amination of the formed Schiff‐bases yields stable secondary amine linkages. This controlled activation mechanism enables precise UV‐triggered protein crosslinking. We demonstrate proof‐of principle of our o‐NBE cross‐linker to reliably detect PPIs by XL–MS using a recombinant model protein. We also demonstrate its ability to enter intact Hela cells, thereby indicating its future potential as a useful tool to study PPIs within the cellular environment.

Published: November 2024

AbstractPeroxidases belong to a group of enzymes that are widely found in animals, plants and microorganisms. These enzymes are effective biocatalysts for a wide range of oxidations on various substrates. This work presents a biochemical and structural characterization of a novel heme‐containing peroxidase from Cyanobacterium sp. TDX16, CyanoPOX. This cyanobacterial enzyme was successfully overexpressed in Escherichia coli as a soluble, heme‐containing monomeric enzyme. Although CyanoPOX shares relatively low sequence identity (37 %) with bovine lactoperoxidase, it displays comparable biochemical properties. CyanoPOX is most stable and active in slightly acidic conditions (pH 6–6.5) and moderately thermostable (melting temperature around 48 °C). Several compounds that are typical substrates for mammalian lactoperoxidases were tested to establish the catalytic potential of CyanoPOX. Potassium iodide showed the highest catalytic efficiency (126 mM−1 s−1), while various aromatic compounds were also readily converted. Structural elucidation of CyanoPOX confirmed the presence of a non‐covalently bound b‐type heme cofactor that is situated in the central core of the protein. Except for a highly similar overall structure, CyanoPOX also has a conserved active site pocket when compared with mammalian lactoperoxidases. Due to its catalytic properties and high expression in a bacterial host, this newly discovered peroxidase shows promise for applications.

ABSTRACTBackgroundTranscatheter valve‐in‐valve (VIV) or valve‐in‐ring (VIR) therapies for degenerated mitral bioprosthetic valves and rings are still evolving. We aimed to characterize short‐ and long‐term outcomes of these procedures.MethodsAn electronic literature search was conducted to retrieve articles describing mitral VIV or VIR implantation with at least 10 patients. Meta‐analysis of proportions was carried out for 30‐day or in‐hospital outcomes of mortality, stroke, major bleeding, transfusion, acute kidney injury, procedural success, valve embolization, paravalvular leak, pacemaker implantation, and hospital stay. Individual patient data meta‐analysis using Kaplan‐Meier curve reconstruction was used to estimate long‐term mortality of VIV, VIR and redo surgical mitral valve replacement (SMVR).ResultsWe analyzed 34 studies (7047 patients). Pooled procedural success was 94.8% in VIV and 80.5% in VIR. Pooled short‐term mortality and stroke risk was 6.4% and 1.9% respectively in VIV, 9.1% and 1.6% respectively in VIR, and 8.4% and 5.5% respectively in SMVR.ConclusionsThis study provides prognostic information on clinical outcomes for redo SMVR and transcatheter mitral VIV and VIR implantation.

ABSTRACTAn 80‐year‐old man presented to our hospital with worsening renal function and ambulation difficulties due to lower extremity symptoms that included livedo reticularis, gangrene, cyanosis, and ulcers in his legs. The patient was diagnosed with a cholesterol crystal embolism. Treatment with prednisolone and rosuvastatin was initiated; however, no improvements were observed in the patient's cutaneous symptoms or renal function. Therefore, we decided to treat the patient with a new low‐density lipoprotein apheresis device (Rheocarna; Kaneka Corporation, Osaka, Japan). Following therapy, the lower extremity symptoms improved, and although dialysis was temporarily initiated, it was eventually discontinued.

AbstractThe potassium aluminyl K[Al(NON)] ([NON]2−=[O(SiMe2NDipp)2]2−, Dipp=2,6‐iPr2C6H3) reacts with group 14 chloroamidinates E{14}(Am)Cl (E{14}=Ge, Sn, Pb. [Am]−=[tBuC(NDipp)2]−) to form (NON)Al−E{14}(Am) Lewis pairs with unsupported Al−E{14} bonds, including the first structurally authenticated Al−Pb bond. Analysis using spectroscopic (NMR, UV‐vis and Mössbauer for E{14}=Sn), X‐ray diffraction and computational (DFT, QTAIM, TD‐DFT) methods conclude an Al−E{14} σ‐bond derived from a Lewis basic Al and a Lewis acidic tetrylene, with back‐donation from the E{14} s‐orbital lone pair donor NBO to acceptor NBOs on Al that are derived from s/p‐orbitals. The reaction of the Al−Ge compound with CO2 forms the dioxocarbene (NON)Al(μ‐O2C)Ge(Am), whilst under the same conditions the Al−Sn compound reacts with additional CO2 to form the carbonate, (NON)Al(μ‐CO3)Sn(Am). Addition of ethene to the Al−E{14} (E{14}=Ge, Sn) compounds introduces an ethylene bridge between the aluminium and group 14 atoms forming a frustrated Lewis pair (FLP). Reaction of the (Al/Ge) FLP with CO2 forms an activation product with new Al−O and Ge−C bonds, whilst reaction with iPrN=C=NiPr proceeds with insertion into the Al−C bond to form an aluminium amidinate.
