AbstractLaser initiation has attracted increasing interest owing to its extraordinary safety and high reliability. However, traditional metal complex‐based laser‐ignitable primary explosives are limited by high input laser energy and low detonation ability. In this study, an efficient laser‐ignitable primary explosive‐based copper azide is prepared by constructing core‐shell hetero‐framework Cu‐MOF@COF as the precursor. The pyrolysis of Cu‐MOF@COF hybrid material affords copper azide (CA) nanoparticle confined in a porous carbon shell, referred to CA@C Shell. The evenly coated porous carbon shell functions as light‐to‐heat conversion layer efficiently promoting the laser initiation process of inside CA. Consequently, CA@C Shell can be initiated at lower laser energy thresholds (0.80 mJ at 1064 nm). This value is significantly lower than typical laser ignitable metal complex tetraamine‐cis‐bis(5‐nitro‐2H‐tetrazolato‐N2)cobalt(III)perchlorate (726 mJ at 808 nm). Moreover, the CA@C Shell successfully detonates the secondary explosives CL‐20 by laser energy when it is assembled in a micro‐detonator system. This study offers a unique method for constructing high performance laser‐ignitable primary explosives for micro‐detonator applications.

AbstractSingle‐atom catalysts (SACs) exhibit unparalleled atomic utilization and catalytic efficiency, yet it is challenging to modulate SACs with highly dispersed single‐atoms, mesopores, and well‐regulated coordination environment simultaneously and ultimately maximize their catalytic efficiency. Here, a generalized strategy to construct highly active ferric‐centered SACs (Fe‐SACs) is developed successfully via a biomineralization strategy that enables the homogeneous encapsulation of metalloproteins within metal–organic frameworks (MOFs) followed by pyrolysis. The results demonstrate that the constructed metalloprotein‐MOF‐templated Fe‐SACs achieve up to 23‐fold and 47‐fold higher activity compared to those using metal ions as the single‐atom source and those with large mesopores induced by Zn evaporation, respectively, as well as up to a 25‐fold and 1900‐fold higher catalytic efficiency compared to natural enzymes and natural‐enzyme‐immobilized MOFs. Furthermore, this strategy can be generalized to a variety of metal‐containing metalloproteins and enzymes. The enhanced catalytic activity of Fe‐SACs benefits from the highly dispersed atoms, mesopores, as well as the regulated coordination environment of single‐atom active sites induced by metalloproteins. Furthermore, the developed Fe‐SACs act as an excellent and effective therapeutic platform for suppressing tumor cell growth. This work advances the development of highly efficient SACs using metalloproteins‐MOFs as a template with diverse biotechnological applications.

Published: September 2022

AbstractCurrent technologies for the real‐time analysis of biomarkers in vivo, such as needle‐type microelectrodes and molecular imaging methods based on exogenous contrast agents, are still facing great challenges in either invasive detection or lack of active control of the imaging probes. In this study, by combining the design concepts of needle‐type microelectrodes and the fluorescence imaging method, a new technique is developed for detecting biomarkers in vivo, named as “optically controlled virtual microsensor” (OCViM). OCViM is established by the organic integration of a specially shaped laser beam and fluorescent nanoprobe, which serve as the virtual handle and sensor tip, respectively. The laser beam can trap and manipulate the nanoprobe in a programmable manner, and meanwhile excite it to generate fluorescence emission for biosensing. On this basis, fully active control of the nanoprobe is achieved noninvasively in vivo, and multipoint detection can be realized at sub‐micrometer resolution by shifting a nanoprobe among multiple positions. By using OCViM, the overexpression and heterogenous distribution of biomarkers in the thrombus is studied in living zebrafish, which is further utilized for the evaluation of antithrombotic drugs. OCViM may provide a powerful tool for the mechanism study of thrombus progression and the evaluation of antithrombotic drugs.

Published: September 2022

Abstractα‐RuCl3 is a candidate material for the realization of a Kitaev spin liquid with envisioned applications for quantum computing. It is a van‐der‐Waals material with in‐plane honeycomb lattice equivalent to the CrX3 (X= Cl, Br, I) type 2D magnets. Here, possibilities of defect engineering and surface modification of thin crystals are explored by Ar+ dosing and vacuum annealing. Chlorine is easily removed from the surface, which reduces the Ru valence and eventually leaves a Ru rich surface layer behind. A peculiar thickness dependence of the work function emerges after Ar+ sputtering, which is ascribed to the remaining chlorine concentration. This work elucidates material properties of thin α‐RuCl3 and introduces concepts of property engineering to create homojunctions and control level alignment by standard in situ methods.

AbstractA dome‐shaped phase diagram of superconducting critical temperature upon doping is often considered as a hallmark of unconventional superconductors. This behavior, observed in SrTiO3‐based interfaces, whose electronic density is controlled by field‐effect, has not been explained unambiguously yet. Here, a generic scenario for the superconducting phase diagram of these oxide interfaces is elaborated based on transport experiments on a double‐gate LaAlO3/SrTiO3 field‐effect device and Schrödinger–Poisson numerical simulations of the quantum well. The optimal doping point of maximum Tc is ascribed to the transition between a single‐gap and a fragile two‐gap s±‐wave superconducting state involving bands of different orbital character. Close to this point, a bifurcation in the dependence of Tc on the carrier density, which can be controlled by the details of the doping execution, is observed experimentally and reproduced by numerical simulations. Where doping with a back‐gate triggers the filling of a new subband and initiates the overdoped regime, doping with a top‐gate delays the filling of the subband and maintains the 2D electron gaz in the single‐gap state of higher Tc. Such a bifurcation, whose branches can be followed reversibly, provides a generic explanation for the dome‐shaped superconducting phase diagram that could be extended to other multiband superconducting materials.

AbstractGraphene plasmonic structures can support enhanced and localized light–mater interactions within extremely small mode volumes. However, the external quantum efficiency of the resulting devices is fundamentally limited by material scattering and radiation loss. Here, such radiation loss channels are suppressed by tailoring the structure to support a symmetry‐protected bound‐state‐in‐the‐continuum (BIC) system. With practical loss rates and doping level in graphene, over 90% absorption near critical coupling is expected from numerical simulation. Experimentally measured peak absorption of 68% is achieved in such a tailored graphene photonic–plasmonic system, with maximum 50% contrast to the control sample without graphene. Significant reduction of the plasmon absorption for a different spacer thickness verifies the sensitivity of the system to the quasi‐BIC condition.

AbstractNear‐infrared phosphor‐converted light‐emitting diodes (NIR pc‐LEDs) are promising for many applications in non‐destructive testing, bio‐imaging, and modern agriculture. However, developing self‐activated NIR phosphors with high efficiency and excellent thermal stability is a great challenge for current research. In this work, a self‐activated far‐red to NIR emitting NaLaMgWO6 phosphor is prepared by the high‐temperature solid‐state reaction method, whose luminescence properties are investigated in detail. In addition, the introduction of Bi3+ ions as sensitizers enhances the emission intensity of far‐red to NIR light (650‐850 nm) through a Bi3+ → WO66– energy transfer design strategy, resulting in an increased internal quantum efficiency (IQE) from 56.4% to 64.8% and thermal stability from 54% to 72% (420 K). Finally, the combination of NaLaMgWO6:Bi3+ with 365/460 nm commercial LED chip is prepared into NIR pc‐LED devices, demonstrating satisfactory performance in the field of night vision detection and other wide range of practical applications.

AbstractThe investigations on the relationship between geometrical structures, excited state properties, and photophysical performance can accelerate the design of thermally activated delayed fluorescence (TADF) molecules. Herein, the photophysical properties of newly proposed organic TADF molecule: [4‐(9,9‐dimethyl‐9,10‐dihydroacridine) phenyl] (pyridin‐4‐yl)‐methanone (PyB‐DMAC), are theoretically investigated by using the quantum mechanics and molecular mechanics method. The photophysical performance dependency of PyB‐DMAC molecule on its geometrical and electronic structures, and aggregation effects are systematically analyzed. The calculated fluorescence quantum efficiencies are in good agreement with the experimental results, for instance, the calculated fluorescence efficiency of 61.2% (exp. 49%) for PyB‐DMAC molecule in the crystal phase. Based on these investigations, novel organic TADF molecules can be designed by balancing the singlet–triplet energy gap (ΔEST) and transition dipole moment. Sixteen unexplored candidates are screened with similar structures to PyB‐DMAC molecule, while two new TADF organic molecules (PyBF‐DMAC and OSOF‐DMAC) are selected with enhanced luminescence performance. The newly designed TADF molecules reveal lower reorganization energies and reduced nonradiative decay rates. The simulation results exhibit that their luminescence quantum efficiencies in toluene solvent and amorphous state are as high as 63.7%, 53.2% and 90%, 97.4%, respectively.

AbstractResistive random‐access memories are promising candidates for novel computer architectures such as in‐memory computing, multilevel data storage, and neuromorphics. Their working principle is based on electrically stimulated materials changes that allow access to two (digital), multiple (multilevel), or quasi‐continuous (analog) resistive states. However, the stochastic nature of forming and switching the conductive pathway involves complex atomistic defect configurations resulting in considerable variability. This paper reveals that the intricate interplay of 0D and 2D defects can be engineered to achieve reproducible and controlled low‐voltage formation of conducting filaments. The author find that the orientation of grain boundaries in polycrystalline HfOxis directly related to the required forming voltage of the conducting filaments, unravelling a neglected origin of variability. Based on the realistic atomic structure of grain boundaries obtained from ultra‐high resolution imaging combined with first‐principles calculations including local strain, this paper shows how oxygen vacancy segregation energies and the associated electronic states in the vicinity of the Fermi level govern the formation of conductive pathways in memristive devices. These findings are applicable to non‐amorphous valence change filamentary type memristive device. The results demonstrate that a fundamental atomistic understanding of defect chemistry is pivotal to design memristors as key element of future electronics.

AbstractA major challenge to overcome in demonstrating solid oxide fuel cells (SOFCs) to be suitable as efficient and environmentally friendly energy conversion devices capable of addressing pressing clean energy and environmental needs is to surmount chemical and thermo‐mechanical instabilities in their operational phase. To date, perovskite‐based mixed conducting cathodes, which include inherent Co and Sr elements for enhanced reactivity and conductivity, have been intensively studied. These Co/Sr‐based oxides, however, exhibit severe thermochemical expansion and suffer from Sr surface segregation, ultimately degrading the electrode performance. Here, high‐performance and durable SOFCs are demonstrated by employing a Co/Sr‐free fluorite‐based mixed conducting (Pr,Ce)O2‐δ (PCO) cathode eminently compatible with fluorite‐based solid electrolytes. The nanocolumnar PCO electrode developed in this study provides not only a remarkable low level of electrode resistance (e.g., ≈0.05 Ω cm2 at 600 °C) but also exceptional long‐term stability (e.g., a degradation rate 15 times slower compared to the state‐of‐the‐art La0.6Sr0.4CoO3‐δ perovskite). The competitive peak power densities of an anode‐supported single cell with the PCO cathode are also successively achieved, recording a value of 0.92 W cm−2 at 600 °C. These findings herald the development of new Co/Sr‐free electrodes for SOFCs at intermediate temperatures.
Understanding pulse oximetry in hematology patients: Hemoglobinopathies, racial differences, and beyond
Authors: Patterson Sarah , Sandercock Nick , Verhovsek Madeleine 
Published: September 2022

AbstractPulse oximetry (SpO2) is a widely used, non‐invasive method of estimating arterial oxygen saturation. Measurement of SpO2 relies on comparing the relative absorption of light in the red and infrared regions with the expected absorption pattern of oxygenated and deoxygenation adult hemoglobin. As this screening tool has entered common clinical use, test limitations have emerged, including concern about the risk of overestimation of oxygen saturation by pulse oximetry in a disproportionate number of people with dark skin pigment, leading to potential for underdiagnosis of true hypoxemia. In addition, a range of challenges may arise in patients with increased levels of methemoglobin – whether acquired or inherited – carboxyhemoglobin, or in patients with a subset of inherited variant hemoglobins. It is important for Hematologists, and indeed all clinicians who rely on pulse oximetry, to understand the principles and limitations of this ubiquitous test.

Two new Cu(II) complexes [Cu2(L)2(mb)](ClO4)·0.5H2O (1) and [Cu4(L)4(sq)(H2O)2](ClO4)2·2H2O (2) (HL = 2‐[(2‐morpholine‐4‐yl‐ethylimino)‐methyl]‐phenol); mb = 4‐methyl benzoate; sq2− = C4O42− squarate dianion) have been synthesized and characterized by single crystal X‐ray analysis, electrospray ionization mass spectrometry, and infrared spectroscopic technique. The structural determination showed the Schiff base acting as tridentate ligand coordinating the copper(II) atoms by the phenoxo, imino and morpholine nitrogen donors to give comparable Cu(L) entities in both complexes 1 and 2. Complex 1 is a dinuclear cationic species built by a 4‐methylbenzoate anion coordinating two Cu(L) moieties. The two Cu(II) centers are chemically equivalent exhibiting a distorted square pyramidal geometry. Complex 2 is tetranuclear and it is formed by a centrosymmetric squarate core connected to four Cu(L) complex units to give a cationic complex counterbalanced by perchlorate anions. Of the two independent Cu(II) atoms, Cu1 exhibits a square pyramidal coordination sphere, whereas Cu2 is better described as square planar. The crystal packing of complex 2 shows a polymeric arrangement through H‐bonding. Magnetic measurements show antiferromagnetic coupling in both the complexes. The interaction of complexes with hen egg lysozyme has been investigated by using UV–vis absorption and 2D/3D fluorescence spectroscopic techniques and the calculated values of binding constants, Kbin, are (5.9 ± 0.11) × 104, (17.39 ± 0.04) × 104, and (10.1 ± 0.07) × 104 M−1 for HL, 1, and 2, respectively.

Published: September 2022

AbstractWhile there is a considerable amount of interest in information and communication technologies for development (ICT4D) in the Indigenous communities, it remains limited to those who can afford it and have the skills and knowledge to implement the technology and access appropriate digital tools. Hence, Indigenous communities are continually stigmatized as marginalized, leading to a cultural misrepresentation of histories that affects the continuing information disparity between Indigenous and Western knowledge systems, particularly the insufficient technology infrastructure designed for traditional users. In this article, ICT4D was conceptualized as a digital platform to support Senior Ngarrindjeri Elder Aunty Ellen Trevorrow in continuing her practice of weaving and storytelling throughout the pandemic. In this context, the community‐based participatory research (CBPR) principles within the structure of video ethnography were qualitatively designed to implement the ICT4D project culturally and ethically. Video recordings, image data, transcriptions, and the Ngarrindjeri ICT4D Pondi (Murray Cod) framework were embedded to justify the findings and the aim of illustrating Aunty Ellen's knowledge‐sharing process to online learners. Likewise, the results demonstrate the positive and negative impact of COVID‐19 on the continuity and orality of Aunty Ellen's cultural stories and practices. The future continuity of Aunty Ellen's knowledge ought to consider the inconsistency of technological infrastructure in regional areas, her waning health, and the interconnectedness of oral expertise, which often pose challenges. This study is a small step toward a better understanding of the value of oral knowledge; emphasizing the creation of e‐learning weaving instructional videos is valuable for future digital management of Indigenous knowledge relevant to LIS.

Published: September 2022

AbstractImidazole represents a fascinating class of explosophoric units with exciting structures and unique properties. As compared to other nitrogen‐rich heterocycles, imidazole demonstrates great potential applications due to economic effectiveness and superior energetic performances. The field of traditional chemistry has been extensively explored for imidazole, and thus established bond‐building methods and functionalization strategies promote further development as high‐energy density materials (HEDMs). This review addresses the development of energetic imidazole compounds in the past decade, summarizes their physiochemical properties, and is divided into three parts (explosives, propellants, and energetic biocides) according to application requirements. Various synthetic strategies for these energetic molecules are highlighted, including the construction of heterocyclic frameworks and following functionalization. The selected and discussed reactions illustrate the versatility of imidazole in energetic applications as building blocks for the future design of new HEDMs.
