Photomultiplication Enabling High‐Performance Narrowband Near‐Infrared Organic Photodetectors
Authors: Winkler Louis Conrad , Kublitski Jonas , Benduhn Johannes , Leo Karl 
Published: May 2023

AbstractContinuous monitoring of food quality, blood oxygen, or industrial processes require high‐throughput near‐infrared photodetectors. Due to excellent properties like low‐cost fabrication, flexibility and narrowband response, organic photodetectors (OPDs) have a huge market potential for such applications. An organic donor–acceptor blend with a low‐energy and broad charge transfer (CT) feature is utilized, circumventing the difficulties of obtaining organic materials with significant absorption beyond 1000 nm. The increasing recombination of such low‐energy gap materials that is detrimental for the quantum efficiency is overcome by applying two photocurrent multiplication (PM) mechanisms to the donor–acceptor blend. Combined with an optical micro‐cavity, this OPD achieves a spectral response (SR) of 15 A W−1 at 1092 nm. With its spectrally narrow response of only 18 nm, this OPD technology can be used for highly resolved measurements. Contrary to OPDs working in the photovoltaic mode, this detector is optimized for operation under reverse bias. With its high spectral response, low‐cost readout circuitry like CMOS can be used for signal detection.

AbstractThe prevalent global energy crisis calls for searching viable pathways for generating green hydrogen as an alternative energy resource. Dye‐sensitized photocatalytic water splitting is a feasible solution to produce green hydrogen. However, identifying suitable catalysts has been one of the bottlenecks in driving dye‐sensitized photocatalysis efficiently. In this work, a new class of electrocatalysts is reported based on the layered Weyl semimetals MIrTe4 (M = Nb, Ta) for the Eosin Y (EY)‐sensitized hydrogen evolution reaction (HER). NbIrTe4 and TaIrTe4 exhibit HER activities of ≈18 000 and 14 000 µmol g−1 respectively, after 10 h of irradiation with visible light. Time‐dependent UV‐Vis spectroscopy and high‐pressure liquid chromatography coupled with mass spectrometry analysis shed light on the reaction dynamics and enable a deeper understanding of the observed trend in hydrogen evolution rates for MIrTe4. MIrTe4 semimetals outperform transition metal‐based Weyl semimetals in terms of catalytic HER activity using EY as photosensitizer and triethanolamine as the sacrificial agent. It is hypothesized that the topology‐related band inversion in MIrTe4 Weyl semimetals promotes a high density of M d‐states near the Fermi level, driving their high catalytic performance. This study introduces a new class of layered Weyl semimetals as efficient catalysts, and provides perspectives for designing topology‐enhanced catalysts.
A New Chromone‐based Sequential Functioning Colorimetric Chemosensor for Cu2+ and Cysteine in Near‐perfect Aqueous Media

Published: May 2023

AbstractA selective chromone‐containing colorimetric chemosensor DOCC ((E)‐N,N‐dimethyl‐2‐((4‐oxo‐4H‐chromen‐3‐yl)methylene)hydr azine‐1‐carbothioamide) was designed for the sequential probing of Cu2+ and cysteine. DOCC exhibited a marked color variation from colorless to pale yellow and had the lowest limit of detection (0.30 μM) among the chromone‐based colorimetric sensors for Cu2+ in near‐perfect aqueous media. DOCC could work to probe and quantify Cu2+ in real water samples with great recovery (98‐102%). DOCC could discriminate Cu2+ using the test kit down to 10 μM. On the other hand, Cu2+‐2⋅DOCC could selectively detect cysteine (Cys) in a sequential step through the demetallation reaction. Cu2+‐2⋅DOCC showed that its color returned from pale yellow to colorless only in the presence of Cys and its limit of detection was calculated to be 6.62 μM. The practical applications for Cys were successfully achieved in water samples with perfect recovery (99–100%) and pH tests at 7–9. FT‐IR, Job plot, ESI‐MS, and DFT calculations were applied to explain the sensing mechanisms of Cu2+ by DOCC and Cys by Cu2+‐2⋅DOCC.

AbstractThe metabolic reprogramming of tumors requires high levels of adenosine triphosphate (ATP) to maintain therapeutic resistance, posing a major challenge for photothermal therapy (PTT). Although raising the temperature helps in tumor ablation, it frequently leads to severe side effects. Therefore, improving the therapeutic response and promoting healing are critical considerations in the development of PTT. Here, we proposed a gas‐mediated energy remodeling strategy to improve mild PTT efficacy while minimizing side effects. In the proof‐of‐concept study, a Food and Drug Administration (FDA)‐approved drug‐based hydrogen sulfide (H2S) donor was developed to provide a sustained supply of H2S to tumor sites, serving as an adjuvant to PTT. This approach proved to be highly effective in disrupting the mitochondrial respiratory chain, inhibiting ATP generation, and reducing the overexpression of heat shock protein 90 (HSP90), which ultimately amplified the therapeutic outcome. With the ability to reverse tumor thermotolerance, this strategy delivered a greatly potent antitumor response, achieving complete tumor ablation in a single treatment while minimizing harm to healthy tissues. Thus, it holds great promise to be a universal solution for overcoming the limitations of PTT and may serve as a valuable paradigm for the future clinical translation of photothermal nanoagents.

AbstractCobalt ferrite (CoFe2O4) spinel has been found to produce C2−C4 hydrocarbons in a single‐step, ambient‐pressure, photocatalytic hydrogenation of CO2 with a rate of 1.1 mmol g−1 h−1, selectivity of 29.8 % and conversion yield of 12.9 %. On stream the CoFe2O4 reconstructs to a CoFe−CoFe2O4 alloy‐spinel nanocomposite which facilitates the light‐assisted transformation of CO2 to CO and hydrogenation of the CO to C2−C4 hydrocarbons. Promising results obtained from a laboratory demonstrator bode well for the development of a solar hydrocarbon pilot refinery.

AbstractAnode‐free lithium (Li) metal batteries are desirable candidates in pursuit of high‐energy‐density batteries. However, their poor cycling performances originated from the unsatisfactory reversibility of Li plating/stripping remains a grand challenge. Here we show a facile and scalable approach to produce high‐performing anode‐free Li metal batteries using a bioinspired and ultrathin (250 nm) interphase layer comprised of triethylamine germanate. The derived tertiary amine and LixGe alloy showed enhanced adsorption energy that significantly promoted Li‐ion adsorption, nucleation and deposition, contributing to a reversible expansion/shrinkage process upon Li plating/stripping. Impressive Li plating/stripping Coulombic efficiencies (CEs) of ≈99.3 % were achieved for 250 cycles in Li/Cu cells. In addition, the anode‐free LiFePO4 full batteries demonstrated maximal energy and power densities of 527 Wh kg−1 and 1554 W kg−1, respectively, and remarkable cycling stability (over 250 cycles with an average CE of 99.4 %) at a practical areal capacity of ≈3 mAh cm−2, the highest among state‐of‐the‐art anode‐free LiFePO4 batteries. Our ultrathin and respirable interphase layer presents a promising way to fully unlock large‐scale production of anode‐free batteries.

Published: May 2023

AbstractEnantioselective synthesis of N−N biaryl atropisomers is an emerging area but remains underexplored. The development of efficient synthesis of N−N biaryl atropisomers is in great demand. Herein, the construction of N−N biaryl atropisomers through iridium‐catalyzed asymmetric C−H alkylation is reported for the first time. In the presence of readily available Ir precursor and Xyl‐BINAP, a variety of axially chiral molecules based on indole‐pyrrole skeleton were obtained in good yields (up to 98 %) with excellent enantioselectivity (up to 99 % ee). In addition, N−N bispyrrole atropisomers could also be synthesized in excellent yields and enantioselectivity. This method features perfect atom economy, wide substrate scope, and multifunctionalized products allowing diverse transformations.

AbstractA three‐component synthesis methodology is described for the formation of covalent organic frameworks (COFs) containing extended aromatics. Notably, this approach enables synthesis of the building blocks and COF along parallel reaction landscapes, on a similar timeframe. The use of fragmental building block components, namely pyrene dione diboronic acid as aggregation‐inducing COF precursor and the diamines o‐phenylenediamine (Ph), 2,3‐diaminonaphthalene (Naph), or (1R,2R)‐(+)‐1,2‐diphenylethylenediamine (2Ph) as extending functionalization units in conjunction with 2,3,6,7,10,11‐hexahydroxytriphenylene, resulted in the formation of the corresponding pyrene‐fused azaacene, i.e., Aza‐COF series with full conversion of the dione moiety, long‐range order, and high surface area. In addition, the novel three‐component synthesis was successfully applied to produce highly crystalline, oriented thin films of the Aza‐COFs with nanostructured surfaces on various substrates. The Aza‐COFs exhibit light absorption maxima in the blue spectral region, and each Aza‐COF presents a distinct photoluminescence profile. Transient absorption measurements of Aza‐Ph‐ and Aza‐Naph‐COFs suggest ultrafast relaxation dynamics of excited‐states within these COFs.

Published: May 2023

AbstractHighly‐active and low‐cost bifunctional electrocatalysts for oxygen reduction and evolution are essential in rechargeable metal‐air batteries, and single atom catalysts with Fe−N−C are promising candidates. However, the activity still needs to be boosted, and the origination of spin‐related oxygen catalytic performance is still uncertain. Herein, an effective strategy to regulate local spin state of Fe−N−C through manipulating crystal field and magnetic field is proposed. The spin state of atomic Fe can be regulated from low spin to intermediate spin and to high spin. The cavitation of dxz and dyz orbitals of high spin FeIII can optimize the O2 adsorption and promote the rate‐determining step (*O2 to *OOH). Benefiting from these merits, the high spin Fe−N−C electrocatalyst displays the highest oxygen electrocatalytic activities. Furthermore, the high spin Fe−N−C‐based rechargeable zinc‐air battery displays a high power density of 170 mW cm−2 and good stability.

AbstractDual‐atom catalysts (DAC) are deemed as promising electrocatalysts due to the abundant active sites and adjustable electronic structure, but the fabrication of well‐defined DAC is still full of challenges. Herein, bonded Fe dual‐atom catalysts (Fe2DAC) with Fe2N6C8O2 configuration were developed through one‐step carbonization of a preorganized covalent organic framework with bimetallic Fe chelation sites (Fe2COF). The transition from Fe2COF to Fe2DAC involved the dissociation of the nanoparticles and the capture of atoms by carbon defects. Benefitting from the optimized d‐band center and enhanced adsorption of OOH* intermediates, Fe2DAC exhibited outstanding oxygen reduction activity with a half‐wave potential of 0.898 V vs. RHE. This work will guide more fabrication of dual‐atom and even cluster catalysts from preorganized COF in the future.

AbstractDeep sodium extraction/insertion of sodium cathodes usually causes undesired Jahn–Teller distortion and phase transition, both of which will reduce structural stability and lead to poor long‐cycle reliability. Here we report a zero‐strain P2‐ Na2/3Li1/6Co1/6Mn2/3O2 cathode, in which the lithium/cobalt substitution contributes to reinforcing the host structure by reducing the Mn3+/Mn4+ redox, mitigating the Jahn–Teller distortion, and minimizing the lattice change. 94.5 % of Na+ in the unit structure can be reversibly cycled with a charge cut‐off voltage of 4.5 V (vs. Na+/Na). Impressively, a solid‐solution reaction without phase transitions is realized upon deep sodium (de)intercalation, which poses a minimal volume deviation of 0.53 %. It attains a high discharge capacity of 178 mAh g−1, a high energy density of 534 Wh kg−1, and excellent capacity retention of 95.8 % at 1 C after 250 cycles.

Published: May 2023

AbstractIn this paper, the formation consensus problem for a class of leader–follower networked multi‐agent systems under communication constraints and switching topologies is investigated. A networked predictive control scheme is proposed to achieve stability and output formation consensus with the switching topology, capable of compensating for data loss and time delays in the network. By equating the whole closed‐loop networked multi‐agent system with the proposed control scheme to the corresponding switched system, the sufficient and necessary condition of output formation consensus and stability for agents is given. Finally, using three‐degree‐of‐freedom air‐bearing spacecraft simulators as the control objects, the proposed scheme is demonstrated to be able to actively compensate for the communication constraints through numerical simulations, and it is also verified to have a good control performance by further realizing the formation task of the simulators through practical experiments.

AbstractPsoriasis is an immune‐mediated inflammatory skin disease driven by interleukin‐17A (IL‐17A) and associated with cardiovascular dysfunction. We used a severe psoriasis mouse model of keratinocyte IL‐17A overexpression (K14‐IL‐17Aind/+, IL‐17Aind/+ control mice) to investigate the activity of neutrophils and a potential cellular interconnection between skin and vasculature. Levels of dermal reactive oxygen species (ROS) and their release by neutrophils were measured by lucigenin‐/luminol‐based assays, respectively. Quantitative RT‐PCR determined neutrophilic activity and inflammation‐related markers in skin and aorta. To track skin‐derived immune cells, we used PhAM‐K14‐IL‐17Aind/+ mice allowing us to mark all cells in the skin by photoconversion of a fluorescent protein to analyze their migration into spleen, aorta, and lymph nodes by flow cytometry. Compared to controls, K14‐IL‐17Aind/+ mice exhibited elevated ROS levels in the skin and a higher neutrophilic oxidative burst accompanied by the upregulation of several activation markers. In line with these results psoriatic mice displayed elevated expression of genes involved in neutrophil migration (e.g., Cxcl2 and S100a9) in skin and aorta. However, no direct immune cell migration from the psoriatic skin into the aortic vessel wall was observed. Neutrophils of psoriatic mice showed an activated phenotype, but no direct cellular migration from the skin to the vasculature was observed. This suggests that highly active vasculature‐invading neutrophils must originate directly from the bone marrow. Hence, the skin‐vasculature crosstalk in psoriasis is most likely based on the systemic effects of the autoimmune skin disease, emphasizing the importance of a systemic therapeutic approach for psoriasis patients.
On the Role of N‐Heterocyclic Carbene Salts in Alkyl Radical Generation from Alkyl Alcohols: A Computational Study

Published: May 2023

AbstractFormation of carbon‐carbon bonds through cross‐coupling reactions using readily available substrates, like alcohols, is crucial for modern organic chemistry. Recently, direct alkyl alcohol functionalization has been achieved by the use of N‐Heterocyclic Carbene (NHC) salts via in situ formation of an alcohol‐NHC adduct and its activation by a photoredox catalyst to generate carbon‐centered alkyl radicals. Experimentally, only electron deficient NHC activators work but the reasons of this behavior remain underexplored. Herein, a DFT computational study of the mechanism of alcohol activation using up to seven NHC salts is performed to shed light into the influence of their electronic properties in the alkyl radical formation. This study demonstrates that four reaction steps are involved in the transformation and characterizes how the electronic properties of the NHC salt affect each step. A fine balance of the NHC electron‐richness is proved to be determinant for this transformation.
Comparative analysis of structural modifications induced by monocular retinal inactivation and monocular deprivation in the developing cat lateral geniculate nucleus

Published: May 2023

AbstractDuring a critical period of postnatal life, monocular deprivation (MD) by eyelid closure reduces the size of neurons in layers of the dorsal lateral geniculate nucleus (dLGN) connected to the deprived eye and shifts cortical ocular dominance in favor of the non‐deprived eye. Temporary inactivation of the non‐deprived eye can promote superior recovery from the effects of long‐term MD compared to conventional occlusion therapy. In the current study, we assessed the modification of neuron size in the dLGN as a means of measuring the impact of a brief period of monocular inactivation (MI) imposed at different postnatal ages. The biggest impact of MI was observed when it occurred at the peak of the critical period. Unlike the effect of MD, structural plasticity following MI was observed in both the binocular and monocular segments of the dLGN. With increasing age, the capacity for inactivation to alter postsynaptic cell size diminished but was still significant beyond the critical period. In comparison to MD, inactivation produced effects that were about double in magnitude and exhibited efficacy at older ages. Notwithstanding the large neural alterations precipitated by MI, its effects were remediated with a short period of binocular experience, and vision through the previously inactivated eye fully recovered. These results demonstrate that MI is a potent means of modifying the visual pathway and does so at ages when occlusion is ineffective. The efficacy and longevity of inactivation to elicit plasticity highlight its potential to ameliorate disorders of the visual system such as amblyopia.
Multifunctional materials with controllable superwettability for oil–water separation and removal of pollutants: Design, emerging applications, and challenges
Authors: Wang Yiwen , Wang Wenbo 
Published: May 2023

AbstractThe water pollution problem caused by large‐scale industrial activity is becoming increasingly serious, which not only poses a major threat to the ecosystem and human health but also seriously impedes the green and sustainable development of modern society. It is urgent to efficiently purify stubborn wastewater containing oils and other pollutants to eliminate their harm to human and environment. Therefore, it is desirable to develop multifunctional materials that can simultaneously remove oil and various pollutants or microorganisms by filtration or absorption methods to meet the practical demand for highly effective purification of wastewater with complex components. This paper summarizes the latest research progress on the “oil removal” and “water removal” materials capable of purifying complex oily wastewater and their applications in adsorption, photocatalytic degradation, antibacterial, magnetic recovery, and others. The producing routes of multifunctional materials by constructing variable wettability surfaces and introducing functional components were summarized, and the mechanism of multifunctional materials in removing oil and various pollutants was discussed. On the basis of summarizing the types, compositions, and conventional separation technologies of oil‐bearing wastewater, the preparation methods and applications of the widely concerned convertible materials with complex wettability are also introduced, and the challenges and future development trends of efficient multifunctional oil–water separation and pollutant purification materials are proposed. It is expected to provide a reference for the development of more high‐performance multifunctional purification materials.
