Temperature/pH dual-responsive reversible morphology evolution of block copolymer microparticles under three-dimensional confinement

Development of block copolymer (BCP) microparticles with switchable morphology in response to external stimuli is important for exploiting new intelligent materials. In this work, thermo/pH dual-responsive nanoparticles (NPs) were employed as a cosurfactant to modulate the self-assembly morphology of polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) microparticles within confined emulsion droplets. The co-surfactant was synthesized by grafting poly(acrylic acid)-b-poly(N-isopropylacrylamide) onto the surface of Fe_3O_4 NP. The introduction of the dual-responsive co-surfactant enabled thermo/pH dual-responsive reversible morphology transition of the PS-b-P2VP microparticles by tailoring the hydrophobicity and interfacial affinity of the cosurfactant. By using this strategy, the thermo-inert PS-b-P2VP self-assembled into pupa-like microparticles at T = 10 °C and pH 7.5, which could transform into tulip-like microparticles when T was increased to 50 °C. When the pH value was increased to 11, the pupa-like particles turned into onion-like microparticles although the PS-b-P2VP was inert to alkali. However, the pupa-like microparticles remained unchanged when both T and pH were simultaneously increased. The PAA-b-PNIPAM-grafted Fe_3O_4 NP surfactants showed obvious advantages over the linear PAA-b-PNIPAM surfactants in modulating the morphology transition, since the linear PAA-b-PNIPAM could not induce the reversible shape transition of microparticles. Our work provides an efficient strategy to achieve reversible shape transformation of BCP microparticles while the internal phase structure is preserved, which may be utilized to switch the structural color properties of BCP microparticles.
Rising from the dead: the power of genome editing

To protect themselves against diverse pathogens, plants have developed sophisticated defense mechanisms. Hypersensitive response or the rapid localized death of plant cells is a major defense strategy deployed by plants to kill the invading pathogens (Wu et al., 2014). In the last several decades, scientists have identified many mutants that form lesions on leaves in the absence of infections due to misregulation of cell death. These mutants are classified as lesion mimic mutants (LMMs) (Kang et al., 2021). LMMs often confer broad-spectrum disease resistance. However, due to spontaneous cell death, these LMMs frequently come with severely reduced crop yield.
High-density stacked microcoils integrated microminiaturized electromagnetic vibration energy harvester for self-powered acceleration sensing

With the rapid development of microelectronics and flexible electronics technology, self-powered sensors have significant application prospects in human-machine interface systems and Internet of Things. However, piezoelectric- and triboelectricbased sensors have low current output and are easily affected, while electromagnetic-based sensors are difficult to miniaturize. This work proposes a high-density stacked microcoil integrated microminiaturized electromagnetic vibration energy harvester(EVEH). The double-layer high-density microcoil is fabricated on both sides of the flexible polyimide substrate interconnected via the central through-hole. Owing to reduced single coil line width, line spacing, and stacked structure, the number of turns can be substantially enhanced. Moreover, the relative position of the coils and magnet has a considerable influence on the performances; due to the huge change rate in magnetic flux when the coil is placed in the radial direction of the magnet than in the axial direction, the open-circuit voltage in the radial direction is 10 times greater. The microcoil can maintain good performance at high, low temperatures and under bending conditions. When the distance between the ends of the coil changes from 2 to 20 mm in 2 mm steps, the bending angle of the coil changes from 45° to 270° in 45° steps; furthermore, when the coil is exposed to -40 and 60°C conditions, the coil resistance is maintained at approximately 447 Ω. The peak open-circuit voltage of three-piece microcoils reaches 0.41 V at 4 Hz under 2g, and the output voltage and current increase with an increasing number of stacked layers. These excellent properties indicate that EVEH can be used for self-powered acceleration sensing. The sensitivity is measured to be 0.016 V/(m/s~2)with a correlation coefficient of 0.979 over the acceleration range of 1-18 m/s~2. Thus, the developed microminiaturized EVEH has enormous potential for self-powered sensing applications in confined spaces and harsh environments.
Hadron productions and jet substructures associated with Z~0/γ in Pb+Pb collisions at the LHC

We carry out a detailed study of medium modifications on Z~0/γ+hadron correlations as well as jet substructures in association with Z~0/γ in Pb+Pb collisions with √s_(NN)= 5.02 TeV at the LHC. We utilize the linear Boltzmann transport(LBT)model to simulate the jet-medium interactions and medium response, and an extended cluster hadronization model to investigate the nonperturbative transition of quarks and gluons into final hadrons in heavy-ion collisions. Including hadronization effect, we can well describe Z~0/γ+hadrons correlations and Z~0/γ-tagged jet substructures in both p+p and Pb+Pb collisions simultaneously. Medium modification on jet profile and jet fragmentation functions indicate that particles carrying a large fraction of the jet momentum are generally closely aligned with the jet axis, whereas low-momentum particles are observed to have a much broader angular distribution relative to jet axis in Pb+Pb collisions due to jet-medium interactions. In particular, we find that Z~0/γ-tagged hadron correlations are sensitive to the soft particles from the dense medium and medium response, while jet-substructures show weak dependence on those soft hadrons with only a fraction of them falling inside the jet area.
Challenges and approaches of single-crystal Ni-rich layered cathodes in lithium batteries

High energy density and high safety are incompatible with each other in a lithium battery, which challenges today’s energy storage and power applications. Ni-rich layered transition metal oxides (NMCs) have been identified as the primary cathode candidate for powering next-generation electric vehicles and have been extensively studied in the last two decades, leading to the fast growth of their market share, including both polycrystalline and single-crystal NMCcathodes. Single-crystal NMCs appear to be superior to polycrystalline NMCs, especially at low Ni content (≤60%). However, Ni-rich single-crystal NMC cathodes experience even faster capacity decay than polycrystalline NMC cathodes, rendering them unsuitable for practical application. Accordingly, this work will systematically review the attenuation mechanism of single-crystal NMCs and generate fresh insights into valuable research pathways. This perspective will provide a direction for the development of Ni-rich single-crystal NMCcathodes.
Design guidance for improved organic solar cells: both from materials and devices

With the huge consumption of traditional fossil energy and the consequent environmental and economic pressure, the development of a new energy that is cheap, green and rich has become an urgent issue for human society. Solar energy is a kind of abundant green renewable energy, and the technology of solar cells that can convert solar energy into electric energy is one of the effective ways to solve the energy and environmental crisis. Compared with traditional silicon-based inorganic solar cells commonly used in commercial, organic solar cells (OSCs) have the advantages of low cost, light weight, strong flexibility, and diverse processing methods. Since the OSCs have great application potential in clothing, architecture, aerospace, environmental protection and other fields, they have been widely concerned and studied in recent years.
Investigation and mitigation of Mott neuronal oscillation fluctuation in spiking neural network

Mott devices, featuring low hardware cost and high energy efficiency, have been demonstrated as a key oscillatory element in artificial neurons to enable spiking neural networks (SNNs) such as conversionbased SNNs (CSNNs). However, there will be inevitably non-ideal fluctuation in the oscillation behavior, causing the accuracy degradation of networks. In this paper, we investigate the Mott neuronal oscillation fluctuation (NOF) through experiments and modeling. The results show that the NOF phenomenon conforms to Gaussian distribution and originates from thermal fluctuation induced switching voltage variations. We construct a two-layer CSNN for image recognition tasks to study the NOF effect and propose the activation function boundary (AFB) method to strengthen the stability of the network. The results indicate that AFB can improve the accuracy of CSNN by up to 15.5% by tightening output distribution.
End-group modulation of phenazine based non-fullerene acceptors for efficient organic solar cells with high open-circuit voltage

Phenazine-based non-fullerene acceptors (NFAs) have demonstrated great potential in improving the power conversion efficiency (PCE) of organic solar cells (OSCs).Halogenation is known to be an effective strategy for increasing optical absorption,refining energy levels,and improving molecular packing in organic semiconductors.Herein,a series of NFAs (PzIC-4H,PzIC-4F,PzIC-4Cl,PzIC-2Br) with phenazine as the central core and with/without halogen-substituted (dicyanomethylidene)-indan-1-one (IC) as the electron-accepting end group were synthesized,and the effect of end group matched phenazine central unit on the photovoltaic performance was systematically studied.Synergetic photophysical and morphological analyses revealed that the PM6:PzIC-4F blend involves efficient exciton dissociation,higher charge collection and transfer rates,better crystallinity,and optimal phase separation.Therefore,OSCs based on PM6:PzIC-4F as the active layer exhibited a PCE of 16.48% with an open circuit voltage (Voc) and energy loss of 0.880 V and 0.53 eV,respectively.Accordingly,this work demonstrated a promising approach by designing phenazine-based NFAs for achieving high-performance OSCs.

Since the evolving standardization of cellular V2X (C-V2X) technologies is continuously developed by 3GPP,research on new radio (NR-V2X) has been on schedule by academic and industries.Though millimeter wave (mmWave) frequency band is supposed to provide large transmission bandwidth,yet the development of mmWave band in NR-V2X is still in preliminary stage.In this article,a comprehensive discussion of mmWave NR-V2X is given covering trends,standardization landscape,and enabling technologies,aiming at tackling the challenge of channel modeling,directional channel access,beamforming and blockage management.The vision of mmWave NR-V2X is to fully support the development of automated driving,holographic control display and improved in-car infotainment for the future.
Ultrafast investigation of room temperature valley polarization in "optical bilayer" WS_2

Monolayer transition metal dichalcogenides(TMDCs)have become a promising platform in valleytronics due to possessing the regulatable valley degrees of freedom. While, as a result of the rapid intervalley scattering, it is difficult to measure the PL valley polarization of monolayer TMDCs at room temperature, which limits their application in valleytronics devices. Here, we report a room temperature photoluminescence(PL)valley polarization up to 3.73% in an "optical bilayer" WS_2 formed by transferring monolayer WS_2 onto flat Ag film. Furthermore, in the transient absorption(TA)measurements, a remarkably long valley depolarization lifetime is found. Thus, we demonstrate the valley properties of such "optical bilayer" WS_2 resemble actual bilayer WS_2, in which the robust valley polarization can be attributed to the phonons depletion effect and the blocked interlayer hopping processes. These peculiar valley features in "optical bilayer" WS_2 provide a particularly simple method to enhance valley control at room temperature.
Heralded entanglement between error-protected logical qubits for fault-tolerant distributed quantum computing

Quantum error correction is essential for achieving reliable quantum information processing tasks, as it can mitigate the detrimental effects of noise by encoding single-qubit information into a larger quantum system. However, the generation of distributed entanglement between logical qubits located within two spatially separated nodes presents a significant resource-intensive challenge that has yet to be overcome. Here we present a heralded protocol for generating distributed entanglement between two nonlocal error-protected logical qubits. A high-dimensional single photon can evolve physical qubits into a logical qubit that entangles with the photon and then converts logical qubit-photon entanglement into entanglement between two logical qubits, when the photon state is properly tuned and an effective photon-spin interface between single photons and individual spins is exploited. Furthermore, the success of the entanglement generation is heralded by the detection of the photon, and the corresponding efficiency can, in principle, approach unity. These distinguished features make our protocol highly appealing for future large-scale quantum technologies.
Evolution of artificial ion channels

Protein ion channels on a cell membrane generate action potentials for cellular signal transduction,and regulate biological activities during life.Since the discovery of the asymmetric ion transport phenomenon in quartz nanopipettes by Bard and colleagues,synthetic nanofluidic materials and devices have attracted a lot of research interests from the scientific community,with efforts having been made to mimic the ionic gating and electrogenic functions of biological ion channels.Over the past two decades,this interdisciplinary field of physics,chemistry and materials science has developed artificial ion channels (AICs).
The seesaw action:balancing plant immunity and growth

Plants face the constant challenge of allocating limited resources to both immunity and growth to ensure survival and reproduction,therefore,one major aim of crop breeding is to balance disease resistance with yield.This review highlights the intricate interplay between plant immunity and growth,shedding light on the underlying molecular mechanisms and potential strategies for optimizing these vital agronomic traits.We discuss the role of signaling pathways,epigenetic regulation,long non-coding RNAs,and post-translational modifications in mediating the balance between immunity and growth.We also highlight recent findings on the rewiring of signals of immunity and growth which provide valuable insights into manipulation of these pathways for crop improvement.By understanding the fine-tuning mechanisms of plant immunity and growth,we can develop innovative approaches to enhance disease resistance in future crops without compromising yield potential.
Growth of ablative Rayleigh-Taylor instability induced by time-varying heat-flux perturbation

The evolution of ablative Rayleigh-Taylor instability (ARTI) induced by single-mode stationary and time-varying perturbations in heat flux is studied numerically in two dimensions.Compared with the stationary case,time-varying heat-flux perturbation mitigates ARTI growth because of the enhanced thermal smoothing induced by the wave-like traveling heat flux.A resonance is found to form when the phase velocity of the heat-flux perturbation matches the average sound speed in the ablation region.In the resonant regime,the coherent density and temperature fluctuations enhance the electron thermal conduction in the ablation region and lead to larger ablation pressure and effective acceleration,which consequently yield higher linear growth rate and saturated bubble velocity.The enhanced effective acceleration offers increased implosion velocity but can also compromise the integrity of inertial confinement fusion shells by causing faster ARTI growth.

Extreme Risk Measurement of Carbon Market Considering Multifractal Characteristics

Influenced by the global economy,politics,energy and other factors,the price of carbon market fluctuates sharply.It is of great practical significance to explore a suitable measurement method of extreme risk of carbon market.Considering that the return series of carbon market has the characteristics of leptokurtosis,fat tail,skewness and multifractal,and there maybe many extreme risk values in the carbon market,this paper introduces the Skewed-t distribution which can describe the characteristics of leptokurtosis,fat tail and skewness of return series into MSM model which can describe multifractal characteristic of return series to model volatility of carbon market.On the basis,based on the extreme value theory,this paper constructs Skewed-t-MSM-EVT model to measure extreme risk of carbon market.This paper chooses EUA market as the object to study extreme risk of carbon market,and draws the following conclusions:Skewed-t-MSM-EVT model has significantly higher prediction accuracy for carbon market's VaR than MSM-EVT models under other distributions (including normal distribution,t distribution,GED distribution);Skewed-t-MSM-EVT model is superior to traditional Skewed-t-FIGARCH-EVT and Skewed-t-GARCH-EVT models in predicting carbon market's VaR.This research has important practical significance for accurately grasping the risk of carbon market and promoting energy conservation and emission reduction.
Giant photoinduced reflectivity modulation of nonlocal resonances in silicon metasurfaces

Metasurfaces offer a unique playground to tailor the electromagnetic field at subwavelength scale to control polarization,wavefront,and nonlinear processes.Tunability of the optical response of these structures is challenging due to the nanoscale size of their constitutive elements.A long-sought solution to achieve tunability at the nanoscale is all-optical modulation by exploiting the ultrafast nonlinear response of materials.However,the nonlinear response of materials is inherently very weak,and,therefore,requires optical excitations with large values of fluence.We show that by properly tuning the equilibrium optical response of a nonlocal metasurface,it is possible to achieve sizable variation of the photoinduced out-ofequilibrium optical response on the picosecond timescale employing fluences smaller than 250 μJ∕cm~2,which is 1 order of magnitude lower than previous studies with comparable reflectivity variations in silicon platforms.Our results pave the way to fast devices with large modulation amplitude.
Enhanced mechanical property by introducing bimodal grains structures in Cu-Ta alloys fabricated by mechanical alloying

Dispersion-strengthened copper alloys can achieve ultra-high strength, but usually at the expense of ductility. In this study, a strategy for overcoming strength-ductility tradeoff of Cu alloys is realized through the introduction of bimodal grains structures. Cu-Ta alloys with only 0.5 at.% Ta content were successfully prepared by mechanical alloying combined with spark plasm sintering. The samples prepared by one-step and two-step ball milling methods are named as Cu-Ta ( Ⅰ) and Cu-Ta ( Ⅱ), respectively. The microstructural characterizations revealed that ultra-fine equiaxed grains with uniformly dispersed Ta precipitates were obtained in the Cu-Ta alloys. High strength of 377 MPa for yield strength together with elongation of ~8% was obtained in Cu-Ta ( Ⅰ). Bimodal grains structures composed of fine-grain zones and coarse-grain zones were successfully introduced into Cu-Ta ( Ⅱ) by a two-step ball milling approach, and both yield strength (463 MPa) and elongation ( ~15%) were significantly synergistic enhanced. The hardness values of both Cu-Ta ( Ⅰ) and Cu-Ta ( Ⅱ) were almost kept nearly constant with the increase of annealing time, and the softening temperatures of Cu-Ta ( Ⅰ) and Cu-Ta ( Ⅱ) are 1018 and 1013 °C, reaching 93.9% and 93.5% T_m of pure Cu (1083 °C), respectively. It reveals that the Cu-0.5 at.% Ta alloys exhibit excellent thermal stability and exceptional softening resistance. Ta nanoclusters with semi-coherent structures play an essential role in enhancing the strength and microstructural stability of alloys. Bimodal structures are beneficial to the activation of back stress strengthening and the initiation and propagation of microcracks, thus obtaining the extraordinary combination of strength and elongation. This study provides a new way to fabricate dispersion-strengthened Cu alloys with high strength, high elongation, excellent thermal stability and softening resistance, which have potential application value in the field of the future fusion reactor.
Comprehensive Analysis of the Role of Forkhead Box J3 (FOXJ3) in Human Cancers

Forkhead box J3 (FOXJ3) is a member of the forkhead box (Fox) family. Recently, increasing evidence has revealed the relationship between Fox family members and cancer. FOXJ3 is involved in various types of cancer, including lung cancer, tongue squamous carcinoma, and prostate cancer; however, a comprehensive pan-cancer analysis of FOXJ3 remains lacking. Here, we explored the function of FOXJ3 across cancers using online websites and databases including TIMER2.0, SangerBox, UALCAN, GEPIA2.0, cBioPortal, Cancer- SEA,STRING, BioGRID and Metascape to analyze the role of FOXJ3 in cancers. Abnormal expression of FOXJ3 was found in various tumors. The genetic alteration percentage in tumors was determined, and elevated FOXJ3 expression was found to be associated with worse overall survival in brain lower grade glioma(LGG), liver hepatocellular carcinoma (LIHC), sarcoma (SARC) and thyroid carcinoma. Elevated FOXJ3 expression was related to worse prognosis with disease-free survival in adrenocortical carcinoma, LGG and LIHC. FOXJ3 expression was related to immune infiltration in several cancers. Enrichment analysis showed that histone modification, the TGF-β signaling pathway, and chromatin organization were the top three enriched ontology clusters of the top 100 similar genes of FOXJ3. Our pancancer analysis provides comprehensive insights into FOXJ3 from the perspective of bioinformatics in different cancers, where it serves as a potential biomarker for prognosis, especially in LGG and LIHC. FOXJ3 is also correlated with immune infiltrates in certain human tumors.
