The future optoelectronic technologies may operate on the basis of individual elementary particles, including photons and electrons. Achieving control knobs at such a fundamental level necessitates substantial progress in the domains of materials and device engineering. Recently, two-dimensional (2D) materials have become an important platform for such investigations, as their layered crystal structures give rise to inherent in-plane confinement of electrons. Defect engineering and/or van der Waals heterostructure device fabrication provide multiple strategies to induce further lateral confinement, leading to discrete electronic states required for both single photon emission and single electron operation. Herewith, we review the cutting-edge developments regarding single photon sources and single electron transistors in 2D materials. We provide a perspective on the convergence of these two separate fields into single electron-photon device platforms enabled by the unique characteristics of 2D systems.

Bacterial infections challenge clinical medicine, and “electrostimulation” and “catalytic therapy” offer novel antibacterial strategies beyond antibiotics and metal ions. Herein, a bimetallic galvanic cell metasurface composed of biosafe zirconium (Zr), titanium (Ti), and tantalum (Ta) is fabricated on polymer implants using a developed plasma modification system (PIII&PHS). The galvanic cell metasurface harbors an asymmetric charge to modulate electron transfer, and enables “electron beam flow” to surpass the reactivity limits of metals. Remarkably, the galvanic cell metasurface adeptly modulates electron transfer to reduce the energy supply and triggers the bacterial reactive oxygen species (ROS) imbalance to cause death. The antibacterial mechanism is validated, and the universality is demonstrated. Rat osteomyelitis, cranial defect, and rabbit femoral defect models corroborate the excellent osteointegration ability of the galvanic cell metasurface. The results reveal that incorporating biosafe bimetallic asymmetric charges into a metasurface is a novel and effective strategy for designing antibacterial medical materials.

Lithium-sulfur batteries as a promising candidate for the next generation of battery systems face major challenges in their commercialization process, primarily due to the irreversible loss of active sulfur substances during the operation of the battery and the instability of the lithium anode. As a critical component of lithium-sulfur batteries, the separator not only separates the cathodes and anodes to prevent battery short circuits but also provides a pathway for ion transport. Constructing functionalized high-performance separators can effectively suppress the 'shuttle effect' and stabilize the lithium anodes, thereby enhancing the performance of lithium-sulfur batteries and accelerating their practical application process. In recent years, research on separators for lithium-sulfur batteries has been increasing. However, existing reviews on lithium-sulfur battery separators seem to be inadequate, making it difficult to provide effective guidance for researchers. To address this, this review comprehensively elaborates on the research work of functionalized separators from three perspectives: modified separators, electrospun separators, and polymer electrolyte separators. In addition, we have conducted a preliminary evaluation of the staged applications of these three types of separators. This review not only provides directions for subsequent scientific research work but also offers effective guidance for enterprises in the production of functionalized high-performance separators.

Nanocellulose/MXene composites, renowned for their exceptional conductivity, mechanical strength and multifunctionality, have garnered significant attention as promising materials for next-generation technologies. Biomass-derived nanocellulose offers mechanical strength, high aspect ratio and biocompatibility, while two-dimensional MXene exhibits high electrical conductivity, surface area and hydrophilicity. Hydrogen bonding interactions are developed between the hydrophilic groups on nanocellulose (-OH) and MXene (-OH, -F, =O), enhancing the mechanical and electrical properties of nanocellulose/MXene composites. The combined mechanical robustness and conductivity highlights their vast potential in advanced smart electronics, energy storage and biomedicine. Previous reviews have focused on individual optimization strategies or specific applications of nanocellulose/MXene composites. Conversely, this review emphasizes the interrelationship between manufacturing techniques, structural properties, and multifunctional applications of nanocellulose/MXene composites, aiming to facilitate rational design and performance optimization in future research. The fabrication and fundamental properties of nanocellulose and MXene are first summarized. Then, the production technologies and emerging applications of nanocellulose/MXene composites (fibers, films and gels) in electromagnetic interference shielding, supercapacitors, sensors, water treatment and thermal management are summarized. Notably, the exploration of life cycle assessment to nanocellulose/MXene composites enables the comprehensive environmental evaluation and process optimization, providing sustainable policies and market promotion. Finally, we present the current research challenges and future directions, including improving production efficiency, optimizing modification strategies and developing scalable manufacturing processes for nanocellulose/MXene composites.

Mechanoreceptors, such as Merkel discs in the somatosensory system, play a crucial role in converting mechanical stimuli into electrical signals, enabling spatial discrimination and perception. This study investigates a conventional van der Waals heterostructures field-effect transistor (VHFET) with strategically positioned access regions (AR) to mimic unique neuronal behaviors. The neuronal VHFET with AR (VHFET-AR) device, constructed using 2D materials including molybdenum disulfide as the channel, hexagonal boron nitride as the tunneling insulator, and graphene as the floating gate, functions as a synaptic device designed to replicate the role of Merkel discs in human skin. The VHFET-AR device successfully reproduces fundamental nervous system functions, including spike amplitude-dependent plasticity, spike duration-dependent plasticity, spike number-dependent plasticity, and slow adaptation (SA). It further demonstrates long-term potentiation and depression modulated by spike intervals, exhibiting synaptic plasticity similar to that of biological systems. Unlike complex and bulky electronic circuits, the VHFET-AR device can perform inverse notch signaling and lateral inhibition at a frequency of approximately 11.23 Hz, closely aligning with the low-frequency stimuli (5–15 Hz) characteristic of biological Merkel discs, which are essential for spatial localization and discrimination. The compact design of the VHFET-AR device highlights its merit in minimizing the size of the electronic circuit. By incorporating properties such as inverse notch signaling, lateral inhibition, and SA, the VHFET-AR device represents a significant advancement in developing artificial mechanoreceptor hardware, offering a closer emulation of the complex mechanisms underlying the biological somatosensory system.

Oligomeric acceptors are increasingly recognized as promising n-type materials for organic photovoltaics (OPVs) due to their precise molecular structures, long-term stability, and high efficiency. However, inferior molecular packing and high energy losses have hindered their further use. Here, we overcome these challenges by developing an asymmetric small molecular acceptor (SMA), BTP-J17, and applying it as the second acceptor component in OPVs composed of PM6:DIBP3F-Se:BTP-J17 (refer to our recent work on dimeric acceptor DIBP3F-Se). The BTP-J17 is very miscible with the DIBP3F-Se and appears to diffuse into the host donor-acceptor interface. The ensuing ternary cells exhibit enhanced exciton dissociation, improved carrier mobility, and more efficient charge extraction. Optimised OPVs based on PM6:DIBP3F-Se:BTP-J17 show enhanced open-circuit voltage (VOC) while maintaining the high short-circuit current (JSC) from the binary blends, boosting the power conversion efficiency (PCE) from 18.40 % to 19.60 %. By integrating MgF2 as an antireflection coating and n-doping the ternary BHJ with ethyl viologen (EV), we were able to further boost the PCE to 20.5 % (uncertified) and simultaneously extended the outdoor stability to seven weeks. Our findings highlight the crucial role of asymmetric SMA as an additional component for boosting the performance and stability of OPVs.

High-entropy battery materials (HEBMs) have emerged as a promising frontier in energy storage and conversion, garnering significant global research interest. These materials are characterized by their unique structural properties, compositional complexity, entropy-driven stabilization, superionic conductivity, and low activation energy. The early 2020 s have seen remarkable advancements in solid-state chemistry and physics, propelled by high-throughput computation and experimentation, which have sparked a revolution in the development of HEBMs. Despite these advances, a systematic understanding of the underlying principles and processes governing HEBMs remains limited. This review provides a comprehensive analysis of the design, synthesis, structural evolution, and entropy stabilization of emerging HEBMs, with a particular emphasis on secondary rechargeable batteries and the design parameters spanning from low to high entropy in both liquid and solid-state technologies. Furthermore, the review explores the impact of multi-component complexity on oxygen evolution, electro-chemo-mechanical behavior, zero-strain performance, and the development of Co/Mn-free anodes and cathodes. We highlight recent breakthroughs in the synthesis of high-entropy solid electrolytes (HESEs) and high-entropy liquid electrolytes (HELEs), including ultrafast synthesis techniques and entropy-driven strategies that enhance ion transport and stability under extreme conditions.

These materials are characterized by their unique structural properties, compositional complexity, entropy-driven stabilization, superionic conductivity, and low activation energy. The early 2020 s have seen remarkable advancements in solid-state chemistry and physics, propelled by high-throughput computation and experimentation, which have sparked a revolution in the development of HEBMs. Despite these advances, a systematic understanding of the underlying principles and processes governing HEBMs remains limited. This review provides a comprehensive analysis of the design, synthesis, structural evolution, and entropy stabilization of emerging HEBMs, with a particular emphasis on secondary rechargeable batteries and the design parameters spanning from low to high entropy in both liquid and solid-state technologies. Furthermore, the review explores the impact of multi-component complexity on oxygen evolution, electro-chemo-mechanical behavior, zero-strain performance, and the development of Co/Mn-free anodes and cathodes. We highlight recent breakthroughs in the synthesis of high-entropy solid electrolytes (HESEs) and high-entropy liquid electrolytes (HELEs), including ultrafast synthesis techniques and entropy-driven strategies that enhance ion transport and stability under extreme conditions.

A pair of A1-A2-type polymer acceptors (PY-DTBT and PY-DT-BT) including acceptor backbones (A1) with fused- or unfused-electron-deficient linkers dithieno-benzothiadiazole (DTBT) or DT-BT (A2), and corresponding comparative polymer acceptor PY-IT are synthesized for all-PSCs, respectively. PY-DTBT and PY-DT-BT neat film exhibit slightly blue-shifted absorption but higher absorption coefficients, and slightly down-shifted energy levels compared to PY-IT. Moreover, PY-DTBT exhibits a more rigid backbone with tighter interchain packing compared to PY-IT and PY-DT-BT, thus achieving better electron-transport in neat films. The PM6/PY-DTBT films possess well-distributed fibril network morphology with suitable phase segregation and better face-on crystallization, which can promote charge generation and extraction, and better-balanced charge mobilities in corresponding all-PSCs. Consequently, the PM6/PY-DTBT LBL-processed all-PSCs produce a top-ranked PCE of 17.58 % with a small energy loss (Eloss) of 0.51 eV, which is obviously higher than that of PM6/PY-IT (16.84 %) and PM6/PY-DT-BT (13.24 %). Furthermore, the all-PSCs based on PM6/(PY-DTBT90 %:PY-IT10 %) achieved a champion PCE of 18.5 % with remarkable FF, which is the one of highest reported value for the electron-deficient linker-based PSMAs in all-PSCs. This work demonstrates that employing DTBT as electron-deficient fused-ring linkage paves the way to achieve excellent polymer acceptors for further improving the efficiency of all-PSCs with small Eloss simultaneously.
