The explosive growth of computational data poses significant challenges to conventional von Neumann architectures and network processing capabilities. Two-dimensional floating gate memristors, with their compact footprint, high storage density, prolonged data retention, and rapid programming speeds, are emerging as ideal candidates for neuromorphic computing systems that integrate memory and computation. However, achieving full hardware implementation of deep neural networks necessitates the emulation of nonlinear activation functions. Here, we present a reconfigurable floating gate memristor (FGM) based on a MoS2/hBN/graphene heterostructure. The device demonstrates exceptional performance, including no significant changes in conductive states over a 3600 s test period and 66 linearly tunable conductance states, alongside multilevel conductance tunability under optical pulses. Distinct from traditional research focused solely on synaptic weight updates, we demonstrate an innovative reconfigurable “dual-function hardware unit.” By strictly controlling back gate voltages below the threshold voltage (Vth), we successfully emulate both rectified linear unit (ReLU) and leaky rectified linear unit (Leaky ReLU) behaviors in floating gate and half-floating gate devices, respectively. Integrated into LeNet and AlexNet architectures, the FGM-enabled systems achieve markedly higher inference accuracy compared to activation-free models in classification tasks on the FashionMNIST and 43-class traffic sign data sets. This device simultaneously functions as a tunable synaptic weight and a native nonlinear activation function, thereby opening up the possibility of fully hardware-implemented neuromorphic systems.

Hybrid two-dimensional (2D) materials have attracted increasing interest as platforms for tailoring electronic properties through interfacial design. Very recently, a hybrid 2D material termed glaphene, which combines monolayers of 2D silica glass and graphene, was experimentally realized. Inspired by glaphenes, we proposed a class of similar structures named glaphynes, which are formed by stacking SiO2 monolayers onto α-, β-, and γ-graphynes. Graphynes are 2D carbon allotropes with the presence of acetylenic groups (triple bonds). The glaphynes’ structural and electronic properties were investigated using the self-consistent-charge density functional tight-binding (SCC-DFTB) method, as implemented in the DFTB+ package. Our analysis confirms their energetic and structural stability. We have observed that in the case of glaphynes, the electronic proximity effect can indeed open the electronic band gap, but not for all cases, even with the formation of Si–O–C bonds between silica and graphynes.

Regulating solar heat gain is crucial for reducing heating, ventilation, and air conditioning (HVAC) energy consumption in buildings and promoting sustainable responses to climate change. Current thermochromic materials suffer from poor durability and limited optical modulation. Here, the study presents a durable thermochromic coating based on an organogel-higher alkane (HA) composite. The reversible phase change of HA within the organogel induces light reflection, scattering, and diffraction, while carbon black particles enhance the absorptance modulation, achieving a maximum change of 0.35. For practical application on cement, where a highly reflective layer is applied beneath, the absorptance modulation can reach 0.25, exceeding reported values for other thermochromic systems that could be applied to the roof or wall. The material withstands prolonged UV exposure and repeated thermal cycling without degradation, making it suitable for real-world applications. Simulations incorporating a reflective underlayer demonstrate potential annual HVAC energy savings of up to 3% across diverse climate zones. This work introduces a robust, scalable, and season-adaptive thermochromic coating for sustainable building energy management.

Doxorubicin (DOX)-induced cardiomyopathy remains therapeutically challenging due to the absence of pathway-specific interventions. Ferroptosis of cardiac microvascular endothelial cells (CMECs) is a major driver of disease progression, yet precise therapeutic strategies remain limited. Here, mechanistic analyses identified lncRNA TUG1 as an upstream promoter of CMEC ferroptosis through the miR-153-5p/MMP2-TIMP2/TFR-1 axis. Guided by this mechanism, a translational construct was developed by cloaking mesoporous silica nanoparticles carrying TUG1-targeting siRNA with neutrophil membranes (NM@si-TUG1/MSN). The neutrophil membrane coating enabled robust cardiac tropism and preferential CMEC uptake. In a murine model of DOX-induced cardiomyopathy, NM@si-TUG1/MSN accumulated in the heart, achieved effective TUG1 knockdown, and markedly reduced ferroptosis. Relative to free siRNA and uncoated nanoparticles, the nanocomplex produced superior outcomes, including restoration of microvascular integrity, reduced fibrosis, and significant improvement in cardiac function. This study characterizes a regulatory axis in DOX-induced cardiomyopathy and demonstrates a targeted biomimetic nanotherapy that interrupts microvascular ferroptosis and limits disease progression. The data support the feasibility of this approach for clinical translation.

A significant amount of ferrous scrap resources remain unrecycled, and the abundant iron content gives them potential as environmental catalysts. However, the practical application of ferrous scrap in catalysis remains a significant challenge. Herein, a strategy based on rapid solidification to increase the specific surface area, regulate the microstructure, and introduce high residual stress in ferrous scrap is proposed, leading to enhanced catalytic performance. The introduction of high residual stress and the construction of an amorphous structure significantly enhance performance, enabling a degradation efficiency of 98% within 40 s and a high kobs of 5.866 min−1. Theoretical calculations reveal that progressively optimizing the phase structure—from the α-phase to the ε-phase and then an amorphous phase—promotes persulfate (PS) adsorption, and significantly enhances the electron transfer capability. Furthermore, optimizing the composition of the catalyst improves its stability to 30 cycles and develops a novel catalyst with dual functionality for both pollutant degradation and water electrolysis, exhibiting an oxygen evolution reaction (OER) overpotential η10 of 309 mV. These findings provide a new perspective for the recycling of ferrous scrap and offer innovative ideas for developing multifunctional catalytic materials, which are capable of addressing integrated challenges in water treatment and clean energy conversion.

Sodium-ion batteries (SIBs) have attracted considerable attention for large-scale energy storage owing to their low cost, high safety, and resource abundance. Among various anode materials, hard carbon stands out for its high capacity and low operating voltage. However, its practical application is severely limited by interfacial instability, manifested in low initial coulombic efficiency (ICE) and poor cycling stability. Recognizing interfacial instability as the key bottleneck for the commercialization of hard carbon anodes, this review constructs a three-pillar framework that comprises structural modulation, surface coating, and presodiation, and proposes a synergistic design paradigm to systematically tackle these challenges. It reveals the mechanisms by which interface engineering suppresses side reactions, guides the formation of the solid electrolyte interphase (SEI) film, and compensates for initial sodium loss. This review also provides an in-depth analysis of interfacial failure processes and the structure–function relationships in SEI film regulation, and highlights SEI film characterization techniques as essential tools for understanding interfacial reaction mechanisms and validating the effectiveness of interface engineering strategies. Building on these insights, the review distills core interface design principles for achieving high-ICE and long-life hard carbon anodes, and offers a clear roadmap for the rational design of high-performance hard carbon electrodes and the commercialization of SIBs.

Flowless Zn–bromine batteries (FL–ZBBs) are attracting attention as a route to overcome the inherent system-level limitations of conventional flow batteries. However, the difficulty of achieving high ZnBr2 utilization and ultra-high areal capacity jeopardize practical feasibility: Under practically relevant conditions, Zn-hosting electrodes suffer from top-plating issues and dendrite-triggered “dead” Zn accumulation, which deteriorates reversible Zn plating/stripping. This work presents a stepwise activation (SWA) electrode that guides top-plating-free, bottom-to-top sequential Zn deposition. The SWA architecture is designed by introducing insulating porous membranes physically separating stacked CF layers while electrically linking through controlled partial Zn penetration. Benefiting from SWA-guided Zn deposition, FL-ZBBs can stably retain higher Coulombic and energy efficiencies even at a high current cycling (20 mA cm−2) over 10 000 cycles. For the first time, we demonstrate a stable ultra-high capacity cycling (100 mAh cm−2) of FL-ZBB with SWA electrode by maximizing the ZnBr2 utilization (∼33%). This simple, scalable SWA design offers broad applicability, enabling high-capacity operation in flowless batteries and extending to other metal-deposition-limited redox systems.
无液流锌溴电池（FL-ZBBs）作为一种克服传统液流电池固有的系统级局限性的途径而备受关注。然而，实现高ZnBr2利用率和超高面容量的难度危及了实际可行性：在实际相关条件下，含锌电极存在镀顶问题和枝晶引发的“死”锌积累，从而恶化了锌的可逆镀/剥离。这项工作提出了一种逐步激活（SWA）电极，用于指导无顶镀，自下而上的顺序Zn沉积。SWA架构是通过引入绝缘多孔膜来物理分离堆叠的CF层，同时通过控制部分Zn渗透进行电连接。受益于swa引导的Zn沉积，FL-ZBBs即使在高电流循环（20 mA cm−2）超过10,000次循环下也能稳定地保持较高的库仑和能量效率。我们首次通过最大限度地提高ZnBr2的利用率（约33%），证明了使用SWA电极的FL-ZBB具有稳定的超高容量循环（100 mAh cm−2）。这种简单、可扩展的SWA设计具有广泛的适用性，可在无液电池中实现高容量操作，并扩展到其他金属沉积受限的氧化还原系统。
