AbstractHybrid tin‐lead (Sn‐Pb) perovskites have garnered increasing attention due to their crucial role in all‐perovskite tandem cells for surpassing the efficiency limit of single‐junction solar cells. However, the easy oxidation of Sn2+ and fast crystallization of Sn‐based perovskite present significant challenges for achieving high‐quality hybrid Sn‐Pb perovskite films, thereby limiting the device's performance and stability. Herein, an all‐in‐one additive, 2‐amino‐3‐mercaptopropanoic acid hydrochloride (AMPH) is proposed, which can function as a reducing agent to suppress the formation of Sn4+ throughout the film preparation. Furthermore, the strong binding between AMPH and Sn‐based precursor significantly slows down the crystallization process, resulting in a high‐quality film with enhanced crystallinity. The remaining AMPH and its oxidation products within the film contribute to improves oxidation resistance and a substantial reduction in defect density, specifically Sn vacancies. Benefiting from the multifunctionalities of AMPH, a power conversion efficiency (PCE) of 23.07% is achieved for single‐junction narrow‐bandgap perovskite solar cells. The best‐performing monolithic all‐perovskite tandem cell also exhibits a PCE of 28.73% (certified 27.83%), which is among the highest efficiency reported yet. The tandem devices can also retain over 85% of their initial efficiencies after 500 hours of continuous operation at the maximum power point under one‐sun illumination.

Published: November 2024

AbstractOrganic nonvolatile memory has been considered a low‐cost memory technology for flexible electronics and Internet‐of‐things (IoT). However, a major concern is the nonuniformity of memory units, which is primarily caused by random grain boundaries, interface defects, and charge traps, making it difficult to develop high‐density reliable memory arrays. This nonuniformity problem would induce read error, which is directly caused by the narrow distribution margin of memory states and low noise tolerance in conventional organic memory cells. To break this limitation, a novel 2T memory cell employing a NOT‐gate‐like architecture achieving self‐enhancing noise tolerance is presented. This unique cell consists of a pair of commonly‐gated memory transistors with contradictory “write‐and‐erase” features. It functions as a voltage divider, producing a well‐distinguished binary voltage output capability. The concept and design model of this brand‐new 2T memory cell is thoroughly discussed. It is originally characterized by noise‐tolerant memory cells irrespective of device nonuniformity. The noise tolerance range of this 2T memory cell is also investigated. The binary voltage‐readable memory state with a large noise tolerance range is obtained. Moreover, the conceptual design of the 1T2T FeRAM cell is further developed for low‐cost voltage‐readable memory technology in wearable electronic applications.

Published: November 2024

AbstractMacrosuperlubric materials are pivotal for reducing friction and wear in engineering applications. However, current solid superlubricants require intricate fabrication and specific conditions (e.g., vacuum or inert atmospheres), while liquid superlubricants are prone to creep, leakage, and corrosion. Here, a novel semisolid subnanometer nanowire (SNW) superlubrication material based on the shear‐thinning effect is introduced to overcome these challenges. The SNWs achieve an exceptionally low friction coefficient (0.008–0.009) with silicon nitride (Si3N4) and polytetrafluoroethylene (PTFE) tribo‐pairs, demonstrating a brief running‐in period (≈39 s) and stable superlubrication over extended friction (12 h, >120 000 cycles). The combination of the shear‐thinning network structure mechanism, the adsorption membrane mechanism, and hydrodynamic effects provides a synergistic effect, playing a crucial role in achieving superlubricity. Additionally, SNWs can be combined with various base oils to create semisolid gel lubricants with superlubricating properties. This innovative approach addresses the limitations of current superlubrication systems and introduces a new category of semisolid gel lubricants, significantly expanding the applications of superlubrication materials.

Published: November 2024

AbstractOriented zinc (Zn) electrodeposition is critical for the long‐term performance of aqueous Zn metal batteries. However, the intricate interfacial reactions between the Zn anode and electrolytes hinder a comprehensive understanding of Zn metal deposition. Here, the reaction pathways of Zn deposition and report the preferential formation of Zn single‐crystalline nuclei followed by dense Zn(002) deposition is elucidated, which is induced by a gradient solid‐electrolyte interphase (SEI). The gradient SEI composed of abundant B‐O and C species facilitates faster Zn2+ nucleation rate and smaller nucleus size, promoting the formation of Zn single‐crystalline nuclei. Additionally, the homogeneity and mechanical stability of SEI ensure the crystallographic reorientation of Zn anodes from Zn(101) to (002) planes, efficiently inhibiting dendrite growth and metal corrosion during the Zn2+ stripping/plating process. These advantages significantly enhance the stability of the Zn anode, as demonstrated by the prolonged cycling lifespan of symmetric Zn batteries and exceptional reversibility (>99.5%) over 5000 cycles in Zn//Cu asymmetric batteries. Notably, this strategy also enables the stable operation of anode‐free Zn//I2 batteries with a long lifespan of 3000 cycles. This work advances the understanding of Zn electrochemical behaviors, encompassing Zn nucleation, growth, and Zn2+ stripping/plating.

AbstractInterfacial solar evaporation‐based seawater desalination is regarded as one of the most promising strategies to alleviate freshwater scarcity. However, the solar evaporation rate of real seawater is significantly constricted by the ubiquitous salts present in seawater. In addition to the common issue of salt accumulation on the evaporation surface during solar evaporation, strong hydration between salt ions and water molecules leads to a lower evaporation rate for real seawater compared to pure water. Here a facile and general strategy is developed to reverse this occurrence, that is, making real seawater evaporation faster than pure water. By simply introducing specific mineral materials into the floating photothermal evaporator, ion exchange at air–water interfaces directly results in a decrease in seawater evaporation enthalpy, and consequently achieves much higher seawater evaporation rates compared to pure water. This process is spontaneously realized during seawater solar evaporation. Considering the current enormous clean water production from evaporation‐based desalination plants, such an evaporation performance improvement can remarkably increase annual clean water production, benefiting millions of people worldwide.

Published: November 2024

AbstractRadiofrequency ablation (RFA), a critical therapy for hepatocellular carcinoma (HCC), carries a significant risk of recurrence and metastasis, particularly owing to mechanisms involving immune evasion and antigen downregulation via epigenetic modifications. This study introduces a “nano‐epidrug” named MFMP. MFMP, which is composed of hollow mesoporous manganese dioxide (MnO2) nanoparticles, FIDAS‐5 as an MAT2A inhibitor, macrophage membrane, and anti‐PD‐L1 (aPD‐L1), targets HCC cells. By selectively binding to these cells, MFMP initially reverses immune suppression via PD‐L1 inhibition. After endocytosis, MFMP disassembles in the tumor microenvironment, releasing FIDAS‐5 and Mn2+. FIDAS‐5 prevents cGAS methylation, whereas Mn2+ aids STING pathway restoration. In addition, FIDAS‐5 reduces m6A RNA modification, suppressing EGFR expression. These changes enhance HCC antigenicity to promote cytotoxic T cell recognition and cytotoxic killing. Furthermore, MFMP mediates immunogenic cell death in HCC by synergizing with RFA through cGAS DNA demethylation, EGFR mRNA demethylation, and TBK1 protein phosphorylation, thereby inhibiting recurrence and metastasis and enhancing immune memory. Thus, MFMP is a potential adjunctive therapy requiring clinical validation.

AbstractThe research utilized a strategy of chemical unit co‐substitution, successfully developing a novel blue‐green to green excited, deep red‐emitting phosphor, Ca1‐zSrzLi1‐xMg2xAl3‐xN4:yEu2+ (CLA‐2xM‐zS:yEu, 0≤x≤0.8, 0.003≤y≤0.01, 0≤z≤1), through the replacement of [Li−Al]4+ by [Mg−Mg]4+. This phosphor uniquely converts unusable green light to growth‐enhancing deep red, optimizing it for outdoor agriculture. Doping with Sr creates traps, causing a redshift in emission peaks, as confirmed by 7Li nuclear magnetic resonance (NMR) spectra, indicating Li presence and lattice changes. Ca0.2Sr0.8Li0.5MgAl2.5N4:0.005Eu2+ (CLAM‐0.8S) phosphor maintained high luminescence intensity under extreme conditions of 85 °C/85% RH, demonstrating excellent photoluminescence performance and chemical stability, compared with conventional SrLi0.5MgAl2.5N4:0.005Eu2+ (SLMA) and SrLiAl3N4:0.005Eu2+(SLA). Experimental results surprised that the unique Ca0.2Sr0.8Li0.8Mg0.4Al2.8N4:0.005Eu2+ (CLA‐0.4M‐0.8S) prepared light‐converting film, which is mainly excited by green light, demonstrated a 20% increase in optical density of Chlorella compared to the PP film and a remarkable 97.5% increase compared to the control group without any film. These findings suggest that this film has significant potential for applications in outdoor agriculture and other fields.

AbstractFormamidinium‐cesium lead triiodide (FA1‐xCsxPbI3) perovskite holds great promise for perovskite solar cells (PSCs) with both high efficiency and stability. However, the defective perovskite surfaces induced by defects and residual tensile strain largely limit the photovoltaic performance of the corresponding devices. Here, the passivation capability of alkylamine‐modified pyridine derivatives for the surface defects of FA1‐xCsxPbI3 perovskite is systematically studied. Among the studied surface passivators, 3‐(2‐aminoethyl)pyridine (3‐PyEA) with the suitable size is demonstrated to be the most effective in reducing surface iodine impurities and defects (VI and I2) through its strong coordination with Npyridine. Additionally, the tail amino group (─NH2) from 3‐PyEA can react with FA+ cations to reduce the surface roughness of perovskite films, and the reaction products can also passivate FA vacancies (VFA), and further strengthen their binding interaction to perovskite surfaces. These merits lead to suppressed nonradiative recombination loss, the release of residual tensile stress for the perovskite films, and a favorable energy‐level alignment at the perovskite/[6,6]‐phenyl‐C61‐butyric acid methyl ester interface. Consequently, the resulting inverted FA1‐xCsxPbI3 PSCs obtain an impressive power conversion efficiency (PCE) of 25.65% (certified 25.45%, certified steady‐state efficiency 25.06%), along with retaining 96.5% of the initial PCE after 1800 h of 1‐sun operation at 55 °C in air.

Published: November 2024

AbstractHere the performance of phase change material (PCM)‐coated paper made from unbleached kraft pulp is introduced. The applied PCM consists of a mixture of ethylene glycol distearate (EGDS), a well‐known PCM wax material, and a fully substituted cellulose stearoyl ester (CSE). Transfer of the PCM material onto/into paper is achieved by spray as well as blade coating of EGDS + CSE mixture. It is shown that the kind of coating method used does not interfere with observed PCM properties. The significantly higher melt viscosity of the EGDS + CSE blends ensures that the EGDS wax is not bleeding out of the paper, which avoids the use of further encapsulation processes. The PCM behavior, as observed by thermal load measurements, and the thermal buffering of the coated paper is a function of the applied mass of the PCM material applied. The thermal retention exhibited a quasi‐isothermal behavior at ≈65 °C with EGDS + CSE coatings. These effects can offset fluctuations in temperature, and the PCM papers can be employed to achieve a more uniform temperature setting. PCM‐modified papers are therefore interesting candidates for paper‐based packaging or for use in paper‐based sensors, where overheating can strongly affect reliability of results.

AbstractThe bicyclo[3.3.1]nonane ring represents an attractive yet challenging synthetic targets in the field of organic synthesis, especially in a stereocontrolled fashion. Over the past two decades, organocatalysis has emerged as an enabling technology for the facile construction of enantioenriched molecules with remarkably increasing complexity and diversity, and a myriad of chiral architectures containing bicyclo[3.3.1]nonane units were elegantly assembled through organocatalytic asymmetric transformations. This review summarizes recent advancements on this topic (mainly from 2010–2023), emphasizing the reaction types such as desymmetrization and cascade reactions of different prochiral starting materials toward various chiral bicyclo[3.3.1]nonanes as well as their aza, oxa and thio derivatives. Meanwhile, the synthetic strategy, reaction mechanism, substrate scope and synthetic applications of these catalytic reactions are also discussed. We hope that this review will motivate further development and application of organocatalytic asymmetric synthesis of bicyclo[3.3.1]nonane frameworks.

AbstractThe regulation of nanostructures and composition can significantly enhance the electrochemical activity and accelerate electrochemical reaction kinetics of electrode material. Herein, metal organic framework(MOF) is used as self‐sacrificing templates to prepare CoNiSe‐P by hydrothermal with following selenylation and phosphorization treatment. Due to the hollow porous structure, rich electrochemical active sites and elements synergistic influence, the obtained CoNiSe‐P electrode shows a high capacity of 838 C g−1, which is much higher than CoNiSe (322 C g−1) and CoNiP (616 C g−1). Furthermore, CoNiSe‐P electrode shows excellent rate characteristic (685 C g−1 at 20 A g−1) and ultrahigh electrochemical stability with capacity retention of 99.6% after 10 000 cycles. More importantly, an asymmetric supercapacitor is assembled with CoNiSe‐P as the positive electrode and nitrogen‐doped porous carbon as the negative electrode delivers an energy density of 42.4 Wh kg−1 at 266.6 W kg−1 and maintains a specific capacitance of 96.8% after 10 000 cycles. Significantly, the asymmetric supercapacitor shows a high energy density up to 21.3 Wh kg−1 at a very high power density of 21.3 kW kg−1, higher than those of previously reported asymmetric supercapacitors.

AbstractIn colorectal cancer (CRC), BRAF inhibitor (BRAFi) monotherapy appears ineffective, while cisplatin treatment is associated with adverse effects, drug resistance, and reduced efficacy. Herein, a combinatorial approach is being explored to increase the likelihood of effectively killing colorectal cancer cells. The combined effect of BRAFi (PLX4720, Vemurafenib, Dabrafenib, Encorafenib) and cisplatin treatment is examined in BRAFV600E‐mutated (RKO, HT29, Colo‐205) and BRAFwt (Caco‐2) cell lines, as well as in mouse xenografts of RKO cells. Following cisplatin‐only treatment, all cell lines show accumulation within subG1 (apoptotic cells) and G2/M phases, as well as phosphorylation of ERK1/2 and H2AX. Following BRAFi‐only treatment, BRAFV600E‐mutated cells show accumulation within G0/G1 phase, reduced distribution in the S and G2/M phases, inhibition of ERK1/2 phosphorylation, and increased phosphorylation of H2AX. Combined BRAFi and cisplatin treatment synergistically decrease RKO cells viability, reduce phosphorylation of ERK1/2, and increase phosphorylation of H2AX. Importantly, in mouse xenografts of RKO cells, combined PLX4720 and cisplatin treatment show superior therapeutic potential than each monotherapy (P < 0.001). Taken together, in in vitro and in vivo preclinical models, BRAFi and cisplatin combined treatment has shown an improved antitumor effect, rendering it a potential anticancer treatment strategy for BRAF‐mutant colon cancer patients.

AbstractUnderstanding intrinsic exchange bias in nominally single‐component ferromagnetic or ferrimagnetic materials is crucial for simplifying related device architectures. However, the mechanisms behind this phenomenon and its tunability remain elusive, which hinders the efforts to achieve unidirectional magnetization for widespread applications. Inspired by the high tunability of ferrimagnetic inverse spinel NiCo2O4, the origin of intrinsic exchange bias in NiCo2O4 (111) films deposited on Al2O3 (0001) substrates are investigated. The comprehensive characterizations, including electron diffraction, X‐ray reflectometry and spectroscopy, and polarized neutron reflectometry, reveal that intrinsic exchange bias in NiCo2O4 (111)/Al2O3 (0001) arises from a reconstructed antiferromagnetic rock‐salt NixCo1‐xO layer at the interface between the film and the substrate due to a significant structural mismatch. Remarkably, by engineering the interfacial structure under optimal growth conditions, it can achieve exchange bias larger than coercivity, leading to unidirectional magnetization. Such giant intrinsic exchange bias can be utilized for realistic device applications. This work establishes a new material platform based on NiCo2O4, an emergent spintronics material, to study tunable interfacial magnetic and spintronic properties.

AbstractThe vast energy stored in the ocean, which receives an average solar power of ≈60 000 TW per year, surpasses human energy consumption by three orders of magnitude. Harnessing even a small fraction of it holds great promise in addressing global energy and water crises. Here, an integrated device that achieves unprecedented power density up to 1.1 W m−2 with excellent stability through a salinity concentration gradient induced by solar evaporation, while simultaneously producing clean water at a rate of 1.25 kg m−2 h−1 under one sun irradiation is presented. The remarkable electricity generation capability stems from the unique interlayer structure of polyaniline‐graphene oxide‐MnO2 (PANI@GO/MnO2) electrodes, enabling the recovery of electrochemical potentials from a wide range of ion salinity concentrations within the device and the additional Donnan potential generated by the anion‐exchange membrane. Furthermore, periodic flipping of the device effectively reactivates the electrodes and suppresses salt accumulation, enabling long‐term operation. Notably, a prototype device of 8 × 25 cm2 exhibits a short‐circuit current of 10 mA and an open‐circuit voltage of 10.2 V, as well as a clean water production rate of 24.8 g per hour. These findings shed light on the reliable technology for power and freshwater supply in marine environments.

AbstractProton exchange membrane water electrolysis (PEMWE) is a promising technology for green hydrogen production, although its widespread development with state‐of‐the‐art loadings is threatened by the scarcity of iridium (Ir). Homogeneous dispersion of Ir in an immiscible electro‐ceramic matrix can enhance catalytic mass activity and structural stability. The study presents IrySn0.9(1−y)Sb0.1(1−y)Ox solid solutions produced by highly scalable flame spray pyrolysis (FSP) process as efficient anode electrocatalysts for PEMWE, containing only 0.2 mg cm−2 of Ir in the catalyst layer (CL). Intense mixing of metal vapor and large thermal gradients in the precursor‐derived high‐temperature flame aids stabilizing sub‐nanoscale entropic mixing within self‐preserved 4–6 nm particles. Detailed investigations confirm that the one‐step prepared solid solution electrocatalysts exhibit up to fourfold higher activity toward the oxygen evolution reaction (OER) compared to Ir black. The anode of a PEMWE utilizing this catalyst exhibits high performance and stability over 2000 h but with tenfold lower Ir loading than the state‐of‐art.
