OBJECTIVE To describe the time course and management of methotrexate (MTX) toxicity in a 14-year-old Hispanic boy with osteosarcoma treated with high-dose MTX. CASE SUMMARY During the sixth cycle of high-dose MTX, severe intoxication was observed with high MTX plasma concentrations, acute renal failure, and hepatitis, followed by mucositis and moderate myelosuppression. Intensification of urine alkalinization and increased leucovorin dosages did not decrease plasma concentrations of MTX or prevent systemic toxicities. Carboxypeptidase G2 and aminophylline were thus administered as a second-intention rescue strategy. Within 2 weeks, a recovery of clinical symptoms and normalization of the biological abnormalities were observed. Limb salvage surgery was performed, which permitted classifying the patient as an MTX high-responder. Thereafter, MTX was successfully resumed, leading to clinical recovery of the patient. Concomitantly, homocysteine plasma levels, a marker of the pharmacodynamic effect of MTX, were measured. During the intoxication, homocysteine plasma levels were significantly increased, parallel to the excessive MTX plasma concentrations observed. DISCUSSION According to the excessive MTX levels measured in this patient, along with the observed clinical (mucositis) and biological (hepatitis, renal injury) adverse effects, we suggest that MTX may be a cause of these complications. Use of the Naranjo probability scale indicated a probable relationship between the complications and MTX. CONCLUSIONS This observation shows that severe complications observed during one cycle of high-dose MTX is not predictive of the tolerability of further courses. Optimal management of such complications, using specific therapeutic intervention, may be considered.

AbstractThe increasing demand for high‐energy storage solutions has brought attention to the limitations of commercial Lithium‐ion batteries (LIBs). While Lithium metal batteries (LMBs) hold promise as an alternative, their practical use is hindered by interface instability in both the lithium anode and Ni‐rich layered cathode during cycling. In this study, a cost‐effective is introduced, bifunctional film‐forming additive: polyethylene glycol diacrylate (PM475). PM475, a long‐chain organic molecule rich in oxygen‐containing functional groups, can create a flexible and stable protective interface on both the lithium metal anode and Ni‐rich Li[NixCoyMn1−x−y]O2 (NCM) cathode. This PM475 enhances the solid electrolyte interface (SEI) components on the lithium anode, effectively suppressing the growth of lithium dendrites. Furthermore, it establishes a uniform interface layer on the Ni‐rich NCM cathode, significantly improving battery cycle life. Consequently, the Li||Li symmetric cell can endure 400 h of cycling at 2 mA cm−2, and the Li||NCM811 full cell exhibits an impressive capacity retention increase from 44.3% to 88.4% after 250 cycles at 1 C under a high cathode load of 20 mg cm−2. This research highlights PM475 as a highly effective additive for enhancing LMB performance, offering a promising avenue for future high‐energy‐density storage systems.

AbstractHigh temperature dielectric polymers are the favored materials for energy storage devices under harsh‐environment, e.g., electronic devices and power systems. It is widely acknowledged that the energy storage capabilities of dielectric polymers are markedly deteriorated at elevated temperature because of the exponential increased leakage current. Herein, all‐organic dielectric polymer alloys with two‐phase continuous hard‐soft structure have been firstly investigated via blending high glass transition temperature (Tg) fluorinated polyimide (FPI) and high bandgap aliphatic polyimide (API). The large energy band difference between FPI and API is conducive to trap energy and greatly inhibits conduction loss. In addition, the hard and soft molecular chains with two‐phase interlocking structures are more closely arranged, bringing torturous pathways for charge carriers and reducing free volume, which enhances the breakdown strength. FPI/API alloy with high Tg (296 °C) and concurrent large bandgap delivers an ultrahigh discharge energy density of 6.6 J cm−3 at 150 °C and 3.02 J cm−3 at 200 °C with 90% discharge efficiency, significantly surpassing those reported dielectrics. Moreover, the FPI/API alloy exhibits remarkable cyclability and dielectric stability up to 10000 charge‐discharge cycles even at elevated temperatures. This work provides an unprecedented opportunity on structure design of dielectric polymers to achieve high‐temperature energy storage capacitors.

AbstractDesigning efficient multifunctional electrocatalysts for water and urea splitting to produce green hydrogen presents a significant yet worthwhile challenge. Herein, the morphology and electronic structure of cobalt metaphosphate (Co2P4O12) by vanadium (V) doping, resulting in improved electrocatalytic activity and stability for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and urea oxidation reaction (UOR) are simultaneously regulated. Theory calculations show that V‐doped Co2P4O12 (V‐Co2P4O12) can boost the kinetics of catalytic reactions by optimizing the d‐band center of Co atoms and the binding strength of intermediates, as well as enhancing the density of states. Moreover, the doping of V into Co2P4O12 crystalline structure benefits the formation of a thicker amorphous layer during the catalytic process, which could enhance its alkaline corrosion resistance and stability. Additionally, the multilevel nanostructures of V‐Co2P4O12 provide rich active sites for catalytic reactions. As a result, a two‐electrode electrolyzer assembled by V‐doped Co2P4O12 delivers low voltages for overall water and urea splitting. The superior performance suggests that the proposed V‐doping strategy is a promising way to regulate electrocatalytic activity for catering to green electrocatalytic applications.

AbstractHydrogen peroxide (H2O2) is a crucial oxidant in advanced oxidation processes. In situ, photosynthesis of it in natural water holds the promise of practical application for water remediation. However, current photosynthesis of H2O2 systems primarily relies on oxygen reduction, leading to limited performance in natural water with low dissolved oxygen or anaerobic conditions found in polluted water. Herein, a novel photocatalyst based on conjugated polymers with alternating electron donor–acceptor structures and electron‐withdrawing side chains on electron donors is introduced. Specifically, carbazole functions as the electron donor, triazine serves as the electron acceptor, and cyano acts as the electron‐withdrawing side chain. Notably, the photocatalyst exhibits a remarkable solar‐to‐chemical conversion of 0.64%, the highest reported in natural water. Furthermore, even in anaerobic conditions, it achieves an impressive H2O2 photosynthetic efficiency of 1365 µmol g−1 h−1, surpassing all the reported photosynthetic systems of H2O2. This remarkable improvement is attributed to the effective relocation of the water oxidation active site from a high‐energy carbazole to a low‐energy acetylene site mediated by the side chains, resulting in enhanced O2 or H2O2 generation from water. This breakthrough offers a new avenue for efficient water remediation using advanced oxidation technologies in oxygen‐limited environments, holding significant implications for environmental restoration.

AbstractAlthough a suitable vertical phase separation (VPS) morphology is essential for improving charge transport efficiency, reducing charge recombination, and ultimately boosting the efficiency of organic solar cells (OSCs), there is a lack of theoretical guidance on how to achieve the ideal morphology. Herein, a relationship between the molecular structure and the VPS morphology of pseudo‐planar heterojunction (PPHJ) OSCs is established by using molecular surface electrostatic potential (ESP) as a bridge. The morphological evolution mechanism is revealed by studying four binary systems with vary electrostatic potential difference (∆ESP) between donors (Ds) and acceptors (As). The findings manifest that as ∆ESP increases, the active layer is more likely to form a well‐mixed phase, while a smaller ∆ESP favors VPS morphology. Interestingly, it is also observed that a larger ∆ESP leads to enhanced miscibility between Ds and As, resulting in higher non‐radiative energy losses (ΔE3). Based on these discoveries, a ternary PPHJ device is meticulously designed with an appropriate ∆ESP to obtain better VPS morphology and lower ΔE3, and an impressive efficiency of 19.09% is achieved. This work demonstrates that by optimizing the ΔESP, not only the formation of VPS morphology can be controlled, but also energy losses can be reduced, paving the way to further boost OSC performance.

AbstractElectrocatalytic nitrate reduction reaction (NO3RR) toward ammonia synthesis is recognized as a sustainable strategy to balance the global nitrogen cycle. However, it still remains a great challenge to achieve highly efficient ammonia production due to the complex proton‐coupled electron transfer process in NO3RR. Here, the controlled synthesis of RuMo alloy nanoflowers (NFs) with unconventional face‐centered cubic (fcc) phase and hexagonal close‐packed/fcc heterophase for highly efficient NO3RR is reported. Significantly, fcc RuMo NFs demonstrate high Faradaic efficiency of 95.2% and a large yield rate of 32.7 mg h−1 mgcat−1 toward ammonia production at 0 and −0.1 V (vs reversible hydrogen electrode), respectively. In situ characterizations and theoretical calculations have unraveled that fcc RuMo NFs possess the highest d‐band center with superior electroactivity, which originates from the strong Ru─Mo interactions and the high intrinsic activity of the unconventional fcc phase. The optimal electronic structures of fcc RuMo NFs supply strong adsorption of key intermediates with suppression of the competitive hydrogen evolution, which further determines the remarkable NO3RR performance. The successful demonstration of high‐performance zinc‐nitrate batteries with fcc RuMo NFs suggests their substantial application potential in electrochemical energy supply systems.

AbstractPhotocatalytic CO2 reduction plays an important role in solar energy storage and carbon balance. GaN as an III‐V semiconductor material has received extensive attention in the field of photocatalysis. In this study, the porous indium‐doped GaN (In/GaN) micro‐rods are synthesized successfully by a facile hydrothermal method and subsequent controlled atmosphere heat treatment. Photocatalytic CO2 reduction performance of In/GaN is higher than that of pure GaN due to the In doping improves the light absorption efficiency. The primary products are CO and CH4. Among the samples, 3%‐In/GaN exhibits the highest catalytic activity as well as stability and reusability. The yield rates of CO and CH4 can be reached 50.2 and 14.6 µmol · g−1 · h−1, respectively. Furthermore, density functional theory (DFT) calculations reveal that the bandgap is narrowed and the adsorption energy of CO2 molecules is improved by In doping. Moreover, the N‐vacancy detected by electron paramagnetic resonance (EPR) increases with the In doping, resulting in an increase in the number of unpaired electrons, which is conducive to carrier transport. This work provides a new study In/GaN prepared by simple method for the light‐driven photocatalytic conversion of CO2 to high‐value‐added products.

AbstractColor reproduction through subtractive synthesis is achieved by combining the three primary colors cyan, magenta, and yellow (CMY). Three CMY electroactive polymers are selected, synthesized, and first, integrated into monochromatic electrochromic devices (pixels) similar to electrochemical cells. In order to develop innovative trichromatic devices, new pixel architectures are proposed and compared. In particular, the stacking of the three monochromatic CMY electrochromic devices in a single system is declined in the form of three different electrochemical cells, which differ in the nature and positioning of the counter‐electrode. Overall performances are finally evaluated in terms of range and ease of assembly. The architecture with common counter‐electrode is clearly the one that offers the best potential for the development of electrochromic devices to reproduce a wide range of colors.

AbstractConventional amine‐capped perovskite nanocrystals (A‐PNCs) often show microscopic fluctuation (blinking) of photoluminescence (PL) between bright and near‐background (dark) states. The transient dark phases spanning milliseconds (ms) to several seconds timescale typically owe to the non‐radiative (NR) fate of charge carriers in crystal defect states, limiting the PNC's efficiency in optoelectronics. A PL study of a novel trioctylphosphine (TOP) capped rhombic cuboctahedron‐shaped amine‐free (AF) PNC is presented, demonstrating their fascinating nonblinking nature. While oleylamine‐capped hexahedron A‐PNCs as a reference system show long dark states, their population is completely suppressed in ≈90% of AF‐PNCs with random large‐amplitude PL fluctuations several times above the background. The PL trajectories of AF‐PNCs primarily comprise constant power spectral densities (PSDs) which are unprecedented and deviate from power‐law distribution as observed for A‐PNCs and most of the other blinking nanocrystals. Such signature of PSDs and frame‐by‐frame intensity jump analysis indicate a fast (<<ms) timescale charge‐carrier dynamics governing the PL emission of AF‐PNCs, likely involving short‐lived metastable states. Besides, long‐term stability and suppressed dark phases in ≈70% AF‐PNCs even 90 days after the synthesis is noteworthy. Altogether the study provides exceptional optical characteristics of photostable amine‐free PNCs which would be attractive to exploit in commercial display applications.

AbstractThe mechanically and electrochemically stable and ionically conducting solid electrolyte interphase (SEI) is important for the stabilization of metal anodes. Since SEIs are originally absent in aqueous zinc metal batteries (AZMBs), it is very challenging to suppress water‐induced side reactions and dendrite growth of Zn metal anodes (ZMAs). Herein, a gradient‐structured and robust solid gradient SEI, consisting of B,O‐inner and F,O‐exterior layer, in situ formed by hydrated eutectic electrolyte for the homogeneous and reversible Zn deposition, is demonstrated. Moreover, the molar ratio of acetamide to Zn salt is modulated to prohibit the water activity and the hydrolysis of BF4− as well as to achieve high ionic conductivity owing to the regulation of the solvation sheath of Zn2+. Consequently, the eutectic electrolyte allows Zn||Zn symmetric cells to achieve a cycling lifespan of over 4400 h at 0.5 mA cm−2 as well as Zn||PANI full cells to deliver a high capacity retention of 73.2% over 4000 cycles at 1 A g−1 and to demonstrate the stable operation at low temperatures. This work provides the rational design for the hydrated eutectic electrolyte and the corresponding gradient SEIs for dendrite‐free and stable Zn anodes even under harsh conditions.

AbstractSolid‐state lithium‐ion batteries are widely accepted as the promising next‐generation energy storage technology due to higher energy density and improved safety compared to conventional lithium‐ion batteries with liquid electrolytes. Large‐area solid‐state electrolyte (SSE) films with adequate thickness control, improved ionic conductivity, and good interfacial contact can reduce internal resistance, increase the real energy density of batteries, and reduce manufacturing costs. Optimization of SSE properties at the particle scale and large‐scale preparation of SSE films are key to the development of high‐performance solid‐state lithium‐ion batteries and their industrialization. Therefore, this paper provides a comprehensive review of SSE, covering both particle‐level features like the effects of particle size, density, and air stability on the electrochemical performance, as well as four major routes for large‐scale preparation and relevant strategies for structural optimization of SSE films. In addition, the effects of large‐area SSE films on the electrochemical performance of solid‐state batteries and their applications in pouch solid‐state lithium‐ion battery systems are discussed in detail. Finally, the design principles of SSE particles and SSE films are summarized and the development direction of thin SSEs is envisaged.
