具有原子层厚度的氧化物磁性材料拥有将二维磁性应用到下一代自旋电子学新兴领域的巨大潜力,引起了研究者的广泛关注.因此,实现二维单层氧化物磁、电性能的磁场和电场调控,为未来低功耗自旋电子器件提供了广阔应用前景.然而,电场调控二维单层氧化物磁性报道很少.本工作利用离子液体门电压进行质子掺杂,实现了对二维单层氧化物(SrRuO_(3))_(1)/(SrTiO_(3))_(N)(N=1,3)磁、电性能的电场可逆调控.随着质子掺杂浓度提高,在(SrRuO_(3))_(1)/(SrTiO_(3))_(1)中观察到了从铁磁金属到反铁磁绝缘态相变,并伴随着磁各向异性的转变.理论分析表明,质子掺杂引起的能带结构改变是结构和磁、电性能相变的主要原因.同时,SrTiO_(3)层起到质子筛作用,在质子的演化过程中扮演重要角色.该研究通过电场调控二维单层氧化物的结构和物性,为实现材料的多功能性提供了重要思路,同时也为实现低功耗功能器件提供了应用潜力.

Lewis-base polymers have been widely utilized as additives to act as a template for the perovskite nucleation/crystal growth and passivate the under-coordinated Pb2+ ***,it is uncovered in this work that the polymer on the perovskite grain boundaries would significantly hinder the charge transport due to its low conductivity,which brings about free carrier recombination and photocurrent *** circumvent this issue while fully exploiting the benefits of polymers in passivating the trap states in perovskite,we incorporate highly conductive multiwall carbon nanotubes(CNTs) with Lewis-base polymers as coadditives in the perovskite *** the CNTs with-COOH group enables a selective hole-extraction and charge transport from perovskite to the hole transporting materials(HTM).By studying the charge transporting and recombination dynamics,we revealed the individual role of the polymer and CNTs in passivating the trap states and facilitating the charge transport,*** a result,the perovskite solar cells(PSCs) with polymer-CNTs composites exhibit an impressive PCE of 21.7% for a small-area device(0.16 cm2) and 20.7% for a large-area device(1.0 cm2).Moreover,due to the superior mechanical flexibility of both polymer and CNTs,the polymer-CNTs composites incorporation in the perovskite film encourages the fabrication of flexible PSCs(f-PSCs) with an impressive PCE of 18.3%,and a strong mechanical durability by retaining 80%of the initial PCE after 1,000 times *** addition,we proved that the selection criteria of the polymers can be extended to other long-chain Lewis-base polymers,which opens new possibilities in design and synthesis of inexpensive material for this tactic towards the fabrication of high performance large-area PSCs and f-PSCs.

To increase the color fastness to sunlight of dyed meta-aramid, meta-aramid fabrics are dyed with vat dyes with excellent color fastness to sunlight. Optimization was achieved through conducting the suspension dyeing method and the leuco-acids dyeing method. The effects of dye concentration, thiourea dioxide concentration, reduction temperature, dyeing temperature and dyeing time on dyeing performance were studied. The dyeing process is as follows: vat dye 60 g/L, thiourea dioxide 5 g/L, reduction was carried out at 60°C, followed by dyeing at 130°C for 60 minutes. The results show that vat dyeing can deal with the issue of poor color fastness to sunlight of meta-aramid fiber, and leuco-acid dyeing with vat dyes can improve meta-aramid fiber color fastness to sunlight, up to 3-4. © 2019 textile Bioengineering and Informatics Symposium Proceedings 2021 - 14th textile Bioengineering and Informatics Symposium, TBIS 2021.

Introducing multiple active sites and constructing heterostructure are efficient strategies to develop high-performance electrocatalysts. Herein, two-dimensional heterostructure NiFeP@FeOOH nanosheets supported by nickel foam are equipped by hydrothermal-phosphorization-electrodeposition process. The synthesis of self-supporting heterostructure NiFeP@FeOOH nanosheets on the NF increased the specific surface region, bimetallic phosphide realized rapid charge transfer, improved the electron transfer rate. The introduction of FeOOH and the construction of heterostructure realized the synergistic effect among the components, and the surface active sites are abundant. In situ Raman spectroscopy showed that the excellent oxygen evolution reaction (OER) performance was due to the reconstruction-induced hydroxyl oxide, which achieved a multi-active site reaction. The NiFeP@FeOOH/NF electrocatalytic activity is significantly improved. The findings indicate that in 1.0 M KOH alkaline solution, NiFeP@FeOOH/NF showed an OER overpotential of 235 mV at 100 mA cm-2, a Tafel slope of 46.46 mV dec-1 and worked stably at 50 mA cm-2 for 80 h. This research proves the importance of constructing heterostructure and introducing FeOOH are of great significance to the study of the properties of OER electrocatalysts. © 2024, The Authors.

Metal Alkoxides: A new Type of Reversible Anode materials for Stable and High-Rate Lithium-Ion Batteries

Metal-organic compounds have attracted significant attention for lithium-ion battery (LIB) anodes. However, their practical application is severely hindered by the poor structure stability and sluggish Li+ reaction kinetics. Here, we proposed a new type of metal-organic compound, metal alkoxides, for high-performance LIBs. A series of metal-alkoxide/graphene composites with different transition metal centers and alkoxide anions are prepared to investigate the structural stability, Li-storage ability, and Li+ diffusion kinetics. The results reveal that the metal centers and alkoxide anions have significant influence on the structural stability, molecular weight, and electronic structures, which are highly related to the Li-storage performance. Among them, Co-EG/rGO (EG represents the ethylene glycol anion) delivers the best performance involving high specific capacity (975 mAh g-1 at 0.2 A g-1), excellent rate capability (400.8 mAh g-1 at 10 A g-1), and stable cycling performance (86.8% capacity retention after 600 cycles) due to its stable structure, smaller molecular weight, and favorable electronic structure. Moreover, the Li-storage mechanism and solid electrolyte interphase (SEI) evolution of the Co-EG/rGO electrode are studied in detail through multiple ex-situ/in-situ characterizations. This work provides a new type of metal alkoxide anode material for high-rate and long-life LIBs toward practical energy applications. © 2024, The Authors. All rights reserved.

The authors regret the following errors in the published article: In the originally published supplementary information document, Fig. S1a, S5c and S6d were images of the same sample obtained at optimal conditions. In order to avoid misleading readers, the original Fig. S5c and S6d have been replaced by new images captured at different places of the same sample. In addition, an error was found in the Fig. S6 caption: the PVP amount for both Fig. S6a and b should be 0 g. The corrected versions of Fig. S5 and S6 are shown below. In the "Results and discussion" section of the published article, on page 1662 of the pdf, the related description of Fig. S6 should be corrected as follows: "Numerous scattered flakes and only a few a-Co(OH)2 crabapples were obtained without the addition of PVP (Fig. S6a and b, ESI)." The supplementary information document has been updated with these changes. (Figure presented) In Fig. 2 in the published article, an error occurred when assembling the images: Fig. 2b and e were inadvertently swapped. The accompanying calculations and the following descriptions used the correct data and thus are not affected. The corrected Fig. 2 is shown in this notice. Related to this, on page 1664 of the pdf, the related text remains almost constant with some fluctuations..." should be replaced with remains almost constant despite fluctuations from 13.6-14.4 GHz...". In addition, "For sample M30, a sharp decrease of in the frequency range of 12-18 GHz occurs while the corresponding shows a resonance peak,. . ." should be replaced with "For sample M30, a decrease of occurs while the shows a resonance peak in the frequency range of 12-18 GHz,. . .". In addition, on page 1665 of the pdf, the sentence "The SBET for hierarchical porous Co/C crabapples is 68.4 m2 g-1" should be corrected to "The SBET for hierarchical porous Co/C crabapples is 64.4 m2 g-1" after rechecking the raw data.
