In the context of human active response to exponentially increasing data volumes, memristors have emerged as a focal point in systematic problem‐solving approaches. Particularly, organic memristors, characterized by excellent scalability, flexibility, and 3D stacking capabilities, have shown its tremendous potential in innovative electronic applications. However, the modulation of molecular assembly and interface interaction at the electrode surface poses a challenging task, despite their crucial role in determining the memristive performance. Herein, a collaborative method involving hydrophobic molecular design and interface engineering is proposed to generate high‐quality nanofilms with optimal photoelectric and electrochemical properties. By subjecting the bottom electrode to O2 plasma treatment and chemical modification using a hydrophobic ionic liquid poly(diallyldimethylammonium) bis(trifluoromethanesulfonyl)imide (PTFSI), the hydrophobic compound DN demonstrates exceptional affinity and stronger intermolecular interactions with the electrode surface. Consequently, the two‐terminal device array comprising Al/DN@PTFSI/ITO exhibits robust non‐volatile write‐once‐read‐many times (WORM) memory behavior, resulting in a tripling production yield from 30% to 92% along with a lower threshold voltage of 1.5 V, higher ON/OFF current ratio of 103 and excellent stability. This study presents a versatile approach to optimize the film assembly and material/electrode interface, thereby accelerating the development of organic memristors toward future applications.

Summary: Senescence accompanying browning is the main factor that reduces the sensory and nutritional quality of cherries during storage. In the present study, we analysed the effects of sodium nitroprusside (SNP) treatment with 0, 200, 400, and 600 μm on delaying the senescence and browning of cherries preserved at 4 °C for 30 days. Results suggested that 400 μm SNP treatment significantly enhanced the antioxidant capacity and maintained better fruit quality. Specifically, SNP treatment inhibited the activity of polyphenol oxidase, delayed the browning of cherry flesh and reduced soluble quinone content. Meanwhile, the peroxidase (POD), catalase and phenylalanine ammonia‐lyase (PAL) activities were enhanced by SNP treatments, while reactive oxygen species accumulation and membrane lipid peroxidation were alleviated. In addition, SNP treatment increased the accumulation of phenols, flavonoids and anthocyanins, which also enhanced the 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) scavenging capacity in cherries. Therefore, our results support SNP treatment to be a potential approach to delay flesh browning and maintain the sensory and nutritional qualities of cherries. [ABSTRACT FROM AUTHOR]

Sulfur dioxide (SO2) fumigation has been widely used to control pathogens and maintain the postharvest quality of table grapes. However, the effective dosage of SO2 treatment is close to causing bleaching damage on fruits. Further, the SO2 potential residue is a risk to human health. In this study, the dominant pathogens in "red globe" grapes during cold storage (0 and 10°C) were identified as Botrytis cinerea, Alternaria alternata, and Penicillium expansum, while Aspergillus niger was dominant pathogen when the grapes were stored at room temperature (25°C). The isolated dominant pathogens were effectively suppressed by SO2 ranging from 500 μl L−1 to 800 μl L−1, but bleaching spots were observed in grapes when SO2 was applied at 800 μl L−1. To reduce the SO2 residue, the fungicides dimethomorph and thiophanate‐methyl were respectively sprayed to control the epiphytic pathogens during the development of grape berries. In addition, the reduced microbial population contributed by fungicide treatments remitted the original density of postharvest microbial growth. The postharvest automated intermittent SO2 fumigation at 500 μl L−1 was subsequently integrated to control the microbial activities. In addition, SO2 maintained the soluble solid content and titratable acid content, which were 22% and 75% higher than the control (p <.05) on 120 days of storage. The inhibition percentage against dominant fungal pathogens by preharvest fungicides spray was approximately 30%, while the postharvest intermittent SO2 fumigation contributed about 50%. We investigated the suppression role of preharvest and postharvest combined treatment for the grapes, which was concluded as a promising application to reduce decay and extend the shelf life of "red globe" grapes.

This study proposes the construction of porous nanomaterial (HOFs@Fe3+) which anchors non‐noble metal ions Fe3+ onto nanoscale rod‐like hydrogen‐bonded organic frameworks (HOFs) by electrostatic and coordination interactions. The high specific surface area and the abundance of hydrogen‐bond adsorption active sites in pore structure of HOFs@Fe3+ facilitate strong interactions with the double OH in bisphenol A (BPA), resulting in the highest saturation adsorption of BPA that has been reported so far (452 mg g‐1). In addition, the ordered conjugate stacking framework structure and hydrogen bond of HOFs@Fe3+ and the variable valence properties of Fe3+ create new pathways for efficient separation of photogenerated carriers. The results show that HOFs@Fe3+ can completely adsorb and photodegrade 50 ppm BPA within 20 min, owing to the abundant hydrogen bond that acts both as adsorption sites to accelerate the mass transfer process and as catalytic sites to ensure adsorption and photodegradation can be matched synergistically. Meanwhile, the efficiency of photocatalytic H2 production by HOFs@Fe3+ reaches 21.55 mmol g‐1 h‐1 with non‐noble metal Fe3+ as co‐catalyst. This tri‐functional material with high adsorption capacity, high photodegradation efficiency, and high photocatalytic H2 production activity can be successfully used to solve the long‐standing conflict between environment and energy.

In the era of big data and artificial intelligence (AI), advanced data storage and processing technologies are in urgent demand. The innovative neuromorphic algorithm and hardware based on memristor devices hold a promise to break the von Neumann bottleneck. In recent years, carbon nanodots (CDs) have emerged as a new class of nano‐carbon materials, which have attracted widespread attention in the applications of chemical sensors, bioimaging, and memristors. The focus of this review is to summarize the main advances of CDs‐based memristors, and their state‐of‐the‐art applications in artificial synapses, neuromorphic computing, and human sensory perception systems. The first step is to systematically introduce the synthetic methods of CDs and their derivatives, providing instructive guidance to prepare high‐quality CDs with desired properties. Then, the structure–property relationship and resistive switching mechanism of CDs‐based memristors are discussed in depth. The current challenges and prospects of memristor‐based artificial synapses and neuromorphic computing are also presented. Moreover, this review outlines some promising application scenarios of CDs‐based memristors, including neuromorphic sensors and vision, low‐energy quantum computation, and human–machine collaboration.

Multidrug and toxic compound extrusion (MATE) transporter proteins are a class of secondary transporter proteins that can transport flavonoids. Anthocyanins, a kind of flavonoid, are important secondary metabolites widely found in higher plants; they determine the flower color of most angiosperms. TT12 in Arabidopsis was the first MATE protein identified to be involved in flavonoid transport. Petunia (Petunia hybrida) is an important ornamental plant and is one of the ideal plants for studying plant flower color. However, there are few reports on anthocyanin transport in petunia. In this study, we characterized a homolog of Arabidopsis TT12 in the petunia genome, PhMATE1, that shares the highest amino acid sequence identity with Arabidopsis TT12. PhMATE1 protein contained 11 transmembrane helices. PhMATE1 showed a high transcription level in corollas. The silencing of PhMATE1 mediated by both virus‐induced gene silence and RNA interference changed flower color and reduced anthocyanin content in petunia, suggesting that PhMATE1 is involved in anthocyanin transport in petunia. Furthermore, PhMATE1 silencing downregulated the expression of the structural genes of the anthocyanin synthesis pathway. The results of this study supported the hypothesis that MATEs are involved in the sequestration of anthocyanins during flower color formation. [ABSTRACT FROM AUTHOR]

Anthocyanins widely exist in plants and they are important pigments for color of petals and fruits. They are produced through a multi‐step pathway controlled by transcription factor complexes. The anthocyanin skeleton modification is the last reaction in the anthocyanin synthesis pathway, which improves the stability of anthocyanins. Acylation modification is an important modification of anthocyanins. However, the identification and function of anthocyanin acyltransferase genes and their expression regulation are rarely reported. In this study, we identified the petunia anthocyanin acyltransferase gene, PhAAT1. PhAAT1 is located in the cytoplasm and PhAAT1 silencing changed flower color and reduced the stability of anthocyanin. Metabolomics analysis showed that PhAAT1 silencing led to the reduction of p‐coumaroylated and caffeoylated anthocyanins. In addition, PhAAT1 was positively regulated by the MYB transcription factor, PhAN2, which directly interacts with the promoter of PhAAT1. [ABSTRACT FROM AUTHOR]

Organic semiconductor devices with low energy consumption and excellent stability are highly desirable. Controlling the intermolecular alignment orientation by designing the molecular structure or optimization of the film preparation process is an alternative way to achieve this goal. In this paper, a new idea was proposed to realize the formation of an aligned monomolecular layer and multimolecular layer thin films on the electrode substrate by controlling the surface pressure of molecular layer on the liquid surface by LB technology. An amphiphilic π‐conjugated D−A molecule was synthesized, and the influence of spin coating and LB technology on intermolecular ordered stacking in the film and the electrical memory performance were investigated. The results demonstrated that the film fabricated by LB technology has some advantages compared with that fabricated by spin‐coating method, such as higher crystallinity, lower surface roughness and better‐organized monomolecular and multimolecular layer, which significantly promoted the performance of the electrical memory device with lower power consumption and longer stability.
