    Abstract: Changes in soil carbon (C) sequestration in grassland ecosystems have important impacts on the global C cycle. As such, it is important that researchers better understand the underlying mechanisms affecting soil C. Increasing evidence has shown that atmospheric nitrogen (N) deposition can cause dramatic changes in grassland soil C. It remains unclear whether herbivore grazing, a primary means to manage and utilize grassland resources, can regulate the effects of N deposition on soil C, and whether these effects are dependent on plant community diversity. Here, we examined the joint effects of herbivore grazing and N‐addition on soil organic C (SOC) stocks in two types of communities with low and high plant diversity respectively. Our results showed that the effects of N‐addition and its combination with herbivore grazing on grassland SOC were inconsistent in the two types of communities. In the low‐diversity community, N‐addition greatly decreased SOC stocks, while grazing significantly increased it. Additionally, the grazing‐induced increase in soil C stocks in the presence of N‐addition was so great that it completely counteracted the significant decline in SOC induced by N‐addition. However, in the high‐diversity community, we observed no effects of N‐addition on SOC and grazing increased SOC only in the absence of N‐addition and had no significant effect in the presence of N‐addition. Synthesis and applications . Our study suggests that increased N deposition can trigger a remarkable reduction in soil C sequestration in grasslands with low plant diversity, but that herbivore grazing can offset this decline, which may help to mitigate greenhouse gas emissions caused by atmospheric N deposition. As a result, we suggest that moderate herbivore grazing should be considered as an effective grassland management measure for maintaining and improving grassland soil C sequestration as the increasing global changes such as elevated atmospheric carbon dioxide, N deposition and biodiversity losses threat.

    Abstract: Glioblastoma is an aggressive type of brain cancer with an extremely poor prognosis. Additionally, the F‐box WD repeat‐containing protein 7 (FBXW7) is a component of the ubiquitin‐proteasome system that has been widely implicated in human cancers. In this study, we investigated the role and mechanism of FBXW7 in glioblastoma. FBXW7 expression was analyzed in normal and glioblastoma tissue samples using The Cancer Genome Atlas Glioblastoma Multiforme (TCGA‐GBM) database. Then, quantitative reverse transcription‐polymerase chain reaction (RT‐PCR) was used to examine mRNA expression, whereas, western blot analysis was conducted to determine protein levels of the samples. Furthermore, cell apoptosis was assessed using the Annexin V staining method, followed by flow cytometry analysis. Immunoprecipitation (IP) assay was conducted as well to test protein–protein interactions. Lastly, protein expression in tissues was examined by conducting immunohistochemistry (IHC). Results showed that the glioblastoma tissue samples displayed an FBXW7 downregulation compared with normal tissues. In vitro, the overexpression of FBXW7 in glioblastoma cells induced apoptosis, whereas, its knockdown displayed the opposite effect. Mechanistically, FBXW7 interacted with HDAC7 to promote HDAC7 ubiquitination, however, the overexpression of HDAC7 in glioblastoma cells blocked FBXW7‐induced apoptosis. Finally, FBXW7 and HDAC7 displayed an inverse correlation in glioblastoma tissues in vivo. Therefore, our data demonstrated an important function of FBXW7 in promoting glioblastoma apoptosis by interacting with HDAC7 and promoting HDAC7 ubiquitination.

    Abstract: Improvements in energy–water systems will necessitate fabrication of high‐performance separation membranes. To this end, interface engineering is a powerful tool for tailoring properties, and atomic layer deposition (ALD) has recently emerged as a promising and versatile approach. However, most non‐polar polymeric membranes are not amenable to ALD processing due to the absence of nucleation sites. Here, a sensitization strategy for ALD‐coating is presented, illustrated by membrane interface hydrophilization. Facile dip‐coating with polyphenols effectively sensitizes hydrophobic polymer membranes to TiO 2 ALD coating. Tannic acid‐sensitized ALD‐coated membranes exhibit outstanding underwater crude oil repulsion and rigorous mechanical stability through bending and rinsing tests. As a result, these membranes demonstrate outstanding crude oil‐in‐water separation and reusability compared to untreated membranes or those treated with ALD without polyphenol pretreatment. A possible polyphenol‐sensitized ALD mechanism is proposed involving initial island nucleation followed by film intergrowth. This polyphenol sensitization strategy enriches the functionalization toolbox in material science, interface engineering, and environmental science.

    Abstract: Although large amount of effort has been invested in combating thermal quenching that severely degrades the performance of luminescent materials particularly at high temperatures, not much affirmative progress has been realized. Herein, we demonstrate that the Frenkel defect formed via controlled annealing of Sc 2 (WO 4 ) 3 :Ln (Ln=Yb, Er, Eu, Tb, Sm), can work as energy reservoir and back‐transfer the stored excitation energy to Ln 3+ upon heating. Therefore, except routine anti‐thermal quenching, thermally enhanced 415‐fold downshifting and 405‐fold upconversion luminescence are even obtained in Sc 2 (WO 4 ) 3 :Yb/Er, which has set a record of both the Yb 3+ ‐Er 3+ energy transfer efficiency ( 〉 85 %) and the working temperature at 500 and 1073 K, respectively. Moreover, this design strategy is extendable to other hosts possessing Frenkel defect, and modulation of which directly determines whether enhanced or decreased luminescence can be obtained. This discovery has paved new avenues to reliable generation of high‐temperature luminescence.

    Abstract: Shape memory epoxy resin has a high potential for applications in various fields such as space deployable structures and actuators. In order to meet the requirements of application and extend the materials' service life, it is highly desirable to develop a shape memory epoxy resin with good properties of shape memory, reprocessing, and self‐healing. In this work, a shape memory epoxy resin based on the orientable biphenyl mesogen and the dynamic siloxane is fabricated successfully via anion ring‐opening polymerization. The resulting epoxy resin exhibits excellent shape memory performance, good reprocessing ability, good self‐healing property, and triple shape memory effect (triple‐SME).

    Abstract: Photothermal tumor therapy (PTT) and photoacoustic imaging (PA) have emerged as promising noninvasive diagnostic and therapeutic approaches for cancer treatment. However, the development of efficient PTT agents with high photostability and strong near‐infrared (NIR) absorption remains challenging. This study synthesizes three isoindigo‐based dual‐acceptor conjugated polymers (CPs) (P‐IIG‐TPD, P‐IIG‐DPP, and P‐IIG‐EDOT‐BT) via a green and nontoxic direct arylation polymerization (DArP) method and characterizes their optical, electrochemical, and NIR photothermal conversion properties. By incorporating two acceptors into the backbone, the resulting polymers exhibit enhanced photothermal conversion efficiency (PCE) due to improved synergy among conjugation length, planarity, and intramolecular charge transfer (ICT). The nanoparticles (NPs) of P‐IIG‐EDOT‐BT and P‐IIG‐DPP have a uniform size distribution around 140 nm and exhibit remarkable NIR absorption at 808 nm. In addition, P‐IIG‐EDOT‐BT and P‐IIG‐DPP NPs exhibit high PCEs of 62% and 78%, respectively. This study promotes the molecular design of CPs as NIR photothermal conversion materials and provides guidance for the development of novel dual‐acceptor CPs for tumor diagnosis and treatment.

    Abstract: The frequent incidence of postsurgical recurrence issues in papillary thyroid cancer (PTC) patients is a primary concern considering the low cancer‐related mortality. Previous studies have demonstrated that epithelial–mesenchymal transition (EMT) activation is closely related to PTC progression and invasion. In this study, we aimed to develop a novel EMT signature and ancillary nomogram to improve personalized prediction of progression‐free interval (PFI). Methods First, we carried out a differential analysis of PTC samples and pairwise normal thyroid samples to explore the differentially expressed genes (DEGs). The intersection of the DEGs with EMT‐related genes (ERGs) were identified as differentially expressed EMT‐related genes (DE‐ERGs). We determined PFI‐related DE‐ERGs by Cox regression analysis and then established a novel gene classifier by LASSO regression analysis. We validated the signature in external datasets and in multiple cell lines. Further, we used uni‐ and multivariate analyses to identify independent prognostic characters. Results We identified 244 prognosis‐related DE‐ERGs. The 244 DE‐ERGs were associated with several pivotal oncogenic processes. We also constructed a novel 10‐gene signature and relevant prognostic model for recurrence prediction of PTC. The 10‐gene signature had a C‐index of 0.723 and the relevant nomogram had a C‐index of 0.776. The efficacy of the signature and nomogram was satisfying and closely correlated with relevant clinical parameters. Furthermore, the signature also had a unique potential in differentiating anaplastic thyroid cancer (ATC) samples. Conclusions The novel EMT signature and nomogram are useful and convenient for personalized management for thyroid cancer.

    Abstract: High‐order compensation for the inductive coupling power transfer (ICPT) system is preferred due to its high design freedom and excellent coil current harmonics suppression capability. Especially, the good harmonics suppression capability is helpful to implement the synchronous wireless transfer of energy and data with a pair of data communication coils integrated into the energy transfer coils. Thus, on basis of THD 1 and THD 2 comparison for different high‐order compensation topologies, the LCC‐LC compensated ICPT system with load‐independent zero phase angle (ZPA) and constant voltage output is discussed in this paper. Compared with other high‐order compensation topologies with constant voltage output such as LC‐LC, LC‐LCC, and LCC‐LCC, the LCC‐LC has the advantages of ZPA operation with zero voltage switching and less secondary‐side components. For a given magnetic coupler, infinite feasible combinations of compensation parameters can make the system accomplish ZPA and the same output characteristics. Thus, efficiency optimization of the LCC‐LC compensated ICPT system can be investigated by configuring the optimal compensation parameters. To validate the theoretical analysis, especially the efficiency improvement, the experimental platform with 270 V input and 270 V/3 kW output is designed and built. The comparative experimental results for three different the compensation parameters show the optimized system can improve greatly conversion efficiency over the entire load range, especially under light load.

    Abstract: Ionic conductive hydrogel electrolyte is considered to be an ideal electrolyte candidate for flexible supercapacitor due to its flexibility and high conductivity. However, due to the lack of effective recycling methods, a large number of ineffective flexible hydrogel supercapacitors caused by some irreversible damages and dryness of hydrogel electrolyte are abandoned, which would induce heavy economic and environmental protection problems. Herein,a smart ionic conductive hydrogel (SPMA‐Zn: ZnSO 4 /sodium alginate/polymethylacrylic acid) is developed for flexible hybrid supercapacitor (SPMA‐ZHS). The SPMA‐Zn exhibits an excellent self‐healing ability and can recover its electrochemical performance after multiple mechanical damages. More importantly, it possesses an outstanding powder self‐healable property, which could easily regenerate the hydrogel electrolyte after powdering, and maintain stable electrochemical performance of SPMA‐ZHS. Besides, the SPMA‐ZHS displays excellent electrochemical performance with a wide and stable working voltage range of 0–2.2 V, high energy density of 164.13 Wh kg −1 at the power density of 1283.44 Wh kg −1 and good stability with a capacity retention of 95.3% after 5000 charge/discharge cycles at 10 A g −1 . The strategy in this work would provide a new insight in exploring flexible hydrogel electrolyte‐based supercapacitor with good sustainability and high energy density for flexible wearable electronic devices.

    Abstract: Electrocatalytic nitrogen reduction reaction (NRR) and hydrogen evolution reaction (HER) are intriguing approaches to nitrogen fixation and hydrogen production under ambient conditions, given the need to discover efficient and stable catalysts to light up the “green chemistry” future. However, bottlenecks are often found during N 2 /H 2 O activation, the very first step of NRR/HER, due to energetic electron injection from the surface of electrocatalysts. It is reported that the bottlenecks for both NRR and HER can be tackled by engineering the energy level via low‐valent transition‐metal doping, simultaneously, where rhenium disulfide (ReS 2 ) is employed as a model platform to prove the concept. The doped low‐valent transition‐metal domains (e.g., Fe, Co, Ni, Cu, Zn) in ReS 2 provide more active sites for N 2 /H 2 O chemisorption and electron transfer, not only weakening the NN/OH bonds for easier dissociation through proton coupling, but also elevating d ‐band center toward the Fermi level with more electron energy for N 2 /H 2 O reduction. As a result, it is found that iron‐doped ReS 2 nanosheets wrapped nitrogen‐doped carbon nanofiber (Fe‐ReS 2 @N‐CNF) catalyst exhibits superior electrochemical activity with eightfold higher ammonia production yield of 80.4 µg h −1 mg −1 cat. , and lower onset overpotential of 146 mV and Tafel slope of 63 mV dec −1 , when comparing with the pristine ReS 2 .
