Spin crossover (SCO) iron (II) coordination compounds in the form of nanohybrid SCO@SiO2 particles were prepared using a reverse micelles technique based on TritonX-100/cyclohexane/water ternary system. Tetraethyl orthosilicate (TEOS) acts as precursor both SiF62− counter-anion and SiO2 to obtain Fe(NH2trz)3(BF4)2−x(SiF6)x/2@SiO2 nanoparticles with different sizes morphologies while modifying TEOS concentration reaction time. The adjustable mixed-anion strategy leads range quite scarce...

Soft robotic hands with integrated sensing capabilities hold great potential for interactive operations. Previous work has typically focused on integrating sensors fingers. The palm, as a large and crucial contact region providing mechanical support sensory feedback, remains underexplored due to the currently limited density interaction Here, we develop sensorized hand that integrates high-density tactile dexterous soft fingers, cooperative palm-finger strategies. palm features compact...

A pure mixed-anion Fe(NH2trz)3(BF4)(SiF6)0.5 spin crossover complex is obtained implementing a solid-liquid post synthetic modification approach from the Fe(NH2trz)3(BF4)2 parent complex. This method allows obtaining highly crystalline powder samples incorporating homogeneous micrometric (1 μm long) rod-shaped particles. compound presents an abrupt behaviour with narrow (10 K) hysteresis loop centred just above room temperature (320 which makes it very interesting for future integration into...

We used stereolithography to print polymer nanocomposite samples of stimuli-responsive spin crossover materials in the commercial photo-curable printing resins DS3000 and PEGDA-250. The thermomechanical analysis SLA-printed objects revealed not only expected reinforcement by introduction stiffer SCO particles, but also a significant mechanical damping, as well sizeable linear strain around transition temperatures. For highest accessible loads (ca. 13-15 vol.%) we measured transformation...

T cells rewire their metabolic activities to meet the demand of immune responses, but how coordinate response by regulators in activated is unknown. Here, we identified autocrine VEGF-B as a regulator control lipid synthesis and maintain integrity mitochondrial inner membrane for survival cells. Disruption signaling reduced cardiolipin mass, resulting damage, with increased apoptosis memory development. The addition or modulating improved cell fitness survival. Autocrine through GA-binding...

Interfacial chemistry plays a crucial role in determining the electrochemical properties of low-temperature rechargeable batteries. Although existing interface engineering has significantly improved capacity batteries operating at low temperatures, challenges such as sharp voltage drops and poor high-rate discharge capabilities continue to limit their applications extreme environments. In this study, an energy-level-adaptive design strategy for electrolytes regulate interfacial Li||graphite...

The efficient use of coal resources and the safe operation coal-fired boilers are hindered by high-temperature corrosion caused corrosive sulphur components.

Abstract Our previous studies show that the mitotic phosphorylation of SUMO-specific protease 3 (SENP3) can inhibit its de-SUMOylation activity in G2/M phase cell cycle. Inhibition SENP3 plays a critical role correct separation sister chromatids mitosis. The mutation causes chromosome instability and promotes tumorigenesis. In this study, we find tumor cells suppress growth immune-competent mouse model. We further detect an increase CD8 + T infiltration tumors, which is essential for...

Graph Neural Networks (GNNs) are one of the prominent methods to solve semi-supervised learning on graphs. However, most existing GNN models often need sufficient observed data allow for effective and generalization. In real-world scenarios where complete input graph structure node labels might not be achieved easily, would encounter with severe performance degradation. To address this problem, we propose WSGNN, short weakly-supervised neural network. WSGNN is a flexible probabilistic...

Two Cu/ZrO2 catalysts defect with different microenvironments and electronic structures (CZ-ag-70 CZ-va catalysts) were synthesized by the same oxalic-acid-complexation-based method but heat-treatment methods, they used to catalyze hydrogen-transfer reaction between 5-hydroxymethylfurfural (HMF) isopropanol. The structure–activity relationship of each catalyst was analyzed, found have an important influence on product reaction. CZ-ag-70 rich in Cuδ+- [[EQUATION]]interfacial sites (the...

High-resistance ground faults are difficult to detect with existing ultrahigh voltage direct current (UHVDC) transmission fault detection systems because of their low sensitivity.
