Data from: The preparation and characterization of uniform nanoporous structure on glass
<p>A novel fabrication method of uniform porous structures on the glass surface is proposed. The hydrofluoric acid fog formed by air-jet atomization etches the glass surface to fabricate nanoporous structure (NPS) on glass surface. This NPS shows the enhanced average light transmittance of ~92.9% and the superhydrophilic property with a contact angle less than 1° which presents an excellent anti-fog property. Passivated by fluorosilane, the NPS shows nearly the superhydrophobic property with a contact angle of 141.2°. This fabrication method has shown promising application prospects due to its simplicity, low cost and efficiency, which can be easily applied to large-scale industrial production.</p>
Synthesis of a novel amphoteric copolymer and its application as a dispersant for coal water slurry preparation
<p>In this work, a novel amphoteric copolymer was synthesized via free radical polymerization, named Poly(sodium p-styrenesulfonate–co-acrylic acid-co-diallyldimethylammonium chloride) (P(SS-co-AA-co-DMDAAC)). Afterwards, P(SS-co-AA-co-DMDAAC) was explored for use as a dispersant in coal water slurry (CWS) preparation. The structure of P(SS-co-AA-co-DMDAAC) was verified by Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance (NMR). The synthetic conditions were optimized as the feed ratio of AA to SS was 1:1 (for Yulin coal) or 1.5:1 (for Yili coal), and DMDAAC dosage was 4.0 wt% (for Yulin coal) and 6.0 wt% (for Yili coal) toward total monomers. The performances of P(SS-co-AA-co-DMDAAC) as a dispersant for CWS were evaluated by various technologies, such as apparent viscosity, Zeta potential, static stability and contact angle measurements. The results revealed that the optimized dosage of P(SS-co-AA-co-DMDAAC) in CWS preparation was 0.3 wt% and 0.4 wt% for Yulin coal and Yili coal respectively. In this optimum condition, CWS prepared using P(SS-co-AA-co-DMDAAC) as dispersant showed a typical shear thinning behavior and excellent stability, which are desired in industry. The rheological models also confirmed the pseudo-plastic characteristics of CWS. Finally, as compared to the widespread used anionic dispersant Poly(sodium p-styrenesulfonate) (PSS), P(SS-co-AA-co-DMDAAC) developed in this work exhibited better slurry making performance. Introduction of cationic functional groups promoted the adsorption of dispersant, which further enhanced the electrostatic repulsion among coal particles. Accordingly, the viscosity of CWS decreased and static stability enhanced.</p>
The integration of sensory feedback in the modulation of anuran landing preparation
<p class="MsoBodyText">Controlled landing requires preparation. Mammals and bipedal birds vary how they prepare for landing by predicting the timing and magnitude of impact from the integration of visual and non-visual information. Here we explore how an animal that moves primarily through hopping, <i>Rhinella marina</i>, the cane toad, integrates sensory information to modulate landing preparation. Earlier work suggests toads may modulate landing preparation using predictions of impact timing and/or magnitude based on non-visual sensory feedback during takeoff rather than visual cues about the landing itself. Here we disentangled takeoff and landing conditions by hopping toads off platforms of different heights and measured electromyographic (EMG) activity of an elbow extensor, <i>m. anconeus</i>, and used high-speed motion capture to quantify whole body and forelimb kinematics to test how toads integrate visual and non-visual information in landing preparation. We asked two questions: 1) when they conflict, do toads correlate landing preparation with takeoff or landing conditions? And 2) for hops with the same takeoff conditions, does visual information alter the timing of landing preparation? We found that takeoff conditions are a better predictor of the onset of landing preparation than landing conditions, but that visual information is not ignored. When hopping off higher platforms, toads start to prepare for landing later when takeoff conditions are invariant. This suggests that, unlike mammals, toads prioritize non-visual sensory feedback about takeoff conditions to coordinate landing, but that they do integrate visual information to fine-tune landing preparation.</p>
Facile preparation of high conductive silver electrodes by dip-coating followed by quick sintering
<p>With polyol-synthesized silver nanoparticles (AgNPs) as raw materials, the silver electrodes with high conductivity were fabricated via dip-coating method followed by sintering process, and the effects of dip-coating and sintering process on the conductivity and surface roughness of silver electrodes were investigated in detail. The silver film with a thickness of 1.97 μm and a roughness of about 2 nm can be prepared after dip-coated at a pulling rate of 500 μm·s<sup>-1</sup> for 40 coating times. The non-conductive dip-coated silver films are transformed into conductive silver electrodes after conventional sintering in muffle oven, infrared sintering and microwave sintering, respectively. Compared with high sintering temperature and long sintering time of conventional sintering and infrared sintering, microwave sintering can achieve the quick sintering of silver films to fabricate high conductive silver electrodes. The silver electrodes with a sheet resistance of 0.75 Ω·sq<sup>-1</sup> and a surface roughness of less than 1 nm can be obtained after microwave-sintered at 500 W for 50 s. The adjustable dip-coating method followed by quick microware sintering is an appropriate approach to prepare high conductive AgNPs based electrodes for organic light-emitting diode (OLED) or other devices.</p>
Data from: Preparation and structure of SiOCN fibers derived from cyclic silazane/PAA hybrid precursor
Ceramic matrix composite (CMC) materials have been considered a desired solution for lightweight and high temperature applications. Simultaneously, among all different CMC reinforcements, Polymer-Derived Ceramic (PDC) fibers have gained attention for the intrinsic thermal stability and mechanical strength with simple and cost-effective synthesis techniques. Here, carbon-rich silicon oxycarbide (SiOC) fibers were synthesized via hand-drawing and polymer pyrolysis of a hybrid precursor of 1,3,5,7-tetramethyl-1,3,5,7-tetravinyl-cyclotetrasilazane (TTCSZ) and polyacrylic acid (PAA). The type of silazane reported in this work is considered as a major precursor for SiCN, however it is unspinnable, due to its unfavorable physical properties (low viscosity) and chemical structure (cyclic rather than linear structure). The introduction of PAA to TTCSZ to create a hybrid precursor remarkably improved spinnability of the silazane and should be widely applicable to other unspinnable PDC preceramic polymers. Investigations on structural and compositional development of the fibers were mainly conducted via Raman spectroscopy, Fourier-Transform InfraRed spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), Nuclear Magnetic Resonance (NMR) and ThermoGravimetric Analysis (TGA) to determine spinnability, free carbon content, cross-linking and pyrolysis behavior of the fibers, respectively.
Data set of CA1 pyramidal cell models using an intact whole hippocampus preparation
<p>The frequency-current (f-I) profiles of pyramidal cells are presented. Each .abf file contains the f-I curve data for the respective cell (as labelled PYR1, PYR2, PYR3 and PYR4 for Pyramidal cell 1, Pyramidal cell 2, Pyramidal cell 3 and Pyramidal cell 4). That is, they contain the cell's response to the application of a series of depolarizing current steps of 1 s duration while the cells are held in current clamp, as well as the current clamp data itself. Each recording is 2 s total. Amplitudes of the input were increased incrementally with step sizes of 10 pA for PYR1, PYR3, and PYR4, and a step size of 25 pA for PYR 2. PYR1 first spikes on the 5th of 30 steps with 38.7 pA of depolarizing input. PYR2 first spikes on the 3rd of 13 steps with 1.2 pA of input. PYR3 first spikes on the 7th of 34 steps with 62.0 pA of input, and PYR4 first spikes on the 7th of 30 steps with 12.1 pA of input.</p>
Data set of CA1 pyramidal cell recordings using an intact whole hippocampus preparation, including recordings of rebound firing (V2)
<p>The frequency-current (f-I) profiles and an example of rebound firing of pyramidal cells are presented. Four .abf files contain the f-I curve data for the respective cell (as labelled PYR1, PYR2, PYR3 and PYR4 for Pyramidal cell 1, Pyramidal cell 2, Pyramidal cell 3 and Pyramidal cell 4). That is, they contain the cell's response to the application of a series of depolarizing current steps of 1 s duration while the cells are held in current clamp, as well as the current clamp data itself. Each recording is 2 s total. Amplitudes of the input were increased incrementally with step sizes of 10 pA for PYR1, PYR3, and PYR4, and a step size of 25 pA for PYR 2. PYR1 first spikes on the 5th of 30 steps with 38.7 pA of depolarizing input. PYR2 first spikes on the 3rd of 13 steps with 1.2 pA of input. PYR3 first spikes on the 7th of 34 steps with 62.0 pA of input, and PYR4 first spikes on the 7th of 30 steps with 12.1 pA of input. In the .abf file labelled PYR5_rebound, an example of rebound firing of a pyramidal cell following hyperpolarizing input is given. While the cell was held at -52 mV in current clamp, as series of 1 s hyperpolarizing steps (10 steps, 25 pA increments) were used to record the post- hyperpolarization rebound spiking. For the figure showing this rebound spiking (Figure 1), the first two hyperpolarizing steps and the respective firing are shown. For visualization purposes, the spike artifact in the current clamp input trace was removed and replaced with the mean current in the Figure. </p>

Differentially expressed genes in berries and rachis of berry shrivel grape clusters used to prepare figures for a review
<p>Grapevine berry shrivel is a ripening disorder leading to significant economic losses in the worldwide wine and table grape industries. Sugar accumulation stops early after ripening onset accompanied with cell death in berreis and subtending pecicels and rachis finally resulting in berry shrinkage. To date, the triggers of BS remain unknown. The dataset supports figures prepared for an review which aims to summarize and critically discuss the current knowledge. Data are expressed as differentially expressed genes obtained from grape berries samples collected at six developmental stages (pre- until post-veraison) analysed with RNASeq and two pooled samples (pre- and BS symptomatic) from the rachis analyzed with a microarray study. Extracted information focus on primary metabolic processes including sugar transport and metabolism, organic acid metabolism, stress signaling and cell as well as cell wall organisation. Data are mean values of three biological represent and presented as log2 fold changes including statistical information. A meta-data sheet provides the most relevant information and references. </p>
