Data from: Facile fabrication of fluoro-polymer self-assembled ZnO nanoparticles mediated, durable and robust omniphobic surfaces on polyester fabrics
<p>Omniphobic surfaces have been widely used in many applications, especially due to their self-cleaning property. Omniphobicity of a surface is directly interpreted by measuring the contact angle that it makes with a liquid of interest. In this study, polyester fabric was made omniphobic with a measured water contact angle (WCA) of 152° by reducing the surface free energy of the fabric surface via the polymerization of 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate(TDM) on a ZnO seed layer. The fabrics with and without the seed layer were characterized using various analytical techniques. The WCA of the fabric with the seed layer was 153° compared to 142° of the fabric without the seed layer. The treated fabric made a contact angle of 132° with SAE 40 motor oil indicating its oleophobicity while non-treated fabric made no contact angle. In addition to that, the treated fabric is omniphobic against milk tea, coffee, coconut oil, and ethanol. The morphological analysis using scanning electron microscopy (SEM) of the treated and non-treated fabrics revealed that the particle size of the seed layer applied fabric was ranging from 100-300 nm and upon the TDM application it became less than 100 nm. Elemental analysis by EDS showed the presence of fluorine and FT-IR analysis confirmed the polymerization of TDM. The polymerization of fluoropolymer was further confirmed by TGA and DSC analyses. The contact angle of the surface-modified fabric remained unchanged even after 1.5 h washing and 50 cycles of abrasion. The modified fabric is robust and no change was observed in the colour of the fabric during the process. More importantly the preparation method of the fabric is simple, low cost and quick.</p>
The role of shear fabric in controlling breakdown processes during laboratory slow slip events
<p>Understanding the physical mechanisms at the origin of slow slip events has been proven a very challenging task. In particular little is known on the role of fault heterogeneity during slow slip. In this study we provide evidence that fault fabric controls slip velocity time histories during slow slip events generated in the laboratory under the specific boundary condition of imposing a stiffness ratio K=k/k<sub>c</sub>~1. We have performed experiments using a double-direct biaxial shear apparatus and two different fault gouges, homogeneous quartz powder and heterogeneous anhydrite/dolomite mixture. We measure fine details of fault slip to resolve the slip velocity time history and volumetric deformation that, coupled with an analysis of the resulting microstructure, allow us to infer the mechanical processes at play. Our results show that slow slip events can be generated for both fault gouges when k~k<sub>c</sub> with similar values of breakdown work. The shear fabric exerts a strong influence during the co-seismic breakdown stage of instabilities. In quartz, where most of the slip occurs on a localized (1 µm) slipping surface, the peak slip velocity is attained near the final stage of friction breakdown and therefore a relevant amount of the mechanical work is absorbed during slip acceleration to peak slip velocity. In anhydrite/dolomite mixture, the peak slip velocity is suddenly reached after a relatively small drop in friction, accompanied by fault dilation, implying that most of the mechanical work is absorbed during slip deceleration. For anhydrite/dolomite mixture these results are likely related to heterogeneous slip distribution along the observed foliation. Taken together these observations suggest that the mechanics of slow slip events depends on shear zone fabric. The slip velocity function contains the necessary dynamic information to characterize the evolution of shear stress.</p> <p>The data are uploaded are structured as follow:</p> <p>1) a .txt file of the datafile that is recorded from the machine (raw data)</p> <p>2) a reduction file (_r) that is used to elaborate the raw data</p> <p>3) a file in .txt format containing the elaborated data (data_rp) </p> <p>The data are analyzed using rawPy that can be found at <a href="https://github.com/marcoscuderi/rawPy">https://github.com/marcoscuderi/rawPy</a></p> <p>For any additional information please do not hesitate to contact the corresponding author Marco Maria Scuderi at marco.scuderi@uniroma1.it.</p>

FIB-tomography data of porous Zr-oxide fabricated with varying sintering conditions
<p>This dataset contains 3D data acquired with FIB-tomography from porous Zr-oxide. The pore structures of the ceramic materials were investigated in context with optimization of transport properties (aimed for low viscous flow/permeability and high electric conduction via liquid electrolyte in the pores), so that the Zr-oxide is suitable for application as liquid junction (diaphragm) in pH-sensors. Further details on the scientific background are given in Holzer et al., 2016, Materials & Design, 99, 314–327. (http://doi.org/10.1016/j.matdes.2016.03.034).</p> <p> </p> <p>The tomographs represent 9 ceramic materials that were produced with different sintering temperatures (1250, 1300, 1325 and 1350°C) and different sintering times (1, 2 and 3 hours). The study includes quantitative descriptions of relevant microstructure characteristics (porosity, tortuosity, constrictivity, hydraulic radius) and corresponding effective transport prorperties (permeability, conductivity).</p> <p> </p> <p>Each tomograph is presented as stack of 2D-tiff-images in two different versions: as gray-scale images (raw data) and as binarized images (segmented, with solid=black and pores=white). The voxel resolution is 10x10x10 nm for all 18 image stacks.</p> <p> </p> <p>More details on the image data (e.g. voxel nr, image window size, data size) are given in the downloadable file '2_3D_Data_Info.xlsx'.</p>
Data from: The fabrication of the heterojunction catalyst BiVO4/P25 and its visible-light photocatalytic activities
A heterojunction catalyst BiVO4/P25 was successfully fabricated using a one-step hydrothermal method. The BiVO4/P25 samples exhibited better photocatalytic activities and absorption performances when compared with the pure BiVO4. The degradation rate of the methyl blue (MB) solution (5 mg/L) reached up to 85% in sixty minutes under visible-light illumination (λ > 420 nm). The nanocomposites were characterized using XPS, Raman spectroscopy, FT-IR, UV–visual diffuse reflectance spectroscopy, SEM and HR-TEM. A high-powered scanning electron microscope showed a polyhedron shape and a flower-like shape. The BiVO4/P25 nanocomposite was found to have a rougher surface, as well as a larger surface area, when compared with the pure BiVO4. This resulted in an improved photocatalytic activity, along with super absorption to a large extent.
Data from: Facile fabrication of Mn2+ doped ZnO photocatalysts by electrospinning
In this study, we report a high efficiency photocatalyst synthesized by Mn2+ doped ZnO nanofibers (NFs) fabricated by facile electrospinning and a following annealing process, in which Mn2+ successes incorporate to ZnO NFs lattice without changing any morphology and crystalline structure of ZnO. The photodegradation properties were studied for ZnO doping with different concentrations of Mn2+ (5, 10, 15 and 50 at.%). The 50 % Mn2+-doped ZnO NFs owns excellent active photocatalytic performance (quantum efficiency up to 7.57 %) compared to pure ZnO (0.16 %) under visible light and can be considered as an efficient visible-light photocatalyst material. We systematically analyzed the catalytic mechanism and showed that the enhancement belongs to the Mn doping effect and the phase junction between MnO and ZnO. The dominant mechanism of Mn doping leads to the presence of impurity levels in the band gap of ZnO, narrowing the optical band gap of ZnO. In addition, doped Mn2+ ions can be used as electron traps that inhibit the recombination process and promote electron-hole pair separation. Overall, this paper provides a facile approach to fabricate a highly efficient visible-light photocatalyst using controlled annealing.

Stim circuits for 'Accommodating Fabrication Defects on Floquet Codes with Minimal Hardware Requirements' manuscript
<p>Example Stim circuits for Honeycomb quantum memory experiments with defective qubits.</p> <p>Because accommodating each sample of fabrication defects requires a separate Stim circuit, we only provide example circuits rather than all Stim circuits used in simulations.</p> <p>Please note that the example circuits presented here are constructed by sampling defective qubits according to an iid distribution, with a single parameter defining the probability of an individual qubit being defective. In general a circuit which has a higher probability of each qubit being defective will perform worse than a circuit which has a lower probability of each qubit being defective. However, this does not necessarily mean that the specific circuits presented here will see that behaviour, as these are just individual samples from a large distribution.</p> <p>V2: Uploaded more example circuits with a higher target distance.</p>
All-Inkjet-Printed Humidity Sensors for the Detection of Relative Humidity in Air and Soil—Towards the Direct Fabrication on Plant Leaves
<p>We demonstrate the fabrication, by exclusive means of inkjet-printing, of capacitive relative humidity sensors on flexible, plastic substrate. These sensors can be successfully used for the measurement of relative-humidity in both air and common soil. We also show that the same technique may be used for the fabrication of the same type of sensors on the surface of the leaves of Elægnus Ebbingei (silverberry).Our results demonstrate the suitability of leaves as substrate for printed electronics and pave the way to the next generation of sensors to be used in fields such as agriculture and flower farming.</p>

Inverse magnetic fabrics caused by magnetofossils in the northwestern South China Sea since end of the Last Glacial
<p>The relationships among the abundance of magnetofossils, the ensuing magnetic properties, and the controlling paleoenvironmental factors in marine sediments remain broadly unexplored. Here, we identify magnetofossils in core XB1 from the northwestern South China Sea since the Last Glacial Maximum. Using rock magnetic and electron microscopic data, we propose a model that links the anisotropy of magnetic susceptibility fabric and the abundance of magnetofossils. The magnetofossil concentration in sediments increases significantly during the 14.7-4.7 ka period, which in turn leads to inverse magnetic fabrics and near-horizontal of minimum magnetic susceptibility axes. Further, we show that the abundance of magnetofossils is linked to paleoenvironmental changes in the northwestern South China Sea. The production and preservation of magnetofossils during the 14.7-4.7 ka period is promoted by an intensified East Asian summer monsoon and sluggish deep-water ventilation, while the paucity of magnetofossils after 4.7 ka is attributed to high oxygen content.</p>
Weaving the Penelope Fabric. Part III: Unweaving
<p>A famous vase from Chiusi depicts Penelope in front of a patterned fabric. The video demonstrates how such a fabric, once woven on a warp-weighted loom, could have been unwoven. Depictions of Penelope's unweaving the fabric ny night often show her tearing apart the fabric or its threads. This video demonstrates that it is not easy to distinguish weaving from unweaving, especially in an image or photograph. The video was taken in 2021 in the PENELOPE laboratory in the Museum for Plaster Casts of Classical Sculptures.</p>
