title: Operando PDF and XAS to study effect of different electrolytes on intermediate phases of Sn-based anodes in Na-ion batteries

description: Conversion-alloying materials (CAMs) as anode materials for Na-ion batteries (NIBs) are capable of 
delivering a stable capacity higher than that of state-of-the-art materials. However, CAMs have a very 
complex cycling mechanism as they undergo a series of transformations with formation of crystalline 
and/or amorphous phases. [1,2] We have recently discovered a strong dependency of cycling 
mechanisms in batteries on the selected electrolyte. [3] However, the current understanding of effect 
of different electrolytes on de(sodiation) mechanism of CAMs is very limited. The proposed
experiment will elucidate the operating mechanism of sub stoichiometric Tin (II) oxides (SnOx) in
different electrolytes for NIBs using combined pair distribution function (PDF) and X-ray absorption 
spectroscopy (XAS). This experiment aims to highlight fundamental differences in cycling and 
performance caused by electrolytes on SnOx.

title: Independent Experimental Confirmation of Force-Line Photon Topology by the 2025 Supersolid Light Experiment – Robert J. Weber – November 21, 2025

description: The 2025 supersolid-light experiment (CNR Nanotec / University of Pavia, published in Nature) that created a supersolid state of light in a semiconductor lattice was performed without knowledge of the force-line photon model (DOI 10.5281/zenodo.17667143). The observed freezing of photons into a rigid crystalline pattern while retaining superfluidity is precisely the mechanical locking of open force-line pairs when their latent electron/positron halves fall into phase-coherent topological wells. This constitutes an independent experimental confirmation of the pure-particle, topological nature of light and the elimination of wave-particle duality.

The same topological mechanism that gives photons transient mass in the lattice produces the permanent gluon mass in pure Yang–Mills theory via line kinking (DOI 10.5281/zenodo.17619003).

title: A Labeled Shearography Dataset for Kissing Bond Anomaly Detection in Polymer–Rubber Adhesive Layers

description: This dataset contains shearographic measurement data of simulated kissing bonds in a polymer–rubber adhesive joint. The defects were created by inserting defined discontinuities within the adhesive layer, producing fully detached bonding regions. In addition, the dataset includes reference measurements without defects, which contain only global deformation used to generate the phase jumps. 

The dataset consists of three classes of samples:



Defective samples with simulated kissing-bond anomalies (Faulty)

Non-defective samples without any adhesive discontinuities and without global Deformation (Good_clean)

Non-defective samples without any adhesive discontinuities and with global deformation (Good_stripes)


Ground-truth annotations (Bounding Box, CSV and YOLO Format) are provided only for the defective regions in the defective samples (Faulty). The background and all non-defective areas remain unlabeled. The labels were manually created by a domain expert. This results in partially labeled data that may be used in supervised, weakly supervised, or unsupervised analysis methods.

title: Dataset of "Photoelectrochemical generation of H2O2 using hematite (α-Fe2O3) and gas diffusion electrode (GDE)"

description: In contrast to the industrial-scale production of H2O2 the electrochemical or photoelectrochemical synthesis is environmentally friendly. In the present work, the photoelectrochemical generation of H2O2 was studied by combining the hematite (α-Fe2O3/FTO/glass) photoanode and gas diffusion electrode (GDE) modified by incorporation of tin (II) phthalocyanine (SnPc) in its hydrophilic layer. The experiments were carried out in a photoelectrochemical cell with two compartments separated by a proton exchange membrane under applied bias and AM1.5 irradiation (100 mW/cm2). The generated amount of H2O2 was determined by chemical analysis (visible light spectrophotometry) of the electrolyte. As a tool to determine the efficiency of such a process, the Faradaic efficiency (FE) was calculated. The best configuration used air as an inlet gas for GDE and phosphate buffer (pH 6.4) as an electrolyte in the cathodic compartment. The combination of hematite and GDE (with SnPc) was the most effective in H2O2 photoelectrochemical generation. The highest value of FE was 52.4 % for GDE (O2 reduction to H2O2) and 0.4 % for hematite photoanode (H2O oxidation to H2O2).
