title: Evento Cero TCDS — Índice t_C Regional del Sismo M7.1 Puebla–Morelos (2017): Implementación Operacional en Termux–Android

description: Este dataset contiene la implementación completa y reproducible del Evento Cero TCDS aplicada al sismo M7.1 Puebla–Morelos del 19/09/2017. Utilizando el paradigma Q–Σ–φ de la Teoría Cromodinámica Sincrónica (TCDS), el método palíndromo y el filtro entrópico E-Veto, se genera un perfil completo del índice t_C regional a partir de métricas agregadas (LI_mean, R_mean, ΔH_mean) en ventanas A1, A2, B, C y D.

 

La ejecución se realizó en un entorno Termux–Android (Samsung S23), empleando un motor Σ reducido sin dependencias científicas pesadas. Los resultados muestran una elevación significativa de coherencia (LI=0.88, R=0.92), caída de entropía (ΔH=−0.22) y un aumento del índice causal (t_C≈1.03) en la ventana Pre (−24 h a t₀), consistente con un estado de tensión causal previa al evento.

 

El paquete incluye manifest JSON, motor de cómputo, salida final t_C y documentación para reproducción. Este material constituye el primer caso operacional del marco predictivo TCDS, demostrando portabilidad, falsabilidad y reproducibilidad.

title: Band structures of passive films on titanium in simulated bioliquids determined by photoelectrochemical response: principle governing the biocompatibility

description: The band structures and band gap energies, <i>E</i><sub>g</sub>, of passive films formed on titanium (Ti) in simulated bioliquids, Hanks’ solution (Hanks) and saline, were evaluated. Ti was polarized at 0, −0.1, and −0.2 V<sub>Ag/AgCl</sub>, <i>E</i><sub>f</sub>, for 1 h. After polarization, the surfaces were characterized using X-ray photoelectron spectroscopy, and the photoelectrochemical responses were evaluated. The current change during photoirradiation was recorded as a photocurrent transient at each measuring potential, <i>E</i><sub>m</sub>, and by changing the wavelength of the incident light. Passive films consisted of a very thin TiO<sub>2</sub> layer containing small amounts of Ti<sub>2</sub>O<sub>3</sub> and TiO, hydroxyl groups, and water. During polarization in Hanks, calcium and phosphate ions were incorporated or formed calcium phosphate but not in saline. Calcium phosphate and hydroxyl groups influenced the band structure. <i>E</i><sub>g</sub> was graded in Hanks but constant in saline, independent of <i>E</i><sub>f</sub> and <i>E</i><sub>m</sub>. The passive film on Ti behaved as an <i>n</i>-type semiconductor containing two layers: an inner oxide layer with a large <i>E</i><sub>g</sub> and an outer hydroxide layer with a small <i>E</i><sub>g</sub>. In Hanks, <i>E</i><sub>g</sub> was 3.3–3.4 eV in the inner oxide layer and 2.9 eV in the outer hydroxide layer. In saline, <i>E</i><sub>g</sub> was 3.3 eV in the inner layer and 2.7 eV in the outer layer. Calcium phosphate and hydroxyl groups influenced the band structure of the passive film. The <i>E</i><sub>g</sub> of the outermost surface was smaller than that of TiO<sub>2</sub> ceramics, which is probably one of the principles of the excellent biocompatibility of Ti among metals.

title: Impact of spontaneous liposome modification with phospholipid polymer-lipid conjugates on protein interactions

description: Liposome surface coating has been studied to avoid the immunological responses caused by the complement system, and alternative materials to poly(ethylene glycol) (PEG) have been explored recently since the production of anti-PEG IgM antibodies has been found in humans. We previously reported a liposome coating with poly(2-methacryloyloxyethyl phosphorylcholine) (poly(MPC))-conjugated lipids (PMPC-lipids) and demonstrated its protective effect on blood protein interactions. Here, we attempted to modify the liposome surface by exogenously adding PMPC-lipids, which were spontaneously incorporated into the outer membrane via hydrophobic interactions. The polymerization degree of the PMPC segment was regulated from 10 to 100. The incorporated ratio of PMPC-lipid increased with a decrease in the degree of PMPC polymerization. Due to surface modification with PMPC-lipids, increase in the length of the PMPC-chain increased the size of the liposomes. The modified liposomes were kept stable for 14 d in terms of their size, polydispersity, and surface properties, where approximately 70% of PMPC-lipids were incorporated into the liposome surface. We demonstrated that liposome surface modification with PMPC-lipids can inhibit protein adsorption when exposed to serum, regardless of the degree of polymerization of PMPC. In addition, the PMPC-lipid modified surface was not recognized by the anti-PEG IgM antibody, whereas PEG-lipid was recognized by the antibody. Thus, we successfully fabricated an inert liposome surface via spontaneous modification with PMPC-lipids, where only the outer bilayer surface was modified. This technique can be available for full loading of water-soluble active pharmaceutical ingredient inside the modified liposome.

title: Superhydrophobic SLA 3D printed materials modified with nanoparticles biomimicking the hierarchical structure of a rice leaf

description: The rice leaf, combining the surface properties of lotus leaves and shark skin, presents outstanding superhydrophobic properties motivating its biomimesis. We created a novel biomimetic rice-leaf superhydrophobic surface by a three-level hierarchical structure, using for a first time stereolithographic (SLA) 3D printed channels (100µm width) with an intrinsic roughness from the printing filaments (10µm), and coated with TiO<sub>2</sub> nanoparticles (22 and 100nm). This structure presents a maximum advancing contact angle of 165° characterized by lower both anisotropy and hysteresis contact angles than other 3D printed surfaces, due to the presence of air pockets at the surface/water interface (Cassie-Baxter state). Dynamic water-drop tests show that the biomimetic surface presents self-cleaning, which is reduced under UV-A irradiation. The biomimetic surface further renders an increased floatability to 3D printed objects meaning a drag-reduction due to reduced water/solid contact area. Numerical simulations of a channel with a biomimetic wall confirm that the presence of air is essential to understand our results since it increases the average velocity and decreases the friction factor due to the presence of a wall-slip velocity. Our findings show that SLA 3D printing is an appropriate approach to develop biomimetic superhydrophobic surfaces for future applications in anti-fouling and drag-reduction devices.

title: A solvent-compatible filter-transfer method of semi-transparent carbon-nanotube electrodes stacked with silver nanowires

description: Low-density films of single-walled carbon nanotubes (SWNTs) can be used as a semi-transparent top electrode for all-solution-processed film devices; however, their semiconductor characteristics vary depending on the experimental factors in their dispersion into solvents, and the sublayers are damaged as a result of solvent incompatibility. In this study, we report a solvent-compatible filter-transfer method for SWNT films stacked with silver nanowires (AgNWs), and evaluate the semiconductor characteristics through the p/n heterojunction with a Si wafer (SWNT/Si). AgNWs and SWNTs were successively filtered through their aqueous dispersion solutions using a membrane filter. The stacked semi-transparent films (AgNW/SWNT films with controlled densities) were successfully transferred onto glass plates and Si wafers. The transmittance at 550 nm revealed a window between 60% and 80% with a narrow sheet resistance range between 11 and 23 Ω □<sup>−1</sup>. The power conversion efficiency (PCE) of SWNT/Si was improved to 11.2% in a junction area of 0.031 cm<sup>2</sup> through the use of spin-coated Nafion resins; however, the accumulated resistance of SWNTs drastically reduced the PCE to 2% as the area increased to ≥0.5 cm<sup>2</sup>. AgNWs maintained the PCE within a range of 10.7% to 8.6% for an area ranging from 0.031 cm<sup>2</sup> to 1.13 cm<sup>2</sup>. All of the photovoltaic parameters were dependent on the junction areas, suggesting that AgNWs function as an effective current-collector layer on the semiconductor layer of SWNTs without direct contact of AgNWs with the Si surface. In addition, we report a solvent-compatible experiment for transferring AgNW/SWNT films onto a solvent-sensitive perovskite material (CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>).

title: Lightweight mobile stick-type water-based triboelectric nanogenerator with amplified current for portable safety devices

description: Due to its abundance, mechanical energy is a promising ambient energy source. Triboelectric nanogenerators (TENGs) represent an effective mechanical energy harvesting method based on the use of contact electrification. The existing liquid-based TENGs can operate robustly without surface damage; however, the output of these TENGs is considerably smaller than that of solid-based TENGs. Notably, liquid-based TENGs in which the liquid directly contacts the conductive material can produce an electrical current of more than few mA. However, the liquid reservoir must have an adequate volume, and sufficient space must be provided for the liquid to move for generating the electrical output. To ensure a compact and lightweight design and produce electrical output in the low input frequency range, we introduce a mobile stick-type water-based TENG (MSW-TENG). The proposed MSW-TENG can generate an open-circuit voltage and closed-circuit current of up to 710 V and 2.9 mA, respectively, and be utilized as self-powered safety device. The findings of this study can promote the implementation of TENGs in everyday applications.
