Summary: In this study, a gradient Zn anode (LLP@TreatedZn) with a passivated-layer at the top and fresh-zinc-layer at the bottom was developed using potassium permanganate solution treatment and laser lithography. The passivation layer prevents corrosion and side reactions, while promoting preferential deposition of Zn at the bottom of the microchannel. The LLP@Treated Zn anodes exhibited stable cycling performance over 700h at high current densities. Laser lithography also allowed for the fabrication of Zn anodes with different surface morphologies.

Summary: This article investigates the surface formation mechanism of single crystalline diamond (SCD) using nanosecond pulsed laser, involving surface cracking, phase transformation, and typical surface morphology. The study focuses on the nanometric surface characteristics of ablated micro-grooves on diamond caused by the thermal effect, crack generation and propagation, as well as the formation mechanism of induced and deposited metamorphic layers near the ablated groove. The results reveal the coexistence of distributed crystalline diamond and oriented graphite in the diamond/graphite transition layer, with a direction at an angle of 60°-80° to the laser scanning direction towards the center of the ablated groove.

Summary: The layered arrangement improves the oxidation resistance of TiN under the working conditions of steam power plants, as well as the mechanical properties of CrN. The produced architectures performance under the described working conditions boosts the understanding of the processes taking place at high temperature, making possible the design of optimal coatings combining the best behavior of both nitrides for each specific application, reaching a corrosion protection at high temperature in water vapor comparable to that of CrN and a hardness and Young's modulus as high as those of TiN.

Summary: Despite similar mechanical properties between snake skin and epoxy resin, strong differences in frictional and wear mechanisms were revealed. Snake skin exhibited a considerably lower and stable frictional coefficient over several sliding cycles. Reduction of stick-slip behavior and wear mechanism changes were observed by analyzing friction coefficient variation in forward and reverse motion.

Summary: This paper proposes a framework using machine learning to predict femtosecond laser-induced nanopatterns on Nickel. By integrating partial physical knowledge into the Swift-Hohenberg partial differential equation, the authors develop a method to learn with few data and without initial conditions. The results show good agreement with experimental data and reveal the relationship between pattern features, providing constraints for novel pattern design.

Summary: The formation of monoclinic VO2 crystal domains at low temperatures in nanocolumnar vanadium/oxygen thin films deposited via magnetron sputtering is analyzed. The synthesis involved depositing amorphous nanocolumnar VO1.9 thin films at room temperature and annealing them at temperatures between 250 - 330 ? in an oxygen atmosphere. The nanocolumnar structures exhibited a thermochromic transition at 47 ? (for annealing at 270 ?) and 58 ? (for annealing at 280 and 290 ?), resulting in a significant drop in optical transmittance in the infrared region.

Summary: Ultrafast laser irradiation can induce spontaneous self-organization of surfaces into dissipative structures with nanoscale reliefs. These surface patterns emerge from symmetry-breaking dynamical processes that occur in Rayleigh-Benard-like instabilities. This study demonstrates the numerical unraveling of the coexistence and competition between surface patterns of different symmetries using the stochastic generalized Swift-Hohenberg model. A deep convolutional network is proposed to identify and learn the dominant modes that stabilize for a given bifurcation and quadratic model coefficients. The approach enables the identification of experimental irradiation conditions for a desired self-organization pattern and can be generally applied to predict structure formation in situations where the underlying physics can be approximately described by a self-organization process and data is sparse and nontime series.

Summary: Vanadium dioxide (VO2) exhibits a reversible insulator-to-metal transition and structural phase transition from monoclinic M1 to rutile tetragonal R. Selective deposition of VO2 thin films with different phases is challenging due to their narrow thermodynamic stability. This study successfully synthesized VO2 thin films with M1, T, and M2 phases using pulsed laser deposition and demonstrated the dependence of properties on the phases and laser repetition rate. Stabilizing different polymorphs of VO2 thin films opens up possibilities for novel device functionalities.
