To investigate the synergetic effects of laser texturing and super-hydrophobic coatings on tribological performances , we prepare micro-grooves on steel substrates by femtosecond laser and then deposit super-hydrophobic coatings in the micro-grooves to obtain coated groove-textured surfaces (CGSs). The tribological behaviors of polished steel surfaces (PSSs), groove-textured surfaces (GSs), and CGSs under water lubrication are examined. Compared with PSSs and GSs, CGSs show significant anti-friction and wear-resisting properties under a relatively low load. With increasing the texture density, the wear resistance of CGSs decreases. When a load of 0.5 N is applied on the CGSs with a texture density of 10%, the friction coefficient and wear loss are reduced by 22.3% and 73.5%, respectively, compared with PSSs.

In this study, the influences of organic selenium (Se, 0.002 mg/L) on the muscle flavor and texture properties of Micropterus salmonides under fasting temporary rearing (8 weeks) was investigated. Electronic nose and headspace solid-phase microextraction-gas chromatography – mass spectrometry analysis suggested that organic Se regulated the types and contents of volatile compounds, especially aldehydes and ketones, which were increased in the early temporary rearing but decreased in the late stage. Organic Se significantly increased the content of 5′-inosine monophosphate by approximately 15 % ( p < 0.05), and decreased the content of hypoxanthine and hypoxanthine ribonucleoside by more than 20 % ( p < 0.05). After the 8th temporary rearing week, muscle hardness and springiness increased by at least 10 % ( p < 0.01), resilience and gumminess improved by at least 18 % ( p < 0.05) and 5.9 % ( p < 0.05), respectively. In conclusion, organic Se ameliorates the flesh quality of M. salmonides during long-term temporary rearing.

Crystallography regulation of a zinc (Zn) metal substrate to expose more (002) textures holds great promise for stabilizing Zn anodes. However, significant challenges remain in directly constructing a single (002)-plane-textured Zn metal anode (S-(002)-Zn) and realizing a sustainable (002)-texture exposure in working batteries. Herein, we report an anion and cation coregulated nonepitaxial electrodeposition to fabricate S-(002)-Zn by introducing 1-ethyl-3-methylimidazolium iodide (EmimI) additives in low-cost ZnSO4 aqueous electrolyte (ZS). Mechanistic studies reveal that the cooperation of Emim+ and I– with oriented adsorption behaviors on Zn can synergistically boost the (100) plane growth, depress the (002) plane growth, and suppress H2 evolution, thus enabling compact S-(002)-Zn electrodeposition. Moreover, other similar organic iodides (e.g., dimethyl-imidazolium iodide and 1-propyl-3-methylimidazolium iodide) are applicable to this scalable electrodeposition. On the other hand, the as-designed ZS-EmimI electrolyte can be directly applied in working Zn batteries, thus effectively sustaining the smooth (002) texture of S-(002)-Zn and inhibiting HER during cycling. Consequently, the combination of single-(002)-texture and ZS-EmimI electrolyte endows the S-(002)-Zn anode with an ultralong lifespan over 10,100 h (>14 months) at 1 mAh cm–2 and superior deep-cycling stability under 88.0% utilization (25 mAh cm–2) over 500 h and assures the stable operation of full Zn batteries.

The CO2 electrochemical reduction (CO2ER) to produce valuable multicarbon products represents a promising approach for enhancing CO2 conversion. While previous research has investigated the impact of Cu electrode surface topography on C2 production, it is important to note that other parameters were also altered concurrently with changes in roughness. To isolate the specific effect of surface texture on CO2 electroreduction, this study prepared Cu layers with varying textures using the sputtering method with a varied sputtering time. To characterize the surface features of the sputtered Cu layers, the developed interfacial area ratio (Sdr), known as areal parameter, was introduced, with the aim of correlating it with C2 product selectivity. The results of this study indicate that the improved selectivity of C2 products can be attributed to higher Sdr values, primarily due to a rougher and finer surface texture that increases the local concentration of CO and OH–. This research underscores the significance of surface topography and offers perspectives for designing efficient Cu electrodes for the CO2ER.

Aqueous zinc-ion batteries (AZIB) are significantly constrained by the poor stability of Zn anodes in aqueous electrolytes, which is caused by uncontrollable deposition behavior and parasitic reactions. The construction of specific crystalline surfaces represents an effective method for stabilizing Zn anodes. Therefore, a stable Malic acid@Zn (MA@Zn) anode with a highly (101) texture configuration is developed through acid etching. The mechanism of MA selective etching is investigated through theoretical calculations, where Zn atoms detach from the (002) crystal surface due to the strong interaction of MA with the (002) surface, leading to the preferential corrosion of the (002) surface and the formation of a unique (101) texture configuration morphology. This texture is conducive to the MA@Zn anode, as it enhances the affinity of MA@Zn for Zn 2+ and optimizes the electric field distribution on the surface, thereby facilitating a more stable Zn deposition. Consequently, the MA@Zn symmetric battery is subjected to stable cycling for a period exceeding 2400 h at a current density of 5 mA cm −2 . In comparison, the cycle life of the Zn//V 2 O 5 full battery is significantly improved by >6000 cycles, pouch battery also shows better performance.

Capturing both structural and pigmented iris textures is essential for accurate identity authentication and medical testing, particularly for heavily pigmented irises. Traditional near-infrared (NIR) lighting captures only structural details, while multiwavelength LEDs capture both but hinder device miniaturization. We present a solution using a phosphor-converted LED (pc-LED) that emits both visible and NIR light, combining commercial CaAlSiN3:Eu2+ and Ca3LuAlGe3O12:Cr3+ phosphors. This compact lighting source improves the emission efficiency and thermal stability through Lu3+ substitution with Al3+, allowing for the capture of clear iris images that reveal both structural and pigmented textures. Our results highlight the potential of visible and NIR pc-LEDs to enhance iris biometrics for portable devices and reduce the cost of iris medical testing equipment.

Adjusting the growth kinetics of the interfacial compound layers may be a feasible way to enhance joint properties or service performance. In this study, the textured Ti 3 SiC 2 was obtained by hot-deforming the sintered Ti 3 SiC 2 (TSC), and the effects of the texture orientation on the interfacial microstructural evolution and growth kinetics of the interfacial compounds in the diffusion bonded TiAl/Ti 3 SiC 2 joints were investigated. The texture orientation of Ti 3 SiC 2 had little effect on the interfacial microstructural evolution but had a significant effect on the growth kinetics. When bonded at the same temperature, the growth rate of the interfacial compound layers in the TiAl/TSC ∥ joint (TSC ∥ , TSC ⊥ : Ti 3 SiC 2 with [0001] texture orientation parallel, perpendicular to the bonded seam) was fastest; which was slowest in the TiAl/TSC ⊥ joint and was in the middle in the TiAl/TSC joint. The highest shear strengths of the three different joints were similar (about 54 MPa).

Inspired by the ability of tree frog toes to regulate body fluids, this control mechanism is applied to the tooth surface of slewing bearing (AISI 4140 steel (AS)) by adopting the regular hexagonal microtexture. SnAgCu-TiC (SACT) lubricants are filled in the microtextures. Results of two-factor analysis of variance show that there is a significant interaction between the microtexture and lubricants. When the microtextures with 1000 µm side are filled with SnAgCu-4 wt% nano-TiC (AS-SACT410), coefficient of friction (COF) of sample is the lowest. Compared with AS (0.437), COF of AS-SACT410 is reduced to 0.085, decreased by 80.55%. Macroscopic anti-friction originates because SnAgCu wraps around nano-TiC to form tribofilms containing submicron rollers, achieving substantially reduced COF.

Tuning substrate properties is an effective methodology to modulate the texture development of MgO films deposited by ion beam-assisted deposition (IBAD) process for epitaxial oxide films. Herein, a solution deposition planarization (SDP) technique is employed to deposit Gd-Zr-O layer for engineering surface properties of the flexible metal substrate. The correlation between the Gd-Zr-O thin film microstructure and the IBAD-MgO texture is investigated. The coordinated study on atomic force microscopy (AFM) and reflection high-energy electron diffraction (RHEED) reveal that the grain coarsening during high-temperature sintering negatively influences the texture formation of IBAD-MgO. Moreover, the chemical environment of the atoms on the surface of Gd-Zr-O seed layer also plays a critical role, which is normally overlooked. The X-ray photoelectron spectroscopy (XPS) analysis indicates that the carbon residue and intermediate phase result in the poor texture of the IBAD-MgO. This phenomenon is related to the partial decomposition and synthesis reactions due to the lower sintering temperature or reduced surface to volume ratio. We demonstrate the high-quality texture of IBAD-MgO layer, deposited on mono-coated thick Gd-Zr-O film, by using optimal heat-treatment conditions. The cross-sectional TEM images present the dense Gd-Zr-O film with Gd 2 Zr 2 O 7 nanograins. The multifunctionalities, such as planarization, a barrier layer, and seed layer, of Gd-Zr-O layers are realized in full-stacked CeO 2 /LaMnO 3 /IBAD-MgO/SDP-Gd-Zr-O/C276 samples. This work demonstrates a route for simplifying the architecture of 2G-HTS using Gd-Zr-O layer and explores the effect of the surface properties on texture formation in IBAD-MgO layer.

The grain preferential orientation has a significant influence on the mechanical properties of silicon nitride (Si 3 N 4 ) ceramics. Based on the Jeffery’s theory, a grain rotation model under uniaxial compression is created to predict the texture evolution mechanism during sintering of Si 3 N 4 ceramics. With deformation, the grain orientation was predicted to rotate towards the plane perpendicular to the pressure direction, and large strain was favorable for the formation of strong texture. According to guidance of the model, the weakly textured microstructure prepared by normal hot pressing is attributed to the limited strain, due to the constrains of graphite die. Therefore, a new PHIP (pseudo-hot isostatic pressing) process with the large deformation is guided to fabricate the strongly textured ceramics by promoting the grain rotation and dynamic grain growth. Generally, the experimental results are well accordance with the model prediction. Furthermore, this model could be applied to guide the design and fabrication of other isotropic and anisotropic ceramic materials.
