Summary: This paper presents the design of an effective pulse current deposition process for low stress, crack-free Cr coatings deposited from standard Cr3+ electrolyte commonly used by industry. The parameters for the pulse current deposition process are determined based on detailed analysis and modeling of in situ stress transients during Cr deposition and relaxation. A general procedure and criterion are derived for pulse current function design, which has broader significance for the synthesis of functional Cr coatings. Comparative characterization of pulse and direct current deposited Cr films is provided, demonstrating superior properties and stress-state of the Cr films deposited using the newly developed approach to pulse current function design.

Summary: Co-Cr and Co-Cr/ZrO2 coatings were electrodeposited from Cr (III) based baths. The incorporation of ZrO2 nanoparticles decreased the density of micro-cracks within the coatings, and immediate heat treatment prevented the formation of micro-cracks and significantly decreased their amount. The composite coatings had higher hardness and corrosion resistance compared to the unreinforced Co-Cr coating, with the optimum sample Co-Cr/5 g L-1 ZrO2 showing 1.2 and 7 times higher hardness and corrosion resistance, respectively, than the unreinforced electrodeposit. Heat treatment further increased the hardness and polarization resistance of the Co-Cr/5 g L-1 ZrO2 coating by 1.5 and 3 times.

Summary: Ni-P/TiC nanocomposite coatings were developed on HSLA substrates through pulse electrodeposition, with different concentrations of TiC nanoparticles. The coatings exhibited improved structural, compositional, mechanical, wear, and electrochemical properties, with Ni-P/0.75TiC composition showing the highest mechanical response and lowest wear rate. The corrosion resistance of Ni-P coatings was substantially increased by incorporating TCNPs, with Ni-P/0.75TiC coatings demonstrating the highest corrosion protection efficiency of 94% in saline water due to the compact structure containing inactive TCNPs in the Ni-P matrix.

Summary: The research discovered that applying pulse electrodeposition with a triangular waveform to Ni-Cu alloy coatings resulted in the best corrosion resistance, while using a ramp waveform led to the lowest surface roughness and grain size. Additionally, the corrosion resistance of the Ni-Cu alloy coatings was found to depend significantly on the molar fraction of Cu in solid solution and the crystallographic orientation, with the highest corrosion resistance associated with the largest molar fraction of Cu in solid solution and growth of grains at (111) orientation.

Summary: Smooth and dense nanocrystalline Cr coatings with solid solution Al were successfully electrodeposited using the proposed Cr2+ electrolyte without any additives, AlCl3-1-ethyl-3-methyl-imidazolium chloride (AlCl3-EMIC) ionic liquid dissolving CrCl2. The presence of Al in the coating was confirmed by various analyses, and its deposition on Cr deposits was attributed to the underpotential deposition (UPD) of Al. The resulting coatings exhibited excellent properties, such as high hardness and low corrosion current density.

Summary: The terrestrial water cycle is influenced by processes such as precipitation, evaporation, runoff, and atmospheric moisture convergence. Understanding how vegetation cover affects the water cycle is challenging, but recent studies have shown that changes in plant transpiration can have a disproportionate impact on rainfall. It has been found that in a sufficiently wet atmosphere, increased transpiration can enhance atmospheric moisture import and water yield, while in a dry atmosphere, increased transpiration reduces moisture convergence and water yield. Evaluating these relationships is crucial for understanding the consequences of deforestation and guiding ecological restoration efforts.

Summary: In this paper, a system dynamics model is used to analyze the production cycle of a nonrenewable natural resource, specifically crude oil. While this subject has been extensively studied empirically, there have been very few modeling studies that correlate the peaking with system parameters, and these have only been recently proposed. The paper examines the timing of the peaking primarily as a function of energy return on energy invested (EROI). The model provides approximate formulas for evaluating peak time and useful rules of thumb for understanding the peaking phenomenon in natural resource exploitation. It shows that the peaking of the production curve occurs at a time inversely proportional to the EROI of the process at the start of the cycle.

However, current metal-free tanning technologies have limitations in terms of water sorption and charge properties. By using cationic amphiphilic acrylic copolymers (PSD) as retanning agents, the properties of metal-free leather can be significantly improved, including enhanced hydrophobicity, better dye absorption, and excellent filling effect.

Summary: Four novel bis-chalcone-based carbazole derivative photoinitiators were designed and synthesized in this study. Their maximum absorption wavelengths were determined and found to exhibit high molar extinction coefficients. Furthermore, a three-component photoinitiation system including bis-chalcone/iodonium/amine was successfully used to trigger the rapid and efficient photopolymerization of acrylates. The photoinitiators also showed good photo bleaching and biocompatibility, making them suitable for applications such as 3D printing and deep coating curing.
