YTaO4/Y₂Zr₂O₇ Dual-Phase Ceramics with Enhanced Vickers Hardness, Fracture Toughness and High Thermal Expansion Properties for Thermal Barrier Coating Applications
Published on 2025-03-11 by Ziyang Ruan, Zifan Zhao, Jing Feng @MDPI
Abstract: Rare-earth tantalates (RETaO4) are considered as a type of emerging thermal barrier coating materials applied to the hot components of gas turbines and aerospace engines due to their excellent thermal stability, high-temperature fracture toughness, corrosion resistance and extremely low thermal conductivity. However, the relatively low hardness and thermal expansion coefficients may limit their service lifetime in a harsh engine environment. To address the current limitation of rare-earth tantal[...]
Our summary: Rare-earth tantalates (RETaO4) are excellent thermal barrier coating materials for gas turbines and aerospace engines. Introducing YTaO4/YZrO7 dual-phase ceramics significantly enhances mechanical and thermal properties, making them ideal for thermal barrier coating applications.

Performance Assessment of Graphene Oxide as a Protective Coating for Historical Stone
Published on 2025-03-11 by Codrut Costinas, Liviu Cosmin Cotet, Lucian Baia, Naida El Habra, Luca Nodari, Patrizia Tomasin @MDPI
Abstract: Stone cultural heritage faces significant deterioration from environmental factors, necessitating protective treatments that preserve both functionality and appearance. In this study, graphene oxide (GO) was evaluated as a protective coating for both natural and artificially aged Euganean trachyte and Vicenza stone samples. GO was applied as a low-concentration aqueous dispersion (0.5 mg/mL) by brush, and samples were subsequently exposed to UV light for 7 h to simulate weathering. Performance w[...]
Our summary: Evaluation of graphene oxide as a protective coating for historical stone samples shows promising results in reducing water absorption and maintaining vapor permeability. UV exposure darkens the coating but enhances hydrophobicity, indicating potential for stone protection. Further research is needed to optimize coating uniformity and assess long-term durability.

Effect of Partial Fibre Laser Processing on the Wear Resistance of NiCrMoFeCSiB Coatings
Published on 2025-03-11 by Olegas ?erna�?jus, Jelena �kamat, ?ukasz Gierz, Olga Zharkevich, Alexandra Berg @MDPI
Abstract: Surface laser processing of metallic materials is known to be effective in improving wear resistance due to microstructure refinement and the associated hardening effect. However, the formation of cracks, which frequently accompanies such processing, remains a challenge. This work focusses on partial laser processing of Ni-based protective coatings as a method that could potentially reduce the risk of crack formation due to lower overall heat input and retaining softer material portions that fac[...]
Our summary: Effect of Partial Fibre Laser Processing on Wear Resistance of NiCrMoFeCSiB Coatings. Laser processing of Ni-based coatings improves wear resistance by refining microstructure and hardening material. Partial laser treatment reduces crack formation risk and enhances wear resistance significantly.

Evaluation of Thermal Stability and Thermal Transitions of Hydroxyl-Terminated Polysiloxane/Montmorillonite Nanocomposites
Published on 2025-03-10 by Sozon P. Vasilakos, Petroula A. Tarantili @MDPI
Abstract: Condensation-type polysiloxane composites with montmorillonite (MMT) of different organic modifications were prepared in this study. X-ray diffraction (XRD) characterization revealed that the higher degree of organic modification in Cloisite 20A, compared to that in Cloisite 30B, resulted in a larger interlayer spacing between the clay platelets. This facilitates the insertion of elastomer chains between the layers, enabling easier exfoliation and dispersion in the elastomeric matrix. Differenti[...]
Our summary: Evaluation of thermal stability and transitions of hydroxyl-terminated polysiloxane/montmorillonite nanocomposites. Higher organic modification in Cloisite 20A facilitates easier exfoliation and dispersion in elastomeric matrix. Incorporating organically modified clays significantly improves thermal stability of nanocomposites.

Effect of Surface Finish on CO2 Corrosion of Low-Alloy Steel in Simulated Sea Water and Well Environments
Published on 2025-03-10 by Kapil Kumar Gupta, Sarah Pedroni, Alexia Mercier, Saber Haratian, Oleg V. Mishin, Rajan Ambat @MDPI
Abstract: The study investigates the influence of surface finish on corrosion of a grade API L80 low-alloy steel. Samples of this steel with different surface finishes produced by rough mechanical grinding (RG sample) or by finer polishing (FP sample) have been studied after exposure to corrosive environments. It is found that the dissolution rate is one to two orders of magnitude higher for the RG sample with a rougher surface than for the FP samples with a smoother surface. Scanning electrochemical micr[...]
Our summary: Influence of surface finish on CO2 corrosion of low-alloy steel in simulated sea water and well environments. Study compares rough mechanical grinding (RG sample) and finer polishing (FP sample) surfaces. RG sample shows higher dissolution rate and selective corrosion, while FP sample exhibits slow uniform corrosion and localized corrosion over time.

Patent published on the 2025-03-06 in WO under Ref WO2025048957 by TOKYO ELECTRON U S HOLDINGS INC [US] (Dahal Tulashi [us], Abel Kate [us], Debasu Mengistie [us])
Abstract: Systems and methods are provided for etching molybdenum in a wet ALE process. The methods disclosed herein use a wide variety of techniques and wet etch chemistries to oxidize a molybdenum surface and form a self-limiting, molybdenum oxide passivation layer in a surface modification step of the wet ALE process. For example, the methods use: (a) ultra-violet (UV) photolysis of peroxide oxidizers to create oxidizing radicals, which limit oxidation of the molybdenum surface and provide quasi-self-l[...]
