Abstract: Flexible perovskite solar cells (FPSCs) hold great promise for lightweight and wearable photovoltaics, but improving their efficiency and durability under mechanical stress remains a key challenge. In this work, we fabricate and characterize flexible planar FPSCs on a polyethylene terephthalate (PET). A phenethylammonium iodide (PEAI) surface passivation layer is introduced on the perovskite to form a two-dimensional capping layer, and its impact on device performance and stability is systematic[...]
Our summary: Enhanced efficiency and mechanical stability achieved in flexible perovskite solar cells through PEAI surface passivation, leading to improved device performance and durability under mechanical stress. Integration of PEAI treatment with optimized ETL and HTL layers enhances efficiency and flexibility, paving the way for reliable and high-performance wearable solar cells.

Methods for wet atomic layer etching of molybdenum
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[...]
Our summary: Methods for wet atomic layer etching of molybdenum using various oxidation techniques to form a self-limiting passivation layer for selective removal in a dissolution step.

Effect of T6 Tempering on the Wear and Corrosive Properties of Graphene and B4C Reinforced Al6061 Matrix Composites
Published on 2025-03-05 by Bharathiraja Parasuraman, Anthony Xavior Michael @MDPI
Abstract: This research study aims to evaluate the wear and corrosive behaviour of aluminum 6061 alloy hybrid metal matrix composites after reinforcing them with graphene (0.5, 1 wt.%) and boron carbide (6 wt.%) at varying weight percentages. The hybrid composites were processed through ball milling and powder compaction, followed by a microwave sintering process, and T6 temper heat treatment was carried out to improve the properties. The properties were evaluated and analyzed using FE-SEM, Pin-on-Disc tr[...]
Our summary: This study evaluates the effect of T6 tempering on the wear and corrosive properties of Al6061 matrix composites reinforced with graphene and B4C. The composites were processed and tested before and after the heat treatment, showing improvements in wear resistance and corrosion rate reduction. Increasing graphene content negatively impacted the properties of the hybrid composites.
