Laser Powder Bed Fusion (LPBF) is a leading Additive Manufacturing (AM) technique for creating metallic alloys. However, its rapid heating and cooling rates can lead to residual stresses, defects, and undesirable microstructures. The main goal in LPBF is t ...

The properties of clusters of colloidal particles, often termed supraparticles, are determined by the arrangement of the primary particles. Therefore, controlling the structure formation process is of key importance. While buckled morphologies can result f ...

The discovery of self-assembled molecular layers (SAMLs) containing anchoring groups such as COOH and PO3H as efficient hole-selective materials (HSMs) in p-i-n perovskite solar cells (PSCs) is pivotal to enhancing the interaction between HSMs and perovski ...

The growth kinetics of vertical III−V nanowires (NWs) were clarified long ago. The increasing aspect ratio of NWs results in an increase in the surface area, which, in turn, enhances the material collection. The group III adatom diffusion from the NW sidew ...

Artificial photosynthesis is considered to be a promising approach for energy storage and global warming mitigation. However, the suboptimal selectivity of products and the low conversion efficiency of CO2 persist as challenges, driving continuous interest ...

Laser beam shadowing in directed energy deposition process occurs when in-flight powder particles partially block the laser beam, preventing it from fully reaching the melt pool. This blockage alters the beam's profile, introducing spatio-temporal randomne ...

Porous single -layer graphene is promising as the selective layer for membrane-based gas separation thanks to the atomic thickness of the pore which can yield high permselective flux. Direct synthesis of porous graphene by chemical vapor deposition (CVD) i ...

Organic semiconductors (OSCs) have emerged as promising active layers for photoanodes to drive photoelectrochemical (PEC) oxidation reactions. Interfacing an OSC with an inorganic electron transport layer (ETL) is key to enabling both high performance and ...

Strain is an inevitable phenomenon in two-dimensional (2D) material, regardless of whether the film is suspended or supported. Moreover, strain is known to alter the physical and chemical properties, such as the band gap, charge carrier effective masses, d ...

Hexakis(hexyloxy)triphenylene (HAT6) discotic liquid crystal is employed as a transparent hole-transporting material (HTM) for perovskite solar cells (PSCs) and a power conversion efficiency (PCE) of 15.7% is obtained, which is the highest using HAT6 type ...

The structural properties of octahedral sites (B-Oh) in spinel oxides (AB(2)O(4)) play vital roles in the electrochemical performance of oxygen-related reactions. However, the precise manipulation of AB(2)O(4) remains challenging due to the complexity of t ...

Nanopores in two-dimensional (2D) membranes hold immense potential in single-molecule sensing, osmotic power generation, and information storage. Recent advances in 2D nanopores, especially on single-layer MoS2, focus on the scalable growth and manufacturi ...

The development of generation IV nuclear reactor requires improvements in structural and cladding materials. Oxide dispersion strengthened (ODS) steels are promising candidates because of improved creep properties. Two main families of ODS steels are known ...

Amphiphilic gold core nanoparticles (AmNPs) striped with hydrophilic 11-mercapto-1-undecanesulfonate (MUS) and hydrophobic 1-octanethiol (OT) ligands are promising candidates for drug carriers that passively and nondisruptively enter cells. Yet, how they i ...
