Silver‐enhanced Photoresponsive g‐C3N4/Ag Janus Microrobots With Negative Photogravitaxis Efficient Antibiotic Degradation

open access: yesSmall, EarlyView.
ABSTRACT Water pollution remains a serious global challenge; hence, the efficient, low‐cost, and environmentally friendly removal of pollutants from water has become a research hotspot. Photocatalytic microrobots can achieve autonomous movement and generate reactive oxygen species (ROS), presenting a great opportunity for water purification.

Laying the Foundation for Digital Material Design of Porous Transport Electrodes for PEM Water Electrolysis With Multiscale Tomography

open access: yesSmall, EarlyView.
This paper presents the first multiscale identical location tomography of a porous transport electrode for PEM water electrolysis. Different tomography and modeling approaches determine the relevant structural properties ranging from micrometer‐thick fibers to nanometer‐thin binder films covering the catalyst particles.

Vacancy‐Induced Z‐Contrast Anomaly in Self‐Assembled (Ti,V)O2 Heterostructure

open access: yesSmall, EarlyView.
This study investigates the unexpectedly high contrast observed in ADF‐STEM imaging of spinodal decomposed (Ti,V)O2 heterostructure. In situ heating, GPA, and EELS analyses reveal that oxygen vacancies accumulate in V‐rich layers due to facilitated vacancy migration along [001]R pathways during phase separation by spontaneous ionic diffusion.

Essential Role of Icosahedral Symmetry in the 3D Shape of AuAg Plasmonic Nanostars With High Aspect‐Ratio Legs

open access: yesSmall, EarlyView.
Electron nanodiffraction mapping was used to determine that the 3D leg configuration of branched plasmonic AuAg nanostars is associated with the icosahedral symmetry of the star core, providing a deeper understanding of their growth mechanism and thus paving the way to the development of optimized synthesis protocols targeting optical enhancement ...

Optimal Placement of Grid Battery Energy Storage Systems for Congestion Mitigation and Enhanced Power‐Flow Control Considering Uncertainties in Photovoltaic Deployment

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Amidst the global drive toward carbon neutrality, the integration of large‐scale photovoltaic (PV) systems introduces significant challenges related to grid congestion. Battery energy storage systems (BESSs) are increasingly recognized as an effective solution for addressing these challenges and improving grid operations, especially under the ...
