Measuring agglomeration of agglomerated particles pictures

open access: yesMeasuring agglomeration of agglomerated particles pictures
In this article, we introduce a novel geometrical index δ_, which is associated with the Euler number and is obtained by an image processing procedure for a given digital picture of aggregated particles such that δ_ exhibits the degree of the agglomerations of the particles. In the previous work (Matsutani, Shimosako, Wang, Appl. Math.

Facet‐Selective Electrostatic Assembling of 2D Mxene onto Anisotropic Single‐Crystal Metal Oxides for Enhanced Photocatalysis

open access: yesAdvanced Materials, EarlyView.
Overcoming random aggregation, Facet‐Selective Electrostatic Assembly (FSEA) achieves site‐specific integration of 2D MXenes onto 3D TiO2 supports. This electrostatic assembling creates optimized interface energy junctions that facilitate spatial charge transfer.

Maximize the Electrocatalytic Activity of Pt Toward Ethanol Oxidation via Engineering PdPt1 Single‐Atom Alloy Skin

open access: yesAdvanced Materials, EarlyView.
Maximizing atomic utilization of Pt is crucial for efficient electrocatalysis. We constructed a tensile‐strained PdPt1 single‐atom alloy (SAA) skin by implanting atomically dispersed Pt onto the surface of intermetallic Pd5Bi3 core‐ultrathin Pd shell octahedrons, fully exposing active Pt atoms to boost ethanol oxidation electrocatalysis.

Scalable and Multifunctional PAN‐MXene Composite Fibers for Thermal Management, Photothermal Conversion, Energy Harvesting, and Sensing for Wearable Applications

open access: yesAdvanced Materials, EarlyView.
Electrospun PAN‐MXene nanofibers and yarns integrate enhanced thermal conductivity, photothermal conversion, and triboelectric energy harvesting within a flexible architecture. Interconnected MXene networks promote efficient phonon transport, while their surface chemistry strengthens tribo‐negative behavior, enabling a high power density of 432.7 mW m ...

On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions

open access: yesAdvanced Materials, EarlyView.
We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.
