Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Reactivity and Catalytic Activity of Hydrogen Atom Chemisorbed Silver Clusters

, 2015
Metal clusters of silver have attracted recent interest of researchers as a result of their potential in different catalytic applications and low cost. However, due to the completely filled d orbital and very high first ionization potential of the silver

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Bimetallic silver-gold clusters by matrix-assisted laser desorption/ionization

, 2004
Pure gold clusters (Aun+) were produced up to the cluster size of n = 100 by matrix-assisted laser desorption/ionization (MALDI). The mass spectrum of the resulting clusters showed alteration in the ion intensity at odd-even clusters size.

Quantum-sized silver, silver chloride and silver sulfide clusters

, 2001
Thin AgCl layers photocatalytically oxidize water to O2 under appropriate conditions. The photoactivity of AgCl extends from the UV into the visible light region in a process known as self-sensitization, which is due to the formation of silver during the

CERIUM IONS INFLUENCE ON A LUMINESCENCE AND ABSORPTION OF MOLECULAR SILVER CLUSTERS IN SILICATE GLASSES AFTER ION EXCHANGE [PDF]

Научно-технический вестник информационных технологий, механики и оптики, 2013
Luminescence and absorption spectrums of silicate glasses containing silver, embedded by ion exchange, were investigated. Intensive luminescence of such glasses was shown to appear right after ion exchange that can be associated with neutral molecular ...

Trapping an octahedral Ag6 kernel in a seven-fold symmetric Ag56 nanowheel

Nature Communications, 2018
High-nuclearity silver clusters are appealing synthetic targets for their remarkable structures, but most are isolated serendipitously. Here, the authors describe the rational use of solvents to form cluster-in-cluster silver nanowheels, which comprise ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Photostimulated luminescence of silver clusters in zeolite-Y

, 1997
Upon UV-irradiation at 254 nm, the photoluminescence of silver atoms in zeolite-Y decreases, meanwhile an absorption band shows up around 840 nm. By photostimulation at 840 nm, fluorescence of silver atoms is detected, which is called photostimulated ...
