CoNi nanoparticle-decorated hollow carbon cubes (CoNi-HCCs) were synthesized using ZIF-67 as a sacrificial template. The synthesis utilizes the thermal instability of ZIF-67, creating nanostructures while facilitating carbonization and introducing metal nanoparticles (e.g., CoNi). Prototype Zn–air batteries equipped with CoNi-HCCs exhibited promising discharge potential 1.21 V charge 2.04 at 20 mA cm–2. These values are superior to those Pt–Ru, whose potentials 1.20 2.08 V, respectively....

Doped silicon quantum dots (SiQDs) with defined size, dopant distribution, and surface chemistry are highly sought after as a scientific curiosity because their unique properties offer wide array of potential applications including multimodal medical imaging photovoltaic devices. This report describes diffusion-based postsynthesis doping method for incorporating high concentrations B (2.5–5.0 at. %) into preformed SiQDs predefined sizes while simultaneously maintaining structure morphology....
Doped silicon nanocrystals (SiNCs) are promising materials that could find use in a wide variety of applications. Realizing methods to tailor the surface chemistry these particles offers greater tunability material properties as well broader solvent compatibility. Herein, we report organic-soluble B-doped SiNCs prepared via thermal processing method followed by phosphorous pentachloride etching induced functionalization with alkoxy ligands varied chain lengths. This approach provides...
Abstract Hybrids comprising hollow mesoporous nitrogen‐doped carbon (HMC) nanospheres and metal‐oxide nanoparticles were prepared through a hydrothermal synthesis. These materials exhibit excellent bifunctional catalytic activity in the oxygen reduction evolution reactions (ORR OER, respectively) that are core to efficient operation of Zn‐air batteries. When incorporated into prototype devices, Co 3 O 4 MnCo 2 nanoparticle‐decorated HMC exhibited discharge potentials 1.26 1.28 V at 10 mA cm...

Current LED lights are created with quantum dots made of metals like selenium, tellurium, and cadmium which can be toxic. Silicon is used as a non-toxic substance the second most abundant element in earth's crust. When silicon prepared at nanometer size, unique luminesce optical properties emerge that tuned using sized surface chemistry. Therefore, nanoparticles an alternative emitter for lights. To produce hydride-terminated we must synthesize particles. Hydrogen silsesquioxane (HSQ)...
In this study, we will present the synthesis of self-assembled coupled Au nanorods (NRs) as substrates capable supporting a dual modality surface enhanced spectroscopies, SERS and SEIRAS. The AuNR arrays can be assembled either through vertical alignment or lateral alignment. We different assembly strategies for NRs by adjusting ionic strength NR solution. goal is to rely on self-assembly create organized reproducible sensors small molecule detection.
