Article Synopsis
  • Research on intercalation and substitution in 2D materials is important for electronics, catalysts, and batteries.
  • The study presents a method to create sulfur-deficient molybdenum sulfide structures and substitute them with copper atoms using a colloidal synthesis approach.
  • Various techniques were used to analyze the effects of copper substitution on the physical properties and hydrogen evolution reaction activity, indicating potential applications in catalysis and energy storage.

The aim of this study was to obtain cellulose and cellulose nanoparticles (CNP) from garlic and agave wastes, as well as elucidating its structure at different scales using microscopy and spectroscopy techniques. Cellulose is isolated by using a sequential extractive process and monitored by CLSM and SEM, while CNP are produced in a high-energy planetary mill. FTIR and XRD confirmed the presence of cellulose type I and CI and D was used to evaluate the size of CNP.

Since the first report of the green emission of 2D all-inorganic CsPb Br , its bandgap and photoluminescence (PL) origin have generated intense debate and remained controversial. After the discovery that PL centers occupy only specific morphological structures in CsPb Br , a two-step highly sensitive and noninvasive optical technique is employed to resolve the controversy. Same-spot Raman-PL as a static property-structure probe reveals that CsPbBr nanocrystals are contributing to the green emission of CsPb Br ; pressure-dependent Raman-PL with a diamond anvil cell as a dynamic probe further rules out point defects such as Br vacancies as an alternative mechanism.
