Hydrogen Bonding Denticity Governs Surface Modulation in Inorganic Perovskite Nanocrystals

Small, EarlyView.
Organic cations with distinct hydrogen‐bonding denticities enable systematic modulation of perovskite nanocrystal surfaces. Increasing denticity from mono‐dentate MA+ to bi‐dentate FA+ and multi‐dentate GA+ strengthens interactions with surface iodides, effectively suppressing surface defects.

Tetramethylammonium hydroxide (TMAH) treatment of dry-etched trenches on (010) β-Ga2O3 to enhance trench profiles [PDF]

AIP Advances
We demonstrated heated tetramethylammonium hydroxide (TMAH) etching (25 wt. % concentration, at 90 °C) as an effective post-dry-etch treatment for improving dry-etched trench profiles on (010) β-Ga2O3. This treatment successfully converted rough, tapered

Orchestrating Sodium Deposition and SEI Passivation via Bifunctional Mo2TiC2Tx MXene for High‐Efficiency Anode‐Free Sodium Batteries

Small, EarlyView.
A bifunctional Mo2TiC2Tx MXene interlayer is designed to simultaneously regulate sodium nucleation and SEI chemistry on Cu current collectors for anode‐free sodium metal batteries. This synergistic orchestration enables dendrite‐free Na deposition and an inorganic‐rich SEI, delivering over 1400 h of stable cycling and excellent full‐cell performance ...

Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

Small, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...

Formation of Methoxybenzenes from Cellulose in the Presence of Tetramethylammonium Hydroxide by Pyrolysis

Bulletin of the Korean Chemical Society, 2013
Carbohydrates are one of the major groups of organicsubstances on the earth with a simple chemical structurebased on various monosaccharides. They are widespread inplant tissue and can make up about 80% of its dry mass.Recently the pyrolytic characterization of carbohydrates hasgained more and more attention.
