Simultaneous control of nanocrystal size and nanocrystal-nanocrystal separation in CdS nanocrystal assembly [PDF]
Pramana, 2005 We report an easy, one pot synthesis to prepare ordered CdS nanocrystals with varying inter-particle separation and characterize the particle separation using x-ray diffraction at low and wide angles.

On ultrasmall nanocrystals [PDF]
Chemical Physics Letters, 2010 Ultrasmall nanocrystals are a growing sub-class of traditional nanocrystals that exhibit new properties at diameters typically below 2 nm. In this review, we define what constitutes an ultrasmall nanoparticle while distinguishing between ultrasmall and magic-size nanoparticles.

Nano Letters, 2015 We demonstrate the facile synthesis of high purity aluminum nanocrystals over a range of controlled sizes from 70 to 220 nm diameter with size control achieved through a simple modification of solvent ratios in the reaction solution. The monodisperse, icosahedral, and trigonal bipyramidal nanocrystals are air-stable for weeks, due to the formation of a

Emergence of Impurity-Doped Nanocrystal Light-Emitting Diodes
Nanomaterials, 2020 In recent years, impurity-doped nanocrystal light-emitting diodes (LEDs) have aroused both academic and industrial interest since they are highly promising to satisfy the increasing demand of display, lighting, and signaling technologies.

Ultrafast spectroscopy studies of carrier dynamics in semiconductor nanocrystals
iScience, 2022 Summary: Semiconductor nanocrystals have become ubiquitous both in scientific research and in applied technologies related to light. When a nanocrystal absorbs a photon an electron-hole pair is created whose fate dictates whether the nanocrystal will be ...

Absorption enhancement in 2D nanocrystal superlattices through near-field dipolar coupling: a novel optical phenomenon at the nanoscale [PDF]
, 2013 We demonstrate giant and broadband enhancement of the nanocrystal absorption cross section in close packed nanocrystal superlattices, which is the first report on a collective optical phenomenon in this type of self-assembled metamaterials to ...

Bead milled drug nanocrystal suspensions fine enough to pass through 0.22 μm sterilization filters
JCIS Open, 2023 Nanocrystal suspensions have been introduced to overcome the low bioavailability of poorly water-soluble drug compounds by increasing the dissolution rates. For both injection- and inhalation-based administrations it is important that the suspensions are

Calculation of the state equation and the isobaric size dependencies of molybdenum nanocrystal [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2017 On the basis of the RP-model the equation of state of the bcc-molybdenum nanocrystal has been calculated that accounts its size and shape. It is shown that the isobaric size dependencies of the Debye temperature and the first Grüneisen parameter increase
