Comprehensive understanding of the synthesis and formation mechanism of dendritic mesoporous silica nanospheres

Nanoscale Advances, 2020
The interest in the design and controlled fabrication of dendritic mesoporous silica nanospheres (DMSNs) emanates from their widespread application in drug-delivery carriers, catalysis and nanodevices owing to their unique open three-dimensional ...

Low temperature synthesis of NaSICON NaZr2(PO4)3 powders with the assistance of in situ formed mineralizer [PDF]

Processing and Application of Ceramics, 2023
A new approach was developed to prepare NaZr2(PO4)3 (NZP) powders at low temperature of 330°C. The effect of different molar ratios of ZrO(NO3)2 • xH2O to NaH2PO4 • 2H2O on the synthesis of NZP powders was systematically investigated by XRD, FE-SEM, TEM,

Shock formation in electron-ion plasmas: mechanism and timing [PDF]

, 2015
We analyse the full shock formation process in electron-ion plasmas in theory and simulations. It is accepted that electromagnetic shocks in initially unmagnetised relativistic plasmas are triggered by the filamentation instability.

Blue spectra and induced formation of primordial black holes [PDF]

, 1998
We investigate the statistical properties of primordial black hole (PBH) formation in the very early Universe. We show that the high level of inhomogeneity of the early Universe leads to the formation of the first generation PBHs. %The existence of these

Microstructures in phase-inversion membranes. Part I. Formation of macrovoids [PDF]

, 1992
A new mechanism for the formation of macrovoids in phase-inversion membranes is proposed. It is based on the observed difference in type of demixing of a thin film of a polymer solution when immersed in a nonsolvent bath: delayed or instantaneous ...

Subscription Mechanisms for Network Formation [PDF]

Journal of Economic Theory, 2002
The purpose of this paper is to examine a model of network formation with costs where individual benefits from network formation are not known to the planner. A number of theorems and explanations is made for establishment of the proposed model. No numerical experiments are performed.
