Multi-Equilibrium Calculations for HF Solution and HF-F^- Solution

Hf Xl: Adaptive Wideband Hf Transmissions

This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high...

Morphology and photoluminescence studies of electrochemically etched heavily doped p-type GaAs in HF solution

Porous GaAs layers have been produced by electrochemical anodic etching of (100) heavily doped p-type GaAs substrate in HF solution. Scanning electron microscopy revealed the presence of etch pits ranging in size from 0.01 to 2 mm and they were strongly dependent on the electrochemical etching conditions. The etch pits chemical composition consists of O, Ga and As whereas the porous structure c...

Pressure induced shifts in HCl/HF and HF/HCI systems

2014 As a sequel to a previous theoretical study of pressure induced lineshifts in the spectra of diatomic molecules pressurized by polar gases, some new experimental results became recently available and are reported in this paper. They concern the shifts in the HF(0-2) band due to HCl, and the HCl(0-1) and HCl(0-2) bands due to HF, for which predictions have been previously published. In the ...

Computational Study on Protolytic Dissociation of HCl and HF in Aqueous Solution

The protolytic dissociation process of hydrochloric acid (HCl) and hydrofluoric acid (HF) is studied using the B3LYP and MP2 methods with the 6-311+G(d,p) basis set in the gas phase and in aqueous solution. To study the phenomena in detail, discrete and discrete/continuum models were applied by placing water molecules in various positions around the acid. The dissociation process was studied us...
