Newly obtained benzoxazole and benzimidazole derivatives (1-6) were synthesized in the presence of polyphosphoric acid (PPA) and 6 N HCl, respectively to detect their DNA-damaging activities.
      
Fulleropyrrolidine derivative 2 (R=Me) were hydrolyzed with NaH and methanol in toluene, and then acidified with HCl to result in the corresponding fulleropyrrolidine dicarboxylic acid 3 in a 65% yield (relative to fulleropyrrolidine derivative 2).
      
Volumetric properties of glucose in aqueous HCl solutions at temperatures from 278.15 to 318.15 K
      
Densities have been measured for Glucose + HCl +Water at 10-degree intervals from 278.15 to 318.15 K.
      
Results showed that the morphology of the ZrWMoO8 particles can be simply adjusted by changing the gelling agents, and the thermal expansion coefficients of cubic ZrWMoO8 prepared in HCl solution are -3.84 × 10-6 K-1 from 100°C to 700°C.
      
They were cross-linked and stable in 1 mol/L of HCl and DMF.
      
The study showed that liquefaction could be accomplished with a phenol to bamboo weight ratio of 2-1: 1, a 5% catalyst of HCl or BF3, and a temperature of 115°C.
      
Significant improvements in propylene conversion and cumene selectivity under mild reaction conditions were attained by modification of the catalyst with HCl.
      
A stability study indicated that both crude enzyme preparations exhibited a good stability when exposed to a pH 7.2 tris-HCl buffer at 4°C for 4 h.
      
Denaturation studies in the presence of guanidine hydrochloride (Gn·HCl) were performed using fluorescence and circular dichroism spectroscopy.
      
The study of physicochemical properties of the enzyme showed that it is a homodimer with a subunit molecular weight of 68 ± 2 kD and a pH optimum of 7.5 (in Tris-HCl buffer).
      
The maximal activity of the enzyme was observed in 0.05 M Tris-HCl at pH 8.0 and 50-55°C.
      
Extract from leukocytes was subjected to affinity chromatography on Cp-Sepharose, after which proteins were eluted from the resin with 0.5 M NaCl in Tris-HCl, pH 7.4.
      
The Structure and Energetics of HF(H2O)n and HCl(H2O)n Clusters
      
The Voronoi polyhedrons constructed within the framework of molecular-dynamic model of water clusters are used for the analysis of the hydration of HF and HCl molecules.
      
Conductivity and Electrokinetic Potential of Microcrystalline Cellulose Particles in Aqueous HCl and NaOH Solutions
      
The conductivity of microcrystalline cellulose (MCC) dispersions in aqueous 10-5-10-2 M HCl and NaOH solutions was measured as a function of the particle volume fraction by the conductometry.
      
A coagulation of nanodispersed TiO2 hydrosol mainly consisting of individual anatase nanocrystallites stabilized with HCl was studied.
      
It was shown that only a part of a dispersed phase coagulates when a certain amount of HCl was added to the sol, and larger nanocrystallites are settled first.
      
Can Water Clusters Ionize HCl under the Conditions of Arctic Stratosphere 1.
