This study investigates the growth of {100} KDP crystal faces under varying supersaturation conditions 6.2-14.7%. The findings indicate that positions rate maxima differ between experiments where increases or decreases, with higher rates associated decreasing supersaturation. Surface analysis via SEM and AFM revealed resulted in greater roughness. on dependence R(σ) for both types was best described by parabolic power law models, indicating spiral growth. A significant percentage exhibited...
Silicon-based nanoparticles were produced by irradiating a single-crystal silicon target with 10.6 μm nanosecond transverse excited atmospheric (TEA) pulsed CO2 laser in de-ionized water. The effects of the pulse energies and repetition rate studied. To reveal role thermal effects, low has been applied, excluding interaction beam previously generated cavitation bubble. analysis influence showed that increase leads to an nanoparticle size. An explanation such results was proposed importance...
Cotton yarn was oxidized using the various concentrations and pH of potassium permanganate solutions, in order to investigate influence oxidation parameters on chemical, mechanical sorption properties cotton. The progress monitored through weight loss, carbonyl carboxyl group content, tensile strength, moisture sorption, crystallinity change, surface charge morphology modified samples. groups were introduced into cotton up 0.3 mmol·g−1, while loss 5%. samples, compared with untreated cotton,...
Results of investigations the changes in growth rate inherent to crystals (i.e., independent macroscopic external conditions) during a 15-h period are presented. The results regarding time evolution dispersion also majority were carried out with sodium chlorate crystals, and several experiments potassium dihydrogen phosphate (KDP) Rochelle salt crystals. It was found that, for main occurred initial stage, which extended up 4 h. These rates probably slowly decrease toward end run. Some very...
Abstract A series of novel fulleropyrrolidine–phthalimide dyads was synthesized and their electrochemical self‐assembly properties were investigated. Efficient synthesis acceptor–acceptor performed under microwave irradiation. Fine‐tuning the second redox potentials in achieved by varying length aliphatic spacer (C 2 to C 12 ) between fulleropyrrolidine phthalimide moieties. Shape‐shifting supramolecular polymorphism observed for these compounds during self‐assembly.
Silicon-based nanoparticles are synthesized by picosecond laser ablation in liquid using silicon single-crystal plates as targets. We demonstrated that applying the additional continuous immediately prior to and during changed size distribution oxygen content of produced. This opens up possibility a simple tool for tailoring nanoparticle properties.
Three novel fulleropyrrolidine dumbbells consisting three electron acceptor moieties joined by alkyl linker displaying tunable electrical and morphological properties were synthesized characterized.
The results of investigations {100}, the nongrowing faces sodium chlorate crystals in supersaturated solutions, are presented. It occurred that some did not grow, whereas neighbor same grew. dissolution and refaceting affect probability face appearance reduction range growth rates. Nongrowing very stable; they start to grow at a relatively high supersaturation, by or several simultaneously. order is random, subsequently grown opposite faces. Possible reasons for coexistence growing faces,...
Effects of partial dissolution and refaceting on growth rates sodium chlorate potassium dihydrogen phosphate (KDP) crystals are presented. Under the same external conditions, KDP exhibit rate dispersion (GRD), prior to after refaceting. These GRDs were described by multiple normal distributions. Dissolution reduce GRD. A number pertained higher order maxima decreases, whereas a those lower increases, that is, continue grow at leveled rates. Maxima positions related activity dominant...
Difficulties in determining the crystal growth mechanism from rate versus solution supersaturation dependence are discussed. Obtained results indicate that range of 0.66–1.56%, sodium chlorate crystals grow accordance with spiral model. It is shown 0.44–1.32%, depends on history. Namely, exponent n power law R = Kσn manner changes (varied 1.3 to 1.9%). This indicates overlapping diffusion fields neighboring steps
Silicon nanoparticles (SiNPs) are attracting attention for applications in various fields, from energy storage to bio-imaging. One of their main advantages is good photoluminescence (PL) properties combined with the relatively high bio-compatibility. Here, we fabricated SiNPs by laser ablation silicon single crystal de-ionized water, employing simultaneously picosecond pulse (150 ps, 1064 nm, 7 mJ/pulse) and a continuous wave (CW) (532 270 mW). TEM analysis (bright field TEM, HRTEM, HAADF,...
