“…Increasing the duration of LTP treatment of mineral particles to t treat = 300 s caused the electrokinetic potential of ilmenite to rise to the initial negative values of −67.6 mV. The ilmenite's microhardness fell monotonically (from 671.4 MPa in the initial state to 587 MPa at t treat = 150 s) as the duration of treatment of the polished sections of the mineral grew (t treat = 10-150 s), due to such factors of DBD radiation as its strong electric field, the elevated temperature of the dielectric barrier, and the concentration of electric charge on a sample's surface [15,29]. Relative drop in microhardness ∆HV max was ~13%, which is much lower than the recorded effect of disintegration upon exposure to HPEMPs.…”

A study is performed of the mechanism behind the effect high-voltage nanosecond electromagnetic pulses and dielectric barrier discharges have on surfaces of ilmenite in air at atmospheric pressure. Fourier-transform infrared spectroscopy, scanning electron microscopy, electron microprobe analysis, microhardness testing, contact angles of surface wetting, and streaming potentials are used to examine the morphology of ilmenite, its physicochemical properties (microhardness, contact angle, and electrokinetic potential), and the structural state of ilmenite surfaces. Advantages are shown of using brief energy treatments (t treat = 10-30 s) to modify the chemical structure of surfaces of ilmenite and its physicochemical properties in order to improve the efficiency of processing complex titanium ores.

“…Regarding the choice of exposure time, short times of 1 and 10 min were chosen for more preferable implementation in practical applications. Treatment with plasma and discharge products with long exposure times of up to 60 min were previously studied by our group [38,39]. However, processing reasonable amounts of seeds for use in real applications is difficult at long exposure times.…”

This work compares the presowing treatment of winter wheat seeds with a low-temperature plasma, a constant high-voltage electric field, a plant protection disinfectant, and cold hardening on the resistance of seedlings to freezing and their morphophysiological characteristics at the initial stage of germination. Various treatment combinations were considered, including the effect of the disinfectant jointly with low-temperature plasma treatment. The greatest stimulating effect from the point of view of seedlings’ morphophysiological characteristics was achieved when seeds were cold-hardened. The action of low-temperature plasma is noticeable up to the third day of germination. The treatment with the low-temperature plasma of seeds pretreated and not-pretreated with the disinfectant had a similar effect on the morphophysiological characteristics of seedlings. The plasma treatment and the electric field were combined with each other, i.e., the plasma treatment effects were added to the electric field effects. Resistance to low temperatures was increased with the hardening of seeds treated with the electric field and the disinfectant. Resistance to low temperatures was reduced when treated with the electric field and/or low-temperature plasma after being treated with the disinfectant.

“…As a result of the action exerted by strong electric field, micro discharge, ozone and chemically active particles ge nerated in the dielectric barrier discharge plasma [17,23], the surface of the test perovskite samples softens and their microhardness decreases with the longer treatment time from HV = 912 to 663 MPa at V t treat t t = 0 and 150 s, respectively. In this manner, the short-term (t treat t t = 10÷30 s) electromagnetic pulses are effective both in disintegration (formation of micro cracks and unsaturated chemical bonds) and in modification of surface structure of perovskite.…”
