“…Because the electric field is formed by the nonmobile, nonannihilative ionic charges, the polarization charges (static and nonmobile) remain in the crystal as long as the stress remains. 28,29) In the piezoelectric field, the PPD draws compensating electrons toward the surface, decreasing the bandgap, whereas the NPD repels electrons from the surface, increasing the bandgap under a compressive strain.…”

Single-atom Pd clusters anchored on t-BaTiO 3 material was synthesized using hydrothermal and ultrasonic methods for the effective piezoelectric catalytic degradation of pollutants using vibration energy. XRD patterns of BaTiO 3 loaded with monoatomic Pd were obtained before and after calcining, and showed typical cubic-phase BTO. TEM and HAADF-STEM images indicated single-atom Pd clusters were successfully introduced into the BaTiO 3 . The piezoelectric current density of the prepared Pd-BaTiO 3 binary composite was significantly higher than that of the pristine BaTiO 3 . Under mechanical vibration, the nanomaterial exhibited a tetracycline decomposition rate of ~95 % within 7 h, which is much higher than the degradation rate of 56.7 % observed with pure BaTiO 3 . Many of the piezo-induced electrons escaped to the Pd-doped BaTiO 3 interface because of Pd's excellent conductivity. Single-atom Pd clusters help promote the separation of the piezo-induced electrons, thereby achieving synergistic catalysis. This work demonstrates the feasibility of combining ultrasonic technology with the piezoelectric effect and provides a promising strategy for the development of ultrasonic and piezoelectric materials.

“…During the heterogeneous photocatalysis process, the liquid flows down through the inner wall of the reactor via gravity and exits the system through a pneumatic valve before returning to the feeding tank. These details were reported in previous studies [45][46][47][48][49][50]. In order to enable the operation of a reactor configuration under both simulated UV and solar irradiation, a pilot plant system was designed and equipped with a concentrating parabolic collector, which is made of anodized aluminum parts due to their high UV irradiation reflectance rates.…”

“…Each sample was streaked on three types of selective agar plates containing corresponding antibiotics including i) (200 μg/mL) streptomycin containing agar plates for counting St R + ATCC 33694 strain, ii) ampicillin (100 μg/mL), kanamycin (50 μg/mL), tetracycline (16 μg/mL) containing agar plates for counting Kan R + , Amp R + , Tet R + E. coli J-53 (DSM-3876) strain and iii) agar plates containing both ampicillin (100 μg/mL), kanamycin (50 μg/mL), tetracycline (16 μg/mL) plus (200 μg/mL) streptomycin antibiotics for counting the Kan R + , Amp R + , Tet R + , St R + multi resistant strain. This way the donor, recipient, and conjugated strains could be counted separately [45,46]. The bacterial culture technique and serial dilutions of the reaction solution were prepared using a sterile 0.8% (w/w%) NaCl aqueous solution.…”

Bu çalışma, antimikrobiyal direncin kontrolünde (AMR) sürdürülebilir yaklaşımlar arasında olan, atıksuyun etkin dezenfeksiyonu üzerine kurulmuştur. Fotokataliz prosesi, ölçeklenebilir, araştırma ve geliştirmeye açık bir ileri oksidasyon prosesidir. Deneysel çalışmalarda kullanılan grafen-oksit-Ti-CuFe2O4 nanokompozit fotokatalizörleri, yeşil bir yaklaşımla sentezlenmiştir. Parabolik kolektör destekli fotoreaktörde, sub-letal fotokatalitik oksidasyonun alıcı ve verici E. coli suşları arasındaki konjugatif gen transferi mekanizmasına etkileri deneysel olarak araştırılmıştır. Farklı fotokatalizörlerin bakteri inaktivasyon hızı üzerine etkisi yanında, alıcı suşlarda eşleşmiş çiftlerin oluşumu (transkonjugant) frekansını ve nihai miktarını azaltan bir etki gösterdiği ortaa konulmuştur. Alıcı ve verici suşların eşzamanlı olarak fotokatalitik oksidasyona maruz kalması, her iki suş için de yaklaşık ~3 LOG giderim sağlamış ve transkonjugan oluşumunu kontrol edebilecek koşular oluşturmuştur. Fotokatalizör yüzeyi, reaktif oksijen türleri ve bakteriyel hücrelerin etkileşimi, ARG transferinin kontrolünde belirleyici bir rol oynamıştır. Alıcı hücrelerin canlılığı üzerindeki fotokatalitik oksidasyon mekanizmalarının etkisi, konjugatif ARG transferinin azaltıldığı sürekli işletme sırasında açıkça görülmüş ve transkonjuganların sayısı 102 CFU mL-1'nin altına düşmüştür. Bu çalışma, PC'nin atıksu arıtımında etkili dezenfeksiyon ve AMR kontrolü için potansiyelini göstermektedir."

By summarizing 187 relevant research articles published in 2019, the review is focused on the research progress of physicochemical processes for wastewater treatment. This review divides into two sections, physical processes and chemical processes. The physical processes section includes three subsections , that is, adsorption, granular filtration, and dissolved air flotation, whereas the chemical processes section has five subsections , that is, coagulation/flocculation, advanced oxidation processes, electrochemical, capacitive deionization, and ion exchange.
