<p>Nanohybrids, made up of Bismuth ferrites/Carbon allotropes, are extensively used in photocatalytic applications nowadays. Our work proposes a nanohybrid system composed of Bismuth ferrite nanoparticles with two-dimensional (2D) MXene sheets namely, the BiFeO<sub>3</sub> (BFO)/Ti<sub>3</sub>C<sub>2</sub> (MXene) nanohybrid for enhanced photocatalytic activity. We have fabricated the BFO/MXene nanohybrid using simple and low cost double solvent solvothermal method. The SEM and TEM images show that the BFO nanoparticles were attached onto the MXene surface and in the inter-layers of two-dimensional (2D) MXene sheets. The photocatalytic application is tested for the visible light irradiation which showed the highest efficiency among all pure-BFO based photocatalysts, i.e. 100% degradation in 42 min for organic dye (Congo Red) and colorless aqueous pollutant (acetophenone) in 150 min, respectively. The present BFO-based hybrid system exhibited the large surface area of 147 m<sup>2</sup>g<sup>-1</sup>measured via Brunauer-Emmett-Teller (BET) sorption-desorption technique, and is found to be largest among BFO and its derivatives. Also, the photoluminescence (PL) spectra indicate large electron-hole pair generation. Fast and efficient degradation of organic molecules is supported by both factors; larger surface area and lower electron-hole recombination rate. The BFO/MXene nanohybrid presented here is a highly efficient photocatalyst compared to other nanostructures based on pure BiFeO<sub>3</sub> which makes it a promising candidate for many future applications.</p>

Background. Pathological vaginal discharge is the most common disorder in women after giving birth who have vaginal relaxation syndrome and vaginal wall prolapse, as well as in women during menopause. To date, there are no clear treatment regimens for mixed vulvovaginal infections, and the use of only drug therapy in patients with pelvic organ prolapse and genitourinary syndrome of menopause in combination with diseases which are accompanied by pathological vaginal discharge does not give a long lasting result and is characterized by frequent relapses. In this regard, the use of laser methods in combination with drug therapy may lead to the recovery of vaginal microbiocenosis and a decrease in the number of relapses of diseases which are accompanied by pathological discharge from the genital tract. Results. Description. This article presents a clinical case and description of the experience of using a neodymium laser for the treatment of a patient with recurrent mixed vulvovaginitis, 2nd- degree vaginal wall prolapse, loss of pelvic floor muscle tone, vaginal relaxation syndrome and sexual dysfunction using neodymium laser. The woman received 3 procedures of exposure to a neodymium laser with an interval of 2830 days. After 3 procedures of exposure to a neodymium laser, the patient has a good clinical efficacy in the recovery of vaginal microbiocenosis. Conclusions. An innovative technique of exposure to Nd:YAG neodymium laser in the practice of a gynecologist has shown high clinical efficiency in the treatment of not only pelvic floor dysfunction, but also mixed vulvovaginitis. And, despite this aspect of the use of laser technologies requires further study, we can use a neodymium laser in combination with traditional drug therapy to treat diseases which are accompanied by pathological discharge from the genital tract in cases of ineffective drug monotherapy and frequent relapses.
