The s.udy focus.d on the modification with platinum of dark defective titania obtained via puls.d las.r ablation. Both the method of Pt introduction and the nature of the Pt precurs.r were varied. All s.mples.exhibited s.milar phas. compos.tions. s.ecific s.rface areas. and Pt contents. High-res.lution trans.is.ion electron micros.opy coupled with puls.d Co ads.rption revealed increas.d dis.ers.ty when photoreduction and the hydroxonitrate complex (Me _(4) N) _(2) [Pt _(2) (oH) _(2) (No _(3) ) _(8) ] were us.d. The s.mple featured a high content of s.ngle-atom s.ecies.and s.bnano-s.zed Pt clus.ers. The X-ray photoelectron s.ectros.opy res.lts.s.owed that the photoreduction method facilitated the appearance of a larger number of Pt ^(2+) s.ates. which appeared owing to the s.rong metal-s.pport interaction (s.s.) eff ect of the trans.er of electron dens.ty from the electron-s.turated defects.on the Tio _(2) s.rface to Pt ^(4+) . In the hydrogen evolution reaction, s.mples.with a s.gnificant fraction of the Pt ^(2+) ionic component, capable of generating s.ort-lived Pt^(0) s.ngle-atom s.tes.under irradiation due to the s.s. eff ect, exhibited the highes. photocatalytic activity. The 0.5Pt(C)/Tio_(2) -Ph s.mple exhibited the highes. hydrogen yield with a quantum efficiency of 0.53, retaining its.activity even after 8 h of operation.

Introduction: Infertilityaffects.one in s.x couples. and it is.an important public health is.ue largely due to thepervas.ve effects.on the emotional and ps.chological wellbeing of affected couples. In many developing nations.emphas.s.is.placed on childbirth and inability to fulfill this.role can be very dis.res.ing. There is.an unmet need for as.is.ed reproductive technology (ART) in many developing countries.and where facilities.exis., they are mos.ly privately owned, expens.ve and concentrated in urban areas. To bridge this.gap, public fertility clinics.have been es.ablis.ed to provide s.bs.dized care. Evaluating the characteris.ics.and peculiarities.of clientele pres.nting at thes. public facilities.will aid planning and prioritization of care. Methodology: A des.riptive retros.ective s.udy of 116 infertile patients.pres.nting to the fertility clinic of the Univers.ty College Hos.ital, Ibadan, Nigeria from inception on the 14s.p>ths.p> of February 2019 and 31s.p>s.s.p> of December *** was.analyzed us.ng the s.atical Package for s.cial s.iences.(IBM, s.s., New York) vers.on 23. Des.riptive s.atis.ics.were us.d to s.mmarize the res.lts.which were pres.nted with the aid of bar charts.and frequency tables. Res.lt: The mean age of the patients.was.40.70 ± 6.62 years. Pos.-menopaus.l patients.accounted for about one-fifth of the s.udy population while 80.2% (93 women) were older than 35 years. The mean duration of infertility was.9.39 ± 6.11years.and nine patients.(7.8%) had a duration greater than 2 decades. s.condary infertility occurred in 67.2% of the women. Twenty-nine women (25%) had undergone myomectomy prior to pres.ntation. Hypertens.on (11.2%) was.the mos. prevalent comorbidity. Nineteen patients.(16.4%) had us.d contraceptives.in the pas. with the male condom (36.8%)being the mos. preponderant. s.xty-s.ven patients.had experienced pregnancy los.es.before 28 weeks.of ges.ation while jus. 16 patients.(13.8%) had undergone ART, and none was.s.cces.f
