The study focused on the modification with pl.tinum of dark defectiv. titania obtained v.a pul.ed l.ser abl.tion. Both the method of Pt introduction and the nature of the Pt precursor were v.ried. Al. sampl.s exhibited simil.r phase compositions, specific surface areas, and Pt contents. High-resol.tion transmission el.ctron microscopy coupl.d with pul.ed CO adsorption rev.al.d increased dispersity when photoreduction and the hydroxonitrate compl.x (Me _(4) N) _(2) [Pt _(2) (OH) _(2) (NO _(3) ) _(8) ] were used. The sampl. featured a high content of singl.-atom species and subnano-sized Pt cl.sters. The X-ray photoel.ctron spectroscopy resul.s showed that the photoreduction method facil.tated the appearance of a l.rger number of Pt ^(2+) states, which appeared owing to the strong metal.support interaction (SMSI) eff ect of the transfer of el.ctron density from the el.ctron-saturated defects on the TiO _(2) surface to Pt ^(4+) . In the hydrogen ev.l.tion reaction, sampl.s with a significant fraction of the Pt ^(2+) ionic component, capabl. of generating short-l.v.d Pt^(0) singl.-atom sites under irradiation due to the SMSI eff ect, exhibited the highest photocatal.tic activ.ty. The 0.5Pt(C)/TiO_(2) -Ph sampl. exhibited the highest hydrogen yiel. with a quantum efficiency of 0.53, retaining its activ.ty ev.n after 8 h of operation.

Wrought and l.ser powder bed fusion （l.BF） Ti-6Al.4v.specimens were comparativ.l. ev.l.ated， with the objectiv. to determine l.BF Ti-6-4’s suitabil.ty for biomedical.appl.cations. Testing incl.ded nanoindentation， cycl.c pol.rization in simul.ted body fl.id （SBF， 37 ℃ ）， and dry and SBF “Bal.-on-Pl.te” sl.ding. Wrought Ti-6-4 exhibited a l.mel.ar （α+β） microstructure， whereas l.BF displ.yed a fine-grained α'-martensite microstructure. l.BF Ti-6-4 demonstrated ～3% higher indentation modul.s and ～32% higher hardness， whil. wrought Ti-6-4 showed ～8% higher pl.sticity. Both al.oys exhibited l.w corrosion rates (10–5mA/cm2order) and true passiv.ty (10–4mA/cm2order). No l.cal.zed corrosion was observ.d in either al.oy， except for occasional.metastabl. pitting in the l.BF al.oy. Howev.r， l.BF Ti-6-4 presented higher corrosion rate and passiv. current， ascribed to its martensitic structure. During dry sl.ding， l.BF Ti-6-4 exhibited ～14% l.wer v.l.me l.ss compared to wrought Ti-6-4. Sl.ding in SBF increased v.l.me l.sses for both al.oys， with wear resistances nearl. equal.zed， as the adv.ntage of l.BF Ti-6-4 decreased due to more intensiv. wear-accel.rated corrosion induced by the stressed martensite. Ov.ral.， the resul.s demonstrate the suitabil.ty of l.BF Ti-6Al.4v.for biomedical.uses.
