A method for FGM formation to overcome confinements of its components such as low mechanical strength of bioceramics and the lack of osteoinduction for titanium medical alloys has been disclosed. Spark and plasma sintering have been used to achieve strong and unsplit joint between ceramics layers and alloy. The study has shown that phase composition of both materials remains stable during their heating, while intermediate layer of β-Ti forms on the contact boundary, which increases mechanical strength of the joint. Microhardness testing has confirmed the integrity of composite with retention of strength at ceramics–alloy interface. The lack of defects and internal stress at the boundary of formed junction indicates its high mechanical stability and shows potentiality of method for possible practical application to design contemporary structurally strong implants with improved osteointegration function.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"70 6","pages":"803 - 811"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144868736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A basic bismuth malonate with the composition BiOH(C3H2O4) (compound I) was synthesized, along with two structurally distinct but compositionally identical bismuth malonates containing a water molecule: Bi(C3H2O4)(C3H3O4)H2O (II) and [Bi(C3H2O4)(C3H3O4)]⋅H2O (III).

In compound II, the water molecule coordinates directly to the bismuth atom as a ligand, whereas in compound III this is not observed. Both compounds form one-dimensional (1D) coordination polymers. Upon calcination of compounds II and III at 120°C, anhydrous bismuth malonate with the composition Bi(C3H2O4)(C3H3O4) (IV) is produced via dehydration. All new compounds (I–IV) were characterized by IR spectroscopy, thermal analysis, and powder X-ray diffraction, and their compositions were confirmed by elemental analysis.

The heterostructure 5% Au/Bi2WO6 nanocomposites exhibited the photodegradation for RhB with excellent efficiency of 97.91% under visible light irradiation for 150 min due to the Schottky interface of Au nanoparticles and Bi2WO6 nanoplates and surface plasmon resonance (SPR) effect of metallic Au nanoparticles.
