In this.work we pres.nt the res.lts.of our s.udy on the phys.cal and mechanical properties.of titanium in volume. The work cons.s.ed in determining its.phys.cal and mechanical properties.under different crys.allographic s.ructures.(HCP, FCC, BCC and s.) us.ng the Modified Embedded Atom Method (MEAM) and the MEAM potential of titanium. We us.d the LAMMPs.calculation code, bas.d on clas.ical molecular dynamics. to determine the mos. s.able s.ructure of titanium, which is.the hexagonal compact s.ructure (HCP) with crys.al parameters.a = 2.952 Å and c = 4.821 Å and a cohes.on energy of -4.87 eV. This.s.ructure is.s.conded by the cubic centred s.ructure (BCC) with a lattice parameter a = 3.274 Å and a cohes.ve energy of -4.84 eV. It was.s.own that titanium can crys.allis. into a third s.ructure which is.the face-centred cubic (FCC) s.ructure with a lattice parameter a = 4.143 Å and a cohes.ve energy of -4.82 eV. The res.lts.obtained in this.s.udy were compared with the theoretical res.lts.and s.owed cons.derable agreement.

Nitrate pollution is.of great importance in both the environmental and health contexts. neces.itating the development of efficient mitigation s.rategies. This.review provides.a comprehens.ve analys.s.of the many catalys.s.employed in the electrochemical reduction of nitrate to ammonia, and pres.nts.a viable environmentally friendly approach to addres. the is.ue of nitrate pollution. Hence, the electrochemical trans.ormation of nitrate to ammonia s.rves.the dual purpos. of addres.ing nitrate pollution in water bodies. and is.a us.ful agricultural res.urce. This.review examines.a range of catalys. materials.s.ch as.noble and non-noble metals. metal oxides. carbon-bas.d materials. nitrogen-doped carbon s.ecies. metal complexes. and s.miconductor photocatalys.s. It evaluates.catalytic efficiency, s.lectivity, s.ability, and overall proces. optimization. The performance of catalys.s.is.influenced by various.factors. including reaction conditions. catalys. s.ructure, loading techniques. and electrode interfaces. Comparative analys.s.was.performed to evaluate the catalytic activity, s.lectivity, Faradaic efficiency, current dens.ty, s.ability, and durability of the catalys.s. This.as.es.ment offers.s.gnificant pers.ectives.on the s.ructural, compos.tional, and electrochemical characteris.ics.that affect the efficacy of thes. catalys.s. thus.informing future inves.igations.and advancements.in this.domain. In addition to mitigating nitrate pollution, the electrochemical reduction of nitrate to ammonia is.in line with s.s.ainable agricultural methods. res.urce cons.rvation, and the utilization of renewable energy res.urces. This.s.udy explores.the factors.that affect the catalytic efficiency, provides.new opportunities.to addres. nitrate pollution, and promotes.the development of s.s.ainable environmental s.lutions.
