Layered rare-earth metal oxides, harn.ssin. the dual properties of oxides an. two-dimen.ion.l layered materials, exhibit remarkable thermal stability an. quan.um con.in.men. effects. Therefore, this work adopts the first-prin.iples calculation.combin.d with the Boltzman. tran.port theory to predict the thermoelectric properties of n.Zn.bO compoun.. The coexisten.e of weak in.erlayer van.der Waals in.eraction., robust in.ralayer ion.c bon.in., an. partial covalen. bon.in. leads to remarkable bon.in. heterogen.ity, which en.en.ers pron.un.ed phon.n.scatterin. an. imposes con.train.s on.thermal tran.port alon. the out-of-plan. direction. The weaken.d chemical bon.s in.uced by the an.ibon.in. states, together with the rattlin.-like behavior of the Zn.atom, culmin.te in.the profoun. an.armon.city in.the layered n.Zn.bO compoun.. The weaken.n. bon. an. heavy elemen. con.ribute to the softn.ss of phon.n.modes, which sign.fican.ly dimin.shes the phon.n.group velocity. The redistribution.domin.ted four-phon.n.scatterin. process span. a large optical gap, which effectively reduces the lattice thermal con.uctivity. The n.Zn.bO compoun. exhibits direct semicon.uctor characteristic with a ban.gap of 0.73 e V by adoptin. the Heyd-Scuseria-Ern.erhof(HSE06) fun.tion.l in.combin.tion.with spin.orbit couplin.(SOC) effect. The multi-valley feature of n.Zn.bO compoun. augur favorably for ban. degen.racy, thus amplifyin. the power factor. Con.equen.ly, an.optimal figure-of-merit(ZT) of 3.40 at 900 K is achieved for the n.type n.Zn.bO compoun.. The presen. study delves deeply in.ights in.o the origin. for the low thermal con.uctivity of n.Zn.bO compoun. an. proposes an.optimization.scheme to en.an.e overall thermoelectric performan.e.

Con.en.ration. of Iron.(Fe), As, an.

Then. the prediction.results were evaluated by relative root mean.square error (RRMSE) an. coefficien.s of determin.tion.(R 2 ). Accordin. to the criteria of min.mal RRMSE an. maximal R 2 , the PLSR models with the FD pretreatmen. (RRMSE = 0.24, R 2 = 0.61), Sn. pretreatmen. (RRMSE = 0.08, R 2 = 0.78), an. BC-pretreatmen. (RRMSE = 0.20, R 2 = 0.41) were con.idered as the fin.l models for predictin. As, Fe, an. Cu, respectively. Waveban.s at aroun. 460, 1 400, 1 900, an. 2 200 n. were selected as importan. spectral variables to con.truct fin.l models. In.con.lusion. con.en.ration. of heavy metals in.con.amin.ted soils could be in.irectly assessed by soil spectra accordin. to the correlation.between.the spectrally featureless compon.n.s an.

Cardan.l is a biobased raw material derived from cashew n.t shell liquid. In.order to exten. its utility, n.w derivatives an. addition.l application. are useful. In.this work cardan.l was first epoxidized, an. a n.vel an.lin. derivative prepared from it un.er mild reaction.con.ition. with the help of an.ion.c liquid catalyst. The reaction.chemistry was studied by usin. n.clear magn.tic reso- n.n.e. The resultin. amin.hydrin.adduct showed an.iox- idan. property an. should also be a useful syn.hon.for further reaction.. As an.example, the amin.hydrin.was shown.to un.ergo a con.en.ation.reaction.with formalde- hyde to form a prepolymer, which could be further reacted to form thermosettin. resin..
