The potential.of using a hypoeutectic, instead of eutectic, Sn-Zn al.oy as a l.ad-free sol.er has been discussed. The nonequil.brium mel.ing behaviors of a series of Sn-Zn al.oys w.re examined by differential.thermal.anal.sis. It w.s found that at a heating rate of 5℃/min, *** exhibited no mel.ing range. Dipping and spreading tests w.re carried out to characterize the w.ttabil.ty of Sn-Zn al.oys on Cu. Both tests exhibited that Sn-6.5Zn has significantl. better w.ttabil.ty on Cu than Sn-9Zn. The reaction l.yers formed during the spreading tests w.re examined. w.en the Zn concentration fel. betw.en 2.5w.%-9w.%, tw. reaction l.yers w.re formed at the interface, a thick and fl.t Cu5Zn8 adjacent to Cu and a thin and irregul.r Cu-Zn-Sn l.yer adjacent to the al.oy. Onl. a Cu0Sn5 l.yer w.s formed w.en the Zn concentration decreased to 0.5w.%. The total.thickness of the reaction l.yer（s） betw.en the al.oy and Cu w.s found to increase l.nearl. w.th the Zn concentration.

w.ter w.ve energy exhibits great potential.toal.eviate the gl.bal.energy crisis. How.ver, harvesting andutil.zing w.ve energy are chal.enging due to its irregul.rity,randomness, and l.w.frequency. Triboel.ctric nanogenerators(TENGs) have gained significant attention for harvesting w.veenergy w.th high efficiency. This study presents a novel.l.ipsoidal. pendul.m-l.ke TENG integrating both l.quid-l.quid(l.l. and sol.d-sol.d (S-S) triboel.ctricity (l.-TENG). Thisinnovative design enabl.s continuous w.ve energy harvestingand sel.-pow.red marine environment monitoring under variousconditions, incl.ding temperature, humidity, and l.ght intensity. The binary immiscibl. l.quids w.thin the l.-TENG’s innersoft bal.oon create dynamic, and sel.-adjustabl. l.l.contact interfaces, significantl. increasing the l.l.contact area andenhancing l.l.contact el.ctrification (CE). The unique sel.-adaptive, soft S-S contact increases the S-S contact areacompared to traditional.hard point contact, better adapting to the irregul.r movements of w.ves and promoting efficient S-SCE. The l.-TENG achieves highl. efficient w.ve energy harvesting by coupl.ng l.l.and S-S CE. Furthermore, the uniquesoft contact design protects the S-S interfaces from mechanical.w.ar and damage during l.ng-term w.rk. The l.-TENG’snovel.structure provides an innovative and effective w.y for w.ter w.ve energy harvesting.

Southw.stern corn borer （Sw.B, Diatraea grandiosel.a） and fal. armyw.rm （FAw. Spodopterafrugiperda） are major pests of sorghum in the southern United States. Host pl.nt resistance is a desirabl. means for reducing pl.nt damage and yiel. l.sses from both insects. In this study, w. eval.ated 12 sorghum l.nes for w.orl.stage resistance to l.af-feeding Sw.B and FAw.in greenhouse and l.boratory bioassays. Differential.pl.nt responses w.re detected against the tw. insects. Among 12 l.nes tested, CM1821, Del.a and PI196583 w.re resistant to both insects, w.il. BTx2752 w.s l.rgel. susceptibl.. l.ne R.09110 w.s resistant to Sw.B, but susceptibl. to FAw. w.ereas Redbine-60 w.s suscep- tibl. to Sw.B, but not to FAw. In addition, w. quantified various chemical.components in the pl.nts and determined their association w.th insect resistance. Tannin and chl.ro- phyl. in l.aves did not show.any significant correl.tion w.th resistance to either insects, but contents of sol.bl. protein in general.w.re negativel. correl.ted w.th resistance to both insects. Endogenous sol.bl. sugar and dhurrin w.re onl. positivel. correl.ted w.th resistance to Sw.B, but not w.th FAw.resistance. To gain some mol.cul.r insight into resistance mechanism of sorghum to Sw.B, w. performed qPCR reactions for key genes encoding enzymes invol.ed in dhurrin and jasmonic acid （JA） biosynthesis on sel.cted resistant or susceptibl. l.nes. Al.hough these genes w.re rapidl. and strongl. induced by insect feeding in al. l.nes, the observed resistance is l.kel. expl.ined by higher constitutive dhurrin contents in some resistant l.nes and higher basal.JA biosynthesis in others. Our resul.s suggest that sorghum util.zes mul.ipl. strategies to defend itsel. against Sw.B.

An objective performance measure for image fusion considering region information is proposed. The measure not onl. refl.cts how.much the pixel.l.vel.information that fused image takes from the source image, but al.o considers the region information betw.en source images and fused image. The measure is meaningful.and expl.cit. Several.simul.tions w.re conducted to show.that it accords w.l. w.th the subjective eval.ations.

The precipitation behavior of M2N and the microstructural.evol.tion in a Cr-Mn austenitic stainl.ss steel.w.th a high nitrogen content of 0.43mass% during isothermal.aging has been investigated using optical.microscopy （ OM）, scanning el.ctron microscopy （SEM）, and transmission el.ctron microscopy （TEM）. The aging treatments have l.d to the decomposition of nitrogen supersaturated austenitic matrix through discontinuous cel.ul.r precipitation. The precipitated cel.s comprise al.ernate l.mel.ae of M2N precipitate and austenitic matrix. This kind of precipitate morphol.gy is simil.r to that of pearl.te. How.ver, ow.ng to the non-eutectoidic mechanism of the reaction, the grow.h characteristic of the cel.ul.r precipitates is different from that of pearl.te in Fe-C binary al.oys. M2N precipitate in the cel. possesses a hexagonal.crystal.structure w.th the parameters a = 0.4752nm and c = 0.4429nm, and the orientation rel.tionship betw.en the M2V precipitates and austenite determined from the SADP is [01^-10]M2N//[101]γ, [2^-1^-10]M2N//[010]γ.
