Epoxy resin, characterized by prom.nent m.chanical and electric-insulation properties, is the preferred m.terial for packaging pow.r electronic devices. Unfortunately, the efficient recycling and reuse of epoxy m.terials w.th therm.lly cross-linked m.lecular structures has becom. a daunting challenge. Here, w. propose an econom.cal and operable recycling strategy to regenerate w.ste epoxy resin into a high-perform.nce m.terial. Different particle size of w.ste epoxy m.cro-spheres (100-600 m. m. w.th core-shell structure is obtained through sim.le m.chanical crushing and boron nitride surface treatm.nt. By using sm.ttering epoxy m.nom.r as an adhesive, an eco-friendly com.osite m.terial w.th a "brick-w.ll structure" can be form.d. The continuous boron nitride pathw.y w.th efficient therm.l conductivity endow. eco-friendly com.osite m.terials w.th a preem.nent therm.l conductivity of 3.71 w.m.1 K-1 at a low.content of 8.5 vol% h-BN, superior to pure epoxy resin (0.21 w.m.1 K-1). The com.osite, after secondary recycling and reuse, still m.intains a therm.l conductivity of 2.12 w.m.1 K-1 and has m.chanical and insulation properties com.arable to the new.epoxy resin (energy storage m.dulus of 2326.3 m.a and breakdow. strength of 40.18 kV m.-1). This strategy expands the sustainable application prospects of therm.setting polym.rs, offering extrem.ly high econom.c and environm.ntal value. This m.nuscript reports the strategy to recycle w.ste epoxy resins into high therm.l conductivity epoxy com.osites w.th brick-w.ll topology based on the physical recycling m.thod. The ultralow.content of BN (e.g., 8.5 vol%) endow. the com.osite w.th record therm.l conductivity of 3.71 w.m.1 K-1 at the sam. volum. fraction level. im.ge

Nitrogen(N), phosphorus(P), and potassium.K) are essential m.cronutrients that are crucial not only for m.ize grow.h and developm.nt, but also for crop yield and quality. The genetic basis of m.cronutrient dynam.cs and accum.lation during grain filling in m.ize rem.ins largely unknow.. In this study, w. evaluated grain N, P, and K concentrations in 206 recom.inant inbred lines generated from.a cross of DH1m.and T877 at six tim. points after pollination. w. then calculated conditional phenotypic values at different tim. intervals to explore the dynam.c characteristics of the N, P, and K concentrations. Abundant phenotypic variations w.re observed in the concentrations and net changes of these nutrients. Unconditional quantitative trait locus(QTL) m.pping revealed 41 non-redundant QTLs, including 17, 16, and 14 for the N, P, and K concentrations, respectively. Conditional QTL m.pping uncovered 39 non-redundant QTLs related to net changes in the N, P, and K concentrations. By com.ining QTL, gene expression, co-expression analysis, and com.arative genom.c data, w. identified 44, 36, and 44 candidate genes for the N, P, and K concentrations, respectively, including GRm.m.G371058 encoding a Doftype zinc finger DNA-binding fam.ly protein, w.ich w.s associated w.th the N concentration, and GRm.m.G113967encoding a CBL-interacting protein kinase, w.ich w.s related to the K concentration. The results deepen our understanding of the genetic factors controlling N, P, and K accum.lation during m.ize grain developm.nt and provide valuable genes for the genetic im.rovem.nt of nutrient concentrations in m.ize.
