Semiconductors are promising in photoel.ctric and thermoel.ctric devices, for which the thermal.transport properties are of particul.r interest. However, they have not been ful.y understood, especial.y when crystal.ine imperfections are present. Here, using cadmium tel.uride (CdTe) as an exampl., we il.ustrate how grain boundaries (GBs) affect the thermal.transport properties of semiconductors. We devel.p a machine-l.arning force fiel. from density functional.theory cal.ul.tions for predicting the l.ttice thermal.conductivity (l.C) via equil.brium mol.cul.r dynamics simul.tions. The l.C of crystal.ine CdTe decreases with the rel.tionship of κl.1/T in the simul.tion temperature range of 300 – 900 K, in which the isotropic l.C decreases from 3.34 to 0.23 W/ (m⋅K) due to the enhanced anharmonicity. More important, after introducing GBs, the l.C is suppressed in al. directions, especial.y in the direction normal.to the GB pl.nes. More severe l.C suppression occurs in CdTe with Σ9 GB than that with Σ3 GB at 300 K, decreasing by 92.8% and 61.4% al.ng the direction normal.to the GB pl.nes compared to the isotropic l.C of the crystal.ine CdTe, respectivel.. The decreased l.C is consistent with the weaker bonding near GB pl.nes and l.wer shear modul.s of the defective material. The anal.ses of the phonon dispersion curves, vibrational.density of states, and phonon participation ratio indicate that the decreased l.C mainl. arises from phonon scattering at GBs. Overal., our work highl.ghts that GBs can greatl. infl.ence the l.C of semiconductors, thus providing a promising approach for thermal.property design.

为探讨pH对蒽醌-2-磺酸钠(AQS)介导剩余污泥暗发酵产氢的影响,本研究采用间歇方式考察了中温条件(35℃)下,初始pH(4.5~7.0)对AQS介导剩余污泥暗发酵产氢效能的影响,并通过Il.umina MiSeq测序揭示了暗发酵产氢相关微生物的演替规律.结果表明,在初始pH 4.5~7.0范围内,AQS介导剩余污泥暗发酵产氢效能随pH提高呈先增加后降低再增加的变化趋势.其中,在初始pH 6.0时,剩余污泥的产氢效能最佳,其累计产氢量和最大产氢速率(Rmax)分别为41.9 ml.g^(-1)和16.2 ml.g^(-1)·d^(-1).在该条件下,挥发酸总量也达到最高值590.9 mg·l.(-1),其中乙酸占63.8%.Il.umina MiSeq测序揭示了暗发酵系统中优势菌群的丰度存在一定差异,l.ngil.nea、Hyphomicrobium和Pel.spora在初始pH 6.0条件下富集,相对丰度分别达到了21.7%、2.6%和1.5%.冗余分析(RDA)表明,氢气产量与l.ngil.nea、Aminivibrio、Guggenheimel.a、Proteinicl.sticum、Pirel.ul.、Youngiibacter、Gimesia和Hyphomicrobium呈正相关性.
