Plant pesticide residues, such as chinaberry （Melia toosendan） residue and sand cypress （Sabina vulgaris） residue, are pesticidal plant materials discarded after the bioactive ingredient has been extracted with organic solvents. The only option for botanical pesticide residue utilization has been as landfill. Chinaberry residue （CBR） and sand cypress residue （SCR） were collected and composted in Yangling, Shaanxi Province, China. We studied the effects of chinaberry residue compost （CBRC）, CBRC incorporated with Trichoderma viride （CBRCT）, sand cypress residue compost （SCRC）, and SCRC incorporated with T. viride （SCRCv） on the root-knot nematode, Meloidogyne incognita, infesting the balloonflower （Platycodon grandiflorum）. Bioassay results indicated that stock solutions of the CBRCT and SCRCT extracts significantly inhibited egg hatching and caused high larval mortality, followed in degree by the CBRC and SCRC extracts. The CBR and SCR extracts caused very low inhibition of eggs and larvae. Supplementing potting mixtures with these four composts reduced the severity of root galling and increased the proportion of marketable roots. The severity of root galling decreased and the average weight of the marketable roots increased with an increase in all the composts when supplemented at rates from 5 to 30%. CBR- and SCR-supplemented pot soils also inhibited the nematodes, but CBR and SCR applied to the soil had a phytotoxic effect and inhibited balloonflower growth. Supplementing field soil with the composts reduced the severity of root galling and the populations of southern root-knot nematodes in the soil. CBRCT and SCRCT clearly enhanced the average weight of the marketable roots by 30.45 and 26.64%, respectively. Continuous supplementation with CBRCT or SCRCT in the same field significantly enhanced the control of the root-knot nematode, and the populations of nematodes continued to decrease with second inoculations. The populations of total Trichoderma spp. were dis

为解决煤尘污染给环境和工人带来的危害，文中利用瓜尔胶(guar gum, GG)、聚乙烯醇(polyvinyl alcohol, PVA)和丙烯酸(acrylic acid, AA)分子间的氢键相互作用，制备了一种环境友好的新型水凝胶抑尘剂瓜尔胶-聚乙烯醇-丙烯酸(GG-PVA-AA),旨在改善目前水凝胶抑尘剂较差的力学性能与粘结性能。扫描电镜下显示，喷涂该抑尘剂后，GG-PVA-AA能在煤尘颗粒之间形成一层致密的固化膜，将煤粉颗粒粘结在一起。该致密防护结构能有效抑制煤尘的产生和扩散，达到理想的抑尘效果；抗风蚀实验结果表明用GG-PVA-AA粉尘抑制剂处理的煤粉在强风9 m/s侵蚀条件下质量损失为15.9%,可见GG-PVA-AA粉尘抑制剂具有良好的抗风蚀性；此外，分析了抑尘剂/煤体系和水/煤体系的相互吸附过程，可知抑尘剂分子在煤表面的吸附程度比水分子更大，从微观角度揭示了其抑尘机理。

The thermal conductance across the one-dimensional （1D） interface between a MoS2 monolayer and Au electrode （edge-contact） has been investigated using molecular dynamics simulations. Although the thermal conductivity of monolayer MoS2 is 2-3 orders of magnitude lower than that of graphene, the covalent bonds formed at the interface enable interfacial thermal conductance （ITC） that is comparable to that of a graphene-metal interface. Each covalent bond at the interface serves as an independent channel for thermal conduction, allowing ITC to be tuned linearly by changing the interfacial bond density （controlling S vacancies）. In addition, different Au surfaces form different bonding configurations, causing large ITC variations. Interestingly, the S vacancies in the central region of MoS2 only slightly affect the ITC, which can be explained by a mismatch of the phonon vibration spectra. Further, at room temperature, ITC is primarily dominated by phonon transport, and electron-phonon coupling plays a negligible role. These results not only shed light on the phonon transport mechanisms across 1D metal-MoS2 interfaces, but also provide guidelines for the design and optimization of such interfaces for thermal management in MoS2-based electronic devices.
