表面积和石墨纳米片的表面积以及粒径对沥青粘合剂Dineshkumar sengottuvelu的修饰，* hashem khalem khaled almashaqbeh，* Mohammed，* Mohammed，Avijit Pramanik，Avijit Pramanik，Grace rushan，Sase ryy，SASE RASEN，SASE RASEN，SASER CHAREN，SASER， G. ucak- Astarlioglu，艾哈迈德·阿斯塔兹（Ahmed al-Ostaz）*摘要：氧化石墨烯（GO）对其独特的物理和化学特性引起了极大的关注。go在包括生物医学，电子，能源和环境在内的广泛领域中找到了应用。它在土木工程中的基础设施材料（例如沥青和水泥）的修饰中也起着重要作用。在这项研究中，我们使用改进的鹰嘴豆菌的方法报告了GOS（GR）粉末和石墨烯纳米片（GNP）的GOS合成。我们广泛研究了GR和GNP前体的粒径和特定表面积对其氧化的影响，这些作用尚未在文献中解决。来自傅立叶转换红外（FTIR）和X射线光电子光谱（XPS）分析的结果表明，由较大的表面积和小尺寸的GR粉制成的GO具有较高的氧化程度，约为9.8％的羧基官能团。这为与不同分子（包括沥青成分）的相互作用提供了更多机会。在这方面，我们通过旋转粘度，流变学，多重应力蠕变和恢复（MSCR）以及抗老龄化性能测量结果研究了富含羧基的GO（较高氧化百分比）对沥青粘合剂高温性能的影响。我们的实验结果表明，从GR粉末前体（指定的OX-GR）获得的GO可以显着改善沥青粘合剂的高温性能。例如，在高温下，仅引入2 wt。％的％进入性能等级沥青粘合剂（PG 67-22）可以大大增加其复杂的剪切模量（G*），并减少相角（δ）。MSCR测试表明，加入沥青粘合剂的添加有效地减轻了其永久性变形并改善了其弹性反应，这证明了蠕变合规性（𝐽𝐽𝑛𝑛𝑛𝑛）的降低约39％，而Go-Modiedified Binder的恢复百分比（𝜀𝜀𝜀𝜀）的恢复百分比（𝜀𝜀𝜀𝜀）增加了297％。此外，测得的粘度衰老指数和G*的G*比率证实了GO在粘合剂抗衰老特性改善的显着影响。关键字：石墨，石墨烯纳米片，石墨烯氧化物，悍马方法，沥青粘合剂，流变

全球不透水表面积扩展的大量陆生碳排放
在过去的三十年中，全球不透水的表面积（ISA）增加了一倍以上，但是由于现有的土地碳储存的耗尽而导致的相关碳排放量仍然未知。在这里，我们报告说，由于全球ISA的扩张，生物质和顶部土壤的碳损失（0 - 30厘米）在1993年至2018年间，每年达到46 - 75 tg c，占同时人类土地使用变化的3.7 - 6.0％。对于UNFCCC的附件I国家，我们的估计排放量可与国家温室气体库存报告的定居扩张所产生的碳排放相媲美，从而提供了这种独立的验证。在研究期间，非恋国家中日益增长的排放量与附件I国家中的排放量减少之间的对比可以通过观察到的新兴排放进化模式来解释，这取决于经济发展阶段。我们的研究对国际碳会计和气候缓解具有影响，因为它揭示了以前忽略但通过土地利用效应对ISA扩展到人为碳排放的实质性的影响。
映射新生大脑中皮质厚度和表面积的遗传形态
成人双胞胎神经影像学研究表明，皮质厚度（CT）和表面积（SA）受遗传信息的差异影响，导致其空间上不同的遗传模式和地形。然而，鉴于新生儿到成年人的显着皮质发育，CT和SA遗传形态的产后起源尚不清楚。为了填补这一关键的空白，这项研究始终探讨了遗传信息如何通过利用来自202个双胞胎新生儿的脑磁共振（MR）图像来差异调节CT和SA在新生儿大脑中的空间拓扑，而复杂的后环境环境因素具有最小的影响。我们利用了婴儿使用的计算工具和数据驱动的光谱聚类方法，将脑皮质构成纯粹的区域，纯粹根据CT和SA的皮质顶点的遗传相关性，并因此创建了第一个基因知情的Cortalical Parcellatial parcellatial neonatal neonatal saps saps braps braps of CT和SA的遗传相关性。两个遗传细胞图均表现出双侧对称性和分层模式，但具有不同的空间布局。对于CT，具有更紧密的遗传关系的区域表现出一个替代验（A-P）分裂，而对于SA，具有较大遗传接近的区域通常在同一叶中。某些遗传知情的区域在新生儿和成年人之间表现出很强的相似性，尽管SA的内侧表面上的相似性最为惊人，尽管它们在遗传细胞图中的总体差异总体差异。这些结果极大地提高了我们对遗传影响对皮质形态空间图案的发展的理解。
