Carbon is a versatile element that has allotropes with bothsp2(graphene) andsp3(diamond) bonding. However, none of the allotropes can be used as light-absorber materials in solar cells due to either too large or too small band gap. Here, we propose a novel concept that enables a tunable...

Experimentally, with respect to the (002) peak in benzenoid materials, not all aromatic carbons need contribute to an intermolecular interference peak, so that determinations of sp2 or sp3 carbon abundance based on analysis of only the (002) peak are necessarily flawed. As a separate but ...
以具有C=C双键和咪唑官能团的离子液体为前驱体,通过聚合过程中sp2碳向sp3碳的转化,实现碳前驱体中sp2碳与sp3碳相对含量的控制,然后结合高温热解过程,从而成功地得到sp2碳和sp3碳共存且氮掺杂的三维碳泡沫(CF,Carbon Foam),该三维碳泡沫由薄层的carbon nanosheet组成,表面以sp3碳为主,而且具有微孔和大孔复合的多级...

摘要:哈工大材料学院先进轻合金及纳米功能材料课题组的姜建堂、管振杰等人通过合理的分子结构定制以及选择性结构调控工程在二维碳纳米片中构建了sp2-sp3 C-C极性共价键,显著地提升了碳材料的电磁吸波性能。sp2-sp3 C-C极性共价键诱导的偶极子极化行为对介电损耗具有主要贡献。本文首次揭示了不同杂化形式的同元素原子间...
Oxidative allylation to sp2- and sp3-carbon attached to the nitrogen atom was accomplished. The α-allylation of tertiary amines was catalyzed by easily available hydrated iron(III) chloride in combination with air or aqueous tBuOOH. Remarkably, N-allyl- and N-propagyl-tethered tertiary amines we...
Tunable hybrid sp3 and sp2 carbon composition and pore structures stem from the structure transformation of ionic liquids to polymerized organics and introduction of Co metal salt. Through tuning both composition and pores, the 3D Nヾoped nanocarbon with a high ratio of sp3/sp2 on the surface ...
Carbon, sp2‐hybridizedCarbon, sp3‐hybridizedLithographyPatterning, laser‐inducedA new method of laser-induced lithography for direct writing of carbon on a glass surface is described, in which deposition occurs from a transparent precursor solution. At the glass–solution interface where the laser ...
