We report the synthesis and evidence of graphene fluoride, a two-dimensional wide bandgap semiconductor derived from graphene. Graphene fluoride exhibits hexagonal crystalline order strongly insulating behavior with resistance exceeding $10\text{ }\text{G}\ensuremath{\Omega}$ at room temperature. Electron transport in is well described by variable range hopping two dimensions due to presence localized states band gap. obtained through reduction highly conductive, exhibiting resistivity less...

The issue of whether local magnetic moments can be formed by introducing adatoms into graphene is intense research interest because it opens the window to fundamental studies magnetism in graphene, as well its potential spintronics applications. To investigate this question, we measure, exploiting well-established weak localization physics, phase coherence length L(Φ) dilute fluorinated graphene. reveals an unusual saturation below ~10 K, which cannot explained nonmagnetic origins....

Electrochemiluminescence (ECL) detection has attracted increasing attention as a promising analytical approach. A considerable number of studies showed that ECL intensity can be definitely improved by resonance energy transfer (RET), while the RET efficiency is strongly dependent on distance between exited donors and acceptors. Herein we disclose for first time highly enhanced strategy to promote coencapsulating donor ([Ru(bpy)3]2+)/acceptor (CdTe quantum dots, CdTe QDs) pairs into silica...
Tumor metastasis is attributed to circulating tumor cells (CTC) or CTC clusters.
