UNLABELLED Undoped ZnO, Ce-doped ZnO, and (Li, Ce)-codoped ZnO nanophosphors were prepared by a sol-gel process. The effects of the additional doping with Li ions on the crystal structure, particle morphology, and luminescence properties of Ce-doped ZnO were investigated by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, electron paramagnetic resonance spectro...

String scenarios typically not only predict axion-like particles (ALPs) but also significant amounts of ALP dark radiation originating from the decay inflaton or a more general modulus. In this paper, we study such non-thermally produced relativistic (but massive) ALPs to photons. If are sufficiently highly energetic, contribute $\Delta N_{\rm eff} \gtrsim {\cal O}(0.001)$ and have mass $m_a\gt...

Mono-elemental two-dimensional (2D) crystals (graphene, silicene, germanene, stanene, and so on), termed 2D-Xenes, have been brought to the forefront of scientific research. The stability and electronic properties of 2D-Xenes are main challenges in developing practical devices. Therefore, in this review, we focus on 2D free-standing group-IV graphene analogs (graphene quantum dots, silicane, an...

In today’s world of electronics, nanomaterial applications pose a challenge. The spin coating approach was used to create nanostructured ZnO with wurtzite structure in recent study. Antimony doping, aluminum, and antimony codoping 2.0 percent were make these films. impact doped codoped films on structural, optical properties, morphological has been examined using variety characterization approa...

Characterizing subpopulations of stem cells is important to understand stem cell properties. Tissue-nonspecific alkaline phosphatase (ALP) is associated with mineral tissue forming cells as well as stem cells. Information regarding ALP subpopulation of human periodontal ligament stem cells (hPDLSCs) is limited. In the present study, we examined ALP+ and ALP- hPDLSC subpopulations, their surface...

Members of the ALP/Enigma family of PDZ-LIM proteins play a role in cytoskeletal anchorage and mutations in at least one member of this family are associated with human cardiomyopathy. Here, we describe the analysis of the Caenorhabditis elegans alp-1 gene. alp-1 is predicted to encode the entire nematode ALP/Enigma protein family, consisting of one ALP-related protein with a single LIM domain ...

White organic light-emitting devices OLEDs consisting of ambipolar 9,10-bis 2 -naphthyl anthracene ADN as a host of blue-emitting layer EML were investigated. A thin codoped layer of yellow 5,6,11,12-Tetraphenylnaphthacene rubrene served as a probe for detecting the position of maximum recombination rate in the 4 ,4 -bis 24N ,N-diphenylamino phenyl vinyl biphenyl DPAVBi doped-ADN EML. Due to th...
