In this paper, we demonstrate a tunable periodic hourglass-shaped graphene arrays absorber in the infrared (IR) and terahertz (THz) frequency bands. The effects of graphene geometric parameters, chemical potentials, periods, and incident angles on the pure absorption characteristics are studied by using the Finite Difference Time Domain (FDTD) method. In addition, this paper also analyzes the pure absorption characteristics of bilayer graphene arrays. The simulation results show that the maximum absorption reaches 38.2% for the monolayer graphene structure. Furthermore, comparing the bilayer graphene structure with the monolayer structure under the same conditions shows that the bilayer structure has a tunable dual-band selective absorption effect and has a higher maximum absorption of 41.7%. Moreover, it was found that there are dual-band tunable absorption peaks at 21.6   μ m and 36.3   μ m with the maximum absorption of 41.7% and 11%. The proposed structure is a convenient method which could be used in the design of graphene-based optoelectronic devices, biosensors, and environmental monitors.

<p><a>A small library of “half-sandwich” cyclopentadienylruthenium(II) compounds of general formula [(</a>η<sup>5</sup>-C<sub>5</sub>R<sub>5</sub>)Ru(PPh<sub>3</sub>)(N-N)][PF<sub>6</sub>], a scaffold hitherto unfeatured in the toolbox of antiplasmodials, was screened for activity against the blood stage of CQ-sensitive 3D7-GFP, CQ-resistant Dd2 and artemisinin-resistant IPC5202 <i>Plasmodium falciparum</i> strains, and the liver stage of <i>P. berghei</i>. The best performing compounds displayed dual-stage activity, with single-digit nM IC<sub>50</sub> values against blood stage malaria parasites, nM activity against liver stage parasites, and residual cytotoxicity against mammalian cells (HepG2, Huh7). Parasitic absorption/distribution of 7-nitrobenzoxadiazole-appended fluorescent compounds <b>Ru4</b> and <b>Ru5</b> was investigated by confocal fluorescence microscopy, revealing parasite-selective absorption in infected erythrocytes and nuclear accumulation of both compounds. The lead compound <b>Ru2</b> impaired asexual parasite differentiation, exhibiting fast parasiticidal activity against both ring and trophozoite stages of a synchronized <i>P. falciparum</i> 3D7 strain. These results point to cyclopentadienylruthenium(II) complexes as a highly promising chemotype for the development of dual-stage antiplasmodials.</p>
