TL;DR: Several two-dimensional projections are shown and techniques to isolate different contributions to the coherent response of semiconductors are demonstrated, which reveal previously unobserved many-body correlations.
Abstract: We demonstrate optical two-dimensional Fourier transform spectroscopy of heavy- and light-hole excitons in GaAs quantum wells. This is enabled by active interferometric stabilization of the excitation pulse separation and of a reference pulse.

TL;DR: In this paper, netted sphere-like CdS nanostructures consisting of the dentritic nanolines were prepared in ethylenediamine using L-cysteine and cadmium nitrate tetrahydrate as precursors by a solvothermal process at 150 °C for 8 h.
Abstract: Netted sphere-like CdS nanostructures consisting of the dentritic nanolines were prepared in ethylenediamine using L-cysteine and cadmium nitrate tetrahydrate as precursors by a solvothermal process at 150 °C for 8 h. The reaction time, the molar ratio of precursors, solvent, and temperature can be used as the additional means to control the size and morphology. The synthesized product was characterized by X-ray powder diffraction (XRD), Fourier transform-infrared (FT-IR) spectroscopy, Field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray fluorescence spectroscopy (EDXS), Transmission electron microscopy (TEM), High-resolution transmission electron microscopy (HRTEM), Electron diffraction (ED), Ultraviolet–visible (UV–vis) spectrometer, Raman spectroscopy, and Fluorescence spectrophotometer. And the possible formation mechanism of the netted sphere-like CdS nanostructures is proposed.

TL;DR: In this paper, the Fourier transform infrared (FTIR) spectrometry was used for biological studies in aqueous solutions and compared with the conventional surface plasmon resonance (SPR) technique operating in the visible range.
Abstract: We discuss the surface-plasmon resonance (SPR) technique based on Fourier transform infrared (FTIR) spectrometry. We explore the potential of the infrared surface plasmon technique for biological studies in aqueous solutions and compare it with the conventional surface plasmon technique operating in the visible range. We demonstrate that the sensitivity of the SPR technique in the infrared range is not lower and in fact is even higher. We show several examples of applying FTIR-SPR for biological studies: (i) monitoring D-glucose concentration in solution and (ii) measuring D-glucose uptake by erythrocytes in suspension. We emphasize the advantages of infrared SPR for studying living cell cultures and show how this technique can be used for characterization of (i) cholesterol penetration into plasma membrane and (ii) transferrin-induced clathrin-mediated endocytosis.

TL;DR: In this article, the Kitt Peak Fourier transform spectrometer was used to record the infrared emission spectrum of the Rydberg molecule XeH in a hollow cathode discharge of 2·2 torr H2 and 0·1 torr Xe.
Abstract: The infrared emission spectrum of the Rydberg molecule XeH was recorded with the Kitt Peak Fourier transform spectrometer. XeH was made in a hollow cathode discharge of 2·2 torr H2 and 0·1 torr Xe. The 0-0 bands of the C 2Π-B 2Σ+ and the D 2Σ+-C 2Π transitions were observed near 3250 cm−1 and 4420 cm−1, respectively. A rotational analysis provides spectroscopic constants for these states.
