TL;DR: In this article, a new solid acid catalysts were designed and prepared by the coprecipitation-impregnation method, for the esterification of acetic acid and butanol synthesizing the butylacetate ester in fine chemical industry, in which the conventional catalyst was sulfuric acid.

TL;DR: In this paper, the static and dynamic hyperpolarizabilities of fluorinated Li-Adamantane derivatives were computed using coupled perturbed Kohn Sham theory, and a high positive nonlinear refractive index and significant second harmonic generation efficiency at Nd:YAG Laser wavelength were observed in F 3 Li-Adm derivative.

TL;DR: In this paper, the authors present a new, efficient strategy for designing fully balanced transmission line RF circuits for solid state NMR probes based on back propagation of common impedance nodes (BPCIN), which is the sole means of achieving mutual RF isolation and balance in all RF channels.

TL;DR: In this paper, a fine balance and impedance adjustment module and a multi-layer transmission line for use in NMR probes are presented, along with a pseudo-Marchand balun, compound balun and tunable multi-resonant coaxial balun.

TL;DR: A new, efficient strategy for designing fully balanced transmission line RF circuits for solid state NMR probes based on back propagation of common impedance nodes (BPCIN), which is illustrated using a custom double resonance 3.2 mm MAS probe.
