[B(OH)3]0.78[B(OH)2(OSO3H)]0.22 or (BSA) was simply prepared by addition of chlorosulfonic acid to commercial boric acid at room temperature. This cheap and green solid acid was used as an efficient catalyst for synthesis of acylals from aldehydes under solvent-free conditions at room temperature.

We designed a series of anilino-indoylmaleimides based on structural elements from literature JAK3 inhibitors 3 and 4, and our lead 5. These new compounds were tested as inhibitors of JAKs 1, 2 and 3 and TYK2 for therapeutic intervention in rheumatoid arthritis (RA). Our requirements, based on current scientific rationale for optimum efficacy against RA with reduced side effects, was for potent...

We investigated the geometric and chemical factors of nonspherical Janus particles (i.e., Janus ellipsoids) with regard to the pinning and unpinning behaviors of the Janus boundary at the oil-water interface using attachment energy numerical calculations. The geometric factors were characterized by aspect ratio (AR) and location of the Janus boundary (α) separating the polar and apolar regions ...

For speech translation to be practical and useful, speech translation systems should be portable to multiple languages without substantial modi cation. We present the results of expanding the English-based JANUS speech translation system [1] to translate from spoken German sentences to English and Japanese utterances. We also report the results of implementing part of the LPNN speech recognitio...

By combining the specific molecular recognition capability of MIPs and the asymmetric structure of Janus particles, the Janus MIP particles which were synthesized via a wax-water Pickering emulsion showed attractive capabilities as self-propelled transporters for controlled drug delivery.

The chromatoid body in the spermatogenesis of the grass-snake, Natrix natrix, has been studied by the use of phase-contrast microscopy, vital dyes, and histochemical tests. It first appears during the growth of the primary spermatocyte and is also seen in the secondary spermatocyte and late spermatid, but is absent at metaphases of both the maturation divisions, in the early spermatid, and duri...

This paper reports a new simple, sensitive and selective catalytic kinetic spectrophotometric method for the determination of trace quantities of Os(VIII). Janus Green is oxidized by hydrogen peroxide in borate buffer at pH 9.0 and Os(VIII) catalyzes the reaction. Reaction rate was monitored spectrophotometrically at 618 nm. The calibration graph is linear for 0.4 – 430.0 ng mL-1 of Os(VIII) an...

The diffusion of a Janus rod-shaped nanoparticle in a dense Lennard-Jones fluid is studied using molecular dynamics (MD) simulations. The Janus particle is modeled as a rigid cylinder whose atoms at each end have different interaction energies with fluid molecules, thus comprising wetting and nonwetting surfaces. We found that both rotational and translational diffusion coefficients are larger ...
