Synthesis and Stabilization of Support-Free Mesoporous Gold Nanoparticles
Nanomaterials, 2020 Porous gold nanoparticles (PGNs) are usually prepared in an immobilized form on a solid substrate, which is not practical in many applications. In this work, a simple method is reported for the preparation and stabilization of mesoporous gold particles ...

A spectroscopic examination of accretion diagnostics for near solar mass stars in IC 348 [PDF]
, 2008 High-resolution optical and moderate-resolution near-infrared spectra were obtained for 40 near solar mass (~2.0-0.5 M⊙) members of the 2-3 Myr old cluster IC 348 in order to examine established accretion diagnostics and the coupling between inner disk ...

Advanced Healthcare Materials, EarlyView.Metal‐organic frameworks (MOFs) have been synthesized using calcium (Ca‐MOF), magnesium (Mg‐MOF), and as hybrids (Ca/Mg‐MOF) for bone healing applications. MOFs are integrated into hydrogel polymer networks for injectable, sprayable, and coating applications.

Two-micron spectrophotometry of the galaxy NGC 253 [PDF]
, 1979 A very strong Brackett-gamma hydrogen emission line, and the 2.3 micron CO stellar absorption feature were measured in NGC 253. The presence and strength of the CO feature indicates that late type giant stars produce most of the 2.2 micron continuum ...

Dust yields in clumpy SN shells: SN 1987A revisited [PDF]
, 2006 We present a study of the effects of clumping on the emergent spectral energy distribution (SED) from dusty supernova (SN) shells illuminated by a diffuse radiation source distributed throughout the medium.

Advanced Healthcare Materials, EarlyView.The pyrogallol‐conjugated carboxymethylcellulose (CMC‐PG) hydrogel is applicated as a filler for the treatment of presbylaryngis, a vocal fold atrophy. CMC‐PG provides a bulking effect to the vocal folds. CMC‐PG is readily injectable and tissue adhesive, enabling sustained release of growth factor over long period.

Analysis of Lipids in the Medulla of Japanese Hair and Their Function
Cosmetics, 2018 The hair is composed of the cuticle (the outermost surface), cortex (its major part), and medulla (in the hair center). The lipid content of the medulla of Caucasian hair is relatively higher than that of African-American hair.

An Atlas of Spectrophotometric Landolt Standard Stars
, 2005 We present CCD observations of 102 Landolt standard stars obtained with the R-C spectrograph on the CTIO 1.5 m telescope. Using stellar atmosphere models we have extended the flux points to our six spectrophotometric secondary standards, in both the blue

A Widely-Separated, Highly-Occluded Companion to the Nearby Low-Mass T Tauri Star TWA 30 [PDF]
, 2010 We report the discovery of TWA 30B, a wide (~3400 AU), co-moving M dwarf companion to the nearby (~42 pc) young star TWA 30. Companionship is confirmed from their statistically consistent proper motions and radial velocities, as well as a chance ...

Advanced Healthcare Materials, EarlyView.A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers
