Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

The role of adjuvant therapy after resection of T1 N1 M0 and T2 N1 M0 non–small cell lung cancer

The Journal of Thoracic and Cardiovascular Surgery, 1986
Thirty-four consecutive patients with non-small cell lung cancer plus N1 nodal metastases (eight with T1 N1 M0 and 26 with T2 N1 M0) were retrospectively reviewed. Nineteen had adenocarcinoma, 11 had squamous disease, and four had large cell carcinoma. Eleven patients had surgical resection alone (32.3%), with a median survival of 13 months.

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

Advanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

The first near infrared detection of XTE J1118+480 in quiescence

, 2005
We report the first quiescent detection of KV UMa, the optical counterpart of XTE J1118+480 at near infrared. The observed magnitudes and colours are consistent with a K7-M0 V star, at the distance 1.4 +/- 0.2 kpc.
