Recent work on non-conjugated pendant electroactive polymers (NCPEPs) has demonstrated significant impacts of structural parameters such as backbone stereoregularity and the spacer connecting to properties, most notably charge carrier mobilities. Tuning group however not been reported for stereoregular NCPEPs. Here we present a family novel isotactic poly((carbazolyl-alkyl-triazolyl)methyl meth...

A series of competitive inhibitors of carbonic anhydrase II (CAII; EC 4.2.1.1) that consists of oligo(ethylene glycol) units attached to p-benzenesulfonamides with pendant amino acids, H2NSO2C6H4CONHCH2CH2OCH2CH2OCH2CH2NHCOCHRNH3+, have been synthesized and examined using competitive fluorescence assays. Three of the strongest inhibitors, designated EG3NH3+, EG3GlyNH3+, and EG3PheNH3+, have bee...

The first (99m)Tc and (188)Re complexes containing two pendant bisphosphonate groups have been synthesised, based on the mononuclear M(v) nitride core with two dithiocarbamate ligands each with a pendant bisphosphonate. The structural identity of the (99)Tc and stable rhenium analogues as uncharged, mononuclear nitridobis(dithiocarbamate) complexes was determined by electrospray mass spectromet...

On-surface synthesis (OSS) involving relatively high energy barriers remains challenging due to a typical dilemma: firm molecular anchor is required prevent desorption upon the reaction, whereas sufficient lateral mobility crucial for subsequent coupling and assembly. By locking precursors on substrate then unlocking them during we present strategy address this challenge. High-yield based well-...

This study examines and compares three pieces of Renaissance style gold and enamelled jewelry owned by the Walters Art Gallery, Baltimore, MD, USA. These are a 16th century Hat Badge of Adam and Eve, a 19th century Fortitude Pendant and a Diana Pendant presumed to be of the 16th century (The Walters Art Gallery, Jewelry, Ancient to Modern (Viking, New York, 1979)), Ref. [1]. PIXE spectroscopy w...

The ladder graph plays an important role in many applications as Electronics, Electrical and Wireless communication areas. The aim of this work is to present a new class of odd graceful labeling for the ladder graph. In particular, we show that the ladder graph Ln with m-pendant Ln mk1 is odd graceful. We also show that the subdivision of ladder graph Ln with m-pendant S(Ln)  mk1 is odd grace...

Let G be a simple connected graph. The terminal distance matrix of G is the distance matrix between all pendant vertices of G. In this paper, we introduce some general transformations that increase the terminal distance spectral radius of a connected graph and characterize the extremal trees with respect to the terminal distance spectral radius among all trees with a fixed number of pendant ver...

Showdomycin was first isolated from Streptomyces showdoensis by Nishimura and co-workers.1 It is a white crystalline antibotic of empirical formula C9H11N06 which is active against both gram-positive and gram-negative bacteria and is especially active against Streptococcus hemolyticus' and Streptococcus pyogenes.2 Showdomycin possesses significant antitumor activity against Ehrlich mouse ascite...

We report a methodology developed to detect and track stable fluorescent-labeled nanoclay, in polymer-clay nanocomposite films, and in a contact solvent after migration testing. Fluorescein-5-maleimide (fluorescein) or tetramethylrhodamine-5-maleimide (rhodamine) was covalently bonded to organically modified montmorillonite (o-MMT). Fluorescein- and rhodamine-labeled nanoclay showed good therma...
