- Nitric Oxide (NO) Endows Arylamine-Containing Block Copolymers with Unique Photoresponsive and Switchable LCST Properties
-
The fabrication of materials that are responsive to endogenous gasotransmitter molecules (i.e., nitric oxide, hydrogen sulfide, and carbon monoxide) has emerged as an area of increasing research interest. In the case of nitric oxide (NO), o-phenylenediami

- A plurality of single loop comprising conductors having a melting furnace having an inductor device
-
The inductor of a melting furnace also comprising a crucible, consists of parallel but oblique conductors and forming a wave around the crucible, with at least one descending portion ( 9 ) and one ascending portion ( 10 ). The benefit from this arrangement is that the conductors are at an identical average height and all comprise a portion located at each heating height, which guarantees density uniformity of the currents flowing in the conductors even if the load of the crucible has superimposed regions for which the electrical resistivity is different.

- Two-layer imageable element comprising thermally reversible polymers
-
The present invention includes a two-layer imageable element, including: a substrate, a top layer including a first thermally imageable composition including (a) a first thermally sensitive supramolecular polymer or (b) a thermally imageable composition free of the first thermally sensitive supramolecular polymer; and disposed between the substrate and the top layer, a bottom layer including a second thermally imageable composition, which includes a second thermally sensitive supramolecular polymer. The present invention also includes a method of producing the imaged element.

- Sunblocking polymers and their novel formulations
-
Novel polymeric biologically inert compositions and their intermediates, as well as sunscreen formulations comprising them and making them invisible, are provided for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with other monomers to provide sunscreen polymers as microparticles. The polymer microparticles, once imbibed with carrier compounds, change the refractive index, thus providing invisible sunscreen formulations which offer enhanced protection without adverse physiological effects.

- Pallidium catalysed reactions of allenes, carbon monoxide and nucleophiles
-
Hydridopalladium(II) species generated in situ by oxidative addition of Pd(0) to acetic acid or acidic hydroxyl substrates (phenols, oximes) catalyse the termolecular assembly of allenes, CO and amines (primary, secondary) or oxygen nucleophiles to give methacrylamides or methacrylate esters and derivatives thereof in good to excellent yield.
