Evaluation of apparent viscosity of Para rubber latex by diffuse reflection near-infrared spectroscopy.

Rubber recovery from centrifuged natural rubber latex residue using sulfuric acid

Waste latex sludge from centrifuged residue, which is a null by-product of concentrated latex manufacturing, was digested to retrieve the rubber by using sulfuric acid. It was found that the acid concentration and digestion time have an effect on the amount and purity of the retrieved rubber. Sulfuric acid at concentrations of more than 10% by weight with a digestion time of 48 hours completely...

Evaluation of Reflection Optical Imaging Characteristics Using Fluorescence with Near Infrared Wavelength at Different Depths of Tissue Equivalent Phantom

Ciprofloxacin Release Using Natural Rubber Latex Membranes as Carrier

Natural rubber latex (NRL) from Hevea brasiliensis is easily manipulated, low cost, is of can stimulate natural angiogenesis and cellular adhesion, is a biocompatible, material and presents high mechanical resistance. Ciprofloxacin (CIP) is a synthetic antibiotic (fluoroquinolone) used in the treatment of infection at external fixation screws sites and remote infections, and this use is increas...

Analysis of the Modifying Effect of Styrene Butadiene Rubber Latex Copolymer on Strength and Permeability Properties of Structural Light Aggregate Concrete

Polymers not only possess repairing functions concerning the concrete structures, but also due to their properties are used in making different types of polymer cements and improving the matrix structure of cement materials, enhancing the viscosity, mechanical, and stability power of concretes. Today, there is limited knowledge on the use of SBR in structural light aggregate concrete. In the pr...

Study on reflection of human skin with liquid paraffin as the penetration enhancer by spectroscopy.

Optical clearing agents can improve tissue optical transmittance by reducing the diffuse reflection. The reflection on in vivo human skin before and after applying anhydrous glycerol and 30 to 50% liquid paraffin glycerol mixed solution are investigated in this paper. From their visible and near-infrared reflection spectroscopy, all of their diffuse reflections are reduced after applying the ag...
