Uses cross-linking methacrylic monomer in dental composites, sealants, prostheses, adhesives, artificial nails, printing inks, etc. 

Developments in the u.se of biodegradable polymers in biomedical and surgical applications are reviewed. Applications discussed include tissue engineering, bone fracture fixation devices, resorbable sutures, vascular grafts, temporary barriers for the prevention of postoperative adhesion, artificial skin and systems for controlled drug release. 92 refs. 

The present work was done with the aim to evaluate the efficiency of the acoustic emission method as a diagnostic tool for analysing a carbon plastic composite and its adhesive joints. The samples of the carbon plastic type UKN-5000 were used in the test. Non-defected samples and samples with artificial defects were tested. 

To examine the accumulation effect activity ( A ZT) in the adhesive joints of the carbon plastic, the artificial defects were made. The samples were loaded up to the stress of 0,6"Zf. The test has showed (table 2) that in the weak samples the acoustic emission, at the repeated loading, will start at the point, which is smaller, than initial loading. While, the weaker sample, the bigger value of the "S. ... 

These grass-like and resident instadations require substantial amounts of synthetic materials. A typical sports field covered with artificial turf requires approximately 15,000 kg of fabric, 15,000—30,000 kg of shock-absorbing underpad, and 5,000—10,000 kg of adhesive and seaming materials. The artificial surface for a 0.40-km miming track may require 50,000—70,000 kg of materials. Paint striping and marking of turf, tracks, and courts cad for additional materials. 

Reclaimed mbber, which is widely used in dry mbber, has Htde use in latex compounding. A dispersion or artificial latex of the red aim must be made by a rather expensive process of milling in dispersing agents, eg, soaps and casein, and water. Some reclaim dispersions are used in latex compounds for such things as spread mbber goods and adhesives and fiber binders to reduce cost. However, for most latex compounds, it is not desirable because of the poor physical properties it imparts and the resultant darkening of the compound.

The adhesive cements, or simply adhesives, are viscous liquid preparations used mainly for joining together different objects or parts of objects into coherent units, for sizing (sealing) porous surfaces, and as binders in the preparation of paints (see Textbox 18). Until the end of the nineteenth century the only adhesives known to humans were of natural origin, derived either from vegetable secretions or from animal fluids and tissues. Few modern adhesives are now derived from natural substances most are artificial, human-made (synthetic) substances developed since the twentieth century.

It has been shown that cell adhesion highly depends on the outermost functional groups on SAMs however, cells do not directly interact with the SAMs. Instead, they interact with proteins adsorbed on SAMs. Cell adherence requires an interaction between integral molecules in the cell membrane and glycoproteins specialized for cell adhesion, like fibronectin (Fn) and vitronectin (Vn), which are adsorbed on the artificial material. Thus, the presence of glycoproteins in serum plays a crucial role in cell adherence to artificial materials. In the first part of this review (Sect. 2), we will briefly survey recent studies of cell adhesion on SAMs with different functional groups and discuss the mechanisms involved. 

When a cell suspension is applied to a surface, the events that occur can be conceptually classified into three stages (1) a cell approaches the surface, (2) the cell attaches to the surface, and (3) the cell adheres, and thus, spreads out on the surface. Most studies of cell adhesion on artificial materials measure the number of adherent cells, the cell morphology, and changes in protein expression. To gain more detailed insight into the biophysical mechanism of cell adhesion requires...

Ammonium thiocyanate is used as an ingredient in antibiotic fermentations, pesticides, liquid rocket propellants, adhesives, and matches in photographic processes to improve the strength of silks in the manufacture of transparent artificial resins and as a weed killer and defoliant (Sax and Lewis 1987 Windholz 1983).
