Wool in carpets is formed by proteins, where many side chains are polar and ionisable, enabling wool to function as a polymeric ligand exchanger. This project has successfully bound either hydrated ferric oxide (HFO) nanoparticles (Figure 1) or a copper(II) salt onto waste carpet to form a sorbent material. The strongest binding was seen after first modifying the carpet by an alkaline oxidation...

Adhesion of membranes and filaments on periodic rippled surfaces is studied by means of a one-dimensional model. The adhesion behavior is found to depend crucially on the shape of the ripples. Fakir-carpet and sinusoidal patterns are studied in detail. Infinite staircases of periodic ground states are found, with a periodicity diverging at a transition line. Moreover, the boundaries of the regi...

Carpet workers are exposed to different types of health risk factors in different seasons of the year. As the environmental conditions become harsh, risk for developing various types of diseases increases. These problems are further aggravated when the environmental conditions at the workplace deteriorate. An attempt has been made to study the health risk factors in the carpet industry in diffe...

A cross-sectional study was undertaken to determine the health status of children engaged in carpet weaving factories of Jaipur City. Two hundred and ninety school going boys of similar socio-economic status served as controls. A higher prevalence of signs of nutritional deficiencies was observed in carpet weaving children. Analysis of the presenting complaints and the illness suffered in the p...
