This paper presents an efficient and realistic approach to seam the 2D panels together into a 3D garment mesh. Our main goal is to be able to seam any kind of panels together robotically without considering the variation of style and geometry. In particular, we are discussing difficult situations with respect to deformations and variation of sewing forces Based on the mass-spring model, two-dimensional panels are seamed together along the seams and then three-dimensional garment meshes are built. Our main contribution is that we add five pairs of sewing forces avoiding undesirable sharp folds. Our approach provides a useful design tool to create 3D garment mesh directly in the 3D space through 2D patterns. It is reasonably easy to incorporate our 3D mesh construction techniques into existing 3D graphics systems because we use standard triangular mesh structures and force-based mass-spring model for cloth animation.

This paper examines the effects of shrink - resist treatment, washing cycle and fabric tightness on the shrinkage properties of plain knitted fabrics made from 100% wool, acrylic/wool (50/50) and acrylic/wool (70/30). It was found that shrinkages of both treated and untreated wool fabrics were negatively correlated to fabric tightness and exceeded the IWS shrinkage limits (5% in length and 8 % in area) after 2 - 5A washing cycle. The effect of tightness was not as obvious with acrylic/wool (A/W) fabrics, but the shrinkage was seen to increase with stages of washing cycle for untreated A/W fabrics with some exceeding IWS standard. By apply.ng the DC 109 shrink - resist solvent treatment, it was identified that by with higher percentage of acrylic fibre blended with wool, shrinkage could be reduced considerably and within acceptable limits.

Chemical programming of macromolecular structures to instill a set of defined chemical properties designed to behave in a sequential and precise manner is a characteristic vision for creating next generation nanomaterials. In this context, biopolymers such as proteins and nucleic acids provide an attractive platform for the integration of complex chemical design due to their sequence specificity and geometric definition, which allows accurate translation of chemical functionalities to biological activity. We envision that chemically reprogrammed hybrid proteins will bridge the vital link to overcome the limitations of synthetic and biological materials, providing a unique strategy for tailoring precision therapeutics. We are particularly interested in the chemical design of protein-derived hybrid polymers and their supramolecular responsiveness, while summarizing their impact and the advancement in biomedicine. Proteins, in their native form, represent the central framework of all biological processes and are an unrivaled class of macromolecular drugs with immense speci fi *** in its denatured, unfolded form, protein serves as a monodispersed, biodegradable polymer scaffold decorated with functional side chains available for grafting with molecules of interest. We show that supramolecular interactions facilitated by stimulus responsive chemistry can be intricately designed as a powerful tool to customize protein functions,stability, activity profiles, and transportation capabilities. In addition to proteins, nucleic acids as another class of biomacromolecules have proven extraordinarily useful as a construction material for the fabrication of nanoscale systems. Even large sophisticated nanostructures can be readily constructed by modulating the self-folding of DNA molecules, which is known as DNA origami technology. In this aspect, we have achieved hybrid material combining the programmable properties of DNA and the flexible physical property of polymers wh

A fluorogen named 1-decyl-1-methyl-2,5-bis{4-[(N,N-diethylamino)methyl]phenyl}-3,4-diphenylsilole (3) was synthesized. It emitted weakly as isolated molecule but strongly as supramolecular aggregate, showing a characteristic behavior of aggregation-induced emission (AIE). The molecules of 3 formed highly emissive nanoparticles in aqueous media, which quickly and selectively marked cytoplasm of HeLa cells and posed no toxicity to the living cells. The fluorogen is thus a promising candidate mate-rial for cell imaging as a sensitive, selective and cytocompatible biosensor.

An approach for the economic analysis of chemical product design is proposed. It takes into account of customers' preference on product quality and economic considerations such as pricing, profit, market share, capital investment, and operating cost. The activities needed to support business decision making – identify.ng product quality, estimating product cost, calculating financial metrics, and performing make–buy analysis – are *** design of a Ganoderma lucidum dietary supplement, a traditional Chinese medicinal(TCM) product, is used to illustrate all the activities in this approach.
