Today, powder injection molding (PIM) of powder-polymer mixture is considered as a novel technique for production of various complex shapes and dimensionally small parts. This method is a combination of traditional powder metallurgy and plastic injection molding. Mixing, molding, de-binding and sintering are four important steps of PIM. Unique abilities of this process for plastic part manufacturing consist of complex geometries, controllable properties, excellent dimensional accuracy and minimum material loss without machining. In this paper, the history of PIM technique, processing advantages, required specifications of a proper mixture of powder and polymer system are investigated. Furthermore, significant details of PIM steps are evaluated. Finally, PIM technique is studied from the application standpoint to marketing potentials.

Nanogels are nano-sized hydrogel networks formed by chemically or physically crosslinked polymer particles. Their colloidal stability affords them as good candidates for drug delivery systems. Like nanoparticles, nanogels are injectable and responsive to environmental factors, such as ionic strength, pH, and temperature. Encapsulation stability is an important feature that needs to be addressed when designing a drug delivery vehicle. Accidental leakage of drug molecules during circulation into the healthy cells causes a nearly empty vehicle arrive at the disease site. To solve this problem a nano-carrier as nanogels is introduced. Here, we introduce nanogels, and their important synthesis methods as well as their related properties as drug carriers.

This article is an introduction to adhesive bonding process. The joints in structures are challenged with some limitations such as material size, different types of materials joining together, accessibility and inspection, maintenance, and transportation. Therefore, a proper selection and design of composite bonding is essential. Polymer composites of The structure of the review includes: an overview on various aspects of adhesive bonding and fundamental concepts of adhesion phenomena and then general methods for the preparation of composites surfaces including mechanical and physical preparations. The structural adhesives for bonding of polymer composites and their properties under different conditions are discussed. Finally, the mechanical properties of adhesive joints and effective parameters on the strength of these types of joints are analyzed.

Considering the ever increasing activities in research laboratories of pharmaceutical and agricultural industries to synthesize new compounds, the necessity of designing new processes with greater time efficiency, which may lead to more structural variation seems highly plausible. As part of the dramatic changes associated with the need for preparing compound libraries in pharmaceutical and agrochemical research laboratories, industries search for new technologies allow for the automation of synthetic processes. In practical terms, in addition to designing new equipment, the synthesis must also be designed so that the reactions can be carried out with the equipment. In this context, using polymeric reagents is quite useful. Extraction and chromatographic purification can be avoided by using these reagents, and so robots can carry out all the manipulations required. This review is aimed to highlight some of the most important applications of these promising materials in chemical library generation and synthesis of natural products.

A new generation of shape-memory materials includes those that have found many applications in domestic life as well as in industry. The use of these materials lies in response to external stimuli such as temperature, light, electric or magnetic fields-aligned or changing the pH of a new technique in engineering. Physical properties of the materials, such as changes in shape, color and refractive index are dependent on the use of external stimuli. The materials with shape memory properties in their molecular structure can store their original structure. Materials that exhibit shape memory effect have the ability to change in shape and stay in shape retrieval of temporary and permanent forms towards external stimuli. The shape memory materials find specific applications as smart fibers, heat shrinkable pipes, packaging and medical applications such as self-adjust wires and stents to open the blood vessels. In this paper, an overview is given on the structure and properties of nanoparticle-containing shape memory polymeric materials towards external stimuli.

This paper is a reviewing account on the application of polymeric dyes in textiles. Polymeric dyes are classified as crosslinking polymeric dyes, disperse polymeric dyes, “fiber-reactive” polymeric dyes and acidic polymeric dyes. Excellent color fastnesses and dyeing properties are shown when fibers are treated by these polymeric dyes. Crosslinking polymeric dyes show excellent fixation (reaching 99%); disperse polymeric dyes show excellent light fastness (8 grade); “fiber-reactive”polymeric dyes could form chemical covalent bonds with fiber, exhibiting excellent washing fastness; acidic polymeric dyes showing the same fastness properties as the corresponding monomeric dyes, and furthermore the thermal stability is enhanced.

Ternary polymer blends based on polyamide 6 (PA6)/polycarbonate (PC)/acrylonitrile-butadiene rubber (NBR) were prepared at fixed compositions using a twin-screw extruder. The ternary blends mixed at 240 ̊C of die temperature and 130 rpm of screw speed at different levels of blending sequence (B.S1-B.S2-B.S3). In B.S1, the blending sequence, all components were extruded simultaneously but in B.S2 and B.S3 blending sequences, the produced master batch of PC+NBR and PA6+PC were added to the other absent phase. The mechanical properties of ternary blends were influenced by mixing method and the results of mechanical testing were confirmed using the field emission scanning electron microscopy (FESEM) micrographs.
