NiFe 2 O 4 spinel – phosphate (Bi-Ba-Li) glass composite was synthesized by solid-state reaction. New crystalline magnetic phases was developed inside the glassy matrix through a controlled heat treatment. New NF-LBPB4 magnetic nanocomposite material was study. Complex impedance analysis has shown that mobile ions inside the matrix induce the development of complementary crystalline phases resulting in a composite material with excellent magnetic response. An innovative homemade device was designed to test the nanocomposite magnetic response.

Alloys made with mercury and other metals are known as amalgam. Dental amalgams are important alloys having mercury (Hg≈40-50%) as a main component and include silver (≈22-39%), tin (≈12-18%) and copper (≈2-18%). Considering the content of dental amalgams, due to the combination of silver, tin and copper in the structure, they have high economic value.1,2 The mixing of silver and other elements and mercury is known as amalgamation. During this process, metallic powders are dissolved in the mercury along the surfaces, and this process leads to the formation of new phases in the structure. These new solid phases result in the plastic state of amalgam. At the end of amalgamation, resulting phases are rigid. The metallurgical phases that are occurred as a result of these reactions are shown in detail in Table 1.3 The metallurgical properties belonging to these phases are complex and the final phase varies according to the content of the starting alloy. In case of Ag-Sn alloy containing copper below 4%, amalgam become harder and stronger but more brittle. In contrast, if the alloy contains copper about 4-5%, separate Cu3Sn phases form in the structure. These phases increase the workability of amalgam and decrease the fragility.3 Basic reactions which occur during amalgamation are as follows:

The ultimate challenge for orthopedic surgeons who implant hip prosthesis is providing long-term function of the joint without pain. The most common cause of total hip arthroplasty failure is aseptic loosening mostly initiated by wear particles.1 The current paradigm explains aseptic loosening as an inflammatory response to the wear debris particles produced by prosthetic implants. Wear particles are phagocytosed by macrophages and induce a variety of cytokines that mediate inflammatory response leading to the recruitment and activation of osteoclasts, and eventual implant loosening.2 For over 40 years, the metal-on-polyethylene (MoPE) bearing has dominated the field of total hip replacement (THR). The second generation of metal on metal (MoM) THRs made of CoCrMo alloy was introduced into the market in early 1990s with the aim to eliminate the wear of polyethylene (PE) and therefore, to achieve better long-term clinical results compared to conventional MoPE THRs. MoM artificial hip prostheses showed an extremely low rate of wear of the articulation surfaces. In addition, metal particles that are produced are smaller than PE particles and hence, they may induce less tissue reaction.3–5 However, patients with M-M articulations have increased levels of Co and Cr in the serum and urine, and this has raised concerns about toxicity, mutagenesis and hypersensitivity.6 There are reports from orthopedic registers about increase complications and potential problems of early failure of MoM, often require revision surgery.7,8 Several studies reported soft tissue damages with adverse reaction to metal debris.9

Dimple surface is one of the surface textures that are widely studied today. In general, dimples are already well known from golf ball aerodynamics. In the case of golf balls, the application of dimples is a special form of surface roughness, which shifts the typical dropdown of the flow resistance for blunt bodies into the low Reynolds number range. Initially, the idea was to use dimples for drag reduction.

Magnetic drug targeting can be used for locoregional cancer therapy, although the limitation is minuteness of the induced force. A new and simple procedure to enhance the magnetic force is changing the shape of carrier particles. It has been mathematically proved that exerting much stronger magnetic dipoles to nanowires are more possible than to spheres with the same volume. The magnetic dipole of wires having aspect quotient (ratio of length to diameter) of 3 is higher than the spheres of the same volume. Nanowires with α = 5 have magnetic dipoles 1.95 times greater than the spheres with the same volume. At a fixed radius, the magnetic dipole increases with the volume of the drug carrier. Magnetic targeting depth is an important parameter depending on the aspect quotient α of particles. Calculations show that the depth of targeting can exceed 8.5 cm if a nanowire with 15 nm radius and length larger than 150 nm is used as the drug carrier. This depth is 1.7 times more than that reported by previous authors for spherical particles with the same-volume.

Water pollution is an environmental issue which is gaining global attention in the recent years. The major source of water pollution are the effluents from textile dyeing and finishing industries. Because of drastic changes in customer’s demands, the textile industry is a challenge to use high quantity of dyes and auxiliaries that are necessary for modern textile processing. The used water contains various constituents such as dyes and chemicals which are directly released into the sources of water which gets contaminated and thus resulting in water pollution. The discharge of untreated waste into the water bodies has raised much concern because of potential health hazards associated with the entry of toxic components into the food chains of humans and animals. In our day to day demand for potable water is increasing, which is placing an increasing burden on nature’s availability of water resource, has forced for new and efficient methods for water treatment.

Mining activities and metallurgical processes often introduce considerable amounts of heavy metals to the surrounding environment; especially the nearby water bodies as well as groundwater system.1 High concentrations of most heavy metals are highly toxic to living organisms including humans. Moreover, many heavy metals can accumulate in organisms (i.e., bioaccumulation) and be consumed by other organisms along the food chain.2 among the common heavy metals, cadmium (Cd), which is mostly sourced from zinc refinery, has the highest toxicity to most organisms.3 Inhalation of high levels of Cd in a short period of time can lead to acute flu-like symptoms and lung damages, while long-term exposure to Cd can result in serious kidney, bone and lung diseases.4 In addition, cadmium and its compounds are also known to be carcinogenic.5 Therefore, removing heavy metals, particularly Cd from the contaminated aquatic environment has long been an important challenge.

World produced 1,689 million tonne (Mt) of crude steel in 2017, is increased about 3.8% production with respect to 2016 (1627 Mt). India is a third largest producer of steel in the world which is preceded by China and Japan. Iron and steel industry’s growth in India has been exceptional since last 10 years. India’s crude steel production of year 2017 is 101.4Mt which was 53.5Mt in year of 2007. Correspondingly, the per capita steel consumption in the country was 43kg in the year of 2007 which increased to 65 kg in the year of 2017.1 As per National steel policy 2017 (NSP), estimated domestic steel production of 300Mt will be achieved by 2030–31. Reaching out to this visionary aim, Indian steel plants must have to discontinue outdated technologies, increase their production capacities, uplift the efficiency of operations, implement latest technologies, utilize low–grade raw materials as well as minimize waste generation. Considering all waste materials as an economic asset, Ministry of Steel, Government of India2 will encourage the steel companies to develop a Waste Management Plan for additional impetus on zero–waste or complete waste recycling.
