The result revealed that the diffraction peak at 11.4°, 28.2°, 29.8° 24.5° and 48.5° corresponds to the presence of layered titanates, brookite and anatase phase in the as-synthesized TNT. In Fig.1b, the diffraction peak values of TNT and x%-CN/TNT (1, 3, 5, 7 and 10%) composite materials at 25.3°, 36.9°, 37.8°, 38.5°, 48.0°, 53.9°, 55.1°, 62.7°, 68.9°, 70.3°, 75.1°, and 76.0° are corresponded to the anatase phase of TNT. In addition all samples shows extra peak at 14.1°, 28.6°, 29.8°, 33.5°, 43.5°, 44.6° and 58.2° are indexed to the crystal planes of metastable TiO2 (B) phase (JCPDS 74-1940). This is because at 500 °C calcination the proton exchanged layered titanates were decomposed into TiO2 (B) phase through dehydration of protonic layered titanates. This transformation has been observed by shifting of diffraction angle of layered titanates from 2θ = 11.4° to higher diffraction angle (2θ =14.1°).

Effect of Fenton’s Reagent Parameters: Photo-Fenton’s process is highly sensitive to the initial H2O2, iron catalyst concentration and pH value. This reagent is extremely producer of .OH radicals and the reaction rate is limited by the .OH generation. Traditionally, hydroxyl radical has been viewed as the workhorse of hydrogen peroxide oxidation systems. Thus, the main source of OH radicals and oxygen depends on the hydrogen peroxide. Fig.
The samples were cut into 200 mm×50 mm size and standard raw cotton fabric with square size (50 mm×50 mm) was coated on the rubbing head and moved with a reciprocating stroke distance of 100 mm along the length of the samples. The contact angles between the fabrics and n-hexadecane were measured after 50, 100, 200, 500, and 1000 times of rubbings. 2.5.10 Washing resistance measurements AATCC1993WOB standard detergent was selected (refer to JISL0217-79103 washing method) with a concentration of 2 g/L, a bath ratio of 1:40, water temperature of 30 °C and time of 5 min. Then, the samples were washed with flowing water twice for 2 min. After dehydration, one washing process was completed.
Density functional theory (DFT) based ab initio calculations were done to monitor the formaldehyde (CHOH) adsorptive behavior on pristine and Pd -decorated graphene sheet. Structural optimization indicates that the formaldehyde molecule is physisorbed on the pristine sheet via partly weak van der Waals attraction having the adsorption energy of about -15.7 kcal/mol. Metal decorated sheet is able to interact with the CHOH molecule, so that single Ni atoms prefer to bind strongly at the bridge site of graphene and each metal atom bound on sheet may adsorb up to four CHOH. The findings also show that the Ni decoration on graphene surface results in some changes in electronic properties of the sheet and its Eg is remained unchanged after adsorption
The silk worms then produce cocoons with bright, luminous hues. This process greatly reduces the use of and wastewater pollution. Conclusion The increasing production of textiles and the related increasing use of dyes warrants the world’s immediate attention due to the striking adverse impacts of fabric dyeing on the environment. It is now widely recognised that vast amounts of fresh water are being consumed and vast amounts of wastewater, largely untreatable, are being generated. Fortunately, the problem has been recognised and alternative dyeing processes are beginning to be used such as DryDye, Air Dyeing Technology and Dye fed silk worms.

It is observed that, as the porosity of the bounding surface increases the velocity also
The eg electron of Mn3+ hops to spin up orbital of oxygen ion. According to Hund’s rule, an orbital can occupy only one electron, the oxygen ion accepts the eg electron of Mn3+ ion by giving its own spin up electron to Mn4+ ion. The basic mechanism in this process is the doping of a d-hole from Mn4+ or electron doping from d-shell of Mn3+ to Mn4+ like Mn3+ via the oxygen, so that the Mn3+and Mn4+ions change places [thker thesis-9,11]. The itinerant eg electron retains its spin up state due to Hund’s rule coupling and therefore, this is conduction with spin memory
These specific peaks are expected to appear at around 1400, 1650, and 3005 cm-1. The last two bands can be observed in Fig. 8. Perkin Elmer’s note  reports comparison of FTIR spectra of biodiesel derived from palm, rapeseed, and soybean oils which shows the intensities of alkene functional groups increase in the order palm < rapeseed < soy. It is consistent with the FTIR data, the ratio of double bonds per chain to average chain length (representing the volume density of double bonds) increases in the order palm < rapeseed <
Ross Nanotechnology’s NeverWet superhydrophobic coating ` It is a technology to coat a hydrophobic layer on cloth. It can effectively reduce contact surface between clothes and water. To compare with other common technologies, this type of technology has a much higher hydrophobicity. Dust resistant technology Dust and dirt are ubiquitous in the field and have a way of invading the exposed areas of cloth, potentially slowing key functions and damaging
