The document discusses optimizing the preparation of clove oil nanoemulsions as an effective antibacterial agent. It used the Taguchi method to determine the optimal conditions for producing nanoemulsions with droplets less than 50 nm that are stable and have low polydispersity. The key parameters optimized were clove oil concentration, emulsifier concentration, hydrophilic-lipophilic balance number, and ultrasonication time. The optimal conditions found were 50 nm droplet size, 0.49 polydispersity index, and -40.7 mV zeta potential. Testing showed the optimized nanoemulsion inhibited Escherichia coli and Bacillus cereus at 16 and 32 μg/ml respectively and killed them at 16

1) The study examined the acoustic characteristics of polymer solutions with concentrations ranging from 0-5000 mg/L. It found that the density, acoustic velocity, and acoustic impedance of polymer solutions decrease with increasing concentration, while apparent viscosity increases.
2) The experiments showed that polymer flooding changes the pore space and fluid content of reservoirs, reducing density and acoustic velocity/impedance of fluids in pores due to the presence of polymer, while increasing viscosity.
3) Polymer flooding can make permeability lower in parts with low penetration and higher in parts with high penetration, resulting in a more uneven pore structure.

This study examined the drying kinetics of catalase protein solutions using acoustic levitation. Catalase droplets containing trehalose dried more slowly and formed denser particles compared to catalase-only droplets. Trehalose increased the residual enzyme activity of catalase to 95% while droplets dried at higher humidity showed lower activity. Acoustic levitation is a useful technique for studying single droplet drying kinetics but may not replicate conditions of spray drying.

removal of basic dyes from aqueous solution by adsorption using rice
The present article deals with the removal of two basic dyes MB and MG [i.e. methylene blue and malachite green] from a solution mixture using Rice Husk Ash, an agricultural waste. MB and MG are most commonly used dyes in textile industries and removal of two dyes with higher concentrations from the solution mixture is a typical attempt to solve the real life problem on dye removal. The effects of bed depth, influent concentration, flow rate, pH of the influent solution on breakthrough curve were investigated. Thomas, Yoon-Nelson, Adamas-Bohart and Bed Depth Service Time [BDST] model were used to validate the adsorption performance and breakthrough curves. The removal of dyes at different flow rate [5, 7.5, 10, 12.5 ml/min], bed depths (6, 8, 10 cm), influent concentrations [170, 190, 200, 240 mg/L] and pH value [5.1, 7, 9.2] using Rice Husk Ash as an adsorbent were studied. The experimental results indicated that percentage adsorption of dyes increased with decreasing flow rate, increasing bed depth and lowering of influent concentration. The results further revealed that the percentage removal of dyes in the mixture was 99 %.Adams-Bohart and Thomas model were performed well than the other two models in use.
Yellowing of cotton fabric due to softners -by Labeesh Kumar
Cationic softeners cause more yellowing of cotton fabric than silicone or non-ionic softeners. Testing showed that as the concentration of cationic softeners increased from 5% to 20%, the yellowness index and b-value increased, indicating higher levels of yellowing. The bending length and absorbency time decreased with higher cationic softener concentration, showing increased softness and hydrophobicity. More analysis is needed to determine trends conclusively. The document studied the effects of different types and concentrations of softeners on the yellowing and properties of cotton fabric.

Abstract
This study attempted to focus on some important properties of regular fluorescent disperse dyes on polyester/cotton fabric. A 60/40 p/c blended woven fabric was used to dye only the polyester part in pad-thermosol dyeing process (continuous method) with different concentrations of fluorescent disperse dyes. The selected dyestuff was Terasil Flavine 10GFF belonging to coumarin class of fluorescent dye. This paper mainly aims to investigate Spectral parameters such as Reflectance curve, K/S values (with Kubelka-Munk equation) and Relative strength percentage with different concentrations of fluorescent dyes. Different color fastness properties like wash, water, rubbing, perspiration and light fastness were also assessed to evaluate performance of polyester substrate dyed with fluorescent dyes.
Keywords: Fluorescence, disperse dye, pad-thermosol dyeing, reflectance, k/s value, relative strength, color fastness.
Experiment A- Dye Adsorption Technical Memo
The document summarizes an experiment that tested factors affecting the efficiency of dye adsorption using batch and continuous separation processes. The experiments showed that as resin mass increases, the adsorption ratio (q) decreases, as the resin does not need to reach saturation to adsorb all the dye. To maximize adsorbent usage, it is best to use lower resin masses to take full advantage of the surface area before replacing it. While this leads to a higher q value, there is a tradeoff with a longer adsorption time. The maximum adsorption for the dye and resin combination tested was determined to be 21.69 mg of dye per gram of resin based on Langmuir equation analysis of the batch process results. More

This paper reports application of cetyltrimethylammonium bromide (CTAB) coated magnetite nanoparticles (Fe3O4 NPs) as a novel adsorbent for removal of two types of disperse dyes, including disperse red 167, and disperse blue 183, from wastewater of textile companies. The effect of parameters including type of surfactant, pH of solution, surfactant concentration, and amount of salt, was investigated and optimized. The obtained results showed that the ratio of initial dye concentration to CTAB amounts has critical effect on removal processes so that removal efficiencies higher than 95% can be achieved even at high concentration of dyes as high as 500 mg l-1 when the ratio is optimum. Removal of dyes is very fast, and equilibrium is reached at times less than 10 min even for high concentration of the dyes. Very high adsorbent capacity (as high as 2000 mg g-1) was yielded for maximum tested concentration of the dyes (500 mg g-1). The obtained result was confirmed by thermogravimetric analysis data. This study showed that CTAB coated Fe3O4 NPs is a very efficient adsorbent for removal of dyes from wastewater of textile companies and has high capacity under optimum conditions.Production of nanocurcumin from curcuma xanthorriza roxb. by homogenization

Size exclusion chromatography
Size exclusion chromatography separates molecules based on their size or hydrodynamic radius. It uses a column packed with porous beads that allow smaller molecules to enter the pores while restricting the entry of larger molecules. This results in larger molecules being eluted first from the column followed by smaller molecules. It is commonly used to determine the molecular weight distribution of polymers and to purify proteins, nucleic acids, and other biomolecules.

Plasma treatment can improve properties like mechanical strength, electrical conductivity, hydrophilicity, dyeability, printability, and adhesion. It can also introduce desired functional groups and deposit coatings. Plasma activation of textile surfaces has wide applications including softening, shrink resistance, antistatic finishes, dyeing, bonding, water/oil repellency, sizing removal, antimicrobial finishes, and more.
Artificial saliva sorption for three different types of
This study evaluated the artificial saliva sorption of three types of dental composite resins: Tetric N-ceram (nanocomposite), Arabesk (microhybrid), and Soltaire-2 (polyglass hybrid). Specimens of each composite were stored in three types of artificial saliva or deionized water. The weight changes were measured at various time intervals. Statistical analysis found significant differences in sorption between composites and storage media. Tetric N-ceram showed the greatest weight changes, while composites absorbed more from artificial saliva than deionized water in early time periods, but lost more weight after 21 days. The results indicate artificial saliva interacts more with composites than water,

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
