In this article, Sm2O3 doped Lithium Alumino-borate (LABS) glasses were prepared by melt-quench technique. Physical, structural, thermal and spectroscopic properties are investigated by various techniques. The emission spectra consist of three sharp peaks at 562.5, 599, 645.5 nm within the 4f el...

Bacteria of the genus Alicyclobacillus pose serious quality problems for the juice processing industries that have sought effective alternatives for its control. The present study evaluated the effect of UV-C radiation on the reduction of spores and biofilm formation of Alicyclobacillus spp. on ...

Waste printed circuit board (w-PCB) was used as novel catalyst for the degradation of an azo dye, orange II. Multi-techniques including thermal gravimetric analysis, X-ray diffraction, Fourier transform infrared spectrum and scanning electron microscope were employed to characterize w-PCB. The e...

The adsorption of a textile dye, namely, Indanthrene Blue RS (C.I. Vat Blue 4) onto smectite-rich clayey rock (AYD) and its sulphuric acid-activated products (AYDS) in aqueous solution was studied in a batch system with respect to contact time, pH, and temperature. The adsorbents employed were c...

Oxidation of aqueous solution of C.I. Basic Blue 41 (BB41), which is model azo dye pollutants, was studied in a continuous-flow reactor that was operated between 400 and 650 °C at a fixed pressure of 25 MPa. The total organic carbon (TOC) concentration of BB41 was in the range of 30.60 and 152....

Nanosized, bicomponent TiO2–ZnO powders of varying Ti/Zn ratio, were prepared using an ultrasonic precipitation method and their crystalline structure and surface area were determined using X-ray diffraction and N2 physical adsorption. The nanosized TiO2–ZnO powders displayed high photocatalyt...

The adsorption behavior of the cationic dye C.I. Basic Blue 3 (BB3) from aqueous solution on the cation exchanger Lewatit MonoPlus SP 112 (SP 112), functionalized Dowex Optipore SD 2 (SD 2) and non-functionalized Amberlite XAD 1180 (XAD 1180) polymeric sorbents was investigated in order to ident...

Interactions between cationic dye–cationic surfactant and anionic dye–cationic surfactant systems were investigated in aqueous solutions using spectrophotometric method at 288.15, 298.15, 308.15 and 318.15 K. C.I. Basic Red 9 (BR9) and C.I. Acid Blue 25 (AB25) were used as cationic and anionic...

Cyclodextrin-based materials containing carboxylic groups (CD/CMC adsorbents) are used for the removal of C.I. Basic Blue 9 (BB 9) from aqueous solutions. Studies concerning the sorption kinetics (i.e. the effects of contact time, dye concentration and mass of sorbent) are presented and discusse...

A detailed study of the action of alkali on methylene blue (C.I. Basic Blue 9) and other thiazine dyes was carried out through a combination of UV/visible spectroscopy, thin layer chromatography, mass and NMR spectrometry and computational methods. In 0.1 M aq alkali solution, methylene blue for...

A comparative analysis was performed concerning the removal of two different organic dyes from model aqueous solution using an inorganic oxide adsorbent. The key element of the study concerns evaluation of the influence of the dyes’ structure and their acid-base character on the efficiency of t...

As an adaptor in Toll-like receptor (TLR) signaling pathway, Toll/interleukin-1 receptor (TIR) domain containing adaptor inducing interferon-β (TRIF) mediates downstream signaling cascades and plays important roles in host innate immune responses. In the present study, a TRIF ortholog named Lc-...

Acid mine drainage (AMD) in the coal mining industry is recognized as one of the major sources of environmental damage.

The effect of plantain (Plantago lanceolata L.) ensiled with ryegrass and red clover (GCP) on the milk fatty acid (FA) profile and nitrogen utilization of dairy cows was tested. Diet GCP was compared to diets based on ryegrass (G), ryegrass and red-clover silage (GC) and total mixed rations (TMR...

We have previously cloned and characterized the thermostable phytase (PHY US417) from Bacillus subtilis US417. It differs with PhyC from B. subtilis VTTE-68013 by the R257P substitution. PHY US417 was shown to be more thermostable than PhyC. To elucidate the mechanism of how the Pro 257 changes ...
