Abstract:

Shewanella oneidensis MR-1 was found to reach 99.36% and 78.25% decolorisation for Methyl Orange and Acid Yellow 199 in solutions, respectively. The suitable pH range for decolorisation of Methyl Orange and Acid Yellow 199 by S. oneidensis MR-1 was 4.0–7.0 and 6.0–8.0, respectively, The azo dyes' removal by S. oneidensis MR-1 was slightly enhanced by addition of Mg2+, but inhibited by Pb2+, Cd2+, Cu2+, Fe3+ and Fe2+. The enzyme activities of NADH-DCIP reductase and azoreductase were 2.67 and 3.0 times higher, and 1.92 and 2.48 times higher, respectively, in the Methyl Orange treatment and in t

Abstract:

Nail polish, in particular gel nail polish, is the most used cosmetic product. The components of the gel polish, which determine both toxicity and consumer color properties, are pigments. Zn-Al layered double hydroxides intercalated with anionic food dyes are promising pigments for use in gel polish. The parameters of the samples of Orange Yellow S-intercalated Zn-Al (Zn:Al=4:1 and Zn:Al=2:1) hydroxides synthesized at pH=8 and pH=11 were studied. The crystal structure of the samples was studied by X-ray phase analysis and thermogravimetry, and the pigment properties – by the method of me

Acaudina rosettis is one of the commercial sea cucumber species that is widely consumed on the east coast of Surabaya, East Java, Indonesia. Although its abundance in nature has begun to show signs of decreasing, studies on this species are still very limited. This study aimed to examine indicators that can be used to determine the sex of A. rosettis individuals. Acaudina rosettis samples were collected from Madura strait in the mid of Hijri month for three months. The sea cucumber samples were then dissected. Body wall without viscera and gonads was weighed.

Abstract:

In recent years, some sapphires were found to fade in sunlight and to increase their color after UV irradiation. This unstable color phenomenon is attributed to the photochromism of corundum. The photochromic effect seriously affects the grading and evaluation of sapphires, although its mechanism is still uncertain. Here, we performed a set of photochromic experiments on sapphire specimens using a 254 nm shortwave UV light source and a D65 light source (which simulates sunlight) to generate different color states exhibiting characteristic absorption, emission, and excitation spectra.

<strong>Introduction: </strong>According to research, the main etiological cause of oral submucous fibrosis is areca nut. Epidemiology studies currently being conducted (OSF). Submucosal fibrosis, which affects the majority of the oral cavity, pharynx, and upper third of the oesophagus, is the disease’s hallmark. Detecting collagen fibres in tissues has traditionally relied on stains like Van Gieson and various forms of trichromes, which rely on differential binding by tissue. These stains can distinguish between thick and thin fibres under polarisation microscopy and can be utilise

AbstractSynthesis of bismuth oxide synthesis through the precipitation method using H2C2O4 and Na2CO3 precipitating agents, identification of physicochemical properties and its photocatalysis activity for methyl orange degradation were conducted. The bismuth oxide synthesis was undertaken by dissolving Bi(NO3)3.5H2O in HNO3, then added precipitating agents to form precipitate. The results showed that bismuth oxide produced by H2C2O4 precipitating agent was a yellow powder containing a mixture of α-Bi2O3 (monoclinic) and β-Bi2O3 (tetragonal), porous with size of 28-85 μm.

Based on S-shaped terpyridines, a series of yellow, orange, and red-orange light-emitting iridium(iii) complexes has been synthesized. The respective compounds have been prepared by the bridge-splitting method starting from the dimeric precursor complexes [(ppy)2Ir-μ-Cl]2, [(ppy-CHO)2Ir-μ-Cl]2, and [(c6)2Ir-μ-Cl]2. The products have been fully characterized by one- and two-dimensional (1H–1H correlation) NMR spectroscopy, elemental analysis, and MALDI-TOF mass spectrometry revealing the successful coordination of the iridium(iii) centres to the S-shaped terpyridine ligands.

Many species of sphaerodactyl gecko exhibit sexual dichromatism. In particular, dichromatism plays an important role in intersexual signaling for Sphaerodactylus. Furthermore, some species exhibit polymorphism in male color and pattern. Here, we describe a regional male color morph of Sphaerodactylus macrolepis from St. Croix. After generating both mitochondrial and nuclear phylogenies, we found that individuals with the St. Croix-specific yellow/orange head morph are part of the S. macrolepis clade. This distinct color morph likely contributed to the turbulent taxonomic history of the S. macr

The results show that the crystal structure of Sr3SiO5: Eu2+is not changed upon S2- doping. When the doping concentration of S2- is 1 wt%, the phosphor shows the maximum emission intensity, which is higher than that of Sr3SiO5: Eu2+ without S2-. Moreover, the addition
