An investigation on modification of natural zeolite with ZnO for the degradation tartrazine. In this study, as a semiconductor is modified into support to form ZnO/zeolite that can increase efficiency Further, formed catalyst was added tartrazine by determining variation in ozonolysis time, amount addition catalyst, and time. The results were determined UV-Vis spectrophotometer at 424 nm. resul...

The use of doses higher than 500 g of Zeolite leads to a dramatic depression of feed intake. Even the effective dose reduces feed intake and induces hypophosphataemia; however, these effects are considered transient. Zeolite may reduce serum Mg but this is without physiological significance. Serum levels of copper and zinc as well as milk yield and composition are not affected by Zeolite treatm...

Hitherto zeolite formation has not been fully understood. Although electrochemical impedance spectroscopy has proven to be a versatile tool for characterizing ionic solutions, it was never used for monitoring zeolite growth. We show here that EIS can quantitatively monitor zeolite formation, especially during crucial early steps where other methods fall short.

The antibacterial activity of natural zeolite (CLI) containing 2.60 wt. % Cu 2+ (Cu-CLI) or 5.07 wt.% Ag + (Ag-CLI) were tested against clinical isolates of Acinetobacter baumannii. A. baumannii belonging to the European clone I and II were isolated in Split University Hospital, Croatia. The isolate from clone II was more sensitive on the effect of the metalloaded zeolite than isolate of clone ...

A d-dimensional zeolite is a d-dimensional body-and-pin framework with a (d+1)-regular underlying graph G. That is, each body of the zeolite is incident with d+1 pins and each pin belongs to exactly two bodies. The corresponding d-dimensional combinatorial zeolite is a bar-and-joint framework whose graph is the line graph of G. We show that a two-dimensional combinatorial zeolite is generically...

High-quality TMA-A zeolite nonocrystals were synthesized using a hydrothermal method from a Al(i-pro)3 : 2.2 TEOS : 2.4 TMAOH : 0.3 NaOH : 200H2O composition. The average size of the zeolite crystal used was 60-130 nm with a lattice constant of 12.389 Å. The well-oriented self-assembled monolayers of zeolite with a face parallel to the glass surface treated with the 4-diisocyanates (DIC-4) show...

Chiral zeolitic materials with intrinsically chiral frameworks are highly desired because they can combine both shape selectivity and enantioselectivity. In the field of zeolite, the synthesis of chiral polymorph A of zeolite Beta or chiral polymorph A-enriched zeolite Beta is one of the biggest challenges. We demonstrate here a generalized extremely concentrated fluoride route for the synthesi...

Zeolites are microporous crystalline materials with highly regular framework structures consisting of molecularsized pores and channels. The characteristic framework type of a zeolite is conventionally defined by combining information on its coordination sequences, vertex symbols, tiling, and transitivity information. Here we present a novel knowledge-based approach for zeolite framework type c...

Ammonia occurs in marine waters including effluents, receiving waters, and sediment interstitial waters. At sufficiently high concentrations, ammonia can be toxic to aquatic species. Toxicity identification evaluation (TIE) methods provide researchers with tools for identifying aquatic toxicants. For identifying ammonia toxicity, there are several possible methods including pH alteration and vo...

Over the years, many strategies have been developed to address the problem of sintering of nanoparticle catalysts, including encapsulating metal nanoparticles in protective shells, and trapping nanoparticles in the cavities of certain zeolites in post-synthesis steps. In general, materials that contain metal nanoparticles that are only accessible via zeolite micropores are intriguing, specifica...
