In this protocol, 3-(2-carboxybenzoyl)-1-methyl-1H-imidazol-3-ium chloride [Cbmim]Cl and sulfonic acid functionalized pyridinium chloride [pyridine-SO3H]Cl as a new, reusable, and green Brønsted acidic ionic liquid (BAIL) catalyst were synthesized and successfully used for the one-pot ring opening of epoxide with sodium azide (NaN3) in water at room temperature. Epoxides under ring-opening easi...

Background: Curcumin is yellow pigment of tumeric, and, that is extracted from it lawsonia (2-hydroxy 1,4 naphtoquinon) is a natural product and it is extracted from henna. Ginger is a dried rhizomes gained from a plant called zingiber officinalea, which is extracted from the family of ginger. Material and Methods: This experimental study performed on adult male rats. Acute inflammatory edema ...

sunburn damage is a physiological disorder, which reducing pomegranate fruits quality and result to huge loss to the gardeners yearly. in this study, the effects of kaolin on maintaining fruit quality and decreasing sunburn damage of malas-e-torsh-e-saveh pomegranate was investigated. processed kaolin (surround® wp) with 0, 2.5, 5 and 10 % (w/v) was sprayed over the whole canopy and fruits at 4...

A patient is described who had a long history of abuse of kaolin and morphine mixture which ultimately proved fatal.

Results: Mean ACT value was 180±24 seconds. Femoral hemostasis was achieved with a double suture-based VCD deployment in 30 (67%) patients or a double VCD with cross-over balloon inflation in the remaining 15 (33%) patients. Bleeding after VCDs occurred in 15 (33%) pts. The kaolin-based dressing, activates the intrinsic blood coagulation pathway thus allowing for a short manual hemostasis perio...

The deflocculation effect of conventional additives to kaolin suspensions is evaluated from the results standard rheological measurements. Several widely used electrolytes (NaOH, Na2C03, Na2Si03, SHMP = sodium hexametaphosphate, and CMC = sodium salts of carboxymethylcellulose) have been tested. The optimal concentrations of these deffloculants, in respect to reaching the maximum reduction of i...

Goldfish were trained to press a lever. This response was followed by the delivery of a pellet of food. The fish were then allowed continuous access to the lever under controlled conditions, and their food intake was measured. Goldfish distribute their feeding responses fairly evenly over time, within the limits of the lighting cycle. Some fish eat mainly at night, some during the day, and othe...

A heterogeneous process for the hydrolysis of bamboo into reducing sugars, a process catalyzed by biomass char sulfonic acids (BC-SO3Hs), was carried out under microwave irradiation. This transformation technology was nearly ineffective with regards to the hydrolysis of fresh bamboo because of the impeding lignin that was wrapped around the cellulose, but the hydrolysis proceeded efficiently wh...

Assimilating hydrophilic hollow polymer spheres (HPS) into Nafion matrix by a loading of 0.5 wt % led to a restructured hydrophilic channel, composed of the pendant sulfonic acid groups (–SO3H) and the imbedded hydrophilic hollow spheres. The tiny hydrophilic hollow chamber was critical to retaining moisture and facilitating proton transfer in the composite membranes. To obtain such a tiny cavi...
