The approach was validated in an idealized numerical study and is here tested in a systematically controlled laboratory experiment for real carbonate rocks. In order to obtain statistically meaningful results, we pushed the envelope by testing the prediction of the critical point for the wormholing ...
At the end of incubation period, the first experiment was neutralized by both calcium carbonate and ammonium hydroxide to produce four different types of composted materials; composted rice straw neutralized by calcium carbonate 1B, composted rice straw neutralized by ammonium hydroxide 2B, composted ...
1). As a control experiment, we attempted to polymerize DMA without acid but no conversion was detected by 1H NMR, even after 3 days. These results suggest that neither the RAFT agent nor the monomer (for example, through autoinitiation) alone can be responsible for the initiation of the...
reproduction, and growth ofDaphnia magnain a 21-days experiment. They found that polylactic acid microplastics cause the mortality of 60% individuals exposed to 500 mg/L, while in control the mortality was 5%. The authors also reported decrease in reproductive output and body length in...
Redox catalysts play a vital role in chemical looping oxidative dehydrogenation processes, which have recently been considered to be a promising prospect for propylene production. This work describes the coupling of surface acid catalysis and selective o

Oxidation rate constants of elemental sulfur and zinc sulfide, and a dissolution rate constant of carbonate minerals, were adjusted to fit observations. The proposed model and parameters were then applied, without further calibration, to literature-reported experimental observations of resuspension in an ...
(taste) drinks, soy sauce, vinegar in the maximum amount is 1.0g/kg; in Wine, candy, wine in the maximum amount of 0.8g/kg in the low salt; pickles, sauces, candied fruit, use the largest 0.5g/kg in carbonate; use the largest beverage 0.2g/kg. because of solubility of benzoic ...
In order to solve the difficult problem existing in the improvement of acid-fracturing for carbonates in Tahe oilfield,a solution named composite acid fracturing has been put forward.According to various well conditions and reservoir properties of carbonate reservoir,this paper gives corresponding counterm...
