It is believed that the slow hydrolysis (as the solution is clear and transparent) plays a critical role in developing small-sized particles, which eventually can help in the phase transformation process from rutile ature itsonaencaetsassaer.yHtoowineivtieart,etothoebntauicnleaantiaotansperToicO...
The decision to perform a DCP should not be delayed after it becomes clear that a standard approach is prone to failure as time to recanalization is on average more than two hours longer when DCP was performed [44]. Of note is the substantially higher rate of complications attributed to DCP...
The initial parameters of the chaotic system used in the encryption process of each channel in the color image are related to the plaintext information of the current channel and the other two channels, which made the key space larger. Wei Song and Chong Fu [75] proposed a parallel image-...
Such a reciprocating process is called TCP's self-clocking mechanism and eventually produces a traffic pattern where the packets are sent in bursts and the spacing between the bursts is probably preserved from one round trip to the next. Although the bursts (e.g., split or merged) and ...
The ozone depletion potential (ODP), flammability, toxicity and global warming potential (GWP) are the criteria that need to be considered during the working fluid selection process. Papadopoulos et al. [22] used 15 criteria for the fluid selection; with environmental, safety, physical, chemical ...
A thermo- gravimetric analyzer (TG-DSC, STA449, Netzsch, Germany) was used to study the process of MMC formation under N2 atmosphere using a heating rate of 10 ◦C·min−1 from 25 to 850 ◦C. An X-ray diffractometer (XRD, X'Pert Powder, Panalytical, Netherlands) with Ni-...
The first method is usually a two-step process including the formation of an intermediate product (N,N-dimethyl chitosan) and can be conducted using two different reaction conditions. Whereas, the second method is a one-step process and does not contain any intermediate product, but it can ...
The process was catalyzed by CuSO4 with O2 as an oxidizing agent. The pH of the reaction environment was lower than that of NaOH. It was found that in weaker alkaline conditions, the activity of the oxygen increased [42]. Brandt et al. separated lignin from biomass using a mixture of ...
The synthesis process was optimized using Box-Behnken Design (BBD) based on the three variables: of the substitution levels of phenol by lignin, the average molecular weights of lignin, and the molar ratios of formaldehyde to phenol, aiming to decrease the curing temperature and to improve the ...
In one study, the transcutaneous pins were inserted into the necks of the right and left condylar process of the mandible and the supraorbital ridge to track the position of the condyle [16]. Other proposed approaches to minimize change in condylar position include the removal of the ...
