The single-crystal lithium hydride (LiH) generally grows in a gradient temperature region with the Bridgman method. A stable and appropriate temperature gradient is crucial in the crystallization process. In this paper, the temperature variation of singl
With the gradual increase in the synthesis temperature, other C–S–H with a Si/Ca ratio gradually formed and transformed into the C–S–H crystal with a Si/Ca ratio of 5:6. With the continuous progress of the reaction, the xonotlite-type calcium silicate crystal with a Si/Ca ratio of...
Oscillators that have a frequency determining crystal are commonly used to provide a stable output frequency. However, the crystals used in such oscillators are temperature sensitive and therefore temperature compensating apparatus is normally required to maintain a stable oscillator output frequency. Two b...
Figure 2. Directions of crystallographic axes in FF microtube. We use Porto‘s notation [20]. It is a traditional way to indicate the configuration of the Raman scattering experiment. This notation expresses the orientation of the crystal with respect to the polarisation of the laser in both ...
In the case of the pure trimellitate (EO), nuclei form below the temperature range in which crystal growth is optimal. In case of greases, the thickener creates interfaces at which nuclei can form in the temperature range in which crystal growth takes place. Since nuclei are present, crystal...
In this work, an isotactic polypropylene (PP) and a polyethylene–octene copolymer (POE) have been blended and injection-molded, obtaining solids and foamed samples with a relative density of 0.76. Different mold temperature and injection temperature were used. The Izod impact strength was measured...
increase in BC/PP composites. This is attributed to the nucleation effect of the biochar particles in the PP matrix. It means the biochar particles acted as points from where crystal growth initiated. Similar nucleating effects through incorporation of other carbonaceous fillers into PP matrix has ...
In this paper, we theoretically designed and numerically studied a high-resolution and ultrasensitive photonic crystal fiber temperature sensor by selective filling of a liquid with high thermo-optic coefficient in one of the airholes of the fiber. The finite element method was utilized to study the...
During the coldest half of the year (beginning in October and ending in March), only 25 % of the sunlight hits the earth, while during April to September the remaining 75 % is received. 3.3. Analysis of the Ground Temperature Field Based on the long-term observations at the Small ...
In the montmorillonite structure, because both sides of the crystal layer are composed of oxygen, the force between the crystal layers is an intermolecular force (without a hydrogen bond), which is loosely connected, and water can enter easily. On the other hand, due to the large number of ...
