The structures and properties of hyperbranched silicone oil were characterized through 1H NMR, Thermogravimetry (TG) and dynamic viscosity.
How to improve cushioning properties by adjusting structures of silicon oils is one of major problems.
However, hyperbranched silicon oil’s special branched structure can form more entanglement between molecular chains and it’s not easy to be orientated.
However, due to its special branched structure, hyperbranched silicone oil forms many branching points, which hinder methyl radical to bite back and form ring structure.

In this work, flexible BHJ solar cells were fabricated on an ITO/PET substrate using an inverted PET/ITO/PFN/PTB7:PC71BM/MoO3/Au device structure.
The solar cell structures fabricated in this work were either glass or PET /ITO/PFN/PTB7:PC71BM/MoO3/Au.
A schematic representation of the layered structure is shown in Fig. 1(a).
Considering the device structure described above with Au as the top electrode, semitransparent and flexible solar cells can be easily realized.
The specific device structure was PET/ITO/PFN/PTB7:PC71BM/MoO3/Au/MoO3.

With the advancement of science and technology and the increase in market demand, more and more researchers and enterprises have put their eyes on the research of preparing micro-structured optical elements.
The schematic diagram of the structure is shown in Fig. 1.
This is because the increase in oligomer content leads to more cross-linked structures of the product, which enhances the effects of refraction and reflection.
Further observation, the diagonal profile of a single hexagonal structure on the surface of the optical film is shown in Fig. 6.

Specifically, the structure of borosilicate glass consists of borate-rich and silicate-rich networks.
Structure and Rheology of Borosilicate Glass in Micro-scale.
The changes in structure and properties of borosilicate glass are mainly achieved through the exchange of these two boron specifications.
However, this trend will be constrained and relaxed by the silicate domain via cooperative rearrangement (structure relaxation).

SAPO-47 is a small-pore silicoaluminophosphate-based molecular sieve with CHA structure.
In this paper, we synthesized the SAPO-n (SAPO-11, SAPO-47) crystals using the same template (DEA) as the structure-directing agent.
It is believed that the zeolite nuclei would format through structure rearrangements during the aging [16-18].
Conclusions Both pure SAPO-11 and SAPO-47 crystals have been synthesized using DEA as structure-directing agent.

The crystalline structures were studied by X-ray diffraction.
Introduction Bismuth titanate (Bi4Ti3O12) is one of the bismuth layer structured ferroelectrics with a pseudo-orthorhombic structure.
In fact, the structure and properties of thin films are affected greatly by the annealing temperature [12,13].
The effect of annealing temperature on the structure and optical properties is studied.
