Influences of molecular structure on PUF materials’ performance were studied systematically.
Molecular structure of polyurethane (PU) varies easily by changing different soft segment or hard segment, thus greatly benefit structure design of this kind of materials.
Influence of molecular structure on performance of degradable PUFs is studied systematically.

In fig.6, we can see nano-particle inside ACS composite, which deforms an intragranular structure.
Furthermore, the intragranular-structure nano-particle can also prevent the crack.

Programmable 4D-Printed Responsive Structures Sunanta Chuayprakong*, Araya Wanamonkol and Manuschaya Khayandee Department of Industrial Chemistry, Faculty of Applied Science, King Mongkut’s University of Technology North Bangkok, Thailand *sunanta.c@sci.kmutnb.ac.th Keywords: 3D-printing, 4D-printing, Responsive structures Abstract. 4D-printing has been emerged and developed from 3D-printing.
The 4D-printing technology creates sophisticated structures in which can change over time to perform programmed functions.
In this research, simply programmable 4D-printed responsive structures were designed, prepared and studied.
The designed structures are influentially inspired by creatures and the customized 3D-printer was used.
So, all components allow a flexibility of formation of the printed tantacle inspired structures.

That means there are some microcosmic structures which can be called luminescent centers in LTO crystal, and the activation energy of these structures is close to that of Cu+ ions.
The concentration of these structures is very low, and the TL of pure LTO crystal is not sensitive.

The thermal properties, mechanical properties and structure of the composite fibers are investigated.
The WAXD measurements show that SWNTs/cellulose composite fibers are cellulose Ⅱcrystal structure.
Moreover, the structure, mechanical as well as thermal properties of the composite fibers were investigated.
It could be seen that SWNTs/cellulose composite fibers had cellulose II crystal structure.
The structure and crystallinity of SWNTs were revealed by the typical XRD pattern presented of Fig.3.

The service life of concrete structure prediction include two aspects: one is at the specified environment conditions, according to the known material durability of structure durability to design, make structure has scheduled service life; The second is according to the existing structure situation, hypothesized future structure service life.
Concrete structure service life refers to the time that the structure from start to use to structure reach the destroy limit state; Residual life is structure in the current and in not add repair or normal maintenance and normal use conditions, year of structure may continue to use.
Measures to improve the concrete durability of maritime structures Optimizing structure design Marine structure type usually has high pile beam plate structure, thin wall structure and large volume structure.
In addition, for multiple environmental chemistry，under the action of mechanical coupling of concrete durability and its life prediction research is very limited, is still does not exist reliable mathematical model.

All structures are fully optimized until residual forces are converged to smaller than 0.01 eV/Å.
All structures are appropriately re-optimized under these conditions.
On the other hand, states directly above the LUMO appear to not depend on the particular surface chemistry.
