Microstructure of the weld-heat affected zone (HAZ)-base material was observed on metallographic cross-sections.
BM stands for base material and W for weld.
Moreover, there is virtually no difference between Debye ring obtained from base material and the area near weld done at 15 m/min.

Liang and Qian have synthesized the tellurium nanowires with diameter around 25 nm via a hydrothermal reaction by using Na2TeO3 and Na2S2O3 as starting materials [14].
Materials and Methods All reagents used in the experiments were of analytical grade and used as received without further purification.
The synthesized composites open up opportunities to produce nanoscale materials possessing both electronic and ionic conductivity.

Concrete mix design and test method Raw materials selection Yangtze P.O 52.5 grade cement, the initial setting time is 146min, the final setting time is 211min, the standard consistency water 27.8%.
The expansive agent amount of cementitious material content are 0%, 8%, 10% and 12%, concrete mixtures were listed in table 1.
Temperature control of SCC filled steel box concrete For the concrete pouring of this project in steel box girder, and cementitious materials dosage of self-compacting concrete is larger, considering the feature that cement hydration temperature rise will also lead to concrete self expansion, Therefore, it must strictly control the internal heat accumulation and superposition of concrete.
Construction of the reserved hole, vibration Side by casting, combined with pressure grouting technology, strict control of free shrinkage of self-compacting concrete pouring construction; by reducing the concrete casting temperature, surface covered with insulation of internal and external temperature materials and other measures to control the girder of self-compacting concrete.

Several organic UV absorbing compounds were synthesized and developed continuously from the past decade until nowadays for using in sunscreen products and UV filter materials.
The results from this work can be apply for the synthesize novel organic UV absorbing compounds to use in the composition of sunscreen products and UV filter materials which can absorb all UVA and UVB regions with high intensity.

Recently organic–inorganic nano-composites have been extensively studied since these materials exhibited the combined characteristics of organic polymer (e.g., flexibility, ductility, dielectric property) and inorganic materials (e.g., rigidity, high thermal stability, strength, hardness) [15–17].
Based on these theories it is supposed that organic–inorganic hybrid materials may be an excellent candidate for chromate-free passive films.

Introduction The oxide dispersion strengthened (ODS) steels are promising materials for applications in fission nuclear reactors of IVth generation and in fusion nuclear reactors [1,2].
Yield stress (σy) vs. temperature curves of ODS* and other materials of similar composition prepared through the conventional route.
The strengthening mechanisms have been examined: the difference between reinforced and unreinforced materials is substantially due to the Orowan stress (σK) up to 500 °C and to the Arzt-Rősler-Wilkinson stress (σARW) above 500 °C.
