Aimed to obtain a type of oil displacement with both surface activity and polymer performances, this paper based on mixing initiators at low temperatures, prepared a type of anion–nonionic surface–active polymer oil displacement agent (ANSP–1) by introducing polymerizable anion–nonionic surfmer (ANS–1), acrylamide (AM) and acrylic acid (AA). Structure of ANSP–1 was measured by FTIR. Laboratory ...

The effect of a thin α-Fe2O3 compact buffer layer (BL) on the photoelectrochemical performances of a bare α-Fe2O3 nanorods photoanode is investigated. The BL is prepared through a simple spray deposition onto a fluorine-doped tin oxide (FTO) conducting glass substrate before the growth of a α-Fe2O3 nanorods via a hydrothermal process. Insertion of the hematite BL between the FTO and the nanorod...

The direct-condensation panel was demonstrated to be effective in reducing carbon emissions of space heating for its high energy efficiency. To expand application prospects, the thermal performances Direct-Condensation Panel (DCP) with various aspect ratios are investigated and compared this paper. results show that vertical temperature gradients working area 0.1 m 1.5 1.6°C 3.3°C DCP ratio 0.4...

The effects of bonding temperatures on the composite properties and reliability performances of anisotropic conductive films (ACFs) for flip chip on organic substrates assemblies were studied. As the bonding temperature decreased, the composite properties of ACF, such as water absorption, glass transition temperature (Tg), elastic modulus (E 0) and coefficient of thermal expansion (a), were imp...

Scope of this chapter is to provide design criteria for spacecraft solar arrays at system level. The design a satellite solar array is usually influenced by several constraints; mission profile, chosen attitude, overall spacecraft configuration, mass and sizing requirements, etc. Moreover, its design has to be harmonised with the chosen solar array power conditioning, in order to optimize mass,...

The surfaces of poplar wood fibers were modified using high-temperature hot air (HTHA) treatment and silane coupling agent. The single factor test was then used to investigate the performances (e.g., the change of functional groups, polarity, cellulose crystallinity, and thermal stability) of modified poplar wood fibers (mPWF) through Fourier transform infrared spectrometry, X-ray diffraction a...

Recent years have seen an increasing public interest in issues related to energy saving and environmental pollution reduction in the building sector. As a result, many directives have been issued, the most important being the Directive 2010/31/EU (EPBD Recast) on the energy performance of buildings, which requires that “Member States shall ensure that by 31 December 2020 all new buildings are n...

In heat sinks, the flow within the core exhibits separation and hence does not lend itself to simple analytical boundary layer or duct flow analysis of the wall friction. In this paper, we present some findings from an experimental and numerical study aimed to obtain physical insight into the influence of the presence of the shield and its position on the hydraulic and thermal performance of sq...
