The desire for lightweight nanoporous materials with high-performance thermal insulation and efficient anti-ablation resistance for energy conservation and thermal protection/insulation has greatly motivated research and development recently. The main challenge to synthesize such lightweight materials is how to balance the relationship of low thermal conductivity and flame retardancy. Herein, w...

Significance: The development of iron-catalyzed cross-coupling reactions is an extremely promising field of research, taken into account the importance of this method for current organic synthesis and the multiple problems connected with commonly used Pdand Ni-catalyzed processes. The group of Cahiez reported the first iron-catalyzed alkyl–aryl cross-coupling reaction, suitable for industrial l...

Mature oilfields usually encounter the problem of high watercut. It is practical to use chemical methods for water-shutoff in production wells, however conventional water-shutoff agents have problems of long gelation time, low gel strength, and poor stability under low temperature and high salinity conditions. In this work a novel polymer gel for low temperature and high salinity reservoirs was...

The ability to form ZnO nanowire arrays with dedicated morphological properties is crucial for the development of efficient piezoelectric devices such as nanogenerators and sensors. However, their integration typically requires use metallic seed layers synthesis by chemical bath deposition, from which control still very limited. In this context, formation mechanisms nanowires Au are carefully i...

Microcantilever is a device of MEMS (microelectro-mechanical system) which can be used as bio-chemical sensor, such to determine the characteristics chemical liquids. In this work, an investigation evaporation rate liquids, i.e., ethanol, methanol, and propanol, was carried out using resonant frequency change vibrated microcantilever. We two types microcantilever, namely uncoated-microcantileve...

Abstract The large-scale application of phenolic aerogel is limited by its complex and lengthy production process as well expensive cost. Herein a simultaneous drying-curing method for aerogels was designed based on the sol–gel process, series with different hexamethylenetetramine (HMTA) contents were prepared. material parameters such microstructure, pore structure, mechanical properties, shri...

In this work, zinc oxide (ZnO) nanorods structure in the form of thin film have been grown on soda-lime glass (SLG) substrate incorporating two simple steps. Firstly, ZnO seed layer was pre-deposited onto SLG by thermal evaporation method. During process, oxidation temperatures were varied range 450 oC to 650 annealed for 3 hours. Then, surface sol-gel immersion method with use nitrate hexahydr...
