A simple, efficient and environment-friendly procedure for the synthesis of 5-arylidene rhodanines derivatives via a Knoevenagel type reaction was developed using rhodanine, variety differently substituted aldehydes Na2SO3 as benign catalyst in ethanol. Selected were subjected to basic hydrolysis afford 2-mercapto-3-substituted-acrylic acids. The presence boronic acid group is well tolerated su...

The feasibility of propagating road materials in the use of contracture wastes especially contented great amount waste bricks were researched in three aspects: Performance of recycled aggregate, mechanical properties of renewable road materials, compression splitting indexes. Conclusions are as following: recycled aggregates contenting great amount waste bricks in place of natural aggregates ar...

Tremendous increases in pesticide use in cotton growing areas have severely affected the health of peoples and degraded environment [Poswal and Williamson (1998); Ahmad and Poswal (2000); Orphal 2001 and Khan (2000)]. Farmer Field School (FFS) based IPM implemented in the world to reduce dependence on pesticides and promote environmentally safe plant protection practices. An FFS-led Integrated ...

Digital learning content is becoming more and more commonplace. However, the creation of this learning content is usually done in specialized publishing platforms, that may lock in the content. This prevents the learning content from being discovered automatically, and hinders its uptake. A more general approach for authoring discoverable learning content is needed. We built a user-friendly aut...

Environmental awareness continues to rise, and customers of all types are realizing the importance of eco-friendly products which are essential to protect our planet. Eco-designer creates designs that are demanded by markets. Green design rules are needed to support the implementation of environmental features in the practical design situation. Green design or Design for Environment (DfE) is a ...

High-purity carbon nanotubes (CNTs) are produced by chemical vapour deposition of camphor, an environment-friendly hydrocarbon. In a small CVD reactor (1-m long and 26mm wide), CVD of 3 g camphor at 650°C for 1 hour yields ~1.62 g MWNTs of diameter ~10 nm with an as-grown purity over 88%; that is, camphor-to-CNT production efficiency is 50%. This is the highest efficiency ever achieved from any...

As time-sharing machines are replaced by powerful desktop computers and farms of workstations replace mainframes, more and more users turn to workstations when they need CPU cycles for their batch jobs. Unfortunately, they do not find workstations a very friendly environment for batch processing. Since these types of machines were originally designed as a single user environment, they lack most...

Silicon nanowires (SiNWs) were fabricated by metal-assisted chemical etching (MACE) where hydrofluoric acid (HF), which is typically used in this method, was changed into ammonium fluoride (NH4F). The structure and optical properties of the obtained SiNWs were investigated in details. The length of the SiNW arrays is about 2 μm for 5 min of etching, and the mean diameter of the SiNWs is between...
