清洁剂的演化～新时代天然环保清洁剂

目前由于全球五大石化合成洗剂财团对清洁剂市场全面垄断,加上石化合成洗剂利润可观,所以目前第五代天然环保清洁剂,仍只能被少数有志之士所认同使用,可喜的是目前第五代天然环保清洁剂,已有许多成功的应用范例,如:2年前在台湾搁浅的阿马迪斯号漏油污染事件,为保有台湾海域天然珊瑚的生态环境,有关当局并未使用一般常用的石化合成的化油剂,而改采第五代天然环保清洁剂直接应用在海域油污清除工作,并且成功的清除油污,同时也保存了台湾垦丁海域的生态平衡,这就是第五代天然环保清洁剂的成效。

Manufacturing a green service: engaging the TRIZ model ofinnovation

Following a number of years in incremental improvements in eco-design, it is now frequently hypothesised that step changes in environmental impact are required via the generation of innovative new products or a transition to services. The paper begins by addressing the definition of needs and functionalities as important precursors to product creation. The generation of innovative environmentally friendly solutions via TRIZ models, based on the theory of inventive problem solving by Altshuller, are assessed for their ability to systematise this approach. The principles of TRIZ, derived from the study of patents and observed trends in the evolution of technical systems, will also be explored in terms of its applicability to provide an eco-centered service solution. Four product service combinations have been outlined as a basis to establish the operational characteristics of infrastructural based services. These concepts are further illustrated via service centered scenarios including those from telecommunications, car sharing and launderette facilities

Novel Eco‐Friendly Starch Paper for Use in Flexible,Transparent, and Disposable Organic Electronics

An eco‐friendly biodegradable starch paper is introduced for use in next‐generation disposable organic electronics without the need for a planarizing layer. The starch papers are formed by starch gelatinization using a very small amount of 0.5 wt% polyvinyl alcohol (PVA), a polymer that bound to the starch, and 5 wt% of a crosslinker that bound to the PVA to improve mechanical properties. This process minimizes the additions of synthetic materials. The resultant starch paper provides a remarkable mechanical strength and stability under repeated movements. Robustness tests using various chemical solvents are conducted by immersing the starch paper for 6 h. Excellent nonpolar solvent stabilities are observed. They are important for the manufacture of organic electronics that use nonpolar solution processes. The applicability of the starch paper as a flexible substrate is tested by fabricating flexible organic transistors using pentacene, dinaphtho[2,3‐b:2′,3′‐f]thieno[3,2‐b]thiophene, and poly(dimethyl‐triarylamine) using both vacuum and solution processes. Electrically well‐behaved device performances are identified. Finally, the eco‐friendly biodegradability is verified by subjecting the starch paper to complete degradation by fungi in fishbowl water over 24 d. These developments illuminate new research areas in the field of biodegradable green electronics, enabling the development of extremely low‐cost electronics.     

Bottlenecks and strategies of green mold compounds

The mold compound protects integrated circuit (IC) devices from the environmental attacks (e.g., moisture, contaminants) for its lifetime. Driven by market pressure, environmental regulations, the electronics industry is migrating to provide environmental friendly ("green") products and systems. Two major changes associated with this migration are elimination of lead and toxic halogens from the products. Thus, the halogen-free mold compound will be a part of the "green" IC package. The migration to lead-free electronics impacts the current nongreen IC packaging technology, cost and reliability of manufacturers. This article presents the technology challenges and development trend that manufacturers and end users are facing right now with the introduction of green mold compounds.

Plugging the global power leak [appliance standby mode powerreduction]

Standby mode is a convenient but extremely wasteful feature of many electronics products. The authors describe how the GreenChip family is helping to produce a more environmentally friendly switched mode power supply. The new ICs implement an extensive set of power management functions focused on improving the efficiency of the standard flyback supply in standby mode. They achieve this by introducing three special modes of operation, referred to as burst-mode, off-mode and low-frequency mode. Use of GreenChip devices can typically reduce standby power to 2-3 W, and for a slight increase in cost this can be brought down to less than 500 mW. Along with these green features, the ICs have been designed to simplify the design task and reduce the component count, thereby addressing environmental concerns while reducing overall product costs. A new development in high-voltage IC technology based on a thin-layer silicon-on-insulator (SOI) process has been announced by Philips Semiconductors. This technology, known as EZ-HV-SOI, is expected to allow significant improvements and enhancements in the next generation of GreenChip controllers
