for 2006 IEEE 1 An Environmental Analysis of Injection Molding Extended Abstract – Green Manufacturing Processes Alexandre Thiriez and Timothy Gutowski Department of Mechanical Engineering Massachusetts Institute of Technology Rm. 35-234 77 Massachusetts Ave. Cambridge, MA 02139 Plastic components are integral parts in electrical and electronic (E&E) products. 8.5% of the plastic production is ...

We describe an inexpensive and convenient container that solves some common problems associated with storing microcentrifuge tubes in refrigerators and freezers. It is made from a plastic box that comes prepackaged with pipet tips, and we have used FISHERbrand Redi-Tip boxes Catalog No. 21-197-8H (size 200 μL) or Catalog No. 21-197-2E (size 0.5–10 μL) (Fisher Scientific, Pittsburgh, PA, USA) w...

Plastic bottle recycling has a crucial role in environmental degradation and protection. Position background should be the same to classify plastic bottles on conveyor belt. The manual detection of is time consuming leads human error. Hence, automatic classification using deep learning techniques can assist with more accurate results reduce cost. To achieve considerably good result DL model, we...

The purpose of this report is to evaluate the applicability a novel Print and Try technique in presence aberrant endodontic anatomies achieve predictable treatment with improved outcome. According guidelines, cone beam computed tomography (CBCT) recommended complex anatomies. volumes were utilized produce stereo lithographic (STL) file, from which 3D-plastic tooth model including hollow root ca...

Context Microplastics are widespread in aquatic ecosystems and commonly recorded water, sediment a broad spectrum of marine biota. Yet, the extent to which organisms ingest microplastics directly or indirectly by trophic transfer is largely unknown.Aims This study characterises microplastic abundance across intertidal sediment, biota species different levels, investigates whether biomagnificati...

Manufacturing of electronic devices via printing techniques is often considered to be an environmentally friendly approach, partially due the efficient utilization materials. Traditionally, printed components (e.g., sensors, transistors, and displays) are relying on flexible substrates based plastic materials; this especially true in display applications where, most times, a transparent carrier...

indium tin oxide (ito) thin films were deposited on glass substrates by rf sputtering using an ito ceramic target (in2o3-sno2, 90-10 wt. %). after deposition, samples were annealed at different temperatures in vacuum furnace. the post vacuum annealing effects on the structural, optical and electrical properties of ito films were investigated. polycrystalline ito films have been analyzed in wide...
