Characterisation and process optimisation of photosensitive acrylates for photonics applications

Applications of Graphene to Photonics

Silicon Photonics Platform for Government Applications

We review Sandia’s silicon photonics platform for government applications. Silicon photonics offers the potential for extensive size, weight, power, and cost (SWaP-c) reductions compared to existing III-V or purely electronics circuits. The Sandia fabrication facility is certified as a trusted foundry and can therefore produce devices and circuits intended for military applications. We will des...

diagnostic and developmental potentials of dynamic assessment for writing skill

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...

Application of Photosensitive Polyimide: Mask Saving Process for Buffer Coating

Issues in the LSI polyimide buffer coating process which uses photosensitive polyimide also as a mask of passivation film etching are reviewed. Change of lithography wave length from g-line to i-line causes the difficulty in the polyimide patterning. However, today's improved polymers, both ester type and ionic type, have enough ability to open 10 um windows. Dry etching condition must be adjus...

Photopolymerized multifunctional (meth)acrylates as model polymers for dental applications.

Polymer networks that can serve as model systems for dental applications were prepared by photopolymerizations of 1,1,1-trimethylolpropane triacrylate, 1,1,1-trimethylolpropane trimethacrylate, 1,1,1-trimethylolethane trimethacrylate, ethylene glycol dimethacrylate, triethylene glycol dimethacrylate, Photomer 2028 and Photomer 3015. The UV polymerizations were initiated by 2,2-dimethoxy-2-pheny...
