Nanosilver – Why It is Still So Hot?

Lem K.W., Haw J.R., Lee D.S., Iqbal Z., Salama A., Kurmaran S., Sund S., Curran S., Brumlik C., Choudhury A., Konkuk University, KR

At the present, we are focused on Korean consumer products because in our recent IP landscaping study, we have found that for all major patenting countries, Korea leads in nanosilver applications, with more than 1500 [...]

Role of Hard Segment Induced Nanosized Domain on Dilute Solution Properties of Ether Based Thermoplastic Polyurethanes

Lem K.W., Lee D.S., Haw J.R., Song G.S., Curran S., Sund S., Iqbal Z., Brumlik C., Konkuk University, KR

Many useful polyurethane components, such as films, are prepared from solution, in the form of dispersion, emulsion, or suspension. The ultimate properties of such films depend on the effect of nano scaled structures in the [...]

Role of Hard Segment Induced Nanosized Domain on Concentrated Solutions and Bulk Properties

Lem K.W., Lee D.S., Haw J.R., Song G.S., Curran S., Sund S., Iqbal Z., Brumlik C., Konkuk University, KR

When a film is cast from solution, the volume fraction of polymer in the film increases with increasing drying temperature and/or time. Its viscoelastic behavior transitions from more viscous (where G” > G’) in dilution [...]

Effect of Size on Properties of Nano-Structured Polymers –Transition from Macroscaling to Nanoscaling

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR

The growth in investment on the effect of size in nanoscience and nanotechnology has been astounding. Among the $12.4B spent in 2006 worldwide Nanotechnology research funding (Lux Research, 2007), at least 50%, that is >$6B, [...]

Nano Silver – Why It is so Hot Now?

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR

It has been known for centuries that silver has an antiseptic effect. In ancient times, many Greeks used silver vessels for drinking water storage. Koreans have also chosen silver to make their metal chopsticks. Recently, [...]
