Microscope lenses are typically made either by grinding and polishing glass discs, or pouring polymers into molds – both techniques can be quite involved, which is reflected in the price of the ...

Researchers have created a new type of lens that costs less than a penny to make, and can be used in a 3-D printed attachment that turns a Smartphone into a dermascope, a tool to diagnose skin ...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers have, for the ...

Initially introduced as an accessory to scanning tunneling microscopy (STM), atomic force microscopy (AFM) has become an advanced and most valuable scanning probe technique broadly used in academic ...

Overcoming silicon's intrinsically poor light emission is a crucial problem that many research groups are tackling. Graham Turnbull and Ifor Samuel describe how their simple hybrid silicon-polymer ...

Researchers from Osaka University combine high-speed atomic force microscopy with a laser light source for real-time observation of azo-polymer films Osaka, Japan – Expanding our scientific ...

Historically, polymer materials were characterized solely by their bulk properties including stiffness, elongation, gas permeability, impact and modulus. Because the bulk polymers were essentially ...
