MIT researchers have created a type of glass that is nearly invisible. MIT News reports that the glass and the process of creating it were described in a paper published by the journal ACS Nano. The paper is titled (get ready) “Nanotextured Silica Surfaces with Robust Super-Hydrophobicity and Omnidirectional Broadband Super-Transmissivity.”

The abstract to the paper describes the structure of the glass:

Taking cues from nature, we use tapered conical nanotextures to fabricate the multifunctional surfaces; the slender conical features result in large topographic roughness whilst the axial gradient in the effective refractive index minimizes reflection through adiabatic index-matching between air and the substrate.

Right. What all this means is that the researchers (Kyoo-Chul Park, Hyungryul J. Choi, Chih-Hao Chang, Robert E. Cohen, Gareth H. McKinley, and George Barbastathis) have created a technique to manufacture a glass textured in such a way that it “virtually eliminates glare.” This means the glass is almost perfectly see-through, something that is hard to even imagine. The researchers state the glass is also anti-fogging and self-cleaning, making it perfect for windows.

All I can think is that this type of glass is going to cause problems and break noses the world-over. However, a little more thought reveals what the plan undoubtedly is. Glare is really only an issue for the screens we use daily. Unless you are reading this on an e-reader or in the dark, chances are you are contending with glare right now. Glare-free monitors and touchscreen devices just got closer, thanks to these researchers. Also, a fog-free car windshield would save a lot of time on those cold winter mornings. The researchers also mention photovoltaic solar cells as another possible application.
