Case Western Reserve University physicists are developing ultra-thin optical coatings that could dramatically extend the life of solar panels, as well as improve areas like data storage, or protection against counterfeiting.
Counterfeiting is a serious problem affecting a wide range of industries—from medicine to electronics, inflicting enormous economic losses, posing safety concerns and putting health at risk.
The application of photoluminescent materials in the field of information security has attracted much attention. A number of anti-counterfeiting technologies have been developed, including watermarks, 2D codes and luminescent ...
Some molecules exist in two forms, such that their structures and their mirror images are not superimposable, like our left and right hands. Called chirality, it is a property these molecules have due to their asymmetry. ...
The term meta means a concept of transcendence or surpassing, and when applied to materials, metamaterials encompass artificially engineered substances that exhibit properties not naturally found in the environment. Metasurfaces, ...
Carbon-based stimuli-responsive nanomaterials are gaining much attention due to their versatility, including disease diagnosis and treatment. They work under endogenous (pH, temperature, enzyme, and redox) or exogenous (temperature, ...
Organic materials with room-temperature phosphorescence (RTP) emission have attracted extensive attention due to extraordinary properties including long lifetime, large Stokes shift, stimuli-responsiveness, and so on, and ...
Each year, an estimated two trillion dollars is lost globally due to counterfeit products ranging from jewelry to medicine. As current security labels and product authentication methods are rapidly becoming obsolete or easy ...
There are many sputtered metal film heaters on the market, but they are opaque and can only be used on the back of an anti-counterfeiting label. In addition, the heating rate is slow and the bending resistance is usually ...
A team of researchers at NYU Abu Dhabi has developed a single-step, organic solvent-free, hydrothermal process to convert polyethylene-based plastic bags and polypropylene-based surgical masks into carbon dots.
