Measuring Sunscreen Reflectance and White Cast Using an In Vitro Skin Tone Model

Sunscreen white cast is a visible whitening on skin caused by light scattering from sunscreen films and is one of the primary reasons consumers underapply sunscreen below the 2 mg/cm2 thickness required to achieve labeled SPF. Existing methods for quantifying white cast rely on i...

Simulating exciton transport with complex absorbing potentials

We introduce a stochastic framework based on complex absorbing potentials (CAPs) to investigate exciton transport in large molecular aggregates. Within this framework, CAPs act as non-Hermitian reservoirs and sinks, enabling an effective assessment of transport efficiency. We app...
