This contribution summarizes recent experiments in dusty plasmas and puts their results into context. The aim is to discuss the fundamental question whether a dusty plasma can be regarded as a model system for strong coupling and whether the treatmen

The dust charge of the two species in a binary mixture of particles in a dusty plasma has been measured using the concept of configurational temperature. There, the dust charge and the respective dust charge ratio are determined from the comparison o

The change in entropy of a system that is transferred between two states at different temperatures is measured in a two-dimensional plasma crystal experiment. One- and especially two-component dust clusters are confined in the plasma sheath and heate

With the ability to trap a single particle in a dusty plasma, it becomes possible to alter the structural properties of the particle assembly or to manipulate its dynamical behavior. Here, we report on a first experiment to excite the eigenmodes of a

The dynamic evolution of the microscopic structure of solid and liquid phases of complex plasmas is studied experimentally and by means of molecular dynamics (MD) simulations. In small finite systems, the cooperative motion can be described in terms

Plasmas growing or containing nanometric dust particles are widely used and proposed in plasma technological applications for production of nano-crystals and surface deposition. Here, we give a compact review of in situ methods for the diagnostics of

An in-situ method to measure the radii of single microparticles in plasmas with high precision is presented. The particles are trapped in the plasma sheath and illuminated with laser light. Using out-of-focus imaging and polarizing optics, the angle-

Single micron-sized melamine-formaldehyde particles are levitated in the sheath of an rf-plasma and exposed to an intense laser beam, while being trapped in optical tweezers. A reversible change in the particles' properties is observed and quantitati

Towards the investigation of polydisperse complex plasmas, the generation of binary mixtures is a first and important step. In this paper, the requirements for the generation of two-dimensional binary mixtures are discussed and first experiments are
