Air conditioning is an important part in building services world-wide in both commercial and residential buildings. With the general attempt to reduce the usage of fossil fuels and increase the usage of green solutions, the market for solar air conditioning is growing rapidly. Solar air conditioning combines solar thermal absorbers to transfer solar radiation into heat with heat-driven cooling ...

We describe a technique for surface and subsurface micromachining of glass substrates by using tightly focused femtosecond laser pulses at a wavelength of 1660 nm. A salient feature of pulsed laser micromachining is its ability to drill subsurface tunnels into glass substrates. To demonstrate a potential application of this micromachining technique, we fabricate simple microfluidic structures o...

Protein crystallization screens frequently yield salt crystals as well as protein crystals. A simple method for determining whether a crystal is composed of salt or macromolecules is suggested. A drop containing one or more crystals is transferred to a glass cover slip and the cover slip is then passed through the flame of a Bunsen burner. Macromolecule crystals are destroyed by this treatment,...

Sensitive nucleic acid based detection methods such as in situ PCR, in situ RT-PCR and PRINS have great potential in the areas of developmental biology, pathogenesis and diagnostics. However, control of evaporation from in situ reactions is critical to ensure reliable data. Self-Seal Reagent, a component added directly to the in situ reaction mixture, effectively controls evaporation during in ...

In this video, we demonstrate the technique of soft lithography with polydimethyl siloxane (PDMS) which we use to fabricate a microfluidic device for culturing neurons. Previously, a silicon wafer was patterned with the design for the neuron microfluidic device using SU-8 and photolithography to create a master mold, or what we simply refer to as a "master". Next, we pour the silicon polymer PD...
