We demonstrate microfluidic devices for terahertz spectroscopy of biomolecules in aqueous solutions. The devices are fabricated out of a plastic material that is both mechanically rigid and optically transparent with near-zero dispersion in the terahertz frequency range. Using a lowpower terahertz time-domain spectrometer, we experimentally measure the absorption spectra of the vibrational mode...

We propose a new lithography technique that combines the advantages of nanoimprint lithography (NIL) and photolithography. In this combined-nanoimprint-and-photolithography (CNP) technique, we introduce a hybrid maskmold made from UV transparent material and with a light-blocking metal layer placed on top of the mold protrusions. We demonstrate that the CNP method using such a hybrid mold can a...

The systematic review is a new category of fellowship research project. A systematic review is a complete literature review based on a clearly formatted research question. In the performance of the systematic review all relevant studies are identified, and appraised for their quality. The data from all of the selected studies are then summarized. The systematic, explicit, and transparent approa...

In addition to its fascinating electrical and mechanical properties, graphene is also an electrochemically stable and transparent electrode material. We demonstrate its applicability as both anode and cathode in a light-emitting electrochemical cell (LEC), an electrochemical analogue to a polymer organic light-emitting diode. Specifically, we summarize recent progress in carbon-based metal-free...

The fabrication of all polymer optical waveguides, based on a highly fluorescent conjugated polymer (CP) poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) and a mechanically flexible and biodegradable polymer, cellulose acetate (CA), is reported. The replication by hot embossing of patterned surfaces in CA substrates, onto which high quality F8BT films can be easily processed by spin coatin...

Highly flexible and efficient silver nanowire-based organic light-emitting diodes (OLEDs) have been successfully fabricated by employing a n-type hole injection layer (HIL). The silver nanowire-based OLEDs without light outcoupling structures exhibited excellent device characteristics such as extremely low turn-on voltage (3.6 V) and high current and power efficiencies (44.5 cd A(-1) and 35.8 l...

A simple lamination process of the top electrode for perovskite solar cells is demonstrated. The laminate electrode consists of a transparent and conductive plastic/metal mesh substrate, coated with an adhesive mixture of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), PEDOT:PSS, and sorbitol. The laminate electrode showed a high degree of transparency of 85%. Best cell performance was...

We report the discovery of transient radio emission from the nearby optically-discovered TDE ASASSN-14li (distance of 90 Mpc), making it the first typical TDE detected in the radio, and unambiguously pointing to the formation of a non-relativistic outflow with a kinetic energy of ≈ 4−10×10 erg, a velocity of ≈ 12, 000 − 36, 000 km s, and a mass of ≈ 3 × 10 − 7 × 10 M⊙. We show that the outflow ...

Pressure in oesophageal varices has been measured either by using an invasive puncture technique, or a non-invasive pneumatic pressure sensor. Experience with these techniques and their limitations prompted a new way of measuring pressure in oesophageal varices. This was done by observing through a transparent plastic balloon fixed to the tip of a gastroscope the pressure equilibrium between th...

We here proposed a new kind of ultra-compact filters based on Fano resonances on patterned single crystalline silicon nanomembranes (SiNM), which were fabricated and transferred onto transparent substrates like PET plastic and glass substrates, using a wet transfer process. The angular and polarization dependent transmission characteristics of the filter are experimentally investigated. The fil...
