Temporal walk-off affecting optical Kerr gating in the sub-ps time range

The temporal walk-off between pump and signal pulses in broadband optical Kerr gating was analyzed and found to be critical addressing spectral and temporal characterization in the sub-ps regime.

Quantitative SERS studies by combining LOC-SERS with the standard addition method

Here, we report on a proof-of-concept study highlighting a new approach for quantitative surface enhanced Raman spectroscopy (SERS) measurements. This has been achieved by implementing the standard addition...

Bio-nano composite for remote melting

Rapid, culture-independent, optical diagnostics of centrifugally captured bacteria from urine samples

This work presents a polymeric centrifugal microfluidic platform for the rapid and sensitive identification of bacteria directly from urine, thus eliminating timeconsuming cultivation steps. This “Lab-on-a-Disc”...

Soliton scattering as a measurement tool for weak signals

We have considered relativistic soliton dynamics governed by the sine-Gordon equation and affected by short spatial inhomogeneities of the driving force and thermal noise. Developed analytical and numerical...

Highly sensitive C-reactive protein (CRP) assay using metal-enhanced fluorescence (MEF)

Fluorescence has been extensively employed in the area of diagnostic immunoassays. A significant enhancement of fluorescence can be achieved when noble metal nanoparticles are placed in close proximity...

Energy transfer and formation of long-lived ³MLCT states in multimetallic complexes with extended highly conjugated bis-terpyridyl ligands

Multimetallic complexes with extended and highly conjugated bis-2,2’:6’,2’’-terpyridyl bridging ligands, which present building blocks for coordination polymers, are investigated with respect to...

Study of the Thermal Stability and Mechanical Characteristics of MAX Phases of Ti-Al-C(N) System and Their Solid Solutions

The DTA and TG study in air of Ti2Al(C1-xNx) and Ti3AlC2 synthesized under Ar 0.1 MPa pressure and densified in thermobaric conditions at 2 GPa, 1400 oC, for 1 h showed that the increase of the amount...

A Novel Method for Continuous Synthesis of ZnO Tetrapods

In this work we propose a novel continuous method for zinc oxide tetrapod (ZnO-T) synthesis based on the combustion of micron-sized Zn particles in an air atmosphere. A stable geometry of ZnO-T structures...

Elemental analysis-aided Raman spectroscopic studies on Chinese cloisonné wares and painted enamels from the Imperial Palace

Two kinds of enamels, including Chinese cloisonné wares from Fuwang chamber and gourd-shaped painted enamels decorations from the Forbidden City, in the Imperial Palace of China, are investigated by micro-Raman...
