Short interaction lengths limit the application of infrared absorption spectroscopy to the study monolayer thickness films. We employ periodic infrared antenna arrays to obtain 10(4)-10(5) enhancement of protein absorption signals corresponding to zepto-mo ...
A series of cationic metalla-rectangles of the general formula [(p-cymene)4Os4(OO.intrsec.OO)2(N.intrsec.N)2]4+ have been obtained in methanol from the dinuclear arene osmium precursors [(p-cymene)2Os2(OO.intrsec.OO)2Cl2] (OO.intrsec.OO = 2,5-dihydroxy-1,4 ...
Dimethylaminonitrene complexes of IMesM+ (IMes = 1,3-bis(2,4,6-trimethylphenyl)- imidazol-2-ylidene; M = Cu, Ag, Au) were prepared in the gas phase and structurally characterized by high-resolution infrared spectroscopy of the cold species, ion-molecule re ...
We calculate the transverse and the longitudinal infrared absorption spectra of the hydrated silicon surface using a first-principles approach. The absorption spectra are computed for two different configurations of water molecules dissociatively chemisorb ...
The recent phenomenal growth of the field of biotechnology has contributed to a mounting pressure to improve process efficiency and productivity and to increase the quality and safety of end-products. This demand gave rise to the discipline of on-line biop ...
In the pharmaceutical industry, batch crystallization processes at production scale are not always well understood. Several factors have a significant impact on the process of crystallization, such as the physicochemical properties (solubility curve and su ...
We report a study on the interaction of the extracellular domain of trans-membrane proteins N-cadherin and Ll with nitrilotriacetic acid (NTA)-terminated self-assembled monolayers (SAMs) grown on silver and gold surfaces. Quartz crystal microbalance (QCM) ...
Two different fluorescent single walled carbon nanotubes (SWNT) were prepd. First by a reaction of oxidized SWNT-K salt with 1,3-bis(9-anthracenylmethyl)imidazolium chloride (bamim)Cl to provide a fluorescent system SWNT-(bamim), via ion exchange and forma ...
A simple soln.: Simply dissolving three com. available dyes and two metal salts in a buffer is sufficient to create a sensor which allows the identification of dipeptides with high selectivity by using UV/Vis spectroscopy (see picture for the adaptive beha ...
We present a MEMS infrared spectrometer for selective and quantitative chemical gas analysis. infrared absorption spectroscopy can distinguish gases easily and also detect nonreactive molecules like CO2, in contrast to e.g. metal oxide gas sensors The foll ...
