Novel rhodamine-based colorimetric and fluorescent sensor for the dual-channel detection of Cu and Co/trivalent metal ions and its AIRE activities.

A rhodamine hydrazone 1 bearing coumarin moiety was designed and prepared. Compound 1 exhibited high selectivity toward Co and trivalent metal ions with fluorescence enhancement in CHOH solution. However, 1 selectively responded to Al in nearly pure HO media and was further applied to monitor Al in live cells. Moreover, 1 could also act as a colorimetric probe toward Cu in either CHOH or HO solution. In addition, sensor 1 displayed aggregation-induced ratiometric emission (AIRE) activities in mixed HO/CHOH ...

Herein, we report a novel approach to achieve ultrasensitive detection of multi-analyte. This approach is concluded as "rationally introduce Aggregation-Induced Emission (AIE) into chemosensor". According to this approach, by rationally introducing self-assembly moiety, the obtained chemosensor DNS could serve as a novel AIEgen and show strong AIE in DMSO/HO (water fract...

Rheological Model and Transition Velocity Equation of a Polymer Solution in a Partial Pressure Tool.

In order to solve the problem of the low production degree of oil layers caused by an excessively large permeability difference between layers during polymer flooding, we propose partial pressure injection technology using a partial pressure tool. The partial pressure tool controls the injection pressure of a polymer solution through a throttling effect to improve the oil displacement effect in high- and low-permeability reservoirs. In order to analyze the influence of the partial pressure tool on the rheol...

Eddy Current Sensor System for Blade Tip Clearance Measurement Based on a Speed Adjustment Model.

Blade tip clearance (BTC) measurement and active clearance control (ACC) are becoming crucial technologies in aero-engine health monitoring so as to improve the efficiency and reliability as well as to ensure timely maintenance. Eddy current sensor (ECS) offers an attractive option for BTC measurement due to its robustness, whereas current approaches have not considered two issues sufficiently. One is that BTC affects the response time of a measurement loop, the other is that ECS signal decays with increasi...

Optical aptasensor based on silver nanoparticles for the colorimetric detection of adenosine.

A new and straightforward optical sensor for the colorimetric determination of adenosine (AD) in human urine samples was developed. The sensor comprised silver nanoparticles (AgNPs) as colorimetric elements and anti-AD aptamer (AP) as a recognition probe. In a solution containing AD and high concentration of NaCl, due to the unique binding of AD with AP, the aggregated metal nanomaterials dispersed in the solution, and the color intensity of the solution was changed accordingly. The absorbance of the soluti...

Investigating the minimum distance between the finger flexor tendons and distal radius during wrist and finger positions in healthy people.

A dual-mode fluorometric/colorimetric sensor for Cu detection based on hybridized carbon dots and gold-silver core-shell nanoparticles.

A fluorometric and colorimetric dual mode sensing platform based on hybridized carbon dots (Cdots) and gold-silver core-shell nanoparticles (Au@Ag NPs) has been established for the sensitive detection of trace Cu2+ ions in aqueous solution. In this system, the fluorescence of Cdots was quenched by Au@Ag NPs due to the surface plasmon-enhanced energy transfer. Due to the fact that Cu2+ could accelerate the etching process of Au@Ag NPs in the presence of thiosulfate, the fluorescence of Cdots was recovered. T...

Minimal invasive plating of distal radius fractures. A safe procedure?

Minimal invasive plate osteosynthesis (MIPO) with preservation of the pronator quadratus (PQ) muscle represents a new technique for stabilization of distal radius fractures. However, the complex anatomy of the distal radius metaphysis requires implants with features that adress all morphologic specifics of this area to avoid complications, which are still reported with this technique. It was the aim of our anatomic investigation to evaluate the feasibility of plate insertion via a minimal transverse approac...

In vitro-in vivo extrapolation and hepatic clearance dependent underprediction.

Accurately predicting the hepatic clearance of compounds using in vitro to in vivo extrapolation (IVIVE) is crucial within the pharmaceutical industry. However several groups have recently highlighted the large error in the process. While empirical or regression-based scaling factors may be used to mitigate the common underprediction, they provide unsatisfying solutions since the reasoning behind the underlying error has yet to be determined. One previously noted trend was intrinsic clearance-dependent unde...
