Controlled Assembly of Luminescent Lanthanide
2020/10/31Complex multiscale assemblies of metal–organic frameworks are essential in the construction of large-scale optical platforms but often restricted by their bulk nature and conventional techniques. The integration of nanomaterials and 3D printing technologies allows the fabrication of multiscale functional architectures. Our study reports a unique method of controlled 3D assembly Get price

Anticounterfeiting Quick Response Code with Emission Color
Herein, we report a novel multiple anticounterfeiting encoding strategy of invisible fluorescent quick response (QR) codes with emission color as information storage unit. The strategy requires red, green, and blue (RGB) light-emitting Get price

2,4-diaminotoluene is an aminotoluene that is para-toluidine with an additional amino group at position 2. It has a role as a metabolite. It derives from a p-toluidine. 2,4-toluenediamine appears as a colorless crystalline solid. Toxic by ingestion and inhalation. Irritates skin and eyes. Get price
Multidimensional Information Encryption and Storage: When
An entire quick response (QR) code image could be seen after 30 s UV irradiation to display the correct information (Figure 3(f)). Owing to the reversibility of photoinduced isomerization, the information of color change loop such as the rainbow pattern of different colors could be read out repeatedly by choosing correct irradiating duration (Figure 3 (g)).

2016/05/01Medicine counterfeiting is a serious issue worldwide, involving potentially devastating health repercussions. Advanced anti-counterfeit technology for drugs has therefore aroused intensive interest. However, existing anti-counterfeit technologies are associated with drawbacks such as the high cost, complex fabrication process, sophisticated operation and incapability in authenticating drug Get price
Afterglow Carbon Dots: From Fundamentals to Applications
The ability of carbon dots (CDs) to emit afterglow emission in addition to fluorescence in response to UV-to-visible excitation allows them to be a new class of luminescent materials. When compared with traditional organic or inorganic afterglow materials, CDs have a set of advantages, including small size, ease of synthesis, and absence of highly toxic metal ions. In addition, high dependence Get price

2018/01/01When the zeolites are doped with lanthanide ions, the narrow absorption and emission bands resulting from lanthanide centered emission can both be used to resolve the optical response (). Emission-resolved imaging allows the three taggants to be differentiated using their unique emission spectra ( Fig. 2A ), whereas the excitation-resolved imaging differentiates them on the basis of unique Get price

2016/05/21In this contribution, we developed a smart phone recognition based upconversion fluorescent three-dimensional (3D) quick response (QR) code for tracking and anti-counterfeiting of drugs. We firstly formulated three colored inks incorporating upconversion nanoparticles with RGB (i.e., red, green and blue) emission colors. Get price

Rapid prototyping (RP) techniques allow the construction of complex and sophisticated physical models based on personal needs, and the applications of the produced objects can be greatly extended by functionalizing the raw materials (e.g., resins) with components showing electrical, optical and magnetic properties. Here, we demonstrate a simple method for the realization of a three-dimensional Get price

Multicolor luminescence and triple
The doped lanthanide emits an intense green color upon illumination with a 980 nm excitation source and a long persisting red color (612 nm) when a UV lamp at 365 nm excitation is switched off. Based on the above luminescence modes of CaTiO 3 :Pr 3+,Er 3+, a multilevel anticounterfeiting quick response code (QR code) was developed. Get price
Mazda Check Engine Light Stays On
2021/01/22Mazda check engine light will come on and stays on when the On-Board Diagnostic (OBD) system detects a malfunction with the engine, transmission, or the evaporative emission control (EVAP) system. The check engine light on a Mazda can come on for something as simple as a loose gas cap, but it can also indicate a serious engine or transmission Get price
Angular Refactoring Examples. Common patterns, tips
2020/09/22A common situation we may see in Angular apps is wrapping all of a component's elements in a single "wrapper" element. Here, we are focused on refactoring the outer div wrapper in the template. This div is accomplishing a few things: Making the component a block-level element, adding a mouse listener, and dynamically setting border-color Get price
