While many studies have been done on triplet-triplet annihilation-based photon upconversion (TTA-UC) to produce visible light with high efficiency, the efficient TTA-UC from visible to UV light, despite its importance for a variety of solar and indoor applications, remains a challenging task. Here, we report the highest visible-to-UV TTA-UC efficiency of 20.5 % based on the discovery of an excellent UV emitter, 1,4-bis((triisopropylsilyl)ethynyl)naphthalene (TIPS-Nph). TIPS-Nph is an acceptor with desirable features of high fluorescence quantum yield and high singlet generation efficiency by TTA. TIPS-Nph has a low enough triplet energy level to be sensitized by Ir(C6)2(acac), a superior donor that does not quench UV emission. The combination of TIPS-Nph and Ir(C6)2(acac) realizes the efficient UV light production even with weak light sources such as an AM 1.5 solar simulator and room LEDs.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Visible-to-UV triplet-triplet annihilation upconversion from a thermally activated delayed fluorescence/pyrene pair in an air-saturated solution.Category: thiazole.

Despite increasing use of triplet-triplet annihilation upconversion (TTA-UC) of low-energy visible light, the generation of UV photons by TTA remains challenging because of the difficulty in finding sensitizers and acceptors with suitable energy levels. Here, we report efficient, photostable visible-to-UV TTA-UC in an air-saturated solution using a new pair with suitable energy levels: a thermally activated delayed fluorescence (TADF) mol. and pyrene. 4CzIPN, which has extremely small energy difference ΔEST (0.083 eV), was used as the TADF sensitizer to promote effective triplet energy transfer to the acceptor. When oleic acid was used as an effective singlet oxygen receptor in an air-saturated solution, the 4CzIPN/pyrene pair exhibited bright upconverted emission at 370-430 nm under 445 nm laser excitation, but no noticeable upconverted emission was observed when 4CzIPN was paired with previously reported UV-emitting acceptors [2,5-diphenyloxazole (PPO), p-terphenyl, and p-quaterphenyl]. TTA was confirmed by the quadratic dependence of the upconverted emission intensity on the 445 nm laser power d. The maximum quantum yield of the upconverted emission from the 4CzIPN/pyrene pair was 0.66%, which is considerable when compared with that of a previously reported visible-to-UV TTA-UC system with a biacetyl/PPO pair (0.58%).

Activation of UV energy bandgap semiconductors for solar fuel production using visible light as energy source is one of the most challenging tasks in the artificial photosynthesis field. Triplet-triplet annihilation (TTA) based on photon upconversion (UC) generates frequently high energy (i.e., UV) from lower energy (visible). Thus, an efficient and appropriate TTA-UC system can successfully use visible light to power a photoelectrochem. cell using TiO2, leading to photovoltages, photocurrents, and photoelectrocatalytic hydrogen production Here, for the first time, visible-to-UV TTA-UC is demonstrated to be a useful strategy for performing artificial photosynthesis processes by means of UV energy bandgap semiconductors.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,5-Diphenyloxazole( cas:92-71-7 ) is researched.Safety of 2,5-Diphenyloxazole.Zhang, Hui; Dai, Xiongxin published the article 《Preparation of polystyrene scintillation microspheres and its application in measurement of β nuclide measurement》 about this compound( cas:92-71-7 ) in Fenxi Shiyanshi. Keywords: polystyrene scintillation microsphere beta nuclide measurement. Let’s learn more about this compound (cas:92-71-7).

Polystyrene scintillation microspheres (PSm) was successfully prepared by the suspension polymerization method and the swelling method in this experiment The best synthesis proportion of PSm was obtained by studying the amount of scintillator and wave transferring agent. Using PSm to measure β nuclides with different energies, the results showed that the detection efficiency of PSm was pos. correlated with the decay energy of β nuclides. The detection efficiency of 90Sr/90Y measured by PSm was close to that of scintillation cocktail, and the detection efficiency of 14C was about 39.5%. However, the detection efficiency for low-energy β nuclides 3H was extremely low of 0.3%. In the measurement of high-salt content solutions, the measurement results of scintillation fluid were inaccurate due to the delamination after mixing. PSm can effectively solve this problem and provide a new material for liquid scintillation anal.

Author is Liu, Yilin; Pang, Yijian; Yang, Lu; Ning, Shiqi; Wang, Donghan; Wu, Zhonghua.

The presence of tetracycline is ubiquitous and has adverse effects on aquatic systems. The results showed that after 1D of tetracycline exposure, the physiol. indexes of H. dubia had no remarkable change except for proline which was significantly stimulated under 0.1 mg/L tetracycline. For T. bispinosa, (POD), polyphenol oxidase (PPO) and ascorbate peroxidase (APX) activity and protein and proline content were notably promoted under different concentrations of tetracycline, but PPO activity was significantly decreased in 50 mg/L. After 14D, tetracycline caused no harm to the growth and protein content of H. dubia, but neg. influenced lipid peroxidation product and chlorophyll content in H. dubia under high tetracycline concentrations Superoxide dismutase (SOD) and POD activity of H. dubia significantly increased at high tetracycline concentrations, while catalase (CAT) and PPO activity significantly decreased. APX activity in H. dubia increased with tetracycline concentrations at low tetracycline concentrations SOD, POD, CAT, and PPO activity of T. bispinosa were induced under different concentrations of tetracycline and no lipid peroxidation was observed APX activity in T. bispinosa was significantly inhibited at high tetracycline concentrations The results suggest that tetracycline can cause oxidative damage in H. dubia but harm the metabolism process of T. bispinosa without inducing oxidative damage. Overall, the sensitivity of T. bispinosa exposed to tetracycline exposure is higher than that of H. dubia.

Currently, gamma nuclide anal. is mainly used using inorganic scintillators or semiconductor detectors. These detectors have high resolution but there are less economical, limited in size, and low process ability than plastic scintillators. Therefore, quantum dot-based plastic scintillator was developed using the advantages of the quantum dot nanomaterial and the conventional plastic scintillator. In this study, efficient plastic scintillator was fabricated by adding CdS/ZnS based on the most widely used Cd-based nanomaterial in a polystyrene matrix. In addition, the performance of the com. plastic scintillator was compared, and it was analyzed through radiol. measurement experiments The detection efficiency of fabricated plastic scintillator was higher than com. plastic scintillator, EJ-200. It is believed that this fabricated plastic scintillator can be used as a radioactivity analyzer in the medical and nuclear facility fields.
