Design of Dual-Mode Optical Thermometry Based on Thermally Activated Efficient Energy Transfer in LaNbO/Ln (Eu/Sm/Pr) Phosphors.

Exploring methods to achieve high thermal stability in phosphors is of great significance for their applications in high-temperature fields. Currently, energy transfer (ET) from the host to activator lanthanide ions (Ln) is an effective approach to improving the antithermal quenching of phosphors. In this contribution, LaNbO (LNO) with efficient blue emission is used as the host to construct the host-Ln dual-emitting LNO/Ln (Eu/Sm/Pr) phosphor system, and the ET efficiency under thermal activation is investigated.

Achieved High-Sensitivity Single-Band Ratiometric Optical Thermometry by Manipulating the Intervalence Charge-Transfer Band Position.

Currently, optical thermometry has received widespread attention because of its noncontact and wide temperature range, but most of them are based on the application of dual-band optical ratiometric thermometry, so the development of a single-band ratiometric (SBR) optical thermometry, which is easier to analyze and use, is particularly important. In this work, the position of the intervalence charge-transfer (IVCT) band for NaGdLaTiO:Pr ( = 0, 0.5, 1.

Construction of thermally stable Tb-activated green-emitting phosphors: dual driving strategy of doping concentration and excitation wavelength.

The realization of thermally stable Tb-doped green emission at high temperatures in solid-state lighting is still a crucial challenge. Nevertheless, the study on modulating the thermally stable luminescence at high temperatures is seldom reported. The position of the intervalence charge transfer (IVCT) energy level is used to systematically investigate the thermal quenching performance of Tb-activated green-emitting phosphors with varying concentration gradients of GdTaO:Tb ( = 0.

Enhanced thermally stable performance of Pr-doped vanadate phosphor by inhibiting the intervalence charge transfer quenching channel.

Praseodymium (Pr) ion and the transition metal vanadium (V) ion with d electronic configuration can form an intervalence charge transfer (IVCT) band, which can function both as a compensatory channel for its red emission and as a quenching channel, thus affecting the luminescence thermal stability of the phosphors. Research studies reveal that the emission of Pr in the YVO matrix can be quenched by the IVCT mechanism, thereby limiting the application of phosphors. As such, the present contribution is based on the solid solution replacement strategy to inhibit the constitutent of the IVCT quenching channel and thus improve thermal stability.

Therefore, it is essential to investigate the displacement mechanism in detail. In this contribution, we created LiCaMVO:5%Sm (M = Mg/Zn) phosphors with considerably red-shifted CTB edges upon temperature stimulation and outstanding anti-thermal quenching behavior.

SIN3-HDAC complex-associated factor, a chromatin remodelling gene located in the 12p amplicon, is a potential germ cell tumour-specific oncogene.

A genetic hallmark of malignant germ cell tumours (GCTs) is isochromosome 12p, but oncogenes located in 12p that are specifically expressed in GCT have not yet been identified. SIN3-HDAC complex-associated factor (SINHCAF) is a subunit of the Sin3/histone deacetylase (HDAC) complex, and it defines a Sin3a-Hdac complex variant that is required for the self-renewal of mouse embryonic stem cells. This study demonstrated that SINHCAF is expressed in a vast majority of malignant GCTs and is rarely expressed in somatic malignancy.

Authenticated Semi-Quantum Key Distribution Protocol Based on W States.

In 2019, Wen et al. proposed authenticated semi-quantum key distribution (ASQKD) for identity and message using the teleportation of W states and GHZ-like states without pre-shared keys. However, the ASQKD protocol presents a vital issue in the teleportation of W states owing to its inappropriate design.

Lightweight mediated semi-quantum key distribution protocol with a dishonest third party based on Bell states.

The mediated semi-quantum key distribution (MSQKD) protocol is an important research issue that lets two classical participants share secret keys securely between each other with the help of a third party (TP). However, in the existing MSQKD protocols, there are two improvable issues, namely (1) the classical participants must be equipped with expensive detectors to avoid Trojan horse attacks and (2) the trustworthiness level of TP must be honest. To the best of our knowledge, none of the existing MSQKD protocols can resolve both these issues.

Impact of Soybean Nodulation Phenotypes and Nitrogen Fertilizer Levels on the Rhizosphere Bacterial Community.

The effects of nodulation properties of legumes on the rhizosphere bacterial community are still not clear. To determine the effects of nodulation phenotypes on bacterial communities in the rhizosphere of soybean plants, we performed high-throughput sequencing of the 16S rRNA gene to estimate the rhizosphere bacterial community of three soybean lines with different nodulation phenotypes grown in soil supplied with different levels of N fertilizer. The results revealed that both the soybean nodulation phenotypes and the N levels affected the rhizosphere bacteria community, but the nodulation phenotypes contributed more than the N-supply.

To improve the electrocatalytic efficiency of the cathode and provide a wider pH range in the electro-Fenton process, N-doped multi-walled carbon nanotubes (NCNTs) and ferrous ion complexed with carboxylated carbon nanotubes (CNT-COOFe) were used to fabricate the diffusion layer and catalyst layer of a membrane cathode, respectively.
