High-Quality Thiophene-Based Two-Dimensional Perovskite Films Prepared with Dual Additives and Their Application in Solar Cells.

This study explores the optimization of (TMA)MAPbI perovskite films by regulating the film quality through the addition of MACl and MAAc additives. We found that adding MACl resulted in a film of larger grains with a power conversion efficiency (PCE) of 5.34%, while excessive MACl led to the formation of low-dimensional phases.

Comparative Analysis of Thiophene-Based Interlayer Cations for Enhanced Performance in 2D Ruddlesden-Popper Perovskite Solar Cells.

2D Ruddlesden-Popper (RP) perovskites have appeared as a promising prospective material owing to their tunable optoelectronic peculiarities and structural stability. The choice of interlayer cations greatly influences the performance of the 2D RP perovskites. In this study, through theoretical calculations and experimental investigation, we demonstrate the intrinsic and device performance differences between two perovskites based on cations of thiophenemethylamine (TMA) and thiopheneethylamine (TEA).

Bandgap lowering in mixed alloys of CsBiSbBr perovskite powders.

Lead-free metal halide perovskites have received widespread attention due to their composition of minimal hazardous components, excellent air stability, and long carrier lifetimes. However, the majority of the lead-free metal halide perovskites, such as CsBiBr, have wide bandgaps, which limits their photoelectric in solar cells and optoelectronic devices. To address this issue, attempts have been made to adjust the bandgap through material alloying.

[Research progress in strigolactones and application prospect in medicinal plants].

Strigolactones(SLs) are a class of sesquiterpenoids derived from the carotenoid biosynthesis pathway with the core carbon skeleton consisting of tricyclic lactone(ABC tricyclic ring) and α,β-unsaturated furan ring(D ring). SLs are widely distributed in higher plants and are symbiotic signals between plants and Arbuscular mycorrhiza(AM), which play key roles in the evolution of plant colonizing terrestrial habitats. As a new type of plant hormone, SLs possess such important biological functions as inhibiting shoot branching(tillers), regulating root architecture, promoting secondary growth, and improving plant stress resistance.

Apamer-based sensitive and label-free electrochemical detection of neutrophil gelatinase-associated lipocalin via recycling amplification cascades.

Sensitive and selective detection of neutrophil gelatinase-associated lipocalin (NGAL) is critical for the prediction and early diagnosis of acute renal injury. In this work, the establishment of an aptamer-based, highly sensitive and label-free method for detecting NGAL in diluted human serums via metal ion-dependent DNAzyme- and exonuclease III (Exo III)-triggered recycling signal amplification cascades is described. NGAL binds with the aptamer strands in the DNAzyme/aptamer duplexes and results in the liberation of the metal ion-dependent DNAzyme sequences to cleave the hairpin signal probes on the electrode to liberate the G-quadruplex and intermediate strands.

CRISPR/Cas12a-derived sensitive electrochemical biosensing of NF-κB p50 based on hybridization chain reaction and DNA hydrogel.

Transcription factors (TFs) are key substances in regulating the transcription, replication and expression of genes, and the detection of TFs can provide valuable information to diagnose a variety of diseases. By integrating hybridization chain reaction (HCR)-activated Cas12a enzyme with bio-responsive DNA hydrogels, we propose a dual amplification and label-free homogeneous electrochemical detection method to realize sensitive nuclear factor-kappa B p50 (NF-κB p50) detection. The presence of the target molecules protects the DNA duplex probes from digesting by exonuclease III and initiates HCR to generate long double stranded DNAs that can activate the activity of RNA-guided Cas12a enzymes.

Rationale: Malignant peripheral nerve sheath tumor (MPNST) is a rare sarcoma. Owing to the lack of specific histological criteria, immunohistochemical, and molecular diagnostic markers, several differential diagnoses must be considered. Advances in molecular testing can provide significant insights for management of rare tumor.

Ectopic expression of HaNAC1, an ATAF transcription factor from Haloxylon ammodendron, improves growth and drought tolerance in transgenic Arabidopsis.

NAC transcription factors play a pivotal role in plant growth, development and response to abiotic stress. However, their biological functions in desert trees are largely unknown. In this work, the NAC transcription factor HaNAC1 from Haloxylon ammodendron, a typical wooden plant normally grown in desert, was isolated, and its possible role in plant growth and resistance to drought stress was investigated.

Switchable fluorescence of MoS quantum dots: a multifunctional probe for sensing of chromium(VI), ascorbic acid, and alkaline phosphatase activity.

A simple strategy for modulating the fluorescence of MoS quantum dots (QDs) is described. The fluorescence of MoS QDs was firstly switched off by the addition of Cr(VI), and the quenched fluorescence was further switched on by introducing ascorbic acid (AA) into the mixture. The fluorescence quenching of MoS QDs by Cr(VI) was attributed to the fluorescence inner filter effect.

TiO2 nanorod arrays functionalized with In2S3 shell layer by a low-cost route for solar energy conversion.

We report the fabrication and characterization of a TiO(2)-In(2)S(3) core-shell nanorod array structure for application of semiconductor-sensitized solar cells. Hydrothermally synthesized TiO(2) nanorod arrays on FTO glass substrates are functionalized with a uniform In(2)S(3) shell layer by using the successive ion layer adsorption and reaction (SILAR) method. This low-cost technique promotes a uniform deposition of In(2)S(3) nanoshells on the surface of TiO(2) nanorods, thus forming an intact interface between the In(2)S(3) shell and TiO(2) core.

Single-crystalline twinned ZnO nanoleaf structure via a facile hydrothermal process.

A single-crystalline twinned ZnO nanostructure with a 2-dimensional leaf-like morphology (nanoleaves) was synthesized using a facile hydrothermal strategy. The ZnO nanoleaves had 2-fold symmetric branches, which were identified by the existence of an inversion domain boundary (IDB) along the [2110] growth direction of the ribbon-like stems with both side surfaces of the stems terminated with a chemically active Zn-(0001) plane. A proposed growth mechanism suggested that the formation of IDB and the leaf-like shape are related to the dissolution of seed particles on the substrate surfaces and an OH- shielding effect in solution, respectively.

Solution-derived 40 microm vertically aligned ZnO nanowire arrays as photoelectrodes in dye-sensitized solar cells.

Well-aligned ZnO nanowire arrays with a long length of more than 40 microm were prepared successfully by using the polyethylenimine (PEI)-assisted preheating hydrothermal method (PAPHT). Several important synthetic parameters such as PEI content, growth time, preheating time and zinc salt concentration were found to determine the growth of ultralong ZnO nanowire arrays, including length, diameter, density and alignment degree. The photoluminescence (PL) spectrum of as-grown ultralong ZnO nanowire arrays revealed a UV emission and a yellow emission, which was attributed to the absorbed hydroxyl group based on the peak shift after annealing in various atmospheres.
