iTRAQ proteomic analysis of the anterior insula in morphine-induced conditioned place preference rats with high-frequency deep brain stimulation intervention.

Morphine dependence or addiction is a serious global public health and social problem, and traditional treatments are very limited. Deep brain stimulation (DBS) has emerged as a new potential treatment for drug addiction. Repeated use of morphine leads to neuroadaptive and molecular changes in the addiction-related brain regions.

Converting Fe-N-C single-atom catalyst to a new FeNxSey cluster catalyst for proton-exchange membrane fuel cells.

Fe-N-C catalyst is the most promising alternative to platinum catalyst for proton-exchange membrane fuel cells (PEMFCs), however its high performance cannot be maintained for a long enough time in device. The construction of a new Fe coordination environment that is different from the square-planar Fe-N 4 configuration in Fe-N-C catalyst is expected to break current stability limits, which however remains unexplored. Here, we report the conversion of Fe-N-C to a new FeNxSey catalyst, where the Fe sites are three-dimensionally (3D) co-coordinated by N and Se atoms.

Molecular Orbital Tuning of Pentacene-Based Organic Semiconductors through -Ethynylation of Dihydrodiazapentacene.

This study explores the concept of molecular orbital tuning for organic semiconductors through the use of '-diethynylated derivatives of 6,13-dihydro-6,13-diazapentacene ( and ). These novel molecules maintain the same molecular geometry and π-π stacking as their parent pentacene derivatives ( and ), as confirmed by X-ray crystallography. However, they exhibit altered frontier molecular orbitals in terms of the phase, nodal properties, and energy levels.

Exceptional CO2 Hydrogenation to Ethanol via Precise Single-Atom Ir Deposition on Functional P Islands.

The thermocatalytic hydrogenation of CO2 to ethanol has attracted significant interest because ethanol offers ease of transport and substantial value in chemical synthesis. Here, we present a state-of-the-art catalyst for the CO2 hydrogenation to ethanol achieved by precisely depositing single-atom Ir species on P cluster islands situated on the In2O3 nanosheets. The Ir1-Px/In2O3 catalyst achieves an impressive ethanol yield of 3.

Highly efficient green phosphor CaLa(PO)O:Eu,Tb for white LEDs.

Although the green light emission of Tb ions can be effectively improved by utilizing energy transfer from Eu to Tb ions, obtaining phosphors with high quantum efficiency remains a major problem. Here, we have achieved a novel apatite-type structure CaLa(PO)O (CLPO) containing Eu and Tb ions. The CLPO:Eu is capable of being effectively excited by near-ultraviolet light and emits blue light at about 460 nm.

Super Strong Bonding at the interface between ETL and Perovskite for Robust Flexible Optoelectronic Devices.

Organic-inorganic hybrid perovskites have demonstrated great potential for flexible optoelectronic devices due to their superior optoelectronic properties and structural flexibility. However, mechanical deformation-induced cracks at the buried interface and delamination from the substrate severely constrain the optoelectronic performance and device lifespan. Here, we design a two-site bonding strategy aiming to reinforce the mechanical stability of the SnO2/perovskite interface and perovskite layer using a multifunctional organic salt, 4-(trifluoromethoxy)phenylhydrazine hydrochloride (TPH).

Cell proliferation suppressor RBR1 interacts with ARID1 to promote pollen mitosis via stabilizing DUO1 in Arabidopsis.

In plants, sperm cell formation involves two rounds of pollen mitoses, in which the microspore initiates the first pollen mitosis (PMI) to produce a vegetative cell and a generative cell, then the generative cell continues the second mitosis (PMII) to produce two sperm cells. DUO1, a R2R3 Myb transcription factor, is activated in the generative cell to promote S-G2/M transition during PMII. Loss-of-function of DUO1 caused a complete arrest of PMII.

Time-dependent diffusion magnetic resonance imaging for the analysis of parotid gland tumors.

Background: Different parotid tumors differ in terms of treatment strategies due to their distinct biological behaviors.

Molecular evidence for the role of the ovipositor of the fall armyworm: Where to lay or not to lay?

Oviposition behavior in insects has received considerable attention, but studies have mainly focused on the antennae, neglecting the role of the ovipositor. In this study, we investigated the functional characteristics of the ovipositor in oviposition site selection by the fall armyworm (FAW) Spodoptera frugiperda, a destructive invasive pest of maize and other cereals. In oviposition choice assays females exhibited significant repellency to isothiocyanate (ITC), volatiles specific to non-preferred cruciferous plants.

Radical Brook rearrangement: past, present, and future.

The Brook rearrangement has emerged as one of the most pivotal transformations in organic chemistry, with broad applications spanning organic synthesis, drug design, and materials science. Since its discovery in the 1950s, the anion-mediated Brook rearrangement has been extensively studied, laying the groundwork for the development of numerous innovative reactions. In contrast, the radical Brook rearrangement has garnered comparatively less attention, primarily due to the challenges associated with the controlled generation of alkoxyl radicals under mild conditions.

Point-of-care testing of methotrexate using a controlled release sensor based on a personal glucose meter.

Methotrexate (MTX), a widely administered medication for treating an array of tumors and autoimmune disorders, necessitates stringent monitoring due to the potential for severe adverse effects associated with its high dosage. Nevertheless, the existing methods for monitoring MTX are often intricate, time-consuming and incur significant costs. In this work, we constructed a controlled release sensor, harnessing the versatility of a personal glucose meter (PGM), which had been devised for the swift detection of MTX.
