Deciphering the Impact of Aromatic Linkers in Self-Assembled Monolayers on the Performance of Monolithic Perovskite/Si Tandem Photovoltaic.

Aromatic linker-constructed self-assembled monolayers (Ar-SAMs) with enlarged dipole moment can modulate the work function of indium tin oxide (ITO), thereby improving hole extraction/transport efficiency. However, the specific role of the aromatic linkers between the polycyclic head and the anchoring groups of SAMs in determining the performance of perovskite solar cells (PSCs) remains unclear. In this study, we developed a series of phenothiazine-based Ar-SAMs to investigate how different aromatic linkers could affect molecular stacking, the regulation of substrate work function, and charge carrier dynamics.

Synthesis, antimicrobial activity and application of polymers of praseodymium complexes based on pyridine nitrogen oxide.

The traditional pyridine nitrogen oxide-based antimicrobial agents are often associated with health risks due to heavy metal enrichment. To mitigate this concern, we synthesized two novel complexes, Pr(mpo)(HO) and Pr(hpo)(mpo)(HO), and integrated rare-earth salts, Hhpo (2-hydroxypyridine--oxide) and Nampo (2-mercapto-pyridine--oxide sodium salt). These complexes were characterized through infrared analysis, elemental analysis, thermogravimetric analysis, and X-ray crystallographic analysis.

Reversible single-crystal-to-single-crystal transition in Gd(III) metal-organic frameworks induced by heat and solvents with a significant magnetocaloric effect.

The design and synthesis of a Gd(III) metal-organic framework with the formula [Gd(BTDI)(DMF)] (JXUST-40, HBTDI = 5,5'-(benzo[][1,2,5]thiadiazole-4,7-diyl)diisophthalic acid) are reported hererin. Interestingly, a reversible single-crystal-to-single-crystal transition between JXUST-40 and {[Gd(BTDI)(HO)]·6HO} (JXUST-40a) was achieved under the stimulation of heat and solvents. Both JXUST-40 and JXUST-40a exhibited good stability when soaked in common solvents and aqueous solutions with pH values of 1-12.

Multistimuli-responsive multicolor solid-state luminescence tuned by NH-dependent switchable hydrogen bonds.

Revealing the stimuli-responsive mechanism is the key to the accurate design of stimuli-responsive luminescent materials. We report herein the multistimuli-responsive multicolor solid-state luminescence of a new dicopper(I) complex [{Cu(bpmtzH)}(μ-dppa)](ClO) (1), and the multistimuli-responsive mechanism is clarified by investigating its four different solvated compounds 1·2CHCOCH·2HO, 1·2DMSO·2HO, 1·4CHOH, and 1·4CHCl. It is shown that luminescence mechanochromism is associated with the breakage of the hydrogen bonds of bmptzH-NH with counter-ions such as ClO induced by grinding, while luminescence vapochromism is attributable to the breaking and forming of hydrogen bonds of dppa-NH with solvents, such as acetone, dimethylsulfoxide, and methanol, caused by heating and vapor fuming.

The therapeutic value of bifidobacteria in cardiovascular disease.

There has been an increase in cardiovascular morbidity and mortality over the past few decades, making cardiovascular disease (CVD) the leading cause of death worldwide.

Preparation of capsaicin-loaded ultrafine fiber film and its application in the treatment of oral ulcers in rats.

A drug-loaded diaphragm is an easy-to-use and effective drug delivery system that is often used to treat mouth ulcers. In this study, an ultrafine fiber film loaded with capsaicin was successfully prepared using the electrospinning technology. poly-L-lactic acid and gelatin were selected as the matrix materials to form the composite fiber, and trifluoroethanol was used as a co-solvent for poly-L-lactic acid, gelatin and capsaicin to prepare the spinning solution, which was simple to fabricate.

A highly stable chain-based Eu metal-organic framework as a turn-on and blue-shift luminescent sensor for dipicolinic acid.

The development of a rapid and selective method for the identification of dipicolinic acid (DPA), a specific biomarker in spores, is of great importance for the avoidance of anthrax infection. Herein, a chain-based Eu metal-organic framework with the formula {[Eu(BTDB)(μ-OH)(HO)]·solvents} (JXUST-38, HBTDB = (benzo[][1,2,5]thiadiazole-4,7-diyl)dibenzoic acid) was obtained using 2-fluorobenzoic acid as the pH regulator. JXUST-38 exhibits good chemical and thermal stability and can specifically recognize DPA in ,-dimethylformamide solution through luminescence enhancement and blue-shift effects with a detection limit of 0.

Mechanochromic and Selective Vapochromic Solid-State Luminescence of a Dinuclear Cuprous Complex.

The unraveling of the stimuli-responsive mechanism is crucial to the design and precise synthesis of stimuli-responsive luminescent materials. We report herein the mechanochromic and selective vapochromic solid-state luminescence properties of a new bimetallic cuprous complex [{Cu(bpmtzH)}(μ-dppm)](ClO) (), and the corresponding response mechanisms are elucidated by investigating its two different solvated polymorphs ·2CHCl () and ·2CHCl (). Green-emissive and cyan-emissive can be interconverted upon alternate exposure to CHCl and CHCl vapors, which is principally attributable to a combined alteration of both intermolecular NH···OClO hydrogen bonds and intramolecular "triazolyl/phenyl" π···π interactions induced by different solvents.

Clinical and genetic analysis of a case of late onset carbamoyl phosphate synthase I deficiency caused by CPS1 mutation and literature review.

Background: Carbamoyl phosphate synthetase I defect (CPS1D) is a rare disease with clinical case reports mainly in early neonates or adults, with few reports of first onset in late neonatal to childhood. We studied the clinical and genotypic characteristics of children with childhood onset CPS1D caused by two loci mutations (one of these is a rarely reported non-frame shift mutation) in the CPS1.

Case Presentation: We present a rare case of adolescent-onset CPS1D that had been misdiagnosed due to atypical clinical features, and further investigations revealed severe hyperammonemia (287µmol/L; reference range 11.

Purpose: The present study aimed to construct a co-loading platform encapsulating curcumin and paclitaxel at ratios of 2:1-80:1 (w/w) designated "CU-PTX-LNP" and explored the synergistic effects of CU-PTX at different composite proportions on liver cancer cells using the combination index (CI) method.

Methods: The CU lipid nanoplatform (CU-LNP) formulation was optimized via single-factor and orthogonal experiments. Various concentrations of PTX were added to the optimal formulation of CU-LNP to generate CU-PTX-LNP and the nanoplatform characterized via differential scanning calorimetry (DSC), transmission electron microscope (TEM), X-ray diffraction (XRD), zeta potential, polydispersity index (PDI), and size analyses.

The application of extracellular vesicles in colorectal cancer metastasis and drug resistance: recent advances and trends.

Colorectal cancer (CRC) has high incidence and mortality rates and is one of the most common cancers of the digestive tract worldwide. Metastasis and drug resistance are the main causes of cancer treatment failure. Studies have recently suggested extracellular vesicles (EVs) as a novel mechanism for intercellular communication.

α7 Nicotinic acetylcholine receptor: a key receptor in the cholinergic anti-inflammatory pathway exerting an antidepressant effect.

Depression is a common mental illness, which is related to monoamine neurotransmitters and the dysfunction of the cholinergic, immune, glutamatergic, and neuroendocrine systems. The hypothesis of monoamine neurotransmitters is one of the commonly recognized pathogenic mechanisms of depression; however, the drugs designed based on this hypothesis have not achieved good clinical results. A recent study demonstrated that depression and inflammation were strongly correlated, and the activation of alpha7 nicotinic acetylcholine receptor (α7 nAChR)-mediated cholinergic anti-inflammatory pathway (CAP) in the cholinergic system exhibited good therapeutic effects against depression.

Solvothermal synthesis and device fabrication of a Eu-based metal-organic framework as a turn-on and blue-shift fluorescence sensor toward Cr, Al and Ga.

A novel three-dimensional Eu-based metal-organic framework with the formula {[(CH)NH][Eu(BTDI)]·HO·DMF} (JXUST-25) was prepared by solvothermal method based on Eu and 5,5'-(benzothiadiazole-4,7-diyl)diisophthalic acid (HBTDI) with benzothiadiazole (BTD) luminescent groups. Due to the presence of Eu and organic fluorescence ligand, JXUST-25 displays turn-on and blue-shift fluorescence toward Cr, Al and Ga with limits of detection (LOD) of 0.073, 0.

Modular DNA-Origami-Based Nanoarrays Enhance Cell Binding Affinity through the "Lock-and-Key" Interaction.

Surface proteins of cells are generally recognized through receptor-ligand interactions (RLIs) in disease diagnosis, but their nonuniform spatial distribution and higher-order structure lead to low binding affinity. Constructing nanotopologies that match the spatial distribution of membrane proteins to improve the binding affinity remains a challenge. Inspired by the multiantigen recognition of immune synapses, we developed modular DNA-origami-based nanoarrays with multivalent aptamers.

Controllable Synthesis of Tb Metal-Organic Frameworks with Reversible Luminescence Sensing for Benzaldehyde Vapor.

Two novel lanthanide metal-organic frameworks (MOFs) with the formulas [Tb(bidc)(Hbidc)(HO)] () and {[Tb(bidc)(HCOO)(DMF)]·solvents} () were synthesized based on 2,1,3-benzothiadiazole-4,7-dicarboxylic acid (HBTDC) under solvothermal conditions. Interestingly, benzimidazole-4,7-dicarboxylic acid (Hbidc) was formed in situ using HBTDC as the starting material. The self-assembly process of the targeted MOFs with different topological structures can be controlled by the solvents and concentration of the reactants.
