We present a systematic high-pressure investigation of the chlorine-functionalized two-dimensional hybrid perovskite (ClPMA)PbI, integrating high-pressure synchrotron powder X-ray diffraction (HP-PXRD), photoluminescence spectroscopy (HP-PL), and first-principles density functional theory (DFT) calculations. Under hydrostatic compression up to 6.18 (±0.

Organic structure directing agents (OSDAs), such as tetrapropylammonium (TPA) cations, serve as crucial templates for the formation of zeolite frameworks. These organic molecules interact with inorganic species, guiding the assembly of the zeolite structure. In this study, we investigate the complex interplay between boron species and TPA cations during the crystallization of [B, Al]-ZSM-5 zeolites.

The development of high-performance near-ultraviolet organic light-emitting diodes (NUV-OLEDs) remains challenging due to their intrinsic wide-bandgap characteristics. Therefore, this study fully exploits the weak electron-accepting characteristics of the PPI group, combined with its high photoluminescence quantum yield (PLQY) and excellent thermal stability. Through a precise molecular structure modulation strategy involving direct introduction of electron-donating diphenylamine groups into the side phenyl ring and systematic integration of donor/acceptor units with tailored electronic properties into the main backbone, effective control of excited-state characteristics and their spatial distribution was successfully achieved.

Heart failure is a leading cause of death worldwide, and even with current treatments, the 5-y transplant-free survival rate is only ~50 to 70%. As such, there is a need to develop new treatments for patients that improve survival and quality of life. Recently, there have been efforts to develop small molecules for heart failure that directly target components of the sarcomere, including cardiac myosin.

Objective: Intravenous tissue plasminogen activator (IV t-PA) is commonly used as bridging therapy before mechanical thrombectomy (MT) in acute ischemic stroke. However, in practice, some patients undergo MT only after IV t-PA has been fully administered. This study aimed to compare clinical and radiological outcomes of MT only versus IV t-PA followed by MT within 4.
