Vacuum electrospray deposition for face-on orientation and interface preservation in organic photovoltaics.
Sci Rep
January 2025
Department of Physics, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, Republic of Korea.
Despite recent advancements in organic photovoltaics (OPVs), further improvements in power conversion efficiency (PCE) and device lifetime are necessary for commercial viability. Strategies such as optimizing the molecular orientation and minimizing the charge traps of organic films are particularly effective in enhancing photovoltaic performance. In this study, we successfully utilized vacuum electrospray deposition (VESD) to achieve favourable face-on stacking geometries while preserving the integrity of the interfaces in poly(3-hexylthiophene-2,5-diyl) (P3HT): [6,6]-phenyl-C-butyric acid methyl ester (PCBM) bulk heterojunction (BHJ) films.

In the realm of therapeutic antibodies, co-formulations comprising two or more monoclonal antibodies (mAbs) have emerged as a promising strategy, offering enhanced treatment efficacy, improved efficiency, and prolonged intellectual property protection. These advantages have sparked significant interest among both patients and pharmaceutical companies. However, the quantification and analysis of individual mAbs within such co-formulations pose a substantial challenge due to their similar physicochemical properties.

In agricultural and waste management systems, dairy manure wastewater is often recycled for irrigation. However, a key challenge lies in handling suspended solids (SS) and effectively dewatering sludge. To address this, an innovative polycationic soybean protein-based flocculant (SPI+) was developed and applied to enhance flocculation and sludge dewatering efficiency.

Department of Metallurgy and Materials Engineering, Faculty of Engineering and Natural Sciences, Konya Technical University, Konya, Turkey.
The EuDyGeO, EuLaGeO and EuHoGeO powder were obtained through a solid-state reaction method via multistep firing of stoichiometric ratios of EuO, GeO, DyO, LaO and HoO in open atmosphere at temperatures from 800 to 1150 °C. The thermal behaviour, phase formation, SEM/EDX analysis, photoluminescence properties, Curie tempereture, dielectric and piezoelectric properties of the samples were investigated by TG/DTA, XRD, SEM, PL, TG/DTA, LCR-meter and d-meter, respectively. The germenates having triclinic crystal system have D→F, D→F, D→F, D→F transitions of Eu ions.

A universal theory for predicting the catalytic activity of hydrolytic nanozymes has yet to be developed. Herein, by investigating the polarization and hydrolysis mechanisms of nanomaterials towards amide bonds, carbocation charge was identified as a key electronic descriptor for predicting catalytic activity in amide hydrolysis. Through machine learning correlation analysis and the Sure Independence Screening and Sparsifying Operator (SISSO) algorithm, this descriptor was interpreted to associate with the d-band center and Lewis acidity on the nanomaterial surface.
