The synthesis and structural characterization of linear PolyC3 polymers containing trimethylene-1,1-dicarboxylate structural repeat units with C6F13 and C8F17 fluorinated side chains is described for the first time, and their properties were compared with the traditional polyvinyl structures that display the fluorinated chain on every second rather than on every third…

Physical Chemical Properties of Shea/Cocoa Butter Blends and their Potential for Chocolate Manufacture

Rodriguez-Negrette, Ana Carolina; Huck-Iriart, Cristián; Herrera, María Lidia

Cocoa butter (CB) is the preferred fat for chocolates and confections. However, for technological and economic reasons, there have been strong efforts for partially replacing it. As shea butter (SB) has become an important natural source of symmetrical stearic-rich triacylglycerols (TAG), the aim of this work was to study physical…

Tuning Pore Dimensions of Mesoporous Inorganic Films by Homopolymer Swelling

Reid, Barry; Alvarez-Fernandez, Alberto; Schmidt-Hansberg, Benjamin; Guldin, Stefan

The functionality and applications of mesoporous inorganic films are closely linked to their mesopore dimensions. For material architectures derived from a block copolymer (BCP) micelle coassembly, the pore size is typically manipulated by changing the molecular weight corresponding to the pore-forming block. However, bespoke BCP synthesis is often a costly…

Ultrathin Homogenous AuNP Monolayers as Tunable Functional Substrates for Surface-Assisted Laser Desorption/Ionization of Small Biomolecules

Liu, Zhen; Zhang, Peng; Kister, Thomas; Kraus, Tobias; Volmer, Dietrich A.

A series of ultrathin, homogenous gold nanoparticle (AuNP) substrates for surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) were prepared using a simple air/water interface approach. These SALDI substrates enabled soft ionization and provided significant improvements in terms of signal intensities and reduced background levels in comparison to other AuNP morphologies for…

Efficient Anti-solvent-free Spin-Coated and Printed Sn-Perovskite Solar Cells with Crystal-Based Precursor Solutions

He, Lintao; Gu, Hao; Liu, Xiaolong; Li, Pengwei; Dang, Yangyang; Liang, Chao; Ono, Luis K.; Qi, Yabing; Tao, Xutang

Tin-based perovskite solar cells (PSCs), with more consummate optical band gaps, lower exciton-binding energies, and higher charge-carrier mobility, have not attracted tremendous research efforts compared with the lead-based ones that have a record power conversion efficiency (PCE) of 24.2%. The major challenges for Sn-based research are significantly low open-circuit voltage,…

Regulating the phase separation of ternary organic solar cells via 3D architectured AIE molecules

Adil, Muhammad Abdullah; Zhang, Jianqi; Wang, Yuheng; Yu, Jinde; Yang, Chen; Lu, Guanghao; Wei, Zhixiang

An optimized bulk heterojunction (BHJ) interface, certifying enhanced exciton-splitting, charge separation and recombination inhibition, is vastly desired to obtain high power conversion efficiencies (PCEs). Herein, the ternary strategy has been employed to effectively modify the phase separation between the J71:ITIC blend by incorporating a 3D aggregation-induced emission (AIE) material,…

Safari, Maryam; Maiz, Jon; Shi, Guangyu; Juanes, Diana; Liu, Guoming; Wang, Dujin; Mijangos, Carmen; Alegría, Ángel; Müller, Alejandro J.

This work describes the successful melt infiltration of poly(butylene succinate) (PBS) and poly(butylene adipate) (PBA) within 70 nm diameter anodic aluminum oxide (AAO) templates. The infiltrated samples were characterized by SEM, Raman, and FTIR spectroscopy. The crystallization behaviors and crystalline structures of both polymers, bulk and confined, were analyzed by…

Layered Ruddlesden–Popper (RP) phase (2D) halide perovskites have attracted tremendous attention due to the wide tunability on their optoelectronic properties and excellent robustness in photovoltaic devices. However, charge extraction/transport and ultimate power conversion efficiency (PCE) in 2D perovskite solar cells (PSCs) are still limited by the non-eliminable quantum well effect.…

In-Depth Study of Coating Multimodal Porosity Using Ellipsometry Porosimetry in Desorption Scanning Mode

Loizillon, Jérôme; Baumgartner, Bettina; Sinturel, Christophe; Abbarchi, Marco; Lendl, Bernhard; Grosso, David

Ellipsometry porosimetry provides full adsorption/desorption isotherms and is among the most accurate techniques to probe porosity in thin films. Here we address a novel technique based on desorption scanning for a precise assessment of the porosity features revealing the size distribution of interconnections between the various populations of pores in…

Relation Between Charge Transport and the Number of Interconnected Lamellar Poly(3-Hexylthiophene) Crystals

Wang, Binghua; Chen, Jingbo; Shen, Changyu; Reiter, Günter; Zhang, Bin

We have investigated the lateral charge transport in a multilamellar network of crystalline structures of poly(3-hexylthiophene) (P3HT) embedded in a matrix of small crystallites and amorphous polymers resulting from crystallization at temperatures close to the melting point. Removing the matrix by an appropriate washing process allowed us to observe a…
