Ibuprofen loading into mesoporous silica nanoparticles using Co-Spray drying: A multi-scale study

Ruffel, Lucas; Soulié, Jérémy; Coppel, Yannick; Roblin, Pierre; Brouillet, Fabien; Frances, Christine; Tourbin, Mallorie

Mesoporous Silica Nanoparticles (MSN) are used in an increasing number of applications in nanomedicine. Their synthesis and external/internal functionalization have been extensively studied as well as their biological properties. Nevertheless, the conventional drug loading processes of MSN (such as impregnation), do not enable sufficient efficiency and are difficult to consider…

Fine Multi-Phase Alignments in 2D Perovskite Solar Cells with Efficiency over 17% via Slow Post-Annealing

Wu, Guangbao; Li, Xing; Zhou, Jiyu; Zhang, Jianqi; Zhang, Xuning; Leng, Xuanye; Wang, Peijun; Chen, Ming; Zhang, Dongyang; Zhao, Kui; Liu, Shengzhong (Frank); Zhou, Huiqiong; Zhang, Yuan

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.…

Slow Magnetic Relaxation of Co(II) Single Chains Embedded within Metal–Organic Superstructures

Kawamura, Airi; Filatov, Alexander S.; Anderson, John S.; Jeon, Ie-Rang

Two coordination polymers of the type Co(BPDC)(N-ox), with BPDC being 4,4?-biphenyldicarboxylate and N-ox being pyridine N-oxide (PNO) or isoquinoline N-oxide (IQNO), have been synthesized and characterized. The compounds feature 2D and 3D metal–organic networks that encapsulate Co(II)-based chains in a rigid superstructure. The dc and ac magnetic properties of these…

Photocatalytic Template Removal by Non-Ozone-Generating UV Irradiation for the Fabrication of Well-Defined Mesoporous Inorganic Coatings

Reid, Barry; Taylor, Alaric; Alvarez-Fernandez, Alberto; Ismael, Muhamad Hafiz; Sharma, Shatakshi; Schmidt-Hansberg, Benjamin; Guldin, Stefan

The processing of mesoporous inorganic coatings typically requires a high-temperature calcination step to remove organic precursors that are essential during the material assembly. Lowering the fabrication energy costs and cutting back on the necessary resources would provide a greater scope for the deployment in applications such as architectural glass, optical…

Controlling Processing, Morphology, and Mechanical Performance in Blends of Polylactide and Thermotropic Polyesters

de Kort, Gijs W.; Rastogi, Sanjay; Wilsens, Carolus H. R. M.

Thermoplastic composites based on thermotropic liquid crystalline polymer (LCP) materials are interesting candidates for reinforced composite application due to their promising mechanical performance and potential for recyclability. In combination with a societal push toward the more sustainable use of materials, these properties warrant new interest in this class of composites.…

Tailoring vertical phase distribution of quasi-two-dimensional perovskite films via surface modification of hole-transporting layer

Liu, Tiefeng; Jiang, Youyu; Qin, Minchao; Liu, Junxue; Sun, Lulu; Qin, Fei; Hu, Lin; Xiong, Sixing; Jiang, Xueshi; Jiang, Fangyuan; Peng, Ping; Jin, Shengye; Lu, Xinhui; Zhou, Yinhua

Vertical phase distribution plays an important role in the quasi-two-dimensional perovskite solar cells. So far, the driving force and how to tailor the vertical distribution of layer numbers have been not discussed. In this work, we report that the vertical distribution of layer numbers in the quasi-two-dimensional perovskite films deposited…

Two-dimensional inverted planar perovskite solar cells with efficiency over 15% via solvent and interface engineering

Lian, Xiaomei; Chen, Jiehuan; Zhang, Yingzhu; Tian, Shuoxun; Qin, Minchao; Li, Jun; Andersen, Thomas Rieks; Wu, Gang; Lu, Xinhui; Chen, Hongzheng

High short-circuit current (Jsc) and open-circuit voltage (Voc) are both required for two-dimensional (2D) perovskite solar cells (PVSCs) with high power conversion efficiency (PCE). In this work, solvent engineering is combined with interface engineering to fabricate 2D PVSCs with enhanced Jsc and Voc. Mixing formamide with N,N-dimethylformamide (DMF) was found…

Room-Temperature Meniscus Coating of >20% Perovskite Solar Cells: A Film Formation Mechanism Investigation

Hu, Hanlin; Ren, Zhiwei; Fong, Patrick W. K.; Qin, Minchao; Liu, Danjun; Lei, Dangyuan; Lu, Xinhui; Li, Gang

Perovskite solar cells (PSCs) are ideally fabricated entirely via a scalable solution process at low temperatures to realize the promise of simple manufacturing, low-cost processing, compatibility with flexible substrates, and perovskite-based tandem solar cells. However, high-quality photoactive perovskite thin films under those processing conditions is a challenge. Here, a laminar…

3D-Printing of Pure Metal–Organic Framework Monoliths

Lim, Gwendolyn J. H.; Wu, Yue; Shah, Bhuvan B.; Koh, J. Justin; Liu, Connie K.; Zhao, Dan; Cheetham, Anthony K.; Wang, John; Ding, Jun

Metal–organic frameworks (MOFs) are usually synthesized in powder form. For many practical applications, MOFs need to be shaped into monoliths that can be easily handled. However, conventional shaping methods, such as pelletization, often result in a decrease in functionality. Recently, MOF-containing monoliths have been made using direct ink writing (DIW;…

Restricting Effect of Solvent Aggregates on Distribution and Mobility of CuCl2 in Homogenous Catalysis

Wang, Yongtao; Wang, Guanqi; Yao, Jia; Li, Haoran

Extensive experimental and theoretical studies have proven the existence of solvent aggregates in alcohols, and some attempts have been made to explore the uneven distribution of solutes. Here, we studied the distribution and mobility of CuCl2 in 3-hexanol and ethanol and investigated the aerobic oxidation of 2,3,6-trimethylphenol under these systems.…
