This research aimed to evaluate the fusel oil steam reforming over Ni/carbon nanotubes-silica fiber (Ni/CNTs-SF) catalysts prepared by impregnation method with 10 wt% of Ni loading. CNTs-SF was synthesized by chemical vapor deposition (CVD) using ethanol as a source for CNTs over steam reforming. The prepared catalysts were analyzed by BET, XRD, TEM, FESEM-EDS, Raman, and TG/DTG. Ni/CNTs-SF catalyst was tested for fusel oil steam reforming and compared with Ni supported on conventional silica such as a silica fiber (SF) and a silica porous (SP) at the same loading. The results found that Ni/CNTs-SF catalyst showed better catalytic activity and stability than Ni/SF and Ni/SP. TGA profile of the catalysts after fusel oil steam reforming showed that the severe carbon deposited over Ni/SP at 64% (wt%), while at 31% was found over Ni/CNTs-SF catalyst and Ni/SF catalyst. In addition, Ni/CNTs-SF catalyst exhibited the highest hydrogen yield at 15%, and Ni/SF and Ni/SP catalysts gave a lower yield of hydrogen at 11% and 7%, respectively. © 2021

The introduction of additives with specific functional groups is an important approach to extend the operational lifetime of perovskite solar cells (PSCs). Herein, the effect of the additives of benzoic acid (0F-B), 4-fluorobenzoic acid (1F-B), and 2,3,4,5,6-pentafluorobenzoic acid (5F-B) on the performance and stability of MAPbI3-based PSCs is systematically investigated. These additives can both chelate onto lead ions and form hydrogen bond with methyl ammonium ions. These combined interactions result in an increased activation energy for nucleation of perovskite crystals, thereby, increasing crystal size, reducing defect formation, improving electronic properties, as well as reducing ion migration. As a result, PSCs added with 5F-B achieve the highest power conversion efficiency (PCE) of 20.50% with a narrow distribution compared to those PSC devices added with 1F-B (19.25 %), 0F-B (18.80 %), and pristine devices (18.53 %). Notably, 5F-B-added PSCs retain 80% of their initial PCE after ≈100-day humidity test (at 25 °C and 50% relative humidity), 30-day thermal stability test (at 85 °C in nitrogen environment), and 12-day light illumination test (under continuous simulated solar radiation). © 2024 Wiley-VCH GmbH.

This study explores the potential of physically mixing individually targeted Doxorubicin (DOX)-loaded liposomes functionalized with folic acid (FA) and trastuzumab (TRA), combined with ultrasound (US) triggering, to enhance targeted breast cancer therapy. This research focused on synthesizing, characterizing, and evaluating DOX release, cellular uptake, and cytotoxicity of FA-PEG and TRA-PEG-modified liposomes mixed at different volume fractions. Low-frequency ultrasound (LFUS) and high-frequency ultrasound (HFUS) were employed to trigger DOX release. The study demonstrated that the sonicated-physically-mixed liposomes showed superior release performance (specifically the M75 group) and increased cellular uptake (specifically the M25 group) compared to individually targeted liposomes, highlighting their combined potential in breast cancer treatment.

The muon spin rotation/relaxation/resonance (μSR) spectroscopy is widely used as a unique tool for probing magnetic properties in materials. We aim to enhance this method by incorporating imaging functionality. In this study, we conducted an experiment using a new imaging device that utilizes positron tracking from muon decays to assess the reliability of positron tracking and its positional resolution. As a result, we have demonstrated that an image depicting a hole with a diameter of 5 mm could be reconstructed. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
