Epitaxial LaFeO3(LFO)-based photocells, of different thicknesses (50–200 nm) have been grown on cubic LSAT (001) [(LaAlO3)0.3(Sr2TaAlO6)0.7] single-crystal substrates, using a La2/3Sr1/3MnO3 (LSMO) bottom electrode and different top electrodes [Pt,Ba0.95La0.05SnO3 (BLSO)], to determine their photoresponse. The measured short-circuit photocurrent first increases with LFO thickness and then decreases, and it is larger or smaller, when Pt or BLSO electrodes are used, respectively.
Heyy! I'm Josep and i'm finishing my degree on Chemical Engineering. I will be working in the crystallography department as part of my Bachelor's Thesis. I really enjoy working out and doing any kind of sport basically, listening to music (classical music recently) and learning stuff about new random topics. I'm looking forward to working here and getting to know the facilities as well as all the people working around!
We report that the carborane-based metal–organic framework (MOF) mCB-MOF-1 can achieve high adsorptive selectivity for CO2:N2 mixtures. This hydrophobic MOF presenting open metal sites shows high CO2 adsorption capacity and remarkable selectivity values that are maintained even under extremely humid conditions. The comparison of mCB-MOF-1' with MOF-74(Ni) demonstrates the superior performance of the former under challenging moisture operation conditions.
In article published in Advanced Sensor Research, Anna Palau and co-workers study permalloy strips with substrate-induced uniaxial anisotropy, since they offer the possibility to produce fast in-plane magnetization reversals triggered by an out-of-plane magnetic field.

The versatile hybrid perovskite nanocrystals are one of the most promising materials for optoelectronics in virtue of their tunable bandgaps and high photoluminescence quantum yields. However, their inherent crystalline chemical structure limits the chiroptical properties achievable with the material. The production of chiral perovskites has become an active field of research for its promising applications in optics, chemistry or biology. Typically, chiral halide perovskites are obtained by the incorporation of different chiral moieties in the material. Unfortunately, these chemically modified perovskites have demonstrated moderate values of chiral photoluminescence so far.
Huge success in our Severo Ochoa School on Angle Resolved Photoemision Spectroscopy (ARPES): from fundamentals to the heart of condensed matter (ARPES 2023) organized in collaboration between the MULFOX group at ICMAB and the LOREA beamline at ALBA Synchrotron.
Magnetism in SmBaMn2O5 was investigated on a single crystal by magnetic and neutron diffraction measurements. This is an oxygen deficient perovskite with a layered ordering of Sm and Ba cations. Mn atoms are coordinated with five oxygens forming a square pyramid and they are ordered in a checkerboard pattern of expanded-compressed pyramids in the ab-plane. The neutron diffraction study revealed a ferrimagnetic ordering of Mn moments below TN=134 K. Macroscopic measurements reveal a very anisotropic behavior.
The synthesis, spectroelectrochemical and structural characteristics of highly electron-accepting diketopyrrrolopyrrole (DPP) molecules with adjoining pyridinium rings is reported, along with an assessment of their toxicity, which is apparently low. The compounds show reversible electrochemistry and in one subfamily a massive increase in molar extinction coefficient upon electrochemical reduction.

Glioblastoma multiforme (GBM) is the most common and fatal primary brain tumor, and is highly resistant to conventional radiotherapy and chemotherapy. Therefore, the development of multidrug resistance and tumor recurrence are frequent. Given the poor survival with the current treatments, new therapeutic strategies are urgently needed. Radiotherapy (RT) is a common cancer treatment modality for GBM. However, there is still a need to improve RT efficiency, while reducing the severe side effects. Radiosensitizers can enhance the killing effect on tumor cells with less side effects on healthy tissues.
The February issue of the magazine "El Pou de la Gallina" from Manresa is devoted to "Doing research abroad". The number was presented at the Casino in Manresa in a round table with Xavier Obradors, who participated in the report.
#CientífiksenJoc is a program for 5th Primary School classes, where students will design a video game about an active Catalan researcher. This year the topic of energy is discussed from various research perspectives.
The integration of organic photovoltaic (OPV) modules on greenhouses is an encouraging practice to offset the energy demands of crop growth and provide extra functionality to dedicated farmland. Nevertheless, such OPV devices must meet certain optical and stability requirements to turn net zero energy greenhouse systems a reality. Here a donor:acceptor polymer blend is optimized for its use in laminated devices while matching the optical needs of crops. Optical modeling is performed and a greenhouse figure-of-merit is introduced to benchmark the trade-off between photovoltaic performance and transparency for both chloroplasts and humans. Balanced donor:acceptor ratios result in better-performing and more thermally stable devices than acceptor-enriched counterparts.

Most of the spiral magnetoelectric multiferroics investigated in recent years are geometrically or exchange-frustrated magnets, where the presence of triangular or other frustrated spin networks produce low magnetic transition temperatures. This critically limits their potential uses. The exceptional stability of the spiral magnetic order (at TS) in the layered structure of the YBaCuFeO5 double perovskite involves a nonconventional mechanism: spiral order by disorder. The model has been theoretically developed by Scaramucci et al. [Phys. Rev. Res. 2, 013273 (2020)] after the discovery of a huge impact of cation disorder on TS [M. Morin et al., Nat. Commun. 7, 13758 (2016)].

Over the last few years, research on silica nanoparticles has rapidly increased. Particularly on mesoporous silica nanoparticles (MSNs), as nanocarriers for the treatment of various diseases because of their physicochemical properties and biocompatibility. The use of MSNs combined with therapeutic agents can provide better encapsulation and effective delivery. MSNs as nanocarriers might also be a promising tool to lower the therapeutic dosage levels and thereby to reduce undesired side effects. Researchers have explored several routes to conjugate both imaging and therapeutic agents onto MSNs, thus expanding their potential as theranostic platforms, in order to allow for the early diagnosis and treatment of diseases.
ICMAB researchers have participated in a study to create a versatile platform based on hierarchically nanostructured cell-adhesion peptides using quatsomes, which opens new possibilities for tissue engineering. The study, published in ACS Appl. Mater. Interfaces is a collaboration of three CIBER-BBN groups at ICMAB, IQAC (both CSIC) and IBEC.
Synchrotron radiation based techniques are powerful tools for battery research and allow probing a wide range of length scales, with different depth sensitivities and spatial/temporal resolutions. Operando experiments enable characterization during functioning of the cell and are thus a precious tool to elucidate the reaction mechanisms taking place. In this perspective, the current state of the art for the most relevant techniques (scattering, spectroscopy, and imaging) is discussed together with the bottlenecks to address, either specific for application in the battery field or more generic. The former includes the improvement of cell designs, multi-modal characterization and development of protocols for automated or at least semi-automated data analysis to quickly process the huge amount of data resulting from operando experiments. Given the recent evolution in these areas, accelerated progress is expected in the years to come, which should in turn foster battery performance improvements.
