Summary: In situ ion-beam-induced luminescence measurements have shown that the emission yield of Cr3+ in electrically conductive chromium doped beta-Ga2O3 single crystals is greatly enhanced by proton irradiation. This enhancement is attributed to the pinning of the Fermi level caused by radiation defects, which activates deep carrier traps that act as sensitizers for the Cr3+ emission. In contrast, in semi-insulating samples where the Fermi level lies deep in the bandgap, the Cr3+ emission is already present in as-grown samples and no enhancement is observed upon proton irradiation. The enhancement of Cr3+ emission by irradiation in conductive samples can be reversed by thermal annealing in argon at temperatures above 550 ? for 30 s. These findings highlight the high potential of Cr-doped beta-Ga2O3 for in situ and ex situ optical radiation detection and dosimetry.

Summary: This study conducted a systematic review and meta-analysis to evaluate the effectiveness and safety of a time to isolation (TTI)-based strategy of cryoballoon ablation (CBA) in the treatment of atrial fibrillation. The results suggest that an individualized CBA dosing strategy based on TTI and extended duration of CBA can reduce recurrence post-AF ablation and decrease procedure time and incidence of phrenic nerve palsy.

Summary: This study compared the clinical outcomes of a three-dimensional electroanatomical mapping (3D-EAM)-based strategy targeting slow pathway (SP) elimination with the conventional fluoroscopic approach in atrioventricular node reentrant tachycardia (AVNRT) ablation. The results showed that 3D-EAM improved procedural parameters, reduced fluoroscopy time and dose, and increased SP elimination frequency. Follow-up results demonstrated lower recurrence rates and redo procedure rates in the 3D-EAM-based group.

Summary: By incorporating PbS quantum dots (QDs) with strong near-infrared absorption and electronic confinement into a MAPbI3 perovskite matrix, this study demonstrates the generation of sub-bandgap photocurrent, leading to solar cell efficiencies beyond classical limits. The introduction of QDs in different sizes and concentrations enhances the spectral window of photon absorption of the perovskite host film, resulting in pronounced sub-bandgap absorption and photocurrent generation below the bandgap. Despite the reduced crystallinity of the perovskite matrix, the nanostructured films exhibit significant enhancement in NIR absorption and photocurrent generation.

Summary: A new series of Zn(II) and Cu(II)-based porphyrin complexes 5a and 5b, functionalised with carbazole units, were developed as hole-transporting materials (HTMs) in perovskite solar cells (PSCs). These complexes were obtained via nucleophilic substitution reaction or using C-N transition metal-assisted coupling. The study confirmed that Zn(II) complex 5a had better alignment with the perovskite valence band level and higher potential as an HTM compared to Cu(II) complex 5b. The photovoltaic performance of the optimized complexes showed improved characteristics, with a maximum power conversion efficiency (PCE) of 10.01% for 5a. These C-N linked porphyrin derivatives demonstrate promise as novel HTMs for efficient and reproducible PSCs.

Summary: Nowadays, cryoballoon (CB) has become an established alternative to radio frequency (RF) ablation for pulmonary vein isolation (PVI), with the ability to isolate PVs in a single application. In a study on over 1000 consecutive patients, our center optimized the CB PVI procedure. It is expected that future guidelines will recommend CB as the first-line PVI for patients with paroxysmal AF and a class I indication. In a long-term follow-up of the EARLY-AF trial, CB showed a lower incidence of persistent atrial fibrillation compared to anti-arrhythmic drugs.
