The prolonged duration of orthodontic treatment remains a significant concern for both orthodontists and patients. In this study, we developed a degradable microneedle (MN) patch composed of hyaluronic acid (HA) and sodium alginate (SA) for the delivery of receptor activator of nuclear factor-kappa B ligand (RANKL) to accelerate tooth movement. This MN patch that was crosslinked by calcium chloride (CaCl) exhibited adequate mechanical properties and favorable in vitro mucosal insertion ability.

  • 2D Ruddlesden-Popper perovskites (RPPs) are gaining popularity for their environmental stability, but their power conversion efficiency (PCE) remains lower than traditional 3D perovskite solar cells due to issues with carrier transport and phase heterogeneity.
  • The introduction of binary spacers like n-butylammonium and benzamidine helps improve the crystallization process, leading to more uniform phase distribution and enhanced carrier transport in RPP films.
  • The research achieved a record high PCE of 21.15% and an open circuit voltage of 1.26 V for low n-value RPP solar cells by using these spacers and high-quality single crystal structures, which also reduced

Deep-level traps at the buried interface of perovskite and energy mismatch problems between the perovskite layer and heterogeneous interfaces restrict the development of ideal homogenized films and efficient perovskite solar cells (PSCs) using the one-step spin-coating method. Here, we strategically employed sparingly soluble germanium iodide as a homogenized bulk in-situ reconstruction inducing material preferentially aggregated at the perovskite buried interface with gradient doping, markedly reducing deep-level traps and withstanding local lattice strain, while minimizing non-radiative recombination losses and enhancing the charge carrier lifetime over 9 µs. Furthermore, this gradient doping assisted in modifying the band diagram at the buried interface into a desirable flattened alignment, substantially mitigating the energy loss of charge carriers within perovskite films and improving the carrier extraction equilibrium.

Article Synopsis
  • Two-terminal (2T) perovskite-based tandem solar cells (TSCs) aim to exceed the efficiency limits of single-junction solar cells by using subcells with varying bandgaps, but their current highest efficiency of 33.9% is still below the theoretical maximum of 42-43%.
  • A major challenge for enhancing the effectiveness of these TSCs is the design of transparent recombination layers (RLs) that must manage optical losses, contact resistance, and other performance criteria between the subcells.
  • The review discusses the role and requirements of RLs, highlights characterization methods for research, and identifies key factors hindering RL performance improvements along with potential future research directions.

The development of static hydrogels as an optimal choice for bone tissue engineering (BTE) remains a difficult challenge primarily due to the intricate nature of bone healing processes, continuous physiological functions, and pathological changes. Hence, there is an urgent need to exploit smart hydrogels with programmable properties that can effectively enhance bone regeneration. Increasing evidence suggests that photoresponsive hydrogels are promising bioscaffolds for BTE due to their advantages such as controlled drug release, cell fate modulation, and the photothermal effect.

Wide bandgap (WBG) perovskite can construct tandem cells with narrow bandgap solar cells by adjusting the band gap to overcome the Shockley-Queisser limitation of single junction perovskite solar cells (PSCs). However, WBG perovskites still suffer from severe nonradiative carrier recombination and large open-circuit voltage loss. Here, this work uses an in situ photoluminescence (PL) measurement to monitor the intermediate phase evolution and crystallization process via blade coating.

Despite their excellent environmental stability, low defect density, and high carrier mobility, large-n quasi-two-dimensional halide perovskites (quasi-2DHPs) feature a limited application scope because of the formation of self-assembled multiple quantum wells (QWs) due to the similar thermal stabilities of large-n phases. However, large-n quasi-phase-pure 2DHPs (quasi-PP-2DHPs) can solve this problem perfectly. This review discusses the structures, formation mechanisms, and photoelectronic and physical properties of quasi-PP-2DHPs, summarises the corresponding single crystals, thin films, and heterojunction preparation methods, and presents the related advances.

Jet quenching has long been regarded as one of the key signatures for the formation of quark-gluon plasma in heavy-ion collisions. Despite significant efforts, the separate identification of quark and gluon jet quenching has remained as a challenge. Here we show that J/ψ in high transverse momentum (p) region provides a uniquely sensitive probe of in-medium gluon energy loss since its production at high p is particularly dominated by gluon fragmentation.
