The authors regret that the selected Figure 2A, depicting cell sheets and spheroids, was previously published in Stem Cell Research & Therapy (2022;13:276. https://***/10.1186/s13287-022-02948-3). This duplication was an unintentional oversight, as the image was included solely for illustrative purposes and does not contribute to any quantitative analysis. We sincerely apologize for this mistake and propose the following corrections: 1. Replacing Figure 2A with a new image as below that does not overlap with our previously published work.2. Including a correction statement clarifying that the image serves only an illustrative function and does not affect the study's quantitative ***, we have identified an error in Section 3.3 of the text, where "SEM" should be corrected to "TEM." We appreciate your consideration of these revisions and apologize for any confusion caused. The authors would like to apologize for any inconvenience caused. Your sincerely, Jiashing Yu and Nai-Chen Cheng Fixed Figure 2A[Figure presented] © 2025 The Author(s)

Erbium (Er) complexes are used as optical gain material for signal generation in the telecom C-band at 1540 nm, but they need a sensitizer to enhance absorption. Na+ substitution at Ag+ and Bi3+ doping at the In3+ site are possible strategies to enhance broadband emission in Cs2AgInCl6, which could be used as sensitizers to energy transfer into rare-earth elements. Herein, self-trapped exciton (STE) energy transfer to Er3+ at 1540 nm for low loss optical telecommunication applications is reported. An acid precipitation method is used to synthesize Cs2AgInCl6 and its derivative with Er3+, Bi3+, and Na+. Bare Cs2AgInCl6:Er emission signals are found to be weak at 1540 nm, but Bi3+ doping increased by 12 times, and Bi3+ and Na+ doping increased by up to 25 times signal intensity. Electron paramagnetic resonance spectroscopy characterized a decrease in axial symmetry over the Er3+ ion after substitutions of Na+ and Bi3+ in Cs2AgInCl6 at low temperature ( © 2022, The Authors.

To develop low-power, non-volatile computing-in-memory device using ferroelectric transistor technologies, ferroelectric channel materials with scaled thicknesses are required. Two-dimensional semiconductors, such as molybdenum disulfide (MoS2), equipped with sliding ferroelectricity could provide an answer. However, achieving switchable electric polarization in epitaxial MoS2 remains challenging due to the absence of mobile domain boundaries. Here we show that polarity-switchable epitaxial rhombohedral-stacked (3R) MoS2 can be used as a ferroelectric channel in ferroelectric memory transistors. We show that a shear transformation can spontaneously occur in 3R MoS2 epilayers, producing heterostructures with stable ferroelectric domains embedded in a highly dislocated and unstable non-ferroelectric matrix. This diffusionless phase transformation process produces mobile screw dislocations that enable collective polarity control of 3R MoS2 via an electric field. Polarization–electric-field measurements reveal a switching field of 0.036 V nm−1 for shear-transformed 3R MoS2. Our sliding ferroelectric transistors are non-volatile memory units with thicknesses of only two atomic layers and exhibit an average memory window of 7 V with an applied voltage of 10 V, retention times greater than 104 seconds and endurance greater than 104 cycles. © 2023, The Author(s), under exclusive licence to Springer Nature Limited.

The performance of superconducting qubits is often limited by dissipation and two-level systems (TLS) losses. The dominant sources of these losses are believed to originate from amorphous materials and defects at interfaces and surfaces, likely as a result of fabrication processes or ambient exposure. Here, we explore a novel wet chemical surface treatment at the Josephson junction-substrate and the substrate-air interfaces by replacing a buffered oxide etch (BOE) cleaning process with one that uses hydrofluoric acid followed by aqueous ammonium fluoride. We show that the ammonium fluoride etch process results in a statistically significant improvement in median T1 by ∼ 22% (p = 0.002), and a reduction in the number of strongly-coupled TLS in the tunable frequency range. Microwave resonator measurements on samples treated with the ammonium fluoride etch prior to niobium deposition also show ∼ 33% lower TLS-induced loss tangent compared to the BOE treated samples. As the chemical treatment primarily modifies the Josephson junction-substrate interface and substrate-air interface, we perform targeted chemical and structural characterizations to examine materials’ differences at these interfaces and identify multiple microscopic changes that could contribute to decreased TLS. © 2024, CC BY-NC-ND.

Polar state memory in active fluids

Spontaneous emergence of correlated states such as flocks and vortices are prime examples of remarkable collective dynamics and self-organization observed in active matter [1–6]. The formation of globally correlated polar states in geometrically confined systems proceeds through the emergence of a macroscopic steadily rotating vortex that spontaneously selects a clockwise or counterclockwise global chiral state [7, 8]. Here, we reveal that a global vortex formed by colloidal rollers exhibits state memory. The information remains stored even when the energy injection is ceased and the activity is terminated. We show that a subsequent formation of the collective states upon re-energizing the system is not random. We combine experiments and simulations to elucidate how a combination of hydrodynamic and electrostatic interactions leads to hidden asymmetries in the local particle positional order encoding the chiral state of the system. The stored information can be accessed and exploited to systematically command subsequent polar states of active liquid through temporal control of the activity. With the chirality of the emergent collective states controlled on-demand, active liquids offer new possibilities for flow manipulation, transport, and mixing at the microscale.

The most promising method for synthesizing high-quality, large-scale graphene films involves chemical vapor deposition (CVD) of carbon-containing precursors onto Cu substrates. During graphene growth in a CVD system, the interaction between graphene and the Cu substrate leads to the formation of anisotropic Cu step bunches, driven by interfacial surface energy minimization and the release of compressive stress during thermal cooling. It is widely acknowledged that a smooth substrate is crucial for achieving high-quality graphene, as graphene strain and Cu surface roughening induce wrinkles when transferred onto a silicon wafer, which negatively impacts the quality. Here, we introduce a straightforward approach for controlling strain in graphene by engineering the Cu surface morphology through mechanical tension during the growth process. We achieve a uniform distribution of low compressive strain across the graphene layer by applying varying mechanical weights to the Cu foil. Using atomic force microscopy (AFM), scanning electron microscopy (SEM), and Raman spectroscopy, we demonstrate that mechanical tension significantly reduces Cu surface roughness, providing a smoother interface for graphene growth. This work provides insights into the relationship between Cu surface structure and graphene strain, contributing to the optimization of substrate preparation for graphene synthesis and other related surface engineering applications.
