Summary: Since the first surgery 50 years ago, cochlear implantation has been the major treatment for severe sensorineural hearing loss. However, foreign body reactions after surgery often lead to fibrosis and residual hearing loss. A zwitterionic coating composed of poly sulfobetaine methacrylate (PSB) and polydopamine (PDA) is developed to inhibit fibrosis and improve the outcomes of cochlear implants.

Summary: In this study, a ceramic membrane with a polydopamine (PDA) coating was successfully prepared using a high-temperature dynamic deposition method, resulting in a temperature-resistant and anti-sugar-juice fouling surface. The coating showed improved thermal and chemical stability, reduced surface roughness and negative charge compared to the raw membrane. It also exhibited good food safety and anti-fouling performance during the filtration of brown sugar redissolved syrup. The proposed high-temperature dynamic deposition method is a simple, effective, and safe approach for preparing durable anti-fouling ceramic membranes.

Summary: This study presented a precise surface modification method for water treatment membranes by grafting polymers to control the density of the modifying polymer, achieving precise control over fouling behavior of the membrane. By varying solvent types during immobilization reaction, high-density surface modification with poor solvents and low-density surface modification with good solvents were achieved, demonstrating that a membrane modified with higher molecular-weight polyMPC with a higher density was more effective for antifouling.

Summary: In this study, a cellulose-based nanofiber membrane with exceptional hydrophilicity and oleophobicity is reported, which allows the penetration of water and rejects organic solvents, avoiding fouling by organic residues. The membrane is fabricated through electrospinning of cellulose acetate and subsequent deacetylation, followed by binding with a zwitterionic copolymer. The resulting membrane exhibits highly selective penetration of the water phase from various oil/water mixtures, with high filtration efficiency and reusability.

Summary: In order to imitate the cell adhesion ability of nature, researchers often modify the surface of PCL with nature-derived polymers or functionalize it using a cell-binding motif. However, these surface modifications are limited to the surface, require multiple steps, and involve harsh conditions. In this study, a one-step strategy is proposed where thiol-ene chemistry is used to crosslink alkene-functionalized PCL with a multifunctional thiol, and a cysteine coupling site is used to covalently bind the cell-binding motif C(-linker-)RGD throughout the PCL networks during crosslinking. The influence of different linkers between the cysteine coupling site and the cell-binding motif RGD is investigated and the functionalization is evaluated using static contact angle measurements and X-ray photoelectron spectroscopy. Successful introduction of cell adhesiveness is demonstrated by seeding fibroblasts onto the functionalized PCL networks.

Summary: This study reports neutron reflectometry (NR) studies of bio-mimetic polymer polydopamine (PDA) deposited from differing initial concentrations of precursor material dopamine hydrochloride. Confocal laser scanning microscopy (CLSM) and atomic force microscopy (AFM) were performed to understand the surface structure and mechanical differences of PDA. The results show that film structure and quality are heavily impacted by the initial concentration of dopamine hydrochloride and the polymerization time, indicating the highly customizable nature of PDA.

Summary: The antifouling performance of low-pressure carbon nanotube membranes was investigated through polydopamine (PDA) biomimetic modification. The layered MWCNTs-PDA membrane showed enhanced antifouling properties compared to the blended PDA/MWCNTs membrane due to increased electronegativity and hydrophilicity. The PDA biomimetic modification combined with MWCNTs membrane exhibited superior antifouling and rejection performance in processing NOM and artificial wastewater, with a high exclusion rate of humic-like foulants and reduced bacterial attachment.

Summary: This study investigated barriers to physician use of published evidence-based guidelines in chronic myeloid leukemia (CML) management in a real-world setting. Despite the majority of physicians acknowledging the usefulness of CML guidelines, only a fraction of them actually followed the guidelines in practice. There were discrepancies between physicians' treatment preferences and actual practices, indicating a need for improvement in the details of CML management.

Summary: Researchers report a facile plasmonic approach for electrically controlled spatial modulation of exciton emissions in a WS2 monolayer. The emission routing is enabled by the resonance coupling between WS2 excitons and multipole plasmon modes in individual silver nanorods, and can be modulated by the doping level of the WS2 monolayer. This work offers great opportunities for the development of nanoscale light sources and nanophotonic devices.

Summary: In this study, the dewatering performance of commercial polyethersulfone (PES) microfiltration (MF) membranes was evaluated using an integrated experiment and modeling approach. The effects of algae concentration, testing time, feed flow rate, and chemical cleaning on the dewatering performance and fouling-layer morphology were investigated. The fouling behavior was successfully described using the Hermia and gel layer models with a gel concentration of 48 g/L for algae solutions. Furthermore, hydrophilic zwitterions were grafted onto the PES membrane surface, which mitigated fouling.

This study demonstrates that chiral cavity plasmon resonances can enhance the chiral optical response of film-coupled chiral Au helicoid nanoparticles. Furthermore, the chiral cavity mode can modulate the emission polarization of a point electric dipole, enabling the emission of circularly polarized photons. These findings provide a promising platform for advanced chiral optical devices.

Summary: Applying pressure is essential in synthesizing high-temperature superconducting hydrides. However, stabilizing the high-pressure phase of hydrides under ambient conditions is challenging. By modulating the charge transfer from metal atoms to hydrogen atoms, it is possible to maintain the dynamical stability of the hydride CaBH5 at pressures as low as 1 GPa. This new mechanism, called charge transfer modulated virtual high-pressure effect, enhances the structural stability and enables the reemergence of the forbidden [BH5](2)- anion, resulting in a strongly coupled superconductor CsBH5 with a transition temperature of 98 K.

Summary: We report an experiment that simulates the charging process of a XXZ Heisenberg Hamiltonian-driven quantum battery using single photons and linear optics. We find that entanglement is not always the most important resource for boosting charging, while coherence plays a significant role. We construct a two-qubit quantum battery and investigate the performance of quantum batteries and their relationship with the amount of entanglement and coherence during charging. Our findings offer insights for designing more efficient quantum devices and advance our understanding of quantum resources.

Summary: This paper presents a formalism for calculating response functions based on the generalized GW (GGW) method, which is applicable to electronic systems with spin-dependent interaction. The formalism automatically ensures the fluctuation-dissipation theorem (FDT) and is theoretically proven to respect the Ward-Takahashi identity (WTI). In contrast, the commonly used random phase approximation (RPA) violates both WTI and FDT within the GGW method, while the Bethe-Salpeter equation (BSE) satisfies WTI but not FDT. The validity of this formalism is demonstrated on the two-dimensional one-band Hubbard model, showing significant improvements over the RPA formula. With a computational cost similar to BSE, our formalism is expected to be applied to realistic materials.

Summary: The properties of polaritonic states and Bose-Einstein condensation in the Rabi lattice model are studied using the unitary transformation method. The study shows that the counter-rotating coupling induces an Ising-like interaction among intersite TLSs and leads to the formation of the delocalized superradiant phase.
