Article Abstract
Antireflective transparent materials are essential for a myriad of applications to allow for clear vision and efficient light transmission. Despite the advances, efficient and low cost solutions to clean antireflective surfaces have remained elusive. Here, we present a practical approach that enables the production of antireflective polymer surfaces based on moth-eye inspired features incorporating photoinduced self-cleaning properties and enhanced mechanical resistance. The methodology involves the fabrication of sub-wavelength moth-eye nanofeatures onto transparent surface composite films in a combined processing step of nanoparticle coating and surface nanoimprinting. The resulting surfaces reduced the optical reflection losses from values of 9% of typical PMMA plastic films to an optimum value of 0.6% in the case of double-sided moth-eye nanoimprinted films. The composite moth-eye topography also showed an improved stiffness and scratch resistance. This technology represents a significant advancement not limited by scale, for the development of antireflective films for low cost application products.

With the increasing global focus on sustainable materials, paper is favored for its biodegradability and low cost. Their integration with triboelectric nanogenerators (TENGs) establishes broad prospects for self-powered, paper-based triboelectric materials. However, these materials inherently lack efficient charge storage structures, leading to rapid charge dissipation.

Spherical nucleic acids (SNAs) consist of DNA strands arranged radially and packed densely on the surface of nanoparticles. Due to their unique properties, which are not found in naturally occurring linear or circular DNA, SNAs have gained widespread attention in fields such as sensing, nanomedicine, and colloidal assembly. The rapidly evolving applications of SNAs have driven a modernization of their syntheses to meet different needs.

Importance: Commercial prices for hospital care are high and vary widely in the US. Employers and state policymakers are exploring reference-based pricing (RBP) to set their payment rates as multiples of Medicare prices; understanding the range of commercial price variation within a hospital is important for calculating the appropriate price targets that are effectively low to generate savings but also feasible and viable to local hospital markets.
Objective: To examine within-hospital maximum-to-minimum commercial hospital price gaps negotiated by 5 national insurers and estimate plan savings if the minimum prices within each hospital are used as new payment level.
Efficient Direct Air Capture in Industrial Cooling Towers Mediated by Electrochemical CO2 Release.

Direct air capture (DAC) is a promising technology for mitigating global climate change but suffers from low efficiency, small scale, and high cost due to the dilute atmospheric CO2, limited size of air contactors, and heat-driven CO2 release. Here, we propose combining DAC with widely used industrial cooling towers to extract CO2 from the air and using electrolysis to release the captured CO2 at room temperature. We first prepare a buffered absorbent solution consisting of sodium glycinate, glycine, and sodium chloride for effective CO2 capture from the air, solving the incompatibility problem of the cooling towers with conventional absorbents.

Two platinide plumbides, EuPtPb and SrPtPb, were discovered using high-temperature exploratory synthesis and flux-assisted crystal growth. Their crystal structures were determined from single-crystal X-ray diffraction. Both compounds crystallize in the orthorhombic system; EuPtPb belongs to the YRhSn structure type (2, = 4.
