Reversible pH-responsive supramolecular aggregates from viologen based amphiphiles - a molecular design perspective.

pH responsive self-assembled supramolecular systems in water hold tremendous promise spanning across the various realms of science and technology. Herein, we report the design and synthesis of benzyl viologen (BV) based amphiphiles and their ability to form pH responsive aggregates with a water soluble anionic dye (electron donor), a polyelectrolyte (PE), and a surfactant. To counter the low solubility of viologen derivatives, β-cyclodextrin (β-CD) was employed as a solubility promoter and the host-guest complexes were characterized by NMR spectroscopy.

An Assessment of Collaborations Between Centers for Independent Living and Vocational Rehabilitation Agencies Around Transition-Age Youth.

Centers for independent living (CILs) and vocational rehabilitation (VR) agencies offer transition services that many youth with disabilities could benefit from, but little is known about the existence of and potential for collaborations between these agencies. In this study, we examined data from VR agencies to assess their relationships with CILs involving transition-age youth at the national and state levels, focusing on two types of collaborations: referrals from CILs to VR agencies and VR youth's use of CIL services. Although many CILs and VR agencies do work together, their relationships vary, and these collaborations reflect only a small fraction of VR youth who are transition age.

Analysis of Lithium Aging Using Machine Learning-Enhanced Spectroscopy Techniques.

Lithium compounds such as lithium hydride (LiH) and lithium hydroxide (LiOH) have a wide range of industrial applications, but are highly reactive in environments with HO and CO. These reactions lead to the ingrowth of secondary lithium compounds, which can alter the homogeneity and affect the application of particular lithium chemicals. This study performed an exploratory analysis of different lithium compounds using laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy.

Comparative Study of Degree of Great Toe Movement after Complete and Partial Flexor Hallucis Longus Harvest in Free Fibula Flap.

 The flexor hallucis longus (FHL) muscle is crucial in fine motor control of the great toe but the muscle is often sacrificed in free fibula flap (FFF) reconstruction. The aim of this study was to compare great toe movement between complete and partial FHL resection during FFF harvest to see if FHL can be left behind (without undergoing fibrosis) in situ when bulk is not required at the recipient site.  A prospective, cross-sectional, observational study was performed including patients undergoing FFF harvest over a 2-year period.

Effect of Surface Electron Trapping and Small Polaron Formation on the Photocatalytic Efficiency of Copper(I) and Copper(II) Oxides.

CuO, CuO, and mixed phase CuO/CuO represent promising candidates for photoelectrochemical H evolution due to their strong visible light absorption, earth-abundance, and chemical stability. However, the photoelectrochemical efficiency in these materials remains far below the theoretical limit, largely due to poorly understood surface electron dynamics. These dynamics depend on defect states, such as Cu atom vacancies and phase boundaries, which control electron trapping, charge carrier separation, and recombination.

Generation of OAM beams with quasi omnidirectional pattern using simple slotted waveguide array.

Theory and design aspects of the Slotted Waveguide Antenna (SWA) array for the simultaneous generation of Orbital Angular Momentum (OAM) modes are proposed in this paper. The proposed method is a novel approach to OAM generation that uses a simple feeding scheme and has better performance, especially in terms of mode purity. Due to its all-metallic structure, the high-power OAM beams with first-order modes ( ) can be generated simultaneously along the propagation axis but in opposite directions, which improves the coverage and makes the proposed SWA be used in applications like radar target detection by mounting it on a mechanically rotating platform.
