Rigid, conjugated molecules are excellent candidates as molecular wires since they can achieve full extension between electrodes while maintaining conjugation. Molecular design can be used to minimize the accessible pi surface and interactions between the bridging wire and the electrode. Polyynes are archetypal molecular wires that feature a rigid molecular framework with a cross-section of a single carbon atom.

Study Objectives: Concentrated albumin early in sepsis resuscitation remains largely unexplored. Objectives were to determine 1) feasibility of early intervention with concentrated albumin in emergency department (ED) patients with suspected infection and hypoperfusion and 2) whether early albumin therapy improves outcomes.
Methods: ED patients with suspected infection and hypoperfusion (systolic blood pressure [SBP]<90 mmHg or lactate ≥4.
A Series of 40 Congenital Lung Malformation Cases and the Informative Value of CPAM Lesion Ratios.

Introduction: In this single-center retrospective analysis, we present case data and insights gathered over the past eight years. Additionally, we computed postnatal, pre-therapy lesion-to-lung ratios of Congenital Pulmonary Airway Malformations (CPAMs) to retrospectively assess potential outcome prediction using lesion-to-lung ratios.
Methods: Data were collected between 2015 and 2022.
How does goldene stack?

The recent synthesis of goldene, a 2D atomic monolayer of gold, has opened new avenues in exploring novel materials. However, the question of when multilayer goldene transitions into bulk gold remains unresolved. This study used density functional theory calculations to address this fundamental question.

Over the years, great efforts have been devoted in introducing a sizable and tunable band gap in graphene for its potential application in next-generation electronic devices. The primary challenge in modulating this gap has been the absence of a direct method for observing changes of the band gap in momentum space. In this study, advanced spatial- and angle-resolved photoemission spectroscopy technique is employed to directly visualize the gap formation in bilayer graphene, modulated by both displacement fields and moiré potentials.
