We report a Ni-catalyzed vicinal alkylarylation of unactivated alkenes in γ,δ- and δ,ε-alkenylamines with aryl halides and alkylzinc reagents. The reaction is enabled by amine coordination and can use all primary, secondary, and tertiary amines. The reaction constructs two new C(sp)-C(sp) and C(sp)-C(sp) bonds and produces δ- and ε-arylamines with C(sp)-branching at the γ- and δ-positions.

Lithium-sulfur (Li-S) all-solid-state batteries (ASSBs) hold great promise for next-generation safe, durable and energy-dense battery technology. However, solid-state sulfur conversion reactions are kinetically sluggish and primarily constrained to the restricted three-phase boundary area of sulfur, carbon and solid electrolytes, making it challenging to achieve high sulfur utilization. Here we develop and implement mixed ionic-electronic conductors (MIECs) in sulfur cathodes to replace conventional solid electrolytes and invoke conversion reactions at sulfur-MIEC interfaces in addition to traditional three-phase boundaries.

Characterizing Architectural Glazing Performance for Circadian Light.

Energy Build

February 2025

Department of Architectural Engineering, Penn State University, University Park, PA, USA, 16803.

Growing research on the non-visual impacts of light underscores the importance of architectural glazing systems in managing transmitted shortwave solar light and shaping indoor circadian light, vital for enhancing well-being. This study, conducted in two phases, evaluates the effectiveness of existing window properties in predicting their contribution to circadian lighting. Initially, a decision tree analysis assessed these properties and revealed that although traditional glazing metrics are not entirely accurate for circadian performance estimations, they can still be effective when supplemented with specific thresholds as rapid tools for selecting windows optimized for circadian health.

Article Synopsis
  • The study explored the effects of a specific enzyme (FAEA) expressed in maize that targets the apoplast, focusing on its activity during the late stages of plant senescence and after storing the plant material.
  • FAEA levels increased until the reproductive (R) stage but dropped during full leaf senescence (R+), while the enzyme remained stable even after six months of cold storage.
  • The research found that FAEA expression led to decreased cell wall components like ferulates and improved the breakdown (saccharification) of plant material by enzymes, making it easier to extract sugars at later development stages.

Racial Trauma and Black Mothers' Mental Health: Does Cognitive Flexibility Buffer the Effects of Racialized Stress?

J Racial Ethn Health Disparities

January 2025

Department of Biobehavioral Health, The Pennsylvania State University, 219 Biobehavioral Health Bldg, University Park, PA, 16802, USA.

Racialized stress disproportionately impacts Black individuals and confers increased risk for psychological distress and executive dysfunction. However, there is little evidence on psychological distress' association with cognitive flexibility (CF), an executive function theorized to be a neurocognitive resilience factor, as it is shown to reflect the ability to adapt thoughts/behaviors to changing environmental stimuli. As such, we aimed to examine the relation between racialized stress and psychological distress and the potential buffering effects of CF.

A fundamental manifestation of the nontrivial correlations of an incompressible fractional quantum Hall (FQH) state is that an electron added to it disintegrates into more elementary particles, namely fractionally-charged composite fermions (CFs). We show here that the Girvin-MacDonald-Platzman (GMP) density-wave excitation of the ν=n/(2pn±1) FQH states also splits into more elementary single CF excitons. In particular, the GMP graviton, which refers to the recently observed spin-2 neutral excitation in the vanishing wave vector limit [Liang et al.

Understanding the process of genetic adaptation in response to human-mediated ecological change will help elucidate the eco-evolutionary impacts of human activity. In the 1930s red imported fire ants (Solenopsis invicta) were accidently introduced to the Southeastern USA, where today they are both venomous predators and toxic prey to native eastern fence lizards (Sceloporus undulatus). Here, we investigate potential lizard adaptation to invasive fire ants by generating whole-genome sequences from 420 lizards across three populations: one with long exposure to fire ants, and two unexposed populations.
