Geometric inverse problems on gas giants

On gas giant planets the speed of sound is isotropic and goes to zero at the surface. Geometrically, this corresponds to a Riemannian manifold whose metric tensor has a conformal blow-up near the boundary. The blow-up is tamer than in asymptotically hyperbolic geometry: the boundary is at a finite distance.

The Origin of Improved Performance in Boron‐Alloyed Silicon Nanoparticle‐Based Anodes for Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon‐boron alloy nanoparticles are incorporated into lithium‐ion batteries as the active anode material and enhance the battery cycle and calendar lifetime with improved interfacial chemical passivation. This passivation is afforded by the strong surface dipoles imparted on the particles from Lewis acidic surface boron.

Electrodeposited Iron‐Incorporated Cobalt Phosphide for Improved Supercapacitor Applications

Advanced Energy and Sustainability Research, EarlyView.
The electrodeposition method has been used to synthesize Fe–CoP deposited on nickel foam, resulting in excellent cycling stability and capacitance retention compared to CoP and FeP. Furthermore, a detailed charge storage mechanism, emphasizing the enhanced electrochemical performance has been discussed. Supercapacitors have gained significant attention

Partially Oxidized Pd/PdO/CC Catalyst for Hydrogen Production at Anodic and Cathodic in a Formaldehyde & Water Coelectrolysis System

Advanced Energy and Sustainability Research, EarlyView.
This work presents a novel partially oxygen‐doped Pd/PdO/CC catalyst, enabling a dual‐hydrogen generation process at both the cathode and anode through formaldehyde–water coelectrolysis, significantly enhancing energy efficiency and sustainability. Partial oxidation is a strategic method to optimize catalytic materials, particularly for multifunctional

Bulk and Surface Reactivity of LiNi0.5Mn1.5O4 in Contact with (Acidic) Water

Advanced Energy and Sustainability Research, EarlyView.
The comprehensive investigation of the influence of (acidic) water on LiNi0.5Mn1.5O4 as cobalt‐free lithium‐ion battery cathode material reveals that such treatment particularly affects a very thin layer at the particle surface, while the bulk material remains unaffected.

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.
