Alfvén Waves in the Lower Solar Atmosphere [PDF]

open access: yesScience, 2009
The flow of energy through the solar atmosphere and the heating of the Sun's outer regions are still not understood. Here, we report the detection of oscillatory phenomena associated with a large bright-point group that is 430,000 square kilometers in area and located near the solar disk center.

High‐Performance, Air‐Stable and Eco‐Friendly Terpene‐Processed Organic Solar Cells via Solvent‐Composition‐Controlled Film Formation Kinetics

open access: yesAdvanced Functional Materials, EarlyView.
Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.

Radiation hydrodynamics in simulations of the solar atmosphere

open access: yes, 2020
Nearly all energy generated by fusion in the solar core is ultimately radiated away into space in the solar atmosphere, while the remaining energy is carried away in the form of neutrinos.

Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Modelling 3D magnetic networks in a realistic solar atmosphere [PDF]

open access: yes, 2019
The magnetic network extending from the photosphere (solar radius \simeq R_\odot) to lower corona (R_\odot + 10 Mm) plays an important role in the heating mechanisms of the solar atmosphere. Here we further develop the models with realistic open magnetic

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities

open access: yesAdvanced Functional Materials, EarlyView.
We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Self‐Powered, Ultra‐Sensitive InGaAs/ITO Nanowire Radial Junction Infrared Photodiode for Low Flux Imaging at Room Temperature

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a self‐powered InGaAs nanowire photodetector achieving single‐photon‐level sensitivity in the shortwave infrared at non‐cryogenic temperatures. The device demonstrates high‐speed imaging capabilities even under extremely low‐flux conditions.

Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...
