Hawking radiation in dispersive media

open access: yes, 2011
Hawking radiation, despite its presence in theoretical physics for over thirty years, remains elusive and undetected. It also suffers, in its original context of gravitational black holes, from conceptual difficulties.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Multimodal Perception and Machine Learning‐Empowered Human Machine Interfaces With Double‐Network Hydrogel Fibers

open access: yesAdvanced Functional Materials, EarlyView.
This work develops polyacrylamide‐alginate (PAM‐Alg) double‐network hydrogel fibers for multimodal perception and intelligent human‐machine interfaces. The covalent‐ionic network provides high strength, toughness, and stable conductivity. Easily woven into wearables and integrated with soft robots, the fibers enable object and temperature recognitions ...

Simultaneous Raman and FTIR‐ATR Spectroscopy Techniques Combined With Chemometrics: Characterization and Comparison of Donkey Milk Adulteration

open access: yes
Due to its nutritional qualities, donkey milk is a newly popular food. Because it has a high added value, it may be adulterated with using cheaper milks, like cow milk. This study has investigated a rapid method for the authentication of pure donkey milk

Dynamic Interfacial Chemistry of Choline Chloride as Electrolyte Additive for Stable Zn‐Iodine Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Choline chloride (ChCl) additive enables dynamic interface engineering in Zn‐I2 batteries by forming hydrophobic polyiodide complexes and a Zn‐stabilizing Ch+‐rich layer under electric field modulation. This dual‐function strategy suppresses iodine hydrolysis and dendrite formation, while optimizing Zn2+ solvation and transport for high‐efficiency ...

Stand-off Spatially Offset Raman spectroscopy

open access: yes, 2014
Stand-off Raman spectroscopy is a versatile tool in a range of analytical applications, such as safety (detection of explosives at safe distances) or geosciences (planetary exploration).

The Raman spectrum of rock-salt

open access: yes, 1946
Using a non-luminescent crystal of rock-salt, a quartz spectrograph with a fine slit, and the 2536.5 A resonance radiations of mercury arc as exciter, the Raman effect in rock-salt has been studied.

Blood Biomarkers and Surface‐Enhanced Raman Spectroscopy for Gout: A Comprehensive Review

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustrating gout disease progression from asymptomatic hyperuricemia to chronic tophaceous disease, highlighting the limitations of conventional imaging and biochemical diagnostics and the potential of engineered SERS platforms for ultrasensitive blood‐based detection of urate‐related biomarkers across disease stages, with the color gradient

Raman spectrum of ammonia IV

open access: yes, 2006
We present an extensive analysis of the Raman spectrum of ammonia IV, for both NH3 and ND3, between 6 and 11 GPa. Polarized Raman scattering experiments were performed at low temperature (20–80 K) on single-crystalline samples grown in a diamond anvil ...
