Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

open access: yesAdvanced Functional Materials, Volume 35, Issue 27, July 3, 2025.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

open access: yesAdvanced Science, Volume 12, Issue 25, July 3, 2025.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

Microfluidic Systems in Cancer Diagnosis: Advancing Exosome and CTC Detection From Laboratory Research to Clinical Application

open access: yesNano Select, Volume 6, Issue 7, July 2025.
Detection of cancer through the identification of EV markers and CTCs using microfluidic systems is rapidly advancing. These markers are typically identified from liquid biopsy samples, which offer a highly favorable alternative to traditional biopsy methods due to their non‐invasive nature.

Three-dimensional direct lithography of stable quantum dots in hybrid glass

open access: yesInternational Journal of Extreme Manufacturing
Semiconductor quantum dots (QDs), as high-performance materials, play an essential role in contemporary industry, mainly due to their high photoluminescent quantum yield, wide absorption characteristics, and size-dependent light emission. It is essential

Surface rippling induced by periodic instabilities on a polymer surface

open access: yesNew Journal of Physics, 2015
When the shear stress on a compliant surface exceeds the yield strength of the material, a periodic wrinkle pattern is often observed. This phenomenon has been also recognized at the nanometer scale on polymers, metals, ionic crystals and semiconductors.

Subwavelength Nanostructuring of Gold Films by Apertureless Scanning Probe Lithography Assisted by a Femtosecond Fiber Laser Oscillator

open access: yesNanomaterials, 2018
Optical methods in nanolithography have been traditionally limited by Abbe’s diffraction limit. One method able to overcome this barrier is apertureless scanning probe lithography assisted by laser.
