EMT,Pseudo-EMT and all that Improvement and Superpotentials

open access: yes
Within Einstein-Hilbert gravity, higher derivatives and a scalar field as representative of matter different versions of tensorlike quantities are discussed.The concepts of improvement and superpotential help to understand the details of their construction and meaning.

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

open access: yesAdvanced Functional Materials, EarlyView.
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.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Space-time couplings in ultrashort lasers with arbitrary nonparaxial focusing

open access: yesNanophotonics
Space-time separability is commonly assumed in the theoretical description of laser beams. However, recent progresses have demonstrated that this assumption often breaks down for ultrashort realistic pulses, giving rise to spatio-temporal effects that ...

3D Bioprinted Head and Neck Squamous Cell Carcinoma (HNSCC) Model Using Tunicate Derived Nanocellulose (NC) Bioink

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
A 3D bioprinted HNSCC model for use in anti‐cancer drug testing is established in proof‐of‐concept. The innovative tunicate‐derived nanocellulose hydrogel proved to be a viable alternative to gelatin‐based hydrogel, offering improved bioprintability for HNSCC model establishment.
