Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Toward Symbolic Integration of Elliptic Integrals

Journal of Symbolic Computation, 1999
Integrals are considered of the form \(\int_y^x\prod_{i=1}^h(a_i+b_it)^{-1/2} \prod_{j=1}^n(a_j+b_jt)^{m_j} dt\), where \(h=3\) or \(4\), \(n\geq h\), the \(m\)'s are integers, and ...

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Nonuniformly elliptic energy integrals with p,q-growth

Nonlinear Analysis, 2018
We study the local boundedness of minimizers of a nonuniformly energy integral of the form ∫ Ω f ( x , D v ) d x under p , q -growth conditions of the type λ ( x ) | ξ | p ≤ f ( x , ξ ) ≤ μ ( x ) 1 + | ξ | q for some exponents q ≥ p > 1 and with ...

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

Advanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.

Sharp bounds of the number of zeros of Abelian integrals with parameters

Electronic Journal of Differential Equations, 2014
In this article, we study four Abelian integrals over compact level curves of four sixth-degree hyper-elliptic Hamiltonians with parameters. We prove that the sharp bound of the number of zeros for each Abelian integral is 2. The proofs rely mainly

Amplitudes, supersymmetric black hole scattering at O G 5 $$ \mathcal{O}\left({G}^5\right) $$ , and loop integration

Journal of High Energy Physics
We compute the potential-graviton contribution to the scattering amplitude, the radial action, and the scattering angle of two extremal black holes in N $$ \mathcal{N} $$ = 8 supergravity at the fifth post-Minkowskian order and to next-to-leading order ...

MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

Advanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...
