4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

Advanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.

Boundary terms in string field theory

Journal of High Energy Physics
We supplement the string field theory action with boundary terms to make its variational principle well-posed. Central to our considerations is the violation of the stress-energy tensor conservation in non-compact CFTs due to the boundary terms.

Genus-one string amplitudes from conformal field theory

Journal of High Energy Physics, 2019
We explore and exploit the relation between non-planar correlators in N $$ \mathcal{N} $$ = 4 super-Yang-Mills, and higher-genus closed string amplitudes in type IIB string theory.

Cubic Twistorial String Field Theory

, 2004
Witten has recently proposed a string theory in twistor space whose D-instanton contributions are conjectured to compute N=4 super-Yang-Mills scattering amplitudes.

Closed Strings Tachyons and Non-Commutative Instabilities [PDF]

, 2003
We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type IIB string theory on C^3/Z_N orbifold singularities and the non ...

Intrinsically Soft Printed Electronics for Digitally Augmented Human Sensing and Vision

Advanced Functional Materials, EarlyView.
This work introduces a class of highly functional, multilayer flexible and stretchable circuits capable of digitally augmenting human sensing and vision. Studies in multi‐material soft composite inks yielded a formulation that enables overpass printing, self‐healing, and high‐resolution functionality.

A matrix model from string field theory

Frontiers in Physics, 2016
We demonstrate that a Hermitian matrix model can be derived from level truncated open string field theory with Chan-Paton factors. The Hermitian matrix is coupled with a scalar and U(N) vectors which are responsible for the D-brane at the tachyon vacuum.

Perturbative string theory from Newtonian limit of string geometry theory

European Physical Journal C: Particles and Fields, 2020
String geometry theory is one of the candidates of the non-perturbative formulation of string theory. In Sato (Int J Mod Phys A 34(23):1950126, 2019), the perturbative string theory is reproduced from a string geometry model coupled with a u(1) gauge ...

Normalization of D-instanton amplitudes

Journal of High Energy Physics, 2021
D-instanton amplitudes suffer from various infrared divergences associated with tachyonic or massless open string modes, leading to ambiguous contribution to string amplitudes.

On String Field Theory and Effective Actions

, 1992
A truncation of string field theory is compared with the duality invariant effective action of $D=4, N=4$ heterotic strings to cubic order. The three string vertex must satisfy a set of compatibility conditions.
