Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

3D‐Printed Coil Immobilized Enzyme Reactors for Laccase Biocatalysis in Single‐ and Two‐Phase Flow
Development of 3D‐printed immobilized enzyme reactors functionalized with laccase for continuous‐flow biocatalysis. Surface coupling and reactor design enhanced stability and mass transfer, enabling efficient and reusable biocatalytic processes.

Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Normal forms for parabolic partial differential equations
Summary: The authors begin a study of normal form theorems for parabolic partial differential equations \[ \partial_ t v= \partial_ x^ 2 v+\mu v-v^ 3- \varepsilon R(v), \] where \(R\) is a polynomial whose terms are all of degree 4 or higher. They show that despite the presence of resonances one can construct a partial normal form for perturbations of ...

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...
