Poly(ethylene terephthalate) (PET) is one of the most widely produced plastics, and enzymatic depolymerization offers a promising route to closed-loop recycling under mild conditions. However, most known bacterial PET hydrolases belong to a conserved canonical-fold cutinase family, leaving much of alpha/beta-hydrolase…
Nanopores in ultrathin membranes are central to single-molecule sensing, filtration, and energy conversion applications, yet fabrication of solid-state nanopores remains limited by fundamental trade-off between resolution, throughput, and tool complexity. Here, we report a scalable nanopore fabrication process that ex…
This paper proposes a unifying framework for understanding all chemical reactions based on the concept of Universal Chemical Symmetry Breaking (UCSB). It posits that every chemical transformation, regardless of its specific manifestation – be it oxidation-reduction, acid-base reactions, radical reactions, or rearrange…
This archive preserves the current research state of the HLV Layer-Origin programme and provides a reproducible pause/handoff package for subsequent work. The programme investigates whether a single six-dimensional cut-and-project parent structure can generate a finite three-dimensional carrier together with intrinsic…
Camphor, a naturally occurring bicyclic monoterpenoid, has attracted increasing interest as a structural scaffold for the construction of fluorescent probes owing to its rigid framework, facile functionalization, and favorable biocompatibility. In recent years, a variety of camphor-derived fluorescent probes have been…
The recently discovered heavy-fermion spin-triplet superconductor candidate UTe2 provides a rich platform for unconventional pairing and topological phenomena. However, limited has been known about its superconducting order parameters and their evolution with control parameters, largely due to the lack of appropriate…
Using a 1.2 mm diameter TC4 titanium alloy welding wire and an arc-based additive manufacturing system, thick-walled TC4 titanium alloy components were fabricated on forged TC4 titanium alloy base plates via a reciprocating scanning method. These components were subsequently annealed. The effects of annealing temperat…
This Technical Communication analyzes and evaluates the results and major conclusion drawn by the IJMC paper titled ‘Influence of Mn and S on the Properties of Cast Iron Part III—Testing and Analysis’ 1 and authored by Gundlach, R. Meyer, M. and Winardi, L. That paper concluded that the mathematical product of the man…
Abstract Most terpene-derived polymers reported to date are amorphous resins, elastomers, or cross-linked networks. Here we report a crystalline isotactic polyterpenoid, poly(4,8-dimethyl-1,7-nonadiene) (PDMND), synthesized from naturally abundant citronellal using a pyridylamido hafnium catalyst. Temperature-dependen…
Abstract Chirality-induced spin selectivity (CISS) enables chiral materials to generate spin-polarized currents, yet the structural origin of spin selectivity in intrinsically chiral inorganic nanostructures remains unclear. A central mechanistic challenge is to determine how the molecular chirality of surface ligands…
The performance and reliability of n-type organic field-effect transistors (OFETs) are strongly influenced by the interplay between semiconductor crystallinity and the metal/semiconductor interface. Here, we systematically investigate a series of diketopyrrolopyrrole (DPP)-based n-type polymers with identical backbone…
Abstract Enzymes that catalyze non-natural C–C bond-forming reactions are powerful tools in asymmetric synthesis, yet reprogramming their active sites to invert stereochemical outcome remains challenging. Building on our recently engineered S N Arase, S N Ar1.3, which performs enantioselective nucleophilic aromatic su…
Metal–organic frameworks (MOFs) are crystalline, highly porous hybrid materials constructed from metal ions or metal-oxo clusters coordinated to organic linkers. Their exceptionally high surface area, tunable pore chemistry, and structural programmability have driven rapid growth in pharmaceutical research on MOFs ove…
A one-dimensional Thue–Morse graphene photonic crystal (1D TMGPC) composed of alternating identical dielectric layers and graphene sheets is proposed, in which two distinct graphene chemical potentials are arranged according to a Thue–Morse quasi-periodic sequence. Using the transfer matrix method, we demonstrate that…
ABSTRACT Operating flexible sensors in diverse environments, especially underwater with limited power and communication, remains a significant challenge. Herein, we present a photopatterned tribo‐mechanoluminescent (TML) hydrogel that integrates stress‐induced luminescence and triboelectricity into a single, multifunc…
Waterjet propulsion systems manufactured by Additive Manufacturing (AM) offer potential advantages for lightweight marine applications, but experimental data on the static thrust performance of polymer-based waterjet thrusters remain limited. This study presents an experimental investigation of the static thrust perfo…
A falsifiable experimental protocol for testing the long-term survivability of cyclic thermal-storage systems. It separates thermal-state stability, regeneration completeness, intrinsic capacity retention, and cycle endurance, providing a controlled method to distinguish ordinary incomplete regeneration from genuine c…
Abstract Chitosan-based hydrogels have various applications in atmospheric water harvesting (AWH). These hydrogels exhibit good water absorption, compatibility with living systems, a 3D porous structure, and high water uptake and release capacity. The effectiveness of hydrogels depends primarily on cross-linking agent…
The development of thermally stable and application specific composites from local raw materials is important for refractory, insulating, filtration, and structural ceramic industries. This study investigates the thermal stability and decomposition behavior of bentonite clay (C), zirconium silicate (Z), and cow dung (…
Milk-derived extracellular-vesicles (mEVs) have emerged as a promising natural nanocarriers for nutraceutical and therapeutic applications, owing to their rich cargo of bioactive proteins, lipids, microRNAs, and metabolites, coupled with their inherent biocompatibility and stability. Their unique ability to withstand…
