This white paper presents the MF Biocompatible VPP Framework, positioning monomer-free formulation as an engineering strategy for reducing regulatory, toxicological and extractables-related risk in professional manufacturing workflows. Biocompatibility is not only a material label. It depends on formulation architectu…
This white paper covers 3Dresyn PEEK-like, a high-performance VPP photopolymer designed to approximate a PEEK-like engineering positioning with ultra-high flexural strength in the 120–140 MPa range. The material is positioned for applications requiring high stiffness, high flexural performance and engineering durabili…
This white paper maps the engineering and functional VPP resin portfolio for SLA, DLP and LCD platforms, from rigid and tough grades to elastic, high-temperature, optical, conductive and application-specific material systems. The portfolio is organised by real structural and functional behaviour rather than generic re…
Problem. Additive manufacturing of electrically functional parts has progressed from filament-based conductive thermoplastics into vat photopolymerisation (VPP) systems capable of micron-scale resolution, enabling printed electronics, electrostatic-control fixtures, bioelectronics, embedded sensors, sacrificial conduc…
This white paper covers the 3Dresyns Cold Fusion SLS powder-binder family for CMF, CCF, CPF and CEPF routes: a binder-assisted, mould-free indirect sintering route on standard SLS hardware, where the laser fuses a co-binder — or, with the self-sufficient CF3, the binder itself — to form the green part, and final densi…
Nanomagnetic devices are of great interest in digital hardware because of their non-volatility and dynamic ability to change magnetization but suffer from high switching error rates and temperature sensitivity. Magnetostrictive nanomagnets that utilize strain to switch between stable magnetization states encoding bit…
We present the optical design of VIPER: a high-resolution, multimode fiber-fed, narrowband, cross-dispersed, seeing-limited spectrograph based on a Virtually Imaged Phased Array (VIPA), a spectral disperser that provides higher dispersion and a more compact form factor than conventional diffraction gratings. VIPER is…
HARMONI is the first light, adaptive optics assisted, near-IR integral field spectrograph for the ELT. It covers a spectral range from 800 nm to 2450 nm with resolving powers from 3000 to 7000 and spatial sampling of 25 mas and 6 mas. It can operate in two adaptive optics modes - SCAO (including a high contrast capabi…
Electrochemical sensors based on PET track-etched membranes grafted with poly(N-vinylformamide-co-methacrylic acid) [PET TeMs-g-p(NVFA-MAA)] were developed. The modification, structure, and physicochemical properties of the grafted PET membranes were characterized by SEM, AFM, EDX, FTIR spectroscopy and contact-angle…
The ability to precisely control the interaction between functional inks and substrates is essential for achieving reliable performance in printed materials and devices. These interactions influence ink spreading, deposition behavior, pattern formation, and ultimately the functionality of the printed structures. This…
Abstract The essential physical processes underlying the phenomenon of high-Tc superconductivity in cuprates occur in the $$CuO_2$$ planes, found in these materials. The dynamics of the active electrons belonging to such planes is well described by the Three Bands Hubbard Model (3BHM). The complexity of such model, ho…
One of the key challenges in fuel cell systems control is avoiding local oxygen starvation, which can lead to the degradation of the catalyst layer. Reduced-order model-based control strategies can help to detect this situation and apply corrective measures in terms of working pressure or stoichiometry in the cathode…
Negative ion based neutral beam injection (NBI) systems will be used for heating and current drive at the ITER tokamak and require stringent beam quality. Including a beamlet core divergence of less than 7 mrad and high uniformity across individual beamlets (better than 90%), at extracted current densities of 329 A/m2…
Abstract While spin-adapted time-dependent density functional theory (TDDFT) approaches significantly improve the excitation energies and gradients of open-shell molecules, the effect of spin-adaptation on nonadiabatic coupling matrix elements (NACMEs) remains unknown for spin-conserving excitations. In this article,…
The increasing global demand for sustainable, high-energy-density energy storage systems has stimulated extensive research into alternatives to conventional lithium-ion batteries. Among the most promising candidates, lithium-sulfur batteries (LSBs) have attracted considerable attention because of their high theoretica…
Electrochemical conversion of CO2 into industrially valuable chemicals such as ethylene and ethanol represent a critical strategy for reducing atmospheric CO2 levels, storing renewable electricity in chemical form, and minimizing reliance on virgin fossil resources for chemical production. However, achieving high prod…
Additive manufacturing (AM) enables the fabrication of complex metallic components through layer-by-layer processing directly from digital models. Among AM techniques, material extrusion–based processes such as fused filament fabrication (FFF) provide an accessible method for producing metal parts using filament feeds…
Molecular hydrogen production (H2) via electrocatalytic water splitting presents a unique opportunity to significantly decrease global dependence on fossil fuels. Since water splitting is a nonspontaneous reaction, careful consideration of the materials used for application to the hydrogen evolution reaction (HER). To…
Abstract A persistent challenge in plasmonic upconversion is decoupling pump-field enhancement from emission-side local-density-of-optical-states (LDOS) engineering to achieve selective band manipulation. Here, we show that a corrugated SU-8/Au/Al2O3 grating coated with a NaYF4:Yb/Er upconversion nanoparticle (UCNP) m…
The Adhesion–Triboelectric–Corona–Maillard (ATCM) Model presents the first fully naturalistic, unified framework linking forensic pathopathology, bio‑rheology, triboelectric physics, plasma chemistry, and low‑temperature organic reactions to explain the image on the Shroud of Turin. The mechanism demonstrates that tim…
