Sn-3Ag-0.5Cu-xBi alloys (SAC305-xBi) represent promising lead-free alternatives for low-temperature soldering. Low Bi concentrations can strengthen SAC-based solders through solid-solution strengthening, refining β–Sn grains and transforming needle-like Ag3Sn phases into equiaxed morphologies. Howe…
The concept of electronic orbital topology (EOT) has traditionally been treated as a static property of a material, determined by its crystal symmetry and electronic band structure. In this paper we introduce the notion of Electron Orbital Topology Migration (EOTM), a dynamic process in which the o…
A gym bag under the desk revealed more than camping gear—it held the working woodworker's essential toolkit. David Ohnstad unpacks the hand planes, Japanese saws, chisels, and leather rolls that serious makers actually carry to every project. Full article: https://david-ohnstad.com/essential-hand-t…
Sustainable machining of composite materials requires optimizing conflicting responses influenced by limited experimental datasets, trade-offs, nonlinear process variables, and response variability. This study proposes a hybrid framework (Gaussian Process Regression—Method based on the Removal Effe…
Biodiversity monitoring is expanding beyond species counts toward integrated assessment of biological, chemical, physical, and geographic conditions. Microplastics and nanoplastics (MPs/NPs) are now documented across freshwater, marine, terrestrial, sedimentary, and biological systems, yet measurem…
Lattice structures, also known as porous or cellular structures, are lightweight architectures composed of periodically repeated geometric patterns with favorable mechanical performance, stiffness, and energy absorption capabilities. This study investigates the deformation behavior and compressive…
The coexistence of superconductivity and nontrivial band topology has opened a new frontier for designing robust quantum devices. In this work, we introduce the concept of a Superconducting Topological Memory State (STMS), a class of quantum states in which a superconductor preserves a record of it…
The woodworking internet preaches that bombproof joinery like mortise-and-tenon and through-dovetails are always superior. But this hierarchy ignores a crucial truth: the right joint depends on your application, not just raw strength. Full article: https://david-ohnstad.com/woodworking-joints-stren…
The electronic properties of crystalline solids have traditionally been described by the occupancy of atomic orbitals and the resulting band structure derived from Bloch wave functions. Recent advances in low‑dimensional systems and strong correlation physics suggest that electrons may form collect…
A new class of quantum memory is proposed, termed the Superconducting Topological Memory State (STMS). In this framework the macroscopic phase of a superconducting condensate is not only determined by the instantaneous Hamiltonian but also encodes a history of the system's topological configuration…
CFD is examined in this chapter to analyze the safety, risk mitigation, and performance of hydrogen storage systems. The mechanisms of mass and heat transfer governing hydrogen in high-pressure, material-based, and cryogenic storage systems are initially covered, with a focus on diffusion resistanc…
Abstract To address the challenge of mixed plastic waste management, we present a one-pot hydrodeoxygenation (HDO) process that selectively converts mixed oxygenated aromatic plastics including polyethylene terephthalate (PET), polycarbonate (PC), polyphenyl ether (PPO), and bisphenol-A-based epoxy…
The concept of entanglement in many‑body physics has traditionally focused on spin or particle‑number degrees of freedom. Here we introduce a novel class of fermionic quantum phases in which orbital degrees of freedom of identical particles become entangled across spatially distinct sites. We const…
Constructing artificial assemblies that combine proteins and synthetic ligands has been hampered by the lack of protein-ligand interfaces that are sufficiently large and organized to enable precise structural control. Here ribosome display selection is used to identify a protein that binds a helica…
FINDING: FMO complex exciton coupling ratio J/λ ≈ 2.86 correlates with optimal energy transfer efficiency in quantum networks. | MATH: J/λ ≈ 2.86; J = electronic coupling between chromophores, λ = reorganization energy. Optimal efficiency occurs when J/λ is tuned to this specific value, balancing c…
Abstract Pancreatic ductal adenocarcinoma (PDAC) remains difficult to treat because of inefficient intracellular drug delivery and robust redox defense. Here, we developed a glutathione (GSH)-responsive biomimetic nanoplatform, termed CMnMG, for magnetic resonance (MR) imaging and gemcitabine (GEM)…
ABSTRACT Circularly polarized electrochemiluminescence (CP‐ECL) provides an emerging route to encode chiral information into electrochemically generated light, but current strategies largely rely on intrinsically chiral luminophores, limiting molecular diversity, device integration, and dissymmetry…
This thesis reports the development of functional chitosan-based biomaterials through microextrusion of viscous collodions and (bio)inks. Anisotropic fiber and hydrogel hybrid materials of enhanced mechanical performance and good biological properties were produced by respectively using gel spinnin…
Abstract Accurate detection of both subtle and large deformations remains a major challenge for hydrogel-based wearable strain sensors. Here, we report a multifunctional phase-separated hydrogel composed of polyacrylamide (PAM), sodium alginate (SA), polyurethane (PU), and MXene nanosheets. The pha…
The static and dynamic magnetic responses of symmetric Fe/Al/Fe trilayers were investigated as a function of the thickness of the nonmagnetic spacer layer thickness, with tAl ranging from 0 to 2 nm. Samples showed ferromagnetic coupling between Fe layers for all values of tAl, despite presenting ch…
