ABSTRACT Crosslinked polyethylene (XLPE) is the benchmark insulation for high‐voltage direct‐current (HVDC) cables, yet its amorphous phase remains the Achilles' heel—vulnerable to space charge accumulation, oxygen permeation, and thermo‐oxidative degradation that synergistically trigger premature failure. Here, we re…
THE ALCHEMY OF STONE The Definitive Molecular Science of Marble Pigmentation and Engineered Composites
Globally, diabetes affects approximately 589 million people and represents a major public health challenge, is a severe health epidemic, especially in low- and middle-income regions where its incidence continues to rising. The main challenge is the increase in diabetic complications and antibiotic resistance linked to…
Three layered rare-earth hydrogenselenite–selenite hydrates, Ln(HSeO3)(SeO3)∙2H2O (Ln = Yb, Dy, Eu), were synthesized under hydrothermal conditions and systematically characterized. Single-crystal and powder X-ray diffraction show that the compounds are isostructural and crystallize in the non-centrosymmetric orthorho…
ABSTRACT Pancharatnam‐Berry (PB) phase metasurfaces capable of continuous broadband phase modulation solely through rotation control of meta‐atoms have emerged as a pivotal branch in metasurface research. To achieve spin‐decoupled wavefront control in PB metasurfaces, current approaches introduce additional resonant p…
This paper introduces the concept of Molecular Phase Space Reconstruction (MPSR), a novel approach to understanding chemical systems that addresses the limitations of traditional methods. The core idea centers on moving beyond representing molecules as static structures and instead conceptualizing them as trajectories…
This paper introduces the theory of Chemical Phase Transition of Reactivity (CPTR), proposing that reactivity itself can undergo sudden phase transitions, analogous to phase transitions observed in magnetism. The core concept revolves around the continuous variation of reactivity, suggesting that reactivity can transi…
This paper introduces the Molecular Approximation Hierarchy (MAH), a rigorous hierarchical approach to chemical approximations. The MAH establishes a systematic progression of approximations, denoted as [L₀ → L₁ → L₂ → ...], where each level represents an increased level of information and a corresponding reduction in…
ABSTRACT Catheter‐related bloodstream infection (CRBSI) is an important clinical problem that causes significant mortality and excess economic cost. Recent epidemiological trends indicate a shift in CRBSI pathogens from Gram‐positive to Gram‐negative bacilli, among which Pseudomonas aeruginosa , Klebsiella pneumoniae…
This paper introduces the Reaction Information Bottleneck Theory (RIBT), a novel framework for understanding and modeling complex chemical reactions. Traditional approaches to reaction dynamics often rely on energy minimization, which struggles to accurately capture the intricate details of reaction pathways, particul…
0pat (pure mathlib) formalization of the Riemann direction unified observation (Exercise XXXVII). Four tasks, all machine-verified in Lean 4 with zero axioms beyond mathlib: (1) zero-order flip direction — reflection symmetry sigma(t)=2t0-t (involution) plus multiplicative phase cancellation u(sigma(t))/u(t) -> (-1)^m…
FePt-X nanocomposite thin film (X is a non-magnetic segregant) is a critical enabling material for ultrahigh-capacity magnetic recording, but a time- and cost-efficient strategy to identify process parameters that yield desirable microstructure features has remained scarce. Here, we present a computational framework,…
Abstract Although tremendous progress has been made in recent years in the field of polyhydride superconductors, the realization of high critical temperature (Tc) superconductivity still relies on formidable high pressures. Searching for superconducting hydrides at lower pressures is of particular importance. Here we…
The Perfect Cast white paper presents the 3Dresyns castable VPP portfolio as a workflow-based system organised around three pattern-removal mechanisms: thermal burnout, heat melt-and-flow and water dissolution. Grade selection is additionally matched to printer-power compatibility within the burnout family. Pattern-re…
This white paper covers reactive reinforced composites, focusing on filler-matrix interface engineering, reinforcement strategy and controlled composite behaviour in VPP materials. Composite performance depends not only on filler loading but also on dispersion, interface chemistry, cure compatibility, viscosity, sedim…
국문 초록 주사전자현미경(SEM)의 표준 구성은 시료를 진공에 두는 것을 전제하며, 이 전제는 60년간 자명한 배경으로 취급되어 왔다. 그러나 관찰 수요가 첨단 패키징의 대형·이종 시료와 함습 유기물·액상·부도체로 확장되면서, '측정 불가' 판정의 상당수가 시료의 물리 한계가 아니라 환경 전제의 산물임이 드러나고 있다. 본 논문은 이 문제를 정식화한다. (1) 진공 전제가 시료를 배제하는 기제를 네 유형 — E1 기하 배제(챔버·스테이지 적재 한계), E2 표면 배제(부도체 대전과 코팅 강제), E3 상태 배제(아웃개싱·수분 이탈·변형 등 진공 유발 변질), E4…

Education and research users require materials that combine straightforward handling, broad experimentation, clear…
This white paper covers radiopaque and radio-transparent VPP photopolymers for diagnostic, imaging, shielding and device-development workflows where interaction with X-rays or other radiation-relevant modalities is part of the material function. Radiopacity and radio-transparency are functional properties that must be…
This white paper covers the Bio-Scaffolds portfolio for tissue-engineering and research workflows using SLA, DLP and LCD photopolymerisation.
