Graphite crystallizer and its surface quality as a factor affecting the copper continuous casting process

open access: yesMetalurgija, 2022
Pure copper is one of the best conducting metals among known materials, making it the first choice for wires and microwires. However, before subjecting to metal working, the material is being manufactured in the continuous casting lines. The experimental

Beyond Conventional: A Review of Phytochemical‐Hydrogel Systems Enhanced by AI and 3D Printing for Chronic Wound Management

open access: yesAdvanced Science, EarlyView.
This review systematically bridges chronic wound pathology with natural phytochemical hydrogel therapeutics. A pathology‐to‐phytochemical mechanistic mapping framework is established, linking specific wound hallmarks to targeted phytochemical interventions.

Ferro-metals processing can be hazardous to your health [PDF]

open access: yes
Ferro-metals (or Ferro-alloys) are used in making steel, to add different characteristics to the steel. The ferro-metals are often in the form of rocks. The ferro-metals are produced by heating the ore of the needed additive with iron ore.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Mutual solubility of ammonium perrhenate in solutions containing ammonium salts

open access: yesScientific Reports
Mutual solubility measurements were carried out for three multi-component systems of ammonium perrhenate (NH4ReO4) and one of the ammonium salts (NH4NO3, NH4Cl or (NH4)2SO4) dissolved in water.

Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

open access: yesAdvanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

The In Situ Electrochemical−Chemical Cascade Strategy for Pyruvic Acid Synthesis

open access: yesAdvanced Science, EarlyView.
By employing an “unsaturation−oxygen coordination engineering” strategy, the local coordination environment is regulated to achieve efficient electrochemical synthesis of H2O2. Importantly, an electrochemical−chemical coupled cascade strategy is utilized for the efficient preparation of pyruvic acid via lactic acid oxidation. ABSTRACT Hydrogen peroxide

Janus Reactivity of a Mononuclear Non‐Heme Iron(III)‐Peroxo Complex Toward Indole Oxidation

open access: yesAngewandte Chemie, EarlyView.
The iron(III)‐peroxo complex [FeIII(O2)(12‐TMC)]+ exhibits bifurcating pathways in indole oxidation. N─H indoles undergo N─H H‐atom abstraction, supported by a KIE of 5.2 for N─H/N–D 2,3‐dimethylindoles, whereas N‐methylindoles react via electrophilic addition of the iron‐peroxo group to the C2–C3 double bond of the indole ring, forming iron ...
