Technology and the Machine for Rasterized Facsimile Engaving of Art Images on Minerals [PDF]

open access: yesActa Montanistica Slovaca, 2005
Facsimile copying of images on polished mineral surfaces can be performed by rastration (dithering). when the original halftone image is replaced by the microstroke image.

Incorporation of Natural Antimicrobial Agents Into Thermoplastic Polymers for Food Applications: Strategies, Efficacy, Challenges and Future Directions

open access: yesPackaging Technology and Science, EarlyView.
This graphical abstract summarizes the main strategies for incorporating natural antimicrobial agents into thermoplastic food packaging polymers, including melt processing, surface deposition, controlled release and chemical immobilization. It highlights the major classes of natural antimicrobials, key advantages such as microbial growth reduction and ...

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Smuggling Sovereignty: Trade, Transgression, and State Authority

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT Global supply chains are saturated with transgressions—corruption, smuggling, document forgery, and other practices that blur the line between legality and illegality. States do not merely endure these practices; they actively shape the conditions for them, producing the very illegal systems they then claim to police.

Laser‐Assisted In Situ Fabrication of rGO/Bi2O3 Nanocomposites for Heavy Metal Sensing

open access: yesSmall, EarlyView.
Rapid CO2 laser irradiation drives the in situ formation of Bi2O3 nanoplatelets within reduced graphene oxide, yielding flexible, reproducible electrodes with excellent stripping voltammetric performance toward trace heavy metals. ABSTRACT In this work, we introduce a laser‐assisted approach to synthesize reduced graphene oxide/bismuth oxide (III) (rGO/

Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting

open access: yesSmall, EarlyView.
Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

open access: yesThe Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

The Kieperts’ Asia Minor Ancient and Ottoman: Capstones of Route-Based Cartography

open access: yesHistory of Classical Scholarship
Two ambitious Asia Minor map series by the Kieperts — Heinrich’s lithographed Specialkarte and Richard’s engraved Karte von Kleinasien — are probed here for the first time. What can be recovered about their planning, production, revision and impact from

Interdisciplinary learning combining engravings and poems by teachers in initial training

open access: yesFrontiers in Education
Interdisciplinary is proposed to address a technologic knowledge-based society. This research employs quantitative methodology to analyze the perception of an integrated interdisciplinary practice involving engraving and poetry among 63 teachers in ...

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

open access: yesWildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.
