Characterization of the orf31-petG gene cluster from the plastid genome of Populus deltoides

, 1997
The orf31-petG gene cluster is located approximately 1.2 kb away from the psbEFLJ operon in the chloroplast genome of Populus deltoides. The orf31 (ycf7 encodes an unidentified polypeptide while the petG gene encodes subunit V of an important component ...

Circularity in 3D Printing with Poly(Ethylene Terephthalate Glycol): Copolymer Composition Dependent Degradation During Recycling

Macromolecular Materials and Engineering
Reduced environmental impact is commonly cited as a driver for additive manufacturing, but non‐circular end‐of‐life disposition of the printed materials reduces these advantages.

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

Dental Arch Expansion With In‐House Clear Aligners: An Exploratory Prospective Clinical Study on Torque, Vertical Control and Attachment Configuration

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective To evaluate the short‐term efficacy of transverse dental arch expansion with in‐house aligners (IHA) by comparing planned and achieved buccolingual movements, and secondarily to explore torque expression, vertical control and the influence of attachment design/position using a contralateral within‐subject approach.

Tracing the Untraceable: A Review and Discussion on the Forensic Attribution of 3D‐Printed Firearms

WIREs Forensic Science, Volume 8, Issue 4, December 2026.
3D‐printed firearms are rapidly evolving and challenge traditional forensic identification. This review highlights emerging attribution methods, from deposition striae and base‐plate marks to polymer and GSR residual traces, firing marks, and quantitative imaging, identifying the research needed to support robust forensic attribution interpretation and
