Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

open access: yesAdvanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

The Practitioner\u27s Corner: An exploration of municipal active living charter development and advocacy [PDF]

open access: yes, 2013
Background: Numerous municipal active living-­‐related charters have been adopted to promote physical activity in Canada throughout the past decade. Despite this trend, there are few published critical examinations of the process through which charters ...

Three‐dimensional Antimony Sulfide Based Flat Optics

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Interpreting Monastic Cartularies in Northwest Europe, 900-1200: Thirty Years of Scholarship

open access: yesStudia Historica. Historia Medieval
Since the publication of Les cartulaires in 1993, the study of cartularies has evolved in two main directions: as part of a broader documentary culture and studying regional or textual patterns using digital tools and postmodern approaches.

The Social Context of the Charter: Times and Places of Documentation in Early Medieval Iberia (711-1031)

open access: yesStudia Historica. Historia Medieval, 2023
When and where was a charter written? Whether the scribe prepared it before, during, or after a transaction, on the spot or elsewhere, conditions its standing as historical evidence.

Traditional Public School and Charter School Funding in Arkansas (UPDATED) [PDF]

open access: yes, 2014
The existence and expansion of charter schools in Arkansas continue to be controversial. Proponents of charters argue that charter schools are unfairly burdened because they do not have access to local property tax revenue.

Biointerface Membranes Orchestrating Site‐Specific Osteoimmunomodulatory and Antibacterial Effects for Enhanced Osseous Regeneration in Periodontal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...

A tale of two charters [PDF]

open access: yes, 2005
Charters are official commitments to quality and reform. Belgium introduced its Charter of the User of Public Services in 1993. The federal administration’s Copernicus reform began in 1999 and had a strong external outlook. It therefore may be considered

Voltage‐Gated Dedoping of n‐Doped Poly(benzodifurandione) as an Interfacial Protective Mechanism in Electrochromic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electrochromic polymer stability under overpotential is improved by inserting an ultrathin, transparent n‐doped poly(benzodifurandione) interlayer between indium tin oxide and a poly(3,4‐propylenedioxythiophene)‐based electrochromic polymer. The interlayer supports rapid switching at operating bias, then becomes resistive near +0.8 V to suppress excess
