Electrophoretic Deposition of MnO2 using Folic Acid as Advanced Dispersing Agent

open access: yesJournal of Amasya University the Institute of Sciences and Technology, 2020
The deposition mechanism of MnO2 has been investigated by using electrophoretic deposition (EPD) method. Folic acid, a biocompatible dispersing agent, was analyzed for the dispersion of MnO2 and MWCNT and anodic deposition of MnO2 in ethanol.

Induction rites and wrongs: the educational vandalism of new teachers' professional development [PDF]

open access: yes, 2006
The central theme of this paper is that teachers’ professional development in England is not being taken as seriously as it needs to be. With reference to the induction of newly-qualified teachers and the early professional development pilot schemes, it ...

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres

open access: yesPolymer Composites, EarlyView.
Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...

Exceptional Points of Degeneracy Induced by Linear Time-Periodic Variation [PDF]

open access: yes, 2019
We present a general theory of exceptional points of degeneracy (EPD) in periodically time-variant systems. We show that even a single resonator with a time-periodic component is able to develop EPDs, contrary to parity-time- (PT) symmetric systems that ...

Sensing-Throughput Tradeoff for Interweave Cognitive Radio System: A Deployment-Centric Viewpoint [PDF]

open access: yes, 2015
Secondary access to the licensed spectrum is viable only if interference is avoided at the primary system. In this regard, different paradigms have been conceptualized in the existing literature.

Life Cycle Assessment of Closed‐Loop Opaque Recycled Polyethylene Terephthalate (rPET) Bottles for UHT Milk

open access: yesPackaging Technology and Science, EarlyView.
The study quantifies environmental impacts of 1 L of ultra‐high‐temperature milk bottles, comparing a 50% recycled opaque PET (rPET) bottle with 100% virgin PET bottles under closed‐loop and non‐closed‐loop recycling scenarios. Results show that 50% opaque rPET bottles outperform 100% virgin PET bottles across all impact categories, enabled by an ...

Profitable Scheduling on Multiple Speed-Scalable Processors [PDF]

open access: yes, 2012
We present a new online algorithm for profit-oriented scheduling on multiple speed-scalable processors. Moreover, we provide a tight analysis of the algorithm's competitiveness.

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

open access: yesPackaging 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 ...

Lossy Compression with Privacy Constraints: Optimality of Polar Codes

open access: yes, 2015
A lossy source coding problem with privacy constraint is studied in which two correlated discrete sources $X$ and $Y$ are compressed into a reconstruction $\hat{X}$ with some prescribed distortion $D$.

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...
