Cipher-image compression by using compressive sensing and interweaving permutation

open access: yesJournal of King Saud University: Computer and Information Sciences
Recently, compressing cipher images by using compressive sensing (CS) has attracted a lot of attention. However, the previous CS-based works cannot provide satisfactory compression performance.

Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

A New Methodology for Assessing Macromolecular Click Reactions and Its Application to Amine--Tertiary Isocyanate Coupling for Polymer Ligation. [PDF]

open access: yes, 2016
Click reactions have provided access to an array of remarkably complex polymer architectures. However, the term "click" is often applied inaccurately to polymer ligation reactions that fail to respect the criteria that typify a true "click" reaction ...

4D‐Printable Poly(Thio)urethane Photoresins With Reactive Oxygen Species Responsiveness and Anti‐Inflammatory Functionality

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces UV‐curable poly(thio)urethane (PSU) thermosets as 4D printable scaffolds responsive to oxidative stress. PSU networks with 100 wt.% polypropylene glycol (PPG) effectively suppress inflammatory markers in microglial cells to basal values.

Mixed connective tissue disease — enigma variations? [PDF]

open access: yes, 2017
In 1972, Sharp and colleagues described a new autoimmune rheumatic disease which they called mixed connective tissue disease (MCTD), characterized by overlapping features of systemic sclerosis (SSc), systemic lupus erythematosus (SLE), polymyositis ...

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

open access: yesAdvanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Glycine-assisted hydrothermal synthesis of NiCo2S4 as an active electrode material for supercapacitors

open access: yesJournal of Science: Advanced Materials and Devices, 2019
Nickel cobalt sulfide (NCS) was synthesized from nickel and cobalt nitrate (NCS-1) by a hydrothermal method. In another method, nickel cobalt sulfide (NCS-2) was also synthesized from hydrothermally synthesized nickel cobalt oxide (NCO). The syntheses of

Evidence for suppressed metallicity on the surface of La2-xSrxCuO4 and Nd2-xCexCuO4 [PDF]

open access: yes, 2005
Hard X-ray Photoemission spectroscopy (PES) of copper core electronic states, with a probing depth of $\sim$60 \AA, is used to show that the Zhang-Rice singlet feature is present in La$_2$CuO$_4$ but is absent in Nd$_2$CuO$_4$.

Magnetic Textiles: A Review of Materials, Fabrication, Properties, and Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Magnetic textiles (M‐textiles) are emerging as a programmable materials platform that merges magnetic matter with hierarchical textile structures. This article consolidates magnetic material classes, textile architectures, and fabrication and magnetization strategies, revealing structure–property–function relationships that govern magneto‐mechanical ...
