Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

open access: yesAdvanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

Senior moments.

open access: yesGenome biology, 2006
The problem with reaching 'senior faculty' status is the feeling that you have nothing much to contribute except experience, but the recently announced Neanderthal Genome Project might put things into perspective.

Improvement of Heat Stability of Paper Made From Sulfite and Kraft Pulps [PDF]

open access: yes, 1966
Paper made from bleached sulphite and sulphate pulps and then treated with sodium alginate and antimony resin solutions show far less physical and chemical degradation with heat than these same papers when not treated with these solutions.

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Online purchasing and the elderly [PDF]

open access: yesAnali Ekonomskog fakulteta u Subotici, 2015
Elderly consumers have become a more significant market segment in developed welfare countries, due to their increased numbers and income growth. While their importance in marketing terms is generally recognised in the West, their online presence is not.

Non-HDL cholesterol level and depression among Canadian elderly—a cross-sectional analysis of the baseline data from the CLSA

open access: yesFACETS, 2020
To explore whether non-high-density-lipoprotein cholesterol (non-HDL-c) is associated with depression, a total of 26 819 Canadians aged 45–85 from the Canadian Longitudinal Study on Aging (CLSA) were included in analysis.

Wet Strength Resins [PDF]

open access: yes, 1995
Wet strength is defined as a paper which has extraordinary resistance to rupture or disintegration when saturated with water. This definition has been interpreted as if a paper sample retains more than 15% of its dry strength when wetted, it can be ...

Self‐Powered Permeable Electronic Dressing for Exudate Management, Electrostimulation and Drug Delivery in Chronic Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a self‐powered permeable electronic dressing (SPED) that synergistically integrates exudate management, electrical stimulation, and on‐demand drug delivery. The dressing effectively absorbs exudate while demonstrating potent antibacterial activity and accelerated tissue regeneration in diabetic mouse models, thereby promoting ...

A Study of a Method to Predict Printing Quality of Paper by Means of Smoothness and Elongation Test Results [PDF]

open access: yes, 1961
The object of this thesis is to investigate the use of smoothness and elongation test results as criterion for evaluating the printing quality of paper. The relationship of smoothness and printing quality has been known for many years and in all previous

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...
