Hazardous Waits: CPSC Lets Crucial Time Pass Before Warning Public About Dangerous Products [PDF]

open access: yes, 2008
Despite a law requiring manufacturers to provide the Consumer Product Safety Commission (CPSC) with "immediate" notification of dangerous products, the agency typically delays nearly seven months after learning of dangerous, defective products before ...

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

open access: yesAdvanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

Giving It a Twist: One‐Step Fabrication of Aligned Biomimetic Yarn Scaffolds via Rotational Melt Electrofibrillation

open access: yesAdvanced Healthcare Materials, EarlyView.
Due to its multifunctionality, replicating the fibrillar and supramolecular architecture of Collagen I is gaining increasing priority in regenerative medicine. Using rotational Melt Electrofibrillation, we present a powerful method to accurately mimic the ultrastructure of Collagen with polycaprolactone, enabling the one‐step fabrication of three ...

Delivery of Multifunctional Microspheres via Intravesical Instillation for Bladder Carcinoma: Therapeutic Potential and Mechanistic Insights

open access: yesAdvanced Healthcare Materials, EarlyView.
PCTM microspheres were successfully synthesized using microfluidic and click chemistry techniques.In Vivo and in vitro experiments have shown that PCTM microspheres have obvious targeting, adhesion, membrane penetration and anti‐tumor properties for bladder tumors.The antitumor mechanism of PCTM microspheres is to indirectly induce S‐stage blockage of ...

Tensile Strength and Failure Characteristics of Common Roof Truss Joints [PDF]

open access: yes, 2002
Timber joints have always been the weak link in timber construction. Although the load carrying capacity of the timber structure is greater than the applied load, the structural system can fail if the joints are weak.

In Vivo Skin 3‐D Surface Reconstruction and Wrinkle Depth Estimation Using Handheld High Resolution Tactile Sensing

open access: yesAdvanced Healthcare Materials, EarlyView.
A compact handheld GelSight probe reconstructs in vivo 3‐D skin topography with micron‐level precision using a custom elastic gel and a learning‐based surface normal to height map pipeline. The device quantifies wrinkle depth across various body locations and detects changes in wrinkle depth following moisturizer application.
