Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells

open access: yesAdvanced Materials Technologies, EarlyView.
Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

Ultrafast (1‐5 sec) Lamination of Perovskite Solar Cells With Self‐Encapsulation Using Rapid Joule Heating

open access: yesAdvanced Materials Technologies, EarlyView.
Halide perovskite solar cells are fabricated with self‐encapsulation by lamination between two glass substrates using rapid Joule heating, yielding a 99% reduction in lamination time compared to previous studies. An 18% efficient cell is laminated in 5 s, demonstrating the potential for scalable manufacturing. ABSTRACT Perovskite solar cells (PSCs) are

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant

open access: yesAdvanced Materials Technologies, EarlyView.
A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

Hand Washing

British Journal of Perioperative Nursing (United Kingdom), 2000
What could be more basic than the simple act of washing your hands? Children at junior school are taught to do it. Yet research tends to point to the lack of hand washing as being a major contributor to hospital acquired infection. I have summarised this piece by Elizabeth Pinney which takes us right back to the 18th century - and bang up to date ...

Hand washing

Nursing Standard, 2016
A surgery matron has writt en a hand hygiene promotional video rap to encourage staff, patients and visitors to wash their hands. Vicky Cartwright from University Hospitals of Leicester NHS Trust rewrote the lyrics to 1990s hit rap, Ice Ice Baby.

Surgical hand‐washing

Annals of the College of Surgeons of Hong Kong, 2004
Pre‐operative hand‐washing is essential for the reduction of surgical site infection (SSI) rate. This article aims to review the current literature regarding the issues on: (i) the duration of washing; (ii) the use of the brush; and (iii) the reagents used.

On Washing Hands

New England Journal of Medicine, 2004
One afternoon last December, I took a tour of my hospital with Deborah Yokoe, an infectious-disease specialist, and Susan Marino, a medical technologist by training. They work in our infection-control unit. Their full-time job is to stop the spread of infection in the hospital.
