Background: In 2017, the US Department of Veterans Affairs (VA) implemented the Life-Sustaining Treatment Decisions Initiative (LSTDI), which created a portable and durable code status for use across its health care system. Patients who now have a durable do not resuscitate (DNR) status may undergo invasive procedures. Few studies have examined whether proceduralists discuss DNR status and document changes before procedures.

- A systematic study was conducted on metal-assisted chemical etching (MacEtch) to create vertical silicon (Si) microwire arrays, focusing on optimizing various parameters like metal film thickness and morphology.
- The resulting Si microwires reached lengths of up to 23.2 μm and showed improved performance when used in solar cells, achieving a conversion efficiency of 13.0%, an open-circuit voltage of 547.7 mV, and a short-circuit current density of 33.2 mA/cm².
- This research demonstrates that using MacEtch for high-quality Si microwires can lead to the development of affordable and efficient solar cell technology.
Article Synopsis
- Conventional color sensors use organic dye filters for color imaging, but they are less durable, have low absorption capability, and are complex to make.
- A new method using all-silicon nanowire devices eliminates the need for filters, creating pixels with vertical silicon nanowires that act as photodetectors.
- The new approach allows the capturing of color by tuning the nanowire radius, increasing photon efficiency and changing the way light is converted into electrical signals.
