Photographs of Mary Pauline Root

open access: yes, 1920
Photographs of Mary Pauline Root most likely during her time as a missionary in Japan around 1891 and while visiting American Indian communities and Indian Government Schools teaching social hygiene for the U.S. Bureau of Indian Affairs in 1920.

Titanium dioxide nanoparticles (TiO2-NPs) effect on germination and morphological parameters in alfalfa, tomato, and pepper

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca
Titanium dioxide nanoparticles are used in different processes, derived from this their presence in wastewater is common, concentrating in residual sludge. These residues are used as agricultural soil improvers, being a source of crop exposure.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

open access: yesAdvanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Conformal Thermoreversible Gelatin‐Based Gel for High‐Fidelity Electrophysiological Recording and Acute Peripheral Nerve Interfacing

open access: yesAdvanced Materials, EarlyView.
A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.

Branched root hairs in Miconia albicans (sw.) Triana (Melastomataceae)

open access: yes, 2006
The protrusion of the outer wall of a rhizodennal cell represents the first visible stage in the development of a root-hair. Every root-hair consists of an unbranched cylindrical tube with a rounded tipo Root hairs are almost always unicellular.

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds

open access: yesAdvanced Materials, EarlyView.
We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

All‐Amyloid Functional Coacervates

open access: yesAdvanced Materials, EarlyView.
This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.
