Analysis of micro-particles vacuumed from the Turin Shroud

open access: yesMATEC Web of Conferences, 2015
The results of some Turin Shroud particles (3 to 30 µm) examination are presented. A research was performed with the aim to classify the particles in order to correlate them with the environments where, from historical information, the Shroud resulted to

Not all calcite ballast is created equal: differing effects of foraminiferan and coccolith calcite on the formation and sinking of aggregates [PDF]

open access: yes, 2014
Correlation between particulate organic carbon (POC) and calcium carbonate sinking through the deep ocean has led to the idea that ballast provided by calcium carbonate is important for the export of POC from the surface ocean.

Bamboo Medical Application: A State‐of‐the‐Art Review

open access: yesAdvanced Materials Technologies, EarlyView.
This review presents a structured classification of bamboo's current use in healthcare. It organizes applications into medical textiles and medical devices, with further divisions based on function and level of invasiveness. It also examines material utilization based on bamboo's structural role, highlighting how it supports both protective and ...

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

open access: yesAdvanced Optical Materials, EarlyView.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Properties of Nanoscale Particles on the Basis of Metals Localized Into Biological Tissues

open access: yesУспехи физики металлов, 2003
The nanoscale solid-state particles localized into high-mineralised biological tissues (tooth enamel, bone) and into weakly-mineralised tissues (organic tissue of mollusc shells, tissue of brain) are considered.

Cyclodextrin‐Functionalized Light‐Driven Cu2O Micromotors for Simultaneous Capture and Degradation of Bisphenol A

open access: yesAdvanced Robotics Research, EarlyView.
Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.
