Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

Advanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...

Trace metals and the elderly

Clinics in Geriatric Medicine, 2002
The elderly are at nutritional risk as a result of multiple physiological, social, psychological, and economic factors. Elderly persons have a higher incidence of chronic diseases and associated intake of medications that may affect nutrient utilization.

Trace metals in hematopoiesis

American Journal of Hematology, 1981
AbstractThe trace metals represent an extremely small part of the total mass of the organism. In spite of this, these elements appear to play major roles in metabolism. At the level of the hematopoietic system, specific roles can be identified for iron, copper, zinc, and cobalt.

Trace Metals in Neuropsychiatry

British Journal of Psychiatry, 1983
Naylor's recent hypothesis that vanadium ‘poisoning’ could be a factor in the severity of manic-depressive illness drew attention to the normal and even essential presence of vanadium in the diet, and in human living tissues. The whole brain may contain only about 45 micrograms of vanadium (Underwood, 1977; 1979), as against 500 micrograms of manganese,
