Early Spatio-Temporal and Cognitive Deficits in Alzheimer's Disease.

Mental representation of spatial information relies on egocentric (body-based) and allocentric (environment-based) frames of reference. Research showed that spatial memory deteriorates as Alzheimer's disease (AD) progresses and that allocentric spatial memory is among the earliest impaired areas. Most studies have been conducted in static situations despite the dynamic nature of real-world spatial processing.

Although various biochars from different biomass materials have been developed to remediate dye-contaminated environments, the removal capabilities of pristine biochar for dyes urgently require further enhancement due to insufficient surface adsorption sites. To introduce more adsorption sites, this work proposes a simple approach to fabricate coconut shell biochar (CSB) based adsorbent by anchoring zeolitic imidazolate framework-8 (ZIF-8) via the active sites provided by polydopamine (PDA)-coated CSB. The nucleation sites provided by the PDA layer promote the dispersion of ZIF-8 on the surface of CSB, resulting in sufficient adsorption sites for removing malachite green (MG) and rhodamine B (RB) from wastewater.

Biosensors (Basel)

Furong Labratory, Changsha 410083, China.
A fluorescence probe for "switch-on" detection of alkaline phosphatase (ALP) was developed based on Au nanoclusters anchored MnO nanosheets (Au NCs-MnO NSs), which were synthesized using bovine serum albumin (BSA) as template through a simple one-pot approach. In the sensing system, MnO NSs function as both energy acceptors and target identifiers, effectively quenches the fluorescence of Au NCs via fluorescence resonance energy transfer (FRET). The presence of ALP catalyzes the hydrolysis of L-ascorbic acid-2-phosphate (AAP) to ascorbic acid (AA), reducing MnO NSs to Mn and facilitate the fluorescence recovery of Au NCs.

The development of hole-collecting materials is indispensable to improving the performance of perovskite solar cells (PSCs). To date, several anchorable molecules have been reported as effective hole-collecting monolayer (HCM) materials for p-i-n PSCs. However, their structures are limited to well-known electron-donating skeletons, such as carbazole, triarylamine, etc.

Cellulose nanocrystals (CNCs) have emerged as promising, sustainable materials, with applications in sensors, coatings, pharmaceuticals, and composites. Their modification with block copolymers such as PEO-PPO-PEO triblock copolymers of the Pluronic family has been attempted many times in the literature, with claims that such modification would happen by an anchor(PEO)-buoy(PPO)-anchor(PEO) mechanism. However, there is much disagreement in the literature on this.
