Rhodolirium andicola: a new renewable source of alkaloids with acetylcholinesterase inhibitory activity, a study from nature to molecular docking

open access: yes, 2018
Acetylcholinesterase is an important target for control of neurodegenerative diseases causing cholinergic signaling deficit. Traditionally, galanthamine has been used as an Amaryllidaceae-derived acetylcholinesterase inhibitor, although new ...

Multiscale Carbon‐Integrated Silicon Anode for Stable Cycling Under Practical Lithium‐Ion Battery Conditions

open access: yesAdvanced Energy Materials, EarlyView.
To overcome silicon anode instability, a hierarchical silicon/carbon composite fabricated from industrial waste via a scalable milling process is demonstrated. In‐depth post‐mortem analysis reveals how functional carbons—a CNT network and graphene shell—synergistically suppress degradation. This robust design delivers outstanding stability in practical

The Role of Chemistry Across Disciplines From Humanities to Life Sciences in Understanding Complexity and Emergence

open access: yesAngewandte Chemie, EarlyView.
This study explores the origins of life by linking prebiotic chemistry, the emergence of information‐carrying molecules such as RNA and proteins, and philosophical questions about consciousness. The study emphasizes the role of molecular evolution in the Central Dogma and provides insights into the chemical origins of biology and the basis of life's ...

Diversity of yeasts involved in the fermentation of tchoukoutou, an opaque sorghum beer from Benin [PDF]

open access: yes, 2011
Opaque sorghum beers are traditional alcoholic beverages in several African countries. Known as tchoukoutou in Benin, the beer is often obtained from an uncontrolled fermentation. It is consumed in an actively fermenting state and has a sour taste.

Electric‐Field‐Driven Bilayer Interphase from Oxygenated Nanodiamond‐Carbon Nanoparticles for Dendrite‐Free Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Electric‐field‐driven carbon migration within an oxygen‐functionalized nanodiamond/carbon composite induces the formation of a vertically graded interphase that homogenizes Li‐ion flux and suppresses dendritic nucleation. This hierarchically organized structure stabilizes the electrode–electrolyte interface and delivers durable, dendrite‐free operation

Raoult's Formalism in Understanding Low Temperature Growth of GaN Nanowires using Binary Precursor

open access: yes, 2015
Growth of GaN nanowires are carried out via metal initiated vapor-liquid-solid mechanism, with Au as the catalyst. In chemical vapour deposition technique, GaN nanowires are usually grown at high temperatures in the range of 900-1100 ^oC because of low ...

People and pines 1555–1910: integrating ecology, history and archaeology to assess long-term resource use in northern Fennoscandia

open access: yesLandscape Ecology, 2016
ContextPast human land use has received increasing attention as an important driver of ecosystem change also in seemingly natural landscapes. Quantification of historical land use is therefore critical for assessing the degree of human impact and ...
