The contribution of extracellular RNA and its derived biomaterials in disease management
BMEMat, EarlyView.The implications of exRNA's biological function and the structural uniqueness of RNA help establish a close connection between RNA, material, and modern medicine. Abstract The RNA found in the circular system is known as extracellular RNA (exRNA). This kind of RNA has been found to play a biological role similar to that of a messenger. They can be used

The sunspot observations by Toaldo and Comparetti at November 1779 [PDF]
arXiv, 2017 There is a low frequency of sunspot observations in some years of the 17th and 18th century. In particular, the interval 1777-1795 is one of the periods with scarce observations in the databases. In this note, we report a sunspot observation carried out the 3rd November 1779 by Giuseppe Toaldo and Andrea Comparetti.

Features of Separator Configuration in Determining the Cycle Life of Zn Metal Anode
Battery Energy, EarlyView.The separator configuration in zinc‐metal batteries significantly impacts cycle life by influencing internal short circuits from Zn dendrite growth and charge transfer deterioration. This study reveals that the failure mechanism varies with cycling current density and capacity.

ChemPlusChem, Accepted Article.A comprehensive approach was taken to investigate the “Hungarian mine green” pigment, including a historical overview, analysis of the pigment on artworks, and its laboratory replication. It is known that in the past the pigment was collected in wooden reservoirs in which copper (Cu) compounds precipitated from drainage water during copper mining at ...

Newton's Hypotheses on the Structure of Matter [PDF]
arXiv, 2018 Isaac Newton's book 'Opticks' from the 18th century includes several hypotheses on the structure of matter. Most of the hypotheses were confirmed during the 19th and 20th centuries at the scale of atoms and molecules. Conflicts appear however with today's Standard Model of particle physics.

The long-lived effects of historic climate on the wealth of nations [PDF]
We investigate the long-run consequences of historic, climatic temperatures (1730-2000) for the modern cross-country income distribution. Using a newly constructed dataset of climatic temperatures stretching over three centuries (18th, 19th, and 20th ...

The Multiple Facets of Oxalate Dianion in Photochemistry
ChemPhotoChem, Volume 9, Issue 5, May 2025.Oxalate salts have been harnessed in synthetic organic photochemistry as C1‐synthons, SET‐reductants, and hole scavengers. Recent applications focused on reductive functionalizations are herein highlighted. Abstract Oxalate salts are cheap and available reagents used in organic photochemistry as C1‐synthons, single‐electron transfer (SET) reductants ...
