Alternatives for Uranyl Acetate Negative Staining With Respect to the Resolution Obtained After Single Particle Analysis of Erythrocruorin

Microscopy Research and Technique, EarlyView.
This study explores the efficiency of lanthanide‐based negative stains for studying single molecules with TEM, under the scope of replacing the hazardous UAc. We show that NdAc, EuAc, and UA‐Zero stains are great alternatives as they efficiently contrast protein molecules in a given range of pH and allow the 3D reconstruction of proteins at 30, 24, and

Effect of P rates in long‐term conservation agriculture trials on the vertical distribution of soil acidity and nutrient availability

Journal of Environmental Quality, EarlyView.
Abstract Few studies are published on the long‐term impact of phosphorus (P) rates as triple superphosphate (208 g P kg−1) on the vertical distribution of soil acidity and the availability of macro and micronutrients within conservation systems. This study explores the long‐term impacts of increasing P rates on the vertical distribution of soil acidity

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Semi-Quantitative Analysis of Uranium Content Distribution Ratio in a Sandstone-Type Uranium Deposit in Songliao Basin

Yankuang ceshi
The Qianjiadian uranium deposit is a complex-metamorphic sandstone-type uranium mine located in the southern part of the Songliao Basin. To determine the state of uranium mineralization and its partitioning in different minerals, petrographic ...
