In this study scanning near-field optical microscopy (SNOM) has been utilised in conjunction with quantum dot labelling to interrogate the biomolecular composition of cell membranes.The technique overcomes the limits of optical diffraction found in standard fluorescence microscopy and also yields vital topographic information.The technique has been
Mechanical effect of clay under the acid-base action: A case study on montmorillonite and illite
To study the mechanical effect of clay under acidic and basic conditions, typical clay minerals, montmorillonite and illite, were taken as the main research objects in this study.The variation law and mechanism of the cohesive force and internal friction angle were studied by immersing the remoulded soil in HNO3 solution with pH = 3 and NaOH (alkal
From giant to dwarf: A trend of decreasing size in Panthera spelaea (Goldfuss, 1810) and its likely implications
The Eurasian fossil record of Panthera spelaea shows Baby Shampoo a gradual decrease in body size.The process peaking just before the extinction of the species at the end of the Late Pleistocene.The temporal trend of decreasing size particularly accelerating during MIS 2, as exemplified by the extremely small female skull from Kryshtaleva Cave.Some
