Experiments revealed considerable differences in the mechanical properties of micro/nanomaterials and their macroscale counterparts. In recent years, many researchers have made attempts to develop proper theories addressing these differences and investigate their associated effects on various mechanical behaviors ...
Recent studies have shown that nanoparticle size has a non-trivial role in adhesion to biological cells, cellular uptake and further inhibition of tumor growth.21Generally, the size and shape of inorganic nanomaterials is related to the lattice rearrangement of the surface atoms to minimize the surf...
analyses, we hypothesize that minimizing the particle size may have a negative effect on the electrochemical performance, such that a critical size should exist for electrode materials. In addition, while many nanomaterials used in electrochemical energy storage devices have been synthesized by various ...
The properties of engineered nanomaterials and nanoparticles such as zinc oxide and titanium dioxide may differ substantially from naturally occurring materials and particles. Nanoparticles have unique physical properties making them ideal for use in various skin care products currently on the market. Nano...
The cytotoxicity originates from the intracellular ROS generation and cell membrane disruption, but only the latter is related to size effect.关键词: 2D nanomaterials cytotoxicity membrane disruption ROS RTCA DOI: 10.1002/smll.201770171 年份: 2017 ...
Compared to engineered nanomaterials, sEV have shown many superior physicochemical and biological aspects, such as unmatched biocompatibility, enhanced capacity to cross biological barriers, minimized recognition by reticuloendothelial system and specific tissue targeting [11]. For instance, compared to ...
The finding was gleaned from 10 years of observing dominant male chimpanzees in Gombe National Park, Tanzania, looking at behaviors they used to compete for alpha male status relative to their size. Analysis showed that larger males relied more on physical attacks to dominate while smaller, gentle...

Full size image Results and discussion Generic synthesis of small-sized HMONs Traditionally, large-sized HMONs were prepared through a structural difference-based acid/alkaline etching strategy (Fig.1a)41. When depositing a thin mesoporous organosilica (MON) shell on a large-sized Stöber-based ...
introduces curvature also in the 2nd direction, an undesired effect for these types of SEMRs, because it decreases the effective Lorentz force in the walking direction and complicates the motion, control and fabrication. From these prestretch types, the uniaxial one turned out to be the most ...
