Rosin modified aminated mesoporous silica adsorbed tea tree oil sustained-release system for improve synergistic antibacterial and long-term antibacterial effects
TTO antibacterial evaluation mesoporous silica rosin sustained release
2023/12/5
Tea tree oil, a natural antibacterial compound, cannot be used effectively because of its volatile nature. In this work, a biocompatible carrier was prepared and loaded with tea tree essential oil. Th...

Superstructure-Based Simultaneous Optimization of a Heat Exchanger Network and a Compression-Absorption Cascade Refrigeration System for Heat Recovery
Heat Exchanger Network Refrigeration System Heat Recovery
2023/6/19
A heat exchanger network (HEN) plays an important role in the chemical process industry owing to its significant effect in energy recovery. A compression-absorption cascade refrigeration system (CACRS...
Maybe you can’t tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an airplane part to a medical implant. Their n...
If you've ever played soccer with a robot, it's a familiar feeling. Sun glistens down on your face as the smell of grass permeates the air. You look around. A four-legged robot is hustling toward you,...

通道 稳定 纳维-斯托克斯系统
2023/4/27
In this talk, we will discuss some recent progress on steady Navier-Stokes system in a channel, in particular, the problem posed by Leray on steady flows in channels. The existence and uniqueness of s...
Combustion engines, propellors, and hydraulic pumps are examples of fluidic devices — instruments that utilize fluids to perform certain functions, such as generating power or transporting water.
As the world gets warmer, the use of power-hungry air conditioning systems is projected to increase significantly, putting a strain on existing power grids and bypassing many locations with little or ...
Cornell researchers have developed a fairer system for recommendations – from hotels to jobs to videos – so a few top hits don’t get all the exposure.
