TL;DR: This work offers a new route for fabricating novel electromagnetic wave absorbers, and the fine balance among lightweight, broad band, and small thickness of the C/TiO2/α-Fe nanocomposites makes them promising in the field of electromagnetic wave absorption.
Abstract: Sandwich-like MXene/Fe3O4 and C/TiO2/α-Fe two-dimensional (2D) nanocomposites were fabricated via in situ hydrothermal assembly of Fe3O4 nanoparticles on MXene nanosheets and postannealing. The as-prepared sandwich-like MXene/Fe3O4 nanocomposites contain uniformly distributed Fe3O4 nanoparticles between the interlayers of the 2D MXene Ti3C2T x nanoflakes. The redox reaction, Ti3C2T x + Fe3O4 → 3TiO2 + 2C + 3Fe, has also been reported for the first time to transform the binary MXene/Fe3O4 nanocomposites into ternary C/TiO2/α-Fe nanocomposites with the 2D structure maintained intact. Such a transition during postannealing gives rise to further enhanced electromagnetic wave absorption compared with that of the MXene/Fe3O4 nanocomposites on top of the already improved performance of the MXene/Fe3O4 compared with that of pristine MXene. The 2D C/TiO2/α-Fe nanocomposites exhibit effective absorption bandwidths of 3.3 and 3.5 GHz at thicknesses of 1 and 1.5 mm, respectively. This work offers a new route for fabricating novel electromagnetic wave absorbers, and the fine balance among lightweight, broad band, and small thickness of the C/TiO2/α-Fe nanocomposites makes them promising in the field of electromagnetic wave absorption.

TL;DR: In this paper, a facile and environmentally friendly 3D printing approach was proposed to fabricate superhydrophobic membranes with an ordered porous structure for oil-water separation using hydrophobic nanosilica-filled polydimethylsiloxane (PDMS) ink.
Abstract: Although superhydrophobic porous membranes are considered to be very promising candidates for oil–water separation, their fabrication methods often involve complicated treatments to build a coating with micro/nano-features on a porous mesh (called “coating on a mesh structure”), which can lead to weak mechanical stability of the superhydrophobic surfaces and the formation of inhomogeneous membrane pores. Herein, we report a facile and environmentally friendly 3D printing approach to fabricate superhydrophobic membranes with an ordered porous structure for oil–water separation using hydrophobic nanosilica-filled polydimethylsiloxane (PDMS) ink. The addition of nanosilica can improve the mechanical strength of the ink and thus ensures the formation of desired topographical structures without the risk of collapsing during 3D printing. Through adjusting the geometrical parameters, a superhydrophobic PDMS membrane was obtained, which mainly depended on the roughness at the sub-millimeter scale. More importantly, the 3D printing approach described herein integrated the superhydrophobic surface into the porous framework and resulted in a mechanically durable superhydrophobic membrane, which successfully avoids the weak interface adhesion issue that arises from the traditional “coating on a mesh structure.” Moreover, the pore size of the printed membrane could be easily adjusted via a computer program to optimize both the liquid flux and separation efficiency of the membranes. The maximum oil–water separation efficiency (∼99.6%) could be achieved for the printed porous membrane with the pore size of 0.37 mm, which also exhibited a high flux of ∼23 700 L m−2 h−1.

TL;DR: In this article, the state of the art in the investigation into ultra-precision machining characteristics of micro-structured functional surfaces with a focus on their typical advanced applications was reviewed.
Abstract: Micro-structured functional surfaces have achieved widespread applications in various advanced scientific, technological, industrial, and engineered fields due to their excellent performances, which are vitally limited by their feasible fabrication. Currently, ultra-precision machining, typically including ultra-precision diamond turning, ultra-precision diamond milling, ultra-precision diamond scratching, ultra-precision grinding, and ultra-precision polishing, is developed as a very-promising solution for the micro-structured functional surface fabrication with high quality, high efficiency, high flexibility, and low cost. Therefore, this paper aims to briefly review the current state of the art in the investigation into ultra-precision machining characteristics of micro-structured functional surfaces with a focus on their typical advanced applications as the significant achievements of their ultra-precision machining fabrication, discuss the key challenges, and further provide new insights into ultra-precision machining of micro-structured functional surfaces for the future research and their further advanced applications.
