The preparation of a novel iron/manganese binary oxide

To remove hexavalent chromium Cr(VI) efficiently, a novel Fe–Mn binary oxide adsorbent was prepared via a "two-step method" combined with a co-precipitation method and hydrothermal method.The as-prepared Fe–Mn binary oxide absorbent was characterized via transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared

Mechanisms of mechanical reinforcement by graphene

The exceptional mechanical properties of graphene can be attributed to the hexagonal lattice of graphene and the stability of the sp 2 bonds during various types of in-plane deformations. The work of Hone and coworkers 11 first revealed the mechanical properties of graphene through calculating the breaking force of graphene under an AFM nanoindenter.

Journal of The Electrochemical Society, Volume 167,

The initial specific capacity and capacity retention rate of graphite/LiNi 0.6 Co 0.2 Mn 0.2 O 2 punch cells employing this electrolyte are 169.3 mAh g −1 and 98.7% (after 50 cycles), respectively, which are comparable to those of cells employing traditional

Thermal and Mechanical Properties of Microporous

Microporous polyurethanes (MPU) were modified by adding 0.25%–1.25 wt% of reduced graphene oxide (RGO). The materials were prepared without solvent via in situ polymerization. From a technological point of view, it is very important to obtain functional

A Review of Graphene

2021/1/4The mechanical production of graphene generally involves the production of graphene sheets via exfoliation or the separation of highly ordered pyrolytic graphite (HOPG). Advancements in the scotch tape method and AFM technologies means that graphene can be produced on scales ranging from 10 to

3. Manufacturing: Materials and Processing

These features translate into poor mechanical properties and low-value products, that is, incompatibility. When this is the case, strategies for achieving compatibility are sought, generally employing block or graft copolymers to be located at the interface, much like surfactants.

Journal of Physics: Conference Series, Volume 1781, 2021

Some mechanical properties of treated Ti-6Al-4V alloy such as micro hardness and ductility were investigated. Ti-6Al-4V-xNb (x = 1, 2 and 5 wt.%) alloys were produced. The influence of Nb contents on microstructure characteristics and mechanical properties showed that the addition of Nb in Ti-6Al-4V alloy persuaded the formation of new phase distributing at grain boundaries.

Power Ultrasonic Additive Manufacturing: Process

Despite the need to understand the mechanical properties of AM as-built parts, there is still the challenge of directly comparing the properties of materials fabricated by different AM techniques. This is due to the many processing parameters, type of material fabricated, application, and presence of different types and quantity of defects, as well as the limitations associated with various AM

2018/2/23Thermal mechanical analyzer (TMA) was used to analyze the mechanical properties of the composite. The tensile properties of PTFE and PTFE composites (nano-SiO 2 ) were measured and it shows the difference in modulus, tensile strength, and elongation at break at a different weight percent (wt.%) of PTFE/Nano-SiO 2 .

Graphene Modified Multifunctional Personal Protective

Many researchers suggest that textiles used in PPE may act as vehicle for the acquisition and spreading of microorganisms. Soft surfaces of apparel are often contaminated with pathogens that can cause infectious diseases. 18 Pathogens grow well in moist conditions and in protein‐enriched biological waste that might be present on HCW PPE. 19 Pathogens can survive on the PPE, which can be

Mechanical properties of graphene and graphene

2017/10/1The impressive mechanical properties of graphene are one of the reasons that make graphene stand out both as an individual material and as a reinforcing agent in composites. The reason for the exceptional mechanical properties of graphene lies in the stability of the sp 2 bonds that form the hexagonal lattice and oppose a variety of in-plane deformations.

It was concluded that ultrasonic techniques are sensitive to the changes in the graphite morphology, thus they can also be used to predict the mechanical properties. The ultrasonic techniques eliminate the need for preparation and destructive testing of specimens, furthermore, they can be carried out in a few minutes, and are cost effective.

Solid-state-batteries (SSBs) present a promising technology for next-generation batteries due to their superior properties including increased energy density, wider electrochemical window and safer electrolyte design. Commercialization of SSBs, however, will depend on the resolution of a number of critical chemical and mechanical stability issues. The resolution of these issues will in turn

Microbial Safety of Wood in Contact with Food: A Review

The physical properties of wood (for example, mechanical strength, elasticity, thermal conductivity) are strongly related to the water content below the FSP, but hardly above the FSP (Monteiro 2014). Dry wood, as used in most technical applications, has a moisture content below 19%, while green wood contains from 60% to 200% water (Greer and Pamberton 2008 ).
