Bimetal CuFe Nanoparticles
Bimetal CuFe (copper-iron) nanoparticles, which are based on the earth-abundant and inexpensive metals, have generated a great deal of interest in recent years. The fusion of the unique properties of copper and iron in one single entity may result in the formation of nanocomposites with multifunctional properties (magnetic, catalytic, electrical) and their potential applications in the areas of electronics, photonics, and catalysis.

Bimetallic Nanocrystals
Bimetallic nanocrystals are nanoscale crystals composed of two different metal elements. Bimetallic nanocrystals are expected to exhibit improved physical and chemical properties due to the synergistic effect between the two metals, not just a combination of two monometallic properties, which have important applications in the field of catalysis, energy conversion, gas sensing and bio-detection applications.

Bimetallic Nanomaterials
Bimetallic nanomaterials (BMNs) are one kind of innovative nanomaterials, referring to nano-bimetallic alloy, intermetallic compounds, or the combination of two kinds of metallic nanoparticles. Compared with monometallic nanomaterials, BMNs perform similar or even better physical and chemical properties in the medical field. BMNs possess excellent physical and chemical properties, such as easy surface modification, superior photothermal properties, multiple catalytic properties, delicate sensitivity, and good stability. Synthesis methods of bimetallic nanomaterials. The preparation methods of BMNs commonly used for cancer therapy, such as co-reduction method, hydrothermal method, seed-mediated growth method, and electrodeposition method.

Bimetallic Ni-Based Catalysts CO2 Methanation
CO2 methanation has recently emerged as a process that targets the reduction in anthropogenic CO2 emissions, via the conversion of CO2 captured from point and mobile sources, as well as H2 produced from renewables into CH4. Ni, among the early transition metals, as well as Ru and Rh, among the noble metals, have been known to be among the most active methanation catalysts, with Ni being favoured due to its low cost and high natural abundance. However, insufficient low-temperature activity, low dispersion and reducibility, as well as nanoparticle sintering are some of the main drawbacks when using Ni-based catalysts. Such problems can be partly overcome via the introduction of a second transition metal (e.g., Fe, Co) or a noble metal (e.g., Ru, Rh, Pt, Pd and Re) in Ni-based catalysts. Through Ni-M alloy formation, or the intricate synergy between two adjacent metallic phases, new high-performing and low-cost methanation catalysts can be obtained.

Bimodal Nanostructure
Nanocrystalline metals developed based on fine grain strengthening always have excellent strength, but are accompanied by a drop in ductility. Substantial efforts have been dedicated to design new microstructures and develop the corresponding processing technologies in order to solve this problem. One of the novel nanostructures is the bimodal grain size distribution nanostructure.

Binary Chalcogenides and Their Photocatalytic Water-Splitting Activities
Chalcogenides are essential in the conversion of solar energy into hydrogen fuel due to their narrow band gap energy. H2 is a clean fuel, and its usage can address many of the issues caused by using fossil fuels. It is widely used as a feedstock in the chemical industry to produce ammonia, methanol, and various fuels like diesel, gasoline, etc. It is also used as a transport fuel. It has several other applications in the production of metals and agricultural industries. A cost-effective and long-lasting chalcogenide-based photocatalysts can make the H2 generating process more economical and suitable. The use of binary chalcogenides and their modifications (compounds consisting of only one chalcogen and one electropositive atom) for photocatalytic water splitting will be discussed in the following subsections.

Binders Used for the Manufacturing of Composite Materials
Binders, or tackifiers, have become widespread in the production of new composite materials by liquid composite molding (LCM) techniques due to their ability to stabilize preforms during laying-up and impregnation, as well as to improve fracture toughness of the obtained composites, which is very important in aviation, automotive, ship manufacturing, etc. Furthermore, they can be used in modern methods of automatic laying of dry fibers into preforms, which significantly reduces the labor cost of the manufacturing process.

Binding Materials for MOF Monolith Shaping Processes
The fabrication of porous Metal Organic Framework materials within resistant structures is a key challenge impeding their wide commercial use for processes such as adsorptive separation. In fact, the integration of nano-scale Metal–organic frameworks (MOFs)  crystallic structures into bulk components that can maintain the desired characteristics, for example, size, shape, and mechanical stability, is a prerequisite for their wide practical use in many applications. At the same time, it requires sophisticated shaping techniques that can structure nano/micro-crystalline fine powders of MOFs into diverse types of macroscopic bodies such as monoliths.

Bio-Based Binder Development for Anodes in Lithium-Ion Batteries
The development of rechargeable lithium-ion battery (LIB) technology has facilitated the shift toward electric vehicles and grid storage solutions. This technology is currently undergoing significant development to meet industrial applications for portable electronics and provide our society with “greener” electricity. The large increase in LIB production following the growing demand from the automotive sector has led to the establishment of gigafactories worldwide, thus increasing the substantial consumption of fossil-based and non-sustainable materials, such as polyvinylidene fluoride and/or styrene-butadiene rubber as binders in cathode and anode formulations. Furthermore, the use of raw resources, such as Li, Ni, and Mn in cathode active materials and graphite and nanosilicon in anodes, necessitates further efforts to enhance battery efficiency. To foster a global sustainable transition in LIB manufacturing and reduce reliance on non-sustainable materials, the implementation of bio-based binder solutions for electrodes in LIBs is crucial.

Bio-Based Materials，Antimicrobial Food Packaging
Antimicrobial packaging is a robust technology to provide fresher, safer, and higher quality food products, which concerns about foodborne pathogenic and spoilage microorganisms. It is a form of active packaging (including oxygen scavengers, moisture absorbers, ultraviolet barriers, and other mechanisms delivering antioxidant, flavoring, or antimicrobial activity), and the packaging material interacts with the packaged food in a desirable way. Antimicrobial packaging stands out as an emerging technology that not only prolongs the shelf life of food products but also helps maintain their quality.
