“…The peak at about 675 cm -1 was assigned to the vibration of the Ti-O bond in TiO 6 octahedra [41,42]. The D-and G-bands (corresponding to the in-phase vibration of graphite lattice and disordered or defected graphite) located at ~1350 cm -1 and 1580 cm -1 , respectively, were ascribed to graphene [29,43], suggesting the characteristic of graphene with remained defects that would be the nucleation sites of TiO 2 during the ALD process. No other characteristic peaks could be observed in the spectra, indicating a pure LTO phase without any impurities.…”

High performance composite of nanosized Li 4 Ti 5 O 12 (LTO)and graphene nanosheets wasfabricated using a novel atomic layer deposition (ALD) seeded process incorporated with hydrothermal lithiation for the first time.TiO 2 nanoislands as seeds were anchored on graphene by ALD process, triggering the unique structure formation of subsequent LTO. The synergistic effects of nanosized LTO and graphene endow the composite with a short lithium ion diffusion path and efficiently conductive network for electron and ion transport, boosting the excellent reversible capacity, rate capability, and cyclic stability as anode materials for lithium ion capacitors (LICs). The reversible capacity of 120.8 mAh g-1 at an extremely high current rate of 100 C was achievedsuccessfully, and the electrode can be charged/discharged to about 70% of the theoretical capacity of LTO in 25 s. Meanwhile, the composite exhibited excellent cyclic stability of 90% capacity retention at 20 C with nearly 100% Coulombic efficiency after 2500 cycles. The sintering treatment after hydrothermal reaction has significant effects on the crystallinity, defect density, microstructureandelectrochemical property of the composite, which is also supported by theoreticalcalculations. The results provide a versatile roadmap for synthesis of high performance LTO based composite and new insights into LICs.

The integration of nanotechnology into three-dimensional printing (3DP) offers huge potential and opportunities for the manufacturing of 3D engineered materials exhibiting optimized properties and multifunctionality. The literature relating to different 3DP techniques used to fabricate 3D structures at the macro- and microscale made of nanocomposite materials is reviewed here. The current state-of-the-art fabrication methods, their main characteristics (e.g., resolutions, advantages, limitations), the process parameters, and materials requirements are discussed. A comprehensive review is carried out on the use of metal- and carbon-based nanomaterials incorporated into polymers or hydrogels for the manufacturing of 3D structures, mostly at the microscale, using different 3D-printing techniques. Several methods, including but not limited to micro-stereolithography, extrusion-based direct-write technologies, inkjet-printing techniques, and popular powder-bed technology, are discussed. Various examples of 3D nanocomposite macro- and microstructures manufactured using different 3D-printing technologies for a wide range of domains such as microelectromechanical systems (MEMS), lab-on-a-chip, microfluidics, engineered materials and composites, microelectronics, tissue engineering, and biosystems are reviewed. Parallel advances on materials and techniques are still required in order to employ the full potential of 3D printing of multifunctional nanocomposites.

Outline:Conductive inks are widely investigated area in the recent years due to its popularity in printed electronics (PE), flexible electronics (FE) and it comprises specific and unique applications which belong to a whole next level of future technology. In this context, silver is being acutely researched material for its encouraging application in conductive inks. In printing technology silver conductive inks has major role in electronic applications. The emerging integration of different technologies was silver nanoinks. In recent years printed electronics market is being dominated by expensive materials such as gold, platinum etc.which are costly/complex instruments, to overcome these drawbacks silver conductive inks can relieve the current technology. The present printed circuit boards (PCBs) manufactures use complex and expensive techniques to fabricate the circuit boards which in turn levitates the overall cost. Solvent based silver conductive inks are capable to substitute the PCB technology while reducing the cost of manufacturing. Due to its stellar reputation, investors are looking forward to apply this technology in printed electronics industries.2 planet. Silver conductive inks have silver in its nanoform which is an extensively engaging the nanotechnology.Silver in the nanometer range has predominantly occupied the interest of researchers since the beginning of the nanotechnology era. Silver was and is considered a prominent material;and even historically silver has its own importance. This novel material has been prospering in its applications ever since researchers focused on its study in the nanoscale. This led to a promising application in many fields of science and technology. The properties which make silver notable are that it is rare, strong, corrosion resistant, and unaffected by moisture. Silver is also resonant, moldable, malleable, and possesses the highest thermal and electric conductivity of any substance. Silver is one of the strongest oxidants, it is an essential catalyst for chemical process industry.Metal nanoparticles act as a key element in conductive inks. In nano range, silver has gained so much prominence that it does not require any special introduction about its enhanced properties possessed in the nanometer range. Silver nanoparticles (Ag NPs) have been synthesized using different types of approaches and each type of synthesis has its own advantages and disadvantages. Silver has unique and enhanced properties in the nanometer range by possessing highest electrical conductivity per unit volume when compared to any other metal, so it is expected to be used extensively in printed electronics technology. In this review we try to bring out the possible ways which were successful in synthesis of conductive ink derived from silver nanomaterial. This work is an attempt to understand the significance of silver based conductive inks and motivate researchers who opt to bring a change in future electronics. We focussed this review in gathering a brief preface of all the possible metho...
