“…It is well-known, that creation of hybrids and nanocomposites, having properties that are not typical for microscale materials, is a promising way to design an advanced electrodes for LIBs. Additionally, as it was shown previously, the usage of Sn or Pb in a form of oxides [6,7], chlorides [8,9], fluorides [10], sulfides [11,12], etc. facilitate the volume stresses due to the formation of damping matrices during initial alloying process (1).…”

In the present paper, a composite containing mixed oxides of tin and lead has been synthesized by the method of pulsed high-voltage discharge. Material was characterized by X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray analysis and transmission electron microscopy. The composite consists of SnO2 and PbO particles with an average size of ~350 nm, and SnPb2O4 nanowhiskers with size of 100 nm in diameter and few microns in length. The electrochemical performance of nanocomposite as a potential anode of lithium-ion battery has been investigated by the cyclic voltammetry and galvanostatic charge/discharge test in the potential range of 3.0–0.005 V. The reversible capacity of 821 mA·h/g was realized after 5-fold cycling at a current density of 100 mA/g. It was established that further cycling of the material is accompanied by a dramatic capacity fade: only 13 % of the initial capacity was obtained already after 10 cycles. The observed degradation in performance of nanocomposite results from its inability to compensate large lithiation/delithiation-induced volume expansion.

Lead chalcogenide nanocrystals (NCs) are an emerging class of photoactive materials that have become a versatile tool for fabricating new generation photonics devices operating in the near-IR spectral range. NCs are presented in a wide variety of forms and sizes, each of which has its own unique features. Here, we discuss colloidal lead chalcogenide NCs in which one dimension is much smaller than the others, i.e., two-dimensional (2D) NCs. The purpose of this review is to present a complete picture of today’s progress on such materials. The topic is quite complicated, as a variety of synthetic approaches result in NCs with different thicknesses and lateral sizes, which dramatically change the NCs photophysical properties. The recent advances highlighted in this review demonstrate lead chalcogenide 2D NCs as promising materials for breakthrough developments. We summarized and organized the known data, including theoretical works, to highlight the most important 2D NC features and give the basis for their interpretation.

“…In literature, only few research groups' report the synthesis of PbSe NSs, however, the thickness of the reported NSs is not enough to show the quantum confinement effect. 83,84 Here, we have developed a novel synthesis method for synthesizing the quantum confined PbSe NSs of sufficient thickness. The setup, as shown in Figure 2.4 was enacted by carving out a parallel cavity in a domestic microwave oven that allowed a quartz enclosure with an outer diameter of 19 mm to pass through it.…”

Many people at NTU played smaller but no less critical roles in helping me. Prof. Phan A. Tuan and Dr. Ranjan Singh, who have been very generous to me in giving me tremendous moral support. I would also like to thank my friends Ankur, Yogesh, Govind, Kamesh, Gurudayal and James, that have brought me tremendous joy and have made my life outside the lab unforgettable.Most importantly, special thanks to my family; that is always a source of inspiration for me.They have been a great source of joy and support, and I will love them always. I would have never made it without their help. I do not have words to express the feeling indebtedness to them.My heartfelt appreciation to my wife Sakshi Singh who understands and supports me.
