Crystallographic anisotropy, be it inherent or externally induced, profoundly impacts the materials’ physical properties, contributing to their ground-state morphology and magnetic arrangement and fostering distinctive optical behavior. Two-dimensional (2D) materials provide a relatively non-complex platform to study these anisotropy-driven properties. This review explores the intricate relationship between structural anisotropy and the resulting physical phenomena in 2D materials, primarily focusing on 2D hybrid perovskites (2D HPs) and transition metal phosphorous trichalcogenides. Case studies of 2D PEA2PbI4 HPs and FePS3 are provided, explaining how intrinsic structural anisotropy originates and manifests as ground state polymorphism in 2D HPs and zigzag antiferromagnetic arrangement in FePS3. The case of alloyed MnPS3 is examined, where extrinsically induced anisotropy induces magnetic disorder, impacting its magnetic phase stability and overall optical behavior. This account, thus, underscores the origin and significance of intrinsic and extrinsic anisotropy in manipulating materials’ properties.

The relevance of effective mentoring of doctoral students in the chemical sciences is now widely recognized. However, the scholarly literature on the topic is virtually non-existent, and most approaches to faculty education on mentoring are based on “tips” and “guidelines. Following the analysis of current mentorship practices, we suggest a new approach based on evidence resulting from surveys of doctoral students, and on theory derived from studies in social and human sciences.

The 2023 Nobel Prize awarded to Moungi G. Bawendi, Louis E. Brus, and Alexei Ekimov “for the discovery and synthesis of quantum dots” (QDs) marks a milestone in the field to which I devoted the past 30-years of my career. In this perspective, I reflect on key concepts and directions in my research journey. I began by exploring the “artificial atom” nature of QDs while advancing the development of III-V QDs. Shape control, particularly in rods, captured my attention due to its impact on dimensionality related properties. I also discovered semiconductor-metal hybrid nanocrystals and uncovered synergetic effects, highlighting their transformative role in photocatalysis and heavy doping. My work extended to QD applications in displays and, more recently, to forming coupled QD molecules, continuing the artificial atom theme. I conclude by outlining future directions and challenges, envisioning a bright future for this vibrant field at the intersection of materials and physical chemistry.
2023年诺贝尔奖授予Moungi G. Bawendi, Louis E. Brus和Alexei Ekimov“发现和合成量子点”（QDs），这是我过去30年职业生涯中在该领域的一个里程碑。从这个角度，我反思了我的研究之旅中的关键概念和方向。我从探索量子点的“人工原子”性质开始，同时推进III-V量子点的发展。形状控制，特别是在杆，引起了我的注意，因为它对维度相关属性的影响。我还发现了半导体-金属杂化纳米晶体，并发现了协同效应，突出了它们在光催化和重掺杂中的变革作用。我的工作扩展到量子点在显示器中的应用，最近，形成耦合的量子点分子，继续人工原子的主题。最后，我概述了未来的方向和挑战，展望了这个充满活力的领域在材料和物理化学交叉领域的光明未来。

Printed electronics is based on the application of 2D and 3D printing technologies to fabricate electronic devices. To fabricate the printed electronic 2D and 3D devices with the required performance, it is necessary to properly select and tailor the conductive inks, which are often composed of nanomaterials, The main nanomaterials in conductive inks for 2D and 3D printed electronics contain conductive nanomaterials such as metal nanoparticles (NPs) and nanowires and carbon based nanomaterials: carbon black, graphene sheets, and carbon nanotubes (CNTs). All these materials were successfully applied for the fabrication of various electronic devices such as electrical circuits, transparent electrodes, flexible thin film transistors, RFID antennas, photovoltaic devices, and flexible touch panels. In this paper, we focus on the basic properties of these nanomaterials, in view of their application in conductive inks, on obtaining conductive patterns by 2D and 3D printing, and on various methods of post-printing treatment. In the last section, a perspective on future needs and applications will be presented, including emerging technologies.
