Abstract In this study, using only a single pulse, pump-probe measurement with large time window of more than 100 ps is implemented. A commercial grating used to encode ∼56 in pulse; therefore, there no need for machining customization. addition, technique, the surface accurately imaged, eliminating image blur problem caused by phase differences previous echelon-based techniques. Moreover, make full use and obtain larger window, simple reflection echelon combined that matches window. This...
Abstract In this research, we studied the ultrafast dynamics and phase transition of VO2 films with different thicknesses. Using transient absorption spectroscopy, two thicknesses 59.5 148 nm showed broadband excited state from 450–750 nm, maximum peak was at ~450 nm. Under low excitation fluences, exhibit three sequential dynamic processes time scales femtoseconds (fs) to nanoseconds (ns). Depending on film thickness fluence, a is observed in scale ~21 ps when fluence reaches 1.27 mJ/cm2....
Aqueous rechargeable manganese (Mn)-ion batteries have recently emerged as a promising candidate for multivalent ion batteries. However, challenges remain, particularly in expanding the electrolyte's voltage window and identifying compatible anode materials. Herein, we introduce Mn-ion full battery comprising nickel hexacyanoferrate (NiHCF) cathode, perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) anode, novel hydrated eutectic electrolyte formulated from Mn(ClO4)2·6H2O acetamide. This...
Abstract Chiral active matter exhibits a variety of collective behaviors, including phase separation, which is governed by the rule “like chiralities attract, while opposite repel”. In this work, we investigate chiral demixing strategy double-chiral partial mixture with inter-chiral frustration. We find that frustration can significantly enhance particles different chirality, both during transient and in steady state, not only accelerating progress, but also improving degree separation. This...
Designing and building unique cage assemblies attract increasing interest from supramolecular chemists but remain synthetically challenging. Herein, we propose the use of a flexible vertex with adjustable angles to selectively form highly distorted tetrahedral octahedral cages, for first time, in which forms synergistic effect coordination covalent interactions. The inherent interligand angle can be modulated by guest anions present, allows fine-tuning different geometries. Furthermore,...
Abstract The overuse of fossil energy reserves emphasizes the necessity for advancement sustainable alternatives. Some functional materials have capacity to directly produce electricity through interactions with ambient humidity, opening up possibilities self‐powered devices. Black phosphorus possesses exceptional physicochemical properties and stability. Herein, fabrication compact flexible moist‐electric generators is explored by directional surficial oxygen defect engineering in black...
Abstract A simple and effective single-shot pump-probe technique is reported for studying ultrafast dynamic processes in various materials. Using only two commercial gratings, a large time window of ~ 95.58 ps spatially encoded single probe pulse, time-resolved measurements are implemented. The this exceeds the maximum values those works using echelon or angle beam encoding strategy. phase difference difficulty strategies also overcome our method, where customized not necessary. ZnSe...
Amplitude Modulation (AM) communication and broadcasting technologies is the first, yet still widely used method of impressing sound on radio. modulation commonly at Long Wave (153-279 kHz), Medium (531-1,611 kHz in ITU regions 1 3, 540-1610 region 2), Short (2.3-26.1 MHz). Signal propagation these bands has unique advantages such as low loss, deep penetration depth, long range, power, etc. Therefore, amplitude been one most methods since it invented. This paper provides an overview history,...

Recently, 2D materials have attracted considerable research attention in nanophotonic and integrated optoelectronic devices due to their intriguing thermal, mechanical, exciton nonlinear optical response. Despite extensive efforts on various (graphene, transition metal dichalcogenides, h-BN, etc.), however, a candidate material with large (NLO) properties, ultrafast response speed, broadband window good thermal stability remains elusive. Black Phosphorus (BP) is representative...
Optical limiting (OL) materials are of great importance for protecting optoelectronic sensors and human eyes from high power laser illumination. Despite extensive efforts on various OL (organic molecules, metal clusters, low dimensional semiconductors, etc.), however, a candidate material with ultrafast response speed, broad protection window large transmission modulation remains elusive.
