Enhanced hydrogen-gas permeation through rippled graphene
Wenqi Xiong, Weiqing Zhou, Pengzhan Sun +1
The penetration of atomic hydrogen through defect-free graphene was generally predicted to have a barrier of at least several eV, which is much higher than the 1 eV barrier measure…
HRS-Bench: Holistic, Reliable and Scalable Benchmark for Text-to-Image Models
Eslam Mohamed Bakr, Pengzhan Sun, Xiaoqian Shen +3
In recent years, Text-to-Image (T2I) models have been extensively studied, especially with the emergence of diffusion models that achieve state-of-the-art results on T2I synthesis…
ImageCaptioner: Image Captioner for Image Captioning Bias Amplification Assessment
Eslam Mohamed Bakr, Pengzhan Sun, Li Erran Li +1
Most pre-trained learning systems are known to suffer from bias, which typically emerges from the data, the model, or both. Measuring and quantifying bias and its sources is a chal…
Highly Efficient and Selective Extraction of Gold by Reduced Graphene Oxide
Fei Li, Jiuyi Zhu, Pengzhan Sun +8
Materials that are capable of extracting gold from complex sources, especially electronic waste (e-waste) with high efficiency are needed for gold resource sustainability and effec…
Structure Evolution of Graphene Oxide during Thermally Driven Phase Transformation: Is the Oxygen Content Really Preserved?
Pengzhan Sun, Yanlei Wang, He Liu +4
A mild annealing procedure was recently proposed for the scalable enhancement of graphene oxide (GO) properties with the oxygen content preserved, which was demonstrated to be attr…
Ultrafast Liquid Water Transport Through Graphene-Based Nanochannels Measured by Isotope Labelling
Pengzhan Sun, He Liu, Kunlin Wang +3
Graphene-based laminates, with ultralong and tortuous nanocapillaries formed by simply stacking graphene flakes together, have great promises in filtration and separation. However,…
