Vitamin C‐Assisted Synthesis of Novel Cu‐SSZ‐13 Zeolite and Its High‐Efficiency Performance in Diesel Vehicle NOx Exhaust Purification

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties

Journal of Applied Polymer Science, EarlyView.
Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Deep-learning enabled combined measurement of tumour cell density and tumour infiltrating lymphocyte density as a prognostic biomarker in colorectal cancer

BJC Reports
Background Within the colorectal cancer (CRC) tumour microenvironment, tumour infiltrating lymphocytes (TILs) and tumour cell density (TCD) are recognised prognostic markers. Measurement of TILs and TCD using deep-learning (DL) on haematoxylin and eosin (

Damping scales of neutralino cold dark matter [PDF]

, 2005
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density fluctuations in neutralino cold dark matter (CDM) has a sharp cut-off due
