Pancake Lenses through Curved Lamination for Compact Virtual Reality

Advanced Intelligent Systems, EarlyView.
This article presents an ultrathin VR optical system based on a 1.35 in. microdisplay, leveraging curved lamination technology. Compared to mainstream solutions, the proposed design demonstrates superior compactness (volume compression by 12%) and enhanced optical performance.

The upper chromatic number of quasi-interval co-hypergraphs

Le Matematiche, 1997
We investigate the structural and colouring properties of clique hyper-graphs of interval graphs called the quasi-interval hypergraphs. We find the conditions when they are interval hypergraphs. The upper chromatic number for the clique co-hypergraphs of

Efficient Selective Adsorption of Anionic Dyes by Modified Activated Alumina Spheres

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The persistent environmental threat from dye‐contaminated industrial wastewater necessitates advanced remediation solutions. Hydrochloric acid–modified activated alumina spheres (HAAs) are presented as efficient adsorbents for anionic dye removal.

Rhodamine B Adsorption Efficiency of Biochar Produced Through Co‐Pyrolysis of Municipal Sewage Sludge and Food Waste Mixture Under High‐Temperature Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT With the large‐scale construction of wastewater treatment facilities, the production of municipal sewage sludge continues to rise. This sludge contains substantial amounts of toxic and hazardous substances, and improper disposal may lead to secondary environmental pollution.
