This study addresses the issue of waste generation within the food industry, focusing on the conversion of rice husk waste into value-added products. The investigation involves a comprehensive characterization of microcrystalline cellulose extracted from the rice husk and reinforcing them in bio-epoxy resin to determine its feasibility in producing ecofriendly products. The dried rice husk waste was made to undergo a series of treatments, including alkali, acid hydrolysis, and bleaching for extracting high purity microcrystalline cellulose.

Two-dimensional (2D) electronic spectra of the phenylene ethynylene dendrimer with 2-ring and 3-ring branches were evaluated by combining the on-the-fly trajectory surface hopping nonadiabatic dynamics and the doorway-window simulation protocol. The ground state bleach (GSB), stimulated emission (SE), and excited-state absorption (ESA) contributions to the 2D signal were obtained and carefully analyzed. The results demonstrate that the ultrafast intramolecular nonadiabatic excited-state energy transfer (EET) from the 2-ring to the 3-ring units is comprehensively characterized by the SE and ESA signals.

Diffraction-before-destruction imaging with ultrashort X-ray pulses can visualize non-equilibrium processes, such as chemical reactions, with sub-femtosecond precision in the native environment. Here, a nanospecimen diffracts a single X-ray flash before it disintegrates. The sample structure can be reconstructed from the coherent diffraction image (CDI).

Information storage and encryption are the key technologies for modern information transmission. However, most optical information storage technologies based on long persistent luminescent (PersL) only have one fixed response mode, which is easy to imitate, limiting their security in advanced information storage and encryption applications. Besides, the cost of rare earth-doped PersL materials restricts their wide application.

Environmental pollution has been a significant concern for the last few years. The leather industry significantly contributes to the economy but is one of Bangladesh's most prominent polluting industries. It is also responsible for several severe diseases such as cancer, lung diseases, and heart diseases of leather workers because they use bleaching agents and chemicals, and these have numerous adverse effects on human health.
