Abstract:

Biomass-derived carbon quantum dots (CQDs) were integrated with TiO₂ nanorods to enhance visible-light photocatalytic performance. Photocatalytic performance was evaluated for the degradation of an organic dye and removal of a heavy metal under visible-light irradiation; the incorporation of C-CQDs reduced the band gap of TiO₂ nanorods from 3.11 eV to 2.84 eV, resulting in enhanced photocatalytic performance with 88.04% dye degradation and 88.39% Cr(VI) reduction. In addition, the hybrid photocatalyst showed enhanced antimicrobial activity against Escherichia coli compared with pristine TiO₂, while cytotoxicity assays confirmed acceptable biocompatibility. The C-CQDs/TNRs photocatalyst retained more than 95% of its initial activity after three consecutive reuse cycles, demonstrating excellent stability and reusability. This work demonstrates a promising biomass-to-functional-nanomaterial pathway for multifunctional photocatalytic systems, offering potential for wastewater treatment and microbial disinfection applications.

Water and Mineral Acquisition

Water and Mineral Acquisition

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

States of Water

States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Second Order systems II

Second Order systems II

In an underdamped second-order system, where the damping ratio ζ is between 0 and 1, a unit-step input results in a transfer function that, when transformed using the inverse Laplace method, reveals the output response. The output exhibits a damped sinusoidal oscillation, and the difference between the input and output is termed the error signal. This error signal also demonstrates damped oscillatory behavior. Eventually, as the system reaches a steady state, the error diminishes to zero.

The Water Cycle

The Water Cycle

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.

Quality of Water

Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
