Phys.org November 13, 2024 Researchers in India demonstrated that zinc in nano form (Zn Nano) and chelated form (Zn EDTA) effectively alleviates stress, improves photosynthetic efficiency and protects the photosynthetic apparatus. The study highlighted the crucial role of the xanthophyll cycle pigments—violaxanthin, antheraxanthin, and zeaxanthin—in dissipating excess light energy, with zinc treatments enhancing their protective effects under stress. The study also discussed the possible roles of Zn binding chloroplastic proteins in water stress alleviation. According to the researchers their findings underscore the potential of zinc foliar sprays, particularly in nano form, as an effective strategy to boost drought resilience in […]

Valley-transistor in two-dimensional materials – an ingredient for all-optical quantum technologies
Nanowerk April 23, 2023 Electrons in two-dimensional materials possess an additional quantum attribute, the valley pseudospin, labeled as K and K’—analogous to the spin up and spin down. Most of the research to achieve valley-selective excitations in valleytronics depends on resonant circularly polarized light with a given helicity. Not only acquiring valley-selective electron excitation but also switching the excitation from one valley to another is quintessential for bringing valleytronics-based technologies to reality. Researchers in India introduced a coherent control protocol to initiate valley-selective excitation, de-excitation, and switch the excitation from one valley to another on the fly within tens of […]
Almost ready for prime time: Deep UV photodetectors head to real-world testing
Phys.org April 19, 2022 Researchers in India did a broad assessment of the performance of AlGaN and Ga2O3 photodetectors based on the material quality. They introduced a new comprehensive figure of merit (CFOM) to benchmark photodetectors by accounting for their three most critical performance parameters, i.e., gain, noise, and bandwidth. According to their benchmark AlGaN detectors do not have any serious shortcoming that is holding them back from entering the market. They tried to identify the gaps that exist in the research landscape of AlGaN and Ga2O3 solar-blind photodetectors and argue that merely improving the material/structural quality and device performance […]
Self-Detoxifying Wearable Filter for Development of Next Generation NBC Protective Gear
Global Biodefense January 2, 2022 Researchers in India have developed a highly effective self-detoxifying filter consisting of in-situ immobilized Zirconium hydroxide [Zr(OH)4] over woven activated carbon fabric [Zr(OH)4@W-ACF] for the removal of CWAs. It harnesses the synergistic effect of high surface area of the woven activated carbon fabric dispersing CWAs. The kinetics of in-situ degradation of CWAs over Zr(OH)4@W-ACF were found to be following the first-order reaction kinetics. The potential practical applicability of this work was established by fabricating Zr(OH)4@W-ACF as reactive adsorbent layer for protective suit and found to meet the specified criteria in terms of air permeability, tearing […]
