Evaluation and Zoning of Severity and Danger of Desertification in the Some Parts of Sistan Plain and Hamoon Lake Bed Using IRIFR Model Dr. Ahmad Pahlavanravi Assistant Professor of Geomorphology University of Zabol [PDF]

open access: yesجغرافیا و توسعه, 2012
Introduction According to Glantz,s  theory, desertification term  has about one hundred definitions(Glantz, 1977) . The common point in all these definitions is the severe demolition of the environment due to desertification..Some of these definitions ...

Unlocking Long‐Lived Charge‐Separated State in Pentamethine Cyanine Based on Anionic Hofmeister Effect for Photodynamic Immunotherapy

open access: yesAdvanced Science, EarlyView.
Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

Methodology for assessing the productivity index change in oil wells (case study of the vereian deposits in Perm Region)

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов
Relevance. The vereian deposits of Perm Region are characterized by heterogeneous geological structure, and the wells producing from them exhibit a rapid decline in fluid production rates during the initial production period. This complicates both short-

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

open access: yesAdvanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Magnetoreceptor Promotes Hepatocellular Carcinoma Development and Blunts Sorafenib‐Induced Ferroptosis by Regulating Iron Homeostasis

open access: yesAdvanced Science, EarlyView.
Magnetoreceptor (MagR) regulates iron homeostasis and mitochondrial function in hepatocellular carcinoma (HCC) cells. Specifically, MagR deficiency suppresses tumor cell proliferation, migration, and invasion and enhances sorafenib‐induced ferroptosis through iron accumulation.

Prophage Activation Triggers Extracellular Synthesis of DNA in Bacterial Biofilms via Rolling Circle Replication

open access: yesAngewandte Chemie, EarlyView.
Shewanella oneidensis and Bacillus subtilis, both harboring prophages, reveal a novel biosynthetic route to scalable and programmable DNA superstructures in flower‐ and wire‐like shapes, respectively. Activation of prophages is achieved via 3‐hour starvation and monitored using reporter strains.

Electrodeposited Piezoelectric Chitosan Films: A New Approach Toward a Scalable and Standardized Fabrication of Sensors

open access: yesAdvanced Electronic Materials, EarlyView.
Electrodeposition is explored as an innovative and scalable approach to fabricate standardized and highly piezoelectric chitosan films. Chitosan deposition is driven onto gold‐coated silicon plates by an applied voltage. Films’ piezoelectricity is clearly proved and correlated to the material structural order.

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers

open access: yesAngewandte Chemie, EarlyView.
A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...
