Solvent effects on the electronic structure, excited states, and nonlinear optical properties of two anthracene-based chalcone derivatives: a DFT and TD-DFT study

Solvent effects on the electronic structure, excited states, and nonlinear optical properties of two anthracene-based chalcone derivatives: a DFT and TD-DFT study

Renato Medeiros

What if the liquid around a molecule could change not just how it absorbs light, but which of two molecules appears more powerful? This study finds that the answer can switch with the solvent.

High-throughput study of electrical conductivity in ordered metals

High-throughput study of electrical conductivity in ordered metals

Thalis H. B. da Silva, Hai-Chen Wang, Tiago F. T. Cerqueira, Simone Di Cataldo, Silvana Botti, Miguel A.L. Marques

Every phone, power line, and computer depends on electricity moving easily through metal. This study asks whether a computer can search millions of possible compounds and uncover conductors that could rival the best metals we already use.

Performance analysis of a metal hydride reactor for hydrogen storage using ethylene glycol-based coolants as heat transfer fluids

Performance analysis of a metal hydride reactor for hydrogen storage using ethylene glycol-based coolants as heat transfer fluids

Hydrogen can store energy for heavy transport and industry, but storing it is not as simple as filling a tank. A coolant choice may shorten the storage cycle, while demanding far more pumping power.

Sub-nanosecond structural dynamics of the martensitic transformation in Ni-Mn-Ga

Sub-nanosecond structural dynamics of the martensitic transformation in Ni-Mn-Ga

Yuru Ge, Fabian Ganss, Daniel Schmidt, Daniel Hensel, Mike J. Bruckhoff, Bruno Neumann, Mariana Brede, Sakshath Sadashivaiah, Markus E. Gruner, P. Gaal, Klara Lünser, S. Fähler

Some metals can change their internal structure almost instantly, and that motion can power tiny machines. This study finds a complete switching cycle in just five nanoseconds.

Superconductivity of barium with highest transition temperatures in metallic materials at ambient pressure

Superconductivity of barium with highest transition temperatures in metallic materials at ambient pressure

Masaki Mito, Hiroki Tsuji, Takayuki Tajiri, Kazuma Nakamura, Yongpeng Tang, Zenji Horita

A material that normally needs crushing pressure to become superconducting can keep that special state after the pressure is gone. In barium, the result reaches twenty-four kelvin at ordinary pressure.

Assessment of the oxidative stress intensity and the integrity of cell membranes under the manganese nanoparticles toxicity in wheat seedlings

Assessment of the oxidative stress intensity and the integrity of cell membranes under the manganese nanoparticles toxicity in wheat seedlings

Apolonia Sieprawska, Elżbieta Rudolphi-Szydło, Magdalena Skórka, Anna Telk, Maria Filek

Tiny manganese particles sprayed onto wheat leaves did not simply sit on the surface. They entered the leaves, triggered a stress response, and quietly changed the membranes inside the plant.

Electrical and magnetic properties of antiferromagnetic semiconductor MnSi2N4 monolayer

Electrical and magnetic properties of antiferromagnetic semiconductor MnSi2N4 monolayer

Dongke Chen, Zhengyu Jiang, Ying Tang, Junlei Zhou, Yuzhou Gu, Jingjing He, Jiaren Yuan

Imagine a sheet so thin that its electrons can be made to choose sides: one direction flows like metal, while the other is blocked like a semiconductor. This study predicts a material that can do exactly that.

Preparation and Characterization of a Novel Self-Healing Transparent Polyimide Film Based on Dynamic Disulfide Bonds

Preparation and Characterization of a Novel Self-Healing Transparent Polyimide Film Based on Dynamic Disulfide Bonds

Xin Li, Yan Zhai, Kai Yang, Jingjing Bai, Yu Qiu, Yulong Wang

A scratch on a flexible screen can threaten the whole device. This study tests a clear plastic film that can close its own scratches when heated, while staying strong and transparent.

Copper-Nanoparticle-Induced Neurotoxic Effect and Oxidative Stress in the Early Developmental Stage of Zebrafish (Danio rerio)

Copper-Nanoparticle-Induced Neurotoxic Effect and Oxidative Stress in the Early Developmental Stage of Zebrafish (Danio rerio)

Na Liu, Luyao Tong, Kunjie Li, Qiuxia Dong, Jieying Jing

Copper nanoparticles are used in products people encounter every day. In developing zebrafish, they were linked to abnormal growth, disrupted nerve signaling, oxidative stress, and inflammation.

Atherosclerosis treatment with nanoagent: potential targets, stimulus signals and drug delivery mechanisms

Atherosclerosis treatment with nanoagent: potential targets, stimulus signals and drug delivery mechanisms

Ting Luo, Zhen Zhang, Junbo Xu, Hanxiong Liu, Lin Cai, Gang Huang, Chunbin Wang, Yingzhong Chen, Long Xia, Xunshi Ding, Jin Wang, Xin Li

Heart disease kills at least nearly one in three people worldwide, yet the drugs used to fight artery disease can miss the damaged area or harm other organs. This review explores a striking alternative: tiny carriers that may find the trouble and open their medicine there.

Machine Learning Interatomic Potential for Modeling the Mechanical and Thermal Properties of Naphthyl-Based Nanotubes

Machine Learning Interatomic Potential for Modeling the Mechanical and Thermal Properties of Naphthyl-Based Nanotubes

Hugo X. Rodrigues, Hudson R. Armando, Daniel A. da Silva, João Paulo C. L. da Costa, Luiz Antônio Ribeiro, Marcelo Lopes Pereira

A tiny carbon structure can stay intact at temperatures far beyond ordinary industrial heat, yet snap suddenly when stretched. This study builds a faster way to find out exactly where those limits lie.

A tiny drop of water can reveal a dangerous pollutant without a large laboratory machine. This sensor turns the drop itself into a simple warning signal: the brighter light disappears when hexavalent chromium is present.
