Waking up with a pimple is no longer cause for panic, thanks to pimple patches — small, sticker-like bandages that cover and help heal the unwanted zit. A team of researchers publishing in ACS Applied Materials & Interfaces has designed a two-stage pimple patch set with an array of tiny spikes that grabs onto the pimple and delivers antibacterial or anti-inflammatory compounds. Human clinical trials confirmed that the pimples completely disappeared after seven days of treatment.

Looking to improve zinc production? Scientists have developed a new model that can quickly and accurately predict temperatures in industrial roasters using minimal data. This innovation could enhance efficiency and product quality in zinc smelting. Find out how it works and its potential impact in our latest report!

Lithium-rich oxides are widely regarded as one of the most promising cathode materials for next-generation lithium-ion batteries, but their potential has been hampered by rapid performance degradation. Now, researchers have developed a protective LiF@spinel dual shell that dramatically improves their stability. The spinel layer acts as a fast highway for lithium ions, while the outer LiF layer serves as a shield against corrosive electrolytes. Working in tandem, the two layers prevent structural collapse and suppress damaging side reactions. With this innovation, the modified cathode demonstrates outstanding cycle life and capacity retention, opening a new path toward reliable high-energy batteries.

The performance of a battery depends not just on what it’s made of, but also on how it’s built. A new study reveals that the thickness of boride films—critical components in all-solid-state thin-film lithium batteries (TFLBs)—directly governs voltage behavior, capacity, and long-term stability. By experimenting with cobalt–boron (CoB), iron–boron (FeB), and cobalt–iron–boron (CoFeB) alloys at varying thicknesses, researchers found that thinner films promote uniform lithium-ion distribution, reduce polarization, and enhance reaction kinetics, resulting in steeper yet more stable voltage profiles. The findings offer a unified theory connecting thickness, composition, and lithiation behavior—providing a straightforward strategy to design next-generation, high-performance energy storage devices.

Light still holds surprises – as demonstrated by researchers from the Ultrafast Phenomena Lab at the Faculty of Physics, University of Warsaw, in collaboration with the Institute of Low Temperature and Structure Research, the Polish Academy of Sciences, who have discovered a new enhancement effect in the emission of upconverting nanoparticles. They demonstrated that simultaneous excitation of these nanostructures with two near-infrared beams of laser light leads to a significant increase in emission intensity. Under carefully chosen conditions, visible emission emerges only when both beams are applied together, even though neither beam alone produces any emission at all. This discovery paves the way for visualizing infrared radiation beyond the sensitivity range of standard detectors. The findings, potentially applicable in microscopy and photonic technologies, have been published in the prestigious journal “ACS Nano”.

Recently, Prof. JIANG Changlong’s research team from the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, used multi-emission metal organic framework hydrogel (Eu-Dy MOF gel) to construct a non-invasive wearable eye patch fluorescence sensor, combined with the color recognition function of a smartphone to analyze and monitor lysozyme in tears.
