Uniformity at scale: Researchers from #RRCAT tackle the challenge of ultra-uniform x-ray mirror coatings—and achieves just 1.87% thickness variation and an incredible 18 nrad slope error across a 300 mm curved surface. doi.org/10.1116/6.0005740

What if we told you there were defects hiding in your deposition process; you just weren't quick enough to see them? A faster simulation method from @CAS__Science reveals how tiny pinholes and voids form during thin-film deposition. doi.org/10.1116/6.0005660

Fast & reliable molecular sensing, coming right up! By stacking magnetic beads & silver nanocubes into a portable nano-sieve, researchers created a powerful platform for stronger, more stable Raman signals—even when detecting multiple molecules at once. doi.org/10.1116/6.0005639

Work smarter, not harder: turn up the temp to cut down on time! 15–30 °C increase in bakeout temp can equal pumping 10× longer; @UCSB authors offer a practical way to optimize vacuum bakeouts while balancing time, thermal budget, & pumping capacity. doi.org/10.1116/6.0005715

Supercharge your plasma activity just by tweaking the plasma's electrical signal! Study shows changing the RF waveform dramatically alters how electrons are heated—& that plasma activity can keep going for tens of nanoseconds after the current reverses. doi.org/10.1116/6.0005607

H₂ can boost SiOCN etching—or shut it down—depending on how it reshapes the plasma & surface chemistry. Authors from @AIST_EN uncover 3 distinct reaction regimes that reveal how to tune H₂ for highly selective SiOCN etching in next-gen 3D logic devices. doi.org/10.1116/6.0005595
