The last decade has seen considerable concern regarding a shortage of science, technology, engineering, and mathematics (STEM) workers to meet the demands labor market. At same time, many experts have presented evidence STEM worker surplus. A comprehensive literature review, in conjunction with employment statistics, newspaper articles, our own interviews company recruiters, reveals significant heterogeneity market: academic sector is generally oversupplied, while government private industry...
The academic job market has become increasingly competitive for PhD graduates. In this note, we ask the basic question of 'Are producing more PhDs than needed?' We take a systems approach and offer 'birth rate' perspective: professors graduate who later themselves, an analogue to how population grows. show that reproduction rate in academia is very high. For example, engineering, professor US graduates 7.8 new during his/her whole career on average, only one these can replace professor's...
Abstract Metal‐organic framework (MOF)‐derived architectures are regarded as an effective electromagnetic wave (EMW)‐absorbing materials owing to their adjustable compositions and microstructures. The combination of MOFs with carbon nanofibers (CNFs) is a practical method increase the EMW absorption ability. In this work, cobalt‐based zeolitic imidazolate framework‐67 (ZIF‐67) serves self‐sacrificing precursor fabricate Co‐carbon nanofiber (Co‐CNF) composites via in situ electrospinning...
A novel method is proposed for generating sharper fluorescent super-resolution spot by azimuthally polarized beam in stimulated emission depletion (STED) microscopy. The incoherent superposition of with five-zone binary phase plate and the same quadrant 0/πphase can yield a tightly focused doughnut surrounded completely uniformly. And modulated vortex 0-2π works as pump beam. Compared known effective excitation yielded circular STED beam, result shaper, well energy-saving, costing only ~50%...
The explosive increase in the number of postdocs biomedical fields is puzzling for many science policymakers. We use our previously introduced parameter this journal, basic reproductive academia (R0 ), to make sense PhD population growth fields. Our analysis shows how R0 has increased over time, and we estimate that there approximately only one tenure-track position US every 6.3 graduates, which means rest need get jobs outside or stay lower-paid temporary positions. elaborate on structural...
The interfacial structural design of materials in nanoscale is a promising approach to regulate the physicochemical properties and further optimize material for variety potential applications. Herein, PdNi-S/C nanowires with inductive sulfite has been successfully crafted through hydrothermal synthesis applied as superior hydrogen evolution reaction (HER) catalyst. Based on autocatalytic mechanism, PdNi alloy nanoparticles were synthesized by controlling reduction kinetics presence formic...
Optical control of neural ensemble activity is crucial for understanding brain function and disease, yet no technology can achieve optogenetic very large numbers neurons at an extremely fast rate over a volume. State-of-the-art multiphoton holographic optogenetics requires high-power illumination that only addresses relatively small populations in parallel. Conversely, one-photon techniques stimulate more with two to three orders lower power, but limited resolution or addressable Perhaps...
High-entropy materials (HEM) are expected to make new advances in electrocatalysis and energy storage by virtue of their broad compositional tunabilities, high-temperature stabilities, high chemical stabilities. In recent years, HEM have been investigated extensively these fields, prompting researchers investigate the relationships among structure, composition, electrochemical performance. This paper systematically reviews HEM, focusing on controlled syntheses, atomic-scale structural...
Stimulated emission depletion (STED) microscopy is able to image fluorescence labeled samples with nanometer scale resolution. STED typically a point-scanning method, limited by the high intensity requirement of beam. With development peak power lasers, two dimensional parallel has been developed. Here, we develop theoretical basis for extending three imaging in parallel. This method uses structured illumination (SI) generates pattern. Compared microscopy, 3D SI-STED modulation along light...
Light penetration depth in biological tissue is limited by scattering. Correcting scattering becomes particularly challenging scenarios with photon availability and when access to the transmission side of not possible. Here, we introduce, our knowledge, a new two-photon microscopy system Fourier-domain intensity coupling for correction (2P-FOCUS). 2P-FOCUS corrects modulation Fourier domain, leveraging nonlinearity multiple-beam interference excitation, eliminating need guide star, iterative...
Surface-layer proteins (SLPs) play a crucial role in the self-assembly of bacterial surface layers, yet structural details their assembly domains remain largely unexplored. Here, we report crystal structure SlpM_C1, module within domain SlpM from Lactobacillus brevis . SlpM_C1 adopts β-grasp fold, conserved motif found diverse protein families. Structural comparisons with ubiquitin and SlpA_II L. acidophilus reveal both shared distinct features, highlighting elements convergence despite...
Multimodal imaging of fluorescence and phase provides distinct complementary insights into biological samples. Current multimodal techniques for simultaneous fluorescent primarily operate in transmission mode are limited to thin samples, restricting their applications bulky tissues vivo animals. While multiphoton microscopy has enabled deeptissue imaging, integrating it with remains challenging due the availability methods capable reconstructing 3D refractive index (RI) bulky, label-free...
