The transition from a linear economy to a circular carbon economy urgently requires sustainable and efficient technologies for converting non-fossil biomass and waste plastics into fuels and high-value chemicals. Solar-driven photocatalytic technology has emerged as a promising strategy due to its mild reaction conditions and potential for selective transformation, which addresses the limitations of traditional recycling and conversion methods (e.g., high energy consumption, harsh conditions, and poor selectivity). However, current photocatalytic valorization systems still suffer from insufficient activity and selectivity, mainly due to the inability to precisely regulate reaction pathways. Considering that selective bond activation (especially C–H and C–C bond activation) is the key determinant, this review focuses on the photocatalytic valorization of biomass and plastics, classifies reaction pathways based on dominant bond selectivity, and mainly emphasizes the contrast between C–H and C–C bond activation. This classification approach overcomes the limitations of traditional substrate-based classification, providing new insights for the rational design of highly selective photocatalytic systems to realize the valorization of biomass and waste plastics.
People with severe asthma are often battling multiple health conditions that go undetected, say scientists. A study found that nearly all patients suffer from at least one other major health issue, while most are juggling three or more conditions.
The Strategic Materials Accelerator & Research Testbed (SMART) will serve as a national hub for cutting-edge biotechnology research, providing organizations with tools to develop, test and scale breakthrough technologies, accelerating solutions that directly strengthen national defense and power the innovations of tomorrow.
Summary:
Texas Tech University broke ground on the Critical Infrastructure Security Site at the Reese National Security Complex, expanding its role in protecting the nation’s critical infrastructure systems. The site positions Texas Tech as a growing national hub for cybersecurity, cyber-physical defense and interdisciplinary partnerships focused on addressing emerging threats to infrastructure security.
Why This Matters:
Forefront of Protection: The new site strengthens research and innovation aimed at protecting critical systems such as the electrical grid, water utilities, communications and military infrastructure from evolving threats.
Workforce Development: Texas Tech is building a pipeline of skilled cybersecurity and defense professionals through hands-on training, federal partnerships and programs that engage students and current industry workers.
Leadership in Research: The Critical Infrastructure Security Institute elevates Texas Tech’s role as a leader in critical infrastructure protection, leveraging expertise in cybersecurity, energy and cyber-physical systems to support national resilience.
Current laws are not doing enough to protect the environment or public health against toxic per- and polyfluoroalkyl substances (PFAS), warns a new study.
PFAS are a family of nearly 15,000 synthetic chemicals used in everyday products since the 1950s, from non-stick cookware and waterproof clothing to firefighting foam. Because they are extremely resistant to breaking down, they build up in the environment and in living organisms, earning their nickname 'forever chemicals'.
New research, the latest in an ongoing partnership between the University of Portsmouth and the Marine Conservation Society tested for PFAS in the Solent, a stretch of water between Portsmouth and the Isle of Wight.
