Scientists develop new battery-free lactic acid sensor Scientists at Bath, have introduced a breakthrough carbon-based sensor for detecting lactic acid levels in saliva—avoiding the need for an electrical power source. /news/2024-05-scientists-battery-free-lactic-acid.html Nanomaterials Wed, 22 May 2024 11:54:04 EDT news635597642 In-place manufacturing method improves gas sensor capabilities, production time When used as wearable medical devices, stretchy, flexible gas sensors can identify health conditions or issues by detecting oxygen or carbon dioxide levels in the breath or sweat. They also are useful for monitoring air quality in indoor or outdoor environments by detecting gas, biomolecules and chemicals. But manufacturing the devices, which are created using nanomaterials, can be a challenge. /news/2023-01-in-place-method-gas-sensor-capabilities.html Nanomaterials Fri, 20 Jan 2023 09:34:03 EST news593429641 New catalyst efficiently produces hydrogen from seawater Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen—desirable as a source of clean energy—and of drinking water in arid climates. But even as water-splitting technologies capable of producing hydrogen from freshwater have become more effective, seawater has remained a challenge. /news/2019-11-catalyst-efficiently-hydrogen-seawater.html Materials Science Mon, 11 Nov 2019 12:37:40 EST news492698254 Specific ion effects directed noble metal aerogels Noble metal foams (NMFs) are a new class of functional materials that contain both noble metals and monolithic porous materials for impressive multi prospects in materials science and multidisciplinary fields. In a recent study now published on Science Advances, Ran Du and a team of interdisciplinary researchers in Âé¶¹ÒùÔºical Chemistry, Materials Engineering and Âé¶¹ÒùÔºics developed highly tunable NMFs by activating specific ion effects to produce a variety of single/alloy aerogels. The new materials contained adjustable composition—with gold (Au), silver (Ag), palladium (Pd) and platinum (Pt)—and special morphologies. /news/2019-06-specific-ion-effects-noble-metal.html Materials Science Wed, 05 Jun 2019 10:00:02 EDT news478942022 Lab develops dual-surface graphene electrode to split water into hydrogen and oxygen Rice University chemists have produced a catalyst based on laser-induced graphene that splits water into hydrogen on one side and oxygen on the other side. They said the inexpensive material may be a practical component in generating the hydrogen for use in future fuel cells. /news/2017-08-lab-dual-surface-graphene-electrode-hydrogen.html Materials Science Fri, 04 Aug 2017 00:40:46 EDT news421026024 Scientists produce robust catalyst to split water into hydrogen, oxygen Splitting water into hydrogen and oxygen to produce clean energy can be simplified with a single catalyst developed by scientists at Rice University and the University of Houston. /news/2017-07-scientists-robust-catalyst-hydrogen-oxygen.html Materials Science Wed, 26 Jul 2017 13:29:28 EDT news420294557 Researchers report new, more efficient catalyst for water splitting University of Houston physicists have discovered a catalyst that can split water into hydrogen and oxygen, composed of easily available, low-cost materials and operating far more efficiently than previous catalysts. /news/2017-05-efficient-catalyst.html Materials Science Mon, 15 May 2017 15:00:04 EDT news414065279
